Description
Technical field
The present invention relates to field of bridge construction, be specifically related to a kind of construction method of trestle waterborne.
Background technology
Along with Chinese large-sized on-water bridge build growing, trestle waterborne construction also gets more and more.Existing trestle construction waterborne adopts halieutics and crane barge construction method usually.
During halieutics construction, the first hole of first construction bridge, then to be constructed basis, next hole and trestle work structure by packaged type full circle swinging loop wheel machine.
In crane barge method work progress, first prepare large-scale floating crane and barge, then other construction equipments are positioned on barge, realize trestle construction by the operation of large-scale floating crane.
There is following defect in existing trestle construction method waterborne:
(1) environment of over-water construction is poor, the situation that the stream that there will be that the wave is high is anxious, and now, adopt halieutics construction, trestle steel pipe pile is accurately located the larger operation easier of existence by packaged type full circle swinging loop wheel machine by staff; When adopting the construction of crane barge method, crane barge and barge are difficult to stable placement, and staff is difficult to trestle steel pipe pile accurately to be located, easily there is relatively large deviation in trestle steel pipe pile location, and need trestle steel pipe pile is pulled up and reorientates, extend the duration of trestle construction, add construction cost.
(2) halieutics construction is carried out mainly through crawler type loop wheel machine, and the cantilever of crawler type loop wheel machine is shorter, and its construction distance is shorter, has been difficult to large span trestle construction waterborne.
Summary of the invention
For the defect existed in prior art, the object of the present invention is to provide a kind of construction method of trestle waterborne, the duration of construction can be shortened, reduce construction cost, complete the construction of large span trestle waterborne.
For reaching above object, the technical scheme that the present invention takes is: a kind of construction method of trestle waterborne, comprises the following steps:
