Abstract

The invention relates to an anti-seepage subway tunnel segment which is installed in a tunnel, the segment comprises segment bodies, inserting holes and inserting grooves corresponding to the inserting holes are formed in the lower surfaces of the segment bodies, the two segment bodies are fixed through bolts, and installation grooves and matching grooves are formed in the segment bodies; a plurality of abutting springs are fixedly connected to the groove bottom wall of the mounting groove, a sealing block is jointly and fixedly connected to the abutting springs, the sealing block is slidably inserted into the mounting groove, a mounting hole penetrating through the sealing block is formed in the upper surface of the sealing block, and two sleeves are slidably connected into the mounting hole; a plurality of sealing springs are fixedly connected to the inner bottom wall of the sleeve, a sealing plate is jointly and fixedly connected to the sealing springs, the sealing plate is inserted into the sleeve in a sliding mode, and when the sealing springs are in a natural state, the sealing plate protrudes out of the sealing block. The method has the effect of reducing the adverse effect on the service life of the equipment in the tunnel.

Description

technical field [0001] The present application relates to the field of subway engineering, in particular to a seepage-proof subway tunnel segment. Background technique [0002] Segment is the main assembly component of shield construction and the innermost barrier of the tunnel, which bears the role of resisting soil pressure, groundwater pressure and some special loads. The segment is the permanent lining structure of the shield tunnel. The quality of the segment is directly related to the overall quality and safety of the tunnel, and the quality of the segment affects the waterproof performance and durability of the tunnel. [0003] Several waterproof strips are inlaid on the existing segment, and two waterproof strips are generally arranged, and the two waterproof strips are arranged along the height direction of the segment. When installing the segment, the operator installs the segment on the inner wall of the tunnel one by one, so that the multiple segments form a cir...
