[0025] Pre-embedded plate 2 is used to cooperate fixed anchor rod 3 to fix baffle 1, pre-embedded plate 2 is inserted into the vicinity of leakage point by knocking knocking plate 23 from the periphery of foundation pit, if the depth of foundation pit is deeper, pre-embedded plate 2 can also be inserted into the pit dug, outer frame 21, tapered block 22 and knocking plate 23 are metal materials, ensure that the strength of pre-embedded plate 2 outside can meet the insertion into the soil, and the woodworking plate 24 arranged inside is convenient for fixed anchor rod 3 to penetrate woodworking plate 24, it needs to be explained that the double-block cement used in the present foundation pit leakage stopping has the ability of quick condensation and quick hardening, the whole leakage stopping operation time is short, so it is not necessary to consider the durability, and the woodworking plate 24 with low use cost can meet the demand;

[0026] The grouting assembly includes extension pipe 4 fixedly connected with baffle 1, drainage pipe 5 is arranged on the side, away from extension pipe 4, of baffle 1, drainage pipe 5 is arranged through baffle 1, one end of drainage pipe 5, close to baffle 1, is fixedly connected with threaded sleeve 6, threaded sleeve 6 is arranged inside drainage pipe 5, close to baffle 1, and a plurality of annular grooves 7 are formed in the inner wall of drainage pipe 5, close to threaded sleeve 6, one end of drainage pipe 5, away from baffle 1, is fixedly connected with limiting cone 8, and a plurality of barbs 9 are arranged on the side wall of limiting cone 8;

[0027] Based on the above design, when carrying out the plugging operation, the construction personnel first excavates the leakage point according to the process, can integrate multiple leakage points into a single large leakage point or trace the leakage point, and also excavate a space for grouting in the soil layer, then the user inserts the limiting cone 8 into the leakage point position, fixes it by using the barb 9, and guides the water outflowing from the leakage point out through the drainage pipe 5, then moves the baffle 1 to the area, fixes the baffle 1 near the excavated area by using the fixed anchor rod 3, then inserts the pipeline of the grouting equipment into the extension pipe 4 for grouting operation, waits for the grouting operation to be completed, pulls out the pipeline of the grouting equipment, according to the cement grouting amount and actual demand, can use the common rain cloth waste, cement woven bag and other objects in the production site to cover the extension pipe 4, and use the rope to tie, realize the plugging of the extension pipe 4;

[0028] After the grouting operation is completed, the drainage pipe 5 still maintains the state of outward drainage until the cement hardens and takes effect, then the drainage pipe 5 is plugged, and the cement is grouted into the drainage pipe 5, the position is completely plugged, and the whole leakage point plugging operation is finally completed;

[0029] It should be noted that the drainage pipe 5 includes a hard pipe section with a large outer diameter and a rigid material, and a soft pipe section with a metal ring embedded inside, the threaded sleeve 6 and the annular groove 7 are arranged in the hard pipe section, and the soft pipe section can be bent within a certain range, which is convenient for users to operate, and will not be crushed by the cement slurry pressure after grouting, causing the water to seep into the cement and affecting the hardening of the cement. On this basis, the threaded sleeve 6 is arranged to facilitate the user to connect the pipeline by using the threaded sleeve 6, and after the cement slurry hardens and takes effect, the external pipeline is taken out, and the user can further screw the plug into the threaded sleeve 6, and then grout the cement slurry into the place. The annular groove 7 can ensure that the cement block cannot be separated after the cement slurry solidifies into a cement block, and finally realize the plugging of the drainage pipe 5.

[0030] Further, the fixed anchor rod 3 includes an outer pipe 31, part of the outer wall of the outer pipe 31 is provided with external threads, the outer pipe 31 is threadedly connected with a blocking ring 32, and the end of the outer pipe 31 away from the blocking ring 32 is fixedly connected with a sharp cone 33. The sharp cone 33 blocks the opening of the outer pipe 31, and the end of the outer pipe 31 close to the sharp cone 33 is provided with a spiral blade 34. The side wall of the outer pipe 31 is provided with a strip-shaped groove, and the inner wall of the strip-shaped groove is rotatably connected with a blocking block 35. The outer pipe 31 is also slidably connected with a driving rod 36 for moving the blocking block 35;

[0031] In the design, the outer diameter of the blocking ring 32 is larger than the hole diameter of the mounting hole. During the fixing of the baffle 1, the construction personnel first inserts the embedded plate 2 into the soil near the leakage point, then aligns the marking with the embedded point position, adjusts the installation position of the baffle 1, ensures that the fixed anchor rod 3 can stably penetrate the embedded plate 2, sets the sharp cone 33 in cooperation with the spiral blade 34, which can improve the passability of the outer tube 31 when inserted into the soil. Because the soil and the embedded plate 2 can provide different force feedback during penetration, the construction personnel can ensure that the outer tube 31 has penetrated the embedded plate 2 according to the insertion depth of the outer tube 31. Then the construction personnel inserts the driving rod 36 into the outer tube 31. After the driving rod 36 abuts against the blocking piece 35, the driving rod 36 drives the blocking piece 35 to rotate, so that the blocking piece 35 pushes away the soil nearby and extends to the outside of the outer tube 31. At this time, the blocking piece 35 abuts against the embedded plate 2 (even if it is not tightly abutted, the construction personnel can adjust it by rotating the blocking ring 32, so that the fixed anchor rod 3 can better fix the baffle 1 even if it retreats).

[0032] Further, a plurality of grooves are formed in the wood board 24, and a steel cable 25 is arranged in the grooves. The two ends of the steel cable 25 are fixedly connected with the outer frame 21. This design is used for the case that the water pressure of the leakage point is large or the pit after excavation is large, and a large amount of cement slurry needs to be injected. The steel cable 25 can better hang the blocking piece 35, and the fixed anchor rod 3 can better fix the baffle 1. The wood board 24 ensures that the entire embedded plate 2 will not be displaced in the soil under stress.

[0033] The length of the steel cable 25 is greater than the width of the outer frame 21, and the steel cable 25 is arranged transversely. The length of the steel cable 25 is greater than the length of the outer frame 21. After the fixed anchor rod 3 directly abuts against the steel cable 25, the steel cable 25 can be pushed by the anchor rod, avoiding blocking the movement of the fixed anchor rod 3. It should be noted that based on this design, the outer tube 31 is also provided with an indicating rod perpendicular to the outer tube 31, which is used to facilitate the construction personnel to confirm the position of the strip-shaped groove, so that the blocking piece 35 can cooperate with the steel cable 25 after the driving rod 36 is inserted.

[0034] Further, the baffle 1 is fixedly connected with an inner lining plate 10 through bolts. The drainage pipe 5 is fixedly connected with the inner lining plate 10.

[0035] In this design, the inner lining plate 10 is used to facilitate the user to recycle part of the equipment in the leakage stopping device. The outer tube 31 and the drainage pipe 5 are covered by the cement slurry and cannot be taken out. The setting of the inner lining plate 10 can also take down the baffle 1, which is convenient for the user to recycle.

[0036] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
