Horizontal drainage and quick consolidation method for reinforcing new hydraulically filled sludge and pipe-laying equipment thereof

Abstract

The invention discloses a horizontal drainage and quick consolidation method for reinforcing new hydraulically filled sludge and pipe-laying equipment thereof, wherein a plurality of layers and a plurality of rows of horizontal drainage channels are laid in the sludge, and both the interlayer spacing and the spacing in rows are approximately between 60 and 80 centimeters so as to form a high-density under-sludge drainage network; and the network is hermetically connected with hermetical ground horizontal drainage pipes, is connected with jet drainage devices and performs air suction and pumping, so that the new hydraulically filled sludge can be quickly reinforced within a short period. The equipment for realizing the method comprises a horizontal pipe-laying machine, an undercarriage, a shifter which can move on water or the sludge, and the like. The construction method and the equipment solve the problem that personnel and equipment cannot operate on the new hydraulically filled sludge, simultaneously can quickly and conveniently reinforce the new hydraulically filled sludge, has low manufacturing cost, and is environment-friendly, safe and reliable,, and the method solves the problems of quick hydraulic fill and continent making and reinforcement of river beds and dam beds.

Description

technical field [0001] The invention relates to a foundation treatment equipment and method, in particular to a horizontal drainage rapid consolidation method and pipe laying equipment for the reinforcement of newly dredged silt. Background technique [0002] With the development and construction of my country's coastal areas, the technology and scale of dredging land reclamation are also developing rapidly, but it takes one year or even several years of natural settlement time for the dredged land reclamation to be consolidated to meet the requirements of human and machine construction. The level of engineering construction cannot meet the requirements of early construction and early production. [0003] The existing technology usually uses underground plastic drainage boards to be vertically driven into the soft soil, a sand cushion layer is laid on the ground, drainage pipes are buried horizontally in the sand layer, and the connected vacuum jet device is used to pump air ...

AI Technical Summary

Problems solved by technology

However, the problem in the prior art is that the newly filled mud is in a superfluid plastic state, with a moisture content above 100%, and the man-machine operation has to wait for half a year or even longer, or a few meters of sandy soil needs to be filled on it.

The current preloading reinforcement technology requires first laying sand, laying film and sealing it before starting preloading. However, the newly dredged fill silt is too soft and cannot meet the load conditions of manual large-scale sand laying and film laying operations. Therefore, the new dredged land reclamation project is After the dredging and filling is completed or wait for natural consolidation, about half a year to a year, or take the temporary surface layer of dredging and filling sand layer or artificial filling of mountain soil, etc., which delays the time and construction period

[0004] In the past, there was another technique of laying drainage boards on the bottom of the pit before filling, and then erecting vertical drainage pipes on the horizontal drainage boards (with a spacing of 1m×1m); The horizontal drainage channel is 3m or even 10m above the surface of the dredged silt, and its drainage consolidation range is very small, generally only 0.8m of the bottom layer can be consolidated, while the upper and bottom silt can only rely on vertical drainage pipes, which stand upright out of thin air. Most of the vertical drainage in the dredging and filling process is washed down or disturbed, so that it is impossible to ensure uniform and effective drainage and consolidation
