Description
The bearing device of using when the utility model relates to a kind of under ground piping railroad crossing, highway, particularly gas pipeline bearing device.
The gas pipeline laying generally is embedded in underground, when railroad crossing, highway, does not allow maybe can not excavate the open drain pipe laying, when needing from underground passing through, then adopt the jacking construction method, be about to sleeve pipe and head into, pass railway or highway from underground, lay concrete cushion in the sleeve pipe with concrete system, become flat bed course with concrete with the embedded part cast-in-site, treat that flat blinding concrete solidifies after, again gas pipeline is loaded onto the pipe clamp support, push in the concrete sleeve, there is following shortcoming in this method:
1, cast-in-site in the concrete sleeve, operation is difficulty, and particularly the push pipe of longer distance will accomplish that the concrete pipe inner cushion layer is straight, has great difficulty, difficult quality guarantee.
2, the engineering phase longer, the cast-in-place concrete bed course needs through the maintenance solidification process.
3, when the combustion gas caliber big (
More than 500) distance is when longer, and this gas pipeline weight increases, and when gas pipeline was pushed sleeve pipe, support of pipelines increased bed course frictional force, and fragile bed course also easily abrades the anticorrosive coat of gas pipeline.
In order to solve above-mentioned difficulties, the utility model proposes a kind of underground bearing device of gas pipeline for railroad crossing, highway, river etc., this device is simple and easy to do, need not the cast concrete bed course in the sleeve pipe, shorten the construction time, alleviate workload, gas pipeline can push in the sleeve pipe easily, safe and reliable, the anticorrosive coat that guarantees gas pipeline can not sustain damage in construction, adopt this bearing device to carry out crossing construction, its cost with compare with concrete cushion method construction, engineering cost reduces greatly.
The utility model is achieved in that it is by sleeve pipe 1, pipe clamp parts 2 and support unit are formed, the pipe clamp parts 2 that are installed on the gas pipeline outer surface are positioned on the support unit, they all are positioned at sleeve pipe 1, described support unit is by boat-shaped support 3, roll wheel assembly 4 and height adjustment assembly 5 are formed, pipe clamp parts 2 are supported in the below and are equipped with on the boat-shaped support 3 of roll wheel assembly 4, boat-shaped support 3 all links to each other with height adjustment assembly 5 with roll wheel assembly 4, regulate the height of gas pipeline G by height adjustment assembly 5, two sides of boat-shaped support 3 have supporting plate 34, on the inwall that is bearing in sleeve pipe 1, on the roller shaft 44 in the roll wheel assembly 4 roller 43 is housed, the axle head 45 of this roller shaft extend into a left side, right supported plate 41,42 elongated slot 46, in 47, and can in this elongated slot, move up and down, adjusting bolt 51 in the height adjustment assembly 5 is arranged in the corresponding screw of boat-shaped support 3,51 ends, 54 roof pressures of this bolt are on the axle head 45 of roller shaft, should regulate bolt 51 by turn, to regulate this roller shaft 44 on a left side, right supported plate 41,42 elongated slot 46, upper-lower position in 47, thereby the height of adjusting gas pipeline; Or at the axle head 45 of described roller shaft and regulate between the bolt 51 depression bar 53 is housed, by this depression bar 53 of end 54 roof pressures of regulating bolt 51, by depression bar 53 roof pressures on the axle head 45 of two roller shafts; During installation, need not to lay concrete cushion in the sleeve pipe 1, under roller 43 guiding of gas pipeline in roll wheel assembly 4, be pushed at an easy rate in the sleeve pipe 1, to move on roller shaft 44 tunings with regulating bolt 51 then, boat-shaped support 3 is descended, the supporting plate 34 of boat-shaped support two sides is bearing on the inwall of sleeve pipe 1, be about to gas pipeline supporting location.
Adopt this bearing device, import by roller, reduced the sliding friction between support of pipelines and the embedded part widely, not only push easy and unlikely because frictional force is excessive when causing pushing that the anticorrosive coat of gas pipeline outer surface is scratched, guaranteed quality, alleviated heavy manual labor, improved efficiency of construction, in addition, owing to saved concrete cast-in-site operation, saved wide variety of materials, the maintenance solidification process has been accelerated construction speed widely, compare with original concrete cushion method construction, the utlity model has simple in structure, install fast, save investment, the reliable quality advantage.
