Abstract
A kind of Prestressed concrete cylinder pipe and matched sealing ring, wherein Prestressed concrete cylinder pipe includes concrete tube core, stress wire, steel cylinder and interior layer concrete, the both ends of the concrete tube core have been symmetrically arranged annular slot, the annular slot is arranged concentrically with concrete tube core, and the sealing ring includes and the annular slot rubber outer ring to match and the steel ring being wrapped in rubber outer ring.The utility model realizes the docking of two Prestressed concrete cylinder pipes using the splicing in slot and sealing bosom, installation is more convenient, since sealing ring is integrally embedded in pipe of concrete in-core, without worrying corrosion of the extraneous corrosive medium to sealing ring, quality is more stable, and safety coefficient is higher.
Description
Technical field
The utility model relates to equipment for liquid transportation fields, and in particular to a kind of Prestressed concrete cylinder pipe and and its
Matched sealing ring.
Background technique
Currently, Prestressed concrete cylinder pipe (abbreviation PCCP), is a kind of novel rigid pressure tubing.It is with steel
The strong concrete tube core of cylinder winds compressor wire, spray with cement mortar protective course, using steel bell and spigot steel loop and with
Steel cylinder is welded into one, and the fluted sealing rubber ring of bell and spigot band forms the flexible joint of slidingtype cushion rubber, be steel plate, concrete,
The composite construction of high tensile steel wire and cement mortar different materials composition, has steel and the respective characteristic of concrete.Prestress steel
Cylinder pipe of concrete has bear in external pressure is high, joint tighness is good, shock resistance is strong, applies that convenient and efficient, antiseptic property is good, ties up
Shield such as facilitates at the characteristics, of interest by engineering circles, be mainly used in long distance water transfer main line, pressure inverted-siphon, urban water supply engineering,
Pressure water conveyer pipeline, electric power plant circulating water engineering pipeline, pressure blowdown main pipe etc..Compared with previous tubing, have it is applied widely,
The advantages that economic life is long, anti-seismic performance is good, easy for installation, operation expenditure is low, substantially water-tight.
Since bell and spigot steel loop with steel cylinder is welded together by two independent individuals, Prestressed concrete cylinder pipe
Bell and spigot steel loop directly it is exposed outside, the not protection of concrete layer, the connection as two Prestressed concrete cylinder pipes
Place, the surface protection of the socket steel ring of the bellmouth steel loop and Prestressed concrete cylinder pipe of Prestressed concrete cylinder pipe are especially heavy
It wants, the operational reliability of this direct threat tube system, pre- to influence the safe operation of entire pipe-line system, and now answers
Power cylinder concrete pipe does not do any safeguard measure substantially in this respect, finds in use, bellmouth steel loop and socket steel ring
It is easy to the failure that can be corroded, perforation leakage even booster phenomenon occurs, causes a hidden trouble to the safe operation of pipe-line system, directly
The operational reliability of threat tube system.
Summary of the invention
The shortcomings that the purpose of the utility model is to overcome the prior arts and deficiency, provide a kind of structure it is simple, it is easy for installation,
The stable Prestressed concrete cylinder pipe of quality and matched sealing ring.
In order to achieve the above object, the technical solution of the utility model is: a kind of Prestressed concrete cylinder pipe, including
Concrete tube core, the stress wire for being wrapped in concrete tube core outer rim, the pipe of concrete in-core wall are provided with steel cylinder, the steel
Cylinder inner wall is provided with interior layer concrete, it is characterised in that: and the both ends of the concrete tube core have been symmetrically arranged annular slot,
The annular slot is arranged concentrically with concrete tube core.
Matcoveredn is arranged in the stress wire outer rim.
A kind of sealing ring to match with Prestressed concrete cylinder pipe, it is characterised in that: including with annular slot phase
The rubber outer ring matched and the steel ring being wrapped in rubber outer ring.
Rubber raised line is provided with inside and outside rubber outer ring.
The thickness of the steel ring is not less than 10 millimeters.
Compared with prior art, the utility model has the following beneficial effects:
1, the utility model realizes the docking of two Prestressed concrete cylinder pipes using the splicing in slot and sealing bosom,
Installation is more convenient, since sealing ring is integrally embedded in pipe of concrete in-core, without worrying extraneous corrosive medium to sealing ring
Corrosion, quality is more stable, and safety coefficient is higher.
2, the steel loop in the sealing ring of the utility model can provide support for pipe of concrete, and the rubber ring of outer layer can mention
The serious forgiveness of the ductility of highly dense seal ring, the sealing ring of this structure is very high, even if geological disaster, which occurs, leads to pipe of concrete institute
It changes, the operation of pipe of concrete will not be influenced too much in landform, run more reliable.
3, the utility model is respectively provided with rubber raised line inside and outside the rubber outer ring, and such setting is so that sealing
Ring can be fitted tightly on the inner surface of slot during installation, and quality is more reliable.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of Prestressed concrete cylinder pipe in the utility model.
Fig. 2 is the structural schematic diagram of sealing ring in the utility model.
Fig. 3 is the internal structure chart of sealing ring in the utility model.
In figure: concrete tube core 1, stress wire 2, steel cylinder 3, interior layer concrete 4, annular slot 5, protective layer 6, outside rubber
Ring 7, steel ring 8, rubber raised line 9.
Specific embodiment
The utility model is described in further detail below in conjunction with Detailed description of the invention and specific embodiment.
Referring to Fig. 1, a kind of Prestressed concrete cylinder pipe, including concrete tube core 1, it is wrapped in 1 outer rim of concrete tube core
Stress wire 2, matcoveredn 6 is arranged in 2 outer rim of stress wire, and the pipe of concrete in-core wall is provided with steel cylinder 3, described
3 inner wall of steel cylinder is provided with interior layer concrete 4, and the both ends of the concrete tube core 1 have been symmetrically arranged annular slot 5, described
Annular slot 5 is arranged concentrically with concrete tube core 1.
A kind of sealing ring to match with Prestressed concrete cylinder pipe, structure-Fig. 3 referring to fig. 2, including inserted with annular
The rubber outer ring 7 that slot 5 matches and the steel ring 8 being wrapped in rubber outer ring 7, are made by use for large size hydraulic machine high temperature,
Steel ring 8 in sealing ring requires to be not less than 10 millimeters of steel plate with thickness according to pipe external and internal pressure, the rubber outer ring 7
Inside and outside be provided with rubber raised line 9.
In order to ensure the Prestressed concrete cylinder pipe pressure that sealing ring is born at work is more balanced, the annular slot
5 depth is seal ring width 1/2.
It is then pre- at two as long as the utility model gets out the sealing ring of suitable thickness according to field condition in a pre-installation
When stress cylinder concrete pipe docks, sealing ring is inserted into respectively in the annular slot 5 of two Prestressed concrete cylinder pipes, by
In 1/2 that the depth of annular slot 5 is sealing ring width, so after the installation is completed, sealing ring can entirely be embedded in pipe of concrete
In core 1, and watertightness performance accesses good guarantee.
