Divided dewatering dry excavation construction method for underground connection wallboard pile wharf
The invention provides an underground diaphragm wallboard pile wharf zoning dewatering dry excavation construction method which comprises the working procedures of harbor basin zoning, reserving of multiple water retaining cofferdams, layered dewatering, foundation pit layered excavation, water retaining cofferdam dismantling and the like. Compared with a traditional dredging technology, the quality is controllable, and the method is economical and environmentally friendly; fewer dewatering wells can be used by regional excavation, so that the economical efficiency is better; and the construction method is particularly suitable for digging-in harbor basin construction of a water-rich strong-permeable stratum with a large length.
本发明提供一种地连墙板桩码头分区降水干开挖施工方法，包括港池分区、预留多道挡水围堰、分层降水、基坑分层开挖、挡水围堰拆除等工序，与传统疏浚工艺相比，质量可控、经济环保，与港池采用整体干开挖工艺相比，分区域开挖可使用更少的降水井，经济性更好；特别适用于长度较大的富水强透水地层的挖入式港池施工。
