Description
Technical field
The present invention relates to road construction fields, and in particular to a kind of road rain water pipeline construction method.
Background technique
With the rapid development of the national economy, highway, the railway Grade Separation Project in all parts of the country built increases day by day.Road
Draining design is the important link and element of municipal road construction, and Drainage Design is unreasonable, easily causes serious ponding.City
City's rainwater-collecting pipeline construction, the construction quality for considering not only construction are also contemplated that construction speed, how to guarantee construction
In the case where construction quality, construction speed is improved, is always that those skilled in the art need to solve one of direction, existing road
In the storm sewer work progress of road, the operation of down tube and interface is as follows: cooperating artificial down tube using crane.When with crane down tube,
Distance of the crane away from trough rim, tubing storage, traffic route etc. should be determined according to ambient conditions such as groove width depth, soil properties.Pine
Soft ground also needs to be reinforced with lumps of wood place mat, to ensure to park balance.Centering is needed to dial after down tube straight, in crowbar underlay with wood
Plate, can not straight cutting in concrete foundation, to complete under pipes whole between two inspection shafts, checking can interface after the gradient is errorless.It is above-mentioned
Work progress the problem is that: in operating process, need multiple worker's lower grooves to assist crane lowering-in operations, there is only peaces
Full hidden danger, and low efficiency, and tube coupling is easy mutually to collide with the pipeline under slot, causes piping failure.
Summary of the invention
It is an object of the invention to overcome the above deficiencies in the existing technologies, and provide a kind of safety preferably, apply
The higher road rain water pipeline construction method of work efficiency rate.
Technical solution used by the present invention solves the above problems is:
A kind of road rain water pipeline construction method, including following implementation steps:
Measurement of the step 1. according to construction conduit slope and the landform of locality, before carrying out channel excavation；

The bottom of the hydraulic supporting feet 43 offers support leg groove 431, is fixed in support leg groove 431 for connecing
Tread surface bottoms out limit switch 432.
Have on appliance stand 42 for covering on the postposition located space 441 on pipe main body, the postposition from top to down
Positioning mechanism includes pipe 442 on the left of postposition, pipe 443 on the right side of postposition, side pipe 444 and postposition delivery device 462 in postposition, postposition
Left side pipe 442, pipe 443 on the right side of postposition, side pipe 444 is rotatably installed in postposition located space 441 in postposition, pipe on the left of postposition
It is in 40 °~50 ° of angle between the axis of side pipe 444 in 442 axis and postposition, the axis and postposition of pipe 443 on the right side of postposition
It is in 40 °~50 ° of angle between the axis of middle side pipe 444, pipe 442, postposition right side pipe 443 are located in postposition on the left of postposition
The left and right sides of side pipe 444 is fixed with the pipeline limit switch for sense pipeline body outer wall position on appliance stand 42
445.Since pipe main body is tube-shaped structure, thus the outer wall of side pipe 444 is against in left side pipe, postposition right side pipe 443, postposition
It on the outer wall of pipe main body, is managed on the left of the axial line distance of pipe main body, the distance of side pipe 444 is in postposition right side pipe 443, postposition
The radius of pipe main body, thus 42 relative position of axis and appliance stand of pipe main body has been determined.Pipe 442 on the left of postposition, after
Set that right side pipe 443, side pipe 444 is also convenient for realization device bracket 42 using rotational installation and carries out along the axis of pipe main body in postposition
Sliding.
After appliance stand 42 is put down from top to bottom, managed on the left of postposition, side pipe 444 is outer in postposition right side pipe 443, postposition
Wall is against the tube wall of the pipe main body in postposition located space 441, the positioning of the pipe main body of realization device bracket 42 and postposition.
There is the preposition located space 451 for accepting the pipe main body to fall, preposition located space on appliance stand 42

When make the oil outlet for grabbing hydraulic cylinder 3124 and oil inlet be in channel status, while the telescopic rod for unloading hydraulic cylinder 3125 is stretched
Out, so that claw 3122 is pushed out in pipeline, so that completing automatic catching mechanism 31 is detached from pipeline, at this time preposition delivery device
461 lateral push rod 471 is located at the front of the pipeline birdsmouth just fallen.
8) under the driving of the push hydraulic cylinder 472 of preposition delivery device 461, lateral push rod 471 moves a distance
Afterwards, be against on the end face of the pipe main body just fallen, under the promotion of lateral push rod 471, the pipeline just fallen be pushed rearward into,
Until lateral push rod 471 moves to the stroke end of push hydraulic cylinder 472, the pipe main body just fallen at this time and first segment
Pipeline birdsmouth completes docking.
9) under the action of sealer drive motor 488, conduit extension rod 4873 is rotated, and sealer is against two pipelines
Interface, under the action of screw drive motor 4833, conveying screw rod rotation, thus by mortar via flexible delivery pipe 4834
It is pushed into slurry channel, under the action of conduit supporting plate drive motor 486,50 ° of 484 positive and negative rotation of arc-shaped rack (is rotated clockwise
50 °, then rotate counterclockwise 50 °) so that 50 ° of sealer positive and negative rotation (rotate clockwise 50 °, then rotate counterclockwise 50 °), from
And by two sealers squeeze out mortar can fill entire interface, hereafter sealer not squeeze mortar in the case where, then
50 ° of positive and negative rotation (rotates clockwise 50 °, then rotates counterclockwise 50 °), so that the mortar covering of interface is more uniform.
10) preposition left side pipe 453, preposition right side pipe 454 fold outward under the action of side pipe hydraulic cylinder 4574, avoid
Interference is generated in preposition left side pipe 453, preposition 454 motion process of right side pipe with the outer wall of pipeline, positioning is sling in positioning driving 41
Pipelayer attachment 4 to initial, set position, the hydraulic supporting feet 43 of 42 two sides of appliance stand rises,
