Foundation soil consolidation method

Abstract

The invention relates to a foundation soil consolidation method which is simple and reasonable. The ground surface settlement and the ground surface settlement rate are observed and calculated through a settlement scale board, the heap loading rate is reasonably controlled, the blind excessive heap loading situation is avoided according to the actual condition, and therefore the whole construction process is economical and reasonable; according to detection data, it is obtained that the consolidation change of soil is very small after first-stage heap preloading is performed for ten days, two-stage heap loading can be performed, construction does not need to be performed according to most of the designs that first-stage heap loading needs a 30-day preloading process, and the consolidation degree of the soil is more than 90 percent when the overall construction period is 60 days. According to the foundation soil consolidation method, plastic drainage plates and blind ditches are closely distributed, therefore, water in the soil can be drained quickly, the water is prevented from flowing back into the soil through the penetration role, and the consolidation process is effectively facilitated.

Description

technical field [0001] The invention relates to a foundation soil consolidation method. Background technique [0002] Weak cohesive soil layers are widely distributed in the southeastern coastal areas of my country, which have high compressibility, poor water permeability, and low strength. The bearing capacity and stability of the foundation often cannot meet the engineering requirements. This kind of foundation usually needs to be treated. Preloading drainage consolidation method is one of the effective methods to deal with soft ground. Using this preloading drainage consolidation method can make the consolidation and settlement of the foundation mostly or basically complete during the preloading period, and accelerate the growth of the shear strength of the foundation soil, thereby improving the bearing capacity and stability of the foundation. [0003] At present, as the scale of urban construction continues to expand, land resources in coastal areas are scarce. my count...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a foundation soil consolidation method according to the current state of the art, which is simple and reasonable, solves the problem of economic waste caused by blind loading in the current construction process, and is convenient for determining the loading time , so that the whole construction process is economical and reasonable
