Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.

Referring to fig. 1-4, a reinforced roadbed pavement structure for preventing ponding, 1, including roadbed body 1, set up water drainage canal 2 on the roadbed body 1, water drainage canal 2 adopts the design commonly used among the prior art for daily drainage and satisfy the drainage in difficult ponding highway section, and be provided with drainage assembly in the roadbed body 1. Wherein:

the drainage assembly comprises a drainage pipe 3, the drainage pipe 3 is arranged in a drainage canal 2, the upper end of the drainage pipe 3 is slidably connected with an extension pipe 4, the upper end of the extension pipe 4 is communicated with an elbow pipe 5, the lower end of the elbow pipe 5 is fixedly connected with a filter screen 6, two sides of the elbow pipe 5 are fixedly connected with a railing 7, the upper end of the railing 7 is fixedly connected with a floating block 8, a diversion trench is arranged on the inner wall of the drainage canal 2, which is close to the elbow pipe 5, the upper surface of the drainage canal 2, which is close to the railing 7, is fixedly connected with a limiting rod 9, the side wall of the limiting rod 9 is fixedly connected with a spherical bump 10, in the design, the drainage pipe 3 is matched with the elbow pipe 5, and is used for setting additional drainage configuration aiming at easily accumulated water road sections, which can not meet drainage requirements, on one hand, the additional drainage configuration is not started when the daily canal 2 meets requirements, and the additional drainage configuration is not blocked, on the other hand, when the water level in the drainage canal 2 is higher and additional drainage is needed, the water level in the drainage canal 2 rises and then enters the drainage pipe 3 through the bent pipe 5, and a siphon phenomenon is formed, so that water flows along the bent pipe 5 and then enters the drainage pipe 3, the water inlet is positioned below, when drainage is not needed, partial impurities blocking the filter screen 6 can be naturally separated from the filter screen 6 under the action of gravity, and due to the floating block 8, the bent pipe 5 can be driven by buoyancy to float when drainage is needed, so that the water inlet of the bent pipe 5 is not close to the water surface and the water bottom, is positioned in the middle position of the water level, is not easy to suck impurities floating on the water surface and is not dissolved in the impurities sucked into the water bottom, wherein the limiting rod 9 is matched with the spherical bump 10 to avoid the phenomenon that the bent pipe 5 floats too fast and cannot form the siphon phenomenon, for ensuring the drainage effect of the bent pipe 5.

Furthermore, the diversion trench comprises a sinking trench 11, a baffle 12 is arranged above the sinking trench 11, the sinking trench 11 is arc-shaped, the sinking trench 11 is fixedly connected with a current-limiting plate 13 near the inner wall of the filter screen 6, the baffle 12 is used for enlarging the water inlet area, and the current-limiting plate 13 is used for reducing the cross-sectional area through which water can circulate, so that the flow velocity is improved, and the showering effect to the filter screen 6 is promoted.

Furthermore, the upper end of the drainage canal 2 is covered with a cement board 14, and the cement board 14 is provided with strip-shaped holes, so that the drainage canal 2 can be used as a humanoid channel or can not prevent pedestrians from crossing a road while the cement board 14 is matched with the strip-shaped holes to ensure the drainage effect.

Furthermore, the floating block 8 is in a frustum shape, and the cross section of the upper end of the floating block 8 is larger than that of the lower end of the floating block 8, so that the buoyancy increasing speed of the floating block 8 is geometrically multiplied when the water level rises, and the elbow 5 can float upwards when the water level rises.

Furthermore, the stop lever 9 is made of elastic material, and the stop lever 9 is arranged against the railing 7, although the diversion trench is arranged to ensure that the calandria can realize the drainage effect, the arc-shaped pipe is easy to be blocked by stains on the bottom layer of the water flow under the condition that the arc-shaped pipe cannot float upwards, so the stop lever 9 made of elastic material is arranged to ensure that the bent pipe 5 can still move up and down under the drive of the floating block 8 even if the spherical protruding block 10 is hardened after long-term use.

Furthermore, the baffle 12 is trapezoidal, and the lower surface fixedly connected with extension board 15 of baffle 12, the baffle 12 is kept away from the one end fixedly connected with of drain pipe 3 and is inclined the block 16 that sets up, sets up the block 16 and is used for stopping daily drainage time, impurity in the aquatic, avoids appearing the guiding gutter and does not wash impurity on the filter screen 6, makes filter screen 6 by the condition of impurity jam on the contrary.

The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art, who is within the scope of the present utility model, should make equivalent substitutions or modifications according to the technical scheme of the present utility model and the inventive concept thereof, and should be covered by the scope of the present utility model.
