Description
Technical field
The utility model relates to oil, natural gas line protecting tube field, especially a kind of prestressed reinforcement framework plastic inner lining for petroleum, natural gas line earthquake-resistance protecting pipe.
Background technique
Oil, rock gas are the important non-renewable resources that are related to national economy, the pipeline that is used for transfer oil and rock gas at present mainly adopts steel pipe and alloy pipe, adopt between pipeline and the pipeline and be welded to connect, be outside equipped with anticorrosive coat in the pipeline, be used for resisting sulphide and other corrosive material of the high-load of oil.Oil; natural gas line when mounted; the general open channel excavation that adopts; buried after the pipeline welding in underground; or the excavation back adopts clay brick to be built into pipe trench; with oil; natural gas line is installed in the pipe trench; in use because the external environment condition complexity; often cause the pipeline oil impregnate; gas leakage; or even blast, and in recent years, along with the extruding each other of earth plate; earthquake is more and more frequent; especially on Sichuan and other places, because earthquake makes buried in underground oil; natural gas line has suffered crushing blow, so just seem even more important for the protection of oil and natural gas line.
Summary of the invention
The purpose of this utility model is to provide a kind of can effectively reduce the infringement that earthquake brings to oil and natural gas line, safe, impervious strong, cost is lower, prestressed reinforcement framework plastic inner lining for petroleum easy for installation, natural gas line earthquake-resistance protecting pipe.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of prestressed reinforcement framework plastic inner lining for petroleum; the natural gas line earthquake-resistance protecting pipe; by bellmouth; socket; Framework Of Steel Reinforcement; the concrete tube core; reinforcement wire; protective layer constitutes; install bellmouth and socket at the two ends of concrete tube core; at the coaxial Framework Of Steel Reinforcement that is embedded with of concrete pipe in-core; on the outer wall of concrete tube core, be fixed with protective layer; be wound with reinforcement wire on the outer wall of the concrete tube core in protective layer; it is characterized in that: the coaxial plastic inner lining that is fixed with of concrete pipe in-core wall, at the female end of concrete tube core and the plastic inner lining and the bellmouth of socket end; be fixed with the plastics shutoff between the socket diametrically respectively.
And described socket outer wall radially is shaped on 1-3 groove or boss.
And described Framework Of Steel Reinforcement forms for being installed by the vertical muscle of N root, and the span of N is 1≤N≤50.
And described Framework Of Steel Reinforcement is for to install the cylindrical reinforcing bar cage that forms by circumferential reinforcement and longitudinal steel bar.
And described protective layer is cement mortar protective course or concrete cover.
Advantage of the present utility model and beneficial effect are:
1. the concrete pipe in-core wall of this prestressed reinforcement framework plastic inner lining for petroleum, natural gas line earthquake-resistance protecting pipe is fixed with plastic inner lining, and its female end and interface end be coaxial respectively to be fixed with the plastics shutoff, make and keep airtight in the whole protection pipe, improved the impermeability of whole protection pipe, can make the good environment of the inner maintenance of protecting tube, improve the working life of oil and natural gas line, convenient maintenance.
2. the socket outer wall of this prestressed reinforcement framework plastic inner lining for petroleum, natural gas line earthquake-resistance protecting pipe radially is shaped on 1-3 groove or boss; by corrosion-resistant O-ring seal is installed the interface between two protecting tubes is sealed in each groove or in the space of boss composition; this cushion rubber is easy for installation; and the joint of bellmouth and socket can rotate to an angle; even when the whole generation of protecting tube sedimentation; also can effectively protect the Security of oil and natural gas line, prevent oil and natural gas line because extruding is blasted and wait danger.
3. the coaxial setting-in Framework Of Steel Reinforcement of the concrete pipe in-core of this prestressed reinforcement framework plastic inner lining for petroleum, natural gas line earthquake-resistance protecting pipe, and be wound with reinforcement wire at the outer wall of concrete tube core, can effectively improve the ability that pipeline integral body is resisted the external pressure load, resisting under the identical situation of external pressure load numerical value, its self weight of pipeline is the lightest, the convenient installation, reduce installation cost, and oil and natural gas line blast in time, also can effectively play protective action, reduce danger surrounding environment.
4. the flexible faucet structure of this prestressed reinforcement framework plastic inner lining for petroleum, natural gas line earthquake-resistance protecting pipe can effectively be resisted the infringement that earthquake brings oil and natural gas line, even the utility model is because soil layer overstocks distortion, after impact force disappears, can restore to the original state again, thereby can not have influence on the inner oil and the Security of natural gas line.
5. the utility model overall structure is simple, and design science is reasonable, and is safe, and impermeability is stronger, and cost is lower, easy for installation, can effectively reduce the infringement that earthquake brings for oil and natural gas line.
