Description
Technical field
The utility model relates to reinforced concrete pipiline technical field, especially relates to the compound Pressure pipe of a kind of prestressing force steel reinforced concrete.
Background technique
In recent years, the development & construction of remote, large flow diversion works, heavy caliber conduit pipe material use quantity constantly increases.But usually lower defeated drainage pipe embedding manner all adopts the large excavator fluting that breaks ground, and after pipeline installation, carries out earthing landfill method of construction.And prestressed pipe is applied to waterline when construction of high workload pressure state, as run into the complicated location that city road, high building, railway, highway, river etc. have obstacle, be not suitable for ground channel excavation, as adopt channel excavation, must make construction section tear room open, stop, dam, to people's life, bring very big inconvenience, bring great economic loss simultaneously.So nowadays a lot of Corporation R & D prestressing force push pipes, adopt non-digging mode, utilize hydraulic jack machinery jacking construction technique, pipe installation, all in underground construction operation, does not damage above ground structure, safe and reliable, avoids adverse consequences.
Publication number is the patent " sedimentation-prevention type prestressing force push pipe " of CN 102537515 A, its bellmouth and socket are packed in respectively concrete tube core two ends, steel cylinder is inlaid in concrete pipe in-core and two ends are packed in respectively on bellmouth and socket, and in concrete tube core bottom, one is made a pipe base.The disadvantage one of its existence is that the exsertion part at joint socket steel loop does not carry out preservative treatment, affects sealing and the durability of push pipe; The 2nd, because increased Guan Ji, so increased considerably the resistance of jacking construction, increased the difficulty of jacking construction.Notification number is the patent " pre-stressed steel pipe " of CN 101498384 B, although its tube wall is thinner, steel using amount is less, cost is lower, but the disadvantage of its existence is the intensity that longitudinally only depends on pre-stressed steel pipe, thus in jacking construction as harder stratum, jacking construction difficulty is large, " pre-stressed steel pipe " is out of shape possibly, so it can not adopt non-digging mode to lay as push pipe.In prior art, also lacking can delivery high-pressure fluid, concrete reinforced pipe or the cylinder concrete pipe that can adopt non-digging mode to lay as push pipe again.In addition, also have the steel wire cover of general pressure tubing all to adopt outside to spray mortar cover, but because mortar cover surface is crude rough, while giving pipeline jacking, increased the resistance contacting with soil.
Summary of the invention
The purpose of this utility model is to provide a kind of prestressing force steel reinforced concrete compound Pressure pipe, and it can delivery high-pressure fluid, can adopt non-digging mode to lay as push pipe again; And antiseptic property is good.
Above-mentioned goal of the invention is achieved through the following technical solutions, the compound Pressure pipe of a kind of prestressing force steel reinforced concrete, comprise steel cylinder concrete circular die, ring orientation prestress steel wire, steel cylinder concrete circular die comprises bellmouth steel loop, socket steel ring, steel cylinder, longitudinal common nonprestressed reinforcement, tube core concrete; Described bellmouth steel loop, socket steel ring and steel cylinder are integrated by being welded to connect, its main points are, described steel cylinder concrete circular die outside also disposes longitudinal common nonprestressed reinforcement, and by watering and smash for the second time, with adhesion type pneumatic vibrator vibratory compaction, adopt steam High Temperature Curing, be combined with longitudinal common nonprestressed reinforcement and form concrete layer outside tube core, outside tube core, concrete layer has not only increased the intensity of steel cylinder concrete circular die, is again the protective layer of ring orientation prestress steel wire simultaneously; Described bellmouth steel loop is processed with outer end and outwards sticks up inner inside and outside chamfering of inwardly sticking up; On described socket steel ring, be shaped with double flute, double flute is embedded with seal ring.
As being preferable over, described bellmouth steel loop and the exposed parts of socket steel ring are shaped with anticorrosive coat.
As being preferable over, described anticorrosive coat is epoxy zinc-rich enamelled coating or epoxide coal bituminous enamelled coating.
The utility model compared with prior art, described steel cylinder concrete circular die outside also disposes longitudinal common nonprestressed reinforcement, and by watering and smash for the second time, with adhesion type pneumatic vibrator vibratory compaction, adopt steam High Temperature Curing, be combined formation with longitudinal common nonprestressed reinforcement, concrete layer outside tube core, outside tube core, concrete layer has not only increased the intensity of steel cylinder concrete circular die, be again the protective layer of ring orientation prestress steel wire, and outer wall is smooth simultaneously; Its state working pressure reaches 0.4～1.0MPa, and cracking resistance pressure reaches 2.1 MPa because above-mentioned reason it can delivery high-pressure fluid, can adopt non-digging mode to lay as push pipe again; Again because the first annulus of described bellmouth steel loop is processed into inside and outside chamfering with forming machine, the second annulus of described socket steel ring is with the two cushion rubbers of double flute, and outer wall is smooth, so resistance is little when apical grafting is managed in front and back, apical grafting is sealing, impervious good between rear tube and tube well; The exposed parts of bellmouth steel loop and socket steel ring is shaped with anticorrosive coat, so the antiseptic property of bellmouth steel loop and socket steel ring is good.
