Embodiment Construction

[0019] The present invention will be further described below in conjunction with accompanying drawing, protection scope of the present invention is not limited to the following:

[0020] Such as Figure 1~3 As shown, a construction method for fast hoisting of steel cages connected to walls with low headroom, the steel cages 6 are hoisted by crawler cranes and hoisted in sections. After the steel cage 6 is manufactured, the reserved sections on the steel cage 6 are divided into sections, and hoisted in sections according to the sequence of "bottom to top". The sectioning method is as follows: turn the sleeve wire opening connecting the entire reinforcement cage 6 with the main reinforcement 8 and reinforcement of the lower section to the upper reinforcement cage 6 wire opening, and after each interface is turned up, check whether the main reinforcement 8 and reinforcement are all separated , After the inspection and acceptance is completed, the reinforcement cage 6 can be lift...

Abstract

The invention discloses a rapid hoisting construction method for a low-clearance diaphragm wall reinforcement cage. The method comprises a construction preparation process, a reinforcement cage manufacturing and processing process, a hoisting and lowering process and a reinforcement cage meeting the operation of each construction process, the upper part of the reinforcement cage is provided with main reinforcements, trusses, a cage top and horizontal reinforcements, a hoisting rigging, a winch and a hoisting point are arranged on the upper portion of the reinforcement cage, the hoisting rigging comprises a pulley block, a small carrying pole, a shackle A, a steel wire rope and a shackle B, and the two ends of the steel wire rope are connected with the small carrying pole and the shackle B respectively. The method has the beneficial effects that the problems of hoisting, turning and straightening, groove entering, connecting and the like of the underground diaphragm wall reinforcement cage are solved through a hoisting equipment hoisting frame suitable for the low clearance condition.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a construction method for fast hoisting of a steel cage connected to a wall with low headroom. Background technique [0002] During the construction of deep foundation pit enclosure structures in municipal engineering (especially subway stations), the more commonly used enclosure structures are underground diaphragm walls. The underground diaphragm wall is a kind of trenching machine used on the ground for basic engineering. Along the peripheral axis of the deep excavation project, a long and narrow deep trench is excavated under the condition of mud retaining wall. After the trench is cleaned, it is hung in the trench Reinforcement cages, and then use the conduit method to pour underwater concrete to form a unit tank section, so that a continuous reinforced concrete wall is built underground, with high safety, good overall rigidity, good anti-leakage performance, and mature...
