Liftable operation platform for soft soil foundation construction and building method

Abstract

The invention provides a liftable operation platform for soft soil foundation construction and a building method. The liftable operation platform comprises an inflatable cushion, a force transmission platform, an operation platform, latticed columns and hoisting mechanisms, wherein the inflatable cushion is placed on a soft soil foundation in a foundation pit, the force transmission platform is placed on the inflatable cushion, the latticed columns are evenly fixed to the force transmission platform, the hoisting mechanism is installed at the upper end of each latticed column, and the hoisting mechanisms drag the periphery of the operation platform through hoisting chains, so that the operation platform are lifted. The scheme of modular combination, simple assembly and disassembly and repeated turnover is adopted, a novel operation platform system is designed, and on the premise that the construction requirement under the soft soil foundation condition is met, the construction time is greatly shortened, engineering resources are saved, the engineering cost is reduced, and the lifting difficulty of the platform is reduced; and therefore, the technical problem can be solved conveniently and effectively by adopting the turnover foundation pit support inner support construction operation platform system under the condition of soft soil texture.

Description

technical field [0001] The invention relates to the technical field of internal support construction of foundation pit support at a building construction site, in particular to a liftable operation platform and a construction method for soft soil foundation construction. Background technique [0002] With the development of society, current construction projects generally design underground structures with more than one floor to meet the structural safety and parking requirements. Therefore, many construction projects are affected by factors such as excavation depth, soil quality and surrounding construction environment. Carry out deep foundation pit support construction first. The deep foundation pit generally consists of two parts, the arm guard and the inner support. The common internal supports include pipe support, section steel support, reinforced concrete support, combined support of section steel and reinforced concrete, etc. However, under some deep soft soil foun...

AI Technical Summary

Problems solved by technology

[0003] The inventor of the present application has developed a soft soil foundation construction support internal support construction operation platform, the patent number is 202110274047.7. This platform can solve the problems that the soft soil foundation is difficult to level and the construction operation platform is difficult to turn over and install. The lifting operation procedure is more complicated. It is inconvenient for the operator to change the height of the operation surface after completing the construction of the part near the bottom surface in the foundation pit.
