Abstract

The invention relates to the field of foundation penetration tests, and particularly relates to a building foundation field penetration test device and a test method thereof. The device comprises a water tank, a water pressing mechanism, a first water pipe, a first hydraulic plug, a second water pipe, a second hydraulic plug and a controller, wherein the water pressing mechanism comprises a pressure regulating water pump, a flow meter and a pressure gauge, the input port of the pressure regulating water pump is communicated with the water tank, the output port of the pressure regulating waterpump is installed with the flow meter, a first electromagnetic three-way valve is installed at the bottom end of the second water pipe, an electromagnetic valve is installed at the bottom end of the second hydraulic plug, and the first water pipe, the first hydraulic plug, the second water pipe, the first electromagnetic three-way valve, the second hydraulic plug and the electromagnetic valve aresequentially connected from top to bottom. By adopting the test device and the test method thereof, the problem that the residual debris in the hole affects test results can be solved, and meanwhile,the problem that air in a test area cannot be discharged can be solved, and the problem that the water pressure produced by a water column above the test area reduces the operating life of the hydraulic plugs can also be solved.

Description

technical field [0001] The invention relates to the field of foundation penetration tests, in particular to a field penetration test device for building foundations and a test method thereof. Background technique [0002] Building foundations are divided into natural foundations and artificial foundations. The foundation that can directly bear the load of the building without treatment is called the natural foundation, and conversely, the foundation that needs to be treated by the foundation treatment technology is called the artificial foundation. [0003] In many hydraulic structures, earth dams and foundation pit projects, the seepage force is one of the important factors affecting the safety of the project. [0004] In actual projects, there have been many cases of seepage damage (soil flow or piping), which seriously interrupted the construction of the project and even endangered the safety of adjacent buildings and facilities. [0005] Therefore, during engineering d...
