Description

Technical Field

[0001] The utility model relates to the field of construction, in particular to an auxiliary device for prolonging the bundling of a large-diameter pile foundation steel reinforcement cage. Background Technique

[0002] When pouring concrete for a large-diameter deep-hole pile foundation, the bundling of the steel reinforcement cage is divided into two types. One is to bundle the steel reinforcement cage once on the ground, and after the retaining wall construction of the pile foundation hole is completed, the whole steel reinforcement cage is hoisted into the pile foundation for concrete pouring. The other is to bundle the steel reinforcement cage in the pile foundation hole after the retaining wall construction of the pile foundation hole is completed.

[0003] Bundling the steel reinforcement cage once on the ground is difficult to ensure the accurate position of the steel reinforcement cage in the pile foundation hole for a large-diameter deep-hole pile foundation, and its practical application is limited. Especially when the concrete pouring of the pile foundation is completed, due to design changes and other reasons, if it is necessary to extend the already poured large-diameter pile foundation upwards, there are two ways to connect the steel bars of the extended section with the steel bars of the already poured part one by one. Method 1: Bundle the steel reinforcement cage of the extended section of the large-diameter pile foundation on the ground and hoist the whole into the pile foundation hole to connect with the steel bars of the already poured part of the pile foundation one by one. Method 2: Connect the steel bars of the extended section of the large-diameter pile foundation in the pile foundation hole with the steel bars of the already poured part of the pile foundation one by one to form an integral body. Using Method 1, in the construction of connecting the steel reinforcement cage of the extended section in the pile foundation hole with the already poured steel bars one by one, it is very difficult to achieve one-to-one fixed connection for each main reinforcement due to errors in length, positioning, etc. Using Method 2, connecting the steel bars of the extended section of the large-diameter pile foundation in the pile foundation hole with the steel bars of the already poured part of the pile foundation one by one to form an integral body has low construction efficiency and large workload.

[0004] In short, it is difficult to bundle the steel reinforcement cage of the extended section of the large-diameter pile foundation in the pile foundation hole after the retaining wall of the pile foundation hole is completed, with low construction efficiency, long construction period and high construction cost.
