Embodiment Construction
[0035] Below in conjunction with accompanying drawing and embodiment the present invention is described further as follows:
[0036] Such as figure 1 As shown, the tunnel structure, including the inverted arch and the inverted arch backfill layer;
[0037] The inverted arch is spliced by a group of inverted arch units 1 along the longitudinal direction of the tunnel, and each inverted arch unit 1 is spliced by a group of inverted arch prefabricated blocks 11 along the tunnel ring direction; the combination of two adjacent inverted arch units 1 The seams between the surfaces form the invert arch circumferential seam 13, and the seams between the joint surfaces of two adjacent inverted arch prefabricated blocks 11 in each invert arch unit 1 form the invert arch longitudinal seam 12;
[0038] The inverted arch backfill layer along the longitudinal direction of the tunnel is formed by splicing a group of backfill units 2, and each backfill unit 2 along the tunnel ring directi...
