Stereoscopic network drainage for accelerating water drainage consolidation velocity of hydraulic mud fill sludge

Abstract

The invention relates to a three-dimensional network drainage device for accelerating the consolidation speed of the drainage of filled silt. The device is composed of a ripple pipe, a plastic drainage plate and a pumping-drainage pipe, water inlet holes are evenly distributed on the side wall of the ripple pipe, geo-filter cloth is wrapped at the outside thereof, medium-coarse sand with 50cm to 60cm is filled at the bottom part of the ripple pipe, the plastic drainage plate and the ripple plate are connected by adopting the geo-filter cloth for binding, the lower part of the pumping-drainage pipe is processed into a perforated pipe to be inserted in the medium-coarse sand at the bottom part of the ripple pipe, the upper part is connected with an outer pumping-drainage system by a connector to form the three-dimensional network drainage device; a drainage pipe network in the silt filling and the consolidation processes can be connected with an outer pumping-drainage device, thereby realizing the whole process of drainage and improving the drainage efficiency and the speed.

Description

technical field [0001] The invention relates to a three-dimensional network drainage device for accelerating the drainage and consolidation speed of dredging and filling silt in soil mechanics engineering, so as to accelerate the drainage and consolidation speed of silt so as to achieve the purpose of accelerating the drainage and consolidation of deposited silt. Background technique [0002] At present, when mud is used for land reclamation at home and abroad, the cofferdam is generally built first, and then the mud-water slurry is blown and filled into the cofferdam with the dredging equipment, so that the soil particles are deposited in the cofferdam under the action of its own weight. If enough soil particles are deposited in the cofferdam, it is necessary to continuously fill the cofferdam with mud-water slurry. In order to speed up the deposition rate of soil particles and increase the deposition amount of soil particles, it is generally used to blow and fill mud-water...

AI Technical Summary

Problems solved by technology

These accelerated consolidation methods are all to set up drainage channels in the deposited silt after the filling is completed, and the drainage channels added inside the silt are all vertical, and there is no horizontal drainage channel inside the silt. The square drainage channels are mainly concentrated on the surface of the silt. Due to the low permeability coefficient of the silt, the simple vertical drainage channels often make the drainage and consolidation time of the deposited silt longer, making the drainage efficiency lower.
