Embodiment

[0026]This embodiment is based on the inland river dredging channel project in Binhai Port Area of ​​Yancheng Port, which was officially approved by the Provincial Development and Reform Commission in March 2013, and is currently gradually entering the construction stage. The Binhai Port Area of ​​Yancheng Port is an important node in the spatial layout of "three poles, one belt and multiple nodes" in the coastal development of Jiangsu. As an important part of the port collection and distribution system, the inland river channel plays an important role in the development of the Binhai Port Area. The port dredging channel project in the Binhai Port Area will be renovated in accordance with Class IV standards, and corresponding navigable structures will be built, including two ship locks for Yunyan River and Binhai Ship Lock. The Binhai ship lock is located on the south side of the waste Yellow River culvert of the dredging channel in the Binhai port area, and the Yunyanhe ship l...

Abstract

The invention relates to a drainage system used for drainage consolidation of high-water-content sludge and new dredger fill and belongs to the technical field of ultra soft soil. The drainage system comprises straw blankets and a straw roll, wherein the straw blankets are laid on the sludge or the new dredger fill, and the straw roll is inserted into the sludge or the new dredger fill. The straw blankets and the straw roll are fixedly connected to form the whole drainage system. The straw blankets are blanket type objects formed by weaving straw. The straw roll is a roll type object formed in the mode that a geotechnical cloth bag is wrapped on the straw. The novel drainage system can solve the problem of straw pollution in agricultural production, lower the construction cost for drainage consolidation of the ultra soft soil such as the high-water-content sludge and the new dredger fill and substantially improve the construction efficiency.

Description

technical field [0001] The invention relates to a drainage system for draining and consolidating high-moisture silt and newly dredged fill, and belongs to the technical field of dredging supersoft soil. Background technique [0002] Drainage consolidation method is an important soft soil foundation treatment method. This method shortens the distance for water to be drained by soil seepage by arranging vertical and horizontal drainage bodies in soft soil, and combined with vacuum or heap loading to make The water in the soil flows out of the soil under the action of negative pressure or excess static pore pressure, so as to achieve the purpose of consolidating the soil and increasing the strength of the soil. In this method, the layout of horizontal drainage body and vertical drainage body is the key factor affecting the treatment effect. At present, materials commonly used for vertical drainage bodies include sand or gravel piles, sand bags, plastic drainage boards, etc., w...
