In this application, an independent adjustment unit 2 is provided under each section of the steel pipe 1 of the support body, and the wedge-shaped pad 31 of the adjustment unit is used to provide vertical support force to the steel pipe 1 to ensure the support effect. When the steel pipe 1 is deformed, the adjustment support 34 is adjusted in the vertical direction to repair the longitudinal deformation of the steel pipe 1. At the same time, the support repair result is accurately judged by the calibration of the infrared transmitter 4 / receiver, and the operation is simple and reliable. The steel pipe support body is used to provide lateral support force for foundation pit support. Two adjacent steel pipes 1 are assembled and fixed by a flange 10, and the flange 10 is assembled by screws and nuts; the column mechanism 20 is used to provide force transmission guarantee for the support mechanism 30.

[0022] In one embodiment, the columns and the support beams 25 are both H-shaped steels, the wedge-shaped pads 31 are welded and fixed to the steel pipes 1, and triangular steel plates 11 are provided at both ends of the steel pipes 1.

The adjusting unit 2 located in the middle is provided with a support mechanism 30 on both side flanges of the first column 21 and the second column 22.

[0024] In order to ensure the reliability of the repair effect, a two-way infrared signal device 6 is provided at the bottom of the wedge-shaped pad 31 in the middle to receive / send the signal emitted by the infrared transmitter 4 set at one end, and transmit the infrared signal to the infrared receiver 5 set at the other end in turn according to the set position. The two-way infrared signal device 6 coincides with the axis of the infrared transmitter 4 and the infrared receiver 5 to ensure that the deformation can be accurately reflected and an alarm reminder can be issued when the support is in different positions; the axis of the infrared transmitter 4, the infrared receiver 5 and the two-way infrared signal device 6 are respectively parallel to the axis of each section of the steel pipe 1 support.

[0025] In one embodiment, the adjustment support 34 includes a push piece 35, a screw rod 36 and a fastening nut 37. The bottom of the wedge-shaped pad 31 is provided with a threaded hole 310 corresponding to the top of the screw rod 36. The screw rod 36 passes through the threaded hole 310 and is assembled with the wedge-shaped pad 31. The support beam 25 is provided with a base 38 for assembling the bottom end of the screw rod 36. The fastening nut 37 is assembled with the screw rod 36 and abuts against the push piece 35. The bottom end of the screw rod 36 is accommodated in the base 38. The base 38 is provided with a plurality of assembly holes. The corresponding second screws 39 are provided in the assembly holes to fix the base 38 to the flange of the drag beam. In the embodiment of the present application, in order to ensure the force balance of the wedge-shaped pad 31 when adjusting the fastening nut 37, two adjustment supports 34 are symmetrically arranged at the bottom of each wedge-shaped pad 31.

[0026] The fastening nut 37 includes a base 370 and a cylindrical assembly portion 372 extending vertically upward from the base 370. A cylindrical through hole 373 is provided at the center of the assembly portion 372. The through hole 373 axially penetrates the base 370 and an internal thread 374 is provided on the inner wall. An external thread 375 is provided on the outer wall of the assembly portion 372. The internal thread 374 is adapted to be assembled with the screw rod 36.

[0027] The push member 35 includes a push portion 350 that abuts against the wedge-shaped pad 31 and a limiting portion 351 connected to the push portion 350. Both the push portion 350 and the limiting portion 351 are cylindrical hollow structures, and the outer diameter of the push portion 350 is larger than the outer diameter of the limiting portion 351. A transition portion 352 connects the push portion 350 and the limiting portion 351. The inner wall of the limiting portion 351 is provided with a first internal thread 353 that is adapted to the external thread 375 of the assembling portion 372. The radial dimension of the push portion 350 is set to be larger than the radial dimension of the limiting portion 351, so as to ensure the supporting strength of the push member 35 as a whole. In the embodiment of the present application, the push member 35 is made of high-strength steel.

[0028] The outer diameter of the base 370 is greater than or equal to the outer diameter of the limiting portion 351. On the one hand, the base 370 can be used to increase the support force of the push member 35, and on the other hand, it can ensure the reliability of the assembly of the fastening nut 37 and the push member 35. The base 370 is provided with an opening 371, and an adjustment tool can be inserted into the opening 371 and rotated to adjust the assembly height of the fastening nut 37 and the screw rod 36.

[0029] A buffer block 32 is provided between the wedge-shaped block 31 and the push member 35. The buffer block 32 is assembled to the bottom of the wedge-shaped block 31 by means of a first screw 33. An arc portion 311 is provided on the top of the wedge-shaped block 31. The radius corresponding to the arc portion 311 is the same as the radius of the steel pipe 1 and the arc portion 311 is welded to the steel pipe 1. The infrared transmitter 4, the infrared receiver 5, and the two-way infrared signal device 6 are all provided between the two buffer blocks 32 at the bottom of the corresponding wedge-shaped block 31.

[0030] The working principle of the vertical deformation repair device for steel pipe supports of the present application is as follows: when the infrared receiver cannot receive the signal emitted by the infrared transmitter, it means that the steel pipe support has been vertically deformed and needs to be repaired, that is, it may be due to uneven force on the steel pipe causing up and down offset or settlement of the column due to geological conditions. At this time, the on-site staff needs to use relevant tools to adjust the adjustment support under each section of the steel pipe support through a rotation action. Each adjustment support has the function of independent adjustment and does not affect each other. Adjust the adjustment support according to the on-site situation, insert the tool into the opening on the corresponding fastening nut base and rotate it. The fastening nut is acted upon by force and then moves vertically along the thread direction of the screw. It can rise or fall as needed until the infrared transmitter on the wedge-shaped pad coincides with the axis of the infrared receiver, that is, when the infrared receiver receives the signal from the infrared transmitter, it means that the steel pipe support has been successfully reset and the vertical deformation has been repaired. After the vertical deformation of the steel pipe support is repaired, the relevant tools are removed from the opening of the fastening nut.

[0031] When the steel pipe support undergoes a large vertical deformation, the device still has a certain bearing capacity and can restore the support immediately through simple operations. In order to prevent the steel pipe support's bearing capacity from seriously decreasing, thereby causing serious deformation or instability of the foundation pit, the bolt connections between the various mechanisms should not be damaged during the repair of the steel pipe support's vertical deformation to maintain the safety of the steel pipe support system.

[0032] The present application is described through several specific embodiments, and those skilled in the art should understand that various changes and equivalent substitutions can be made to the present application without departing from the scope of the present application. 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.
