Description
Technical field
Track construction servicing unit is the utility model is related to, solid concrete roabed cast-in-place construction is used in specially a kind of subway tunnel
Rail-mounted concrete pump pipe carrier.
Background technology
Subway has turned into the important means of conveyance in city, and at present, Subway Tunnel is tunneled using shield machine more, synchronous peace
Fill arc section of jurisdiction and form circular cross section separate tunnel.Narrow space in separate type subway tunnel, construction logistics condition are very tired
Difficulty, cast-in-place solid concrete roabed prior art are constructed to be pusher, i.e., since in station the propelling construction into tunnel paragraph by paragraph, until entering
Enter next station, be specially：The section of track is assembled, utilizes rail-mounted transport vehicle（Walking is on the track for just pouring completion）By the section of track
Front laying point is pushed to forward, uses small-sized unit of laying a railway track successively（Two linkage small-sized straddle trucks）Aid in section of track handling and just
Position, binding structure reinforcing bar, adjusting means is coordinated to carry out section of track locus adjustment using accurate measurement means, it is mixed using long range
Solidifying soil pumping（Or hopper）Technique pours railway roadbed concrete, and welding rail gap forms gapless track.
The greatest drawback of this construction method is that logistics vehicles must walk to be poured on shaping railway roadbed track new,《Specification》
Regulation before concrete strength is not up to more than the 70% of design strength must not bearing load effect, newly poured for that purpose it is necessary to wait
Build railway roadbed concrete strength satisfaction《Specification》Requesting party can arrange rail row transport, have a strong impact on construction speed；When the duration is urgent,
Railway roadbed concrete strength is often forced in not yet to reach《Specification》Bearing load before it is required that, railway roadbed concrete cracking seriously be present
Hidden danger of quality, therefore transport weight of material every time and need to strictly be limited, cause that risk is big, work efficiency is low, cost is high.
Monolithic roadbed track category longitudinal strip structure, cast-in-place concrete solid concrete roabed use pumped concrete earth process more,
Openr construction site is mostly using horizontal pumping or suspension bucket material-uploading style, but in the tunnel of narrow space or subway, only
Distance can often be pumped up to hundreds of meters using longitudinal direction pumping material-uploading style.Before each pump concrete, low-grade cement must be first used
Mortar carries out pipeline moistening, is hindered to remove to clean ponding in pipeline while examine pipeline sealing and reduce pipeline mill, when
Mortar is considerable when pipeline is longer, and waste disposal can only be used as by moistening the mortar after pipe；After the pump concrete end of job, also need
Pump line is cleaned with water, the sewage after cleaning need to focus on；Once generating pump blockage in operation is, it is necessary to thoroughly remove in pipe
All concrete, the Concrete contamination scene cleared out, and job site need to be thoroughly cleared out before its solidification；Due to pumping distance
Long, profit pipe, plugging, to wash pipe amount of pollutant big, in addition construction site narrow space, and pollutant is cleared up and is inconvenient, or even is caused
The hardening of discarded concrete, increases the amount of labour used and construction cost.
The content of the invention
The utility model in order to solve solid concrete roabed in existing subway tunnel it is cast-in-place when exist because concrete pumping is apart from mistake
Plugging occurs in long and work progress and pollutes the problem of being difficult to cleaning, there is provided solid concrete roabed is cast-in-place in a kind of subway tunnel
The rail-mounted concrete pump pipe carrier of construction.
The utility model is achieved by the following technical solution：Solid concrete roabed cast-in-place construction rail in a kind of subway tunnel
Line concrete pump pipe carrier, it is made up of several pump pipe bracket bodies, pump pipe bracket body includes vehicle frame, vehicle frame bottom
The left and right sides be provided with the wheel carrier of left and right distribution, wheel carrier is connected with rail wheel by wheel shaft, and the left and right ends of vehicle frame are all provided with
Bail is equipped with, bail is connected with draw bar, and draws ring-side wall and be screwed with the puller bolt contacted with draw bar, vehicle frame top
The left and right sides be provided with the positioning square tube of front and rear distribution, position and supporting leg be plugged with square tube, the connection of supporting leg top
There is semicircle arcuation supporting plate, the front and rear sides of semicircle arcuation supporting plate are provided with puller bolt, the tail of semicircle arcuation supporting plate
Arc distributor chute is provided with below portion, the rotating shaft fixed with semicircle arcuation supporting plate is provided with arc distributor chute.
During construction, to concrete transportation and Operation Van's marshalling can be poured, concrete pump is set on flat car, utilizes power supply
As power, on road with putting some concrete hoppers on dressing plate car, with draw bar by some pump pipe bracket body roots
It is integral according to concrete road bed one-time-concreting length connection, concrete pump pipe then is installed in semicircle arcuation supporting plate, mixed
Coagulating the pump pipe union of native pump line all should be arranged on outside pump pipe bracket body in order to connect and dismantle.Using locomotive by pump line support
Frame body pushes to railway roadbed and pours setting so that traction locomotive and the flat car for carrying concrete hopper and concrete pump are equal
It is parked in and pours on track beyond operation area, proceeds by and pour operation, in casting process, locomotive traction working train batch (-type)
It is mobile（One sleepers spacing of advance every time）, by manual control arc distributor chute, concrete enters the railway roadbed road heart and rail
In the sleeper gap of both sides, the purpose accurately poured to railway roadbed is realized.
Before concreting operation, concrete pump pipe interior AT STATION should carry out leak check and pump line moistening in advance,
To ensure pump concrete normal operation, profit pipe mortar, which should be deposited on platform, to be focused on, after the completion of pouring operation, Operation Van
Group returns to station and cleaned, and when plugging occurring in operation process, Operation Van's group returns is cleared up in station.Overcome existing
Exist when solid concrete roabed is cast-in-place in subway tunnel and polluted because plugging occurs in long and work progress for concrete pumping
The problem of being difficult to cleaning.
Some adjustment holes being mutually matched are provided with positioning square tube and supporting leg, latch, arc are provided with adjustment hole
The front and rear sides of distributor chute are provided with handle.
It can be achieved to fix in semicircle arcuation supporting plate by the way that the adjustment hole for positioning square tube and supporting leg is mutually matched into connection
Pump line according to be actually needed carry out up and down adjust, be advantageous to pouring construction.
The utility model is simple in construction, reasonable in design, due to laying waste road in advance, can increase the freight volume of each section of track, greatly
Width improves section of track laying efficiency；Transport load does not enter in railway roadbed pouring molding region, and the too early bearing load of railway roadbed can be avoided to make
With railway roadbed crack is induced, concrete pump is placed in working train front portion, shortens and pump distance, reduces pump tube length input, profit pipe, blocks up
Waste caused by pipe；Concreting operation is carried out using dinkey traction pump line movement, concrete can accurately enter mould, reduce
Artificial refining workload；Hopper, concrete pump, pump line etc. are interior AT STATION to concentrate cleaning, is easy to wastewater reuse approach, reduces in hole
Pollution, improve environment in hole；The utility model has the characteristics that to improve work efficiency, reduces construction cost, in subway tunnel and city
Solid concrete roabed concrete pouring construction occasion in the narrow working spaces such as the long bridge of light rail, there is wide popularizing application prospect.
