Drilling, grouting and hole sealing construction system for karst subsidence area

The utility model discloses a drilling, grouting and hole sealing construction system for a karst subsidence area, relates to the technical field of drilling, grouting and hole sealing equipment, and aims to solve the problems that an existing drilling device is large in vibration, the drilling direction is prone to deviation, drilling fails, the heat dissipation effect of a shell is poor, and the service life of the shell is prolonged. According to the technical scheme, the drilling device comprises a transmission box and fixing blocks, the fixing blocks of the same structure are fixedly installed at the four corners of the outer wall of the transmission box, a chuck is rotatably installed on the outer wall of the bottom of the transmission box, and a drill bit is fixedly installed at the bottom of the chuck. And a double-shaft motor is fixedly mounted in the transmission box. The drilling device is novel in structure, solves the problems that an existing drilling device is large in vibration, the drilling d
