Problems solved by technology

[0002] With economic development and social progress, a large number of underground tunnel projects are planned in the Beijing area. For tunnels excavated by shield machines, single-track rail transportation is generally used, and the speed of muck transportation is not high. In shallow buried tunnels The method of using two-lane and two-track transportation has not yet appeared

Embodiment Construction

[0031] The method will be described in detail below in conjunction with the drawings and embodiments.

[0032] The double-line arrangement rule of the track adopts the herringbone cross arrangement in the double-arch tunnel, and the track line is converted from one side line to the other line.

[0033] The specific wiring steps of the double-line layout of the track are as follows:

[0034] The S1 double-arch tunnel is a double-line tunnel, and the middle of the double-line tunnel is divided by the middle partition into: the left line 1 of the rail transportation line and the right line 2 of the rail transportation line ( figure 1 ), enter the double-arch tunnel from the left and right holes respectively;

[0035] S2 curve segment 4( figure 1 ) use the steel frame 5 ( figure 1 ) to reinforce the hole, in the steel frame 5 ( figure 1 ) are installed with induction traffic lights at the front and rear ends, and the steel frame 5 ( figure 1 ) front and rear tracks ( figure ...

Abstract

The invention discloses a method for laying a double-line track on a soft foundation in a water-rich tunnel with double arches. The method for laying a double-line track on a soft foundation includes line planning, roadbed treatment, and steel sleeper design. In the double-arch tunnel, the double-line crossing of the track is arranged, and the tunnel is driven into the tunnel from the double-line of the shaft. When digging about 50m in, a hole is opened and reinforced on the partition wall. Sensor traffic lights are installed before and after the reinforced steel frame to remind passers-by to pass or wait. ; At the same time, the track here is closed with concrete, leaving only two driving tracks for electric vehicles to pass through; at this time, the line splits forward in a herringbone shape, and the herringbone branch in the next 50m opening will drive in a single track, but always keep left and right The tunnel has two lines for the operation of the power-driven transport system. Steel sleepers are profiled steel sleepers. The present invention uses double-line rail transportation to improve the transportation speed and increase the single-time transportation volume; the double-line rail transportation undertakes the transportation of construction materials at the same time, which saves equipment investment and is economical and applicable.

Description

technical field [0001] The invention relates to a method for transporting muck out and material in by using a double-track track in a double-arch water-rich tunnel, so as to improve the efficiency of muck transportation, and belongs to the technical field of urban rail construction. Background technique [0002] With economic development and social progress, a large number of underground tunnel projects are planned in the Beijing area. For tunnels excavated by shield machines, single-track rail transportation is generally used, and the speed of muck transportation is not high. In shallow buried tunnels The method of using two-lane and two-track transportation has not yet appeared. In view of this, the present invention proposes a method for laying double-track tracks in double-arch water-rich tunnels. Contents of the invention [0003] The purpose of the present invention is to propose a method of using double-track material transportation on the soft roadbed in the doubl...
