Description
Technical field
The present invention relates to monorail train technical field, be specifically related to the pre-pile anchoring mounting structure of a kind of modified model overhead suspension drop in beam.
Background technology
The aerial electric car train that namely aloft track runs below in a hanging manner.This train occurs in Germany the earliest, puts into commercial operation.Comparing with subway and light rail, it is low that hanging type aerial train has cost, security reliability high.2011, the manufacturing technology of this type train introduced China, ends 2012, and the localization rate of parts and components has reached 90%.Estimate to put into effect in 2014 domestic first batch of hanging type aerial train in the city such as Shanghai, Wenzhou.
Article 1, the empty gauge lines put into effect 1984 is open-minded at Dortmund, Germany, phase overall length 1.05 km, connects the Liang Ge school district, north and south of Univ Dortmund, cost 24,000,000 mark at that time.By 2003, putting into operation in local total two lines road, total length is 3.162 kms.Under the control of the computer, the positioning precision of train in/out station can reach within 3 centimetres.
Monorail train adopts 2 joints or 4 joint compartment marshallings, focuses on the transport need of medium-heavy road traffic.Together with passenger interior, empty row are joint compartment limit for tonnage 13 tons often, at most transport passenger 75 person-times.If calculated by 4 joint marshallings, one way seating capacity is 300 people.Train desin speed is 50 kilometers per hour.The speed calculation of 40 kilometers on an hourly basis, adopts 90 seconds normal departure intervals, and carrying capacity reaches 12000 person-times per hour." Li You seat, compartment, also has space to stand, and we arrange the maximum carrying capacity of single line can reach 15000 person-times, the passenger flow situation according to Shanghai, takes 4 joint marshallings the most suitable, and compartment two-wire capable of circulation comes and goes, and operational efficiency is significantly high." Chen Changgui says.According to upper air-sea row railway technology company limited project expert introduction, the feature of monorail train is low energy consumption, medium-heavy road traffic, for Shanghai, is relatively suitable for suburb new city and special transport interconnection, considering the sightseeing function of empty row, offering Binjiang line is also good selection.
Additionally, come and go the monorail train between airport building, railway station, coach station or between transport hub and large-scale theme park, a large amount of precedent is also had to follow.Actual demand according to different cities development, empty row will make up the blank of medium-heavy road traffic traffic from transport and two aspects of going sightseeing.When referring to efficiency and the cost of monorail train, Chen Changgui tells reporter, generally often saves subway carriage every kilometer power consumption 5 to 6 kilowatt hour, and monorail train every kilometer is power consumption 2.4 kilowatt hour only, is equivalent to the half only having the former.From cost, comprising train, track, platform and whistle control system, monorail train every kilometer engineering total price is at 1.2 hundred million yuan-1.5 hundred million yuan, roughly the same with ground tramcar, is about the 1/5 of subway cost, light rail, low speed magnetic floating 1/2 to 1/3.
But, current monorail train foundation pile major part is reinforced concrete structure, this structure is all rigid member, and its pliability is poor, for the span position more than 50 meters, current foundation pile structure can not complete overlap joint task, in order to realize large span, current scheme is the physical dimension by increasing foundation pile, in order to obtain bigger holding capacity, causing a lot of redundancy construction, the cost of foundation pile is greatly increased.
Summary of the invention
It is an object of the invention to provide the pre-pile anchoring mounting structure of a kind of modified model overhead suspension drop in beam, solve that current foundation pile holding capacity is limited, poor toughness, problem that large span position is difficult in adapt to.
The present invention is achieved through the following technical solutions:
A kind of pre-pile anchoring mounting structure of modified model overhead suspension drop in beam, including multiple caissons, caisson is built foundation platform and forms integrative-structure, foundation platform is provided with main supporting rod, main supporting rod is symmetrically arranged with cantilever outwardly, end at cantilever is provided with track girder, and described cantilever is reclinate arcuate structure, and the middle part of two cantilevers is additionally provided with a drawknot arm.nullThe present invention adopts foundation platform as the basis of whole foundation pile，Foundation platform builds formation entirety in caisson，The structure that the interspersed formation of caisson comparatively consolidates，The Superimposed fastener when building foundation platform，Main supporting rod is fixed on foundation platform by connector，Main supporting rod is steel construction，Its both sides decibel arranges cantilever，Symmetrically arranged cantilever makes foundation pile stress comparatively uniform，The cantilever that have employed arcuate structure of present invention innovation，The middle part of cantilever projects upwards、Two ends form downwards warp architecture，The problem overcoming poor toughness，Utilize the elasticity of warp architecture，Add the toughness of cantilever，Connected by the drawknot arm of a warp architecture between two cantilevers simultaneously，The stay cord bearing capacity making two cantilevers is greatly improved，The bearing capacity of section time can be provided by elastic force，When keeping size constancy，Substantially increase bearing capacity，Track girder for large span that is 50 to 80 meter span provides strong support.
The two ends of described drawknot arm are bent downwardly, middle part projects upwards formation warp architecture.In like manner, by adopting the drawknot arm of warp architecture, it is possible to increase the bearing capacity of cantilever further.
Lateral symmetry at described main supporting rod is provided with the hound along track girder directional spreding.By increasing hound, it is possible to support the carrying that span is bigger, further improve bearing capacity.
Described hound one end is connected by connector and the built-in fitting on foundation platform are fixing, and the other end is fixed on main supporting rod by slide mechanism.The main supporting rod of the present invention and hound are all steel constructions, load is increased as when arranging poor process suddenly, its toughness can produce certain deformation, in the bigger region of the temperature difference and practice, expanding with heat and contract with cold of steel construction also results in part deformation, in order to keep good bearing capacity, avoids the stress within steel construction again, this practicality is by adopting slide mechanism as the connection member between hound and main supporting rod, it is possible to overcome relative displacement and internal stress.
Described slide mechanism includes one and is provided with a slide block that can move up and down in chute in chute along the axially arranged chute of main supporting rod, and described hound is connected on slide block.Specifically, chute is vertically arranged on main supporting rod, wherein there is a slide block, slide block can slide up and down in chute, but it is limited to chute, it can not depart from chute, one end of hound is connected by connector and the built-in fitting on foundation platform are fixing, the other end is hinged on slide block, when the side of main supporting rod receives unexpected external force, small deformation can be overcome by the slip of slide block, in time expanding with heat and contract with cold, the slip of slide block also overcomes different expansion rate, the relative movement that amount of contraction is brought, overcome its internal stress, improve tolerance and the service life of entirety.
The middle part of described hound is bent downwardly to form warp architecture.
The present invention compared with prior art, has such advantages as and beneficial effect:
