Self-filtering type anti-blocking double-layer downcast tube well, preparation method and construction method
The invention discloses a self-filtering type anti-blocking double-layer downcast tube well, a preparation method and a construction method, and belongs to the technical field of building construction. The downcast tube well comprises a double-layer concrete tube, the double-layer concrete tube comprises an outer-layer tube, an inner-layer tube and a filter material layer, the filter material layer is filled between the outer-layer tube and the inner-layer tube, and a bottom sealing layer is arranged at the bottom of the double-layer concrete tube. And a broken stone hardcore is arranged below the bottom sealing layer. The outer-layer pipe, the inner-layer pipe and the bottom sealing layer are made of pervious concrete, and the pervious concrete is prepared from, by mass, 20-35 parts of a cementing agent, 1550-1650 parts of gravel, 250-350 parts of cement, 5.4-7.7 parts of a high-efficiency water reducing agent and 115-122 parts of water. The dewatering tube well has high strength and high water permeability, and the purposes of foundation pit dewatering and underground water collection and cyclic utilization are effectively achieved.
本发明公开了一种自滤型防堵塞双层降水管井、制备方法及施工方法，属于建筑施工技术领域。所述降水管井包括双层混凝土管，所述双层混凝土管包括外层管、内层管和滤料层，所述滤料层填充在外层管和内层管之间，所述双层混凝土管底部设有封底层。所述封底层下设有碎石垫层。所述外层管、内层管和封底层由透水混凝土制得，所述透水混凝土的质量份数由20～35份胶结剂、1550～1650份碎石、250～350份水泥、5.4～7.7份高效减水剂、115～122份水组成。本发明的降水管井兼具高强度和高透水性能，有效实现基坑降水和地下水收集循环利用的目标。
