[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0027] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.
[0028] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.
[0029] In the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.
[0030] In order to solve the problems existing in the prior art, such as Figure 1 and Figure 2 As shown, this embodiment provides a culvert drainage system for a power plant area, comprising a drainage ditch 2 located on one side of a plant road 1 and a rainwater grate 3 located between the plant road 1 and the drainage ditch 2, wherein the rainwater grate 3 is connected to the drainage ditch 2 via a connecting culvert 4; wherein the plant road 1 adopts a single-sided slope setting, and the drainage ditch 2 adopts a culvert setting.
[0031] In a specific implementation, there are multiple rainwater grates 3, which are evenly distributed on the bottom side of the slope of the factory road 1. For example, the distance between each rainwater grates 3 can be set to 15 to 25 meters, which can be set according to actual needs (such as local rainfall).
[0032] In a specific implementation, the interface position between the rainwater grate 3 and the concealed pipe 4 is set at a position at a preset height from the bottom of the rainwater grate.
[0033] The above settings have the following benefits:
[0034] The rainwater from the rainwater well first flows into the rainwater grate well and then connects to the drainage ditch through a concealed pipe. The interface of the concealed pipe is 200-300mm higher than the bottom of the rainwater grate well, which can play a simple sedimentation role and ensure that debris and heavy objects do not flow into the concealed pipe and cause blockage.
[0035] In a specific implementation, the diameter of the connecting concealed pipe ranges from 200 to 500 mm, and the connecting concealed pipe adopts a double-wall corrugated pipe or a steel pipe.
[0036] Specifically, a rainwater grate 5 is provided on the top of the rainwater grate well 3. In order to ensure smooth drainage during heavy rain, the rainwater grate adopts a double-grate form. On the one hand, the drainage outlet area of the road can be increased; on the other hand, if factory debris (such as plastic bags, etc.) blocks part of the rainwater grate during drainage, the effective use area of the rainwater grate can be guaranteed.
[0037] In the specific implementation, except for some areas that are prone to drainage ditch blockage, the drainage ditches of the whole plant are set as blind ditches, the drainage ditch covers are 200-300mm below the ground, and the green belts are covered with soil 7 and planted with green belts 6 to ensure the beauty of the whole plant. Figure 2 As shown, the rainwater grate 3 and the drainage ditch 2 are respectively arranged on both sides of the curb 8.
[0038] In the specific implementation, in order to ensure aesthetics and reasonably reduce the number of drainage ditches in the factory area, the factory roads can be set to single-sided slope, with rain gutters and drainage ditches only on one side of the factory roads. This can reduce initial investment, reduce drainage interfaces, and facilitate subsequent operation and maintenance. The single-sided slope of the factory road is set to 1.5%.
[0039] The arrangement of the drainage system in this embodiment has the following advantages:
[0040] Effectively reduce the number of drainage ditches in the plant area, making it easier for power station operators to conduct inspections and maintenance;
[0041] By setting up underground drainage, the aesthetics of the factory area can be ensured;
[0042] By increasing the area of the rain grate, effective drainage area can be guaranteed and kept unobstructed;
[0043] The rainwater grate can play a simple preliminary sedimentation role, ensuring that debris and heavy objects do not flow into the culvert and cause blockage.
[0044] In one or more embodiments, a power plant is provided based on the above-mentioned drainage system, including a cooling tower area, a transformer and GIS area, a steam turbine room, a boiler room and a desulfurization area, wherein each area is surrounded by a plant road and the above-mentioned culvert drainage system for the power plant area.
[0045] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations.
