Abstract
A traffic pavement for high-speed transportation, especially magnetic levitation railway (TRANSRAPID) has the prefabricated supporters installed to the concrete bed. Said supporter is composd of at least one longitudinal ribbed hollow prestressed concrete beam and pave slabs transversely and continuously laid on said longitudinal beam. Said prestressed concrete beam has the bearing tubes and bearing shoulders for said pave slabs. Said longitudinal beam features simple structure, low cost, thin thickness and light weight.
Description
The present invention relates to a kind of land transportation route that is used for, be preferably used for magnetic levitation railway, the driving road surface of TRANSRAPID for example, comprise the preformed part driving road surface carriage that is contained on the basis of making by the frame mode of concrete in situsd or preformed part, it has the prestressed concrete longeron of a hollow arrangement of reinforcement at least; And comprise the roadway panel of making independent member that stretches out from prestressed concrete longeron both sides continuously transverse to moving traffic lane.
By the known this driving of DE 29809580 U1 road surface, there, driving road surface longeron is made with steel.
But suggestion equally similarly with it, because steel structure corrosion-vulnerable and noise are greatly and the unfavorable factors such as environmental pressure that cause thus, so far precast concrete driving road surface carriage (Fahrwegtraeger) (to this can for example referring to DE 4115936 A1) is designed to have the prestressed concrete longeron of the hollow arrangement of reinforcement in trapezoid cross section, extends with the right side left in its superposed bigger base.Usually this lengthening is designed to until driving ground-surface overall with, so roadway surface bearing and the guidance system parts (side guide, sliding bearing lath and stator lasmination (Statorpakete)) in roadway face side direction also need only be installed.
A kind of like this prestressed concrete longeron just can be made the vibrated concrete moulded parts to a certain extent economically, and it requires especially at end fan arrangement of reinforcement.This requires in fact again in being used for the end region of configuration reinforcement is solid cross-sectional plane, and also needs at least 30 to 40cm wall thickness all the time in hollow and central area, so that guarantee necessary strength in by the concrete making method that vibrates.These difficulties exist in a kind of mixed system in principle equally, and the side arm of prestressed concrete longeron is not designed into driving ground-surface overall with in this mixed system, but will lack.Mode size with complexity on short arm accurately is screwed the steel member, the latter itself again formation or fixed bearing and guidance system at the parts of roadway face side direction.Here, there is the prestressed concrete longeron of galianconism also must be by the manufacturing of vibrating in mould, from and bring above-mentioned problem with big weight, this has not only increased the consumption of material, but also makes and to cause undesirable preformed part operating difficulties when installing on-site.
Therefore the objective of the invention is, design the driving road surface that the described type of a kind of preface is used for magnetic levitation railway, make the prestressed concrete longeron can be simpler, more cheap and have littler wall thickness and thereby lighter weight is arranged make.
Stipulate that one or more prestressed concrete longeron is designed to make, as to have the upper support convex shoulder that is used for roadway panel prestressed concrete support tube by the present invention for reaching this purpose in centnifugal force concrete production process.
By supporting member and roadway panel are separated, wherein the roadway panel both can be that the concrete slab of arrangement of reinforcement also can be a steel plate structure, in other words by the cancellation supporting arm that side direction is used with concrete depositing up train road surface on the prestressed concrete longeron, the prestressed concrete longeron can be processed into the centnifugal force concrete component of tubulose symmetry basically.This centnifugal force cement concrete product not only can reduce wall thickness and thereby expendable weight, and can obtain the beam of continuous hollow in this way, it has the space of big perforation can be provided for cable laying and supply line in inside.Supporting shoulder should be especially constitutes from the strengthening rib that columniform tubulose basically stretches out by side direction in this case, and the much bigger dimensionally flange that overhangs of these strengthening ribs and driving road surface carriage so far is incomparable.By means of the rib that stretches out to obtain more bigger areal of support, can keep the overbalance of beam enough little, this in addition overbalance also can take other measures further to be compensated (also can describe in detail below this) when producing, thereby can implement simple centnifugal force concrete production.
