Description

Technical Field

[0001] The utility model relates to the technical field of grouting pipelines, in particular to a grouting device for water conservancy construction. Background Art

[0002] There are generally two ways to inject slurry into the hole in hydraulic grouting. The first is direct orifice grouting, which is suitable for shallow holes or simple working conditions. The operating steps are: the grouting pump is connected to the grouting plug (stop plug) at the orifice through a high-pressure hose, and the slurry is injected from the orifice and diffuses into the cracks through natural seepage or pressure. The second is in-hole pipe grouting, which is the mainstream method. The operating steps are: the pipe is pre-inserted into the bottom of the borehole, and the grouting pump directly grouts through the pipe. The slurry flows out from the bottom of the pipe or the side wall holes to fill the cracks.

[0003] The pipe types include disposable PVC flower pipes and reusable metal pipes, which are suitable for different strata.

[0004] When traditional metal pipes are grouted in sections from top to bottom, they need to work with grouting plugs. The cumbersome operation leads to low efficiency. In addition, the bottom tip of the metal pipe is integrated with the pipe body. During recovery and flushing, since the bottom is blocked, the cleaning water can only be discharged from the slurry outlet for cleaning. Some slurry will accumulate at the tip, which is difficult to clean, affecting subsequent reuse. Utility Model Content

[0005] In response to the above problems, the utility model provides a water conservancy construction grouting device, which is easy to operate and has a good sealing effect. The annular air inflation bag and the socket block are detachably connected, and the overall split detachable setting is further convenient for cleaning, prevents the slurry from solidifying, adhering or accumulating, and improves the recycling rate of the grouting pipe.

[0006] The technical solution adopted to solve the above technical problems is: a water conservancy construction grouting device, including a pipe body, a cone, a central axis, a sleeve block, an annular air inflation bag and a high-pressure rigid pipe, the pipe body is provided with multiple groups of slurry outlet holes at equal intervals, the lower end of the pipe body is opened, the cone is screwed to the lower end opening of the pipe body, the central axis is integrally connected to the upper side of the cone, the central axis is inserted in the pipe body, the sleeve block is slidably sleeved on the central axis, the sleeve block is set in a "T" shape, the annular air inflation bag is sleeved on the lower side of the sleeve block, the annular air inflation bag is detachably connected to the sleeve block, the lower end of the high-pressure rigid pipe is screwed to the annular air inflation bag, the high-pressure rigid pipe passes through the sleeve block, and the upper end of the high-pressure rigid pipe is slidingly sealed with the pipe body.

[0007] Furthermore, it also includes: the sleeve block is composed of two half blocks connected together; the upper end side wall of the tube body is integrally connected with the feed end pipe.

[0008] Furthermore, it also includes a bidirectional screw and two clamps. The bidirectional screw is rotatably connected to the upper side of the tube body, and the two clamps are respectively screwed on both sides of the bidirectional screw. The clamps are used to clamp the high-pressure rigid pipe. The high-pressure rigid pipe is provided with scale lines, and the scale lines match the spacing of the multiple groups of slurry outlet holes.

[0009] Furthermore, an anti-sticking pad is provided at the connection between the lower end of the tube body and the cone.

[0010] The beneficial effects of the present invention are as follows: the present invention arranges the grouting pipe in a split manner, and the lower end cone and the pipe body can be separated. When the grouting is completed and recovered, the cone and the pipe body can be disassembled and washed separately. When the grouting operation is carried out from top to bottom, the slurry will not contact the cone position through the cooperation of the annular air inflation bag, which is different from the traditional integrated grouting pipe, so as to prevent the slurry from accumulating and solidifying at the tip position. The split arrangement of the cone facilitates the removal of components such as the annular air inflation bag. By moving the high-pressure hard pipe downward, the sleeve block and the annular air inflation bag are driven downward, and the external air source is inflated through the high-pressure hard pipe. The annular air inflation bag expands to seal the slurry outlet hole. The grouting pump cooperates with the slurry discharge. The slurry is first ejected from the slurry outlet hole on the upper side. After the stratum structure gaps on the upper side are filled with slurry and the pressure value reaches the standard, the slurry outlet hole on the upper side no longer discharges slurry. The annular air inflation bag moves downward intermittently to grout the stratum structure gaps below, thereby realizing the top-down segmented grouting operation, which is easy to operate and has a good sealing effect. The annular air inflation bag is detachably connected to the socket block, and the overall split detachable setting is further convenient for cleaning, prevents the slurry from solidifying, adhering or accumulating, and improves the recycling rate of the grouting pipe.

