The adjustment system comprises a plurality of adjustment units arranged at intervals, which are composed of a support beam 2 under the steel pipe 1, a wedge-shaped pad 3 and a fixed bottom plate 4 assembled with the support beam 2. At least one reaction member 42 is formed on the fixed bottom plate 4 of each adjustment unit, and a receiving portion 43 for receiving the wedge-shaped pad 3 is provided on the reaction member 42, and a hydraulic expansion device 44 abutting against the wedge-shaped pad 3 is provided in the receiving portion 43, and the wedge-shaped pad 3 is adapted to the corresponding steel pipe 1 and provides support, and an infrared transmitter 5 and an adapted infrared receiver 6 are provided on the reaction members 42 of the adjustment units at both ends of the adjustment system, and a bidirectional infrared signal device 7 adapted to the infrared transmitter and infrared receiver is provided on the reaction members 42 of the adjustment unit located in the middle. Each section of the steel pipe 1 of the support body is combined into a whole through a flange 10 and fixed with bolts and nuts to provide lateral support for the foundation pit support structure. The present application sets an independent adjustment unit under each section of the steel pipe 1, and uses the wedge-shaped pad 3 of the adjustment unit to provide a stable upward support force to the steel pipe, thereby ensuring the stability of the horizontal support as a whole; the wedge-shaped pad 3 is accommodated in the receiving portion 43 of the reaction member 42 and is independently adjusted through the hydraulic telescopic device 44, thereby improving the overall stability of the system; an infrared transmitter 5 and an infrared receiver 6 are set on the reaction member 42 of the outermost adjustment unit, and an adaptive two-way infrared signal device is set on the middle reaction member 42, which can accurately judge the support repair result, is simple and reliable to operate, and has a low overall cost.

[0022] In one embodiment, the joist 2 is an H-shaped steel, and the fixed base plate 4 includes a base 40 and a clamping portion 41 formed by bending downward from both ends of the base 40, and the clamping portion 41 is engaged with the flange of the H-shaped steel. The reliability of the assembly of the two can be enhanced by the clamping portion 41 provided on the fixed base plate 4 being engaged with the flange of the joist 2. In order to ensure that the fixed base plate 4 does not move relative to the joist 2, in a preferred embodiment, the fixed base plate 4 is welded and fixed to the joist 2.

[0023] In the present application, the reaction member located on the supporting beam of the outermost adjustment unit has the same structural setting as the reaction member of the middle adjustment unit, the difference is that the reaction member of the outermost adjustment unit is used to support the outermost steel pipe, so one reaction member is set on the fixed bottom plate; the reaction member of the middle adjustment unit is used to support two adjacent steel pipes, so it is set as two reaction members to simplify the overall structure.

[0024] Specifically, the reaction member 42 is formed by extending upward from the base 40 of the corresponding fixed bottom plate 4, and the reaction member 42 includes a first limiting beam 420, a second limiting beam 421 arranged in parallel, and a connecting portion 422 connecting the ends of the first limiting beam 420 and the second limiting beam 421, the connecting portion 422 has the same outer end surface as the first limiting beam 420 and the second limiting beam 421, and the top surface of the connecting portion 422 is higher than the top surface of the first limiting beam 420 and the second limiting beam 421, and the first limiting beam 420, the second limiting beam 421 and the connecting portion 422 are surrounded to form the receiving portion 43. As a preferred embodiment, the reaction member 42 is integrally formed with the fixed bottom plate 4 to enhance the overall strength.

[0025] The hydraulic expansion and contraction device 44 is arranged at the connection part 422, and an axial force monitoring device 45 is assembled on the hydraulic expansion and contraction device 44. The support body is used to provide lateral support force to the support structure system in the foundation pit project, and the adjustment system is used to repair the horizontal deformation of the support body. By controlling the hydraulic expansion and contraction device 44, the wedge-shaped pad 3 is horizontally displaced in the receiving part 43, thereby driving the steel pipe support to displace together, so that the infrared transmitter 5 arranged on the reaction member 42 coincides with the axis of the infrared receiver 6. The infrared receiver 6 receives the signal of the infrared transmitter 5, indicating that the horizontal deformation of the steel pipe support is successfully repaired.

[0026] Specifically, the wedge-shaped pad 3 includes a sliding portion 30 and a supporting portion 33 extending vertically from the sliding portion 30. The sliding portion 30 is received in the receiving portion 43, and the supporting portion 33 has an arc portion 34, the radius corresponding to the arc portion 34 is the same as the radius of the steel pipe, and the arc portion 34 is welded to the corresponding steel pipe.

[0027] The sliding portion 30 includes a main body portion 31 and convex ribs 32 extending upward from both ends of the main body portion 31. The receiving portion 43 is provided with a groove 430 for receiving the convex rib 32. The convex rib 32 cooperates with the groove 430 to fix the vertical freedom of the wedge-shaped pad 3, thereby ensuring the overall safety of the support system.

