Description

Technical Field

[0001] The invention belongs to the technical field of railway line drainage structures, and in particular relates to a drainage structure crossing a track at a level crossing. Background Art

[0002] In the construction of railway lines, level crossings with roads are inevitable. There are generally drainage ditches or irrigation ditches on both sides of the road. The height difference between the bottom of the drainage ditch or irrigation ditch and the road surface is about 0.4 to 0.6m. Therefore, transverse drainage ditches are generally set at the level crossings between railways and roads to ensure the smooth flow of the road side drainage system.

[0003] The top surface of the existing transverse drainage ditch is about 0.4 to 0.8 m away from the track surface. When the road intersects the sightseeing train track plane, it is difficult for the transverse drainage ditch to ensure the smooth flow of the existing roadside drainage system. It is usually necessary to relocate the existing ditch or the road to meet the ditch elevation requirements.

[0004] Due to its characteristics, the sightseeing train system is mostly level with the roads along the line. If traditional horizontal drainage ditches are used to connect the ditches at both ends of the track, it will lead to a large number of ditch and road relocation projects, which will require large investments and have a great impact on the existing water system, which is not conducive to road traffic. Summary of the invention

[0005] In response to one or more of the above defects or improvement needs of the prior art, the present invention provides a drainage structure that crosses the track at a level crossing. It can meet the needs of the ditches on both sides of the road crossing the sightseeing train line without changing the ditches or raising the road surface elevation, thereby ensuring the smooth flow of the drainage system, and it also has the function of bearing part of the track structure load and taking into account the function of the sleepers.

[0010] As a further improvement of the present invention, the supporting structure includes two vertical plates, and the two vertical plates are respectively arranged tightly against the inner walls on both sides of the second ditch section.

[0011] As a further improvement of the present invention, rail anchor bolt and rail pad installation positions are reserved on the first sleeper.

[0012] As a further improvement of the present invention, the supporting structure also includes a bottom plate, which is arranged at the bottom of the second ditch section, and the bottom of the vertical plate is fixedly connected to the bottom plate. A plurality of spaced-apart vertical plates are combined with the bottom plate to form at least one drainage trough, and the drainage trough is connected to the first ditch section on both sides thereof.

[0013] As a further improvement of the present invention, it further comprises a top plate, which is arranged between two adjacent vertical plates, and two ends of which are respectively overlapped on the tops of the two vertical plates.

[0034] See also Figure 1 to Figure 3 The drainage structure crossing the track at the level crossing in the embodiment of the present invention is applied to the level crossing 9 of the track 7 and the road 8, which has both drainage and sleeper functions. Without changing the ditch and raising the road surface elevation of the road 8, the drainage structure can meet the needs of the side drainage ditch or irrigation ditch of the road 8 crossing the track 7 line, ensuring the smooth flow of the drainage system, and has the function of bearing part of the track structure load and taking into account the sleeper.

[0035] Specifically, Figure 1 As shown in the figure, a level crossing 9 is arranged at the intersection of the track 7 and the road 8. At the same time, a first ditch section 1 is arranged on both sides of the level crossing 9, and the first ditch section 1 extends along the road 8 and is arranged on at least one side of the road 8; at the same time, a second ditch section 2 is arranged along the track 7 at the level crossing 9, and both ends of the second ditch section 2 are respectively connected to the first ditch sections 1 on both sides of the level crossing 9.

[0036] Furthermore, a support structure 3 is provided in the second ditch section 2, which extends along the road 8, and the extension length is generally not less than the lateral width of the roadbed base 10 of the track 7. The water in the second ditch section 2 passes through the side or inside of the support structure 3 without affecting the water flow between the second ditch section 2 and the first ditch section 1.

[0037] At the same time, at least one sleeper installation position is arranged on the top of the supporting structure 3, and the sleeper installation position is at the same height as the sleeper installation position along the track 7; or, at least one first sleeper 304 integrally formed with the supporting structure 3 can be arranged on the top of the supporting structure 3, and the first sleeper 304 is at the same height as the second sleeper 701 laid along the track 7, forming an integral sleeper structure, and then when the train passes through the second ditch section 2, the load of the track 7 is directly borne by the supporting structure 3, and at the same time, the elevation of the second ditch section 2 is ensured to be at the same height as the bottom surface of the second sleeper 701, which can effectively ensure that the flow surface of the existing ditch does not change, and reduce the amount of engineering work for relocating the ditch and the road 8.

