The Method of Strengthening the Building Foundation by Utilizing Quicklime Brick Dregs Compaction Pile

Abstract

The invention relates to a reinforcement construction method for building foundation treatment, in particular to a method for strengthening the foundation of a building by utilizing quicklime brick ballast compaction piles, using quicklime, brick ballast, soil, and cement as raw materials and pouring into the foundation In the pile hole, the pile hole is formed by impact, and the pile end is compacted with brick ballast. The adopted process is: construction preparation→construction setting out→construction precipitation→impact hole forming→layer pouring→tamping and capping. The percussion drill impacts the hole, and the soil between the piles is compacted during the hole formation process. After mixing quicklime, brick slag, soil, and cement raw materials, they are driven into the pile hole of the foundation soil. The quicklime absorbs water and expands to cause secondary compaction of the soil between the piles. effect, the pile end is rammed with brick ballast, and the brick ballast acts as a hard aggregate, making the pile upright and upright, which can effectively increase the strength of the foundation soil, improve the bearing capacity of the foundation soil, improve the uniformity of the foundation soil, and prevent the foundation from being damaged due to Settlement deformation occurs due to uneven force, low cost, no environmental pollution, and can shorten the construction period.

Description

technical field [0001] The invention belongs to the technical field of foundation reinforcement treatment, and relates to a reinforcement construction method adopted for the foundation treatment of a building, in particular to a method for reinforcing the foundation of a building by using quicklime brick compaction piles. Background technique [0002] Concrete pouring piles and cement-soil mixing piles have been mostly used in building foundation treatment for many years, but these prior art ubiquitous following shortcoming: 1, engineering cost is relatively high. For example, if the foundation cost of a general 6-story residential building has a bearing capacity of fak=80-l00KPa, the cost of concrete pouring pile foundation is 80 yuan / m2; the foundation cost of cement-soil mixing pile is 45 yuan / m2, and the natural foundation of quicklime brick compaction pile The construction cost is only 30 yuan / m2; it can be seen that the present invention can effectively reduce the cost...

AI Technical Summary

Problems solved by technology

[0002] For many years, building foundation treatment adopts cast-in-situ piles and cement-soil mixing piles more, but these prior art ubiquitous following shortcoming: 1, engineering cost is relatively high

2. The construction progress is slow

Due to the large and heavy mechanical equipment used in the prior art, the construction period is long, the construction cannot be flexible, and it is also limited by the site, water, electricity, fuel, etc., so the construction progress is affected to a certain extent

3. Pollution and noise

4. The pile quality is limited

Traditional cast-in-place piles and composite foundation treatment methods are mostly based on friction. During construction, affected by groundwater, soil layers, and pile-forming technology, etc., engineering quality problems such as necking, broken piles, concrete segregation, and excessive sediment thickness are prone to occur.
