Construction method for reinforcing obstacle pile to be broken in underground tunnel construction
The invention discloses a construction method for reinforcing a to-be-broken obstacle pile in underground tunnel construction. The construction method comprises the following steps that firstly, construction preparation is conducted; secondly, micro pile construction is conducted through hole forming, reinforcement cage inserting, grouting and top beam construction; thirdly, a construction platform is erected; fourthly, an initial well is excavated and supported; 5, guide rail pouring and backrest supporting are conducted; sixthly, various construction devices are installed; seventhly, the existing obstacle pile to be broken and removed is reinforced through crossed pre-stressed anchor cable locking construction; 8, the obstacle piles are broken in a static crushing mode; and ninthly, jacking construction and monitoring are conducted. According to the method, the obstacle piles can be broken and effectively reinforced in the tunnel excavation process.
本发明公开了一种地下隧道施工加固拟破除障碍桩施工工法，该工法通过以下步骤实现：步骤一、进行施工准备；步骤二、通过成孔、插入钢筋笼、灌浆和冠梁施工进行微型桩施工；步骤三、施工平台搭设；步骤四、初始井开挖和支护；步骤五、导轨浇筑和靠背支设；步骤六、安装各类施工设备；步骤七、采用交叉预应力锚索锁定施工对既有拟破除障碍桩桩进行加固处理；步骤八、以静力破碎的方式破除障碍桩；步骤九、顶进施工及监测。本发明能够在隧道开挖过程中对障碍桩进行破除并进行有效加固。
