Subway station deep foundation pit excavation construction method
The invention discloses a subway station deep foundation pit excavation construction method, wherein the upper portion of an excavated foundation pit is a sandy gravel stratum, and the lower portion of the excavated foundation pit is a mud rock stratum. The method includes the steps of 1, precipitation construction, wherein precipitation construction is conducted on the sandy gravel stratum through a precipitation well and 2, foundation pit excavation, wherein the foundation pit excavation includes the following steps of foundation pit partition and foundation pit earthwork excavation; the excavated foundation pit is divided into a plurality of small foundation pit bodies to conduct excavation respectively; the small foundation pits comprise first foundation pit bodies and second foundation pit bodies; excavation is conducted on the divided small foundation pit bodies; an open-cut method is adopted for the first foundation pit bodies and the second foundation pit bodies; the first foundation pit bodies are supported by fender posts, reinforced concrete supports and steel pipe inner supports; the second foundation pit bodies are supported by the fender posts, pre-stressed anchor cables and the steel pipe inner supports. The subway station deep foundation pit excavation construction method is simple in step, reasonable in design, convenient to construct, faster in construction process, good in construction effect and capable of easily conveniently and fast to finish deep foundation pit excavation construction process, and the influences on the surrounding environment by the excavation construction process are smaller.
