[0029] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0030] See also Figure 1 and Figure 2The stratum shield equipment reinforcement device provided by the embodiment of the utility model includes a support body 10 and a reinforcement body 20, the support body 10 extends along a first straight line direction; the reinforcement body 20 is arranged in the support body 10, and the reinforcement body 20 includes a reinforcement wall 21 and a fastening member, the reinforcement wall 21 is coaxially arranged with the support body 10, and the reinforcement wall 21 is surrounded to form an accommodating space 13, and the shield equipment 100 can move along the first straight line direction in the accommodating space 13, and an installation space 12 is formed between the reinforcement wall 21 and the supported body 10, and the fastening member is arranged in the installation space 12, one end of the fastening member is connected to the outer wall of the reinforcement wall 21, and the other end of the fastening member is connected to the support body 10, and the fastening member can drive the reinforcement wall 21 to move in the direction close to the shield equipment 100.

[0031] The support body 10 provides a stable support structure, so that the entire reinforcement device has good structural stability in the pressurized water formation. The double-layer protection structure formed between the reinforcement body 20 and the support body 10 not only improves the overall strength of the device, but also effectively prevents the infiltration of groundwater, further enhancing the water-stopping effect of the shield equipment 100. The installation space 12 formed between the reinforcement wall 21 and the support body 10 and the setting of the fastening member enable the reinforcement wall 21 to move in the direction close to the shield equipment 100 as needed, ensuring that the shield equipment 100 can be tightly connected with the external structure when receiving. By adjusting the gap, the stability and water-stopping effect of the shield equipment 100 are enhanced, and the problem of loose packing is avoided. The fastening member not only fixes and reinforces the wall 21, but also drives the reinforcement wall 21 to move, so that the shield equipment 100 can work more stably in the pressurized water formation, improving the safety and efficiency of the construction. By coordinating the supporting body 10, the reinforcement wall 21 and the fastening members, and adjusting the posture of the reinforcement wall 21 by the fastening members, a tight connection between the shield equipment 100 and the external structure is ensured, thereby enhancing the water-stopping effect and stability of the device.

[0032] It is understandable that, generally speaking, the shield equipment 100 is cylindrical, so the accommodating space 13 is also set to be cylindrical, so as to match the shield equipment 100; and the inner diameter of the accommodating space 13 is slightly larger than the outer diameter of the shield equipment 100, so as to prevent the shield equipment 100 from getting stuck during the disassembly and assembly process. In other embodiments, the accommodating space 13 can also be set to be a rectangular parallelepiped, etc., and is adjusted according to the size and shape of the shield equipment 100, which is not limited here.

[0033] Generally speaking, the shield equipment 100 operates horizontally, and therefore, the first straight line direction is defined herein as a horizontal 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.

[0034] The support body 10 also includes two support walls 11, which are arranged at intervals along the first straight line direction, and the support walls 11 are in contact with the inner wall of the support body 10. The arrangement of the two support walls 11 provides additional structural support, further enhancing the stability of the entire device, so that it can more firmly resist the pressure of groundwater and the impact of the external environment in the confined water formation. In addition, the interval arrangement design of the two support walls 11 can effectively disperse and transmit the pressure from the formation and groundwater, so that the support body 10 can withstand a larger load, reduce the stress concentration on a single wall, and extend the service life of the device.

[0035] In addition, the cross-section of the support body 10 is circular, the cross-section of the reinforcement body 20 is also circular, and the radius of the support body 10 is greater than the radius of the reinforcement body 20. Both the support body 10 and the reinforcement body 20 are designed with a circular cross-section, so that the overall structure can distribute stress more evenly when subjected to external pressure, reduce stress concentration, and enhance the stability and durability of the overall structure. The circular cross-section has good mechanical properties, can more effectively withstand and disperse multi-directional pressures from the strata and groundwater, improve the force-bearing performance of the reinforcement device, and ensure the safe operation of the shield equipment 100 in complex strata. The radius of the support body 10 is greater than the radius of the reinforcement body 20, so that an installation space 12 is formed between the two for installing a fastening member.

[0036] Furthermore, a waterproof layer is provided on the outer wall of the reinforced wall 21, which can effectively block the penetration of groundwater, improve the overall waterproof performance of the device, and ensure the construction safety of the shield equipment 100 in the confined water stratum. The waterproof layer can protect the reinforced wall 21 from water erosion, reduce corrosion and wear, extend the service life of the equipment, and reduce maintenance and replacement costs. In this embodiment, the waterproof layer uses a polyethylene waterproof coating. In other embodiments, the waterproof layer can also use other materials such as rubber, which is not limited here.

