The invention belongs to the technical field of simulation test equipment for drilling grouting, and relates to a simulation test device for drilling grouting. According to the simulation test device for drilling grouting, fixing rod holes are formed in the peripheries of a sealing top cover and a sealing base, the upper ends of tank body fixing rods are fixed on the sealing top cover, and the lower ends of tank body fixing rods are fixed on the sealing base; a grouting sealing hole is formed in the centre of the sealing top cover, a grouting pipeline penetrates through the grouting sealing hole and is connected with a grouting control system of a test control system, and a stress-strain transmission line penetrates out through a transmission line sealing hole and is connected with the stress data acquisition plate of the test control system; a grouting sealing tank body is installed and produced between the sealing top cover and the sealing base, a hole wall stress-strain sensor is produced on the inner sidewall of the grouting sealing tank body, a tank wall stress-strain sensor is produced on the outer sidewall of the grouting sealing tank body, and the hole wall stress-strain sensor and the tank wall stress-strain sensor are connected with the stress data acquisition plate of the test control system. The simulation test device for drilling grouting is simple in structure, convenient to operate, simple and convenient in method during a test, and accurate in the acquired and monitored data.
