Technical Field

The invention relates to a composite material for a glass fiber reinforced plastic U-shaped water tank.

Background

In the traditional methods for agricultural irrigation water channels and urban drainage water channels, grouted rock blocks are generally used for building or in-situ concrete, cement mortar is used for plastering and press polishing to smooth the water surface of the water channel, and the construction is time-consuming and labor-consuming, low in work efficiency and not environment-friendly; the materials used consume natural materials (stone, sand); poor water tightness (concrete needs to be added with a permeation resistance agent); and the fracture is easy to generate and the maintenance is difficult to realize in the alpine region through the frost heaving; the friction coefficient (1.0) is high, the loss of the running water head is large, so that the cross section size of a water channel must be increased, the evaporation capacity of the running water of an open channel is large, the size and the weight of a cover plate of an underdrain channel must be increased, the cost is not saved, and meanwhile, the construction and the maintenance are difficult.

Furthermore, the concrete prefabricated U-shaped water tank is adopted, compared with the traditional method, the concrete prefabricated U-shaped water tank is processed in a factory and installed on site, the work efficiency can be improved conveniently in site construction, but the wall thickness is large in comparison, mortar is smeared on seams or tightness of seam twisting treatment cannot be guaranteed in construction, machinery and machines are needed for site installation when the water tank is heavy in self weight, the efficiency is low, the water tank is damaged, and the friction coefficient is still high due to the fact that a 'smooth cement surface';

furthermore, the plastic U-shaped water tank is manufactured by a manufacturer and installed on site by adopting a blow molding process, the manufacturing material can adopt a recycled product, the finished product has light dead weight, the tightness of a joint is easy to ensure by adopting a socket process, and the on-site construction is also convenient; the friction coefficient (0.6) is low, so that the section size can be effectively reduced; but the temperature stability is not good, the paint is not resistant to ultraviolet irradiation and easy to age, and the paint is easy to generate toxic gas to cause secondary pollution when being sunburned, and the paint can only be basically used for urban rainwater drainage side ditches; the blow molding process has poor rigidity and poor impact resistance.
