Description

A High-Intensity Pathway for Water Adaptation Systems in Response to Climate Change

technical field

The invention relates to a high-strength road for a water resource adjustment system in response to climate change, especially a system with a high-strength structural space constructed underground, and various types of road pavement or permeable pavement or pavements constructed above the structural space. Water-permeable materials are added to provide a high-strength and high-load road surface that can withstand the heavy pressure of vehicles.

Background technique

Due to the continuous progress and expansion of cities and the construction of various man-made facilities, the area of roads continues to increase, resulting in the gradual loss of the original water retention capacity of the catchment area, resulting in a substantial increase in surface runoff. Traditional roads cause a large amount of surface runoff due to imperviousness. One of the main causes of urban waterlogging, coupled with the impact of climate change caused by global warming, makes urban areas face greater pressure on flood control. In addition, traditional water control focuses on point and line water control, and various large and small reservoirs are built and drainage ditches and other facilities. In extreme weather, sudden heavy rainfall often comes. Traditional roads and drainage ditches cannot cope with heavy rainfall and cause urban waterlogging. Large areas often have stagnant water or even large areas of flooding due to poor drainage. Traditional water control standards and The standards and concepts of road construction can no longer meet the needs of climate change.

Ordinary traditional roads prevent the natural circulation of water and air between the ground and the ground, resulting in the formation of an "ecological desert" in the underground area of the road area that lacks water and oxygen; in order to cope with heavy vehicles, the roadbed must be compacted and drainage ditches must be installed , so the subgrade of the road cannot contain water and cannot store water. Therefore, whether the traditional road is a general road, a permeable paved road, or a high-load and high-flow road, the subgrade must be compacted, and the road bed must be closed to prevent rainwater from entering the road bed or subgrade. , so as to avoid causing the subgrade to soak in water, soften, collapse and sag, causing damage to public security personnel.

Therefore, the traditional permeable pavement needs to prevent rainwater from infiltrating the roadbed and subgrade. It cannot allow rainwater to infiltrate the subgrade. Therefore, drainage facilities must be installed to drain rainwater through drainage ditches. It is a pity that precious water resources cannot be retained. Therefore, designing a new form of road with water permeability and underground structures with high-strength water storage space can be used as a water conservation effect.

In terms of water permeability and underground water storage functions, traditional roads are neither fully permeable nor fully water-storage, and will cause a large amount of surface runoff, which is also the main cause of urban waterlogging.

In order to combat global warming and reduce the environmental load and its negative impact, the low-impact development technology promoted has been questioned for more than 20 years, and some parts have not been perfected, especially due to flooding or drought and high temperature caused by the earth. The effects of extreme climate warming are sometimes getting worse. The maintenance cost of the promoted low-impact development technology is very high. It is the best condition and incentive to consider providing a sustainable development, economic benefits, and convenient maintenance. The concept of sponge city construction is a kind of construction of flood prevention and Waterlogging and hopes to build a new type of city planning and construction with ecological and environmental protection functions; for example, building permeable pavement to replace non-permeable pavement, which can absorb, store and infiltrate water when it rains. In addition, underground water storage tanks will be installed in parks and squares respectively. Water storage, etc. When the climate is dry and hot, it can release water vapor to improve the heat island effect and prevent global warming. The construction methods and materials of the sponge city, the permeable function of the permeable bricks and the function of water storage are generally not able to withstand heavy pressure. It is not sustainable and stable and can adapt to earthquake shaking or heavy vehicle rolling damage on the ground. It can only be used on sidewalks, parks, and squares where non-heavy vehicles can reach, so as to prevent heavy vehicles from falling and causing public security concerns. On both sides of the road, drainage ditches still need to be set up to discharge the rainwater on the ground surface, so urban drainage ditches are easy to cause environmental pollution, and are easy to block, and are not easy to maintain and clean. Form a visual unsightly appearance.

For this reason, in order to match the construction of various permeable pavement facilities on the ground, in order to effectively store and reuse the rainwater introduced into the ground, a series connection between the ground and the ground is designed to be more resistant to heavy pressure, and can withstand tens of tons or more. The main motivation of the present invention is the high-load road repeatedly rolled by 100-ton vehicles, and the system formwork space where the above-ground and underground structural spaces are built together to create a water storage and drainage system.
