For achieving the above object, the technical solution adopted in the utility model is immersed tube tunnel steel end envelope wall and concrete fixed structure, and this structure comprises pipeline section side wall concrete 1, angle steel 2, steel end envelope wall 3, rubber spacer 4, dowel screw 5, fixing top board 6; Described pipeline section side wall concrete 1 and pipeline section steel end seal to form to join between wall 3 and stitch, and the inner side being positioned at the pipeline section side wall concrete 1 of handing-over seam is embedded with angle steel 2, dowel screw 5, wherein vertical the and angle steel 2 of dowel screw 5, and each dowel screw 5 is parallel to each other and is arranged symmetrically with; Be provided with rubber spacer 4 between steel end envelope wall 3 and angle steel 2, dowel screw 5 one is fixed in pipeline section side wall concrete 1, and the other end seals wall 3 through rubber spacer 4, steel end and is fixed on steel end envelope wall 3 side by nut.
Described pipeline section side wall concrete 1 and pipeline section steel end seal the handing-over formed between wall 3 and stitch top pre-installation and have fixing top board 6, fixing top board 6 one end is fixed in pipeline section side wall concrete 1, the other end is cantilever construction, and the welded top of steel end envelope wall 3 is bottom fixing top board 6.
The external surface of described pipeline section side wall concrete 1 scribbles epoxy resin.
Described fixing top board 6 bracketed part length is 2.5-3.5 times of steel end envelope wall 3 thickness.
The spacing that described angle steel 2 and steel end seals wall 3 is 0.9-0.95 times of rubber spacer 4 thickness.
Compared with prior art, the beneficial effects of the utility model are as follows.
1, this structure adopts partly welding, half bolt to be connected and fixed mode, and immersed tube steel end envelope wall and pipeline section concrete structure are joined stitch waterproof fixed structure and carry out optimal design again, can effectively ensure immersed tube pipeline section waterproof effect and quality, and easy construction quality easy to control.
2, the utility model is to the pre-buried angle steel in immersed tube pipeline section concrete side, concrete external surface is provided with epoxy resin scratch coat, ensure that immersed tube tunnel stitches waterproof effect quality at pipeline section steel end envelope wall in joining with pipeline section concrete structure, avoiding occurring handing over gaping of joints to occur infiltration.
