Embodiment Construction

[0027] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0028] Such as figure 1 , figure 2 , image 3 and Figure 4 As shown, a layered binding construction method in a large-diameter pile foundation reinforcement hole disclosed by the present invention specifically includes the following construction steps:

[0029] S1: Deepen the construction drawing. According to the reinforcement diagram of the pile foundation and the site construction conditions, the reinforcement arrangement of the pile foundation is deepened, and the reinforcement cage 2 and the operation frame 3 are designed according to the size of the pile diameter and the arrangement and spacing of the reinforcement. For each type A deepened drawing of reinforcement cage 2 and operating frame 3 and a deepened diagram of reinforcement arrangement shall be issued for the piles. The arrangement of the operation frame 3 is determined according to the i...

Abstract

The invention discloses a large-diameter pile base reinforcing steel bar in-hole layering and bundling construction method. The large-diameter pile base reinforcing steel bar in-hole layering and bundling construction method comprises the following steps: layering a reinforcement cage, limiting and manufacturing a reinforcement reinforcing cage and an operating frame, fixing and hoisting the operating frame and the reinforcement reinforcing cage into pile holes. The large-diameter pile base reinforcing steel bar in-hole layering and bundling construction method positions the reinforcement cage, and provides an operation platform for a constructor, so that hoisting weight is effectively controlled; and meanwhile, time of arranging the operating frame in the pile holes is reduced, and the operating frame is conveniently arranged. The construction method breaks through an existing common reinforcement cage construction way; and the reinforcement cage is bundled in the pile holes, so thatthe defects that the large-diameter reinforcement construction difficulty is great, hoisting is difficult, hoisting quality is not easily controlled, and potential safety hazards are easily generatedin the prior art are solved.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a layered binding construction method in a large-diameter pile foundation reinforcement hole. Background technique [0002] With the development of the city, the population is increasing, the land is getting less and less, and super tall buildings are constantly emerging. In complex geological regions, large-diameter pile foundations are often used for super-tall buildings. For the construction of conventional diameter pile foundation reinforcement, the binding of the reinforcement cage is generally completed outside the pile hole, and then the bundled reinforcement cage is lifted into the pile hole as a whole by a tower crane or a crane. However, for some large-diameter pile foundations with excessively large diameters, long pile bodies, and more steel bars required for design, especially in large-diameter pile foundations that are often designed in su...
