Problems solved by technology
[0003] However, in areas where the soil is relatively loose, direct pouring can easily lead to the collapse of the soil at the entrance of the hole, and the collapsed soil makes the pile body mixed with a large amount of soil residue, which greatly affects the quality and strength of the pile body, and also It is easy to cause deformation of the pile body, so enclosure is required during pouring
[0004] At present, the existing enclosure device cannot adjust the width according to the actual working conditions, and the existing enclosure device is extremely inconvenient to disassemble and install. Therefore, the present invention proposes a new concrete pouring enclosure device for pile foundation construction

The invention provides a concrete pouring enclosure device for pile foundation construction. The device comprises a width adjusting device and a plurality of arc-shaped enclosure plates. Limiting plates are fixedly arranged on the two sides of each enclosure plate, and a limiting column penetrates through the middle of each limiting plate. Fixing connecting devices are arranged at the upper ends and the lower ends of every two adjacent enclosure plates; each fixing connecting device comprises a screw rod and a plurality of fixing nuts; the screw rods sequentially penetrate through the two adjacent enclosure plates and are fixed through the multiple fixing nuts; the width adjusting device comprises a moving device, two frame plates arranged front and back and clamping plates arranged left and right; the moving device is fixedly erected between the two frame plates and drives a sliding block to slide up and down; two sets of connecting rod devices are symmetrically arranged on the two sides of the sliding block; and the two sets of connecting rod devices drive the two clamping plates to synchronously move oppositely or reversely. The concrete pouring enclosure device for pile foundation construction is convenient to disassemble, and the width can be adjusted under a target working condition.
Description
technical field [0001] The invention relates to the technical field of construction engineering, in particular to a concrete pouring enclosure for pile foundation construction. Background technique [0002] The pile foundation is composed of the foundation pile and the cap connected to the top of the pile. If the pile body is completely buried in the soil and the bottom of the cap is in contact with the soil, it is called a low cap pile foundation. If the upper part of the pile body is exposed to the ground and bears If the bottom of the platform is above the ground, it is called a high cap pile foundation. Generally, during the construction of the low-cap pile foundation, due to the large burial depth of the pile foundation, the hole is generally opened first, and then pouring is directly carried out in the hole. [0003] However, in areas where the soil is relatively loose, direct pouring can easily lead to the collapse of the soil at the entrance of the hole, and the col...