[0016] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0017] like Figures 1-4 As shown, a water conservancy construction grouting device provided in this embodiment includes a pipe body 1, a cone 3, a central axis 4, a socket block 5, an annular air bag 6 and a high-pressure rigid pipe 7. The pipe body 1 is provided with multiple groups of slurry outlet holes 2 at equal intervals. The lower end of the pipe body 1 is opened, the cone 3 is screwed to the lower end opening of the pipe body 1, the central axis 4 is integrally connected to the upper side of the cone 3, the central axis 4 is inserted into the pipe body 1, the socket block 5 is slidably socketed on the central axis 4, the socket block 5 is "T"-shaped, the annular air bag 6 is socketed on the lower side of the socket block 5, the annular air bag 6 and the socket block 5 are detachably connected, the lower end of the high-pressure rigid pipe 7 is screwed to the annular air bag 6, the high-pressure rigid pipe 7 passes through the socket block 5, and the upper end of the high-pressure rigid pipe 7 is slidingly sealed with the pipe body 1.

[0018] In the above embodiment, the grouting pipe is set up in a split manner, and the lower end cone 3 and the pipe body 1 can be separated. When the grouting is completed and recovered, the cone 3 and the pipe body 1 can be disassembled and washed separately. When the grouting operation is carried out from top to bottom, the slurry will not contact the position of the cone 3 through the cooperation of the annular air bag 6, which is different from the traditional integrated grouting pipe, to prevent the slurry from accumulating and solidifying at the tip position, and the split setting of the cone 3 facilitates the removal of the annular air bag 6 and other components. By moving the high-pressure hard pipe 7 downward, the socket block 5 and the annular air bag 6 are driven downward, and the external air source is inflated through the high-pressure hard pipe 7 and introduced into the annular The air inflation bag 6 is inside, so that the air inflation bag expands to seal the slurry outlet hole 2. The grouting pump cooperates with the slurry discharge, and the slurry is first ejected from the slurry outlet hole 2 on the upper side. After the stratum structure gap on the upper side is filled with slurry and the pressure value reaches the standard, the slurry outlet hole 2 on the upper side no longer discharges slurry, and the annular air inflation bag 6 moves downward intermittently to grout the stratum structure gap below, thereby realizing the segmented grouting operation from top to bottom, which is easy to operate and has a good sealing effect. The annular air inflation bag 6 is detachably connected to the socket block 5, and the overall split detachable setting is further convenient for cleaning, prevents the slurry from solidifying, adhering or accumulating, and improves the recycling rate of the grouting pipe.

[0019] Specifically, it also includes: the socket block 5 is composed of two half blocks connected together; the upper end side wall of the tube body 1 is integrally connected with the feed end pipe 8.

[0020] In the above embodiment, the sleeve block 5 is configured as a split type, which is convenient for disassembly and cleaning from the central shaft 4 and prevents slurry from adhering to the sliding connection between the sleeve block 5 and the central shaft 4, causing jamming.

[0021] Specifically, it also includes a bidirectional screw rod 9 and two clamps 10. The bidirectional screw rod 9 is rotatably connected to the upper side of the tube body 1. The two clamps 10 are respectively screwed on both sides of the bidirectional screw rod 9. The clamps 10 are used to clamp the high-pressure rigid pipe 7. A scale line 11 is provided on the high-pressure rigid pipe 7. The scale line 11 matches the spacing of multiple groups of slurry outlet holes 2.

[0022] In the above embodiment, the downward movement of the high-pressure rigid tube 7 is clearly indicated by the scale line 11, so that the annular inflatable bag 6 can be aligned with the slurry outlet hole 2 for sealing. By rotating the bidirectional screw 9, the two clamps 10 are brought close to each other to clamp the high-pressure rigid tube 7.

[0023] Specifically, an anti-sticking pad 12 is provided at the connection between the lower end of the tube body 1 and the cone 3 .

[0024] In the above embodiments, the anti-sticking pad 12 is made of rubber.

[0025] The working principle of the utility model is as follows: during the grouting operation, the grouting pump is connected to the feed end pipe 8, and the grouting pump is operated to complete the grouting of the space above the annular air inflation bag 6. At this time, the gap in the stratum structure on the upper side is filled with slurry, and the pressure value reaches the standard. The slurry outlet hole 2 on the upper side no longer discharges slurry due to the pressure, and the two-way screw rod 9 is rotated to loosen the clamp 10. At this time, the external air source is exhausted, the annular air inflation bag 6 contracts, and the high-pressure hard pipe 7 is pushed down (the high-pressure hard pipe 7 is connected to the external air source through a hose), so that the socket block 5 and the annular air inflation bag 6 move down a distance, the external air source is inflated, and the high-pressure air enters the annular air inflation bag 6 to expand it, blocking the slurry outlet hole 2. The grouting pump is operated again to perform grouting operation on the position above the annular air inflation bag 6, and the operation is repeated to realize segmented grouting from top to bottom;

[0026] During cleaning, rotate and disassemble the cone 3, push the high-pressure hard tube 7 downward, so that the sleeve block 5 and the annular air bag 6 extend from the tube body 1, remove the annular air bag 6, and remove the sleeve block 5 to make it into two sub-blocks, and then clean the disassembled parts.

[0027] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
