Description

Pressure fluid circulation duct and manufacture method thereof

The present invention relates to the fluid flow pipeline that under roadbed, to bury underground, especially relate to and be used for the circulation duct that pressure is approximately the high-pressure fluid of several crust.

The invention particularly relates to and have very big cross-sectional area for example greater than 2m ²Pipeline configuration, but also can perform well in the pipeline configuration of common size.

The invention still further relates to the method for this pipeline of structure.

Form and butt joint that fluid-transporting tubing can be made metal or concrete pipe unit simply connect, and the termination of these pipe units embeds each other by inserting joint.When sagging, some unit may fluff, thereby bears higher pressure.For example, for the pressurized delivered pipeline in power station, preferably adopt the metal tube unit that welds in its adjacent termination.

At this moment, this pipeline is made of prefabricated piping unit or curved wallboard, is transported to on-the-spot them and welding on the spot.But, this moment, this pipe was not under the pressure state, therefore can be out of shape and ovalisation, and this makes that welding is more difficult, because sheet material will no longer align.

And for example when as petroleum pipeline or gas pipe, this pipe is buried usually.When this pipe was in pressure state, it was easy to support the external loading that is applied by roadbed.But this pressure changes, even may become negative pressure with respect to the outside.At this moment this pipe has very big distortion danger.

Therefore, the sectional area of the pipe that forms by the weld metal tube elements is relatively limited, usually less than 2m ²

The inventor studied by the several years, had invented a kind of manufacture method of the pipeline that is used for the pressure fluid conveying newly, and this method does not have above-mentioned shortcoming.

In the method, pipeline is made of the sealing light-wall pipe that is fixed on the non-yielding prop body, and this light-wall pipe is generally metal tube, and this non-yielding prop body is made by the concrete of steel concrete or preload usually.Like this, this metal tube system that makes can seal and bear internal pressure, and thin-walled only bears tensile stress, and this concrete bodies makes pipeline have rigidity, it is bearing in by wideer surface and lays on the surface simultaneously, and this makes the load that applies disperse, and can bear local sinking better.

In document EP 0767881 disclosed method, the concrete bearing body preferably is made up of three parts, is respectively two lateral-supporting parts that are bearing in ground horizontal base and form vertical leg along each side of pipe.Therefore, this assembly becomes the U-shaped shape of the whole bottom of surrounding tube.Like this, described pipe is made of four plates on cross section, be respectively one at the base plate on the pedestal, two side plates on the dual-side leg and dual-side and the tangent top board that is connected of the respective end of biside plate respectively.Described side plate is by two leg supports of supporting mass, so their relative side can locate well, so that welding.

Such pipeline is easy to be made by prefabricated component, and the length of this prefabricated component can adapt with the ability of transportation and carrying.

The inventor makes further research, so that simplify the manufacture method of this pipeline, especially makes the lighter and easier installation of each prefabricated component, can also make it keep the various advantages that prior art had simultaneously.

Therefore, the present invention relates generally to the fluid flow pipeline, this pipeline comprises the sealed tube that is installed on the non-yielding prop body, this non-yielding prop body forms one and is bearing in the lip-deep pedestal of laying, described pipe has longitudinal axis, and is made of thin barrier, and this thin barrier closed in itself is to form the tubular shell of sealing, this tubular shell comprises the upper and lower, and this bottom will be contained on the inner surface of described supporting mass.

According to the present invention, this supporting mass comprises a single-piece part in the housing both sides, this single-piece part becomes L shaped on cross section, comprise a vertical substantially branch and the branch of a basic horizontal, this vertical branch forms the side direction wing plate of supporting mass, this side direction wing plate extends along the respective side of pipe bottom, the extension below the described bottom of pipe of this horizontal branch, and form at least a portion that places the lip-deep supporting mass pedestal of laying.

Particularly preferably be, on a certain segment length of pipe, the wing plates on two sides of supporting mass and pedestal form the single-piece of a U-shaped at least.

According to another embodiment of the present invention, on a certain segment length of pipe, this supporting mass comprises the part of two L shaped profiles at least, and the horizontal branch of two parts links to each other at the place, both sides of the pipe mid-plane of passing through longitudinal axis, so that form continuous pedestal.