[0037] In addition, a waterproof filling layer 24 is provided in the installation space 12, which can effectively prevent groundwater from penetrating into the interior of the reinforcement device, enhance the waterproof performance of the entire device, and ensure the construction safety of the shield equipment 100 in the pressurized water stratum. Moreover, the waterproof filling layer 24 can provide additional support and stabilization in the installation space 12, fill the gaps and irregular spaces that may exist, improve the overall structural stability and compactness of the reinforcement device, effectively prevent groundwater from eroding the surrounding strata, reduce stratum deformation and settlement, protect the stability of the construction area, and reduce engineering risks. In this embodiment, the waterproof filling layer 24 is made of clay, which has a low cost, is easy to obtain and has a high density, and can achieve a good waterproof effect. In other embodiments, the waterproof filling layer 24 can also be made of cement, etc., which is not limited here.

[0038] Regarding the material of the support body 10, in this embodiment, the support body 10 is made of concrete material. To provide high-strength and high-stability structural support, ensure the stability and reliability of the reinforcement device in the confined water stratum, and reduce deformation or damage caused by stratum pressure. Concrete material has excellent compressive resistance, can effectively withstand the huge pressure from groundwater and strata, prevent structural rupture or failure, and ensure the safe operation of the shield equipment 100 under complex geological conditions. In other embodiments, the support body 10 can also be made of steel structure, etc., which is not limited here.

[0039] Specifically, the reinforcement wall 21 is located between the two supporting walls 11, and the two ends of the reinforcement wall 21 are elastically connected to the two supporting walls 11 respectively. The elastic connection design enables the reinforcement wall 21 to move freely within a certain range under the push of the fastening member, thereby enhancing the flexibility and adaptability of the overall structure and being able to better cope with changes in stratum and groundwater pressure. In addition, the elastic connection can effectively absorb and alleviate the impact force caused by earthquakes or stratum movement, reduce damage to structural components and stress concentration, enhance the seismic resistance of the device, and ensure that it can still work safely and stably in an environment with complex geological conditions.

[0040] More specifically, flexible rubber 22 is provided at both ends of the reinforcement wall 21, and the flexible rubber 22 is connected to the supporting wall 11. The flexible rubber 22 can effectively block the gap between the shield equipment 100 and the external structure, further improve the water-stopping effect, prevent underground pressurized water from penetrating into the shield equipment 100, and ensure the smooth progress of the construction. The flexible rubber 22 has good elasticity and buffering properties, and can absorb and alleviate the impact force and vibration caused by changes in formation pressure or movement of the shield equipment 100, reduce damage to the reinforcement device and the shield equipment 100, and extend the service life of the equipment.

[0041] Regarding the abutting member, in this embodiment, the abutting member is an oil cylinder 23, which includes a driving part 231 and a telescopic rod 232. The telescopic end of the telescopic rod 232 abuts against the reinforced wall 21, and the driving part 231 can drive the telescopic rod 232 to expand and contract along its own axis, so that the adjustment of the reinforced wall 21 is more accurate, and can be fine-tuned according to actual needs to ensure that the shield equipment 100 is always in the best position during the receiving and reinforcement process. The oil cylinder 23 can make the reinforced wall 21 fit closely with the structure between the shield equipment 100 and the supporting body 10 through the precise adjustment of the telescopic rod 232, thereby increasing the stability of the overall device, effectively preventing the shield equipment 100 from deflecting or loosening during the working process, and ensuring the continuity and stability of the construction. The precise telescopic adjustment of the oil cylinder 23 makes the sealing between the reinforced wall 21 and the shield equipment 100 and the supporting body 10 stronger, effectively reducing the gap and leakage path, significantly improving the water-stopping effect of the device, and solving the problem of poor water-stopping effect of the shield equipment 100 in the confined water stratum. In other embodiments, the abutment member may also be an electric push handle, a cylinder, etc., which will not be described in detail here. It is understandable that the oil cylinder 23 is a common mechanical device in the art, and its working principle and specific structure will not be described in detail here.

[0042] Specifically, a shock-absorbing pad is provided on the telescopic end, which can effectively absorb and alleviate the impact force and vibration generated during the telescopic process of the oil cylinder 23, reduce the impact on the reinforced wall 21 and the overall structure, and extend the service life of the equipment. In this embodiment, the shock-absorbing pad is a rubber pad. In other embodiments, the shock-absorbing pad can also be a spring pad, etc., which is not limited here.

[0043] The above embodiments are only to illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above embodiments. Without departing from the spirit and scope of the present invention, the present invention may be subject to various changes and modifications, which are within the scope of the present invention.
