Embodiment 1

[0049] Please refer to the following Figure 3A ~ Figure 3D , is an implementation process of an application example of the present invention.

[0050] Please refer to Figure 3A , which is the original state of the field without any action. There is no need to deal with the muddy soil layer on the soil layer, and the upper layer is fluid mud or floating mud that is dredged, that is, the extremely soft mud that the present invention will solve.

[0051] Please refer to Figure 3B , lay the bamboo mesh frame shown in Figure 3 in the extremely soft silt, and then lay the geotextile on the upper surface of the bamboo mesh frame, and further lay the water-collecting sand cushion on the geotextile, from the water-collecting sand cushion to the Vertical drainage bodies are inserted below, and these vertical drainage bodies extend to the position close to the soil layer that does not need to be treated; and the pumping pipes are buried from the outside to the water-collecting sand...

Abstract

The invention discloses a quick strengthening method of extremely soft sludge. The method lays out an area of a to-be-constructed site firstly according to a project plan and comprises the following steps: (1), carrying out bamboo web frame-type reinforcement on a sludge soil layer on an extremely soft sludge surface layer; (2), laying geotextile on the upper surface of a bamboo web frame and further laying a water-collecting sand bed on the geotextile; (3), inserting a vertical water drain body downwards from the water-collecting sand bed; (4), burying a water-pumping pipeline from the outside to the water-collecting sand bed and extending the pipeline to an extremely soft sludge layer; (5), filling soil on the surface of the water-collecting sand bed time after time and carrying out dynamic compaction after filling soil every time; and (6), discharging extruded water through the water-pumping pipeline after finishing dynamic compaction every time, and quickly dissipating excess pore pressure of sludge soil caused by soil filling load and dynamic compaction load. Compared with the conventional methods, the quick strengthening method can greatly shorten a construction period and also reduce construction cost.

Description

technical field [0001] The invention relates to an engineering method for land reclamation projects, in particular to a method for quickly reinforcing extremely soft silt that is consolidated by adopting reinforced multi-stage composite force drainage. Background technique [0002] In recent years, with the rapid development of my country's economic construction and the increasing shortage of land resources, large-scale land reclamation projects and dock yard projects have been vigorously carried out in my country's coastal zone. Since many coastal zones in our country are silting coasts, the materials for land reclamation are floating and fluid silt, and the underlying layer is thick and extremely soft silt-like soil. After the site is filled, it cannot become usable in a short period of time. Rapid processing of such sites is an urgent need for economic construction. [0003] In the prior art reclamation projects, most of the projects are to lift the extremely soft flow s...
