During subway construction, the structure of the underground railway line, such as stations and intervals along the subway line, is limited by environmental factors, and sometimes the condition of track panel wells cannot be excavated right above the structure of the underground railway line, such as stations and intervals along the subway line are just below ground roads, and the ground roads cannot be occupied for a long time for construction. The track panel system of the present application is applicable to this situation.
Example one
FIG. 1 is a top view of a track panel well system according to an embodiment of the present application; FIG. 2 is a cross-sectional view A-A of the track panel well system shown in FIG. 1.
As shown in fig. 1 and 2, a track panel well system of an embodiment of the present application includes:
the track panel well 11 is arranged on the side of the underground line of the subway, and faces downwards from the ground; wherein the well mouth 111 of the track panel well is formed at the ground, and the well mouth 111 of the track panel well is used for placing the track panel from top to bottom;
and the side channel 12 is positioned below the ground, one end of the side channel 12 is communicated with the track panel well 11, and the other end of the side channel is used for being communicated with the underground railway line 2.
The section of track well system of this application embodiment, section of track well set up the side at subway underground line, through setting up the side passageway under the ground, with section of track well and subway underground line intercommunication. Like this, the section of track well is not just set up on subway underground line's structure, but set up the side at subway underground line's structure, especially can be applicable to the top of subway underground line and can't occupy, just in time is the condition of ground road like subway underground line's top. The section of track well sets up the side at subway underground line, and the selection of position can be selected according to the ground condition, can communicate section of track well and subway underground line through the side passageway. When the section of track well system of this application embodiment is used to the needs and is spread the rail, at first place down the section of track from the well head top-down of section of track well, later, remove the section of track well along side passageway, remove to the subway underground line from section of track well position, finally reach the position that needs to lay the section of track. The track panel well system of the embodiment of the application has the advantages of simple structure and convenience in construction, and can be used for digging track panel wells directly above the structure of the underground railway line, such as a ground road directly above a station and an interval along the subway line.
In practice, this is shown in FIG. 1. The side passage 12 is used for being communicated with the underground railway line 2 in an oblique mode.
Because the length of the track panel is longer, if the side passage is orthogonally communicated with the underground line of the subway, a right-angled turn can be generated at the orthogonal position, and the right-angled turn is not beneficial to steering the track panel. Therefore, the side channel and the underground line of the subway are in oblique crossing, so that the corner with the angle far larger than a right angle is formed at the oblique crossing position, the turning is convenient, the track laying progress can be accelerated, and the track laying cost is reduced.
In practice, the side channels are linear side channels, or curvilinear side channels.
The side channel is obliquely crossed with the underground line of the subway, and the side channel can be a linear side channel or a curved side channel. The shape of the side passage can be selected according to the position of the track panel well and the position of the underground line of the subway.
In practice, the width of the side channels is greater than the width of the track panel;
the length of the wellhead of the track panel well is larger than that of the track panel, and the width of the wellhead of the track panel well is larger than that of the track panel;
as shown in fig. 1, the range of the oblique crossing angle between the side passage 12 and the underground subway line 2 is greater than or equal to 110 degrees and less than or equal to 140 degrees.

The length of the well mouth of the track panel well is larger than that of the track panel, the width of the well mouth of the track panel well is larger than that of the track panel, namely the well mouth of the track panel well is slightly larger than the size of the track panel, and the requirement that the track panel is hoisted from the well mouth of the track panel well from top to bottom can be met.
The larger the angle of the side channel and the underground line of the subway is, the closer the side channel is to a straight line, the better the paving vehicle can walk, but the distance is wasted; the smaller the angle of the oblique crossing is, the greater the difficulty of turning the track laying vehicle is, and the shorter the distance is. The skew angle between the cross line between the tunnels and the track laying line needs to be selected according to the conditions of a construction site.
In an implementation, the track panel well system further comprises:
a transport rail 123, said transport rail 123 being disposed within said section bar well and said side channel 12; wherein the direction of the transportation rail 123 is consistent with the direction of the side channel 12;
and the rail paving vehicle 13 is placed above the transportation rail 123 and can move along the transportation rail 123.
After the track laying vehicle is moved to the position of the track panel well, the track panel is placed on the track laying vehicle from top to bottom at the wellhead of the track panel well, the track laying vehicle moves along the transportation track, and then the track laying vehicle can enter the underground line of the subway and move to the preset track laying position for track laying.
When the transport rail is curved, the radius of curvature is not less than 100 meters.

And the transition line in the tunnel is used for communicating two adjacent first track laying lines and is in oblique crossing connection. Like this, the railcar can move the first track laying circuit that is close to the transportation rail from the transportation rail, and other first track laying circuit is entered into to the cross-over in the rethread tunnel, realizes that the railcar moves each first track laying circuit, paves the rail.
When there are a plurality of intra-tunnel crossovers, the intra-tunnel crossovers may be connected substantially in the shape of a diagonal line or a curve, or may be arranged at intervals. The two modes can be selected according to the space of the site.
In implementation, the value range of the skew angle between the transition line in the tunnel and the first track laying line is greater than or equal to 110 degrees and less than or equal to 160 degrees.
The larger the angle of the skew is, the closer to a straight line is, the better the paving vehicle walks, but the distance is wasted; the smaller the angle of the oblique crossing is, the greater the difficulty of turning the track laying vehicle is, and the shorter the distance is. The skew angle between the cross line in the tunnel and the track laying line needs to be selected according to the conditions of a construction site.

And the cross lines between the tunnels are arranged in the channels between the tunnels and are used for obliquely crossing with the two adjacent second track laying lines. The communication between the second tunnels is realized through the tunnel-to-tunnel passage. Because the cross-over line between the tunnels and the second track laying line close to the transportation rail are in oblique crossing, the track laying vehicle can move to the first track laying line close to the transportation rail from the transportation rail and then enter other second track laying lines through the cross-over line between the tunnels, so that the track laying vehicle can move to each second track laying line to lay tracks.
