Problems solved by technology
[0002] The single-channel logistics construction method is usually used in the tunnel, but for some special geological emergency rescue and renovation projects, thousands of people are operating in the tunnel at the same time during the peak period, the tunnel construction period is tight, there are many working surfaces in the tunnel, and the construction process is closely connected , and it is a single-track tunnel, with many transport vehicles and limited transport channels, which is prone to congestion and increases the working time of each process. The current single-channel logistics construction method cannot meet the requirements of the construction schedule

Embodiment Construction
[0029] In the following, the present invention will be further explained through the embodiments and the accompanying drawings:
[0030] A kind of invert double channel logistics construction method, such as figure 1 As shown, a parallel pilot hole B parallel to the main hole A is provided in the tunnel, and the front and back ends of the parallel pilot hole B are respectively communicated with the main hole A through a cross channel C. This construction method borrows the existing parallel pilot tunnel as the logistics channel, forming a dual channel with the main tunnel of the tunnel.
[0031] Specific steps are as follows:
[0032] (1) Use the inverted arch reinforcement cage to process the frame in the parallel guide tunnel to bind the inverted arch reinforcement cage;
[0033] The tying of the steel cage needs to use the steel cage to process the frame. Because the inverted arch reinforcement cage is an arc-shaped frame formed by tying steel bars, the last misalignment and later...

The invention discloses an inverted arch double-channel logistics construction method. The method comprises the following steps: combining a parallel pilot tunnel and a main tunnel to form double logistics channels, performing inverted arch reinforcement cage binding in the parallel pilot tunnel, realizing inverted arch reinforcement recess fixed transport by utilizing a gun carriage and a reinforcement cage locking rack, hoisting an inverted arch reinforcement cage into an inverted arch pit to be mounted by utilizing an inverted arch reinforcement cage hoisting truss in the main tunnel, hoisting two trestle bridges onto the inverted arch reinforcement cage to form double trestle bridges by utilizing the inverted arch reinforcement cage hoisting truss, mounting a reinforcement cage translation tool by utilizing the double trestle bridges, and performing horizontal fine adjustment on the inverted arch reinforcement cage by utilizing the reinforcement cage translation tool. The traffic and construction pressure in the tunnel is alleviated, and the construction efficiency is improved.
Description
Technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a construction method of dual-channel logistics in a tunnel. Background technique [0002] Single-channel logistics construction methods are usually used in tunnels, but for some special geological emergency rescue and remediation projects, there are thousands of people working in the tunnel at the same time during the peak period. The tunnel construction period is tight, there are many working surfaces in the tunnel, and the construction process is compact. , And it is a single-lane tunnel with many transportation vehicles and limited transportation channels. Congestion is prone to occur, which increases the operation time of each process. The current single-channel logistics construction method cannot meet the requirements of the schedule. Summary of the invention [0003] In view of the above technical problems, the present invention aims to provide an inverted double-ch...
