[0002] In the construction of industrial enterprises, off-site roads and their drainage are important links, especially when the elevation of the factory gate is lower than the natural ground. The off-site roads slope downward toward the gate. In rainy seasons, if no measures are taken to enhance drainage, rainwater on the road surface will easily flow back into the factory, causing travel difficulties for people inside and outside the factory, and even causing the factory to face the threat of waterlogging, affecting the normal operation of industrial enterprises. Based on the production characteristics of industrial enterprises, most of the transportation vehicles are heavy-loaded vehicles. Therefore, the design of roads and drainage facilities must consider the structural bearing capacity. Utility Model Content

[0027] The following is combined with Figure 1 -Attached Figure 5 The utility model is further illustrated with reference to the accompanying drawings and embodiments.

[0028] As attached Figure 1 -Attached Figure 5 As shown, the utility model provides a drainage structure for use on off-site roads of industrial enterprises, including a water trough 1 and a cushion layer 2, a prefabricated reinforced concrete cover plate 3, a steel grating cover plate 4, a water trough corner guard 9, a prefabricated retaining stone 5, a retaining stone corner guard 8, a rubber strip 6 and an expansion joint 7.

[0029] Taking into account the need to ensure smooth drainage paths and effectively increase the water-passing cross-section, the drainage structure of the utility model is arranged at the lowest point of the longitudinal section elevation of the road outside the factory or near the factory gate to ensure that the drainage structure of the utility model is effectively connected with the existing drainage structures on both sides of the road and to prevent rainwater from flowing back into the factory.

[0030] In the attached Figure 1 In the illustrated embodiment, the top surface of the bottom plate of the water channel 1 is sloped toward both sides of the road and connected to the roadside drainage system, with a slope of not less than 0.3%.

[0031] In the attached Figure 2 In the embodiment shown, a cushion layer 2 is provided at the bottom of the water channel 1, with a thickness of 100mm, and each side is 100mm larger than the bottom plate size of the water channel 1. After the cushion layer 2 is poured, the water channel 1 is poured, and its cross-sectional size is determined by the road surface drainage requirements, and the top surface height is consistent with the top elevation of the civilized construction road surface; a tongue-and-groove groove is provided at the top of the water channel 1, and the height of the tongue-and-groove groove is the same as the thickness of the reinforced concrete prefabricated cover plate 3, and a water channel angle guard 9 is provided at the positive corner of the tongue-and-groove groove, and a finished angle steel can be used. In order to prevent the reinforced concrete prefabricated cover plate 3 from generating abnormal noise and vibration when a vehicle passes, the top of the tongue-and-groove groove of the water channel 1 is left with a groove of about 20mm×20mm, and before laying the reinforced concrete prefabricated cover plate 3, a rubber strip 6 is filled inside it.

[0032] In the attached Figures 3 to 5In the illustrated embodiment, the thickness and reinforcement of the precast reinforced concrete cover plate 3 are determined based on the required bearing capacity. The precast reinforced concrete cover plate 3 is provided with elliptical drainage holes at places avoiding the reinforcement, and the top of the cover plate around the drainage holes is chamfered to reduce damage to the top surface of the cover plate caused by long-term rolling of vehicles.

[0033] During the construction period, that is, before the asphalt pavement surface layer is laid, a precast reinforced concrete cover plate 3 is placed on the top of the water trough 1 after it is poured. Under this arrangement, the top surface heights of the water trough 1 and the precast reinforced concrete cover plate 3 are consistent with the top elevation of the civilized construction road surface, which can ensure the effective discharge of rainwater from the road surface and the smooth passage of vehicles during the construction period.

[0034] In the attached Figure 2 In the embodiment shown, the steel grille cover plate 4 can be a finished product with a hinge pin and a frame, which is convenient for opening the cover plate. Before the permanent asphalt pavement is laid, grooves are cut on the civilized construction pavement on both sides of the water trough 1, and prefabricated retaining stones 5 are installed. The prefabricated retaining stones 5 are provided with retaining stone corner guards 8 on the side of the water trough 1, and expansion joints 7 are provided near the permanent asphalt pavement. After the permanent asphalt pavement is completed, the steel grille cover plate 4 is laid on the top of the water trough 1 and the reinforced concrete prefabricated cover plate 3. Under this arrangement, the top surface heights of the steel grille cover plate 4 and the prefabricated retaining stones 5 are consistent with the top elevation of the permanent asphalt pavement, which can ensure the effective discharge of rainwater from the road surface and the smooth passage of vehicles during the operation of the project.

[0035] The user may bring his own steel chisel to open the steel grille cover 4. During the operation of the project, if sudden heavy rain causes water accumulation at low points on the road outside the factory, the double-layer cover may be opened to increase the water flow section. During the construction and operation, the water trough 1 should be cleaned and maintained regularly to ensure smooth drainage.

[0036] The above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, according to the technical scheme and utility model concept of the utility model, shall be covered by the protection scope of the utility model.
