Abstract
The invention discloses a method for hoisting and constructing reinforcement cages of concrete diaphragm walls. The method includes steps of (1), constructing high-water-level foundation pit supports; (2), hoisting travel paths according to construction requirements, in other words, selecting constructed circle paths according to the weights of the hoisted reinforcement cages, and generally adopting rigid concrete pavements with the thicknesses of 20cm as the travel paths for cranes; (3), selecting reinforcement cage processing sites, and in other words, determining the positions and the quantity of the reinforcement cage processing sites according to the standard requirement that the travel distance of each loaded caterpillar crane is not longer than 50m. The bearing capacity of foundations of the constructed circle paths needs to meet computing requirements. The method has the advantages that the long and heavy reinforcement cages which have gravity centers difficult to determine and are easy to deform can be easily and conveniently hoisted by the method, the hoisting efficiency is high, the safety is good, and the reinforcement cages can be effectively protected against deformation.

Be subject to each side restriction in China's urban ground traffic, flourishing urban traffic pressure is increasing, and underground traffic is in Rapid development stage, goes along with sb. to guard him and adopt the form of ground-connecting-wall more and more when underground construction.Reinforcing bar cage hoisting is the pith in ground-connecting-wall construction, and this engineering method is very important for the completing property of reinforcing cage and the safety of reinforcement cage hoisting, agility.
Summary of the invention
The object of this invention is to provide a kind of irregular, weight is large, yielding ground-connecting-wall reinforcing bar cage hoisting construction method; select this method lifting; be difficult to determine for center of gravity; large, the yielding reinforcing bar cage hoisting of length weight; lift very easy; lifting efficiency is higher, and safety is better, and the distortion of protection reinforcing cage is very good.
Technical scheme of the present invention is as follows:
Ground-connecting-wall reinforcing bar cage hoisting construction method, is characterized in that, comprises the following steps:
(1) high water level bracing of foundation pit construction;
(2) construction requirement of lifting walking road;
According to the weight of lifting reinforcing cage, select the perimeter path built, the circumferential road bearing capacity of foundation soil of building must meet calculation requirement, generally adopts rigid concrete road surface that 20cm the is thick walking road as crane.
(3) select reinforcing cage processing place;
According to code requirement, crawler crane when walking load travel distance must not exceed 50m and determine that reinforcing cage processes position and the number in place;
(4) processing of reinforcing cage construction
Select the tonnage number of crawler crane lifting according to the weight of reinforcing cage, then select the processing of reinforcing cage entirety or segmental machining according to sling height, and determine the length of every section;
(5) reinforcing cage hoisting point position and suspension centre Reinforcement Measures
According to the length of reinforcing cage and plane position of centre of gravity, select reasonably longitudinally to lift by crane number, span all guarantees in 10m, hoisting point position should be chosen in the vertical transverse truss intersection point of reinforcing cage place, the suspension ring of reinforcing cage adopt round steel to make ∏ type according to calculating, the main longitudinal reinforcement welding in following and bottom surface, weld with the main longitudinal reinforcement in top on top mouthful, lengthways main steel bar and the whole full welds of transverse horizontal muscle in the scope of reinforcing cage body suspension centre 1m;
(6) instrument of lifting
When reinforcement cage hoisting, adopt two crawler cranes, under drop hanger, shoulder pole is set, shoulder pole is divided into pulley, and on pulley, wire rope adopts snap ring to link with the suspension centre of reinforcing cage;
(7) reinforcing cage is installed
Reinforcing cage adopts two crawler cranes to carry out parallel lifting, and when the about 1m of reinforcement cage hoisting is high, main hoisting 1 starts to promote, utilize the pulley on shoulder pole to complete turning of reinforcing cage, after ground-connecting-wall reinforcing cage is vertical, removes pair and hang 2, utilize main hoisting transportation reinforcing cage to notch, after artificial righting, start to transfer reinforcing cage.
Ground-connecting-wall reinforcing bar cage hoisting of the present invention, adopts the parallel lifting of major-minor crawler crane, has reduced the degree of difficulty that reinforcement cage hoisting is turned.Guarantee the distortion of reinforcing cage, simplified the transportation of reinforcing cage, in each operation of construction and link, carried out meticulous planning, in work progress, constantly optimized, guaranteed construction safety and quality.
