[0028] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0029] See also Figures 1 to 3The detachable well pipe provided by the embodiment of the utility model includes a well pipe body 10 and a support assembly. The well pipe body 10 includes a plurality of wellbores 11, which are stacked in sequence from top to bottom, and two adjacent wellbores 11 are detachably connected; the wellbores 11 include a plurality of arc segments 111, which are sequentially connected along the circumference of the wellbores 11, and each arc segment 111 is formed with connecting ends on both sides along the horizontal direction, and two adjacent connecting ends are detachably connected; the support assembly is arranged on the outer periphery of the wellbores 11 located at the bottom layer, one end of the support assembly is connected to the wellbores 11, and another end of the support assembly is in contact with the ground, and the support assembly is inclined from top to bottom in a direction away from the wellbores 11.

[0030] Generally speaking, the well pipe body 10 is inserted into the foundation pit slope along the vertical direction. For the convenience of description in conjunction with the drawings, the directions below are described in accordance with the directions shown in the drawings, but are not limited thereto.

[0031] Since the well pipe is composed of a plurality of detachably connected well shafts 11, the operator can easily remove the part of the well shaft 11 that needs to be removed in sections without the need for overall removal or manual breaking, thereby improving construction efficiency. The disassembly process is simple and easy to operate, reducing the construction risks caused by manual breaking or overall disassembly of the well pipe, such as the risk of injury from debris and damage to the dewatering pump. The multiple detachable uses of the well shaft 11 reduce the demand for well pipe materials and save costs. In addition, the detachable design of the well shaft 11 reduces the risk of damage to the well shaft 11 due to careless disassembly of the well pipe, extends the service life of the well pipe, and can flexibly adjust the height of the well pipe according to actual needs to adapt to the dewatering needs of different foundation pit depths. In addition, by arranging a support assembly at the bottom of the well pipe body 10, it plays a supporting effect on the well pipe body 10, preventing the well pipe body 10 from tipping over, and improving the safety and stability of the installation process.

[0032] Regarding the support assembly, the support assembly package is made of steel plates, and the support assembly is arranged around the outer periphery of the bottom shaft 11. The support assembly is inclined from top to bottom away from the shaft 11, thereby increasing the bottom area of ​​the support assembly and having better stability.

[0033] Regarding the shaft 11, a limiting block 114 is provided at one end of the shaft 11, and a limiting groove is provided at the other end of the shaft 11, and the limiting blocks 114 of two adjacent shafts 11 can be snapped into the limiting groove. Through the cooperation of the limiting block 114 and the limiting groove, the position of the shaft 11 can be effectively fixed to prevent dislocation or falling off during the construction process. In addition, the design of the limiting block 114 and the limiting groove makes the disassembly and installation of the shaft 11 more convenient, reduces the disassembly and installation time and difficulty of the operator, and has a high disassembly and installation efficiency. In addition, in this embodiment, the height of each shaft 11 is set to 50 mm. In other embodiments, it can be adjusted according to the actual working conditions, and there is no limitation here.

[0034] Specifically, the limit block 114 extends in a trapezoidal shape, and the cross-sectional area of ​​the limit block 114 gradually decreases in the direction away from the wellbore 11, so that the connection between the limit block 114 and the limit groove is tighter, the stability of the wellbore 11 is enhanced, and the bearing capacity of the overall well pipe is improved. In addition, the cross-sectional area of ​​the insertion end of the limit block 114 is reduced, which is convenient for the operator to align and also convenient for inserting the limit block 114 into the limit groove, thereby improving the installation efficiency. In other embodiments, the limit block 114 can also be set to a truncated cone shape, a rectangular parallelepiped shape, etc., which is not limited here. It is understandable that the shape of the limit groove needs to be adaptively adjusted according to the shape of the limit block 114 so that the limit block 114 and the limit groove can be engaged with each other.

[0035] More specifically, a plurality of limit blocks 114 are provided, and the plurality of limit blocks 114 are arranged at intervals along the circumference of the wellbore 11, and a limit groove is provided at the other end of the wellbore 11 corresponding to each limit block 114. The plurality of limit blocks 114 are arranged along the circumference, so that the force on the wellbore 11 is more uniform during disassembly, reducing the risk of damage caused by excessive local force. In addition, the cooperation between the plurality of limit blocks 114 and the limit groove makes the connection of the wellbore 11 more secure, and enhances the stability and bearing capacity of the overall well pipe.

[0036] In other embodiments, a connecting plate may be provided at the end of the wellbore 11, the connecting plate extends along the circumference of the wellbore 11 and is fixedly connected to the outer surface of the wellbore 11, and a connecting hole is provided on the connecting plate, and the connecting holes on the connecting plates of two adjacent wellbores 11 are arranged one by one, and the locking bolts may be sequentially passed through the two connecting holes and locked, thereby realizing the connection process of the two adjacent wellbores 11. A plurality of connecting holes may be provided on the connecting plate, and the plurality of connecting holes are arranged at intervals along the circumference of the connecting plate, and a corresponding locking bolt is provided for each connecting hole for locking, thereby improving the stability of the two wellbores 11 after installation.

