PERVIOUS CONCRETE PAVER SYSTEM AT ROAD JUNCTION IMPROVEMENT FOR SURFACE RUN-OFF WATER HARVESTING

Abstract

The present invention provides a novel pervious concrete paver system designed to address surface run-off water management and groundwater recharge, particularly at road junctions and other urban infrastructure areas. This innovative system incorporates pervious concrete pavers that allow rainwater and surface run-off to infiltrate through the pavement surface into a strategically designed sub-base layer. The sub-base layer, composed of graded aggregates, temporarily stores and facilitates the filtration of water before it reaches the underlying soil. A geotextile fabric positioned between the sub-base and soil prevents soil migration and enhances filtration. Additionally, the system includes optional water storage chambers and drainage outlets to manage excess water during heavy rainfall, directing it to appropriate storage or drainage areas. The pervious paver system reduces surface water accumulation, mitigating waterlogging and improving traffic safety. It also promotes groundwater recharge, contributing to sustainable urban water management and reducing the heat island effect. The system's modular design allows for adaptation to various urban settings, including parking lots, pedestrian pathways, and public squares, offering a versatile and environmentally-friendly solution for effective water management.

Specification

Description:2. Field of the invention
This invention relates to a novel pervious concrete paver system for improving road junctions and efficiently harvesting surface runoff water. The system is applicable in urban infrastructure, particularly in areas that face waterlogging and drainage issues due to heavy rainfall.
3. Background of Invention
• In urban areas, road junctions are hotspots for waterlogging due to the large volume of surface runoff during rainy seasons. Traditional road designs often fail to manage this runoff efficiently, leading to erosion, traffic congestion, and deterioration of road quality.
• The current technology focuses on pervious concrete pavers that allow water to percolate through, reducing surface runoff and promoting groundwater recharge, especially in areas where water harvesting is critical.
4. Objective of the Invention
• Primary Objective: To provide an efficient and sustainable road junction improvement solution that addresses surface runoff issues and facilitates water harvesting.
• Secondary Objective: To improve road durability and prevent waterlogging, while simultaneously reducing the risk of accidents caused by wet and slippery road conditions.
5. Advantages
• Water Harvesting: Allows rainwater to seep into the ground, thereby aiding in groundwater recharge.
• Reduction in Waterlogging: The pervious structure mitigates surface runoff, preventing water from accumulating on roads.
• Environmental Benefits: Reduces the need for additional stormwater drainage systems and promotes a greener infrastructure.
• Cost-Effective: Decreases the wear and tear on roads caused by water erosion, leading to reduced maintenance costs over time.
• Urban Cooling: The water permeating through the system contributes to the cooling of the surrounding environment, helping to mitigate the heat island effect in cities.
, Claims:• Claim 1: A pervious concrete paver system comprising a pervious surface, a sub-base for temporary water storage, a geotextile fabric layer, drainage outlets, and water collection chambers.
• Claim 2: The system of claim 1, wherein the pervious concrete pavers allow for a minimum water infiltration rate of X liters per minute per square meter.
• Claim 3: The system of claim 1, wherein the sub-base comprises layers of graded aggregates with a thickness ranging from Y to Z cm.
• Claim 4: The system of claim 1, further including a water storage chamber capable of storing up to X liters of water.
• Claim 5: A method for constructing a road junction improvement system as described in claim 1, involving excavation, sub-base preparation, laying of geotextile fabric, and placement of pervious concrete pavers.

Claim 6:The system of claim 1, further comprising a surface coating or treatment applied to the pervious concrete pavers to enhance their resistance to surface wear, staining, and clogging.
Claim 7:The system of claim 1, wherein the water storage chambers are modular and can be integrated into the system in various configurations, including cylindrical, rectangular, or cubic shapes, with storage capacities ranging from 500 liters to 10,000 liters, depending on the expected volume of runoff.
Claim 8:The system of claim 1, wherein the drainage outlets are equipped with adjustable valves or gates to control the flow of water and direct it to either the storage chambers or external drainage systems based on real-time water levels and flow conditions.
Claim 9:The system of claim 1, wherein the pervious concrete pavers are designed to withstand vehicular traffic loads with a compressive strength of at least 20 MPa to ensure durability and long-term performance.
Claim 10:The system of claim 1, wherein the pervious concrete pavers have an average water infiltration rate of at least 500 liters per square meter per hour to effectively manage and process surface runoff.
