Abstract
The utility model discloses the interim transition of operation line steel sleeper in a kind of subway tunnel and open track structure, comprise steel sleeper, bearing and connecting rod, employing steel sleeper designs, between steel sleeper is longitudinal, connecting rod connects, form overall track structure, be convenient to install, dismounting, can realize bias, superelevation adjustment, stressed through safety inspection calculation meet operation security condition.
Description
Technical field
The utility model relates to interim twilight orbit construction applications, specifically after existing ballast bed structure is removed, meet Operational requirements and the interim transition steel sleeper track structure installing, set up.
Background technology
After operation line operational railway structure is abolished in subway tunnel, the Operational requirements of circuit be met, and train operation safety will be ensured.Therefore design have developed the interim transition steel sleeper track structure of one, substitutes existing railway roadbed, can realize bias, superelevation adjustment, and is convenient to install, dismantle, and ensures train safe operation.
Utility model content
The purpose of this utility model is to provide the interim twilight orbit structure of operation line steel sleeper in a kind of subway tunnel, recover temporary line and guarantee the requirement of circuit operation security, bias, superelevation adjustment can be realized while guarantee recovers circuit and circuit operation security, and be convenient to install, dismantle, effectively ensure that efficiency of construction and train operation safety.
The technical solution adopted in the utility model is as follows:
The interim twilight orbit structure of operation line steel sleeper in subway tunnel, include the hard-wired bearing of tunnel tube wall with both sides, between the bearing of both sides, erection has steel sleeper, adjustable link is connected with between two adjacent steel sleepers, described adjustable link includes the swivel nut be fixedly connected with both sides steel sleeper, and the double threaded screw matched with swivel nut.
Described tunnel tube wall is fixedly connected with by 4 setscrews with bearing.
Leave enough adjustment spaces between steel sleeper of the present utility model and bearing, be connected with connecting rod between steel sleeper with steel sleeper and ensure that steel sleeper track structure globality, it is characterized in that adopt steel sleeper design, stressed through safety inspection calculation meet safe operation condition; Bias, superelevation adjustment can be realized, and be convenient to install, dismantle, ensure train operation safety.
The utility model has the advantages that:
1, steel sleeper track structure is made up of three parts and comprises steel sleeper, bearing and connecting rod, and combining structure is convenient to substep and is installed, and meeting the short time sets up requirement;
2, steel sleeper track structure can realize track circuit bias, superelevation adjustment, connect with connecting rod between steel sleeper, ensure that the globality of steel sleeper track structure, stressed through safety inspection calculation meet safe operation condition, effectively raise operating efficiency and ensure that train operation safety.
Accompanying drawing explanation
Fig. 1 is steel sleeper cross-sectional drawing of the present utility model;
Fig. 2 is that steel sleeper of the present utility model connects plan view.
concrete implementation step
See accompanying drawing, the interim twilight orbit structure of operation line steel sleeper in subway tunnel, include bearing 2 hard-wired with the tunnel tube wall 1 of both sides, tunnel tube wall 1 is fixedly connected with by 4 setscrews with bearing 2, between the bearing of both sides, erection has steel sleeper 3, be connected with adjustable link 4 between two adjacent steel sleepers 3, adjustable link 4 includes the swivel nut be fixedly connected with both sides steel sleeper, and the double threaded screw matched with swivel nut.
Steel sleeper connected mode is described in detail below in conjunction with accompanying drawing:
In subway tunnel operation line rest the head on interim twilight orbit structure by steel sleeper, bearing and connecting rod three part form: 1) measurement and positioning steel sleeper support position; 2) by 4 setscrews, bearing is fixed on tube wall on tunnel tube wall; 3) steel sleeper is erected at itself and bearing are fixed with bolt by the bearing that fixes; 4) between two steel sleepers, an entirety is connected into connecting rod; 5) by steel rail laying on the track of steel sleeper, reach track after accurate adjustment and open requirement.
