Half-open and half-hidden tunnel entering construction method for unsymmetrical pressure tunnel
The invention discloses a half-open and half-hidden tunnel entering construction method for an unsymmetrical pressure tunnel. The method comprises the following steps that firstly, an edge and front slope is excavated and protected; secondly, a bias retaining wall and a semi-open side support are constructed; thirdly, the bias retaining wall and the guide wall are constructed; 4, supporting construction on the side close to the mountain; 5, tunnel portal excavation construction is carried out; and step 6, backfilling. According to the method, the excavation degree of the semi-dark side of the semi-open and semi-dark bias tunnel is reduced, the side upward slope is excavated, and various supporting measures are taken for the side upward slope, so that damage to the mountain environment around the tunnel portal is reduced, the natural environment of the tunnel portal is protected, and the stability of the surrounding mountain is ensured; meanwhile, an unsymmetrical pressure retaining wall is poured on the half-open side of the half-open and half-dark unsymmetrical pressure tunnel to support and reinforce the unsymmetrical pressure part of the half-open and half-dark unsymmetrical pressure tunnel, and a stable reinforcing effect is provided for excavation of a tunnel portal; the construction time of the semi-open and semi-dark bias tunnel portal can be effectively shortened, and the construction cost is saved.
本发明公开了偏压隧道半明半暗进洞施工方法，包括以下步骤：步骤一、边仰坡开挖及防护；步骤二、偏压挡墙及半明侧支护施工；步骤三、偏压挡墙及导向墙施工；步骤四、靠山侧支护施工；步骤五、隧道洞口开挖施工；步骤六、回填。本发明通过减少对半明半暗偏压隧道的半暗一侧的开挖程度，挖开边仰坡并对边仰坡设置多种支护措施，从而降低了对隧道洞口周边山体环境的破坏，保护了隧道洞口的自然环境，确保了周围山体的稳定性；同时在半明半暗偏压隧道的半明一侧浇筑偏压挡墙对其偏压部分进行支撑加固，为隧道洞口的开挖提供稳定的加固效果；本发明能够有效缩短半明半暗偏压隧道洞口的施工时间、节约施工成本。
