Abstract

The invention provides a construction method for an underground diaphragm wall of a square. The construction method comprises the following steps of a reinforcement cage hoisting step and a counter-force box hoisting step, specifically, the reinforcement cage hoisting step comprises the following steps of setting a transverse suspension centre and a longitudinal suspension centre; judging whethera reinforcement cage meets the hoisting demand; carrying out ground bearing checking calculation of a construction load on a ground load and a foundation bearing capacity; carrying out checking calculation on stability of a crawler crane; mounting the reinforcement cage by using a single crane or a double crane; the counter-force box hoisting step comprises the following steps: carrying out hoisting checking calculation on the counter-force box and calculating a hoisting steel wire rope; configuring the counter-force box in section according to depth of a groove section; mounting the counter-force box; and pulling out the counter-force box. According to the construction method provided by the invention, reinforcement cages and counter-force boxes which are relatively long and relatively heavy can be constructed, so that the problem that reinforcement cages and counter-force boxes which are relatively long and relatively heavy cannot be constructed in the prior art is solved.

Description

technical field [0001] The invention relates to an underground wall construction technology, in particular to a construction method for an underground continuous wall in a square. Background technique [0002] The existing underground diaphragm wall construction technology is becoming more and more mature. For the steel cage and reaction box with shorter length and lighter weight, the existing underground diaphragm wall construction technology can be used to hoist well. Yet for the steel cage and the counter force box that length is longer, the weight is bigger, but can't carry out construction. Contents of the invention [0003] An embodiment of the present invention provides a construction method for an underground diaphragm wall in a plaza, which is used for hoisting a long-length and heavy-weight steel cage and a reaction box. [0004] In order to achieve the above purpose, an embodiment of the present invention provides a construction method for an underground diaphr...
