Pipe jacking working well supporting device used for municipal pipeline engineering and construction method
The invention provides a pipe jacking working well supporting device used for municipal pipeline engineering. The pipe jacking working well supporting device used for municipal pipeline engineering isused for foundation pit protection in the pipe jacking working well foundation pit excavation process; the pipe jacking working well supporting device used for municipal pipeline engineering comprises a steel sheet pile structure and a reinforced concrete enclosure wall which are arranged in sequence from top to bottom in the depth direction of a foundation pit; the steel sheet pile structure comprises steel sheet pile bodies and steel enclosure purlins, wherein the steel sheet pile bodies and the steel enclosure purlins are arranged around the foundation pit; three steel enclosure purlins are arranged along the internal surface of each steel sheet pile body in sequence from top to bottom; angle braces are arranged at four corners of each steel sheet pile body; a circular hole is formed in the reinforced concrete enclosure wall in the pipe jacking pipeline advancing direction; and the diameter of the circular hole is larger than the external diameter of a jacking pipe. The invention further discloses a construction method of the pipe jacking working well supporting device used for municipal pipeline engineering; and effects of convenient and fast construction, repeated use, economization and environmental protection are realized.
本发明提供了一种用于市政管道工程顶管工作井支护装置，该支护装置用于顶管工作井基坑开挖过程中进行基坑防护，所述支护装置包括沿着基坑深度方向由上至下依次设置的钢板桩结构和钢筋混凝土围护墙，所述钢板桩结构包括沿着基坑四周设置的钢板桩本体和钢围檩，所述钢围檩沿着钢板桩本体内表面由上至下依次设置有三道，每道钢板桩本体的四角均设置有角撑，所述钢筋混凝土围护墙上沿着顶管管道行进方向上开设有圆形洞口，所述圆形洞口的直径大于顶管外径。本发明还公开了一种用于市政管道工程顶管工作井支护装置的施工方法，实现了施工便捷、重复使用、节约环保的效果。
