Abstract
A reinforced concrete structure comprises a reinforcement (1, 11) made from a plurality of elongate longitudinal members (2, 12) of fibreglass or like material, disposed substantially parallel with one another in at least one predetermined direction. The elongate longitudinal members are coupled to one another by means of coupling members (3, 13) of fibreglass or formed by a strip of flexible polymer material. Metal and/or synthetic fibres are mixed with the concrete matrix to provide the structure with shear strength, making it possible substantially to reduce the number of coupling members (3, 13).
Description
Technical field
The present invention relates to for the manufacture of the reinforcement of underground reinforced concrete construction, structure and method.
Background technology
Develop the present invention based on specific reference, but the present invention is not limited to constructs tunnel wall and tunnel shaft during evacuation works.
Known to " tunnel boring machine " (TBM) tunneling in excavator, usually first transfer excavator from reinforced concrete vertical shaft structure, described reinforced concrete vertical shaft structure is designed to comprise the soil body around tunnel portal.Traditionally, vertical shaft is by trending towards parallelepiped shape and the concrete diaphragm excavating on the spot in the soil body and pour into a mould is formed, or vertical shaft is made up of the circular stake be driven into before tunneling initial part in the soil body.
Excavator shifts out in the end in tunnel via the vertical shaft of constructed earlier usually.And quite generally, along with the propelling of evacuation works, the path along tunnel provides similar ventilation or enters platform or provide other reinforced concrete structure and dividing plate.
One of significant challenge faced makes tunnel boring machine by these steel concrete dividing plate or structure, and described steel concrete dividing plate or structure are strengthened by reinforcing bar and steel bar to bear the moment of deflection and load that are applied by surrounding soil.Be very difficult to due to iron bar and their inherent ductility in practice destroy steel concrete, described iron bar and their inherent ductility almost prevent all excavators by these structures.
Due to this reason, describe a kind of enhancing technology for concrete structure not long ago, described technology can not prevent excavator from passing through.At this also known as doing in the technology of " passing through district (softeye) " opening, through in the region of concrete structure, steel reinforcement to be substituted with glass fiber reinforcement part at excavator.Especially, known to multiple longitudinal member generation " passing through district ", described multiple longitudinal member is formed by the glass fiber bar kept together with multiple bundled piece, and described multiple bundled piece relative to no matter is suitably shaped for wall or for the geometry of the underground structure of stake.
In the enhancing structure for constructing tunnel, use glass fiber reinforcement part to contribute to excavator operation, described excavator advances with a speed, described speed be not less than when these excavators meet with such as rock and non-reinforced concrete there is the material of similar compressive strength time speed.
Glass fiber typically has the tensile strength being greater than iron, but but more fragile, thus causes fluoropolymer resin longitudinally to be collapsed when glass fiber ruptures.Must consider these performances when producing and there is the concrete structure of glass fiber reinforcement part, and the quantity of longitudinal member and the quantity of bundled piece are especially far longer than the conventional steel bar concrete structure of the steel reinforcement with similar strength for this reason.In brief, the framework formed by glass fiber longitudinal member and the bundled piece for steel concrete or cement is much finer and close than the similar conventional frame formed by steel longitudinal member and bundled piece.
There is above-mentioned defect when using glass fiber reinforcement part in reinforced concrete construction, because a large amount of longitudinal member of needs and bundled piece obtain gratifying intensity, cost is high in reinforced concrete construction.Financial cost is being specific defect for being intended in temporary transient engineering (such as when excavator is by interim underground construction destroyed during interim underground construction).
And glass fiber reinforcement part is more complicated than traditional steel reinforcement manufacture.Even if although reinforcing bar is also easily deformable with the bundled piece producing desired size when low temperature, glass fiber bundled piece must be shaped during fabrication in advance, result causes production in enormous quantities cost more high, complicated and can cause problem.In other words, assemble glass fiber reinforcement cage or framework in the mode identical with the steely cage of class or framework, essential difference can not bend at the scene and welding glass fiber bundled piece, but glass fiber bundled piece must be prepared in factory.This makes complex structure and makes to manufacture, transport and install the concrete structure more difficult strengthened by glass fiber reinforcement part, especially when constructing underground structure.
Summary of the invention
The present invention proposes to have with relative these and other defect that the cost-benefit reinforcement for firmly subsurface structure, structure and method solve prior art by being easy to produce.
To achieve these goals, the present invention relates to for the reinforcement of underground reinforced concrete structure, structure and method, described reinforcement, structure and method have feature described in the following claims.
In one embodiment, with multiple longitudinal member manufacture, there is the glass fiber of the material of similar strength and brittle behavior, reinforcement, cage, framework or framework, described multiple longitudinal member (preferably having the Fiber glass rod of smooth or ripply external surface) is arranged to be parallel to each other and is kept together by multiple coupling member, described multiple coupling member preferably but be not flexible in the plane in the basic direction transverse to Fiber glass rod exclusively, makes reinforcement can manufacture compact so that transport.
