As further improvement of the utility model, described baffler inner edge and skeleton outer rim are sealing setting.
As further improvement of the utility model, described overcoat is the PE overcoat.
As further improvement of the utility model, described reinforcement material is the tempered glass fibre reinforced plastics.
As further improvement of the utility model, described skeleton grooves inside arranges waterstop.
The utility model compared with prior art has following beneficial effect:
1. the utility model is simple and reasonable for structure, and practicality is high, applied range, and stability is high;
2. the utility model environmental protection, cost is low, water preventing ability good, defect rate is low, convenient for production.