[0028] Specifically, two reaction members 42 with the same structure are formed on the fixed bottom plate 4 located in the middle. The two reaction members 42 and the base 40 of the fixed bottom plate 4 form a receiving cavity 401, and the flange 10 connecting the adjacent steel pipes 1 is located in the receiving cavity 401. The wedge-shaped pads 3 assembled in the two reaction members 42 are respectively welded to the corresponding steel pipes 1. The fixed bottom plate 4 of the adjustment unit located in the middle is supported by two joists 2 arranged in parallel. The clamping parts 41 formed by the downward bending of the two ends of the fixed bottom plate 4 are respectively embedded with the flanges of the outer ends of the two joists 2. In order to enhance the reliability of the assembly of the two, the fixed bottom plate 4 is welded and fixed to the joists 2.

[0029] A bidirectional infrared signal device 7 is provided on the outer first limiting beams 420 of the two reaction force components 42. The bidirectional infrared signal device 7 coincides with the axis of the infrared transmitter and the infrared receiver to ensure accurate transmission / reception of infrared signals.

[0030] The infrared transmitter 5 is arranged on the first limit beam 420 of the reaction member 42 at one end of the adjustment system, and the infrared receiver 6 is arranged on the first limit beam 420 of the reaction member 42 at the other end of the adjustment system. When the support body is in a normal position, the axis of the infrared transmitter and the infrared receiver coincide. The two-way infrared information device receives the signal of the infrared transmitter and calibrates each other two by two, and the infrared receiver receives the final signal. That is, the infrared reflector 5 and the infrared receiver 6 are arranged on the reaction member corresponding to the outermost adjustment unit.

[0031] The hydraulic telescopic device in this application is a conventional device, which is composed of a hydraulic cylinder, a piston 441, an oil pipe, a control valve, an oil tank, a support structure 440 and a sensor. The piston 441 is arranged in the hydraulic cylinder, and the telescopic movement is realized by the input and output of the hydraulic oil. The two sides of the piston are respectively connected to the oil pipes, and the oil pipes lead to the control valve. The control valve is responsible for adjusting the flow direction of the oil, thereby controlling the movement of the piston. The hydraulic telescopic device is connected to the connection part of the reaction member through the support structure 440 of the hydraulic cylinder, and the support structure 440 provides stability and reaction force to withstand the load generated during the working process, and provide force transmission for repairing the horizontal deformation of the steel pipe support.

[0032] The hydraulic telescopic device is controlled by an electronic control system. The electronic control system uses sensors to monitor the position and axial force of the hydraulic cylinder in real time, and automatically adjusts the opening and closing of the control valve to achieve the extension and retraction of the hydraulic cylinder.

[0033] The axial force monitoring meter in this application is composed of a sensor, a housing, a cable and a data acquisition unit. The sensor is installed above the hydraulic telescopic device, the housing covers the sensor to protect it from external factors, and the data acquisition unit is connected to the sensor through a cable to receive and process the signal.

[0034] The working principle of the horizontal deformation repair device 100 of the steel pipe support of the present application is as follows: when the infrared receiver 6 on the reaction member cannot receive the signal emitted by the infrared transmitter 5, it means that the support body has undergone horizontal deformation, that is, the steel pipe may have undergone horizontal deformation due to uneven force or collision with external objects. After the alarm sounds, the on-site staff will immediately start the hydraulic expansion and contraction device of the corresponding reaction member according to the actual situation, and check the size of the applied force through the axial force monitoring device. Each reaction member has the function of independent adjustment, which can be started as needed according to the horizontal deformation of the steel pipe. The hydraulic expansion and contraction device can adjust the horizontal deformation of the steel pipe through hydraulic pressure. The wedge-shaped pad 3 is applied with force, and the wedge-shaped pad 3 is subjected to axial horizontal displacement due to the force. Since the steel pipe and the wedge-shaped pad 3 are welded as a whole, the steel pipe is horizontally displaced accordingly to offset the horizontal deformation previously generated until the infrared transmitter 5 on the reaction member coincides with the axis of the infrared receiver 6. That is, when the infrared receiver 6 receives the signal from the infrared transmitter 5, it indicates that the steel pipe support is successfully reset and the horizontal deformation has been repaired. The data on the axial force monitoring device 45 at this time is recorded, and then the hydraulic telescopic device 44 needs to continue to maintain the force state to maintain the safety and stability of the overall steel pipe support system and the fixed base plate 4 system.

In addition, various modifications can be made to the present application for specific circumstances or specific situations without departing from the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed, but should include all implementation methods falling within the scope of the claims of the present application.