Just to providing the reinforcement with prespecified geometric, reinforcement can also comprise limited multiple be also the relatively firm coupling member of glass fiber, such as bundled piece etc.In other words, bundled piece can not have foundation structure function and can not play a significant role when calculating underground structure intensity.Than the prior art of the rigid binding part of use much larger number, a small amount of glass fiber bundled piece makes not too to be difficult to construct reinforcement.Fluid concrete holds metal and/or the synthetic fibers of some with the concrete comprising glass fiber reinforcement part, and described metal and/or synthetic fibers give concrete sizable shear strength, especially when high surface area.Surprisingly, even if when fiber is metal, excavator also can not be prevented to be easy to penetrate its structure and to destroy this structure by fibre-reinforced this concrete.And the Fiber glass rod self forming the longitudinal member of reinforced concrete structure of the present invention provides excellent bending strength because of the vertical continuity of the glass fiber in rod.By comprising metal at cement aggregate and/or synthetic fibers are that reinforced concrete construction provides shear strength.
Flexible bundled piece component is preferably made up of polymeric material material strip, manufactures described polymeric material material strip by the very firm synthetic fiber bundle be included in robust polymer jacket.
Accompanying drawing explanation
Only by the mode of non-restrictive example, in the following detailed description of the embodiment that reference accompanying drawing provides, set forth further feature of the present invention and advantage, wherein:
Fig. 1 is used to produce the perspective illustration for an embodiment of the glass fiber reinforcement part of the stake of underground reinforced concrete structure;
Fig. 2 is used to the perspective illustration that production is provided with another embodiment of the reinforcement of the ground lower clapboard of " passing through district ";
Fig. 3 is the schematic diagram comprising the cross section of the ground lower clapboard of " passing through district " obtained by the reinforcement of Fig. 2.
Detailed description of the invention
Fig. 1 is used to produce the perspective schematic view for an embodiment of the glass fiber reinforcement part 1 of the stake of underground reinforced concrete structure.Glass fiber reinforcement part 1 comprises multiple glass fiber longitudinal member 2, described multiple glass fiber longitudinal member 2 is substantially spaced from each other and extends in parallel to each other, and arranges in the mode substantially similar with the known metal longitudinal member for reinforced concrete structure.Longitudinal member 2 keeps putting in place by coupling member 3, is spaced from each other compared with described coupling member 3 and known reinforcement with specific interval.Coupling member 3 can be attached to longitudinal member 2 by conjunction, holder etc., or can be connected by adhesive or other similar fashion.
Coupling member 3 also can be made up of glass fiber, assist thus and reinforcement 1 is kept its prespecified geometric (shape of the cylindrical shape such as shown in Fig. 1 or any expectation, typically parallelepiped), to construct wall as shown in Figures 2 and 3 or dividing plate.In this case, preferably manufacture reinforcement in the factory, subsequently reinforcement is transported to it and makes land used.
In an alternative embodiment, coupling member 3 is made up of polymeric material material strip, and described polymeric material material strip is made up of the high strength synthetic fibre bundle being included in robust polymer jacket.The example of bar being particularly suited for applying be applied in the soil body to strengthen in section and commercial be called manufactured by OfficineMaccaferriSpA ParaWeb (
tM) bar.The use of flexible connected component 3 means by gathering longitudinal member 2 and compacting reinforcement, makes land used to contribute to them to be transported to from manufactured place.Bar for the manufacture of coupling member 3 makes to gather longitudinal member 2, but but prevents their axially relative movements.In other words, but not preferably flexible in the plane of the basic axial direction transverse to Fiber glass rod exclusively as the bar of coupling member 3, reinforcement can be compacted to transport, and can open until become the geometrical construction of expectation easily by the maximum extension that can realize as the bar of coupling member 3 along horizontal direction movement space by making longitudinal member 2 subsequently.
Longitudinal member 2 preferably but do not have exclusively and be greater than about 28mm and preferably but be not less than the diameter of about 42mm exclusively.Although the preferred size of longitudinal member 2 depends on the particular design of underground structure to be constructed, but should be understood that, because the longitudinal member of relatively large amount must be provided to provide required intensity to bear the power applied by surrounding soil for subsurface structure, so use the longitudinal member of small diameter not too favourable.The longitudinal member that diameter is greater than specified size is also not too preferred, and this postpones owing to transmitting shear stress, and the glass fiber near the center of the cross section of rod does not bear the stress equally large with the stress born by the fiber near external surface.This problem causes the rod than having small diameter usually, has that the intensity of large diameter Fiber glass rod is all relative with validity to be reduced.
