Rapid drainage and rapid consolidation construction method for yard silt by using solidified soil as surcharge

Abstract

The invention relates to a rapid drainage and rapid consolidation construction method for yard silt by using solidified soil as surcharge, which is characterized in that a light workboat is used to set blind drains and lay vertical and horizontal drain boards on the surface of a yard, and the vertical drain boards which are bent by 90 degrees are connected with the horizontal drain boards to form a stereo drainage system; and finally field solidified soil is used as the material for surcharge preloading, so that late drainage and consolidation of the yard silt are promoted, and treatment period of the yard silt is shortened. The light workboat is used with a quick spile machine with light open wedges for treating the yard silt, so that the blind drains and the drain boards can be laid on the surface of the yard for high water content and low strength silt by constructors using the equipment. The vertical and horizontal drain boards are connected together in a flexible and attached manner, so that smooth communication between the vertical drain passages and the horizontal drain passages can be guaranteed. The field solidified soil is used as the material for surcharge preloading, so that construction efficiency is improved, and the transport cost of surcharge materials is saved.

Description

technical field [0001] The invention relates to a construction method for rapid drainage and rapid consolidation of silt in a storage yard, which belongs to the field of resources and environment. Background technique [0002] In order to improve the water quality of lakes, my country's Taihu Lake, West Lake, Chaohu Lake, Dianchi Lake, Dongshan Lake, Luhu Lake and other lakes are carrying out large-scale dredging projects. At the same time, some urban rivers, navigable rivers and small rural rivers have also carried out dredging projects for the purpose of improving water quality, smooth waterways, and guaranteeing flood discharge and water delivery capacity. At present, domestic lake dredging and river channel dredging silt are mainly stored in the storage yard first, and then the storage yard foundation treatment for the purpose of improving the bearing capacity is carried out, or the solidification treatment is used as soil material for modification. [0003] The vacuum ...
