Constant-pressure crack grouting control system and control method

The invention discloses a constant-pressure crack grouting control system which comprises a piston container, a grouting crack platform is connected to a grout outlet of the piston container, a plunger pump is connected to the end, away from the grouting crack platform, of the piston container, and a pressure sensor and a flow sensor are arranged on the grouting crack platform. The pressure sensor and the flow sensor are connected with the data acquisition instrument, the data acquisition instrument is connected with the central processing unit, the central processing unit is connected with the plunger pump, multiple cracks of different sizes can be grouted at the same time, and the flowing condition of grouting materials in the cracks can be observed. The invention further discloses a constant-pressure crack grouting control method adopting the control system, pressure and flow information can be monitored in real time, the opening degree of the plunger pump is controlled, and operation is easy. 本发明公开了恒压裂隙注浆