Different with the structure of the long preformed part driving road surface carriage of nearly 20m-31m, further develop by of the present invention, the roadway panel is made up of the driving road surface individual plates that polylith follows the long partition distance of the short preferably about 6m of bus or train route line direction.These plate sections are different from the roadway panel of existing direct cast concrete and can very rapidly change, under the situation of safeguarding or repairing, can remove from the standard beam one by one, thereby repair also very convenient, especially when preferably being made as steel plate structure, can milling and thereby accurately processing on lathe easily.A piece plate that constitutes the roadway panel can be similar to existing sleeper system and simply and durably be fixed on the prestressed concrete support tube with screw.Another advantage that should particularly point out is that these individual plates can accurately assemble.
The roadway panel of the preformed part of approximately long 20m-31m driving road surface carriage is divided into a plurality of individual plates also has an advantage to be, these individual plates can be more convenient and also can be processed more accurately and be more convenient for to operate.In addition, the advantage that the roadway panel is divided into individual plates and provides is, can obtain the driving road surface of lateral inclination more simply at segment of curve, and especially can design the transition region between the section of different gradients easily.
Usually the high heal differential that occurs in roadway face carriage is (at the roadway panel on top by solar irradiation warm, and the prestressed concrete longeron that is arranged in the bottom is in shade and thereby colder) and the high stress that causes thus, because roadway panel (they preferably also are divided into some individual plates again) is screwed, can bear better compared with connecting into single-piece roadway panel with driving road surface carriage.Compare with the steel driving road surface (longeron also is designed to girder steel there) that a kind of weight is lighter equally, far better by common toot the characteristic of the sound of structure of the present invention, and especially do not need antirust yet.
In the driving road surface guide piece that usually adopts so-called A type buttress supporting, the prestressed concrete support tube that is in central authorities with respect to the roadway panel should establish pouring concrete afterwards fixing be bearing in support (Stuetzkonsole) on the buttress.For this reason, can be embedded in thread bush at the prestressed concrete support tube, be used to screw in the anchor pole that is inserted in the support, in addition, the prestressed concrete support tube additionally has rough surface at the supporting area of support, so also guarantee thus to be connected better between prestressed concrete support tube and support.
In order in segment of curve, to make roadway side superelevation (Ueberhoehung), the separation beam of can between the supporting shoulder of prestressed concrete support tube and roadway panel, packing into, or, especially in segment of curve, under the king-sized situation of superelevation, prestressed concrete support tube rotation back is fixed on the support with cement concrete.
By roadway mask of the present invention the design of the prestressed concrete support tube of making is arranged in centnifugal force concrete production process, in the driving road surface of (ebenerdig) driving road surface guide piece, also can use with flying colors with bottom.To this, so far or adopt a continuous central support wall, or adopt a plurality of lateral support walls transverse to the moving traffic lane narrower and small spacing of being separated by (3 to 5 meters of spacings) that place, low, preformed part driving road surface bearing bracket is on them.Because the vehicle structure of fast traffic surrounds driving ground-surface sidewall, also requires to be higher than about 80 to 100cm from ground in the guide piece of the driving road surface of so-called bottom.Employing by short spacing lateral support arranged side by side each other except that raising the cost, this frame mode is because these big weight of lateral support that is anchored at dearly in the ground also causes high interference noise burden (very loud chatter sound), because because high road speed especially causes lasting airstream eddy current on the lateral support wall.
For avoiding above-mentioned situation, stipulate in the guide piece of the driving road surface of bottom by the present invention, the prestressed concrete support tube that adopts two spacings of being separated by abreast to be connected to each other in supporting area together directly is bearing on the concrete foundation, and their common rests preferably are designed to the roadway panel that the form of plate section is one by one made independent member.For this reason, the prestressed concrete support tube should have side direction to scabble face at upper support convex shoulder side burr, so although their spacings of being separated by are provided with mutually side by side when about 80cm highly, overall width is still much smaller than driving ground-surface width.Except the advantage of top relevant generation noise aspect of having touched upon, is the structure that 60 to 80cm rectangular tube constitutes by the present invention by directly being bearing in the prestressed interconnected height of centnifugal force tamping on the ground, and its advantage is a per unit apart from the basis of needs seldom.Every so far 6.20m roadway panel must be established three bases, and by in the structure of the present invention, has two bases that are located at the termination just enough on the total length of prestressed concrete support tube 20m-31m.This means when building the driving road surface and significantly simplify.
