Silica Sand Honeycomb Structure Reservoir

Posted by

Silica Sand Honeycomb Structure Reservoir

(A) technical introduction and scope of application
Using desert silica sand as a raw material for the production of blocks, overlapping lamination to form hexagonal silica sand permeable wells, and then through the silica sand wells modular assembly to form a stable honeycomb structure, built in the ground to form a water storage space, from the inlet to the outlet Of each honeycomb wall to play the role of filtering rain; the reservoir will be permeable impermeable sand laying hexagonal honeycomb structure at the bottom of the water storage space, and in the upper part of the cover breathable impermeable brick to form a composite breathable impermeable layer, A waterproof, breathable double effect.
Scope: urban roads, squares, buildings and residential areas, green space, wetlands and other regions of the regulation and storage of rainwater.

(B) technical measures
1. Performance indicators
Silicone honeycomb structure of the reservoir water storage rate can be as high as 90%, the main indicators of water quality within the pool: water dissolved oxygen ≥ 8mg / L; COD ≤ 20mg / L; ammonia nitrogen ≤ 1mg / L
The silica sand honeycomb structure reservoir mainly consists of silica sand well block (Figure 1), breathable impermeable sand (Figure 2) and breathable impermeable brick (Figure 3).

2 technical characteristics
(1) The effluent quality of the siliceous honeycomb structure reservoir reaches Grade III water standard on the surface. ① Because the silica sand well block takes the filter material as the core, multiple filtration and purification are performed, and the water quality is good after the treatment; ② The silica sand well block is made up of honeycomb pores, which is highly efficient and permeable to water and forms the implantation vector of biological bacteria; It is characterized by creating a small environment for the survival and reproduction of biological bacteria and making full use of the harmful substances of large amount of breeding biological bacteria to decompose water body to effectively reduce the BOD and COD in the water body. 4) Supporting the development of permeable impermeable material pavement bottom, Environment, set up a breathable impermeable layer at the bottom instead of the usual geomembrane or seepage proof concrete impermeable, waterproof and breathable, is conducive to increasing water dissolved oxygen, so the water quality to maintain a long time, so that long-term preservation of water does not degenerate.
Silica sand honeycomb structure reservoir (shown in Figure 4) by the desert sand sediment made of permeable silica sand water blocks spliced ​​together to form an ultra-stable hexagonal honeycomb structure, reducing the consumption of resources such as clay and stone The use of materials to achieve the effective use of Aeolian sand, changing sand treasure. Rain-free parts and materials sintering-free shape, does not consume energy, the system requires only a set of water lifting facilities, running low energy consumption.
Silicone sand hive structural reservoir consists of hexagonal silica sand water well, water wells assembled ultra-stable honeycomb water storage space, the entire pool carrying capacity, safe and reliable parking. Structural replacement of the PE water storage tank invented abroad, not only stable and reliable structural stability, and the water storage rate can be as high as 90%.
