Unfavorable geology small-section tunnel excavation construction method
The invention discloses a construction method for excavating a small-section tunnel in unfavorable geology. The construction method comprises the following steps: performing construction measurement; carrying out construction lofting; constructing intercepting and draining ditches; carrying out earth excavation construction; supporting the side slope; forepoling; advanced geological forecasting; excavating a tunnel body; and performing primary support and lining construction. According to the method, the whole process from early-stage investigation to later-stage supporting is helpful for coping with different geological conditions and construction challenges in different stages, and through systematic management and prediction, the construction risk can be reduced, and the success rate of engineering can be improved.
本发明公开了一种不良地质小断面隧洞开挖施工工法，包括：施工测量；施工放样；截、排水沟施工；土方开挖施工；边坡支护；超前支护；超前地质预报；隧洞洞身开挖；初期支护以及衬砌施工。本发明从前期勘察到后期支护的全过程，有助于在不同阶段应对不同的地质条件和施工挑战，通过系统性的管理和预测，可以降低施工风险，提高工程的成功率。
