Guiding and draining side ditch made from building blocks and parameter determination method thereof

Abstract

The invention relates to guiding and draining side ditches made from building blocks. The guiding and draining side ditches are arranged on two sides of a road. Each guiding and draining side ditch atleast comprises a ditch bottom and ditch walls. The ditch bottom and the ditch walls form a side ditch with a cross section which is substantially trapezoidal. The ditch bottom forms a short edge, and the ditch walls form bevel edges of the side ditch. The side ditch is characterized in that each ditch wall comprises a ditch top and a side wall, wherein plants are planted in the ditch top facingthe side of the road and the ditch top far away from the side of the road in a staggered manner in a manner that the plants are irrigated conveniently. The ditch wall is formed by at least two types different building blocks. The two types of building blocks are capable of preventing a liquid from entering soil on a back side of the side ditch. The upper surfaces, protruding into the side ditch, of one type of building blocks are capable of absorbing and storing and keeping the liquid. The upper surfaces, protruding into the side ditch, of the other type of building blocks have structures thatdo not absorb the liquid but drain the liquid toward other building blocks on two sides, so that the ecological side ditch can adsorb harmful substances under a circumstance of leakage of the harmfulsubstances or can block and intercept the harmful substances when a lot of hazardous goods are leaked.

Description

technical field [0001] The invention relates to the technical field of drainage ditches, in particular to an ecological block guide drainage ditch and a parameter determination method thereof. Background technique [0002] Traditional masonry (trapezoidal or rectangular) side ditches have poor landscape performance and cannot be greened; at the same time, in order to manage dangerous goods transport vehicles and prevent leakage from polluting sensitive water bodies, multiple accidents are usually dug at both ends of bridges across sensitive water bodies. Emergency pools, these pools are difficult to construct and maintain, not only have poor landscape effects, but are often unable to 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 draining and guiding water, but also uses local grass species with developed root systems or grows close to the...

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
