Abstract
The invention relates to a method for setting the last hole bridge of tunnel by railway bridging machine, wherein the suspend beam can be folded and rotate, without interfering the tunnel outlet, to mount the front hole bridge beam at the front hole position; and it folds the back leg, front leg, and the auxiliary leg, to meet the size of tunnel, to arrange the whole bridging machine on the beam carrier, to pass the tunnel. The invention can reduce the time and the cost.
Description
Technical field
The present invention relates to the method that a kind of 900t special line for passenger trains bridge formation frame is established last bridge before the tunnel and entered the tunnel.
At present, when setting up last position, hole before setting up the tunnel of machine, there are a lot of difficulty, often adopt the method for bridging to solve,, cause the construction cost height as cast-in-situ concrete beam for passenger dedicated railway line, and problem such as long construction period.And when the tunnel, often dismantle the bridge formation machine on a large scale, transportation is reinstalled again then.When dismounting, must use crane gear, and often because near the restriction in place, the job site tunnel entrance, the problem that can cause crane gear to use, must be by manpower or supporting facility, thereby cause great amount of manpower, the waste of material resources and financial resources has had a strong impact on the normal use of bridge formation machine.
Summary of the invention
The objective of the invention is for addressing the above problem, and provide a kind of railway bridge erecting machine to set up last bridge before the tunnel and advance the method in tunnel.
Method step of the present invention:
A, set up before the tunnel the second last bridge and set up and finish, will descend the nose girder overhead traveling crane to retreat to the semi girder rear portion, folding semi girder control device is installed;
B, start folding semi girder control device, anterior semi girder is returned back to and the hands-off vertical cantilever in tunnel on behind the pin joint;
C, bridge formation machine run to position, last hole, tunnel, and preceding hanging beam overhead traveling crane and auxilliary supporting leg are prepared lifting nose girder down;
The anti-change gear lifting of D, preceding hanging beam overhead traveling crane and auxilliary supporting leg nose girder down is transported in the tunnel, and dismounting is nose girder front and back supporting leg down, and anchoring temporarily;
E, preceding hanging beam overhead traveling crane retreat under the handling supporting leg before and after the nose girder, and Beam transportation vehicle runs to the feeding beam position, the forward and backward hanging beam overhead traveling crane lifting concrete beam beam that puts in place to last hole;
The anti-change gear lifting of F, preceding hanging beam overhead traveling crane and auxilliary supporting leg nose girder down retreats on the last Kong Liang;
G, bridge formation machine retreat to position, second hole, by folding control device semi girder are resetted, and following nose girder overhead traveling crane moves to the semi girder front end;
H, oil cylinder and telescopic are installed on Beam transportation vehicle, jacking bridge formation machine rear portion, the rear support leg lower transverse beam that dismounting has running truck sets up interim leg, makes the rear support leg position become the gate-type structure, withdrawal oil cylinder telescopic;
I, Beam transportation vehicle move forward to bridge formation machine bottom, and oil cylinder and telescopic jacking bridge formation machine are installed thereon, simultaneously, and folding forwards, backwards auxilliary supporting leg and front leg strut;
J, withdrawal jacking cylinder telescopic place on the Beam transportation vehicle bridge formation machine integral body, pack by the Beam transportation vehicle low level and pass through tunnel.
The good effect that method of the present invention had is: when having solved present bridge formation frame and establishing the tunnel, the rear support leg and the semi girder that need integral demounting bridge formation machine, and be difficult to dispose the practical problem of crane facility, the massif that perhaps changes the tunnel entrance place strengthens open cut length, widen that the tunnel face is advanced and abutment between distance; Or cast-in-place beam method.So not only increased the investment of engineering, and increased construction period, the present invention has had simple and efficient realization setting up of last bridge only limits under the situation of partial disassembly, utilizes the special equipment of original bridge formation promptly to finish.Made full use of the function of use of bridge formation machine, in order to reduce construction cost and construction period.
The specific embodiment
Be one to show method of the present invention better, be described in further detail below in conjunction with diagram.
Its method step is:
Fig. 1 after the second last bridge sets up and finishes before tunnel entrance, with descending the nose girder overhead traveling crane to retreat to the root of cantilever, installs bridge formation machine semi girder control device;
Fig. 2 starts the oil cylinder that folds the semi girder control device, and withdrawal oil cylinder pulling support makes leading portion semi girder partly upwards slowly return back to the upright position along the pin joint at this place;
Fig. 3, the complete machine via hole of bridge formation machine puts in place, outstanding straight on the head beam and tunnel are not interfered till;
Fig. 4, by nose girder under preceding hanging beam overhead traveling crane and the anti-change gear lifting of auxilliary supporting leg, and the forward and backward supporting leg of nose girder under the anchoring temporarily, will descend nose girder to be transported in the tunnel, preceding hanging beam overhead traveling crane is return nose girder front and back supporting leg under the handling, prepares to set a roof beam in place;
Fig. 5, the bridge formation machine moves to last position, hole beam that falls by forward and backward hanging beam overhead traveling crane lifting concrete beam and puts in place;
Fig. 6 is worked to cooperate moving to last Kong Liang under the handling behind the nose girder by preceding hanging beam overhead traveling crane and the anti-change gear of auxilliary supporting leg;
Fig. 7, bridge formation machine complete machine retreat to position, second hole, start the revolution of oil cylinder control cantilever and reset, and following nose girder overhead traveling crane moves forward to the semi girder end;
Fig. 8 installs oil cylinder and telescopic, jacking bridge formation machine rear portion on the fortune beam, dismounting has the rear support leg lower transverse beam of running truck, makes the rear support leg top rail folding, and interim leg is installed at its rear support leg top rail position, make rear support leg become the gate-type structure, withdrawal oil cylinder telescopic;
Fig. 9 makes the Beam transportation vehicle reach, and integral body places under the bridge formation machine, and oil cylinder and telescopic jacking bridge formation machine are installed, and removes interim supporting leg, simultaneously, and folding forwards, backwards front leg strut and auxilliary supporting leg;
Figure 10, withdrawal oil cylinder and telescopic place on the Beam transportation vehicle bridge formation machine, pack the bridge formation machine by the Beam transportation vehicle low level and pass through tunnel more conveniently.
In above-mentioned, described folding rear support leg structure is the utility model patent technology that adopts the inventor's the patent No. 200520135638.2.And folding semi girder is that to adopt the patent No. of the present invention be 200520135637.8 utility model patent technology.
