Problems solved by technology
[0002] At present, tunnels in subway intervals are generally constructed using the shield method. There are fewer tunnels in subway intervals constructed using the mining method compared with the shield tunneling method, and because the interval tunnels are generally shorter, when the mining method is used for construction, fewer auxiliary tunnels are set up. Other similar projects When setting the inclined shaft, the construction at the intersection of the inclined shaft and the main tunnel is extremely complicated

The invention provides a treatment method of single-line mining method subway tunnel inclined shaft top-hole displacement. The treatment method comprises the steps that the position close to a top hole and needed to be passed through is constructed according to a general inclined shaft cross section, wherein an inclined shaft comprises an inclined shaft wall, the inclined shaft wall is formed by adopting a preliminary bracing and secondary lining combined process; a new cross section is established in the inclined shaft and rightly faces a top-hole section, the inclined shaft is closed by adopting an end wall when construction is performed on the edge of the top hole, preliminary bracing is conducted on the top hole through stepped method construction, and top-hole secondary lining is conducted on a lining trolley during gradual advancing; the new cross section can be constructed before or after top-hole construction and while top-hole construction. Therefore, the technical problems of construction process simplification and construction period shortening are solved, cost reduction is achieved, and good effect of project progress acceleration is achieved.
Description
technical field [0001] The invention relates to the technical field of tunnel construction, in particular to provide a treatment method for the inclined shaft of a subway tunnel with a single-track mining method. Background technique [0002] At present, tunnels in subway intervals are generally constructed using the shield method. There are fewer tunnels in subway intervals constructed using the mining method compared with the shield tunneling method, and because the interval tunnels are generally shorter, when the mining method is used for construction, fewer auxiliary tunnels are set up. Other similar projects When setting the inclined shaft, the construction at the intersection of the inclined shaft and the main tunnel is extremely complicated. Through earnest research and experiments, the inventor has designed a design that can simplify the construction process, speed up the construction period, and can conveniently solve the technical problems of construction at the in...
