Integral hoisting device and method for super-long steel reinforcement cage of underground continuous wall

Abstract

The invention relates to an integral hoisting device and method for a super-long steel reinforcement cage of an underground continuous wall. The device comprises a main hoisting device and an auxiliary hoisting device, wherein the main hoisting device comprises a main hoisting hook (1), a main carrying pole beam (3), a main pulley (5), a main hoisting rope (7), a first hoisting point (9), a second hoisting point (10) and a third hoisting point (13); and the auxiliary hoisting device comprises an auxiliary hoisting hook (2), an auxiliary carrying pole beam (4), an auxiliary pulley (6), an auxiliary hoisting rope (8), a fourth hoisting point (11) and a fifth hoisting point (12). The method comprises the following steps: S1, setting the hoisting points on the steel reinforcement cage; S2, installing the main hoisting rope and the auxiliary hoisting rope on the hoisting points and the pulleys; S3, lifting the main hoisting hook and the auxiliary hoisting hook; S4, unhooking the auxiliary hoisting hook, and taking down the auxiliary carrying pole beam and the auxiliary pulley; S5, moving the main hoisting hook, and dismantling the auxiliary hoisting rope; S6, taking down the main hoisting rope from the second hoisting point; and S7, putting down the steel reinforcement cage in place. The device and the method have the advantages of high safety and low construction lost, the hoisting steps is simplified, and the construction efficiency is accelerated.

Description

technical field [0001] The invention relates to the field of building construction, in particular to an integral hoisting device and method for an ultra-long or ultra-deep steel cage of an underground continuous wall. Background technique [0002] As a continuous underground enclosure structure constructed to support building loads, water cutoff and seepage prevention, or soil retaining support, the underground diaphragm wall has the advantages of high rigidity, strong integrity, and good displacement control effect. become the main form of support. [0003] The reinforcement cage of the conventional reinforced concrete underground diaphragm wall is made in sections, and the slots are connected when it is hoisted. The reinforcement cage is relatively short and the lifting is relatively simple. The super-long reinforcement cage of the reinforced concrete ground connection wall is thicker and takes a long time to connect the joints. In recent years, its development trend is t...
