Sewage tunnel segment structure and construction method thereof
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.
本发明公开了一种污水隧道管片结构，涉及污水隧道工程领域。它包括盾构管片、锥型连接件和插入式连接件，盾构管片侧面的上下端均有锥型连接件，盾构管片的纵缝通过锥型连接件连接，盾构管片的环缝通过插入式连接件连接；盾构管片内壁预埋PVC片材。本发明适用于在腐蚀环境下大断面管道污水或其它腐蚀性液体的输送，通过在盾构管片内部预埋PVC片材，管片之间采用锥型连接件和插入式连接件，从而杜绝管片手孔封堵、减少PVC片材焊接数量，提高焊缝工作效率、减少工程投资，适用于大断面污水管道排放工程。本发明还涉及这种污水隧道管片结构的施工方法。
