Description

TITLE: HIGH-STRENGTH ROAD FOR WAFER RESOURCE REGULATION
SYSTEM IN RESPONSE TO CLIMATE CHANGE
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a high-strength road for water resources regulation in response to climate change, and more particularly to a high-strength high-occupancy road, in which a structural space system having a high strength is constructed in an underground in combination with various types of road pavement or water-permeable pavement or additionally arranged water-permeable material constructed on a top of the structural space to also feature bearing of heavy loading of vehicles.
DESCRIPTION OF THE PRIOR ART
Due to increasing expansion of cities, with all sorts of man-made facility being massively built, road areas are continuously increased, resulting in catchment basins losing the functionality of water retention, leading to a great increase of runoff flows on the ground. Traditional roads are not water permeable and cause massive surface runoff flows. This is one of the major causes for flooding in the cities, and this, together with the impact caused by climate change resulting from global warming, forces all urban areas to encounter an increased strain for flooding prevention. In addition, the traditional ways of flood control often place emphasis on flood control of points and lines by building up various facilities of large- and small-sized dams and drainage ditches.
Extreme weather often causes sudden strong precipitation, and the traditional roads and drainage ditches are incapable of handling in-city flooding resulting

2 from the strong precipitation and large-area water accumulation or even large-area flooding may thus result due to poor drainage in the large area. The traditional flood control standard and the road construction standard and concept are far less than necessity for handling climate change.
The traditional roads isolate the natural circulation of water and air between the ground surface and the underground, making the underground of the road areas becoming an ecological dessert devoid of water and oxygen. The traditional roads place emphasis on traveling of heavy vehicles thereon and thus have to have a compacted road base and an arrangement of drainage ditch, resulting in a disadvantage that the road base is not allow to contain water and is not allowed to store water therein. Consequently, the traditional roads, either general roads or water-permeable pavement roads, or even high-occupancy high-flow public roads must have a compacted road base and have to have the road base or road bed enclosed to prevent rainwater from invading into the road bed or road base in order to avoid softening and collapsing of the road base due to soaking in water, which may result in casualty loss of public security persons.
As a result, the traditional water-permeable pavement road must prevent rainwater from penetrating into the road bed or road base, not allowing the rainwater to invade into the road bed. Thus, drainage facility must be built up to drain rainwater through the drainage ditches, and it becomes very pity for not keeping the water resources, which are precious. Thus, a novel road that features water permeability and constructs a high-strength water storage space building underground is proposed for an effect of water retention.

3 Concerning the water permeability function and the water storage function of the traditional roads, the traditional roads are incapable of full water permeability and are also incapable of full water storage, and may cause massive surface runoff flows, this being one major cause for in-city flooding.
To fight against the global warming in order to reduce the loading of the environment and the negative impacts caused thereby, low-impact development techniques have been made popularized, yet a concern about whether the popularization of the low-impact techniques over more than two decades is partly imperfect emerges, particularly flooding or drought, and influences resulting from extreme climate caused by global warming seemingly getting even worse sometimes. Maintenance costs for popularizing the low-impact techniques are very high, and in this concern, one that is sustainable, economic and easy to maintain is the best condition of perfection and attraction, and among others, a construction concept of a sponge city is a novel planned city construction in which functions of flood prevention and waterlogging prevention in combination with ecology and environmental protection is built in the city. For example, building a water-permeable road to replace a non-water-permeable road in order to absorb water, store water, and seeps water during raining, and also to set up water banks underground in parks and squares to store water therein. In drought and hot weather, water moisture can be released to alleviate the heat island effect and prevents situations of global warming. With respect to the making and materials of a sponge city, the water permeability function of water-permeable bricks and the water storage function of the water banks are generally incapable of carrying

4 heavy loads and cannot be sustainably secured and reliable to resist damages resulting from by for example shaking caused by earthquakes or pressurizing caused by heavy vehicle running on the road surface, and are only usable in building sites, such as sidewalks, parks, and squares, where the heavy vehicles are not allowed, in order to avoid public security concerns resulting from collapsing caused by pressurizing and running of heavy vehicles. And, there is still a need to build up drainage ditches at two sides of the road in order to drain off the rainwater falling on the ground surface. Thus, the urban drainage ditches may easily result in environmental pollution and may be easily jammed, and it is not easy to maintain and keep clean. The draining openings of the drainage ditches, once jammed by garbage, becomes visually unaesthetic for the outside appearance thereof.
In view of the above, in response to and collaborating with the construction of various water-permeable pavement on the ground surface, to effectively achieve effective storage and reuse of rainwater directed down into the underground, the present invention aims to provide a high-occupancy road that features interconnection between ground surface and underground and supportability of repeated running and pressurizing of heavy vehicles of tens of tons or hundred tons to achieve a system formwork space of a ground surface and underground co-constructed structural space to generate a water storage and water drainage system