Usually, supporting mass is made by steel concrete, and can strengthen by conventional method, and with the load that supporting applies, especially supporting will be to the load of lateral parts spread out.But, according to another preferred feature of the present invention, this reinforcement can be made by at least one curved sheets, this curved sheets inserts in the concrete bearing body, and two branches are arranged, be respectively level with vertical, this two branch all extends in the respective branch of each L shaped part of supporting mass.

Preferably, for the continuity that proof load is propagated, the L shaped side direction of each of supporting mass partly comprises an inner surface, so that lay and install housing, the direction of this inner surface gradually changes between the bottom of basic horizontal and vertical substantially top.

Other preferred feature is the theme of dependent claims.

By following explanation to specific embodiment, the present invention may be better understood, and this specific embodiment is the purpose that is used to explain, and showed by accompanying drawing.

Figure 8 shows that another embodiment that has interconnected crossbeam.

Fig. 9 and 10 expressions can change the embodiment of conduit axis direction.

Fig. 1 is the perspective diagram of the part of pipeline of the present invention, and this pipeline generally includes the pipe A that links to each other with concrete bearing body B.This pipe A comprises the curved surface metal plate that welds together along adjacent edge, and the number of plate depends on the cross section of access desired.For about 2 meters wide channel cross-sections, pipe A can only comprise two plates, is respectively the top board 2 that constitutes the base plate 1 of tubular shell bottom and constitute top, and described plate 1,2 is along their vertical

adjacent edge

11,21,11 ', 21 ' welding.Each plate 0,2 depends on conveying capacity along the length L that direction covered of the longitudinal axis 0,0 ' of pipeline.Plate 1a, the 1b of two continuous parts of pipe, 2a, 2b weld along their relative

widthwise edge

12a, 12b, 22a, 22b, bear the sealed tubular housing A of internal pressure so that constitute.

This tubular shell A is routed on the supporting mass B, and therefore this supporting mass B becomes U-shaped around the whole bottom of tubular shell, comprises pedestal 3 and two side direction wing plates 31,31 ', side direction wing plate 31,31 ' the two sides vertical lifting along housing A.This assembly is with respect to the vertical center plane P1 symmetry by longitudinal axis 0,0 '.

What two wing plates 31,31 ' of pedestal B upwards extended to pipe substantially passes through axis 0, the height of 0 ' horizontal diameter plane P 2, even also be higher than this plane in the embodiment shown in fig. 1 a little.

The two sides 13,13 ' of the base plate 1 of housing A also can be higher than plane P 2, because they are strengthened by two wing plates 31,31 ' of pedestal, therefore their vertical limit 11,11 ' keeping parallelism, and align with the corresponding edge of existing pipe section, this helps the installation and the welding of top board 2.Like this, the fan-shaped angle that base plate 1 covers becomes re-entrant angle greater than 180 °, and top board 2 covers the fan-shaped part of all the other angles.

The top of pipe 1 is made of the sidewall 13,13 ' of top board 2 and base plate 1, the sidewall 13 of base plate 1,13 ' with 2 tangent connections of top board, the shape of managing 1 top preferably the center 0, one section fan-shaped part of the rotating cylindrical on the 0 ' axis, and at least always down to diametral plane P2.Therefore, housing A can bear the load that applies with optimum state.In fact, the internal pressure that applies only is a tension load of having determined metallic walls, and this tension load calculates easily, and the thickness of this metallic walls is less relatively.Should be noted that

semicircular wall

2,13,13 ' makes it be in the optimum state of bearing internal pressure and external loading, for example, imbed under the ground and before in housing A, adding pressure fluid and can optimum state bear internal pressure and external loading at pipeline.

Bottom 1 is not a semicircle, even can be flat, because the pedestal 3 of concrete bearing body B and supporting mass reinforcement need be suitable for bearing flexural stress.

In the embodiment described in the inventor's the EP0767861 of patent application formerly, supporting mass is made of three parts, be respectively the lateral-supporting part of a pedestal that extends below housing bottom and two support shell body sidewalls, these two lateral-supporting parts press the side surface of pedestal by the pull bar of preload.