Fig. 2 is the perspective schematic view of the structure of " the passing through district " with reinforcement 11, described reinforcement 11 is similar with the reinforcement of Fig. 1, but there is parallelepipedal geometrical construction, wherein, also longitudinal member 12 is become by elongated glass fibers clavate, the smooth outer surface of described elongated glass fibers rod or preferably become corrugated, and described longitudinal member 12 is spaced from each other and is parallel to each other and is kept together by coupling member 13.As mentioned above, coupling member 13 can be rigidity (such as glass fiber bundled piece) or can be preferably flexible (such as using the polymer strip of the above-mentioned type).
Be fixed to traditional steel reinforcement 10 as the glass fiber reinforcement part 11 passing through district, described conventional steel reinforcement 10 is such as formed by steel longitudinal member 15 and steel bundled piece 16 by part 17 of tying.The height D of the glass fiber reinforcement part 11 of steel reinforcement 10 is not had at least to equal to excavate the excavation size of rig, as will be described in detail below.
As can be seen from the schematic cross-section of Fig. 3, during use, in the process excavating soil body T, reinforcement 11 is comprised (and when structure passes through district by using, also comprise steel reinforcement 10) concrete aggregate 21, reinforcement 11 forms the reinforcement of underground concrete structure 20, underground concrete structure 20 described in the technical construction known by underground engineering field.
According to special characteristic, concrete aggregate 21 comprises multiple metal and/or synthetic fibers in inside.The example of this fiber be the trade mark manufactured by OfficineMaccaferriSpA be called Wirand (
r) fiber.When concrete is in fluid state, when metal and/or synthetic fibers mix with concrete, metal and/or synthetic fibers are randomly dispersed in concrete.Fiber to be included in concrete aggregate and to provide enough shear strengths to strengthen bundled piece to eliminate or at least significantly to reduce transverse direction required in glass fiber reinforcement part 11 for concrete aggregate.
Carry out productive structure by means of steel concrete of the present invention and follow following program, described program is different from the program being generally used for underground reinforced concrete construction, and for non-pro personnel, use the present invention to implement this program at the construction field (site) particularly simple.
Previously prepared fiber rod, described fiber clavate becomes to represent the longitudinal member 2,12 of above-mentioned reinforcement 1,11.Coupling member 3,13 can be made up of glass fiber, and in this case, the previously prepared one-tenth of coupling member 3,13 have for the particular design that will apply standard or the size of customization and measured value.In any situation, even if relatively few quantity of coupling member 3 means that their manufacture also has economy relatively for particular design customization.
In the embodiment of coupling member 3,13 flexibility, such as use above-mentioned polymer strip, manufacture reinforcement 1,11 and particularly have economy and favourable, reason is to contribute to producing by bar (such as coupling member) being cut into appropriate size and reinforcement compacting made them can be transported to structure the making land used of underground structure to have also for the geometry of particular design customization and the reinforcement of size.
At the construction field (site), reinforcement 1,11 is first by arranging longitudinal member 2,12 with predetermined geometry, and longitudinal member 2,12 is kept putting in place by being fastened to coupling member 3,13 when coupling member 3,13 is rigidity, or by flexible member (such as, aforementioned polymer bar) or play in a similar manner function component formed coupling member 3,13 when by launch previous compacting reinforcement and by longitudinal member 2,12 keep put in place.
After excavating soil body T by known method, columniform reinforcement 1 is inserted in described soil body T such as to form stake, or the parallelepipedal reinforcement 11 being such as connected to reinforcement 10 is inserted in soil body T and passes through district, for throwing in tunnel boring machine to be formed in dividing plate or vertical shaft.Be poured into by concrete subsequently in excavation portion, described concrete is prepared at the scene or is manufactured in remote factory and be transported to scene by concrete mixing machine.Metal and/or the synthetic fibers of concrete aggregate and well-known type mix, and this well-known type is such as type disclosed in the applicant patent application EP0475917 under one's name.Fiber can mix with concrete according to method disclosed in the applicant document WO2011/015966 under one's name.After concrete hardened, the structure of underground structure is completed at fluid concrete.
The feature of the structure provided by this way is: its compressive strength provided by concrete, its flexural strength provided by glass fiber longitudinal member and its shear strength substantially provided by the fiber be included in concrete substrate.During structure construction of tunnel, another key character of this structure is: it may be easy to penetrated by excavator (especially tunnel boring machine) and destroy during building tunnel in construction.It is favourable that this makes the present invention especially throw in vertical shaft for structure temporary tunnel wall and tunnel boring machine.Use the fiber mixed with concrete to make significantly to reduce the quantity of the coupling member for longitudinal member, and do not undermine integrally-built intensity.By reducing the quantity of coupling member, the time be connected to by coupling member needed for longitudinal member also shortens pro rata, thus it is destroyed so it typically is the prime cost of the structure of short-term because being designed to during evacuation works to reduce structure.
When the coupling member used has flexibility, also reduce the cost that there is different geometry (structure for specific plan may customize), such as carrying cost and cost of transportation.
Although principle of the present invention keeps identical, should be understood that, without departing from the scope of the invention, embodiment and structure detail can broadly change for those embodiments describing and explain and structure detail.
