Specific implementation mode
Attached drawing 1 is please referred to, the figure shows a kind of precast beam place horizontal layouts provided by the embodiments of the present application.
Bridgehead by Blastig or bridge tail roadbed in bridge location area is arranged in a kind of precast beam place, precast beam place；Including：From separate
Bridge location area to close to bridge location area and set gradually along bridge formation direction reinforcing bar storage area 1, predefined region 2, beam strorage area 3, Bridge Erector peace
Area 4 is filled, further includes A-road 5, gantry crane 6, wherein A-road 5 passes through reinforcing bar storage area 1, predefined region 2 along bridge formation direction；Gantry
It hangs 6 to travel along gantry rail 9, gantry rail 9 is arranged along bridge formation direction；Bridge Erector installing zone 4 is arranged in beam strorage area 3 and bridge location area
Between.
In the embodiment of the present application, the Bridgehead by Blastig or bridge tail roadbed in bridge location area is arranged in precast beam place, is mainly examined
The factor of several aspects is considered：
(1) Bridgehead by Blastig and bridge tail roadbed can be fully met pre- on the basis of the main line roadbed of bridge location area both sides
The storage of beam processed and the requirement of working space.(2) can meet transporting equipment different type and the environment in size and place,
Geological conditions reduces volume of earthwork and foundation engineering amount.(3) Economization on land improves the utilization rate of land resource, reduces soil
Ground takes over for use and expense of reclaiming, and reduces prefabricated cost.(4) it fully considers communications and transportation factor, is connected with existing highway, with bridge location area
Distance recently, the transport of convenient material and tool utmostly shortens transportation range, ensure that transporting precast beams safety and
Construction speed.
On the precast beam place, reinforcing bar storage area 1 is disposed furthest from the position in bridge location area, can avoid gantry crane 6
When current in reinforcing bar storage area 1, cause casualties accident.
Predefined region 2 includes a plurality of types of precast beams, in Fig. 1, from separate bridge location in close to bridge location area successively cloth
Set the beam prefabricated areas T, prefabricated box -beam area, plate-girder predefined region, three kinds of different patterns in corresponding diagram.For making not in predefined region 2
On the one hand the beam of same type will consider the making convenience of precast beam in predefined region 2, on the other hand also to consider follow-up
The exploitativeness of transport.
For storing precast beam, close to bridge location area, setting shortens transportation range, ensures construction speed for beam strorage area 3.
Bridge Erector installing zone 4 is arranged between beam strorage area 3 and bridge location area, facilitates and hangs the transporting precast beams in beam strorage area 3
It is filled to job location.
A-road 5 for transport vehicles travel, during making precast beam, need conveying cement, reinforcing bar, steel plate,
Lumps of wood and other items, by transport trolley by goods transportation to designated position.
Gantry crane 6 is used for lifting, the transport etc. of goods and materials in precast beam manufacturing process.Gantry crane 6 is in 9 uplink of gantry rail
It sails, wherein the cross-sectional area of gantry rail is as shown in Fig. 2, in figure, superposed protrusion is to be connect with 6 main body of gantry crane
Track, gantry rail 9 is formed by concreting, based on compression, to prevent concrete cracking in work progress, can suitably be increased
Add reinforced mesh and construction muscle, such as increases by 16 reinforcing bars of φ and 10 stirrups of φ, concrete cracking can be effectively prevent.
Gantry crane 6 generally selects two kinds of specifications, wherein big load-bearing gantry crane generally selects two pairs, small load-bearing gantry crane to select
One secondary or two pairs, handling of the big load-bearing gantry crane for precast beam are respectively arranged with lifting rope at the both ends of precast beam, with two secondary big load-bearing
Gantry crane realizes the handling of precast beam；Small load-bearing gantry crane is mainly used for the handling of the materials such as reinforcing bar, template, is required according to weighing
Select a secondary or two secondary gantry cranes.For example, selecting the secondary handling precast beam of 100t gantry cranes two, two secondary 5t gantry cranes or a pair are selected
10t gantry crane handlings reinforcing bar, template etc..
It should be noted that gantry rail 9 along bridge formation direction there are head fall, the designed lines longitudinal slope of main line is generally
2%, general control is within 1%~1.5%, to meet wanting for operation of the gantry crane 6 during handling, stress etc.
It asks, head fall can be by carrying out excavation or embankment construction realization to basic roadbed.
In addition, when be the landform that need to be turned for basic roadbed, precast beam place uses more broken line set-up modes, straightway and
The spaced setting of curved section, ensures that turning radius is at least 900m~1000m, at this point, gantry rail 9 is using same setting
Mode, in order to meet gantry crane 6 in turning position synchronous walking, the setting change quick-mounting at outboard end gantry leg location of turning
It sets, is adjusted by inside and outside speed change, to realize the interior outside synchronous walking of gantry crane 6.
Bridge Erector installing zone 4 is used for the installation of Bridge Erector, and handling, the installation of first bridge.By land-service road, can arrive
Up to Bridge Erector installing zone 4, when such as land-service road inconvenience, also A-road 5 can be extended to Bridge Erector installation along beam strorage area 3
Area 4 will fully consider the reasonable Arrangement of each region in the process.
The width of integral subgrade is generally 24m~25m, and the width of setting A-road 5 is 4m, and the beam prefabricated areas T, box beam are pre-
Area processed, plate-girder make area and are arranged from the distant to the near along bridge formation direction, and beam strorage area 3 is divided into box beam along bridge formation direction and deposits from the distant to the near
Area, T beams storage area, plate-girder storage area are put, each subregion reserves construction and transport space.Gantry crane 6 uses 100t and 5t
Two kinds of specifications of gantry crane each two are secondary, in precast beam manufacturing process, are mutually independent of each other, and respectively construct, and improve working efficiency, accelerate
Construction speed.
It should be noted that the placement order of precast beam does not limit in predefined region 2 and beam strorage area 3, according to practice of construction
Depending on situation.
A kind of precast beam place provided by the embodiments of the present application, include the reinforcing bar storage area 1 being sequentially arranged along bridge formation direction,
Predefined region 2, beam strorage area 3, Bridge Erector installing zone 4 and A-road 5, gantry crane 6 etc., reinforcing bar storage area 1 is for storing former material
Material；Predefined region 2 is for making precast beam；Beam strorage area 3 is for storing the precast beam ready for use that completes；Bridge Erector installing zone 4
Handling, installation for the installation of Bridge Erector, and first bridge；A-road 5 passes through for construction machinery；Gantry crane 6 is for pre-
The transport of materials such as beam processed, reinforcing bar, template.End of the bridge or bridge tail roadbed in bridge location area is arranged in precast beam place by the embodiment of the present application
On, the difficulty of the precast beam Site Selection caused by landform limitation or land status are not inconsistent is avoided, while avoiding requisition
It ploughs and reclaims expense, saved cost, reasonable Arrangement precast beam place, mould when fully considering width of subgrade, precast beam construction
The peace of plate tears the factors such as space and beam transporting passage, haulage vehicle passage open, improves working efficiency, reduces casualties risk, reduces
