Large-span cable-stayed locking dewatering operating platform and construction method thereof
The invention provides a large-span cable-stayed locking dewatering operating platform and a construction method thereof. The large-span cable-stayed locking dewatering operating platform and the construction method aim to solve difficult problems of excessively long distances from pressure reduction well pipes to braces and excessively large span of existing platforms in foundation pit dewatering procedures in the prior art. The large-span cable-stayed locking dewatering operating platform is used for bracing a dewatering well and comprises a steel platform, a detaching clip and steel wire ropes. One end of the steel platform is arranged on a second brace and is used as a fixed end, the other end of the steel platform outwardly extends in a cantilever manner to be used as a cantilever end, the dewatering well is arranged at the cantilever end of the steel platform, the detaching clip is arranged on a first brace, one end of each steel wire rope is pulled by the detaching clip, and the other end of each steel wire rope is connected onto a position, which is close to the dewatering well, of the steel platform. The large-span cable-stayed locking dewatering operating platform and the construction method have the advantages that the steel platform is arranged on the second brace, the detaching clip can be arranged on the first brace, the positions, which are close to the dewatering well, of the steel platform can be pulled by the detaching clip, the steel platform can be turned into a 'simply supported beam' form from a 'cantilever beam' form, accordingly, brace pressures on the fixed end of the steel platform and bending moment which is generated by upper loads on the fixed end can be relieved, and the stability and the safety of the integral operating platform can be improved.
