Construction method of newly-built river channel anti-seepage air closing structure
The invention provides a construction method of a newly-built riverway seepage-proofing and air-closing structure. The construction method comprises the following steps of riverway foundation cleaning, inner slope inverted filter structure construction, stabilized soil graded hydraulic reclamation, stabilized soil maintenance, riverway excavation, slope protection plastic steel sheet pile driving and slope protection surface construction. The problems that the water content is high, the bearing capacity is low, the excavation difficulty is large, and the seepage-proofing and air-closing effect of a newly-built river channel is poor when seabed mucky soil is adopted as river channel seepage-proofing and air-closing soil are mainly solved. According to the method, the undisturbed mucky soil is improved by adopting a mode of hydraulic reclamation of seabed silt solidified soil, so that the performance of the mucky soil is improved, the requirements of anti-seepage and air closing functions are met, meanwhile, the river channel excavation and local material utilization are facilitated, and the construction cost is reduced; a row of plastic steel sheet piles are arranged on the inner slope of the riprap embankment along a river channel, a riprap embankment water seepage channel is cut off, and the anti-seepage and air closing effects are further ensured.
本发明提供了一种新建河道防渗闭气结构的施工方法，包括如下步骤：河道清基、内坡倒滤结构施工、固化土分级吹填、固化土养护、河道开挖、护坡打设塑钢板桩和护坡护面施工。主要解决采用海底淤泥质土作为河道防渗闭气土时含水率高、承载力低、开挖难度大，新建河道防渗闭气效果不佳等难题。通过采用吹填海底淤泥固化土的方式，对原状淤泥质土进行改良处理，改善淤泥质土性能，满足防渗闭气功能要求的同时便于河道开挖，就地取材，减少了施工成本；在抛石堤内坡沿河道打设一排塑钢板桩，截断抛石堤渗水通道，进一步确保防渗闭气效果。
