Hole-forming method for disposing construction garbage soil, miscellaneous fill and other complex geological conditions

Abstract

The invention relates to the technical field of building construction, in particular to a hole-forming method for disposing construction garbage soil, miscellaneous fill and other complex geological conditions. The method aims to solve the technical problems that under special geological conditions, such as when miscellaneous fill, construction garbage soil and loose block rock soil exist in the foundation, during the hole-forming process, the foundation is easy to collapse, the construction period is prolonged, and the cost is increased; the method comprises the following steps of: excavatingto design elevation in sections, backfilling a viscous fine-grained soil retaining wall in layers from top to bottom and ramming backfill soil by using a heavy hammer. The method has the advantages that the backfill soil can be better penetrated into the soil around piles, the soil between the piles has a better compaction effect and can meet the requirements more easily, by adopting the method,overlong hole formation can be realized when miscellaneous fill, construction garbage soil and loose block rock soil exist in the foundation, the collapse of soil in the hole-forming process can be avoided, the cost is reduced and the feasibility is strong.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a method for forming holes under complex geological conditions such as processing construction waste soil and miscellaneous filling soil. Background technique [0002] In many areas, the problem of soil collapse is often encountered. In order to eliminate the collapse of miscellaneous filling soil, loose gravel soil, and construction waste soil under complex geological conditions, and at the same time must achieve the goal of reducing the cost, traditional foundation The treatment methods mainly include: (1) heavy hammer surface compaction, (2) replacement cushion, (3) compaction pile method, (4) heavy hammer dynamic compaction, among the above treatment methods for the foundation, the first two methods can only Treatment of shallow foundations; the compaction effect of method (3) is not ideal, and the range of fillers used in the "retaining wall" is narrow; Under ...

Problems solved by technology

[0003] In order to solve the technical problem that under special geological conditions, such as when there are miscellaneous filling soil, construction waste soil and loose rocky soil in the foundation, the process of hole formation is prone to collapse, resulting in prolonged construction period and increased cost, it provides a A hole-forming method for dealing with complex geological conditions such as construction waste soil and miscellaneous filling soil; it can avoid large-scale subsidence when digging pile holes, which will cause serious consequences for rework, and at the same time can realize ultra-long and ultra-deep pore formation
