Description

TECHNICAL FIELD

[0001] The present application belongs to the field of bridge structure construction, and particularly relates to a railway double-layer frame pier drainage structure. BACKGROUND

[0002] In the construction of railway bridges, due to the complex existing and newly planned road pipelines in some areas, small-angle intersection points of bridges inevitably appear more and more frequently. Frame pier structures are favored by bridge designers due to their flexible and reasonable spatial arrangement, and are applied more and more widely in high-speed railway bridges.

[0003] In recent years, with the increasing in-depth research on frame pier structures, bridge designers attempt to replace the conventional design scheme of the upper frame pier combined with the lower ordinary pier by the railway double-layer frame pier scheme to solve the problem of small-angle skew line arrangement of newly built railway lines.

[0004] However, in the actual use of the railway double-layer frame pier, it is found that the drainage method thereof needs to be improved. Most of the existing railway double-layer frame piers adopt the drainage method of ordinary frame piers, that is, a drainage slope is arranged on the upper beam of the double-layer frame pier in the line direction, so that the rainwater flows out of the top of the beam along the slope. However, when the temperature is low in winter, the rainwater on the upper beam flows to the outside of the beam in the line direction and freezes, and the ice falling from the frozen rainwater may affect the driving of the lower line.

[0005] In addition, the beam and the pier body of the double-layer frame pier are usually provided with a box beam drainage pipe to drain the accumulated water on the top of the box beam to the ground through the drainage pipe. The box beam drainage pipe is usually fixed to the side surface of the double-layer frame pier by a pipe clamp and a matched bolt. However, the pier column of the double-layer frame pier is relatively high, and the wind load acting on the drainage pipe is large. In addition, the pipe clamp bolt is easily rusted by rainwater all the year round, which increases the risk of falling of the drainage pipe and affects the driving of the lower line. SUMMARY

[0006] The present application is proposed to solve the problems existing in the prior art, and the purpose is to provide a railway double-layer frame pier drainage structure.

[0007] The technical scheme of the present application is as follows: a railway double-layer frame pier drainage structure, comprising a lower beam and an upper beam, the lower beam and the upper beam being parallel to each other, a lower beam body being arranged at the upper end of the lower beam, an upper beam body being arranged at the upper end of the upper beam, a lower drainage structure being arranged at the upper end of the lower beam, an upper drainage structure being arranged at the upper end of the upper beam, and a vertical drainage structure being arranged outside the pier column of the double-layer frame pier.

[0008] Furthermore, the upper drainage structure comprises a surface drainage structure and a beam body drainage structure, and the surface drainage structure and the beam body drainage structure are comprehensively drained.

[0009] Further, the surface drainage structure comprises a water retaining platform, the water retaining platform is parallel to the upper transverse beam.

[0010] Further, the two water retaining platforms and the upper transverse beam form a drainage groove which is open at the top and two sides.

[0011] Further, the beam body drainage structure comprises an upper layer left collecting pipe and an upper layer right collecting pipe, the upper layer beam body is provided with a reserved drainage channel during pouring, and the upper layer left collecting pipe and the upper layer right collecting pipe are respectively communicated with the reserved drainage channel of the upper layer beam body, so as to collect water on the upper layer beam body into the upper layer left collecting pipe and the upper layer right collecting pipe.

[0012] Further, the upper layer left collecting pipe and the upper layer right collecting pipe are communicated with an upper layer main pipe, and the upper layer main pipe realizes the confluence of the upper layer left collecting pipe and the upper layer right collecting pipe.

[0013] Further, the upper end of the upper transverse beam is provided with an upper transverse beam supporting cushion stone which supports the upper layer beam body.

[0014] Further, the upper layer main pipe is further bent and transitioned upwards and downwards.

[0015] Further, the lower transverse beam and the upper transverse beam are supported by the pier column and are arranged between the two side pier columns.

[0016] Further, a drainage pipe is arranged outside the pier column and is communicated with the upper layer main pipe, so as to realize the total confluence of drainage.

[0017] The beneficial effects of the present application are as follows:

[0018] The present application sets the water retaining platform outside the upper transverse beam, so that the surface water on the upper transverse beam is drained from both ends along the water retaining platform, thereby solving the problem that the lower layer line driving may be affected by the ice falling from the upper layer transverse beam of the double-layer frame pier in winter.

[0019] The present application adopts the upper and lower layer combined drainage pipe, arranges the drainage pipe along the top surface of the transverse beam of the double-layer frame pier and the outside of the pier column, solves the problem that the lower layer line driving may be affected by the falling of the drainage pipe of the frame pier, and changes the position of the drainage pipe between the water retaining platforms, thereby reducing the load effect of the longitudinal wind force on the drainage pipe and reducing the risk of damage of the drainage pipe in a strong wind environment.
