[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-4 , the present invention discloses a dewatering Larssen steel sheet pile, including the body 1 of the Larssen steel sheet pile and a container 2. The container 2 is movably arranged at the bottom of the body 1 of the Larssen steel sheet pile. Fixed boxes 302 are fixedly arranged on both sides of the bottom of the body 1 of the Larssen steel sheet pile. Installation plates 3 are fixedly arranged on both sides of the container 2. A limit groove is formed on one side of the installation plate 3, and a limit block 301 is movably arranged inside the limit groove. One end of the limit block 301 penetrates through one side of the fixed box 302 and extends into the fixed box 302. One end of the limit block 301 is fixedly provided with a support plate 303;

[0024] A nut seat 304 is fixedly arranged at the bottom of the support plate 303. A lead screw 305 is movably arranged inside the inner wall of the nut seat 304. The connection relationship between the lead screw 305 and the nut seat 304 is a threaded connection. A worm gear 306 is fixedly arranged on the surface of the lead screw 305. A worm 307 is movably arranged on the back of the worm gear 306. One end of the worm 307 penetrates through the bottom of the inner wall of the fixed box 302 and extends to the bottom of the outer wall of the fixed box 302. One end of the worm 307 is fixedly provided with a rotating handle 308. A threaded ring 4 is fixedly arranged at the bottom of the fixed box 302. An installation cover 5 is movably arranged on the outside of the threaded ring 4.

[0025] Specifically, dewatering holes 101 are formed on the surface of the body 1 of the Larssen steel sheet pile. The dewatering holes 101 are evenly and equidistantly distributed. A filter body 201 is arranged inside the container 2.

[0026] In this implementation scheme, by providing precipitation holes 101, a container 2, and a filter body 201, water in the soil enters the container 2 through the precipitation holes 101. The container 2 is a sieve, and the filter body 201 is granular material. The filter body 201 can be selected from granular filter materials such as sand and gravel, and the filter body 201 can filter the water entering the container 2.

[0027] Specifically, a guide block 309 is fixedly provided at the bottom of the nut seat 304. One end of the guide block 309 is movably disposed in a chute at the bottom of the inner wall of the fixed box 302. The connection relationship between the fixed box 302 and the guide block 309 is a sliding connection.

[0028] In this implementation scheme, by providing the guide block 309, the guide block 307 will move along with the nut seat 304. The guide block 307 guides the nut seat 304, enabling the nut seat 304 to move stably.

[0029] Specifically, the connection relationship between the limit block 301 and the mounting plate 3 is a movable insertion connection.

[0030] In this implementation scheme, by providing the limit block 301, turning the handle 308 drives the worm 307 to rotate. The rotating worm 307 drives the worm gear 306 and the lead screw 305 to rotate. The rotating lead screw 305 makes the nut seat 304 and the limit block 301 move horizontally through the thread fit with the nut seat 304. When one end of the limit block 301 is inserted into the limit groove on the mounting plate 3, the mounting plate 3 can be limited and fixed.

[0031] Specifically, the connection relationship between the worm 307 and the worm gear 306 is a meshing connection.

[0032] In this implementation scheme, by providing the worm 307 and the worm gear 306, the worm 307 and the worm gear 306 have the characteristic of self-locking, thereby enhancing the stability of the lead screw 305.

[0033] Specifically, an external thread is provided on the outer wall of the threaded ring 4, and an internal thread is provided on the inner wall of the mounting cover 5. The connection relationship between the mounting cover 5 and the threaded ring 4 is a threaded connection.

[0034] In this implementation scheme, by providing the external thread and the internal thread, the mounting cover 5 can be installed or disassembled by rotating the mounting cover 5.

[0035] During use, water in the soil enters the container 2 through the precipitation holes 101. The container 2 is a sieve, and the filter body 201 is granular material. The filter body 201 can be selected from granular filter materials such as sand and gravel, and the filter body 201 can filter the water entering the container 2.

[0036] When disassembling the container 2, the mounting cover 5 is removed by rotating the mounting cover 5. Then, the worm 307 is rotated by turning the handle 308. The rotating worm 307 drives the worm gear 306 and the lead screw 305 to rotate. The rotating lead screw 305 makes the nut seat 304 and the limit block 301 move horizontally through the threaded engagement with the nut seat 304. When one end of the limit block 301 is removed from the limit groove on the mounting plate 3, the limit fixation of the mounting plate 3 can be released, and then the container 2 can be disassembled;

[0037] When installing the container 2, the container 2 is placed between the two fixed boxes 302. Then, the worm 307 is rotated by turning the handle 308. The rotating worm 307 drives the worm gear 306 and the lead screw 305 to rotate. The rotating lead screw 305 makes the nut seat 304 and the limit block 301 move horizontally through the threaded engagement with the nut seat 304. When one end of the limit block 301 is inserted into the limit groove on the mounting plate 3, the limit fixation of the mounting plate 3 can be achieved, and then the installation of the container 2 can be realized. Then, the mounting cover 5 is sleeved on the threaded ring 4, and the mounting cover 5 is installed on the fixed box 302 by rotating the mounting cover 5.

[0038] In summary, for this precipitation type Larssen steel sheet pile, by setting the limit block 301, nut seat 304, lead screw 305, worm gear 306, worm 307 and turning handle 308, the worm 307 is rotated by turning the handle 308. The rotating worm 307 drives the worm gear 306 and the lead screw 305 to rotate. The rotating lead screw 305 makes the nut seat 304 and the limit block 301 move horizontally through the threaded engagement with the nut seat 304. When one end of the limit block 301 is removed from the limit groove on the mounting plate 3, the limit fixation of the mounting plate 3 can be released, and then the container 2 can be disassembled, thus realizing the detachable function of the container 2 and facilitating the maintenance of the container 2. By setting the mounting cover 5, the mounting cover 5 covers the turning handle 308, making the turning handle 308 in a closed space, thus preventing the external force from accidentally touching the turning handle 308 and causing the worm 307 to rotate accidentally, thereby improving the stability of the movable insertion between the limit block 301 and the mounting plate 3.
