Large-section mining method tunnel construction method
The invention relates to the technical field of tunnel construction, in particular to a large-section mining method tunnel construction method. The invention provides a double-side-wall pilot tunnel and hole-pile composite construction method by combining the advantages of a double-side-wall pilot tunnel and a hole-pile method when a large broken mountain mining method tunnel underneath passes through a building. The upper half section is divided into three pilot tunnels to be excavated according to the double-side-wall pilot tunnel principle, a primary support and an arch cover are constructed, after the arch cover is formed, the arch cover and the structural pile form are used for forming a whole, effective support is formed for the lower half section, then the lower half section is excavated, and a lining of the lower half section is constructed.
本发明涉及隧道施工技术领域，特指一种大断面矿山法隧道施工方法。本发明在大断山矿山法隧道下穿建构筑物时，结合双侧壁导坑以及洞桩法的优点，提出了双侧壁导坑与洞桩复合施工工法。上半断面采用双侧壁导坑的原理分成三个导洞进行开挖、施作初支及拱盖，拱盖形成之后，利用拱盖及结构桩型形成整体，对下半断面形成有效支撑，随后开挖下半断面，施工下半断面衬砌。
