盾构切削玻璃纤维筋直接进出洞施工技术

Construction technology of directly into and out of tunnel portal of cut glass fiber-reinforced polymer in shielding

佛山市南海区新交通1标土建工程采用泥水盾构切削玻璃纤维筋直接进出洞,避免了人工开凿围护结构,降低了施工风险,在全封闭式配有硬岩切削刀具的盾构始发、接收中应用前景广阔。文章针对泥水盾构在始发、接收中直接切削玻璃纤维筋进出洞施工技术进行阐述分析。

The Lot 1 civil engineering of the new transit projects in the Nanhai district,Foshan,uses the slurry shield to cut the glass fiber-reinforced polymer directly into and out of the tunnel portal.It avoids the manual labor tunneling envelop enclosure structure and reduces the construction risks.It has a prospective application in launching and receiving of shield with hard rock cutters for total tunnel enclosed shielding.This paper expounds and analyzes the construction technology of direct cutting of glass fi ber-reinforced polymer in the launching and receiving of slurry shield.
