Technical Field
[0001] This utility model relates to the field of dewatering well technology, specifically to a reusable all-steel sleeve dewatering well structure. Background Technology
[0002] In underground engineering construction, dewatering wells are key equipment for lowering the groundwater level and ensuring the dryness of the foundation pit.
[0003] Traditional dewatering wells are constructed by inserting multiple all-steel sleeves into the borehole and then splicing them together. The all-steel sleeves can be reused. However, when splicing all-steel sleeves, the process mostly involves the use of flanges and bolts. This requires manual alignment of the flange bolt holes one by one, followed by tightening the bolts one by one to connect the two all-steel sleeves together. This makes the connection process cumbersome and time-consuming, thus reducing the splicing efficiency between all-steel sleeves. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a reusable all-steel sleeve dewatering well structure, comprising a cylinder body, and further comprising a water filtering assembly disposed on the lower exterior of the cylinder body; a splicing assembly disposed at the end of the cylinder body; and two sets of support assemblies disposed on the upper exterior of the cylinder body; wherein, the water in the borehole is filtered by the water filtering assembly, the two cylinder bodies are quickly spliced by the splicing assembly, and the cylinder body is supported by the support assemblies.
[0006] Preferably, the splicing assembly includes a first clamp, which is attached to the lower outer wall of the cylinder; a second clamp is rotatably connected to the outer wall of the first clamp via a pin, and its interior is attached to the lower outer wall of the cylinder; two annular platforms are fixed to the inner walls of the first clamp and the second clamp, respectively; two studs are rotatably connected to the ends of the second clamp via pins; two nuts are threaded to the outer walls of the two studs, and their outer walls are attached to the outer wall of the first clamp; limiting portions are respectively disposed outside the first clamp and the second clamp; wherein, driven by the first clamp and the second clamp, the annular platforms are both attached to the ends and outer walls of the cylinder, and the cylinders are spliced together by the cooperation of the studs and nuts.
[0007] Preferably, the limiting part includes an insertion hole, which is formed on the outer wall of the cylinder; the insertion block is fixed to the inner wall of the first clamp and the inner wall of the second clamp respectively, and the outer wall is inserted into the inner wall of the insertion hole; wherein, the first clamp and the second clamp are limited by the cooperation of the insertion block and the insertion hole.
[0008] Preferably, the support assembly includes a connecting seat fixed to the upper outer wall of the cylinder; a connecting column fixed to the side wall of the connecting seat; a support plate fixed to the end of the connecting column; and a protrusion fixed to the side wall of the support plate. The support plate is fixed to the cylinder by the connecting seat and the connecting column, and the cylinder is supported by the support plate and the protrusion.
[0009] Preferably, the water filtration assembly includes a water filtration hole, which is opened on the lower part of the outer wall of the cylinder and located above the first clamp; a filter screen is fixed to the outer wall of the cylinder on the side near the water filtration hole; wherein, the water in the borehole is filtered through the water filtration hole and the filter screen.

[0011] Beneficial effects
[0012] This invention provides a reusable all-steel sleeve dewatering well structure. It offers the following advantages: This reusable all-steel sleeve dewatering well structure, through the cooperation of a first clamp, a second clamp, an annular platform, a stud, a nut, and a limiting part, enables rapid assembly of the sleeve body. This solves the problem of cumbersome and time-consuming connection processes during the assembly of all-steel sleeves, thus reducing the efficiency of splicing between all-steel sleeves.
[0013] By combining the connecting seat, connecting column, support plate and protrusion, the sinking or displacement of the cylinder is prevented. This solves the problem that when traditional dewatering wells rely on sand and gravel filter material for support, in complex strata such as loose sand or fluid clay layers, the traditional filter material is easily washed away by groundwater, and the support effect weakens over time, eventually causing the cylinder to tilt or sink.

[0016] 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.
[0017] The splicing of all-steel sleeves is complicated and time-consuming, which reduces the splicing efficiency between all-steel sleeves.
