Abstract

The invention provides a method for detecting the water pressure of peat soil soft soil foundation. The method for detecting the water pressure of the peat soil soft soil foundation comprises the steps of a, drilling a borehole on the ground by drilling equipment; b, installing a vertical pipe water pressure gauge in the borehole so as to be used for monitoring the water level of a pressure measuring pipe; c, elevating the water level with a water pressure indicator, wherein the elevation is the water pressure. In the step b, the installation method of the vertical pipe water pressure gauge further comprises the steps of b1, installing a lifting pipe and a filtering nozzle in the borehole in a combined manner; b2, filling a filtering layer around the filtering nozzle; b3, filling bentoniteand bentonite cement slurry above the filtering layer; and b4, installing a protective sleeve on the top of the borehole. The detection method provided by the invention is applicable to the filling of the peat soil soft soil foundation with complex geological conditions, and aims to solve a problem of difficult water pressure monitoring of the traditional water pressure gauge.

Description

technical field [0001] The invention relates to the technical field of roadbed engineering, in particular to a method for detecting hydraulic pressure of peat soil soft soil foundation. Background technique [0002] At present, among the detection devices used for ground subgrade filling in general terrain, there are existing domestic subgrade water pressure gauges for monitoring, and there are also vibrating wire pore water pressure gauges for monitoring, but these two kinds of water pressure gauges have limitations. Geologically complex terrain makes monitoring more difficult. For example, for subgrade filling of peat soil soft soil, the geological conditions of peat moss soft soil are complex, the stability of subgrade slope is poor, and it is difficult to monitor the movement state of groundwater and the change of underground pore water pressure. Contents of the invention [0003] In view of this, the present invention proposes a method for detecting hydraulic pressur...
