Rock foundation low-point precipitation construction process and construction device
The invention belongs to the technical field of foundation construction, and discloses a rock foundation low-point precipitation construction process and a construction device. The construction process comprises the steps that in the earth excavation stage, a well is drilled in the position needing precipitation, a steel pipe with holes is buried in the drilled well, and a water pipe is arranged in the steel pipe with holes and connected with a self-priming pump; a graded broken stone layer, a plastic film layer, a cushion layer, a waterproof roll layer, a waterproof additional layer and a foundation reinforcing mesh layer are sequentially arranged upwards from the elevation of the lowest point of the rock, and a sealing piece is arranged in the foundation reinforcing mesh layer; and the water pipe of the self-priming pump is detached before concrete pouring, the steel pipe with the holes is sealed through the sealing piece, and concrete pouring is conducted after sealing. According to the construction process, by arranging the steel pipe with the holes and the sealing piece, the water level in the steel pipe with the holes is lowered through the self-priming pump before concrete pouring, the top of the steel pipe with the holes is sealed through the sealing piece before pouring, concrete pouring is rapidly conducted, reliability is high, cost is low, and construction efficiency and construction quality can be improved easily.
本发明属于地基基础施工技术领域，公开了一种岩石地基低点降水施工工艺和施工装置，施工工艺包括在土方开挖阶段，在需降水位置钻井，在钻井内埋设带孔钢管，并在带孔钢管内设置水管并连接自吸泵的步骤，还包括在岩石最低点标高处开始向上依次设置级配碎石层、塑料薄膜层、垫层、防水卷材层和防水附加层以及基础钢筋网层的步骤，基础钢筋网层内设置密封件；在混凝土浇筑前拆除自吸泵的水管，通过密封件密封带孔钢管，密封后进行混凝土浇筑。本发明通过设置带孔钢管和密封件，在混凝土浇筑之前通过自吸泵降低带孔钢管内水位，浇筑前通过密封件密封带孔钢管顶部并快速进行混凝土浇筑，可靠性高且成本低，利于提高施工效率和施工质量。
