Construction method applied to close-packed imitation timber pile revetment of soft soil river channel revetment
The invention relates to a construction method applied to a close-packed imitation wood pile revetment of a soft soil riverway revetment. The construction method comprises the following steps: constructing a cofferdam in a measuring and positioning area of close-packed imitation wood piles; according to the revetment linear measurement, positioning and applying first interval section close-packed imitation wood piles; digging tie bar belt grooves according to the designed number of spaced piles, and paving filler as a cushion layer; tiepiece belts are laid according to the spaced pile sections; paving, compacting and backfilling the lacing wire belt groove by using a proper filler; a first interval section of imitation wood piles is constructed, a tie piece belt groove is excavated, the last section is in lap joint, a tie piece belt of the section is laid, and filling, paving and compacting are conducted; and repeating the construction until the end. According to the construction method, the phenomenon that the formed piles are prone to inclining and deforming in the riverbed direction due to the physical and mechanical characteristics of soft soil texture is avoided, the linear quality of revetment close-packed wood-imitating pile revetment construction is guaranteed, meanwhile, the overall rigidity of traditional concrete wood-imitating piles and wood piles is improved, and the construction efficiency is improved. And the process weakness that the concrete imitation wood pile is easy to be extruded and broken by soft soil due to overlarge slenderness ratio caused by lengthening the concrete imitation wood pile is avoided.
本发明是一种应用于软土河道驳岸密排仿木桩护岸施工方法，包括在密排仿木桩的测量定位区域施作围堰；根据驳岸线形测量定位施打第一间隔段密排仿木桩；根据设计间隔桩数和挖掘拉筋带槽，并铺入填料作为垫层；按间隔桩段铺设拉筋带；使用合适的填料摊铺、压实和回填拉筋带槽；施打下一间隔段仿木桩，开挖拉筋带槽并搭接上一段铺设本段拉筋带，填料、摊铺和压实；重复施工直至结束。本施工方法解决了因软土土质的物理力学特性导致成桩易向河床方向倾斜和变形的现象，保证了驳岸密排仿木桩护岸施工的线性质量，同时还提升了传统砼仿木桩、木桩的整体刚性，避免了因加长砼仿木桩引起的长细比过大易受软土挤压折断的工艺弱点。
