Water blocking type kerb and construction method thereof

Abstract

The invention relates to the field of road infrastructures, and particularly discloses water blocking type kerb and a construction method for the kerb. The water blocking type kerb comprises cuboid stone and is characterized in that symmetric reverse rabbets are formed in the two ends of the cuboid stone, and two pieces of cuboid stone are connected and assembled; the reverse rabbets are connected to form a water blocking hole. The water blocking type kerb is simple in structure, reasonable in design, convenient to use, high in mounting speed, and suitable for high-position flower beds and slope greening in the sponge city construction, facilitates manual carrying, effectively improves the effect and saves the construction cost.

Description

(1) Technical field [0001] The invention relates to the field of road infrastructure, in particular to a water blocking curb and a construction method thereof. (2) Background technology [0002] Road drainage is closely related to everyone, and it is another distinctive feature of an international metropolis. Untimely drainage and incorrect selection of drainage methods will cause unnecessary trouble to the society and the people. Such as walking wet trouser legs, driving mud splashing and so on. [0003] The existing drainage method is to drain the accumulated water of road runoff along the curb from the road radially and collect it at the gully, and lead it into the sewer through the gully to achieve the purpose of drainage. The radial direction refers to the direction perpendicular to the length of the road. The existing drainage methods have at least the following defects: (1) In order to ensure the smoothness and strength of the road surface, viaducts, and elevated roads as m...

AI Technical Summary

Problems solved by technology

The existing drainage methods have at least the following defects: (1) In order to ensure the flatness and strength of the road surface, viaduct, and viaduct as much as possible, the number of gullies must be as small as possible, that is, the distance between adjacent gullies should be set relatively large, generally 30 -50 meters, therefore, in the process of collecting runoff from the bottom surface, the accumulated water on the road will collect fallen leaves, and the accumulated water on the road needs to flow a long distance along the length of the road surface to reach the rainwater outlet. During the flow process, the fallen leaves will accumulate more The more the fallen leaves are, the more the fallen leaves will overlap and increase. When they flow to the rainwater outlet, the accumulated large amount of fallen leaves will often paste the grate of the rainwater outlet, blocking or reducing drainage; (2) most of the current grates are made of metal. Once the grate is stolen, the exposed rainwater outlet is likely to cause traffic accidents; (3) In order to play a drainage role, the rainwater outlet is generally set lower than the road surface. When the vehicle passes through the rainwater that suddenly subsides When the gully is opened, it will inevitably generate a certain impulse. After a certain period of time, the impulse will inevitably cause damage to the road along the gully, which will easily cause damage to the road surface; (4) the size of the existing road gully is mostly 670×370mm, and the grate hole The interval is 2.6mm. When the road surface water reaches 10cm, the gully grate only collects water in the first two rows of grate holes, and the rest of the grate holes do not play any role.

[0004] In order to improve the above-mentioned traditional drainage methods, many cities in my country entered the national sponge city construction pilot scope in 2015, and infiltration facilities need to be built or rebuilt on sidewalks and green spaces. Many of the green flower beds outside the sidewalks and the high-level flower beds in building communities are higher than the ground or Terrain modeling has been carried out, and some slopes have been greened. If it is to be transformed into a sunken green space, the cost of reconstruction will be high, and the gain outweighs the gain
