Pile-embedding method for hollow pile and auger drill for implementing same

Abstract

The invention relates to a pile-embedding method for a hollow pile. The pile-embedding method comprises the following steps of: hoisting the hollow pile to a pile-embedding position and hanging the hollow pile vertical to the ground; penetrating a central through hole of the hollow pile from top to bottom by using an auger drill with a reamer bit to reach the ground and starting to drill and carry soil; after the reamer bit is extended to the underground, carrying soil and expanding the reamer bit at the same time; along with the deep penetration of the drilling and soil-carrying operation, conveying the soil by using the auger drill; and embedding the hollow pile into the drill hole gradually until the hollow pile reaches to the set depth. The invention also provides the auger drill for implementing the pile-embedding method. Due to the construction by the auger drilling, soil-carrying and pile-embedding method, the problems of difficult soil extrusion in the pile-embedding process and difficult pile-embedding operation on hard-soil foundation can be solved; the project schedule is accelerated; the quality of the pile body is guaranteed; and adverse influence of construction on the ambient environment is reduced to a maximum degree.

Description

technical field [0001] The invention belongs to the field of building construction and relates to a pile planting method for on-site construction of building pile foundations and an auger for implementing the method. The method can effectively solve the problems of soil squeezing effect, hard soil quality, noise, environmental pollution and the like. Background technique [0002] At present, at the construction site, the pile planting methods are mainly hammering and static pressure. Hammer pile planting and static pressure pile planting must consider the conditions of the foundation soil to select the model of the finished pile. [0003] In the traditional construction process (including pipe sinking and pipe pulling), the soil at the pile point vibrates due to the excitation of the pile machine, and the soil is used as the medium to propagate to the surrounding area, thereby stimulating the vibration of the surrounding buildings. When the vibration exceeds a certain limit...

AI Technical Summary

Problems solved by technology

When the vibration exceeds a certain limit, it will have adverse effects on the surrounding environment, endanger the stability and safety of surrounding buildings and underground pipeline facilities, interfere with the normal work and life of residents, and may cause some contradictions, which will affect the project cost and adverse effect on progress
