Abstract
The invention relates to an earthquake-resistance protecting pipe for a petroleum and natural gas pipeline, which consists of a reinforcement cage and a concrete pipe body, the reinforcement cage is coaxially embedded in the concrete pipe body, wherein the inner cross section of the concrete pipe body is quadrangle. The invention has the advantages of simple integral structure, scientific and reasonable design, high safety, strong seepage prevention performance, low cost and convenient installation, and can effectively reduce the damage to the petroleum and natural gas pipeline caused by earthquake.
Description
Technical field
The present invention relates to oil, natural gas line protecting tube field, especially a kind of oil, 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 object of the present invention is to provide a kind of oil, natural gas line earthquake-resistance protecting pipe, this protecting tube can effectively reduce the infringement that earthquake brings for oil and natural gas line, and is safe, and impervious strong, cost is lower, and is easy for installation.
The present invention solves its technical problem and is achieved through the following technical solutions:
A kind of oil, natural gas line earthquake-resistance protecting pipe are made of Framework Of Steel Reinforcement, concrete tube body, and Framework Of Steel Reinforcement is coaxial to be inlaid in the concrete tube body, it is characterized in that: the interior cross section of concrete tube body is a quadrilateral.
And described quadrilateral is a rectangle or square.
And, coaxial respectively bellmouth and the socket of installing in the two ends of described concrete tube body.
And, the coaxial respectively flange that installs in the two ends of described concrete tube body.
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.
Advantage of the present invention and beneficial effect are:
1. the interior cross section of the concrete tube body of this oil, natural gas line earthquake-resistance protecting pipe is a quadrilateral, and this quadrilateral can be rectangle or square, can effectively increase the area of operation in the protecting tube, helps maintenance, maintenance and convenient installation the in the pipeline.
2. the socket outer wall of this oil, natural gas line earthquake-resistance protecting pipe radially is shaped on 1-3 groove or boss; adopt the flexible interface structure; 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. coaxial setting-in Framework Of Steel Reinforcement in the concrete tube body of this oil, natural gas line earthquake-resistance protecting pipe, 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 lighter, the convenient installation reduced 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 oil, natural gas line earthquake-resistance protecting pipe can effectively be resisted the infringement that earthquake brings oil and natural gas line, even the present invention can not have influence on the inner oil and the Security of natural gas line because soil layer overstocks distortion yet.
5. overall structure of the present invention is simple, and design science is reasonable, and is safe, and impermeability is stronger, and cost is lower, and is easy for installation, can effectively reduce the infringement that earthquake brings for oil and natural gas line.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is that the A-A of Fig. 1 is to cross-sectional view;
Fig. 3 is that the B-B of Fig. 1 is to cross-sectional view.
Embodiment
The invention will be further described below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
This oil, the natural gas line earthquake-resistance protecting pipe, by Framework Of Steel Reinforcement 3, concrete tube body 5 constitutes, coaxial respectively bellmouth 6 and the socket 1 of installing at the two ends of concrete tube body, this bellmouth and socket are steel, the socket outer wall radially is shaped on 1-3 groove or boss, the present embodiment accompanying drawing is depicted as the socket outer wall and is shaped on 2 grooves 2, when socket is connected with bellmouth, in the socket groove corrosion-resistant O-ring seal can be installed, two ends at concrete tube body also can coaxially respectively install flange, be used to connect two protecting tubes, Framework Of Steel Reinforcement is inlaid in the concrete tube body, this Framework Of Steel Reinforcement can form for being installed by the vertical muscle of N root, and the span of N is 1≤N≤50, also can be for installed the cylindrical reinforcing bar cage that forms by circumferential reinforcement and longitudinal steel bar.Present embodiment adopts the Framework Of Steel Reinforcement form of having only vertical muscle, and the quantity N of vertical muscle is 8, coaxial uniform being packed in the concrete tube body, innovative point of the present invention is: the interior cross section of concrete tube body is a quadrilateral 4, this quadrilateral can be square or rectangle, and present embodiment quadrilateral shown in the drawings is square.
Quantity 2≤N≤50 of the vertical muscle in the concrete tube body of the present invention o'clock, can adopt the production method of common prestressed reinforced concrete pipe to realize, when the quantity N=1 of the vertical muscle in the concrete tube body, can add support at mould of the present invention, prop up socket or bellmouth, to reach the purpose of cast, other technology is with adopting common prestress steel sleeve concrete pipe production method.
