Water-rich sand layer pump house precipitation method
The invention discloses a water-rich sand layer pump room dewatering method which comprises the following steps: arranging a plurality of well point pipes with a first preset depth along the periphery of a pump room area, and discharging underground water in a first preset depth range; a pump room foundation pit with the first preset depth is excavated, after supporting system construction is conducted on the side wall of the pump room foundation pit, a plurality of well point pipes with the second preset depth are arranged on the side wall of the pump room foundation pit in a driving mode, included angles are formed between the well point pipes and the pump room wall, and underground water within the second preset depth range is discharged; a pump room foundation pit with a second preset depth is excavated, after supporting system construction is conducted on the side wall of the pump room foundation pit, a plurality of well point pipes with a third preset depth are arranged on the side wall of the pump room foundation pit in a driving mode, and underground water within the third preset depth range is discharged; the steps are repeated until the pump house is excavated; by means of layered precipitation and layered excavation, precipitation and construction are conducted synchronously, the construction progress is accelerated, and the safety problem in the construction process is solved.
本发明公开了一种富水砂层泵房降水方法，包括以下步骤：沿泵房区域四周打设第一预设深度的若干井点管，排出第一预设深度范围内的地下水；开挖第一预设深度的泵房基坑，并在泵房基坑的侧壁上进行支护体系施工后，在泵房基坑的侧壁上打设第二预设深度的若干井点管，井点管与泵房壁成夹角设置，排出第二预设深度范围内的地下水；开挖第二预设深度的泵房基坑，并在泵房基坑的侧壁上进行支护体系施工后，在泵房基坑的侧壁上打设第三预设深度的若干井点管，排出第三预设深度范围内的地下水；重复上述步骤，直至泵房开挖完毕；本发明通过分层降水，分层开挖的方式，使得降水和施工同步进行，不仅提升了施工进度，还降低了施工过程中的安全问题。
