Multi-capsule soil deformation control device with controllable expansion sequence

The invention discloses an expansion sequence controllable multi-capsule soil deformation control device which comprises a deformation control assembly, a grouting pump, a grouting inner pipe, a grouting outer pipe, grouting capsules, a flow meter and a pressure gauge, the grouting inner pipe is communicated with the grouting pump, the grouting outer pipe is arranged on the outer side of the grouting inner pipe in a sleeving mode, the flow meter is arranged on the outer side of the grouting capsule, and the pressure gauge is arranged on the outer side of the grouting capsule. The grouting bag body is fixed to the outer side of the grouting outer pipe, the flow meter and the pressure gauge are both fixed to the grouting inner pipe, and a first grouting hole is formed in the position, located in the grouting bag body, of the grouting outer pipe. Through cooperation of the deformation control assembly and the grouting assembly, a constructor can freely control the sequence of bag body grouting when controlling d
