Efficient urban regional underground water level change test system construction method

Abstract

The invention discloses a high-efficiency urban regional underground water level change test system construction method, which is characterized in that in an urban subway station foundation pit construction process, foundation pit construction monitoring work is tightly combined, and station foundation pit construction short-term monitoring needs are combined in a subway special protection area range red line around a station; a plurality of long-term water level monitoring holes are preset in key parts around a foundation pit to test the water level change of a key aquifer of a site, and a wireless data acquisition instrument is mounted in an equipment area in a station to realize real-time data acquisition, so that test data of distributed stations in a city are summarized to a plurality of monitoring stations through the internet, and the monitoring stations are used for monitoring the water level change of the distributed stations in the city. Therefore, long-term effective observation of the underground water level change condition in the urban area range is realized, and subway operation protection and urban disaster prevention and reduction work are served. Urban subway construction waste water level test holes are fully utilized, standard cone construction can be conducted in combination with station foundation pit construction, the construction cost is saved, and the method can be widely used and popularized in riverside and coastal cities.
