Embodiment
[0021] Figure 1-3 It is shown that the specific embodiment of the present invention is a drainage type segment for tunnel lining, including a reinforced concrete segment 1, a grouting hole or a hoisting hole 1a in the segment 1, a stressed steel bar 1b, and an outer layer Concrete cover 1c. In the concrete protection layer 1c facing one or two grouting holes 1a of the segment 1, the waterproof glue block 2 that can expand in water is pre-embedded; The grouting hole or hoisting hole 1a is inserted, passes through the water-stopping rubber block 2, drills out the concrete protective layer 1c, and has a drainage hole 3a on the rod wall at the outer end of the self-advancing hollow anchor rod 3, and plugs it in its inner cavity. Filter column 4 for filter sand.
[0022] The length of the self-advancing hollow anchor rod 3 protruding from the concrete protection layer 1c in this example is 2-3m; the thickness of the glue block 2 is 2-3cm.
