CN2488997Y - Composite pipe for water supply and drain - Google Patents

Abstract

The utility model discloses a composite pipe for water supply and drain. The utility model has high strength resisting both internal pressure and outer pressure, strong anti-leakage capacity, excellent corrosion resistance, no pollution to water, antifreeze and heat preservation functions, excellent electrical insulating property, small resistance factor and a long service life. The utility model is provided with a structure layer of a concrete pipe or a concrete reinforced pipe. The nozzle and the inside wall of the structure layer are provided with an inside lining of glass fibre reinforced plastic with a certain thickness. The structure layer which is made of concrete pipe or concrete reinforced pipe and the inside lining which is made of glass fibre reinforced plastic jointly compound to form an integrated composite pipe for water supplying and draining.

Description

A kind ofly compoundly give, gutter

The utility model relates to, drainage system, particularly a kind ofly compoundly gives, gutter.

Existingly give, gutter, of a great variety, wherein traditional concrete or reinforced concrete structure based on gutter, press load intensity not high in this gutter is anti-, impermeabilisation is indifferent, and the resistant rotproofness is poor, abrasion resistance and not high, because inner wall coarse causes the internal resistance coefficient big, thereby influences application life, no heat insulation effect, freeze proof, and glass fiber reinforced plastic is subjected to that outer to load with lotus intensity not high, shortcoming such as do not involve great expense.

The purpose of this utility model provide a kind of anti-inside and outside pressure load intensity height, wear-resisting, water imbibition is little, the anti-leakage ability strong, good corrosion resistance, to water nonpollution, have freeze proof heat insulation function, electrical insulating property is good, resistance coefficient is little, long service life compound given, gutter.

The technical solution of the utility model is: with concrete or concrete reinforced pipe is deck, applying certain thickness glass fiber reinforced plastic at the deck mouth of pipe and inwall is liner, and concrete or reinforced concrete structure layer and frp lining are combined into the giving an of integral body, gutter jointly.

The utility model is owing to be to be deck with concrete or steel concrete, kept its anti-outer load intensity height, characteristics that cost is low of pressing of carrying.The liner of glass fiber reinforced plastic makes pipe have anti-preferably interior load intensity, difficult infiltration, the corrosion resistant characteristics of pressing, and we can say that this pipe combines both advantages, has avoided their shortcoming.Compoundly give, gutter has following characteristics: anti-inside and outside pressure load intensity height is applicable to the different pressures pipeline; Anti-leakage power is strong, can well protect environment; Good corrosion resistance can be carried various media; The water quality of output is good, the no dirt of long-term use; Inner wall smooth, waterpower mill resistance coefficient is little, has long-time stability; Anti-freezing property and excellent thermal insulation performance; Has electric insulation functions; Long service life.

Below in conjunction with accompanying drawing, enumerate embodiment of the present utility model.

Fig. 1 is a structural representation of the present utility model.

Be deck 1 with concrete or concrete reinforced pipe, applying certain thickness glass fiber reinforced plastic 2 at the mouth of pipe of deck 1 and inwall and be liner, be combined into the giving an of integral body, gutter jointly by concrete or reinforced concrete structure layer 1 and glass fiber reinforced plastic 2 liners.

Claims (1)

1. One kind with concrete or steel concrete give, gutter is deck compoundly gives, gutter, it is characterized in that: applying certain thickness glass fiber reinforced plastic (2) at the mouth of pipe of deck (1) and inwall is liner.
