Open cut tunnel construction method without disturbing side slope
The invention relates to the technical field of road engineering, and particularly relates to an open cut tunnel construction method without disturbing a side slope. According to the technical scheme, the method comprises the following steps that slope brushing is conducted on the slope surface of the side slope at the open cut tunnel construction position; outer side reinforced concrete construction is conducted at the open cut tunnel construction position, so that outer side secondary lining concrete is poured to the inner side slope, and a connector is reserved; after the outer side secondary lining concrete of an open cut tunnel reaches the design strength, a support is arranged below the outer side secondary lining concrete; pipe curtain construction is conducted on the outer side secondary lining concrete, so that one end of a pipe curtain is inserted into a mountain on the inner side of an excavation influence line, and the other end of the pipe curtain is erected at the upper end of the inner side of the outer side secondary lining concrete; and tunnel excavation construction is conducted below the pipe curtain according to the design width of the open cut tunnel, and inner side secondary lining pouring is conducted. According to the open cut tunnel construction method, the open cut tunnel can be constructed under the condition that the side slope is not disturbed, and the open cut tunnel construction method has important significance in mountainous area road construction and environment protection.
本发明涉及道路工程技术领域，具体涉及一种不扰动边坡的明洞修建方法；采用的技术方案是：包括以下步骤，对明洞修建位置的边坡坡面进行刷坡；在明洞修建位置进行外侧钢筋砼施工，以将外侧二衬混凝土浇筑至内侧边坡并预留接驳器；在明洞外侧二衬混凝土达到设计强度后，在外侧二衬混泥土下方布设支架；在外侧二衬混凝土上进行管幕施工，以将管幕一端插入开挖影响线内侧的山体内，管幕另一端搭设在外侧二衬混凝土内侧上端；在管幕下方按照明洞设计宽度进行隧道开挖施工，并进行内侧二衬浇筑。本发明能够在不扰动边坡的情况下修建明洞，对山区道路建设和环境的保护具有重要的意义。
