Description
Technical field
The present invention relates to temporary track fixed system and its construction in a kind of tunnel.
Background technology
At present during shield-tunneling construction, most of arcs being combined using battery truck sleeper with bogie wheels sleeper
Sleeper, as shield-tunneling construction promotes, the sleeper that will be disengaged from chassis removes left and right wheel sleeper in pairs, and place mat is before shield-tunneling construction
Enter direction and make the follow-up chassis support of new shield, and remainder is then used as battery truck sleeper after removing.This type sleeper is present
Following shortcoming：Single weight is big, wastes raw material, and integral reinforcing is difficult.Battery truck sleeper and chassis sleeper are using 10mm
Steel plate is processed for former material, and single battery truck sleeper weight reaches 11.6kg, on the one hand made up to 30kg, bogie wheels sleeper
Into the waste of former material, another aspect 30kg weight is in tunnel, it is necessary to which two people cooperate in the short environment in shield body bottom
It could carry and be in place, cause the waste of personnel；Rail level is too high, causes battery truck operation unstable.After arc sleeper laying
Rail level is caused to raise so that battery truck rail level lifting 114mm, rail level is unstable, easily slides down, has in battery truck running
Potential safety hazard.Rail level is raised rear shield machine trolley distance from top tunnel edge distance and furthered, and easily collide friction, to construction
Quality brings hidden danger.
Above deficiency, it is to be improved.
The content of the invention
In order to overcome the shortcomings of existing technology, the present invention provides temporary track fixed system in a kind of tunnel and its applied
Work engineering method.
Technical solution of the present invention is as described below：
Temporary track fixed system in a kind of tunnel, including battery truck sleeper located at tunnel wall bottom and located at the battery truck
The chassis sleeper of sleeper both sides, the battery truck sleeper are connected with the chassis sleeper, the battery truck sleeper and the chassis
Sleeper is connected with the tunnel wall respectively, and battery truck track, two battery trucks are provided with above the battery truck sleeper both ends
Track is connected with the battery truck sleeper respectively, and the battery truck track presses close to the tunnel wall, is set on the chassis sleeper
There is trolley track, the trolley track is connected with the chassis sleeper.
Further, the battery truck sleeper includes the end sleeper at interlude sleeper and both ends, the end sleeper with
Battery truck track neck is provided between the interlude sleeper, the battery truck track is located in the battery truck track neck,
The battery truck track is connected with the battery truck sleeper.
Further, the bottom of the chassis sleeper is provided with the connector being connected with the battery truck sleeper, the connection
Part is connected with the chassis sleeper, and the connector is connected with the end sleeper.
Further, the horizontal segment on the top of the chassis sleeper is provided with two fixtures, the fixture with described
Track pillow connects, and is provided with trolley track neck between two fixtures, the trolley track is located at the trolley track card
In groove, the trolley track is connected with the chassis sleeper.
Further, the both sides of the battery truck sleeper are provided with that reinforcing bar is vertical to be connected, and the reinforcing bar is vertical even and the storage battery track
The end of pillow is by being welded to connect.
Further, the reinforcing bar is vertical even at interval of band iron is provided with 20m~30m, and the band iron is indulged with the reinforcing bar to be connected
By being welded to connect, the band iron is connected by segment bolt with the tunnel wall.
Further, the battery truck sleeper and the chassis sleeper are multiple.
It is another object of the present invention to provide a kind of construction of temporary track fixed system in tunnel, including：
S1：Measure the distance between battery truck wheel；
S2：Height of the battery truck sleeper apart from tunnel wall is calculated using round chord length；
S3：Measure the distance between bogie wheels；
S4：Measure the height of chassis；
S5：The height in tunnel is calculated according to design drawing；
S6：Under the precondition that chassis does not collide tunnel wall, chassis sleeper is calculated apart from tunnel wall using diameter of a circle
Highly；
S7：Chassis sleeper is calculated apart from the height and chassis sleeper of tunnel wall apart from the height of tunnel wall according to battery truck sleeper
With the relative position of battery truck sleeper；
S8：Trolley rail pillow and battery truck sleeper are installed.
Further, in S2, the length of battery truck tie, battery truck are calculated according to the distance between battery truck wheel
The length of sleeper is longer than the distance between battery truck wheel, the length of battery truck sleeper and the difference of the distance between battery truck wheel
For fixed value, you can the length of battery truck sleeper is calculated, because the distance at tunnel center to tunnel wall is round radius, you can
Tunnel center is calculated to the height of battery truck sleeper, then by round radius and the height phase at tunnel center to battery truck sleeper
Subtract, you can calculate battery truck sleeper to the height of tunnel wall, you can calculate height of the battery truck sleeper apart from tunnel wall.
Further, in S6, due to the distance between bogie wheels it has been determined that the height of chassis is it has been determined that work as chassis
Height when being contacted just with tunnel wall, the line between the end of the top of chassis and the chassis sleeper of opposite side is by circle
The heart, you can calculate the air line distance of both sides chassis sleeper, then utilize the radius of circle, you can calculate tunnel center to chassis
Sleeper height, round radius is subtracted each other with tunnel center to the height of chassis sleeper, that is, calculated chassis sleeper apart from tunnel
The height of road wall.
According to the present invention of such scheme, its advantage is, the present invention is calculated using the chord length of circle and determines structure chi
It is very little, battery truck track is pressed close to tunnel wall, highly shortened the distance between battery truck track and tunnel wall, reduce storage battery
The height in track face, so that battery truck operation becomes more steady.

The heart, you can calculate the air line distance of both sides chassis sleeper 3, then utilize the radius of circle, you can calculate tunnel center to platform
Track pillow 3 height, round radius is subtracted each other with tunnel center to the height of chassis sleeper 3, that is, calculated chassis sleeper 3 away from
From the height of tunnel wall 1.
As shown in figure 5, in S8, S81：Placing storage battery track pillow 2 is with placing trolley rail pillow 3, specially：Electricity is placed first
Bottle track pillow 2, then places trolley rail pillow 3, by the end of battery truck sleeper 2 and the end of chassis sleeper 3 in the both sides of battery truck sleeper 2
The connector 31 in portion connects.
S82：Placing storage battery track road 5 is specially with placing trolley track 6：Battery truck track 5 is placed on storage battery track
The both ends of pillow 2, trolley track 6 is placed on chassis sleeper 3.
S83：Place reinforcing bar and indulge and connect 4, be specially：After chassis sleeper 3 is removed, steel is placed in the both sides of battery truck sleeper 2
Flaccidity of tendon and muscle connects 4, and reinforcing bar is vertical even 4 to be fixedly connected with battery truck sleeper 2；At interval of 20~30m, in reinforcing bar, vertical company 4 passes through band iron and tunnel
Road wall 1 is fixedly connected.
It should be appreciated that for those of ordinary skills, can according to the above description be improved or converted,
And all these modifications and variations should all belong to the protection domain of appended claims of the present invention.
Exemplary description has been carried out to patent of the present invention above in conjunction with accompanying drawing, it is clear that the realization of patent of the present invention not by
