| description | The invention relates to the technical field of battery management, in particular to a small-clear-distance tunnel weak surrounding rock deformation control device which comprises two bases, two hydraulic jacks fixedly installed on the upper surfaces of the two bases respectively and a supporting plate. A plurality of inserting plates are fixedly installed on the lower surface of the supporting plate, and a plurality of penetrating openings are formed in the upper surface of the fixing block. A plurality of through holes are formed in the side wall of the fixing block, inserting rods are slidably inserted in the through holes, locking blocks are fixedly installed at one ends of the inserting rods, abutting parts are arranged on the side wall of the installation plate, and locking holes for the locking blocks to be inserted in are formed in the surface of the inserting plate. Through cooperation of the locking block, the inserting plate, the locking opening and the abutting part, mounting and dismounting betwe |
