Embodiment

[0026]This embodiment is based on the inland waterway project of Yancheng Port Binhai Port Area, which has been officially approved by the Provincial Development and Reform Commission in March 2013, and is now gradually entering the construction phase. The coastal port area of ​​Yancheng Port is an important node in the spatial layout of the “three poles, one belt, and multiple nodes” of coastal development in Jiangsu. The port dredging channel project in the Binhai Port Area shall be rectified according to the IV level standard, and corresponding navigable buildings shall be constructed, including the Yunyanhe Ship Lock and the Binhai Ship Lock. The Binhai Ship Lock is located on the south side of the abandoned Yellow River culvert in the Shugang Channel in the Binhai Port Area, and the Yunyan River Ship Lock is located at the intersection of the Zhongshan River and the Yunyan River in Toujin Village, Binhuai Town. According to the "Engineering Geological Investigation Report...

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-water content silt and newly blown fill soil, and belongs to the technical field of dredging ultra-soft soil. Background technique [0002] Drainage consolidation method is an important soft soil foundation treatment method. This method shortens the distance that water is drained by seepage of the soil body by arranging vertical and horizontal drainage bodies in the soft soil, and combines vacuum or stacking methods to make the water flow. The water in the soil flows out of the soil under the action of negative pressure or excess 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 the horizontal drainage body and the vertical drainage body is the key factor affecting the treatment effect. At present, the commonly used materials for vertical drainage bodies are sand or gravel piles, sand...
