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:
