Description

Technical Field

[0001] The invention relates to the technical field of road gullies, and in particular to a gully structure. Background Art

[0002] In the design of urban drainage pipe network, the rainwater inlet is the main structure for collecting rainwater. The rainwater inlet in the prior art is generally wide and extends to the outside of the road edge.

[0003] When the rainwater inlet is set on the roadway, its structure will bear the rolling of vehicles for a long time, which may easily lead to damage, thus affecting the normal operation of vehicles on the roadway.

[0004] Therefore, how to design a rainwater inlet structure to avoid being crushed by vehicles and ensure the normal operation of the roadway 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 a gully structure, the purpose of which is to shrink the gully to the inner side of the curb to avoid being crushed by vehicles.

[0006] To achieve the above technical objectives, the present invention provides a rainwater inlet structure, comprising a fan-shaped drainage bucket, wherein the fan-shaped drainage bucket is retracted to the inner side of the road edge;

[0007] The fan-shaped drainage bucket is provided with a grille on the top and a drainage pipe on the bottom;

[0008] One end of the drainage pipe away from the fan-shaped drainage bucket is connected to the drainage well.

[0009] Preferably, the drain pipe is connected to the bottom center of the fan-shaped drain bucket, and the curved surfaces of the fan-shaped drain bucket on both sides of the drain pipe are in the shape of the fastest curve.

[0010] Preferably, the arc of the brachistochrone curve satisfies the following set of equations:

[0011]

[0012] Where: a is the length of the installation slot; θ is the angle between the particle motion velocity and the arc normal.

[0013] Preferably, the openings on the grille are arranged at equal intervals.

[0014] Beneficial effects of the present invention:

[0015] Due to the structural design, the fan-shaped drainage bucket of the present invention can be retracted to the inner side of the curb to avoid being crushed by vehicles and not affecting the roadway.

[0016] Furthermore, the present invention can speed up the drainage by setting the two side walls of the fan-shaped drainage bucket in a curved shape, thereby avoiding the occurrence of water accumulation on the road surface and further ensuring the normal operation of the lane.

[0018] Figure 2 for Figure 1 Schematic diagram of the cross-sectional structure.

[0019] In the figure: 1 fan-shaped drainage bucket, 2 grille, 3 drainage pipe. DETAILED DESCRIPTION

[0020] 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.

[0021] Example:

[0022] like Figure 1-Figure 2 As shown, a specific embodiment of the rainwater outlet structure of the present invention includes a fan-shaped drainage bucket 1, which is installed in a mounting groove reserved on the ground surface and retracted to the inner side of the road edge.

[0023] A grille 2 is arranged on the top of the fan-shaped drainage bucket 1, and a drainage pipe 3 is arranged on the bottom. One end of the drainage pipe 3 away from the fan-shaped drainage bucket 1 is connected to the drainage well.

[0024] The main innovations of the present invention are:

[0025] The size of the fan-shaped drainage scoop 1 is longer and narrower than that of the traditional drainage scoop, so that the fan-shaped drainage scoop 1 is retracted to the inner side of the curb and does not affect the roadway.

[0026] Specifically, the drain pipe 3 is connected to the bottom center of the fan-shaped drain bucket 1, that is, the end of the fan-shaped drain bucket 1; the curved surface of the fan-shaped drain bucket 1 on both sides of the drain pipe 3 is in the shape of the fastest curve, and the curvature of the fastest curve satisfies the following equation group:

[0027]

[0028] Where a is the length of the installation slot; θ is the angle between the particle motion velocity and the normal of the arc.

[0029] The openings on the grille 2 are arranged at equal intervals.

[0030] Example 1:

[0031] The length of the installation groove is 100 cm, the width is 20 cm, θ is 30°, the vertex (starting point) of the arc is h1≈2 cm, the low point (end point) of the arc is h2≈14 cm, and h1 / h2=0.14;

[0032] Example 2:

[0033] The length of the installation slot is 100 cm, the width is 20 cm, θ is 45°, the apex (starting point) of the arc is h1≈8 cm, the low point (end point) of the arc is h2≈30 cm, and h1 / h2≈0.27;

[0034] Example 3:

[0035] The length of the installation groove is 100 cm, the width is 20 cm, θ is 60°, the apex (starting point) of the arc is h1≈18 cm, the low point (end point) of the arc is h2≈50 cm, and h1 / h2≈0.36.

[0036] In summary, when the length of the installation groove is fixed, the larger the ratio of h1 to h2, that is, the smaller the slope between the vertex (starting point) of the arc and the low point (end point) of the arc, that is, the slower the speed of rainwater flow.

[0037] The working principle and use process of the present invention:

[0038] The fan-shaped drainage bucket 1 is installed in the installation groove reserved on the ground surface, and the drainage pipe 3 is connected to the wellhead of the drainage well. Since the size of the fan-shaped drainage bucket 1 is longer and narrower than the drainage bucket in the prior art, the fan-shaped drainage bucket is retracted to the inner side of the curb and does not affect the roadway.

[0039] The curvature of the curve in the fan-shaped drainage bucket 1 is calculated and determined according to the use requirements, which can speed up the drainage speed and avoid the occurrence of water accumulation on the road, thereby affecting the normal operation of the lane.

[0040] 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.
