Pressure grouting structure and pressure grouting method
The invention relates to the field of civil engineering and discloses a pressure grouting structure. The pressure grouting structure is characterized by comprising a container, a grouting pipe and an exhaust pipe, wherein the container is provided with a hole; the hole is provided with a sealing plate; the sealing plate is provided with a grouting through hole and an exhaust through hole; one end of the grouting pipe is connected with the grouting through hole and the other end of the grouting pipe is used for being connected with a grouting machinery; one end of the exhaust pipe is connected with the exhaust through hole and the other end of the exhaust pipe is provided with a reading ball valve; the exhaust pipe is provided with a chip hold down ball valve; a pressure gauge is arranged between the chip hold down ball valve and the reading ball valve. The invention also provides a pressure grouting method. According to the invention, by using the pressure gauge, a grouting pressure in the container can be accurately measured, the pressure in the container is accurately controlled, the condition that the container is damaged due to the excessively high pressure or the excessively low pressure does not accord wit the design requirement is avoided.