In this arrangement, the joint between two lateral-supportings of supporting mass part and the pedestal is in the hinge connection.

On the contrary, in the present invention, at least the lateral section 31 at the supporting mass B of housing A both sides partly is made of a single-piece, the cross section of this single-piece part becomes L shaped section, this L shaped section comprises a vertical substantially branch 32 and the branch 33 of a basic horizontal, this vertical branch 32 extends along the respective side walls of housing A, and this horizontal branch 33 extends below pipe, and constitutes at least a portion that is bearing in ground pedestal 3.

The continuity that such design can proof load be transmitted, thus the propagation stress that makes sidewall 13,13 ' by housing A be applied on two wing plates 32,32 ' of supporting mass B is absorbed by the pedestal 3 of described supporting mass.

Like this, can cancel the pull bar of preload, this pull bar is fastened in prior art embodiments in the pedestal, and therefore pedestal of the prior art will be subjected to very high compressive stress.In the present invention, pedestal only is subjected to the flexural stress that produces owing to sidewall 32,32 ' the trend of scattering, and it is compensated by the weight of pipe A and the pressure that is applied on its bottom surface 14.

Therefore, the pedestal 3 of supporting mass can be lighter, even for very heavy in section pipe, for example diameter is about 3 meters, also can form the supporting mass of single-piece, as shown in Figure 1.

Usually, supporting mass B comprises steel concrete, shown in the part section of Fig. 1.Reinforcement 5 must become suitable U-shaped, and can comprise the vertical enhancing steel bar 51 that links to each other with horizontal reinforcement 52 usually.

The radius of curvature of tubular shell bottom surface 14 can be greater than the radius of curvature of end face 2, even can also be flat.But, the bottom surface 14 of the basic horizontal of plate 1 and vertical substantially sidewall 13,13 ' abut on the inner surface 38 of L shaped part 31 of supporting mass B, preferably, one zone of transition is gradually arranged between vertical branch 32 and horizontal branch 33, so that the continuity that proof stress is propagated, and do not have any angle point.

For example, Fig. 2 has schematically illustrated the pipeline that comprises the metal tube A that links to each other with concrete pedestal B of the present invention with solid line, and has represented for example passing through to calculate determined distortion A ', B ' under the compressing of roadbed weight when there is excess pressure the pipeline outside with respect to pipe interior with blend.

Obviously, the ratio of distortion is exaggerated, so that can see clearlyer, but, should be known in because the propagation stress that is applied on the wing plate 32,32 ' of concrete bearing body B propagates on the

pedestal

3,33,33 ' of this concrete bearing body B continuously, make concrete bearing body B be out of shape gradually, therefore, two wing plates 32,32 ' make tubular shell locate to keep rigidity at the sidewall 13,13 ' of described housing, and do not have any danger of breaking at the position that is connected with concrete bearing body B.

Because stress well distributed in the volume of whole single-piece concrete bearing body B, the quality of described supporting mass can significantly reduce with respect to prior art embodiments.

In order to make this structure lighter, preferably can adopt " high performance concrete ", be somebody's turn to do the compression of " high performance concrete " and the ability to bear of stretching and be far longer than common concrete, for example surpass 40Mpa.Such ability to bear has strengthened interconnecting and cooperate between metal tube A and the concrete bearing body B.On the other hand, strengthen the reinforcing bar that concrete performance can adopt high ability to bear.Like this, the thickness of metallic walls can reduce, and therefore, the gross weight of element also can reduce.

And, shown in Fig. 3 and 4, can adopt angle bar 7,7 ' to strengthen connection between metallic walls A and the supporting mass B, each angle bar 7,7 ' forms an angle at least, the one side 71 at this angle covers each wing plate 32 of supporting mass B, 32 ' upper surface 30 ', and another side 72 extends upward and be tangent in the respective side walls 13 of the opening part of this supporting mass B and thin-walled A, 13 ' external surface.Limit 71 is enclosed in the concrete, and another side 72 is welded on sidewall 13,13 ' the external surface, therefore makes its reinforcement and is bearing on the wing plate 32,32 ' of supporting mass B, thereby can avoid because the danger that separation causes water for example to enter.

