Description
Technical field
The present invention relates to the realm of building construction more particularly to a kind of construction methods of plank road structure waterborne.
Background technique
Existing plank road structure waterborne uses integral cast-in-situ structure, as shown in Figure 1,11 top casting concrete base of friction pile
Concrete column 13 is set on plinth plate 12, concrete base slab 12, is arranged on concrete column 13 and combines distribution beam in length and breadth, it is described in length and breadth
Combining distribution beam is to combine beams of concrete 2 ' in length and breadth, combines concrete slab is arranged on beams of concrete 2 ' in length and breadth.
On the one hand, since concrete column is arranged on construction concrete base slab, concrete base slab, a large amount of reinforcing bars is needed to tie up
The processes such as bundle, template installation, concreting, need a large amount of human and material resources, and concrete base slab and concrete column need to carry out
It conserves within 28 days, the duration is very long.
On the other hand, since concrete base slab and concrete column are located at river surface hereinafter, therefore, concrete foundation of constructing
The cofferdam 600m long need to be set when plate and concrete column, dredging of drawing water, time-consuming takes a lot of work, is seriously polluted, and cofferdam has one in water
Fixed risk.If cost is high, long construction period using steel sheet-pile cofferdam is used.If doing cofferdam using double-row steel pipe stake,
Although low cost, bankets and be easy to pollute river.The safety for paying attention to cofferdam at any time is needed during cofferdam construction simultaneously, is kept away
Exempt from cofferdam leak, and need to preventing cofferdam collapsing from doing emergency measure, safety is poor.Construction cofferdam about 12 days, work is elongated
Phase.
Therefore, how providing one kind can accelerate construction progress, moderate cost, while can be to avoid cofferdam construction to river
Pollution plank road structure waterborne construction method, it has also become construction circle need further improvement and optimization the technical issues of.
Summary of the invention
