Abstract
Description
Technical Field
[0001] The invention relates to the technical field of road drainage, and in particular to an open-cut tunnel anti-rainstorm structure. Background Art
[0002] With the rapid development of the national economy, the number of cars owned by the people continues to increase, and the burden of urban road traffic is becoming heavier. In order to solve the problem of road traffic congestion, roads have developed from simple plane traffic to three-dimensional traffic, which is generally achieved by building overpasses or underpasses. At the same time, as the landscape requirements of cities are getting higher and higher, underpasses have highlighted their advantages in this regard, and therefore have been increasingly promoted and applied.
[0003] In recent years, with the frequent occurrence of rainstorms and extreme weather, urban tunnels, as underground roads, are one of the infrastructures most vulnerable to extreme weather. In heavy rain, rainstorms and other heavy rainfall weather, too much rainwater enters the tunnel. If it cannot be drained out of the tunnel in time, it will affect the normal operation of the tunnel, causing traffic paralysis and heavy losses.
[0004] Therefore, how to design a rainstorm prevention structure for a tunnel to achieve drainage and discharge of rainwater and ensure the normal operation of the tunnel has become a technical problem that technical personnel in this field urgently need to solve. Summary of the invention
[0005] In view of the above-mentioned defects of the prior art, the present invention provides an open-cut tunnel anti-rainstorm structure, the purpose of which is to achieve the following.
[0006] To achieve the above technical objectives, the present invention provides an open-cut tunnel anti-rainstorm structure, including a tunnel body, wherein the tunnel body is provided with transverse drainage ditches on the ground at the exit and entrance, respectively, and the transverse drainage ditches are connected to the cavity regulating tank through an overflow pipe.
[0007] Preferably, the cavity regulating reservoir is located at the top of the buried section of the tunnel body.
[0008] Preferably, the cavity regulating reservoir and the overflow pipe are both buried underground.
[0009] Preferably, the top of the transverse drainage ditch is flush with the top of the ground.
[0010] Beneficial effects of the present invention:
[0011] Due to the above structural design, the coordinated arrangement of the transverse drainage ditch and the overflow pipe in the present invention can drain rainwater into the cavity storage tank in heavy rain or rainstorm weather, avoiding rainwater from entering the tunnel body, thereby ensuring the normal operation of the tunnel body. BRIEF DESCRIPTION OF THE DRAWINGS
[0012] Figure 1 It is a schematic diagram of the structure of the present invention.
[0013] In the figure: 1 tunnel body, 2 cavity regulating reservoir, 3 overflow pipe, 4 transverse drainage ditch. DETAILED DESCRIPTION
[0014] The concept, specific structure and technical effects of the present invention will be further described below in conjunction with the accompanying drawings to fully understand the purpose, characteristics and effects of the present invention.
[0015] Example:
[0016] like Figure 1 As shown, the open-cut tunnel anti-rainstorm structure includes a tunnel body 1. The tunnel body 1 is provided with transverse drainage ditches 4 on the ground at the exit and entrance respectively. The transverse drainage ditches 4 are connected to the cavity regulating reservoir 2 through an overflow pipe 3.
[0017] The main innovation of the present invention is that in heavy rain weather, when the transverse drainage ditch 4 cannot drain water in time, rainwater can be discharged into the cavity regulating reservoir 2 through the overflow pipe 2.
[0018] The cavity regulating reservoir 2 and the overflow pipe 3 are both buried underground.
[0019] The top of the transverse drainage ditch 4 is flush with the top of the ground.
[0020] In some embodiments, the cavity storage tank 2 is located at the top of the buried section of the tunnel body 1 .
[0021] Working principle of the present invention:
[0022] When the rainfall is light, the transverse drainage ditch 4 drains water normally; when the rainfall is heavy and the transverse drainage ditch 4 cannot discharge the rainwater in time, the rainwater will be discharged into the cavity regulating reservoir 2 through the overflow pipe 3, avoiding the rainwater from entering the tunnel body 1 and affecting the normal operation of the tunnel.
[0023] The preferred specific embodiments of the present invention are described in detail above. It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work. Therefore, any technical solution that can be obtained by a person skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should be within the scope of protection determined by the claims.
