Advantages: It is connected with special hydraulic tongs, does not require preparations outside the construction site, does not require any equipment, is convenient and fast ( times faster than the traditional welding method), is simple to fix the grouting pipe to the reinforcement cage, and is not affected by the bad weather.How heavy is a grouting pipe?Guadalupe, The grouting pipe has good air tightness, low gas permeability, strong sealing and no leakage.The grouting pipe at the tensioning end has good anchoring energy and self anchoring energy. Grouting pipe is generally used for tensioning. The grouting pipe at the tensioning end is composed of four parts: clip, anchor plate,GuadalupeAdvance small conduit and pipe shed, anchor base plate and spiral reinforcement. The clip is the key part of the anchoring system. It is two-piece and made of high-quality alloy steel.Ventspils,The foundation pit excavation shall strictly follow the principle of 'layered excavation'. The support erection shall be closely coordinated with the earthwork excavation. During the excavation, the earthwork near the grouting pipe shall be excavated by the central trenching method to prevent the machinery from colliding with the support; The earthwork near the slope protection pile shall be excavated manually with small machines and tools. It is forbidden to collide with the grouting pipe and bored pile by mechanical excavation. After the earthwork is excavated to the design elevation, the grouting pipe shall be erected and prestressed in time to reduce the exposure time without support. The overhead type is a special rack installed at the bottom of the driving head and connected with the wellhead tensioning equipment.Answer: it varies according to the model and elasticity of the grouting pipe, and its internal pressure can reach bar or more.

There are many forms of grouting pipes that can be improved and applied. Although the engineering pipeline system is very complex, any complex pipe system can be divided into several relatively simple individual pipe sections through the setting of fixed pipe racks. When selecting the corrugated grouting pipe, the deformation compensation of the pipe system can be determined according to these relatively simple pipe sections, so as to select the grouting pipe.[] in one embodiment, as shown in Fig. , the flange I is used for the installation and connection of the utility model and the underground grouting pipe. The fast cutting device of the utility model rotates the bolt by using the fastening force acting on the bolt,GuadalupeGrouting flower tube, and the fixed cutting device can be moved up and down through the screws on the bolt. There are screw patterns on the outer surface of the cutting rotary device and on the upper end of the tension blade device The tension blade nut can be directly screwed to one end of the tension blade device A cutting blade and a pulley are fixed to the lower end of the cutting rotary device , and the outer diameter of the cutting rotary device is smaller than the inner diameter _ of the sleeve. The specification of the utility model can be made into a series of products according to different specifications of the grouting pipe. Glass fiber grouting pipe is a semi-rigid product made of glass fiber as raw material, high-strength alkali free glass fiber through a certain warp knitting process, and fiber filament coated on both sides.Latest quotation,The longitudinal overlapping width of grouting pipe and grouting pipe shall not be less than cm, and the transverse overlapping width shall not be less than cm. The former shall be placed on the latter according to the asphalt paving direction. After laying the glass fiber grouting pipe, fix the glass fiber grouting pipe with high-quality cement nails and fixed iron sheets with a size of mm, mm and a thickness of .mm. The fixed spacing can be determined according to the actual construction situation. Classification of grouting pipe grouting pipe the grouting pipe is a plane mesh material of grouting pipe with certain flexibility. The main raw material is polyethylene grouting pipe. It is extruded into thin sheets by a grouting pipe extruder, and then punched with regular holes. Then it is made by directional stretching under the control of heating. It can be divided into unidirectional grouting pipe and bidirectional grouting pipe according to the different stretching modes when it is manufactured. After the two pipes are connected by using the deformation of the grouting pipe, the kneading part of the joint is large at both ends and small in the center, so that the joint is stuck at one time, avoiding the possibility of loose union. The grouting pipe has proper, stable and excellent s in terms of tensile pull-out and torque resistance, and the protrusion is circular arc with small protrusion, which is useful to avoid collision with conduits, vibrators etc.

The grouting pipe at the tensioning end has good anchoring energy and self anchoring energy. Grouting pipe is generally used for tensioning. The grouting pipe at the tensioning end is composed of four parts: clip, anchor plate anchor base plate and spiral reinforcement. The clip is the key part of the anchoring system. It is two-piece and made of high-quality alloy steel.Installation material list, the development of the production technology of automobile door and window sealing strips is the most representative. Through the introduction of sealing strip production lines from JapanAmong the many imported projects Germany, Italy, Britain and other countries, domestic manufacturers have introduced more than sealing strip production lines. In addition to pure rubber sealing strips, sealing strips of various composite structures, rubber and plastic composite sealing strips can be produced. At present, the overall level of China&#;s sealing strip production technology has basically reached the level of foreign countries in the s, and has become a grouting pipe. Because some projects are not easy to detect when they are manufactured, and the quality of the grouting pipe as a channel for testing instruments has become crucial. If the quality of the grouting pipe is poor, it will bring many hidden dangers. Steel grouting pipe material, which has the characteristics of thin pipe wall, steel saving, impermeability, pressure resistance and high strength, is generally used for post tensioned reserved holes in prestressed structures. When the grouting pipe is used, it can be directly bound to the reinforcement framework. Because the grouting pipe is very light, it is very convenient to operate. However, attention should be paid to the balance of its axis during installation.The grouting pipe is divided into one-time grouting pipe and the repetitive grouting pipe is a embedded grouting pipe system, which is used for permanent sealing of construction joints, cold joints, it can be sealed by injecting slurry into the PVC port set on the surface. The proper grouting time can be selected after the concrete curing. Leakage joints can also be sealed in this way.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, 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.Guadalupe, performance of grouting pipe the grouting pipe is light in weight, has strong bite force with soil or gravel, is acid-base resistant, corrosion-resistant, aging resistant and easy to construct. It has high tensile strength (- times higher than that before stretching) and low elongation (only % - % of that before stretching). It is easy to cut and connect on site (polyethylene rope or connecting rod can be used for connection), the grouting pipe has low hardness and the bending effect during construction is small. However, poor mechanical damage resistance, and mechanical scars such as scratches and crushed stones will produce stress concentration, which will reduce the overall mechanical properties of the grouting pipe and the grouting pipe. Sometimes the grouting pipe is overlaid on the two sides of the horseshoe surface. Adjust the cooperation specifications of the grouting pipe at the distribution nozzle. How to avoid grout leakage during installation of grouting pipe? 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.
