A hollow roadside stone and casting mold with water collection, drainage and water seepage

Abstract

The invention discloses a hollow road edge stone suitable for collection of rainwater on the road surface of an urban road and having functions of a water draining pipeline and a mold for making the road edge stone. The hollow road edge stone is characterized in that the hollow road edge stone is in a shape of a hollow cuboid and is provided with a cavity with a quasi-rounded cross section in the length direction to serve as a main water draining flow channel of the road edge stone. A plurality of conical holes are formed in the left side and the right side of the main flow channel. The conical holes are communicated with the main flow channel, and the bigger ends of the conical holes are communicated with the main flow channel of the quasi-rounded cavity. The mold comprises a whole formed by a base plate, a left side plate and a right side plate, front and back end plates, a core rod and a rubber ring arranged on the periphery of the core rod in a sleeving mode. The hollow road edge stone can collect the rainwater on the road surface through the plurality of conical holes. Due to the fact that the smaller ends of the conical holes are communicated with the road surface, large tree leaves and other sundries are not easily flushed into the pipeline, the water flow resistance of the flow channel with the conical holes is also smaller compared with straight pipe water inlet holes same as the small ends of the conical holes in caliber, and blockage does not easily occur.

Description

technical field [0001] The invention relates to the production of concrete block products, in particular to a curb stone suitable for collecting road surface rainwater on urban roads and also having the function of a drainage pipe, and a mold for making the curb stone. Background technique [0002] Curb stones are mainly used on urban roads. Between the motorway and the sidewalk or green belt, a strip of concrete or natural stone blocks is installed along the longitudinal direction of the road to separate the motorway from the sidewalk or green belt. Becoming the boundary stone on the edge of the road surface, it can not only play the role of retaining water and soil, but also play the role of beautiful decoration on the road. Existing curbs are mainly solid concrete or solid blocks, which only have a single isolation function. In order to remove the accumulated water on the road, additional drainage pipes and ditches are required. In order to improve this situation, there...

Problems solved by technology

However, the above design also has the disadvantages that the interface construction is not convenient enough, and the water collection inlet is easy to be blocked.

Another problem with the current road drainage system is that the way of rainwater discharge is mainly to collect rainwater from the road surface to the drainage ditch, then collect the water from the drainage ditch to the branch drainage ditch, and discharge the main drainage ditch to the river or sewage treatment station, but the rainwater is discharged to the sidewalk or greenery. The soil below the belt has little infiltration, which is not conducive to ecological balance
