Description
Technical field
The present invention relates to pile base construction method technical fields, apply in particular to a kind of pile foundation using stake top mobile platform
Work method.
Background technique
Yellow Sea Bridge two bridge in PORT OF NANTONG Yangkou Harbor is adjacent with one bridge of Yellow Sea Bridge, connects the port Yang Kou facing-port industry Qu Yuyang
Mouth port sunlight island.Two bridge overall length 10035m, the pile foundation of bridge are drill-pouring pilework, full-bridge cast-in-situ bored pile totally 810.
Traditional Bridge Pile Foundation Construction is first to set up trestle, then sets up drilling platform in pier location and is connected with trestle, then is being drilled
It constructs on platform pile foundation.Since pile foundation quantity is big, cause the interim steel construction dosage for setting up drilling platform very big, the later period removes
The project amount of platform is also big, considerably increases construction cost and the construction period of pile foundation.
There is the China of entitled " a kind of mobile piling platform of stake top support walking " of Patent No. " CN105421454B "
Patent of invention, the patent describe a kind of piling mobile platform, the steel-pipe pile which is completed using inserting piling is as carrying
Basis carries out pile foundation construction, and this operation platform does not need substantially to carry out auxiliary pile, can save a large amount of steel and construction
Time.But this structure can in practice be only used for the construction site for being capable of forming multiple rows of piling strtucture, the i.e. steel pipe of inserting piling completion
Stake can support operation platform, and otherwise operation platform cannot be installed, therefore be directed to piling strtucture and cannot form operation platform
The occasion on basis is carried, this operation platform can not be competent at.

The method for further building carrying platform in auxiliary stake top are as follows: build more in auxiliary stake top and applied along pile foundation
The stringer of work direction arrangement, installs crossbeam between adjacent stringer, panel-shaped is laid on crossbeam and stringer into carrying platform,
Steel pile casting leading truck and auxiliary pile leading truck are installed on carrying platform.
The method of stringer is further built on auxiliary pile are as follows: distribution beam is being built in the auxiliary stake top with row,
The vertically support of support stringer is installed in distribution beam and can vertically jack the mobile jacking cylinder of stringer, stringer is shelved on
On the slide plate of support upper end.
The method that further pushing tow carrying platform advances along pile foundation construction direction are as follows: by what is arranged along pile foundation construction direction
Pipe bending cylinder one end is fixed, and the other end is connect with the guide rail of stringer lower end on the support, drives stringer in cunning by pipe bending cylinder
It is moved on plate along pile foundation construction direction.
The method that further pipe bending cylinder is connect with guide rail are as follows: install connection far from one end of support in pipe bending cylinder
Seat, is connect by the bolt being arranged on attachment base with the guide rail for offering multiple through-holes, the position of regulating pin and corresponding through-hole
Set the relative positional relationship for changing pipe bending cylinder and stringer.
The method for further being extracted auxiliary pile based on carrying platform are as follows: the auxiliary pile that will be exposed based on carrying platform
Distribution beam, support, jacking cylinder and pipe bending cylinder at stake top remove, then by the equipment on carrying platform by this part
Auxiliary pile is extracted.
Carrying platform is supported on auxiliary pile by the present invention, carrying platform front end carry out the construction of auxiliary pile inserting piling, rear end into
Row auxiliary pile extracts construction, and auxiliary pile is recycled, considerably reduces coming into operation for auxiliary pile, save material.
It is fast on auxiliary pile to be easily carried platform by the way that thrustor is arranged between auxiliary pile and carrying platform by the present invention
Speed is advanced, and is reduced the difficulty of entire pile foundation construction, is improved the efficiency of pile foundation construction.
