Description

Technical Field

[0001] This utility model relates to the field of grouting pipe technology, specifically a mining grouting pipe that is easy to install. Background Technology

[0002] During construction, grouting pipes are commonly used to reinforce the ground with grout. To prevent soil loosening around the foundation pit and to fill any gaps not filled during the first grouting, secondary grouting is required. Since the grouting pipe remains inside the foundation pit after the first grouting, grout and sediment from the pit can flow back into the pipe, clogging the grouting holes. This hinders the smooth flow of grout during the secondary grouting, affecting the grouting effect.

[0003] For example, Chinese patent application number 202320610674.8 describes a grouting pipe. This patent uses a sealing component to prevent soil, sand, and grout from flowing back into the grouting pipe or clogging the injection holes. Since the grouting pipe remains inside the pit after grouting, and a large number of grouting pipes are needed on-site, installing a sealing structure in each grouting hole to prevent grout backflow would be very costly to manufacture. Such grouting pipes are expensive and unsuitable for mass production. Therefore, a mining grouting pipe that is easy to install is proposed. Summary of the Invention

[0004] The purpose of this utility model is to provide a mining grouting pipe that is easy to install, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mine grouting pipe that is easy to install, comprising a grouting pipe body, a first grouting hole on the grouting pipe body, a conical head fixedly connected to the bottom of the grouting pipe body, a second grouting hole on the conical head, a sealing pipe inside the grouting pipe body, a through hole on the sealing pipe, a sealing head fixedly connected to the bottom of the sealing pipe, a connecting ring fixedly connected to the top of the sealing pipe, a plug at the bottom of the connecting ring, and a slot adapted to the plug at the top of the grouting pipe body.

[0006] As a further preferred embodiment of this technical solution: a sleeve is connected to the grouting pipe body, the sleeve has an internal thread, a partition is provided in the middle of the sleeve, and a first external thread that engages with the internal thread is provided at the top of the grouting pipe body.

[0007] As a further preferred embodiment of this technical solution: the sleeve is connected to an extension rod, one end of the extension rod is provided with a second external thread that engages with the internal thread, and the end of the extension rod away from the second external thread is provided with a third external thread.

[0008] As a further preferred embodiment of this technical solution: the outer diameter of the connecting ring is the same as the outer diameter of the grouting pipe body, the size of the first grouting hole is the same as the size of the through hole, the insert and the slot are respectively provided in four sets and evenly distributed, the through hole is located directly below the insert, and the first grouting hole is located directly below the slot.

[0009] As a further preferred embodiment of this technical solution: the outer diameter of the sleeve is the same as the outer diameter of the grouting pipe body.

[0010] As a further preferred embodiment of this technical solution: the outer diameter of the extension rod is the same as the outer diameter of the grouting pipe body, and the second external thread and the third external thread have the same dimensions.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, by setting a sealing pipe, with the sealing head at the bottom of the sealing pipe cooperating with the connecting ring at the top, the insert block and the slot, allows the sealing pipe to seal the first grouting hole of the grouting pipe body when grouting is not performed, effectively preventing mud and sand from flowing back into the grouting pipe or blocking the grouting hole, thereby ensuring the smoothness of secondary grouting.

[0013] 2. This utility model, through the threaded connection structure of the sleeve and the extension rod, can realize flexible adjustment of the grouting pipe length. When the construction depth increases, the extension rod can be quickly assembled, improving applicability and reducing construction inconvenience caused by insufficient length. The threaded connection of the sleeve and the extension rod facilitates quick assembly and disassembly, reducing manual operation time and complexity.

[0014] 3. The sealing pipe of this utility model can be removed and reused after grouting is completed. The sleeve and extension rod can also be disassembled and used for other grouting pipes, avoiding the high cost problem of one-time sealing structure and greatly reducing the consumption and cost of construction materials.

[0025] In this embodiment, specifically: the sleeve 3 is connected to an extension rod 4, one end of the extension rod 4 is provided with a second external thread 401 that engages with the internal thread 301, and the end of the extension rod 4 away from the second external thread 401 is provided with a third external thread 402.

[0026] In this embodiment, specifically: the outer diameter of the connecting ring 203 is the same as the outer diameter of the grouting pipe body 1; the size of the first grouting hole 101 is the same as the size of the through hole 201; the insert block 204 and the slot 205 are respectively provided in four sets and evenly distributed; the through hole 201 is located directly below the insert block 204; the first grouting hole 101 is located directly below the slot 205; the first grouting hole 101 and the end cap 202 are respectively provided in two sets; the first grouting hole 101 and the through hole 201 are vertically and evenly distributed.

[0027] In this embodiment, specifically, the outer diameter of the sleeve 3 is the same as the outer diameter of the grouting pipe body 1.

[0028] In this embodiment, specifically: the outer diameter of the extension rod 4 is the same as the outer diameter of the grouting pipe body 1, the second external thread 401 and the third external thread 402 have the same dimensions, and the height of the sleeve 3 is the sum of the heights of the first external thread 303 and the second external thread 401.

[0029] Working principle: During grouting, the grouting pipe body 1 is inserted into the pre-constructed pipe. At the time of insertion, the sealing pipe 2 is inserted into the grouting pipe body 1, so that the connecting ring 203 fits against the top of the grouting pipe body 1, and the insert block 204 is inserted into the slot 205.
