Construction Technology of Large-diameter Cast-in-place Pile Reinforcement Cage Hoisting and Cast-in-place Pile
At present,in the pile-forming process of large-diameter cast-in-place piles,the reinforced cages and pouring concrete placed and fixed on the top of the pile casing will continue to superimpose loads on the pile casing,which will easily lead to the settlement and deformation of the pile casing in different degrees,and seriously lead to the collapse of the orifice and the quality accident of pouring concrete.Therefore,an independent working platform with openings was developed,in which reinforcing cages were hoisted and fixed in sections by using lifting rings,and reinforcing cages and pouring frames were quickly and accurately centered and positioned by positioning platforms,and the processes of hoisting reinforcing cages and concrete pouring were integrated on the opening platform,so as to achieve the effects of high construction efficiency,reliable quality,safe operation and economical cost.
