ARTIFICIAL SOIL ARCH-BASED SHAPE-ADJUSTABLE SOFT FOUNDATION REINFORCEMENT MEMBER

摘要

The present invention relates to an artificial soil arch-based shape-adjustable soft foundation reinforcement member, comprising a soilbag and internal filling materials, several base belts and inner truss belts provided on the soilbag, a lifting belt and a locking device; the soilbag is of a regular polygonal prism, and a plurality of base belts are provided on the bottom, the periphery and the top of the soilbag, and correspond to the diagonal lines of the regular polygon respectively; multiple inner truss belts are provided inside the soilbag, the bottoms of the inner truss belts are connected to the base belts, and the tops thereof are connected to the lifting belt, the bottom end of the lifting belt is connected to the central point of the bottom of the base belt and extends through the interior of the soilbag to above the top of the soilbag, and the locking device is provided at a position where the lifting belt intersects the top of the soilbag. The present invention can form an arched recess at the bottom of the member, reduces the transmission of vertical loads to the interior of the foundation while consolidating shallow stratum surcharge load of the soft foundation, thereby reducing the sedimentation of the soft foundation, and achieving highly efficient, low power consumption and environmentally friendly reinforcement treatment on the soft foundation.
