Description

Technical Field

[0001] This utility model relates to the field of chemical grouting technology for lock structure joints, specifically an expansion-fixed chemical grouting pipe device for lock structure joints. Background Technology

[0002] In the chemical grouting construction of lock structure joints, an important construction step is to drill holes in the surface of the leaking structural joint and then embed chemical grouting pipes. Construction workers drill holes along the joint surface according to the on-site leakage situation and install several or dozens of grouting pipes. Then, chemical sealing material is pressed into the structural joint through the grouting pipes to block the leakage channel and achieve the purpose of stopping the water seepage.

[0003] The announcement number is CN220813860U, which discloses "a chemical grouting pipe device for expansion-fixed lock structure joints, including a grouting pipe, a sealing expansion pipe, and a jacking pipe; an expansion cone is fixed to the outer wall of the grouting pipe, and a pipe thread is provided on the grouting pipe on one side of the small diameter end of the expansion cone; the sealing expansion pipe is sleeved on the grouting pipe and expands through the expansion cone; the jacking pipe is threaded to the pipe body and pushes the sealing expansion pipe toward the expansion cone";

[0004] There are still some drawbacks in its use. The grouting pipe is fixed by expanding the sealing expansion tube outward to press against the inner wall of the grouting hole. When turning the sealing expansion tube, the grouting pipe needs to be kept still so that the sealing expansion tube can rotate. The expansion of the sealing expansion tube requires a large force, so the force required to keep the grouting pipe fixed is also large. It is not convenient for a single person to operate. In addition, the grouting pipe is a round pipe, which is not easy to fix by manpower. Tools are needed to clamp the grouting pipe to keep it fixed. The process of fixing the grouting pipe is quite cumbersome. Utility Model Content

[0005] The purpose of this invention is to provide an expansion-fixed chemical grouting pipe device for lock structure joints to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An expansion-fixed chemical grouting pipe device for lock structure joints includes:

[0008] A support assembly, the support assembly including a bottom ring, on one side surface of the bottom ring being fixedly installed with multiple vertical rods at equal angles;

[0009] A grouting assembly is movably inserted between multiple vertical rods. The grouting assembly includes a grouting pipe movably inserted between multiple vertical rods. Multiple connecting plates are fixedly installed at equal angles on the outer surface of the grouting pipe. Multiple connecting seats are fixedly installed at equal intervals on one side surface of the connecting plates. A pointed conical top rod is rotatably connected inside the connecting seat.

[0010] The sealing component is fixedly installed inside one end of the grouting pipe.

[0011] Furthermore, multiple top blocks are fixedly installed at equal intervals on one side surface of the vertical rod, and a stop bar is fixedly installed on one side surface of each top block.

[0012] Furthermore, a lever is obliquely fixedly installed at one end of the pointed cone rod that passes through the connecting seat.

[0013] Furthermore, a limiting block is fixedly installed on one end surface of the vertical rod, and a movable groove is formed on one side surface of the limiting block.

[0014] Preferably, multiple threaded sleeves are fixedly installed at an equal angle at one end of the outer surface of the grouting pipe, and bolts are screwed into the threaded sleeves. The bolts pass through the threaded sleeves and are movably connected to the movable grooves.

[0015] Furthermore, the sealing assembly includes:

[0016] A plugging ring is fixedly installed at one end of the inner surface of the grouting pipe;

[0017] The blocking plate is movably inserted into the inside of the blocking ring;

[0018] The top rod is fixedly installed on one side of the end plate.

[0019] Preferably, a fixing frame is fixedly installed at one end of the inner surface of the grouting pipe, the top rod passes through the fixing frame and is slidably connected to the fixing frame, and limit rings are fixedly installed on the outer surface and one end of the top rod.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. By inserting the vertical rod and bottom ring into the pre-drilled grouting hole, and then aligning the connecting plate with the gap between the limiting blocks, the support assembly is inserted into the grouting hole. Loose concrete blocks on the inner wall of the grouting hole are cleared, allowing the grouting pipe to be smoothly inserted into the grouting hole. The grouting pipe is then inserted between the vertical rods, and the grouting pipe is rotated. The bolts are tightened, and the distance between the threaded sleeve and the limiting block is adjusted and fixed to improve the stability of the grouting pipe during fixing. The grouting pipe is pulled, causing the top block to push the pointed cone rod to rotate, so that the tip of the pointed cone rod abuts against the inner wall of the grouting hole, thus fixing the grouting pipe. This method facilitates single-person operation of the grouting pipe and replaces tools for clamping and fixing the grouting pipe, making the fixing process of the grouting pipe simpler.

