Sunken prefabricated inspection well and underground construction method thereof
The invention discloses a sunken prefabricated inspection well and a underground construction method thereof. The sunken prefabricated inspection well comprises a top plate, a bottom plate and a valve well shaft, wherein the top plate and the bottom plate are fixedly arranged and plugged on the end faces of two axial openings of the valve well shaft, an annular blade foot is integrally manufactured at an opening in the bottom of the valve well shaft, a plurality of holes are formed in the lower portion of the valve well shaft in the radial direction, and a bracket extending in the radial direction is integrally manufactured on the inner wall of the valve well below the hole. The underground construction method for the prefabricated inspection well comprises the steps that firstly, a valve well shaft is prefabricated in a factory and vertically hoisted to a preset underground position; secondly, a base plate is laid at a top opening of the valve well shaft, and pressure equipment is erected at the axis position of the top face of the base plate; thirdly, the valve well shaft is pressed to the preset buried depth, and then muck in the valve well shaft is excavated; and fourthly, a concrete bottom plate is poured, and a concrete top plate is installed. The prefabricated inspection well is convenient to use, simple to construct and small in influence on traffic and daily life of nearby buildings and human beings.
一种下沉式预制检查井，包括顶板、底板及阀门井井筒，其中顶板及底板分别固设并封堵在阀门井井筒两个轴向开口的端面上；阀门井井筒底部开口处一体制出有环形刃脚，且阀门井井筒的下部径向开设有多个洞口；洞口下方的阀门井内壁上一体制出有径向延伸的牛腿。预制检查井的地埋施工方法，包括：步骤一，在工厂预制好阀门井井筒并垂向吊装至预定地埋位置；步骤二，在阀门井井筒的顶部开口处铺设垫板，并在垫板顶面轴心位置架设压力设备；步骤三，将阀门井井筒压至预定地埋深度，而后开掘阀门井井筒内部的渣土；步骤四，浇筑混凝土底板，并安装混凝土顶板。该预制检查井使用方便，施工简单，对临近构建筑物以及人类的交通和日常生活影响较小。