[0037] In order to prevent the poor sealing of the connection between the two wellbores 11, which may cause the liquid in the wellbores 11 to leak, a sealing ring is provided at the connection between the two adjacent wellbores 11. The sealing ring forms an effective seal at the connection between the two adjacent wellbores 11, preventing the liquid from leaking at the connection, and ensuring the normal operation of the well pipe. Specifically, the sealing ring uses an existing rubber sealing ring, which is a commonly used device in the field. Its specific structure and working principle are not described here.

[0038] In order to facilitate the disassembly and transportation of the wellbore, the wellbore 11 is detachably connected by a plurality of arc segments 111 connected in sequence. Specifically, there are two arc segments 111, each arc segment 111 is semicircular, and the connecting ends of the two arc segments 111 can be correspondingly buckled and connected. The two arc segments 111 make the disassembly and assembly process relatively simple and improve the disassembly and assembly efficiency. The semicircular design of the arc segment 111 makes the connecting end more stable, which can effectively prevent the displacement or deformation of the wellbore 11 during use, and enhances the stability and carrying capacity of the wellbore 11. In other embodiments, the wellbore 11 can also be composed of three, four or other multiple arc segments 111, and in some cases, the wellbore 11 can also be set to a rectangular parallelepiped shape, which is not too limited here.

[0039] Specifically, one end of the arc segment 111 is provided with a mounting protrusion 112, and the other end of the arc segment 111 is provided with a mounting groove 113, and the mounting protrusions 112 and mounting grooves 113 of two adjacent arc segments 111 can be interlocked. The mounting protrusion 112 can be snapped into the mounting groove 113, effectively preventing the arc segment 111 from loosening or falling off during use. The coordination of the mounting protrusion 112 and the mounting groove 113 makes the disassembly and assembly process of the arc segment 111 easier, and facilitates the operator to perform the operation process of dismantling or installing the arc segment 111. In other embodiments, the two adjacent arc segments 111 can also be arranged to be bolted, snap-fitted, or latched, etc., which will not be described in detail here.

[0040] More specifically, the mounting groove 113 is configured as a dovetail groove, and the mounting protrusion 112 is configured as a dovetail-shaped protrusion adapted to the dovetail groove. The combination of the dovetail groove and the dovetail-shaped protrusion can improve the sealing of the connection, reduce the risk of liquid leakage, and improve the use effect of the wellbore 11. In addition, the dovetail groove and the dovetail-shaped protrusion cooperate with each other to have better stability, which can prevent the wellbore 11 from being vibrated during operation, causing the arc segment 111 to loosen, fall off, etc. The dovetail groove and the dovetail protrusion are existing structures in the art, and their working principles and specific structures are not repeated here. It is worth noting that due to the special structure of the dovetail groove, the arc segment 111 will be interfered when being disassembled and assembled in the horizontal direction. Therefore, when disassembling and assembling the arc segment 111, it is necessary to insert the dovetail protrusion into the dovetail groove from top to bottom along the height direction, so that the two are clamped.

[0041] In order to prevent the soil on the foundation pit slope from loosening after the well pipe body 10 is installed, causing the foundation pit slope to collapse and cause safety risks. The detachable well pipe also includes a reinforcement frame, which is arranged on the foundation pit slope and surrounds the outer periphery of the well pipe body 10, and concrete is poured in the reinforcement frame. The arrangement of the reinforcement frame and concrete can effectively protect the well pipe body 10, extend the service life of the well pipe, reduce the frequency of maintenance and replacement, enhance the stability of the foundation pit slope and reduce earthwork transportation, help maintain the overall stability and integrity of the foundation pit slope, and improve the quality and reliability of the project.

[0042] In addition, in order to facilitate the operator to calculate, adjust, install and remove the wellbore 11, scale lines are set on the outer wall of the wellbore 11, and the scale lines extend along the axial direction of the wellbore 11. The setting of the scale lines facilitates the operator to accurately calculate the depth and position of the wellbore 11, which can improve the operator's work accuracy, reduce human errors, and ensure that the installation and removal operations of the wellbore 11 are accurate. This saves operation time and improves work efficiency.

[0043] The specific steps of using the detachable well pipe provided by the embodiment of the utility model are as follows:

[0044] First, calculate the exposed height of the well pipe body 10 after excavation, calculate the number of required wells 11 according to the exposed height, and connect the bottom well 11 to the outlet pipe. Then buckle the two arc segments 111 to form a complete well 11, and connect multiple wells 11 in sequence in the vertical direction so that the limit block 114 of each well 11 is clamped in the corresponding limit groove. After the wells 11 are connected, fill the periphery of the well pipe body 10 with soil. After the foundation pit slope is formed, remove the wells 11 layer by layer according to the thickness of the foundation pit slope until the height of the well pipe body 10 is flush with the required foundation pit slope. After the wells 11 are removed to the required height, a reinforcement frame is installed around the well pipe body 10, and concrete is poured in the reinforcement frame to ensure the stability of the foundation pit slope, thereby completing the installation process of the well pipe body 10.
