Convenient water collecting and draining device for deep foundation pit
The invention relates to a convenient water collecting and draining device for a deep foundation pit, and belongs to the technical field of civil engineering. The convenient water collecting and draining device for the deep foundation pit comprises a concrete cushion layer, wherein the concrete cushion layer is poured above foundation pit soil, a water collecting pit is arranged in the foundation pit soil, a water collecting barrel is arranged in the water collecting pit, a plastic light pipe is arranged on the upper part of the water collecting barrel, an upper end opening of the plastic light pipe is not lower than the upper surface of the concrete cushion layer, and the lower part of the plastic light pipe is connected with a hollow-out barrel-shaped grating; the lower end of the barrel-shaped grating is connected with a conical bottom which is of a hollow structure, and the center of the conical bottom is sunken downwards; a hollow-out water pump placing bearing platform is arranged on the lower part of an inner cavity of the barrel-shaped grating, and a hollow-out bottom bearing platform is arranged at a lower end opening of the barrel-shaped grating; a water stop ring embedded in the concrete cushion layer is arranged on the periphery of the upper part of the plastic light pipe, and a plurality of drainage openings are formed in the circumference of the plastic light pipe. According to the convenient water collecting and draining device for the deep foundation pit, large silt in the foundation pit can be effectively isolated, seepage water is effectively filtered out, the service life of a water pump is prolonged, the drainage efficiency is improved, the maintenance cost is reduced, and the foundation pit is kept dry when the geological condition is silty clay.
本发明涉及一种深基坑便捷式集水、排水装置,属于土木工程技术领域。包括混凝土垫层，混凝土垫层浇筑于基坑土的上方，基坑土中设有集水坑，集水坑中置有集水筒，集水筒的上部为塑料光管，塑料光管的上端口不低于混凝土垫层的上表面，塑料光管的下方连接有镂空的筒状格栅。筒状格栅的下端连接有锥形底部，锥形底部为空心结构且中心向下凹陷。筒状格栅的内腔下部设有镂空的水泵放置承台，下端口设有镂空的底部承台。塑料光管的上部外周设有嵌于混凝土垫层中的止水环。塑料光管的圆周上设有多个引流口。本发明能够有效隔离基坑中的大块泥沙，将渗水有效滤出，延长水泵寿命，提高排水效率，降低维护成本，在地质情况为粉质黏土时保持基坑干燥。
