1 ,pressure pauge: the main part of the lateral pressure device: three skeleton cylindrical cavity, the outer elastic film. There are three cavities: upper, middle, and lower. The middle cavity is the test cavity; the upper and lower cavities are connected to each other but isolated from the middle cavity and are protected. There is a water pipe in the center, which is used to drain groundwater, so that the pressure bypass device can be placed at the test depth smoothly.
2 , the water tank: mainly used for injection before the test, the test pressure is not. In order to avoid cracking, a safety valve is installed.
3 , the deformation measuring system:
( 1 ) The function of the measuring tube is to display the volume change of the pressure side device. Two scales , S and V , are set beside the measuring tube .
S ruler-engraved with a standard length, the smallest scale is 1 mm, for reading the value of the liquid level drop ( cm ) of the measuring tube caused by the expansion of the pressure bypass device .
V --The volume increase ( cm 3 ) after expansion of the pressure regulator is determined by the position of the liquid level .
( 2 ) The pressure guiding tube is made of imported nylon -11 fiber (high-pressure resistant material) , which is a pipeline for transmitting pressure.
