Dismantling method for current rain and sewage confluence square ditch
The invention relates to a method for dismantling a current rain and sewage confluence square ditch, which is used for breaking an existing first rain water square ditch in a foundation trench, the first rain water square ditch is at least partially embedded in a rock-soil body below a main road, and the method at least comprises the following steps: respectively constructing a steel sheet pile support and a hanging net anchor-shotcrete support on one side of the foundation trench facing a first direction and a second direction; the foundation trench is excavated to the top of the first rainwater square ditch, and a hole is formed in a top cover plate of the first rainwater square ditch; the first rainwater square ditch is filled with a concrete mixture through the hole; and when filling of the concrete mixture is completed and the coagulation strength of the concrete mixture reaches a threshold value, chiseling is conducted from a top cover plate of the first rainwater square ditch, and excavation is continuously conducted to the bottom of the foundation trench.
本发明涉及一种现况雨污合流方沟拆除方法，用于破除基槽内的既有第一雨水方沟，该第一雨水方沟至少部分地嵌入于主道路下方岩土体，该方法至少包括：分别在基槽朝向第一方向和第二方向的一侧施做钢板桩支护和挂网锚喷支护；开挖基槽至第一雨水方沟顶部，并于第一雨水方沟顶部盖板处破洞；通过该洞口向第一雨水方沟内部填充混凝土拌和料；待混凝土拌和料填充完毕且其凝结强度达到阈值之时，从第一雨水方沟顶部盖板开始凿除，并持续开挖至基槽槽底。
