Abstract
The present invention relates to an irregular tube fitting in a group of drainage pipelines, which is characterized in that concrete and fiber are used as main raw materials, centrifugal, vibrating, extruding and other mechanical processing methods are utilized, a series of special moulds is designed, and a high pressure air pressurizing mechanism is used for making the fiber concrete irregular tube having high pressure and low pressure. The present invention has the characteristics high tensile strength, favorable toughness, good shock resistance, high leakage resistance performance, high degree of resisting internal pressure, etc. The present invention provided with a socket joint and a flange joint has convenient and flexible use and installation. The present invention having long service life which is longer than that of a cast-iron tube and low price which is less than 50 % of that of a cast-iron irregular tube is an ideal product for replacing the existing cast-iron irregular tube.
Description
The present invention relates to concrete prefabricated element in the fixed buildings, form for main raw material mechanism with cement and fiber, be used for the novel special pipe accessory of water supply and sewerage pipeline for a kind of.
In water supply and sewage work, adopted straight cement pipe at present widely, but at positions such as branch or turnings owing to there is not the cement special pipe of same material supporting with it, so mostly adopt the metal special pipe to match with the cement straight tube, yet the metal special pipe not only costs an arm and a leg, and easy-to-rust, thereby reduced working life.
The present invention's purpose is to provide a kind of cheap, fiber concrete high low pressure special pipe of being difficult for corrosion and aging distortion, and is supporting with the cement straight tube, be used for water supply and sewage work.
Technological scheme of the present invention is: the special pipe tube wall adopts casting and compacting of concrete to form, and has added an amount of Steel Fibre or polypropylene fiber in concrete, thereby has improved the tensile strength of goods, has improved the toughness and the impact property of goods.Designed special-purpose series of combination mould, adopted the advanced technologies of machining process such as centrifugal, vibrations, extruding and high-pressure air compression and moulding, it is complex-shaped to have solved fibre-concrete special pipe, the difficulty of core difficult drop-off.Produce complete in specifications, beautiful shape, any surface finish, cheap various fibre-concrete special pipe spares.
Owing to adopted technique scheme, the present invention that very high degree of compaction is arranged, higher voltage endurance capability and impermeability arranged, can satisfy the various hydraulic pressure requirements of water supply and sewage work, simultaneously, also have advantages of higher tensile strength and shock resistance, can satisfy the technological requirement in transportation, the installation.Fiber concrete low pressure special pipe has very strong impervious ability, detects through relevant department, and under the hydraulic pressure of 2 kg/cm, the pipe appearance does not have phenomenon of osmosis.When hydraulic pressure rose to 4 kg/cm, a little wet sheet only appearred in tube wall, but did not have globule trickling phenomenon.This index has surpassed the impervious standard of JC130-67 " Concrete and reinforced concrete drainage and sewer pipes " greatly.Fiber concrete high pressure special pipe can bear higher hydraulic pressure, and after tested, its working pressure has reached 10 kg/cm, has satisfied the hydraulic pressure requirement in the aqueduct.
Beautiful shape of the present invention, inner and outer surface degree of finish all is higher than the cast iron special pipe; Anti-corrosion capacity is better than cast iron tube; Be longer than cast iron tube working life and price is lower than cast iron tube.