[0018] In view of this, the present invention provides a reusable all-steel sleeve dewatering well structure. Through the cooperation of the first clamp, the second clamp, the annular platform, the stud, the nut and the limiting part, the cylinder body can be quickly spliced. This solves the problem that the connection process is cumbersome and time-consuming when splicing all-steel sleeves, thereby reducing the splicing efficiency between all-steel sleeves.
[0019] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.
[0020] Example 1: By Figure 1-4 It is known that a reusable all-steel sleeve dewatering well structure includes a cylinder 1. The reusable all-steel sleeve dewatering well structure also includes a water filtering component 2, a splicing component 3, and a support component 4. The water filtering component 2 is located on the lower exterior of the cylinder 1; the splicing component 3 is located at the end of the cylinder 1; and two sets of support components 4 are provided, both located on the upper exterior of the cylinder 1. The water filtering component 2 filters the water in the borehole, the splicing component 3 quickly splices the two cylinders 1, and the support component 4 supports the cylinder 1. In the specific implementation process, it is worth noting that the cylinder 1 is made of Q355 high-strength steel to ensure structural strength and resistance to deformation. The workers lower multiple all-steel sleeves into the borehole and then splice the multiple all-steel sleeves to form a dewatering well. The all-steel sleeves can be reused. The water in the borehole is filtered by the water filter assembly 2. The two cylinders 1 are quickly spliced by the splicing assembly 3. The cylinder 1 is supported by the support assembly 4.
[0021] Example 2: From Figure 1-4 It can be seen that the splicing component 3 includes a first clamp 31, a second clamp 32, an annular platform 33, studs 34, nuts 35, and a limiting part 36. The first clamp 31 is attached to the lower outer wall of the cylinder 1; the second clamp 32 is rotatably connected to the outer wall of the first clamp 31 via a pin, and its interior is attached to the lower outer wall of the cylinder 1; there are two annular platforms 33, which are respectively fixed to the inner walls of the first clamp 31 and the second clamp 32; there are two studs 34, which are respectively fixed to the inner walls of the first clamp 31 and the second clamp 32 via pins. The pin is rotatably connected to the end of the second clamp 32; there are two nuts 35, which are threaded to the outer walls of the two studs 34 respectively, and the outer walls are in contact with the outer wall of the first clamp 31; the limiting parts 36 are respectively provided outside the first clamp 31 and outside the second clamp 32; wherein, under the drive of the first clamp 31 and the second clamp 32, the annular platform 33 is in contact with the end and outer wall of the cylinder 1, and the cylinder 1 is spliced together by the cooperation of the studs 34 and nuts 35; In the specific implementation process, it is worth noting that the first clamp 31 and the second clamp 32 are semi-circular steel clamps, the annular platform 33 is integrally formed with the first clamp 31 and the second clamp 32, the stud 34 is a high-strength steel stud, and the nut 35 is a self-locking nut. The first clamp 31, the second clamp 32 and the annular platform 33 are made of Q355 steel, and the stud 34 and the nut 35 are made of No. 45 steel with heat treatment to enhance strength and wear resistance. When splicing the two cylinders 1, the operator moves the first clamp 31 and the second clamp 32 to fit them against the ends of the two cylinders 1. At the same time, the first clamp 31 and the second clamp 32 drive the annular platform 33 to move and contact the end of the cylinder 1. Then the second clamp 32 is closed. Finally, the operator rotates the stud 34 to enter the outer wall of the first clamp 31 and tightens the nut 35. The axial force of the stud 34 and the nut 35 tightens the first clamp 31 and the second clamp 32. The annular platform 33 presses against the end of the cylinder 1, thus completing the splicing between the two cylinders 1. When disassembling, the operator rotates the nut 35 off the stud 34 to release the fixation of the first clamp 31 and the second clamp 32, which facilitates the recycling and reuse of the cylinder 1 and enables rapid splicing of the cylinder 1. Furthermore, the limiting part 36 includes an insertion block 361 and an insertion hole 362, the insertion hole 362 being formed on the outer