Abstract

The invention relates to the field of building construction, in particular to a foundation treatment method of buildings, which can eliminate earthquake disasters and solve the problems that the existing building foundation poured by rigid concrete has poor toughness, no modulus of resilience and low bending strength and can not resist the earthquake disasters. The foundation treatment method comprises the following steps of: leveling the rigid concrete layer, and then pouring a layer of elastic concrete which is prepared by Portland cement, sand, cobbles, a concrete complexing agent, bromine, rubber particles and an elastic additive. The elastic layer can be bonded with the rigid concrete layer firmly, forms a concrete structure which is compact, has elongation rate, elasticity, toughness, pressure strength of 60MPa, improves bending strength by four times than the pressure strength, leads the foundation platform to have modulus of resilience and can consume the impact energy of earthquake waves so as to guarantee to isolate destructive force of the earthquake waves to the buildings on the ground and solve a big problem which is difficult to overcome for the construction of the foundation of the building.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a building foundation treatment method capable of eliminating earthquake disasters. Background technique [0002] Earthquake is a general term for crustal vibrations caused by internal and external geological actions. It is a natural phenomenon when the crustal movement changes sharply at certain stages. How to do a good job of earthquake resistance and earthquake resistance is in front of people all over the world. An eternal problem, especially in modern metropolises, where there are many high-rise buildings. Once an earthquake disaster occurs, these high-rise buildings will become piles of rubble in an instant. In order to minimize the disasters caused by earthquakes, people continue to improve the structure of buildings to further improve their earthquake resistance, especially the handling of different bases. At present, there are many mature foundation treatment method...
