[0019] Embodiment 1: the construction process of the damping type block lining structure is as follows:
[0020] After the underground cavern is excavated and the primary support structure 4 is constructed, the buffer layer 3 is installed closely to the primary support structure 4, and then the lining block 2 and the damper 5 connected with the lining block 2 are installed in sequence.
[0021] The circumferential joint surface of the two adjacent lining blocks 2 is respectively grooved to install the damper 5, and the two ends of the damper 5 are fixed on the two adjacent lining blocks through the fixing blocks 6.
