Abstract

<P>PROBLEM TO BE SOLVED: To avoid disturbance in traffic on roads due to rainwater stagnating there and troubles due to rainwater scattered by running cars when rain falls on the surface of a road pave with asphalt or the like. <P>SOLUTION: A rainwater collecting/draining molding 7 made of three-dimensional synthetic resin nets having a thickness of 5 mm to 60 mm and a width of 10 mm to 100 mm is mounted on cut grooves of road surfaces at an appropriate interval to collect and drain stagnating rainwater. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

Technology field

  The present invention relates to a drainage and drainage material that excludes traffic obstruction due to poor drainage due to unevenness of the surface of the road surface, and scattered water obstruction due to running of a vehicle, etc., under conditions such as stagnant water due to rainfall on a paved road surface such as asphalt.

  In order to eliminate traffic obstacles due to water jamming when the road surface rains, the road surface on which permeable pavement that mixes and dissolves single-grained crushed stone and asphalt and pave the entire road surface is increasing. This permeable pavement effectively drains rainwater without stagnation during rainfall. However, compared to ordinary pavement, the cost is high and the entire road surface is peeled off, so if it becomes clogged with sediment particles after several years, such as road closure, construction time, etc., re-construction or high pressure water washing and vacuum suction etc. There was a problem.

Problems to be solved by the invention and the means thereof

It is possible to easily remove the obstacles caused by water jamming during rainfall, and to remove the water on the road surface without any traffic obstacles by removing it easily when it is clogged with sediment particles after construction and re-installing it. It is in the provision of collectable drainage materials.
A large number of wire rods that have been melted and extruded from a nozzle after being melted with a synthetic resin are collected and welded while they are not solidified. It is a drainage material that is attached to a groove cut by the like and drains water from the road surface by connecting it to a catchment.
In the new pavement construction, joint material having the same dimensions as the drainage material of the present application is simultaneously applied during pavement, and then the joint material is removed and the drainage material of the present application is mounted in the groove.
In order to solve the problem that the drainage material of this application is rigid and cannot be bent along the road surface during construction, the road surface where automobiles pass is necessary to withstand tire pressure etc. In addition to being able to cope with the shape and the bending, it is possible to attach an abrasion resistant material to the upper part.
It can also be constructed on paved roads where cars do not pass, and drainage of storm water can be done quickly.
When clogged after several years, if the drainage material of the present application is removed from the mounting groove, the clogged earth and sand are removed, and the reattachment is completed.

Claims (2)

  The synthetic resin is melted and extruded from a nozzle, and is pulled into a rectangular shape having a length of 5 to 60 mm and a length of 10 to 100 mm by gathering and laminating molten wire rods by taking it slower than the extrusion speed while it is not yet solidified. A drainage material that drains and drains rainwater by attaching a molded three-dimensional mesh-type drainage material made of synthetic resin to a pavement groove and connecting it to a side ditch, drainage basin, etc.   A bellows-like cut is provided so as to be bent with a cut groove at the bottom of the manufacturing process according to claim 1.
