Background

The roadbed is a foundation of a track or a road surface, is a geotechnical structure formed by excavation or filling, and has the main functions of providing necessary conditions for track or road surface paving and train or driving operation, bearing static load and dynamic load of the track and rolling stock or road surface and traffic load, and simultaneously transmitting and diffusing the load to the deep part of the foundation. On the vertical section, the roadbed must ensure the elevation required by the line; on a plane, the roadbed, the bridge and the tunnel are connected to form a complete through line.

At present, the existing roadbed drainage structure does not support the installation position of the bushing plate, the phenomenon that the installation position of the bushing plate collapses is easily caused when a vehicle runs on the bushing plate, the probability of damage of the bushing plate and the installation position of the bushing plate is increased, the limiting plate is inconvenient to replace, and the protection effect of the drainage structure in the use process is reduced. For this reason, new solutions need to be designed to solve.

Disclosure of Invention

The utility model aims to provide a roadbed drainage structure which solves the problems in the background art.

In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides a road bed drainage structures, includes the road bed body, the inside of road bed body is provided with the water drainage tank, the inside of water drainage tank is provided with the support frame, be provided with mounting panel and baffle on the support frame, mounting panel fixed connection be in the bottom of support frame, and through the screw thread with the bottom demountable installation of water drainage tank, baffle fixed connection is in the top of support frame, the top of baffle is provided with the limiting plate, the limiting plate is connected with the thread bush through fixing bolt, the top of limiting plate is provided with the bushing.

Through adopting above-mentioned technical scheme, effectually realized supporting the installation position of bushing, avoided the vehicle to go and lead to its installation position phenomenon that collapses on the bushing, reduced the probability that bushing and installation position damaged, still conveniently change the limiting plate moreover, improved the protection effect of drainage structures in the use.

As an alternative of the technical scheme, the width of the bushing plate is identical to the width of the drainage groove, and the bushing plate is movably connected with the upper surface of the limiting plate.

Through adopting above-mentioned technical scheme, conveniently let the bushing shelter from the top of water drainage tank.

As an alternative of the technical scheme of the application, the threaded sleeve is fixedly installed in the roadbed body, and symmetrically arranged on two sides of the drainage groove.

By adopting the technical scheme, the firmness of the thread bush and the inside of the roadbed body is improved.

As an alternative of the technical solution of the present application, the fixing bolt passes through the inside of the limiting plate and is connected with the inside of the thread bush through threads.

By adopting the technical scheme, the fixing bolt and the threaded sleeve are conveniently disassembled and assembled.

As an alternative of the technical scheme of the application, the upper surface of the baffle is propped against the bottom of the limiting plate and is movably connected with the bottom of the limiting plate.

Through adopting above-mentioned technical scheme, conveniently let the baffle support the limiting plate.

Compared with the prior art, the beneficial effects of the technical scheme are as follows:

according to the utility model, through the combination of the support frame, the mounting plate, the baffle, the limiting plate, the fixing bolts, the threaded sleeve and the bushing, the mounting part of the bushing is effectively supported, the phenomenon that the mounting part of the bushing collapses due to the fact that a vehicle runs on the bushing is avoided, the probability of damage of the bushing and the mounting part of the bushing is reduced, the limiting plate is convenient to replace, and the protection effect of the drainage structure in the use process is improved.

Drawings

Other features, objects and advantages of the present utility model will become more apparent upon reading of the detailed description of non-limiting embodiments, given with reference to the accompanying drawings in which:

FIG. 1 is a front view of a drainage structure for roadbed according to the present utility model;

fig. 2 is a partial enlarged view of a drainage structure for roadbed according to the present utility model.

In the figure: 1. a roadbed body; 11. a drainage channel; 12. a support frame; 13. a mounting plate; 14. a baffle; 15. a limiting plate; 16. a fixing bolt; 17. a thread sleeve; 18. and a bushing plate.

Detailed Description

Referring to fig. 1-2, the present utility model provides a technical solution: the utility model provides a road bed drainage structure, including road bed body 1, the inside of road bed body 1 is provided with water drainage tank 11, the inside of water drainage tank 11 is provided with support frame 12, be provided with mounting panel 13 and baffle 14 on the support frame 12, mounting panel 13 fixed connection is in the bottom of support frame 12, and install with the bottom dismantlement of water drainage tank 11 through the screw thread, baffle 14 fixed connection is on the top of support frame 12, the upper surface butt of baffle 14 is in the bottom of limiting plate 15, and with the bottom swing joint of limiting plate 15, the top of baffle 14 is provided with limiting plate 15, limiting plate 15 is connected with thread bush 17 through fixing bolt 16, fixing bolt 16 passes the inside of limiting plate 15, and be connected with the inside of thread bush 17 through the screw thread, thread bush 17 fixed mounting is in the inside of road bed body 1, and the symmetry sets up in the inside both sides of water drainage tank 11, the top of limiting plate 15 is provided with bushing 18, the width of bushing 18 coincides with the width of water drainage tank 11, and with the upper surface swing joint of limiting plate 15.

In this kind of technical scheme, conveniently support the installation position of bushing 18, avoided the vehicle to go on bushing 18 and lead to its installation position phenomenon of collapsing, reduced bushing 18 and the probability that installation position damaged, but also conveniently change limiting plate 15, improved the protection effect of drainage structures in the use.

Working principle: when the vehicle is running on the drain plate 18 of the drainage structure, the pressure born by the drain plate 18 is transmitted to the limiting plate 15, at this time, the limiting plate 15 is supported by the baffle plate 14, meanwhile, the baffle plate 14 is supported by the support frame 12, when the limiting plate 15 is deformed and replaced, an operator can directly screw out the fixing bolt 16 from the screw sleeve 17, and then the replaced limiting plate 15 is installed above the baffle plate 14.