[0022] 2. During grouting, the concrete slurry impacts the blocking plate, causing the top rod to slide inside the fixed frame, opening the middle of the blocking ring, and allowing the concrete to be injected into the gap through the grouting pipe. After grouting is completed, the top rod is pulled upwards to block the blocking ring with the blocking plate, preventing the concrete from overflowing from the top of the grouting pipe under the pressure of the gap.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-5 In this embodiment of the utility model, an expansion-fixed chemical grouting pipe device for a lock structure includes a support component 1. The support component 1 includes a bottom ring 101. Multiple vertical rods 102 are fixedly installed at equal angles on one side surface of the bottom ring 101. A grouting component 2 is movably inserted between the multiple vertical rods 102. The grouting component 2 includes a grouting pipe 201 movably inserted between the multiple vertical rods 102. Multiple connecting plates 202 are fixedly installed at equal angles on the outer surface of the grouting pipe 201. Multiple connecting seats 203 are fixedly installed at equal intervals on one side surface of the connecting plates 202. A pointed conical top rod 204 is rotatably connected inside the connecting seat 203. A sealing component 3 is fixedly installed at one end inside the grouting pipe 201.

[0031] Specifically, by first inserting the vertical rod 102 into the grouting hole, a smooth channel is created for the insertion of the grouting pipe 201, and the grouting pipe 201 is fixed by the support component 1.

[0032] Example 1

[0033] like Figure 1-3 As shown, in this embodiment, a plurality of top blocks 103 are fixedly installed at equal intervals on one side surface of the vertical rod 102, and a stop rod 104 is fixedly installed on one side surface of the top block 103; a lever 205 is fixedly installed at one end of the pointed cone top rod 204 through the connecting seat 203; a limit block 105 is fixedly installed on one end surface of the vertical rod 102, and a movable groove 106 is opened on one side surface of the limit block 105.

[0034] In this embodiment, the vertical rod 102 and the bottom ring 101 are inserted into the pre-drilled grouting hole. Then, the connecting plate 202 is aligned with the gap between the limiting blocks 105, and the grouting pipe 201 is inserted between the vertical rods 102. At this time, the abutment rod 104 is in contact with the inner wall of the grouting hole. Then, the grouting pipe 201 is rotated, so that the connecting plate 202 abuts against the vertical rod 102. Pulling the grouting pipe 201 causes the top block 103 to push the lever 205, which in turn drives the pointed cone top rod 204 to rotate inside the connecting seat 203, causing the pointed cone to... The tip of the push rod 204 abuts against the inner wall of the grouting hole, fixing the grouting pipe 201. Then, the support component 1 is inserted into the grouting hole to clear the loose concrete blocks on the inner wall of the grouting hole, allowing the grouting pipe 201 to be smoothly inserted into the grouting hole. By lifting the grouting pipe 201, multiple pointed push rods 204 abut against the inner wall of the grouting hole, fixing the grouting pipe 201. This makes it easy for a single person to operate the grouting pipe 201, and also replaces tools to clamp and fix the grouting pipe 201, making the fixing process of the grouting pipe 201 simpler.

[0035] like Figure 4 As shown, in this embodiment, multiple threaded sleeves 206 are fixedly installed at an equal angle at one end of the outer surface of the grouting pipe 201. Bolts 207 are screwed into the threaded sleeves 206 and are movably connected to the movable groove 106 through the threaded sleeves 206.

[0036] In practice, the bolt 207 is tightened to press against the movable groove 106, and the distance between the threaded sleeve 206 and the limiting block 105 is adjusted and fixed to improve the stability of the grouting pipe 201 when it is fixed.

[0037] Example 2

[0038] Based on Example 1, in order to compensate for the problem that concrete easily overflows from the top of the grouting pipe 201 under pressure.

[0039] like Figure 4As shown, in this embodiment, the sealing assembly 3 includes: a blocking ring 301 fixedly installed at one end of the inner surface of the grouting pipe 201; a blocking plate 303 movably inserted into the blocking ring 301; and a top rod 304 fixedly installed on one side surface of the blocking plate 303. A fixing frame 302 is fixedly installed at one end of the inner surface of the grouting pipe 201, and the top rod 304 passes through the fixing frame 302 and is slidably connected to the fixing frame 302. Limiting rings 305 are fixedly installed on the outer surface and one end of the top rod 304.

[0040] In practice, during grouting, the concrete slurry impacts the blocking plate 303, causing the top rod 304 to slide inside the fixing frame 302, opening the middle of the blocking ring 301, allowing the concrete to be injected into the gap through the grouting pipe 201. After grouting is completed, the top rod 304 is pulled upwards, causing the blocking plate 303 to block the blocking ring 301, preventing the concrete from overflowing from the upper end of the grouting pipe 201 under the pressure of the gap.
