Rainwater storage system
Rainwater storage system mainly refers to the collection of rainwater harvesting sites. First of all, should consider a certain area of the catchment area as a rainwater collection, there is no natural conditions of the place, you need to manually build rainwater collection. In order to improve the collection efficiency and reduce leakage loss, impervious material or impervious material should be used for anti-seepage surface treatment of rainwater collection surface.
Rainwater storage storage system construction method:
A. Compacted foundation;
B. Pouring cement cushion;
C. Pouring cement support column;
D. Laying geotextile and impermeable membrane;
E. Build plastic support module;
F. Build rainwater storage module;
G. Wrapped geotextile and impermeable membrane;
H. Backfill earthwork.
Rainwater storage use high impact modified polypropylene raw materials.
Compared with the prior art, the utility model has the advantages that:
1. The construction of brief introduction, can effectively shorten the life cycle.
2. Post-maintenance convenience. The plastic support module is located underneath the system, and is only cleaned periodically.
3. The system compressive ability. Rainwater storage capacity of the module itself with the pressure of the cement support column pressure, the positive pressure bearing capacity of more than 70 T.
4. The accumulation of rainwater storage height of up to 3 m or more. Cement support column in addition to the ability to pressure systems, but also improve the stability of the system can effectively prevent the rain water storage module side slip and other issues.
