An ecological block guide drainage ditch and its parameter determination method

Abstract

The invention relates to an ecological block guide drainage ditch, which is arranged on both sides of the road, and at least includes a ditch bottom and a ditch wall, and the ditch bottom and ditch wall form a side ditch with a roughly trapezoidal cross section, wherein the ditch bottom Constitute the short side, and the ditch wall constitutes the hypotenuse of the side ditch, and it is characterized in that the ditch wall includes a ditch top and a side wall, and the ditch top on the side facing the road and the ditch top on the side away from the road are in a way to facilitate plant watering The plants are staggered, and the ditch wall is composed of at least two different blocks, both of which have the ability to prevent liquid from entering the soil on the back side of the side ditch. The upper surface protruding in the ditch has the ability to absorb and retain liquid; the upper surface of the other block protruding into the ditch has a structure that does not absorb liquid but drains liquid to other blocks on both sides, so that the ecological edge The ditch can absorb harmful substances in the case of leakage of harmful substances on the road, or block and intercept harmful substances in the event of a large amount of dangerous substance leakage.

Description

technical field [0001] The invention relates to the technical field of drainage side ditch, in particular to an ecological block drainage side ditch and a method for determining parameters thereof. Background technique [0002] The traditional masonry (trapezoidal or rectangular) side ditch has poor landscape performance and cannot be greened; at the same time, in order to manage dangerous goods transportation vehicles and prevent leakage and pollution of sensitive water bodies, it is generally done by digging at both ends of bridges that cross sensitive water bodies. Emergency pools, these pools are difficult to construct and maintain, not only have poor landscape effects, but also cannot be deployed due to terrain restrictions. [0003] Although the traditional turf ecological side ditch has good landscape performance and can be greened, it not only has the function of water drainage, but also uses local grass species with developed roots or close to the ground, and has go...

Problems solved by technology

[0010] Chinese patent CN207062686U discloses a prefabricated assembled concrete shallow dish type side ditch, which solves the problem that blockages are easily embedded in the corners of the side ditch body in the prior art

[0011] None of the existing patents are designed to store, channel and purify road surface runoff beyond the edge of the gutter, especially when dangerous goods are dumped and leaked on the road surface, they do not have the emergency prevention function for dangerous goods leakage, and cannot be used in the case of harmful substances leakage. Adsorb harmful substances, or block and intercept harmful substances in the event of a large amount of dangerous material leakage
