Method for anti-floating of underground building

Abstract

The invention discloses a method of underground structure against floating, which is characterized by the following: 1)adopting the following methods; a)arranging first drained hole (7)on lower of underground structure outside wall (5); b)arranging second drained hole (8)on underground structure bottom plate (3); c)arranging the first drained hole (7)on the lower of the underground structure outside wall (5); arranging the second drained hole on the underground structure bottom plate (3); 2)arranging drained tank (2)on the inner of the underground structure exterior wall; communicating with collecting well (1)in the underground structure; 3)discharging the water in the collecting well out of the underground structure; arranging third drained hole (9)on the wall of the collecting well (1);proceeding pressure poured cement paste under the underground structure bottom plate (3); change-filling backfill soil (6)of the underground structure outside wall (5)in the zone with big creep quantity. This invention possesses the advantages of simple and firm.

Description

A method for anti-floating of underground structures technical field The invention relates to a method for anti-floating of an underground structure. Background technique When the soil covering weight of underground buildings is not enough, under the action of surface water and groundwater, floating phenomenon often occurs. When the underground structure floats, it will be accompanied by the cracking and damage of the structural bottom plate and column, which is difficult and costly to remedy. With the rapid development of my country's economy, a large number of urban underground garages have emerged. These underground garages are often single-storey basements, and the weight of the structure itself is difficult to balance the buoyancy of water. Recently, accidents that cause single-storey basements to float have occurred frequently. At present, there are three ways to prevent underground buildings from floating: one is to increase the weight of the structure itself, su...

Problems solved by technology

The cost of the above three methods is very high, and the construction period of the latter two methods is also long, especially when the underground buildings have been floated, it is more difficult to use the above methods to remedy
