Filter Pavement – New Product

Sand based Filter Pavement

A new generation of permeable pavement

01 Product introduction

The sand-based permeable pavement is a new ecological and environmentally friendly pavement independently developed by Renchuang Technology, which enables rainwater to quickly penetrate into the surface, effectively replenish groundwater, alleviate the urban heat island effect, balance the urban ecosystem, and penetrate the earth’s atmosphere. “Let the ground warm in winter and cool in summer; water in the rainy season, snow in winter, absorb dust, reduce noise, increase the comfort of urban living; low cost of on-site paving process, short construction period, custom design, low after years of use The cost is quickly refurbished.

02 Features

Anti-clogging: Micron-sized pores are permeable to water by destroying the surface tension of water, and reduce water runoff;

Ultra-fast paving: Professional equipment can be laid thousands of square meters per day, no secondary reversal, construction waste is minimum;

Personalized customization: No need to open the mold, color customization, pattern paving, landscape integration, to achieve creative pavement;

Super cost-effective: The base layer is integrally formed, the surface layer is paved once, and at the end of the product life, it can be recycled.

03 Pavement structure

1—Sand-based permeable pavement surface layer; 2—permeable concrete cushion; 3—porous cement stabilized macadam base; 4-stage gravel base; 5-passage

Fully permeable structure

1—Sand-based permeable pavement surface layer; 2—permeable concrete cushion; 3—concrete base; 4—stabilized soil base; 5—subgrade

Semi-permeable structure

04 Technical indicators

05 Construction process

 

06 Pavement maintenance

     After the construction of the permeable concrete cushion is completed, the cover film is cured for 24 hours to ensure the bottom layer humidity.

     After the sand-based pavement of the permeable pavement surface is completed, it will be naturally maintained for 72 hours, and it is not allowed to step on or rain during the curing period.

     The permeable concrete surface shall not be pedestrian or open during maintenance.

     It is not allowed to be put into use until the floor has reached the design strength. The strength of the ground should be based on the strength of the sand-based permeable pavement surface test block and the permeable concrete test block.

The Rechsand Filter Pavement World Garden project was completed, demonstrating the wisdom of the sponge city construction

 
7 May 2019 Beijing China International Horticultural Exposition (hereinafter referred to as “World Expo”) will be held at Yanqing District of Beijing Rechsand Technology Group is the pioneer of the sand industry, the chairman unit of the Sponge City Construction Alliance, and the national rainwater utilization demonstration unit. This World Expo will use Rechsand sand-based Filter Pavers and Filter Pavements and other technical products to demonstrate its high-efficiency water filtering capability so that “water does not accumulate during small rain, does not flood during heavy rain, water does not turn black and odorous, and heat islands are alleviated”. The theme of the “Green Life, Beautiful Home” conference of the World Expo provides an effective solution.Construction Site

Sand-based Filter Paver

Rechsand Filter Paver is the core component of the rainwater expert system. It is a micro-scale pore permeable brick made from aeolian sand from the desert of Inner Mongolia through micro-particle full coating, interface modification, and sintering-free forming technology. The permeable performance of this permeable brick is more than 6 times that of ordinary ceramic or concrete permeable bricks.

Rechsand Filter Pavement

The existing sand-based Filter Pavement is a new ecological and environmentally-friendly pavement independently developed by Rechsand, which enables rainwater to quickly penetrate into the surface, effectively replenish groundwater, alleviate the urban heat island effect, balance the urban ecosystem, therefore breathable from under the ground. The ground is warm in winter and cool in summer; the rainy season is permeable, the winter snow is reduced, the dust is absorbed, the noise is reduced, and the comfort of urban living is increased; the overall cost of the paving process is low, the construction period is short, the pattern is customized, and sand material can be recycled at low cost after many years of usage.