Angle bar 7,7 ' is furnished with enclosure portion 73, and preferably this enclosure portion can cover the outer ledge of the upper surface 30 ' of supporting mass B, to reduce the danger of concrete cracking.

Preferably, angle bar 7,7 ' whole surperficial 30 ' extension along supporting mass B, but they also can comprise the simple closed joint that is spaced apart from each other at a certain distance.

According to another particularly preferred feature, the formation of the stress continuous propagation in supporting mass B can simplification reinforcement is shown in Fig. 3 and 4.

At this moment, in fact this reinforcement can mainly be made of simple thin plate 54, and this thin plate 54 is with the curvature bending identical with the inner surface 38 of the wall 1 of housing A and supporting mass B, and described thin plate 54 embeds in the concrete 30.Porose 55 on the whole surface of thin plate 54, guaranteeing concrete infiltration, thereby interconnect better.And as shown in Figure 4, thin plate 54 can also all have protruding part 56 on two surface, so that interconnect fully.

Two parallel thin plates 1 are connected by concrete 30 with 54, and are combined together to form crooked crossbeam, thereby absorb sidewall 32,32 ' propagation stress.

In order to prevent cracking, in the bight of supporting mass B, it is just enough especially to place the wire gauze that a lighter reinforcement 5 ' for example welds along the external surface of this supporting mass.

As shown in Figure 4, owing to simplified reinforcement, therefore can there be free space in each corner at supporting mass, can place the pipe 58 of butt joint in this free space, the pipe 58 of this butt joint can be included among the supporting mass B, and the formation longitudinal space, cable, conduit or vertical preload bar pass through so that for example make.

According to another preferred feature as shown in Figure 4, concrete 30 can be a fibre reinforced concrete, and well-known, fibre reinforced concrete comprises a large amount of regular distribution in the concrete bearing body and the metallic fiber 57 of random orientation.Like this, this concrete bearing body B can be lighter.

Usually, for energy Random assignment metallic fiber 57, fibre reinforced concrete will adopt little filler, and bigger part is in fact also less than 8mm.And, all adopt additive to strengthen flowability, especially for high performance concrete usually.Therefore, in casting cycle, such concrete can be easy to flow in the reinforcement, thereby does not need vibration usually.

According to another preferred feature of the present invention, in order to guarantee the interlocking of concrete bodies and metal sheet roof covering A, one ripple connector can be installed on the external surface of metal sheet roof covering A, and this ripple connector preferably is made of the wire screen 8 that has vertical iron bar 81 and horizontal iron bar 82.This gauze can be buied by market, and can be for example by making it form ripple from passing between the roller that imbrication shape groove is arranged, and this parallel corrugation is in vertical iron bar 81.Such corrugated iron silk screen is easy to be out of shape in the horizontal, therefore can be attached on the outer surface part 14 of housing A, and concrete bodies then is attached on this housing A.The top 83 of this ripple can be with the known manner electric welding on the external surface 14 of wall 1, and it forms and loses mould (lost mould), as shown in Figure 6.When adopting short grained concrete, when especially adopting high-performance fiber to strengthen concrete, concrete can be penetrated in the part 84 of the wire gauze that extends between top 83, like this, this wire gauze is whole to be imbedded in the concrete, after concrete setting, between housing A and concrete bodies B, form good interlocking.As shown in Figure 6, on the top of concrete bodies B, the extension 85 of wire gauze 8 that can also be by suitable shape is arranged strengthens connection.Like this, the danger that can avoid water between housing A and concrete bodies B, to permeate, and can omit aforesaid angle bar 7.

And owing to adopted fibre reinforced concrete, aforesaid

other reinforcement

52,54 can omit.This feature has also strengthened the toughness of structure.

Because the present invention, the formation of prefabricated component and the implementation process that makes them constitute pipeline can be simplified.

