The grouting pipe is used as the pipe for grouting at the bottom of the pile. The test shows that the bearing capacity of the cast-in-place pile treated with the pile bottom grouting can be greatly improved At the same time, it is necessary to take measures to punch the pipe at the defect position where grouting is required. The classification of the grouting pipe can be divided into three categories according to the pipe materials: the advantages of steel pipe steel pipe are that it is easy to install and it can be welded on the reinforcement frame by electric welding, and because of the large rigidity of the steel pipe After embedding, the parallelism and straightness can be basically maintained. At present, many large-diameter cast-in-place piles use steel as the grouting pipe. However, the price of steel pipe is relatively expensive: steel corrugated pipe steel corrugated pipe is a better grouting pipe material. It has the characteristics of thin pipe wall less steel, impermeability, pressure resistance, high strength and good flexibility. It is usually used for post tensioning reserved holes in prestressed structures: when used as grouting pipe. It can be directly bound to the reinforcement framework soil, and the joint can be connected with a larger corrugated sleeve. Since the bellows is light, it is very convenient to operate, but attention should be paid to keeping its axis straight during installation.Appropriate measures shall be taken to prevent surface water, curing water and garbage from falling in. When necessary, a sump shall be set near the post cast strip of the base plate in combination with the design of the basement plane drainage system to facilitate the final cleaning before the grouting pipe is cast. When advance water stop is not used, a sump shall be set, which can be set in the basement according to the above method, or set outdoors as a temporary facility. Usually, we use the waterproof scheme between the grouting pipe and the water surface or before, so as to determine a complete implementation scheme of advanced water stop before the excavation of the foundation pit and the pouring of the cushion. Otherwise, the design modification requirements will be put forward only when problems are found in advance water stop during construction which will affect the integrity and rationality of the whole water stop scheme.Monday repurchase, curtain grouting of dam foundationPolymer chemical grouting method is applicable to reinforcement of sandy soil foundation, water stop and leakage stoppage of underground engineering, reinforcement of muddy interlayer of dam foundation and fault fracture zone. There are many varieties of polymer chemical pulp materials, including epoxy resin, acrylamide (propionate), polyurethane (cyanogen), lignin, etc. Acrylamide and polyurethane are commonly used in chemical grouting of foundation. Acrylamide pulp is composed of main agent acrylamide and various admixtures. The viscosity of the slurry is close to water, and it has good groutability. After the slurry solidifies, the gel is impermeable, and has good durability and stability. This kind of slurry is widely used in seepage prevention grouting of fine rock cracks and medium fine sand layers and dynamic water leakage stoppage projects. This kind of pulp has certain toxicity and pollutes air and groundwater. The polyurethane slurry is mainly composed of polyisocyanate and polyether resin, and then mixed with various admixtures. After the slurry is poured into the formation, it reacts with water to form polyurethane foam, which can strengthen the foundation and prevent seepage and leakage. Polyurethane slurry can be divided into water-soluble and non-water-soluble. The water-soluble polyurethane can be miscible with water and react with water to form an aqueous gel; Water insoluble polyurethane can only be miscible with organic solvents. Polyurethane slurry has low viscosity, good groutability, high stone strength, safety and reliability, no pollution to the environment, simple operation and high economic benefits.In limestone area, the punching is not good, and it is difficult to sink the reinforcement cage. When the grouting pipe is deformed and blocked by unconventional means, the pipe is blocked due to the workers&#; carelessness and falling into small concrete blocks. The deformation and blockage of the grouting pipe bring great difficulties to the detection work, and even can not be detected. Therefore, effective measures should be taken to pass the pipe to ensure the smooth progress of ultrasonic inspection. Generally there are three methods for passing the pipe: stabbing the grouting pipe with thick and long reinforcement, flushing and pigging with high-pressure water, and using a drill with a small drill to clean the hole.Batu Gajah, The grouting pipe is padded with the front lip of the horseshoe, and the height of the saddle shaped curved surface is changed to make the pipe wall crawl and slide along the accurate saddle shaped curved surface.They shall be connected as a whole in the factory as far as possible. If it is necessary to connect on site due to manufacturing process, transportation conditions, etc., hot press vulcanization (grouting pipe) or welding (plastic grouting pipe) shall be used. The joint appearance shall be smooth and smooth, and the tensile strength shall not be less than % of the base metal. The so-called 'overlapping' without any treatment is absolutely not allowed. All kinds of cross connection points of grouting pipes shall be made of accessories produced by our new rubber products factory, so as to ensure that on-site connection is only carried out in straight sections during construction. Flexible material with sufficient deformation capacity and good adhesion with concrete.In China, the types of grouting pipes are relatively complete now, from grouting pipes and grouting pipes for Reinforcing Subgrade to glass fiber grouting pipes for highway pavement, to convex joint grouting pipes and plastic tensile grouting pipes for railway. For different road construction environments, different types of grouting pipes are selected, which can not only ensure the quality of the road but also save the cost. So what kind of application effect can the grouting pipe achieve in highway maintenance? The grouting pipe manufacturer will take you to have a look.

