Abstract
The utility model relates to a special pipe of a supply and drain pipeline. The utility model is characterized in that a fibre concrete special pipe is formed by high pressure air pressurizing mechanism with main raw material of concrete and fibre. The utility model has the advantages of high strength, good toughness, good shock resistance and high internal pressure strength; besides, two kinds of socket joint with different types which are respectively suitable for sealing by a sealing ring and cement; a fibre concrete high pressure special pipe can be used to match with an asbestos cement aqueduct and a reinforced concrete aqueduct used for water supply engineering; a fibre concrete low pressure special pipe can be used to match with a patented product which is a prestressed reinforced concrete downpipe used for sewerage engineering of buildings. The utility model has the advantages of low cost, non-perishable corrosion, non-perishable ageing, non-perishable deformation and long service life. The utility model is the most ideal replacing product of the existing cast-iron special pipes.
Description
The utility model belongs to a kind of section tube in aqueduct and the drainage pipeline, and fiber concrete high pressure shape tube is used for water delivery engineering; Fiber concrete low pressure special pipe is used for the sewer pipe of drainage system and building.
At present, in water supply and sewage work, concrete reinforced pipe and asbestos-cement pipe have been adopted widely.In the sewer pipe of building also progressively use patented product " prestressed reinforced concrete downpipe ", the patent No. 89212669.8.Owing to there is not the cement special piece supporting, in branching of pipes, positions such as turning have mostly adopted metal shaped tube spare and cement straight tube supporting.Metal shaped tube spare not only costs an arm and a leg, but also easy-to-rust has reduced service life.
The purpose of this utility model is to provide a kind of cheap, is difficult for the fiber concrete height of corrosion and aging distortion, the low pressure section tube.Thereby the substituted metal shape tube reaches to save iron and steel, economizes on the use of funds, and prolongs the purpose of using the longevity to make.
The technical solution of the utility model is: the shape tube tube wall adopts casting and compacting of concrete to form.In concrete, add an amount of fiber, improved the tensile strength of goods, improved its toughness and shock resistance.And to have designed be routine assembling die, adopted the advanced technologies of pressure-air extrusion forming, and it is complex-shaped to have solved the fiber concrete shape tube, and core is difficult for the difficulty of the demoulding.
Cross section of the present utility model is garden shape, and is provided with bell and spigot joint.According to the sealing means difference of joint, the utility model is provided with the bell and spigot joint (Fig. 1) that is suitable for the rubber seal sealing also the bell and spigot joint (Fig. 2) that is suitable for cement seal
Owing to adopted technique scheme, the interior pressure that the utility model ability is higher can satisfy the hydraulic pressure requirement of water engineering.(Fig. 2) be suitable for the bell and spigot joint of two kinds of different sealing modes owing to be provided with (Fig. 1), thus on-the-spot install very convenient flexibly.Owing to adopted the new technology of advanced pressure-air extrusion forming, so can produce the fiber concrete section tube of various model specifications.Can satisfy in the water supply and sewage work requirement of the heterotypic tube fitting of different shape.The utility model is aesthetic in appearance, the bright and clean height height of surfaces externally and internally, and it is strong to have a resistance to corrosion, long service life, advantage such as cheap.The ideal updated article of metal shaped tube spare really.
Description of drawings:
Accompanying drawing 1---Fig. 6 is a concrete structure schematic diagram of the present utility model.
Accompanying drawing has been described six embodiment of the present utility model.With reference to accompanying drawing (1) present embodiment be fiber concrete etc. through four-way, it is provided with the bell and spigot joint that is suitable for the rubber seal sealing.With reference to accompanying drawing (2) present embodiment be fiber concrete etc. through threeway, its connection-peg of depositing is suitable for mode with cement seal.Accompanying drawing 3---6 to be respectively fiber concrete be routine section tube structural representation.
Claims (1)
1, a kind of fiber concrete high and low pressure shape tube that is used for aqueduct and drainage pipeline is characterized in that the shape tube tube wall adopts casting and compacting of concrete to form, and has also added an amount of fiber in concrete.