wall of the cylinder 1; the insertion block 361 is respectively fixed to the inner wall of the first clamp 31 and the inner wall of the second clamp 32, and its outer wall is inserted into the inner wall of the insertion hole 362; wherein, the first clamp 31 and the second clamp 32 are limited by the cooperation of the insertion block 361 and the insertion hole 362; In the specific implementation process, it is worth noting that the material of the insert block 361 is the same as that of the first clamp 31. When the first clamp 31 and the second clamp 32 are attached to the cylinder 1, the first clamp 31 and the second clamp 32 drive the insert block 361 to move and insert the insert block 361 into the insertion hole 362, thereby limiting the first clamp 31 and the second clamp 32 and preventing them from rotating. Furthermore, the support assembly 4 includes a connecting seat 41, a connecting column 42, a support plate 43, and a protrusion 44. The connecting seat 41 is fixed to the upper part of the outer wall of the cylinder 1; the connecting column 42 is fixed to the side wall of the connecting seat 41; the support plate 43 is fixed to the end of the connecting column 42; and the protrusion 44 is fixed to the side wall of the support plate 43. The support plate 43 is fixed to the cylinder 1 by the connecting seat 41 and the connecting column 42, and the cylinder 1 is supported by the support plate 43 and the protrusion 44. In the specific implementation process, it is worth noting that the connecting seat 41 is welded to the outer wall of the cylinder 1, the connecting column 42 is welded to the connecting seat 41 as a whole, the support plate 43 is an arc-shaped steel plate welded to the connecting column 42, the connecting seat 41 and the connecting column 42 are made of Q355 steel, and the support plate 43 and the protrusion 44 are made of wear-resistant steel. After the cylinder 1 is lowered into the borehole, the support plate 43 and the protrusions 44 on its surface contact the borehole wall. The weight of the cylinder 1 is transferred to the borehole wall through the connecting seat 41 and the connecting column 42, preventing the cylinder 1 from sinking or shifting. At the same time, the two sets of support components 4 are symmetrically distributed around the circumference, making the cylinder 1 more uniformly stressed, adaptable to loose sand layers, clay layers and various geological conditions, and ensuring the long-term stability of the dewatering well. Furthermore, the water filtration assembly 2 includes a water filtration hole 21 and a filter screen 22. The water filtration hole 21 is opened on the lower part of the outer wall of the cylinder 1 and is located above the first clamp 31. The filter screen 22 is fixed to the outer wall of the cylinder 1 on the side close to the water filtration hole 21. The water in the borehole is filtered through the water filtration hole 21 and the filter screen 22. In the specific implementation process, it is worth noting that the filter holes 21 are circumferentially evenly distributed conical holes (inner hole diameter 15mm, outer hole diameter 10mm), arranged in a plum blossom pattern, which not only expands the water permeability area, but also uses the "larger inside and smaller outside" structure to prevent the filter screen from clogging. The filter screen 22 is a double-layer composite structure. The inner layer is a 304 stainless steel fine mesh (hole diameter 0.1-0.3mm) to achieve fine sand filtration, and the outer layer is a galvanized steel wire mesh (hole diameter 1-2mm) to play the role of preliminary filtration and protection of the inner mesh. The double mesh is tightly fixed to the outer wall of the cylinder 1 by stainless steel cable ties, and completely fits the area of the filter holes 21 to achieve filtration of water in the borehole. Furthermore, sealing rings 5 are fixed to the outer walls of both annular platforms 33, and the outer walls of the sealing rings 5 are attached to the ends of the cylinder 1. In the specific implementation process, it is worth noting that the sealing ring 5 is made of nitrile rubber ring, which is bonded to the outer wall of the annular platform 33 with a thickness of 3-5mm. A reliable seal is achieved when the compression is 2-3mm. When splicing, the annular platform 33 presses against the end of the cylinder 1, and the sealing ring 5 is squeezed and deformed to fill the gap, preventing groundwater from seeping into the interior of the cylinder 1 from the splice, ensuring the precipitation efficiency and avoiding the loss of filter material.
