Pipeline groove dewatering green construction method and assembly type pipe well section for dewatering
The invention discloses a green construction method for dewatering of a pipeline groove. The construction sections, from low to high, of the pipeline groove are the first construction section, the second construction section to the last construction section in sequence. P, N and M are natural numbers, N > = 6, P is the serial number of the last construction section, and P > M > = 1; each construction section comprises first to seventh operations which are executed in sequence, and the first to seventh operations comprise primary excavation, well drilling dewatering and drainage, secondary excavation, pipeline installation, primary backfill, tube well dismantling and gravity recharge and secondary backfill; 6 > = L > = 1; drilling a well to pass through a slope toe on one side of the groove bottom of the pipeline groove; after the Lth operation of the Mth construction section is completed, the (L + 1) th operation of the Mth construction section and the Lth operation of the (M + 1) th construction section are conducted at the same time; after the seventh operation of the Mth construction section is completed, the seventh operation of the (M + 1) th construction section is carried out; after the seventh operation of the Pth construction section is completed, all construction is completed; and in the second operation to the fifth operation of the Nth construction section, water is drained into underground water of the (N-5) th construction section to achieve recharging. The invention further discloses the assembly type tube well section for dewatering adopted in the second operation. High energy consumption caused by slope top well drilling and precipitation is avoided, the water pumping position is closer to the precipitation center, in-situ recharge is achieved, energy consumption is greatly reduced, the water pumping amount is reduced on the premise that the same precipitation target is achieved, the influence on underground water and the surrounding environment is greatly reduced, and water resources and the surrounding environment are protected.
本发明公开了一种管道沟槽降水绿色施工方法，以管道沟槽由低到高的施工段依次为第一、第二直到最后一个施工段；P、N和M为自然数，且N≥6，P为最后一个施工段的序号，P＞M≥1；每一施工段均包括按顺序执行的第一至第七作业，分别是一次开挖、钻井降水排水、二次开挖、管道安装、一次回填、管井拆除及重力回灌，以及二次回填；6≥L≥1；钻井通过管道沟槽的槽底一侧坡脚；第M施工段的第L作业完成后，同时进行第M施工段的第L+1作业以及第M+1施工段的第L作业；第M施工段的第七作业完成后，进行第M+1施工段的第七作业；第P施工段的第七作业完成后，完成全部施工；第N施工段的第二作业至第五作业中，水排至第N－5施工段的地下水中实现回灌。本发明还公开了第二作业中采用的降水用装配式管井段。本发明避免了坡顶钻井和降水带来的高能耗，泵水位置更靠近降水中心，实现了原位回灌，大幅降低了能耗，在实现相同降水目标的前提下减少了泵水量，大幅降低了对地下水以及周边环境的影响，保护了水资源以及周边环境。
