Existing line crossing tunnel portal roadbed and a construction method
The invention relates to an existing line crossing tunnel portal roadbed and a construction method. The method comprises the following steps: step 1, driving an earth surface observation pile; step 2, constructing an anti-rolling stone soil ditch; step 3, constructing a protective bent frame system; step 4, performing catchwater construction; step 5, performing roadbed construction; and step 6, performing tunnel structure detection. The anti-rolling stone earth ditch and the protective bent frame system are combined to protect the portal of the operation tunnel in the roadbed excavation process, the safety of the roadbed construction process is improved, and the influence on the operation tunnel is reduced; temporary drainage ditch construction is conducted through the temporary drainage ditch rapid construction support, and the temporary drainage ditch construction speed is increased; and the tunnel detection walking support is used for detecting the tunnel structure in the operation tunnel, the tunnel detection efficiency is improved, and meanwhile the influence on operation of the operation tunnel is reduced.
本发明涉及一种横穿既有线隧道洞口路基及施工方法，所述方法包括步骤一、地表观测桩打设；步骤二、防滚石土沟施工；步骤三、防护排架体系施工；步骤四、截水沟施工；步骤五、路基施工；步骤六、隧道结构检测。本申请采用防滚石土沟和防护排架体系组合对路基开挖过程中对运营隧道洞口的防护，提高路基施工过程的安全性，减少对运营隧道的影响；采用临时排水沟快速施工支架进行临时排水沟施工，提高临时排水沟施工速度；采用隧道检测行走支架对运营隧道内隧道结构进行检测，提高隧道检测效率，同时减少对运营隧道的运营影响。
