Description

Technical Field

[0001] This utility model relates to the field of building construction equipment technology, and in particular to a grouting pipe that can be used in the fields of foundation grouting reinforcement and grouting water plugging and seepage prevention. Background Technology

[0002] In the construction of foundation grouting reinforcement and grouting water plugging and seepage prevention projects, direct grouting in the hole is affected by factors such as soil porosity, permeability and grouting pressure, which makes it difficult to achieve uniformity in the flow and diffusion of grout in the hole. This can result in local situations where there is too much or too little grout, affecting the foundation reinforcement and water plugging and seepage prevention effect.

[0003] Most existing grouting pipes still use the whole-section construction and grouting method, which involves grouting the entire pipe after installation in the hole. This construction method is relatively simple, but the soil conditions are different in different parts of the hole, and the diffusion speed and range of the grout vary. It is difficult to keep the grouting pressure constant throughout the grouting process. As the grout is injected, the pressure in the hole gradually increases, which may lead to excessively high or low grouting pressure. However, it is impossible to achieve precise control of the amount of grout injected, and it is difficult to achieve a uniform grouting effect. Utility Model Content

[0004] The purpose of this invention is to overcome the defects in the prior art and provide a grouting pipe with a separator, so that the grout can be evenly distributed in the grouting area, filling the pores and fissures of the formation, and improving the density and strength of the formation.

[0005] The purpose of this utility model is achieved as follows: a grouting pipe with a separator includes a grouting pipe body and a separator disposed on the grouting pipe body. The separator includes a connecting pipe, a top pipe sleeved above the inside of the connecting pipe, and a bottom pipe sleeved below the inside of the connecting pipe. The ends of the top pipe and the bottom pipe that meet inside the connecting pipe are respectively sealed with small pieces of geomembrane bags. The joints of the top pipe, the bottom pipe and the connecting pipe are respectively fixed by welding. The part of the top pipe extending outside the connecting pipe has a grouting hole. The surface of the grouting hole is provided with a geomembrane bag. The ends of the top pipe and the bottom pipe outside the connecting pipe are threaded sections for connection.

[0006] When this utility model is in operation, by connecting a separator to the grouting pipe body, the grouting holes on the separator allow grout to enter and form the effect of external segmentation of the grouting pipe, while the grouting holes on the grouting pipe body allow grout to enter and form the effect of internal segmentation of the grouting pipe. With this device, the effect of simultaneous segmentation of the grouting pipe inside and outside can be achieved, thereby improving the grouting effect and quality.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0008] First, during foundation grouting reinforcement and grouting water plugging and seepage prevention construction, the grout reaches the small geomembrane strips of the separator through the grouting pipe. The grout solidifies, forming a segmented effect inside the grouting pipe. At the same time, the grout flows into the cylindrical geomembrane bag through the grouting hole of the jacking pipe, solidifies inside the geomembrane bag, and forms a segmented effect outside the grouting pipe. The grouting pipe with separator forms a segmented effect both inside and outside the pipe, so that the grout can be evenly distributed in the grouting area, filling the pores and fissures of the stratum, improving the density and strength of the stratum, and improving the effect and quality of grouting.

[0009] Secondly, when using the grouting pipe of this device, the installation position of the separator on the grouting pipe can be changed according to the grouting depth, making it convenient to use.

[0010] Third, this device has a simple structure, is easy to install and disassemble, has low manufacturing cost, and can be made using materials available on-site.

[0011] Furthermore, both ends of the grouting pipe are threaded joints, and a number of grouting holes are circumferentially opened on the surface of the grouting pipe, with adjacent grouting holes being equidistantly spaced.

[0012] Furthermore, the joint at one end of the grouting pipe is connected to the threaded section at one end of the jacking pipe by a steel hoop. A cylindrical geomembrane bag is also fitted over the separator, and the two ends of the cylindrical geomembrane bag are tied and fixed to the grouting pipe and the bottom pipe respectively by steel wire.

