Description

Soil machine is inhaled to dregs in stake hole

Technical Field

Background

For large buildings, such as bridges, high buildings and the like, the first task in the construction process is to make pile holes, and then put reinforcement cages in the pile holes, wherein the heights of the reinforcement cages and the depths of the pile holes are in one-to-one correspondence. However, in the field construction process, constructors find that the reinforcement cage is often 2-5 meters higher than the ground level after being placed completely, and cannot be completely placed at the bottom of a pile hole, and a general operation method is to cut off the reinforcement cage higher than the ground level or directly perform construction, so that the real strength of a building cannot reach the design strength really required, and serious safety problems may be caused subsequently.

After field exploration of researchers, the reason that the reinforcement cage cannot be completely transferred to the bottom of the pile hole is found to be that the reinforcement cage can touch the hole wall of the pile hole in the transfer process, soil on the hole wall of the pile hole is knocked down to the bottom of the pile hole, and the soil occupies a certain space at the bottom of the pile hole, so that the reinforcement cage cannot be completely transferred, particularly, in a filled mountain or a soil dune, the soil is loose, and the knocked-down soil is more, so that a soil suction device is needed to be adopted to suck out the residue soil at the bottom of the pile hole, and then the reinforcement cage is transferred. However, because the pile hole is too deep, at present, there is no soil suction machine for sucking soil at the bottom of the pile hole, and only a rotary drilling rig can be used for drilling, but the soil which can be taken out by the rotary drilling rig each time is very little, one day of time is basically needed for drilling the soil in one pile hole, a plurality of pile holes are formed in one construction site, dozens of days or even one month is needed for drilling the soil at the bottom of each pile hole, and the construction progress is seriously influenced.
