SURFACE LAYER TREATMENT METHOD FOR SOFT GROUND AND ITS DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a surface layer treatment method for the soft ground by the use of a flexible planar reinforcing member such as sheet and a net to give rigidity to the flexible planar reinforcing member by a comparatively simple rigid reinforcing body and install the rigid reinforcing body on the soft ground easily at a low cost. SOLUTION: The flexible planar reinforcing member 11 such as sheet and a net is provided on the soft ground 1. A flexible linear hollow body 13 composed of a hose having dewaterbility and high tensile strength is arranged or attached in advance on at least either of the upper face and the lower face of the planar reinforcing member 11. Mortar 14 is filled into the linear hollow body 13 to form the lattice-like rigid reinforcing body 12. The load of sediment loaded through the planar reinforcing member 11 is dispersed by the rigid reinforcing body 12 having a frame structure allowing easy istallation and having high rigidity, and the destruction and deformation of the soft ground are suppressed to perform stable sediment work such as soil covering and filling.