[0038] Preferably, rail anchor bolts and rail pad installation positions are reserved on the first sleeper 304 to facilitate fixing the rails 702 together with rail fasteners during track laying.

[0039] Preferably, the support structure 3 includes at least one vertical plate 301, and a first rail sleeper 304 is arranged on the top of each vertical plate 301. It can be known that when the lateral width of the second ditch section 2 is narrow, a vertical plate 301 can be arranged in the support structure 3, and the vertical plate 301 can be arranged at the center line of the second ditch section 2, and the water flow in the second ditch section 2 can flow from both sides of the vertical plate 301; when the lateral width of the second ditch section 2 is wide, multiple vertical plates 301 can be arranged at intervals along the lateral direction of the second ditch section 2, and a first rail sleeper 304 is arranged on the top of each vertical plate 301 to meet the load support of the rail 702.

[0040] like Figure 2 In the preferred embodiment shown, two vertical plates 301 are arranged in the second water ditch section 2 , and the two vertical plates 301 are respectively arranged tightly along the inner walls on both sides of the second water ditch section 2 .

[0041] Preferably, the support structure 3 further includes a bottom plate 302, which is arranged at the bottom of the second water ditch section 2, and the bottoms of the vertical plates 301 are fixedly connected to the bottom plate 302 to increase the support surface of the vertical plates 301 and improve the support stability of the support structure 3. When multiple vertical plates 301 are provided, multiple vertical plates 301 arranged at intervals are combined with the bottom plate 302 to form at least one drainage groove 305, and the drainage groove 305 is connected to the first water ditch sections 1 on both sides thereof, and water can flow through the drainage groove 305.

[0042] like Figure 2 In the preferred embodiment shown, two vertical plates 301 are combined with a bottom plate 302 to form a U-shaped support structure 3, and a drainage groove 305 is formed in the middle of the U-shaped support structure 3. To ensure the force stability of the support structure 3, the width of the support structure 3 along the line direction of the track 7 is generally not more than 1m, the width of the vertical plates 301 along the line direction of the track 7 is generally 0.1 to 0.2m, and the width of the drainage groove 305 along the line direction of the track 7 is generally 0.4 to 0.6m.

[0043] Preferably, the support structure 3 further includes a top plate 303, which is disposed between two adjacent vertical plates 301, and whose two ends are respectively overlapped on the tops of the two vertical plates 301 to close the top of the drainage groove 305 to prevent debris from falling into the drainage groove 305.

[0044] Preferably, since the drainage structure in the present invention takes into account the function of the sleeper and needs to withstand the load of passing trains, a drainage roadbed base 11 is also provided below the position of the track roadbed base 10 corresponding to the supporting structure 3, and the drainage roadbed base 11 has a longitudinal extension length of not less than 3 times the longitudinal width of the supporting structure 3 along the track 7, and a lateral extension width along the track 7 is consistent with the roadbed base 10, so as to ensure the bearing capacity of the base and avoid deformation and damage of the drainage trough 305 due to instability or deformation of the base.

[0045] Preferably, if Figure 3 As shown in the figure, a cover plate 4 is arranged on the top of one end of the first ditch section 1 close to the level crossing 9, and the cover plate 4 is in contact with the support structure 3 to ensure the driving and pedestrian safety of the level crossing 9 section, and prevent debris from falling into the first ditch section and causing blockage, thereby causing the level crossing 9 to be unable to pass normally.

[0046] Further preferably, at least one filter screen 6 is provided along the longitudinal direction of the road 8 on the side of the cover plate 4 away from the level crossing 9. The filter screen 6 is a steel filter screen to separate debris such as tree branches and prevent the debris from entering the drainage trough 305 and forming a blockage.

[0047] Preferably, a sump 5 is also provided in the first ditch section 1, and the top of the sump 5 is connected to the bottom of the first ditch section 1 to collect the sediment in the first ditch section 1 and prevent the sediment in the first ditch section 1 from flowing into the drainage trough 305 and causing the drainage trough 305 to be blocked. It is further preferred that the sump 5 is not less than 4m away from the center line of the railway track 7 to facilitate dredging.

[0048] The drainage structure crossing the track at the level crossing in the present invention integrates the track and the drainage structure, raises the ditch bottom elevation when the drainage structure crosses the track, optimizes the drainage system of the intersection section of the drainage structure and the sightseeing train, and improves the drainage capacity.
