Construction method of fabricated underground passage crossing road
The invention discloses a construction method of a fabricated underground passage crossing a road. Comprising the steps of guard pile construction, joist construction, isolation wall construction on the two sides of a channel, soil body reinforcement on the two sides of the channel, channel top reinforcement, soil body reinforcement in a channel excavation area, channel bottom grouting reinforcement, channel excavation and primary support, channel structure installation, grouting sealing and removal of the joist and the guard piles exposed out of the earth surface. According to the method, construction measures such as pre-underpinning, comprehensive pre-reinforcement, segmented and partitioned cross excavation, a comprehensive supporting mode and an assembly type channel structure are adopted, and the influence of undercrossing channel construction on existing road traffic can be avoided. Meanwhile, road settlement can be reduced through underground excavation construction, construction safety is guaranteed, the technology is simple, safety and reliability are achieved, the construction speed is high, and applicability is high.
本申请公开了一种穿越道路的装配式地下通道施工方法，包括防护桩施工、托梁施工、通道两侧隔离墙施工、通道两侧土体加固、通道顶部加固、通道开挖区域土体加固、通道底部注浆加固、通道开挖与初期支护、安装通道结构、注浆封闭以及拆除托梁和出露地表的防护桩。该方法采用预先托换、综合预加固、分段分区交叉开挖、综合支护方式、装配式通道结构等施工措施，可以避免下穿通道施工对既有道路交通影响。同时采用暗挖施工可以减少道路沉降，保证施工安全，且技术简单、安全可靠、施工速度快、适用性强。
