Horizontal drainage system for mud soft soil foundation and its drainage construction method

Abstract

The invention relates to a level draining system for mud texture soft soil foundation and draining construction method thereof. drainage ditches are arranged around the mud texture soft soil foundation; a layer of silver sand are laid on the mud texture soft soil foundation; vertical plastic drain bars are inserted with intervals from the silver sand into the mud texture soft soil foundation; theupper part of the drain bar is bent to the level surface of the silver sand; level plastic drain bares are fixed on the bent parts of the vertical plastic drain bars; the level plastic drain bar comprises a latitudinal level plastic drain sub-bar and at least two longitudinal level plastic drain sub-bars; the latitudinal level plastic drain sub-bar is arranged along the length direction of the foundation pressing against the bent part of the level plastic drain bare with the two ends extending to the drainage ditch around the mud texture soft soil foundation; the longitudinal level plastic drain sub-bar is parallel with the foundation length direction and presses against the latitudinal level plastic sub-bar. The invention solves the problems of high complexity, high cost and no guaranteeto construction progress existing in the mud texture soft soil foundation draining construction.

Description

technical field [0001] The invention relates to a foundation drainage system and a drainage construction method thereof, in particular to a drainage system and a drainage construction method of a muddy soft soil foundation. Background technique [0002] Usually, in the process of soft foundation treatment, the drainage layer in the horizontal direction adopts a well-graded, low mud content, and meets the requirements of coarse sand layers, but in areas with deep soft soil layers, especially muddy soil areas, it meets the requirements. Coarse sand resources are very scarce, and it is impossible to obtain materials locally. It is necessary to find suitable materials from a distance, so the price is high, and the quality and quantity of supply are unstable. Usually, the mud content exceeds the standard, and the drainage effect is not good, which affects the consolidation of underground soil. With the settling speed, it is difficult to meet the schedule requirements. In additio...
