混凝土挡土墙工程施工技术
Construction Technology of Concrete Retaining Wall
1、基槽挖土方:本工程挖基槽土方采用挖掘挖机及人工配合进行开挖。挖基配合墙体施工分段进行,先测量放线,定出开挖中线及边线,起点及终点,设立桩标,注明高程及开挖深度,用1m3反铲挖掘机开挖,多余的土方装车外运弃土。在施工过程中,应根据实际需要设置排水沟及集水抗进行施工排水,保证工作面干燥以及基底不被水浸。
1. Excavation of foundation trench: Excavation of foundation trench in this project is carried out by excavator and manual cooperation. The foundation excavation is carried out in stages with wall construction. First, the laying-out line is measured, the middle line and side line of excavation are determined, the starting point and end point are determined, the pile mark is set up, the elevation and excavation depth are indicated, the excavation is carried out with a 1 m3 backhoe excavator, and the surplus earth is loaded outside the truck to transport the discarded soil. In the construction process, drainage ditches and catchment resistance should be set up according to the actual needs to carry out construction drainage, so as to ensure that the working face is dry and the base is not immersed in water.
2、地基处理:当挖基发现有淤泥层或软土层时,盖土网 防寒布 麻绳 油麻绳 麻刀 沥青麻绳 静压造型线 自动浇注机 铸铁拍门 钢制拍门 玻璃钢拍门需进行换土处理,报请监理工程师及业主批准后,才进行施工。
2. Foundation treatment: When a silt or soft soil layer is found in the excavated foundation, soil replacement treatment is required, which is submitted to the supervisory engineer and the owner for approval before construction is carried out.
