Embodiment Construction

[0034] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings, but they do not constitute a limitation to the present invention, and are only examples. At the same time, the advantages of the present invention are clearer and easier to understand through the description.

[0035] Referring to the accompanying drawings, it can be seen that the sewage tunnel segment structure is characterized in that it includes a shield segment 1, a tapered connector 2 and a plug-in connector 3, and the upper and lower ends of the side of the shield segment 1 are tapered. Part 2, the longitudinal seams of multiple shield segments 1 are connected by tapered connectors 2, and the annular seams of multiple shield segments 1 are connected by plug-in connectors 3;

[0036] Both the longitudinal seam and the annular seam of the shield segment 1 are provided with a water-stop structure 4;

[0037] A PVC sheet 11 is pre-embedded in t...

Abstract

The invention discloses a sewage tunnel segment structure and relates to the field of sewage tunnel engineering. The segment structure comprises a shield segment body, conical connecting pieces and an insertion type connecting piece, wherein the conical connecting pieces are arranged at an upper end and a lower end of the side face of the shield segment body, longitudinal seams of the shield segment body are connected through the conical connecting pieces, and circular seams of the shield segment body are connected through the insertion type connecting piece; and a PVC sheet is pre-embedded in the inner wall of the shield segment. The segment structure is suitable for conveying sewage or other corrosive liquid in a large-section pipeline in a corrosive environment, the PVC sheets are pre-buried in the shield segment, and the conical connecting pieces and the insertion type connecting pieces are adopted between the segments, so hand hole plugging of the segments is eradicated, the welding number of the PVC sheets is reduced, welding seam working efficiency is improved, engineering investment is reduced, and the segment structure is suitable for large-section sewage pipeline discharge projects. The invention further relates to a construction method of the sewage tunnel segment structure.

Description

technical field [0001] The invention relates to the field of sewage tunnel engineering, and more specifically relates to a sewage tunnel segment structure. The invention also relates to a construction method of the sewage tunnel segment structure. Background technique [0002] Sewage contains a variety of media, such as acid, alkali, salt, and agricultural production system substances, which will cause serious corrosion to reinforced concrete structures under long-term action; in addition, in the structural section of the sewage tunnel, the oxygen concentration of different structural parts above and below the water level The difference is large, and the oxygen concentration in the water is often changing. The difference in oxygen concentration in the tunnel will cause concentration cell corrosion; the composition and microporous structure of concrete face leaching corrosion, exchange corrosion and crystallization corrosion, causing concrete corrosion. Cracking and corrosio...
