Further: the connecting structure is characterized in that bolt holes of the four parts, namely the outer covering plate, the inner covering plate, the annular lap joint part of the corrugated pipe sheet and the rubber plate, are correspondingly penetrated and connected through bolts, sliding rings are respectively sleeved on bolts at the long round holes of the outer covering plate and the inner covering plate during connection, the sliding rings can be driven by the bolts to slide in the long round holes of the outer covering plate and the inner covering plate, and large gaskets are sleeved at the outer covering plate and the inner covering plate on the sliding rings.
The utility model has the advantages that:
1. the annular pressure resistance of the steel butt joint corrugated pipe can be enhanced, the sealing performance is good, the deformation caused by the fact that the foundation is stressed unevenly and the backfill density cannot reach the standard can be solved, and meanwhile the construction cost is reduced.
2. Outer shroud plate and interior shroud plate on wear to establish the rectangular round hole that the hole of bolt was seted up for the axial, cover the board outside during the connection, the slip ring is overlapped respectively on the bolt of the rectangular hole department of interior shroud plate, the bolt area slip ring can slide in the rectangular round hole of outer shroud plate and interior shroud plate, the bellows slab can follow the slip ring and remove in rectangular round hole together, the junction that makes two bellows slabs has certain flexible volume, with the flexible deformation of adaptation junction, avoid causing the shaft of a pipe to destroy because of the inhomogeneous settlement of basis.
3. The rubber plate is installed with bellows hoop overlap joint part to interior shroud plate, has the ripple section of inside recess on the rubber plate, can make the hoop installation inseparable more of laminating, has guaranteed the leakproofness.
4. The axial middle part of outer shroud plate has the ripple section of hoop evagination, and the axial middle part of interior shroud plate also has the ripple section of hoop indent, and deformation that seam department produced because the basis atress is inhomogeneous, backfill highly big can effectual solution of this kind of structure has increased annular compressive capacity.
5. The utility model can limit the culvert to generate regular and fixed cracks, and can treat the expansion device in advance; if the differential settlement exists, the expansion joint is limited, which is beneficial to the safety, stability and seepage prevention of the culvert, and prevents the water flow in the pipe from permeating into the culvert foundation or the roadbed to cause the soil to be soaked and softened.