In addition, the clearance envelope in centnifugal force rectangle pipe is applicable to protectorate installation cable and supply line.Basically the prestress support tube that is designed to rectangular tube particularly advantageously side is connected one with screw and is designed to rectangular section and itself available screw and concrete foundation in supporting area on the bonded assembly steel frame.
In the driving road surface guide piece of bottom with centnifugal force prestressed concrete rectangular tube of installing by setting of the present invention, they can be bearing on the concrete foundation by the wedge shape intermediate beam, so do not need for each gradient has special driving road surface carriage, this then special driving road surface carriage requires special-purpose centrifugal mold again.
Adverse effect for fear of preformed part driving road surface carriage self bending of laying along long distance with overhanging, can stipulate on the one hand, the prestressed concrete support tube is made upwards slightly protuberantia, make they at bearing state owing to conduct oneself with dignity and the weight that is bearing in the roadway panel above them is in horizontal surface position accurately.Upwards the size of protuberantia can be designed as on the other hand, and this level attitude also can be issued in the situation of driving load.
In addition, in order in the lower region of prestressed concrete support tube, to bear vehicle weight, in this zone, can adopt by enhancing arrangement of reinforcement thick and/or that compact arranged deformed bar constitutes.
In order to make by prestressed concrete support tube of the present invention, adopting the centnifugal force concrete mould by regulation in the design of the present invention, wherein, the template of determining prestressed concrete support tube profile is added with the strengthening rib around the rotation axis distribution or asymmetrical distribution in such a way, that is, by they and in conjunction with the deformed bar of distribution or asymmetrical distribution can balance because at the more overbalance that causes of supporting shoulder zone inner concrete part.By this unbalanced automatic compensation, certainly this is not for no other reason than that this roadway panel has direct forming to be fixed on roadway face carriage but as single member under the situation on the prestress support tube of making in the centnifugal force concrete production process just might take place, the concrete production of centnifugal force can very economical ground and have quite high rotating speed and thereby high cement concrete density and correspondingly small wall thickness ground realize.
Provide other advantages of the present invention, feature and details by following to the explanation of several embodiment and by accompanying drawing.Wherein:
Fig. 1 is by the section by preformed part driving of the present invention road surface carriage;
Fig. 2 does not have the roadway panel at two connector area driving road surface lateral plans of pressing the preformed part driving road surface carriage of Fig. 1;
Fig. 3 has the driving ground-surface driving road surface diagrammatic side view of side superelevation at segment of curve;
IV and V are local among Figure 4 and 5 Fig. 3 amplifies the wedge shape support design of expression roadway panel on the prestressed concrete support tube;
Fig. 6 is corresponding to the scheme drawing of Fig. 3, and here, the side superelevation in the segment of curve reaches by additionally rotating the prestressed concrete support tube;
Fig. 7 by driving ground-surface section, comprises that two are connected to each other the centnifugal force prestressed concrete support tube that is designed to rectangular tube basically in the same high driving road surface guide piece with the road surface;
One section birds-eye view in Fig. 8 driving road surface shown in Figure 7, wherein polylith roadway panel is placed on two rectangular tubes;
Fig. 9 is by driving road surface and the corresponding section of Fig. 7 in the superelevated curve section;
The amplification profile of the prestressed concrete support tube of Figure 10 by having the deformed bar that schematically illustrates; And
Figure 11 is by being used to produce the constructed profile by the centrifugal mold of prestressed concrete support tube shown in Figure 10.
The driving road surface guide piece of representing in Fig. 1 and 2 that is used for supporting structure (has only schematically shown many meters high buttress 1 at Fig. 2, in Fig. 1, cast out fully) the driving pavement structure, mainly form by prestressed concrete support tube 2 with as the roadway panel 3 that independent member is made, wherein these roadway panel designs are different with prestressed concrete support tube 2 length, and they are made of the short individual plates of some length.This just might irrespectively be designed to the concrete slab of arrangement of reinforcement with the making of these roadway panels 3, or is designed to steel plate structure as shown in the figure, makes the processing of roadway panel very simple.But especially roadway panel and real longeron can also be separated fully, longeron be designed at least substantially symmetry and thereby only show unbalanced pipe in a small amount, therefore it can make in the process of centnifugal force concrete production.The whole top-out that comprises roadway panel 3 often with load-bearing upwards vertical control member in aggregates of the trapezoidal cross-section of broadening arranged mostly, this just may reasonably adopt the centnifugal force concrete production hardly.In addition, this member is under any circumstance all operated with its production method is irrelevant as a whole.Because the big wall thickness of prestressed concrete longeron of jolt ramming causes big weight to add the weight of the roadway panel of unitary fixed on it, make the surface accuracy of the preformed part driving road surface carriage of laying the about 20m-31m of this scantling length and assurance roadway panel become a kind of complex installation process.
