Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: when the reinforcement cage is limited by wooden pressure or other devices, the stress generated when the reinforcement cage floats is mainly concentrated at the pile mouth, and the force of the reinforcement cage is uneven, making the reinforcement cage Cages tend to shift when pouring concrete, which is not conducive to improving the forming quality of cast-in-place piles

Embodiment Construction

[0046] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0047] refer to figure 1 and figure 2 , is a kind of manual hole-digging pile structure disclosed by the present invention, comprising a pile hole 1, a retaining wall 2 and a steel cage 3, the pile hole 1 is opened on the ground, the retaining wall 2 is preferably a steel plate retaining wall, and the steel plate retaining wall is fixedly erected in the hole of the pile hole 1 Wall, to prevent the collapse of the pile hole 1, the reinforcement cage 3 is located in the pile hole 1, and the reinforcement cage 3 includes several main reinforcements 301 distributed in a circle and stirrups 302 fixedly connected to the outside of the several main reinforcements 301.

[0048] refer to figure 2 and image 3 There are three fixing holes 4 distributed along the vertical direction on the side of the retaining wall 2 away from the hole wall of the pile hole 1, four...

Abstract

The invention relates to the technical field of building construction, in particular to a manual hole digging pile structure. The manual hole digging pile structure comprises a pile hole, a protectivewall and a steel reinforcement cage, wherein the pile hole is formed in the ground, the protective wall is fixedly connected with the hole wall of the pile hole, the steel reinforcement cage is positioned in the pile hole, the protective wall is provided with a plurality of fixing holes, the steel reinforcement cage is fixedly connected with a plurality of fixing cylinders in one-to-one correspondence with the fixing holes in position, fixing rods matched with the fixing holes in an inserted mode are matched in the fixing cylinder in a sliding mode, and a transmission mechanism for driving the fixing rods to slide along the fixing cylinders is arranged in the steel reinforcement cage. The manual hole digging pile structure has the effect that the steel reinforcement cage is not prone to shifting when concrete is poured, and accordingly has the effect of improving the forming quality of a cast-in-place pile.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to an artificial hole-digging pile structure and a pouring method for the hole-digging pile. Background technique [0002] The manual digging pile refers to the pile that is made by manual digging, then the steel cage is placed, and the concrete is poured. The manual digging pile is one of the important pile forming methods. It has the advantages of flexible pile diameter and high construction efficiency. Advanced features are widely used nowadays. In order to ensure the safety of the staff when excavating the pile holes, protective walls are generally set in the pile holes. [0003] In the process of pouring concrete after the existing manual digging piles are placed with reinforcement cages, the reinforcement cages are likely to float up due to the buoyancy of the concrete, so that the quality of the cast-in-situ piles after forming is poor, and the reinforcement cag...
