Description
Technical field
The invention belongs to carry out a kind of method that concrete rack construction is used in ultra-deep waters, particularly in ultra-deep waters
A kind of method constructed using the pile foundation of completion to support cushion cap set in pile foundation.
Background technology
At present, ultra-deep waters carry out concrete support construction, the method used be set up large area under water, work waterborne
Industry platform support lifts up into row operation using argosy, and extensive work amount is brought to construction, while setting up the expense of platform generation
With very high, construction costs is added.
The content of the invention
The purpose of the present invention is held aiming at the disadvantages mentioned above that prior art is present there is provided a kind of ultra-deep waters aquatic pile foundation
Platform construction method, simple and effective can carry out cushion cap model sheetinstallat waterborne, concrete placings etc..
The object of the present invention is achieved like this：A kind of ultra-deep waters aquatic pile foundation construction method, including drilling are filled
Note stake stake, square steel, H profile steel, template composition.On the water during rack construction, the construction of cast-in-situ bored pile is first carried out, in perfusion
Pile driving construction to design drawing require when, all drill-pouring stake tops set a square steel, square steel be located at cast-in-situ bored pile reinforcing bar seam
In the middle of gap, square steel is in horizontal positioned, and square steel length is the diameter length of cast-in-situ bored pile.H profile steel, H profile steel are placed in square steel
Through square steel, every H profile steel length is 1.5 times of support cushion cap length.The H profile steel passed through at the top of every cast-in-situ bored pile is formed
One section of crossbeam, several cast-in-situ bored pile shape crossbeams in a row, sets up the longeron perpendicular to crossbeam, the quantity of longeron on crossbeam
Customized by specific requirement, longeron length is 1.5 times of support cushion cap length.Support cushion cap template is laid on longeron, simultaneously
Take reinforcement measure.After the completion of cushion cap template construct is reinforced, you can carry out the colligation of cushion cap reinforcing bar and concrete placings.Treat that concrete support is completed
Afterwards, template is removed, cleared up.Longeron, the H profile steel crossbeam being placed in square steel are extracted out simultaneously.The H profile steel of extraction can be
It is continuing with next time in boat support frame bearing platform construction.
Beneficial effect of the present invention；Compared with prior art, a kind of ultra-deep waters aquatic pile foundation cushion cap that the present invention is provided is applied
Work method, need not set up on platform base, using the cast-in-situ bored pile constructed, is being added on cast-in-situ bored pile in addition
Square steel and H profile steel, facilitate setting up and constructing for cushion cap template, while being offered convenience to follow-up reinforcing bar colligation and concrete placings.
Brief description of the drawings
Accompanying drawing is used for providing a further understanding of the present invention, and constitutes a part for specification, the reality with the present invention
Applying example is used to explain the present invention together, is not construed as limiting the invention.In the accompanying drawings：
Fig. 1 is a kind of ultra-deep waters aquatic pile foundation construction method schematic diagram proposed by the invention；
In figure：1st, cast-in-situ bored pile；2nd, square steel；3rd, H profile steel；4th, template.
Embodiment
The preferred embodiments of the present invention are illustrated below in conjunction with accompanying drawing, it will be appreciated that preferred reality described herein
Apply example to be merely to illustrate and explain the present invention, be not intended to limit the present invention.
Embodiment 1
