Rapid dewatering device suitable for sandy soil stratum
The invention belongs to the technical field of foundation pit drainage, and particularly relates to a rapid dewatering device suitable for a sandy soil stratum, which comprises a drainage main pipe, a plurality of drainage branch pipes, a plurality of horizontal pipes, a spiral drill cylinder, a drilling assist device and a vacuum pump, drainage branch pipes are inserted into the periphery of a structure in a water area of a sand soil stratum in advance, and vacuum pump dewatering is carried out, so that it can be ensured that the water level in a pit is lowered within the shortest time, and the drying requirement during construction is met; the drainage branch pipe and the spiral drill barrel matched with the rapid dewatering device enable the pipeline to be inserted simply and efficiently, independent guide holes are not needed, the pumping and drainage speed is concentrated, the dewatering effect can be effectively completed in a small-range foundation pit, and the rapid dewatering device has the effects of being convenient and rapid to construct, low in risk and low in cost; the problems that the water level of an existing sandy soil stratum small-range area (such as a bearing platform and a water collecting well) cannot be lowered, and effective construction cannot be achieved are solved, the construction progress is accelerated, and a certain quality optimization result and economic benefits are obtained.
本发明属于基坑排水技术领域，具体涉及一种适用于砂土地层的快速降水装置，包括排水主管、多个排水支管、多个水平管、螺旋钻筒、钻进辅助器和真空泵；通过在砂土地层有水区域、结构四周提前插入排水支管，并进行真空泵降水，从而可以确保在最短时间内降低坑内水位，满足施工时的干燥要求；本快速降水装置配套的排水支管和螺旋钻筒使管道插入简单、高效，无需单独引孔，且抽排速率集中，能够在小范围基坑内有效完成降水效果，有施工便捷、快速，且风险及成本较低的效果，以解决现有砂土地层小范围区域(如承台、集水井)水位无法下降，无法有效施工的问题，加快了施工进度，取得了一定的质量优化结果和经济效益。