Even for large scale very, the bottom 1 of tubular shell A also can be made of thin plate, this thin plate is bent or roll bending, so that obtain required radius of curvature.As shown in Figure 7, in order to make the prefabricated component of pipeline, with plate 1 upset and be placed on the bottom of mould 6, lose mould to constitute.This plate 1 encircles side in advance outside and forms interconnects 53, for example, and fabricated structural shape as shown in Figure 6 or be used to device that pipe is linked to each other with supporting mass.Behind side wall surface 61 that installs mould and reinforcement 5, casting concrete is until desired height, so that make pedestal B that required thickness be arranged.

Should be known in that the plate-shaped reinforcement among Fig. 3 and Fig. 4 can be installed on the plate 1 with required separation distance in advance.

After solidifying, this assembly is taken off and overturns from mould.

In order to carry the prefabricated component of such formation, obviously this prefabricated component must have anchor point on wing plate 32,32 ' top, for example encloses the ring 40 in the concrete, thereby hoist cable can be hooked it.When needing, this ring 40 also can be welded on the angle bar 7 that is enclosed on the supporting mass B upper surface 30 '.

Such prefabricated component can be transported to the job site at an easy rate, for example by trailer 62, as shown in Figure 6.Like this, very large prefabricated component also can transport by highway, as long as the height h of this prefabricated component adds the regulation that still meets this highway behind the height of trailer.In fact, as long as like this length L of prefabricated component is described just passablely, that is, this prefabricated component laterally is placed on the trailer, can not surpass the width of permission generally.

The top board 2 of pipe is made of bending plate, and it can be simply stacked, so that be transported to the scene.

In order to form this pipeline, after being ready to installation surface C, with this prefabricated component axis longitudinally 0 one by one, 0 ' places, adjust height and position simultaneously, so that side 11a, the 11b of plate 1a, the 1b of the prefabricated component B1 that will install and mounted prefabricated component B are in alignment with each other, thereby corresponding widthwise edge 12a, 12b are in contact with one another.

Then top board 2a can be installed, assembly can be distinguished longitudinally joint 11,21 and transverse joint 12,22 welding.

At each vertical end place of prefabricated component, concrete bearing body B stops and concaves from thin plate 1 a little, so that stay at interval 34 between two adjacent elements B1, B2, thereby makes that the welding of the installation of prefabricated component and thin plate is easier.Reinforcement 51 has slave part longitudinally, and this slave part is intersected with each other in interval 34, is embedded in then in the mortar of sealing.

Therefore, the formation of this pipeline is very easy to, and this is because element can be prefabricated in factory, is transported to the job site then.

But, for very large size, also can form this element at the scene.In fact, thin plate 1,2 can form and be stacked on the trailer in the workshop and deliver to the scene, and it need cooperate with required mould 6, so mould is simple especially.For bigger pipeline, this element can be made near on-the-spot mobile pre-control equipment.

Obviously, if supporting mass B can do gentlyer, then must calculate with respect to used environment.For example, when pipeline was positioned at phreatic table (groundwater table), therefore this concrete bearing body can determine its quality preferably as counterbalance.

But the present invention obviously is not limited to the details that the foregoing description is introduced, and this is because under the situation that does not break away from scope defined by the claims, other embodiment can be arranged.

For example, in order to make supporting mass lighter, can be as shown in Figure 3, make tubular shell A have circular contour, like this, this tubular shell A self can bear internal pressure, and can on pedestal 3, not apply any flexural stress, this pedestal 3 mainly makes housing have rigidity, and especially in assembling process, and this pedestal can be with load distribution to big surface.But, the overall height H of this element will increase, and therefore, under the situation of major path cross section, preferably adopt the embodiment of flat base as shown in Figure 1 usually.

And, according to Fig. 7, become two-part tubular shell structure to be particularly advantageous in the very large pipeline of cross section, still, because the advantage that is had, the present invention also can be used for the pipeline of general size, and for example diameter is 0.5 meter a pipeline.At this moment, preferably directly use closure tube.

For example, in known technology, can carry out the bias voltage roll-in to the thin plate of length very, and adjacent volume side is welded, to constitute the tubulose closure shell, again this tubulose closure shell is cut into smallclothes, its length and carrying and conveying capacity adapt.