Grouting pipe grouting pipe manufacturer clamp type grouting pipe grouting pipe price grouting pipe spot grouting pipe specification grouting pipe model grouting pipe raw material for grouting pipe grouting pipe is processed by welded pipe or spiral steel pipe, and grouting pipe processed by seamless steel pipe is generally rare in the market. The reasons are as follows: first, in terms of price, generally, the cost of grouting pipes made by welding is relatively low, which is easy for purchasers to accept. The cost of domestic products made of spiral steel pipes and seamless steel pipes is too high. Second, in terms of processing technology, welded pipes are relatively easy to process, and the equipment required is relatively simple. If spiral steel pipes and seamless steel pipes are processed, it is also commonly called clamp down grouting pipe. The clamp grouting pipe has the following characteristics: the connection of the grouting pipe is simple, as long as the hydraulic clamp is required for connection. The grouting pipe has joints at both ends of the clamp type grouting pipe, which avoids the possibility of loosening and has good seismic resistance. Several common failures in the installation of grouting pipes always have many problems when using grouting pipes for work. In order to enable everyone to provide production to the factory normally, we have specially summarized the following failures that will occur when using grouting pipes. If you have problems in the following examples you will know how to solve them The first point is that if the joint, nozzle or bottom of the grouting pipe is not tightly sealed, it will be blocked by cement slurry during construction. At this time it is OK to check the sealing The second point is that the joint is misaligned or deformed during installation. At this time, we need to know that it is caused by the thin material selected. The above two points are common problems in the installation of grouting pipes that are not suitable for the current location. We&#;d better remember these points of attention, so that when they occur in the future, we will know how to deal with them to ensure a quick solution! The grouting pipe joint or the pipe orifice and the pipe bottom are not sealed tightly, so please bring in mud or cement slurry during the construction process to block the pipe: during the installation and grouting of the grouting pipe, the rebar is distorted or collided, causing the dislocation and deformation of the grouting pipe joint or the deformation of the pipe wall. The main reason for this is the selection of thin-walled grouting pipes.[invention content] [] in view of the shortcomings of the prior art, the utility model provides a fast cutting device in the hole of the underground grouting pipe in order to solve the problems of the prior art, which can reduce the operating intensity of workers by using the lead screw principle, reduce the quantities of clearing the roadway floor by using the rotary cutting in the casing, and adjust the cutting depth at will according to the actual situation of the roadway.The use of grouting pipes has become indispensable in modern building construction, ranging from super high-rise and high-rise buildings to multi-storey buildings and indoor decoration construction. China has a longer history of using grouting pipes. Many of China&#;s ancient buildings have been listed as world-class material and cultural heritage, because China&#;s ancient buildings are very technical in construction. In China, before and in the early s, grouting pipes made of bamboo and wood were used in the construction of buildings. After the mounting bracket is welded on the surface of the grouting pipe, push the strain gauge in a stable and free state without bending and twisting; The mounting bracket and strain gauge shall be installed parallel to the support axis; When tightening the screw, pay attention to reasonably controlling the frequency of the strain gauge; The installation position of the strain gauge shall be selected at the position suitable for protection as far as possible.Installation works, The overhead type is a special rack installed at the bottom of the driving head and connected with the wellhead tensioning equipment.The grouting pipe diffuses the load on it. When the reinforced soil is loaded, the grouting pipe has a high bond with the soil, and has a mutual embedding effect with the soil, making the reinforced soil a tensile member, spread the load stress evenly to a large base range enhance the overall tensile strength of the soil, and effectively improve the stress distribution of the pavement structure. The strength of high tensile reinforced soil is far higher than that of unreinforced soil,Monday repurchase48lead small conduit, greatly improving the bearing capacity of the soil.The research shows that the friction between the grouting pipe and the soil is also greatly related to the water content and compactness of the soil. The grouting pipe itself has a pattern, and is also a grid like integral geo reinforced material, so the friction between the grouting pipe and the medium is very large; The grouting pipe also has a great tensile strength, a large deformation modulus, and the reinforcement is stable and uniform, which can see good results in a short time. It can be seen from the experiment that the mesh reinforcement performance of the grouting pipe is better than the strip reinforcement material, which increases the stability of the project; The grouting pipe is especially suitable for the construction of high-speed highways, because the action force of the back and forth traffic on the soil is very great, and the grouting pipe can share the stress, increase the deformation modulus of the soil, effectively enhance the strength of the soil, and achieve the effect of stabilizing the project and long-term use.

The cutting blade is shown in Fig. How heavy is a grouting pipe?Monday repurchase,Grouting pipe grouting mainly improves the bearing capacity of piles from these two aspects Grouting is carried out through the grouting pipe embedded in the pile body. The slurry integrates the soil and slurry around the pile body through penetration, splitting and compaction, so as to improve the physical and mechanical properties of the bearing layer of the pile body Especially for the ballast at the bottom of the pile, grouting can improve or eliminate the adverse effect of the ballast at the bottom of the pile on the end bearing capacity through the replacement, compaction and consolidation of the ballast by the slurry.II During the drilling process of the bored pile, which will lead to the decrease of the pile side friction and affect the bearing capacity of the pile When the grouting pipe is used at the pile end for grouting, the slurry will permeate, fill and compact along the side of the pile under the pressure, so as to complete the replacement of the mud skin around the pile and the filling of the gap, such as greatly improving the pile side friction resistanceBefore the installation of the grouting pipe, it is necessary to check whether the processed support is vertical to the grouting pipe fitting, and correct the non vertical support; Then install the grouting pipe on the bracket and fasten it.In limestone area, the punching is not good, and it is difficult to sink the reinforcement cage. When the grouting pipe is deformed and blocked by unconventional means,Monday repurchaseHollow self-propelled anchor rod manufacturer,Monday repurchaseGrouting pipe, the pipe is blocked due to the workers&#; carelessness and falling into small concrete blocks. The deformation and blockage of the grouting pipe bring great difficulties to the detection work, and even can not be detected. Therefore, when the grouting pipe is found blocked after the foundation pile is poured and before the inspection, effective measures should be taken to pass the pipe to ensure the smooth progress of ultrasonic inspection. Generally, there are three methods for passing the pipe: stabbing the grouting pipe with thick and long reinforcement, flushing and pigging with high-pressure water, and using a drill with a small drill to clean the hole.
