Efficient and environment-friendly mountain excavation tunnel-entering construction method
The invention relates to an efficient and environment-friendly mountain excavation tunnel-entering construction method. The efficient and environment-friendly mountain excavation tunnel-entering construction method comprises the following steps of slope top catchwater construction, passive protection net construction, vegetation cleaning, active protection net construction, pregrouting for rock consolidation, concrete guide wall construction, large pipe shed construction, and tunnel entrance through a core soil reserving method. Earth-rock open cutting engineering scale and engineering quantity on a tunnel opening portion can be greatly reduced, manpower and material resource input of earth-rock open cutting can be reduced or avoided, meanwhile, tunnel opening area excavating can be reduced to the maximum degree, damage to mountain vegetation and ecological environment can be reduced to the maximum degree, ecological balance and mountain stress balance of the tunnel opening portion canbe kept, the natural disaster induced by the construction can be avoided or reduced, meanwhile, procedure conversion of tunnel opening open cutting and tunnel excavating can be quickened, the time can be effectively shortened, and tunnel excavating construction capacity can be formed as soon as possible.
本发明涉及一种高效环保山体开挖进洞施工方法，包括如下步骤：坡顶截水沟施工、被动防护网施工、植被清理、主动防护网施工、预灌浆固结岩体、混凝土导墙施工、大管棚施工以及预留核心土法进洞。本发明能够大大降低洞口部位的土石方明挖工程规模及工程量；降低或避免了土石方明挖的人力物力方面投入；同时最大限度减少洞口区域开挖，和对山体植被及生态环境的破坏，保持洞口部位生态平衡和山体受力平衡，避免或降低因施工诱发的自然灾害。同时能加快洞口明挖及洞挖的工序转换，有效缩短降低时间，尽快形成洞挖施工能力。