In order to constitute the supporting shoulder 4 that can be screwed roadway panel 3 corresponding supporting sections 5 on it, only need to stretch out strengthening rib 6 from prestressed concrete support tube 2 columniform tubuloses slightly, they do not bring tangible overbalance, do not have overbalance and do not have asymmetric then may with centnifugal force concrete production contradiction not.
Adopt the centnifugal force concrete production that the internal cavities 7 of a big perforation is provided, it can be used to cable laying and supply line.In the centnifugal force concrete production process of prestressed concrete support tube 2, in the supporting area on buttress 1, that is, embed thread bush 8 usually in the termination of the long prestressed concrete support tube of 20m-31m.Anchor pole 9 can screw in wherein.Anchor pole is used for being anchored at support 10, and prestressed concrete support tube 2 is bearing on the buttress 1 by means of support 10 with roadway panel 3.The additional here preferably elastomeric stent foot 11 that is provided with is known, does not therefore need here to be further described.The roadway panel separates with prestressed concrete support tube 2, makes that the moving traffic lane superelevation in the segment of curve can very realize simply, as shown in Fig. 3 to 5.For this purpose, only clap board 12 and additional distance plate 13 need be installed in the non-breathing zone of roadway panel 3 on support tube 2.Replace these or in case of necessity except that these, also can stipulate that the prestressed concrete support tube rotates around its longitudinal axis by Fig. 6, just for example suitably rotation back pouring concrete be fixed on the support 10.Especially in pressing this driving road surface superelevation device of Fig. 3 to 5, with the roadway panel designs is to be divided into the short individual plates of a piece outstanding advantage is arranged, because so in having a long preformed part driving road surface carriage of 20m-31m, needn't keep constant same slope, but the long individual plates of 6.2m of respectively having an appointment can have different gradients.
Fig. 7 and 8 schematically illustrates in the same high driving road surface guide piece with the road surface by driving ground-surface section-drawing and birds-eye view.Can find out that in the drawings one or more has the long roadway panel 3 of about 6.20m, they are screwed prestressed concrete support tube 2 ' on bearing mutually side by side and by means of rectangular steel pipe 14 together by two spacings of being separated by abreast, directly are bearing on the ground 15.Additionally also can establish the ground 15 of anchor pier 16, need only be by a length with preformed part driving road surface carriage, that is the corresponding spacing of about in the present embodiment 20m-31m is provided with respectively, and on the basis that needs to decuple this by means of by the lateral support wall supporting preformed part driving road surface carriage of 3 meters pitch arrangement the time nearly.Except the cavity 7 ' of the prestressed concrete support tube 2 ' internal run-through that is designed to rectangular tube basically, the space between the prestressed concrete rectangular beam also is specially adapted to hold cable and supply line.
Fig. 9 represents the cooresponding section with Fig. 7, is located at the clap board 17 of basis on 15 by one here and can obtains driving road slope as the segment of curve superelevation.
Figure 10 represents the section by 2 amplifications of prestressed concrete support tube, has also schematically illustrated the deformed bars 20 or 21 that are arranged in the different face of cylinder 18 and 19 among the figure simultaneously.Deformed bar is closely arranged back to the lower part of supporting shoulder 4 at prestressed concrete support tube 2, also designs more in case of necessity, so that obtain more arrangement of reinforcement at this bottom loading zone that especially is being subjected to produce big pulling force under the weight effect.The distribution or asymmetrical distribution of present this arrangement of reinforcement can be combined in that the centnifugal force concrete mould is inner to be the set asymmetrically distributed supporting rib 22 of reinforcing template 23, be used to make the weight of the steel that in the prestressed concrete support tube lower region that will make, increases to be equilibrated in the zone of supporting shoulder and the strengthening rib 6 that stretches out more weight concrete just, thereby avoid producing overbalance, so the centnifugal force concrete production can and be carried out under extra high rotating speed by simple especially mode.
