Abstract
The invention discloses a suspension type single track traffic seamless route based on assembly technology. The technology is characterized in that the prefabricated assembly suspension type single track traffic seamless rail bridge, through the arrangement of a pass-through track beam top portion external prestressing tendon N1, a track beam middle body external prestressing tendon N2, track beam bottom portion external prestressing tendon N3, is connected with an k truss prefabricated assembly suspension type single track traffic track beam 1 suspended below a pier capping beam 2, a seamless route of k-span one-link suspension type single track traffic continuous system is formed. The suspension type single track traffic seamless route based on assembly technology achieves the effect that through watering seams in the field and the establishment of the pass-through external prestressing tendon, the prefabricated assembly suspension single track traffic track beam bridge simply-supported system is changed into the k-span one cross continuous system seamless route, the track beam seam is reduced, the driving speed and smoothness of vehicles are increased, and therefore the purpose of increasing transportation quantity can be achieved.
Description
Technical field
The present invention relates to suspension type monorail field of traffic, is applied to the seamless process of suspension type monorail traffic track beam, specifically
Ground says be based on assembled technology suspension type monorail traffic seamless process circuit implementation method, can be applicable to be based on assembled skill
The construction of the suspension type monorail traffic seamless process circuit of art.
Background technology
Suspension type monorail traffic system has compared to straddle-type monorail transportation system not to be affected by sleet, radius of turn more
The lower advantage of little, construction cost, is the important development direction of future city monorail traffic system.Compare straddle-type monorail friendship
Logical, in addition to above-mentioned advantage, the track girder of traditional steel construction there is also many weak points, such as suspension type monorail traffic
Noise is larger, driving ride comfort is poor so that train running speed is only capable of reaching 50km/h, and general 2 section 1 of marshalling quantity is compiled
Group, thus its freight volume only has 1/3 of cross-saddle single-track traffic or so, it is difficult to meet domestic communication demand.The suspension that bottom is remained silent
Formula track girder compensate for that bottom opening steel construction track girder noise is big, the defect that rigidity is little, but the suspension type monorail of system of simple supporting
Traffic track Liang Liang seams are more, also have impact on road speed and ride comfort.If the quantity of beam seam can be reduced, just can further improve
The speed of service and ride comfort of the train on suspension type monorail traffic route, is further able to improve passenger capacity, meets traffic need
Ask.Therefore, fabricated design concept need to be based on, that develops suspension type monorail traffic seamless process circuit realizes technology.
The content of the invention
The technical problem to be solved is：For prefabricated assembled suspension type monorail traffic track beam freely-supported body
Binder stitches more shortcoming, using the technical method of Simply supported non-uniform, by arranging prestressed strand, by the prefabricated of system of simple supporting
Fabricated suspension type monorail traffic track beam is changed into the continuous system of multispan one, reduces track girder beam seam, increases driving
Travel speed and ride comfort, with this purpose of increase capacity is realized.
The technical solution adopted for the present invention to solve the technical problems is：
Suspension type monorail traffic seamless process circuit based on assembled technology, it is characterised in that：This is prefabricated assembled outstanding
Hanging monorail transit seamless process guideway beam is by arranging elongated track girder top external prestressing steels N1, track girder middle part body
External prestressed muscle N2, track girder bottom external prestressing steels N3, the k Pin hung on below pier cap beam 2 is prefabricated assembled
Suspension type monorail traffic track beam 1 is coupled together, formed k across one suspension type monorail traffic continuous system seamless process line
Road.
Based on the suspension type monorail traffic seamless process circuit of assembled technology, the implementation method of described seamless process circuit,
It is characterized in that：Prefabricated assembled suspension type monorail traffic track beam 1, by bearing Z1 be installed in pier cap beam 2 it
Under, form prefabricated assembled suspension type monorail traffic track beam system of simple supporting；Wet connecing is being poured in one between k Pin track girders
Seam JF, treats that it is reached at the top of the elongated track girder in of design strength post-stretching in the middle part of external prestressing steels N1, track girder
External prestressing steels N2, track girder bottom external prestressing steels N3, hand over the prefabricated assembled suspension type monorails of the k Pin in
Logical track girder 1 links together, and forms seamless process circuit.
Based on the suspension type monorail traffic seamless process circuit of assembled technology, described prefabricated assembled suspension type monorail
Length L=n of traffic track beam 1 × 10M；Wherein, M=100mm, n=10~40, Pin numbers k=1~5 of each track girder.
The invention has the beneficial effects as follows：
By cast-in-place wet seam, elongated external prestressing steels are set, by prefabricated assembled suspension type monorail traffic rail
Road beam bridge system of simple supporting is changed into the continuous system of multispan one, reduces track girder beam seam quantity, increase driving travel speed and
Ride comfort, with this purpose of increase capacity is realized.
