Abstract

The present invention relates to the field of foundation penetration test, in particular to a building foundation site penetration test device and a test method thereof, comprising a water tank, a water pressure mechanism, a first water pipe, a first hydraulic plug, a second water pipe, and a second hydraulic pressure plug. The water pressure mechanism includes a pressure regulating water pump, a flow meter and a pressure gauge. The input port of the pressure regulating water pump is connected with the water tank. The output port of the pressure regulating water pump is equipped with a flow meter. The bottom end of the second water pipe is installed with The first electromagnetic three-way valve, the bottom end of the second hydraulic plug is equipped with a solenoid valve, the first water pipe, the first hydraulic plug, the second water pipe, the first electromagnetic three-way valve, the second hydraulic plug, The solenoid valves are connected sequentially from top to bottom; the test device and its test method solve the problem that the residual debris in the hole affects the test results, and at the same time solve the problem that the air in the test area cannot be discharged, and also solve the problem of the air above the test area. The water pressure generated by the water column reduces the working life of the hydraulic plug.

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...