[0013] Furthermore, the grouting pipe is a seamless steel pipe.

[0014] Furthermore, the top pipe, connecting pipe, and bottom pipe are of the same length, and the outer diameter of the top pipe and bottom pipe is less than or equal to the inner diameter of the connecting pipe. Attached Figure Description

Detailed Implementation

[0020] like Figures 1-4 The grouting pipe shown includes a grouting pipe body 13 and a separator 11 disposed on the grouting pipe body 13. The separator 11 includes a connecting pipe 2, a top pipe 1 sleeved inside the upper part of the connecting pipe 2, and a bottom pipe 3 sleeved inside the lower part of the connecting pipe 2. The ends of the top pipe 1 and the bottom pipe 3 that meet inside the connecting pipe 2 are respectively sealed with small pieces of geomembrane bags 4. The joints of the top pipe 1, the bottom pipe 3 and the connecting pipe 2 are respectively fixed by welding. The part of the top pipe 1 that extends out of the connecting pipe 2 has a grouting hole 6. The surface of the grouting hole 6 is provided with a geomembrane bag 8. The ends of the top pipe 1 and the bottom pipe 3 outside the connecting pipe 2 are threaded sections 10 for connection.

[0021] Both ends of the grouting pipe body 13 are threaded connectors 12. Several grouting holes 7 are circumferentially opened on the surface of the grouting pipe body 13, and adjacent grouting holes 7 are equidistantly arranged.

[0022] The joint 12 at one end of the grouting pipe body 13 is connected to the threaded section 10 at one end of the jacking pipe 1 by a steel hoop 14. A cylindrical geomembrane bag 9 is also fitted outside the separator 11. The two ends of the cylindrical geomembrane bag 9 are tied and fixed to the grouting pipe body 13 and the bottom pipe 3 by steel wire. The grouting pipe body 13 is a seamless steel pipe.

[0023] The jacking pipe 1, connecting pipe 2, and bottom pipe 3 are of the same length. The outer diameter of the jacking pipe 1 and the bottom pipe 3 is less than or equal to the inner diameter of the connecting pipe 2, which facilitates the insertion of the jacking pipe 1 and the bottom pipe 3 into the connecting pipe 2.

[0024] During assembly, the grouting pipe of this invention has a threaded section 10 at one end of the top pipe 1 and the bottom pipe 3, which connects to the grouting pipe body 13. The other ends are sealed with small pieces of geomembrane bags 4, and the sealed end is inserted into the connecting pipe 2. The parts are then joined together in the connecting pipe 2 and welded together. A grouting hole 6 is opened on the part of the top pipe 1 that extends out of the connecting pipe 2. A geomembrane bag 8 is wrapped around the surface of the grouting hole 6 with cable ties. The threaded section 10 of the top pipe 1 is then joined to the joint 12 of the grouting pipe body 13 and connected and fixed with a steel hoop 14. Finally, a cylindrical geomembrane bag 9 with open ends is tied to the grouting pipe body 13 and the bottom pipe 3 with steel wire. The middle part of the cylindrical geomembrane bag 9 is wrapped and fixed to the bottom pipe 3, the connecting pipe 2, the top pipe 1, and the grouting pipe body 13 with electrical adhesive. During foundation grouting reinforcement and grouting water plugging and seepage prevention construction, the grout reaches the small geomembrane bag 4 of the separator 11 through the grouting hole 7 on the grouting pipe 13. The grout solidifies into blocks, forming the effect of internal segmentation of the grouting pipe 13. At the same time, some grout flows into the cylindrical geomembrane bag 9 through the grouting hole 6 on the jacking pipe 1. The grout solidifies into blocks, forming the effect of external segmentation of the grouting pipe 13. With this device, the effect of internal and external segmentation of the grouting pipe 13 can be achieved simultaneously, so that the grout can be evenly distributed in the grouting area, filling the pores and cracks of the stratum, improving the density and strength of the stratum, and improving the effect and quality of grouting.
