Description

Pre-buried formula section of jurisdiction bight is sealed fills up
Technical Field
The utility model relates to a building technical field refers in particular to a pre-buried formula section of jurisdiction bight is sealed fills up.
Background
A large number of subways and tunnels are built at home and abroad, a mature structural design calculation theory and engineering practice system is gradually formed, but the understanding on the waterproof aspect of the tunnels and underground engineering is relatively laggard. The subway inevitably passes through a stratum with higher water content (for example, a stratum where iron is located is mostly a saturated water-containing soft clay layer), so that the subway is necessarily subjected to the harmful effect of underground water. Without reliable waterproof and leakage stopping measures, underground water can invade the tunnel to influence the internal structure and auxiliary pipelines of the tunnel, even harm the operation of the subway and reduce the service life of the tunnel. The positions of the water leakage of the shield tunnel are the seams of the segments, the small cracks of the segments, the grouting holes, the hand holes and the like. Wherein the joint of the pipe piece is taken as the waterproof key point.
The joint between the segments is waterproofed by arranging the pre-embedded segment sealing gasket on the segments in the prior art, the anchor feet which are arranged in the segments in a long way and are anchored on the existing pre-embedded segment sealing gasket are used for increasing the connection strength between the segment sealing gasket and the segments, but the anchor feet are arranged at the corner parts of the segments to cause new problems, the corner parts of the segments are usually formed by splicing and fixing two segments of segment sealing gaskets, the stress performance is limited, the segments are spliced and then are subjected to extrusion acting force between the segments, so that the stress concentration of the joint of the two segments of segment sealing gaskets is realized, the segment sealing gasket at the joint is easily deformed, and the anchor feet are driven to deform, and further the anchor feet anchored in the segments drive the segment concrete to break the segments around the anchor feet.
