Steep slope soil rock tunnel portal underground excavation bridge and tunnel and side slope parallel construction method
The invention discloses a steep slope soil rock tunnel portal underground excavation bridge and tunnel and side slope parallel construction method, and relates to the technical field of steep slope soil rock tunnel portal construction. The construction sequence includes that construction of a bridge abutment foundation pit excavation pouring retaining wall is conducted while tunnel open cut tunnelinverted arch construction is conducted, construction of a bridge abutment pile foundation and a bearing platform is conducted while open cut tunnel lining and tunnel portal construction is conducted, a bridge abutment is constructed, and finally, side slope protection construction is conducted while bridge and tunnel transition section construction is conducted. The defects that the constructionperiod is long and the construction cost is high due to the fact that existing tunnel open cut tunnel, tunnel portal and tunnel portal side slope protection and bridge abutment parallel constructioncannot be conducted are overcome, parallel construction of the process can be achieved, therefore, the construction period can be shortened, and the cost can be reduced.
本发明公开了一种陡坡土岩隧道口暗挖桥隧及边坡平行施工法，涉及陡坡土岩隧道口施工技术领域，施工顺序依次为：隧道明洞仰拱施工的同时进行桥台基坑开挖浇筑挡土墙施工，明洞衬砌及洞门施工同时进行桥台桩基及承台施工，桥台施工，最后，桥隧过渡段施工同时进行边坡防护施工。本发明克服了现有的隧道明洞、洞门、洞口边坡防护以及桥台无法平行施工导致施工工期长和施工成本高的缺陷，本发明能够实现上述过程的平行施工，从而有利于缩短施工工期和成本。
