Construction method for mechanically excavating sheet-pile wall
The invention belongs to the technical field of mechanical excavation, and particularly relates to a construction method for mechanically excavating a sheet-pile wall. The problems that in the excavating process of a large-size rectangular pile based on an existing manual hole digging mode, the work efficiency is low, the safety coefficient is low, and the cost is high are solved. The method comprises the following steps that S100, hole opening lofting is conducted according to the design position of the sheet-pile wall, and construction lofting is conducted on the position of a locking opening; S200, locking opening construction is carried out; S300, the sheet-pile wall is excavated; S400, steel bar binding of the sheet-pile wall is conducted according to the principle of proximity; and S500, concrete pouring is conducted. The method is simple and efficient, the safety risk of the manual hole digging pile is reduced, and the method is worthy of popularization.
本发明属于机械开挖技术领域，具体是一种机械开挖桩板墙施工方法。解决了现有人工挖孔方式进行大尺寸矩形桩开挖过程中工效缓慢，安全系数低，成本高等问题，包括以下步骤。S100～按照桩板墙设计位置进行孔口放样，对锁口的位置进行施工放样。S200～进行锁口施工；S300～进行桩板墙开挖；S400～采取就近原则进行桩板墙钢筋绑扎。S500～进行混凝土灌注。本发明简单高效，更降低了人工挖孔桩的安全风险，值得推广。