Such tube-like piece can be placed between the two side of mould, and this mould has two bases in each side of pipe, and this base places enough height, for example arrives the middle part of this pipe.Again interlocking part such as ripple gauze 8 are contained on the projection on this pipe top.As previously mentioned, then can be in the mould of such formation casting concrete, highly be higher than the top of pipe up to it, thereby make concrete bodies have the thickness of regulation.

On the other hand, although adopt the single-piece concrete bearing body advantageous particularly of U-shaped, also can be as shown in Figure 5, provide two horizontal branch 33,33 ' L shaped part 36,36 ' are arranged, its central plane P1 place at pipeline is continuous.Then, constitute this housing, so that between two branches 33,33 ' opposite face, stay a free space 37, in this free space 37, the auxiliary reinforcement in two elements is intersected with each other and cooperate with vertical reinforcement, then, this assembly is imbedded in the sealing mortar, so that this pedestal is continuous.

In addition, the height of landing

edge

11,21 can change, and sidewall 32,32 ' height (h ') also can change, but this sidewall 32,32 ' must have enough height, so that make during step-down sidewall 13,13 ' keep rigidity and the extrusion stress of bearing this pipeline with respect to external environment condition.

Obviously, this concrete bearing body B must enough can bear carrying, conveying and the installation of prefabricated component.In fact, because the interlocking between metallic walls A and the concrete bodies B, so whole rigidity strengthens.But, light as far as possible in order to make supporting mass B, can strengthen with the connection crossbeam that is installed in two wing plates 32,32 ' upper end sometimes, so that the parts below making in handling process have rigidity.Should support crossbeam removably to install,, thereby top board 2 was installed so that behind the parts below installing it is pulled down.But, this connection crossbeam is still very beneficial after pipeline constitutes.In fact, as shown in Figure 8, it can form the support 41 of mechanical welding structure, and across pipeline, its interior shape 42 is consistent with the shape of upper wall surface 2.When supporting mass B was enough to bear the carrying operation, this support 41 also can be pre-installed on the top board 2.Support 41 can provide outer protection and reinforcement plate 2, and the thickness of plate 2 can reduce, and described thickness can only calculate by the tension load that causes owing to internal pressure.Like this, the plate 2 that strengthens by one or several support 41 can bear extruding during step-down better at pipeline with respect to external environment condition.

Pipeline of the present invention also has other advantage.

For example, at the sweep of pipeline, adjacent concrete element can interconnect, so that prevent the pipeline slippage.As shown in Figure 9, this prefabricated component is easy to such formation, that is, the transverse joint plane Q at transverse edge 12,22 places of housing A is with respect to the longitudinal median plane P1 of each prefabricated component and tilt, so that can progressively change direction.The pull bar 43 that adjacent element passes through preload again is and interconnected, and this pull bar 43 preferably inserts in the pipe shown in Figure 4 58, and its end is pressed against on the boss 35 in each element B1, the outside, B2 end.

Similarly, as shown in Figure 9, joint plane Q also can tilt with respect to horizontal axis, so that be suitable for laying the inclination angle variation of surface C.

As shown in Figure 6, as mentioned above, in order to guarantee concrete bodies B and the interlocking of pipe between the A, preferably on pipe A corrugated wire gauze 8 is installed, this corrugated wire gauze 8 is very cheap and can form at an easy rate.But, such concrete infiltration that can allow also can become corrugated porose plate also can otherwise obtain, for example: by form a kind of grid with grid, perhaps obtain caillebotis by thin plate is torn into blade.

And obviously, the feature and the characteristic that constitute the wall of pipe A must be suitable for fluid that is transported and the pressure that is born.

Should be noted that the special construction of this pipeline can reduce the thickness of tube wall with respect to the common metal pipeline.Like this, can make this pipe with specific metal, for example use stainless steel, at this moment the cost of Zeng Jiaing can compensate by the cancellation lining, and this lining need be used to improve flow regime usually.

At this moment, be more preferably as shown in Figure 6, by corrugated wire gauze improve the pipe and concrete between interlocking.

In claims, the reference number that is inserted behind the mentioned technical characterictic is just understood in order to be more convenient for, and anything but to the qualification of its scope.
