Description

Technical Field

[0001] The utility model relates to the technical field of steel support erection, and more particularly to an eccentric repair device for steel support erection in a semi-excavated subway station. Background Art

[0002] With the acceleration of urban modernization, subway station construction generally adopts the open-cut method. This method is suitable for stations with few surrounding structures and no road occupation. However, it is inevitable that many stations are located at the main traffic arteries in the urban area. Therefore, in order to ease the traffic pressure and ensure the smooth progress of construction, the cover-cut method is adopted in such an environment. This method is to restore the original road surface after the construction of the retaining structure is completed, reserve a construction operation well, excavate the earth from the well and transport it out, erect steel supports until the bottom of the station, and then construct waterproofing and concrete structures.

[0003] Based on the above, the inventors found that the existing steel support structure only suspends and supports the steel plate through traction tools during the installation and disassembly of the steel plate, and has no other limiting structure, which easily causes the entire steel plate to shake and increases the risk during the operation. Therefore, in view of this, the existing structure is studied and improved, and an eccentric repair device for the steel support structure of a semi-covered subway station is provided, in order to achieve a more practical purpose.

[0016] 3. Beneficial effects

[0017] Compared with the prior art, the advantages of the present invention are:

[0018] (1) This solution sets an active rod to drive two driven screws to rotate synchronously, so that the ball slider drives the sliding plate to slide vertically on the outside of the support frame, and at the same time drives the sliding sleeve to slide in the middle of the support frame, thereby adjusting the unloading position of the steel plate. After arriving at the designated location, the support plate is separated from the bottom surface of the steel plate, completing the disassembly of the steel plate.
