Embodiment 1

[0038] Please refer to Figure 1 to Figure 8 , this embodiment provides an assembled bypass type drain tank for expressway pavement, including a drain tank body 2, and the two ends of the drain tank body 2 along the length direction are respectively a first connecting end 21 and a second connecting end 22, The two sides of the first connecting end 21 are symmetrically provided with inserting recesses 211 , and the surface of the second connecting end 22 is provided with inserting protrusions 221 matching the inserting recesses 211 . When in use, different bypass type drainage grooves can be spliced ​​and assembled through the cooperation of the insertion protrusion 221 and the insertion recess 211, so as to change the drainage direction, and the construction efficiency is high. The structure of the bypass drainage channel is simple, which can realize prefabricated production and on-site assembly, and can greatly improve the installation and construction efficiency of the drain...

Embodiment 2

[0050] Please refer to Figure 11 , the present embodiment provides another structure of assembled bypass type drain tank for expressway pavement. The difference from Embodiment 1 is that the number of through holes 24 on the drain tank body 2 is two, which are located in the drain tank respectively. The two ends of the main body 2 are symmetrically distributed to the center of the drain tank main body 2 . Compared with embodiment 1, since the number of through holes is less, the integrity of the drain tank body 2 is better, the strength is higher, the force is more uniform when pressed, and it is less likely to be crushed.

[0051] It should be noted that, in other embodiments, according to the actual needs of road conditions, the number of water diversion grooves 23 provided on the upper surface of the gutter body 2 can be reasonably selected, such as for a high-speed road with a long downhill section, the number of diversion grooves 23 can be appropriately increased. Numbe...

Abstract

The invention discloses an assembly type bypass form drainage groove for a highway road surface. The assembly type bypass form drainage groove comprises a drainage groove body, two ends of the drainage groove body are a first connection end and a second connection end correspondingly, insertion concave positions are arranged on two side faces of the first connection end correspondingly, insertionconvex blocks are arranged at the second connection end, the drainage groove body is provided with a T-shaped distributed drainage channel, wherein the drainage channel comprises a first flow guide channel and a second flow guide channel, and the upper surface of the drainage channel body is provided with an introduction notch communicating with the first flow guide channel. According to the assembly type bypass form drainage groove, splicing is achieved through matching of the insertion convex blocks and the insertion concave positions, the T-shaped distributed drainage channel formed by thefirst flow guide channel and the second flow guide channel is provided, the drainage direction can be changed after combining and splicing of the bypass form drainage groove, then road surface residual water can be quickly drained to drainage ports which are far away from each other on a road shoulder for drainage in time, the structure is simple, factory prefabricated production and manufacturingas well as site splicing can be realized, and the installation construction efficiency of the drainage groove can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of drain tanks, in particular to an assembled bypass drain tank for expressway pavement. Background technique [0002] High-grade highways usually use asphalt pavement structure. When it rains, rainwater will form residual water on the asphalt pavement. First, it is easy to damage the asphalt pavement. Second, it is easy to cause safety accidents such as skidding. At present, the conventional solution to the surface water on the expressway is to set the road surface to have a certain slope, and use this slight slope to guide the remaining water on the expressway laterally to the drain on the road shoulder for discharge. However, when the rainfall is heavy, for the high-speed road surface on the downhill section, because the rainwater is more likely to accumulate in the valley of the downhill road surface, simply relying on the conventionally set road surface with a slope to drain horizontally, the drainage w...
