Description
Technical field
The present invention relates to bridge construction technical field, more particularly to a kind of pier hangs bottom technique.
Background technology
As economic continues to develop, some roads receive rail friendship, highway, river course etc. and deaden what is do not connected between city
Situation has greatly improvement, and the construction progress of different types of rridges is also gradually being accelerated, still, the pier construction technology of existing bridge
Also there are problems, pier is constructed especially in water, land, pile foundation anchor ear supporting methods and steel jacket box are generally banketed into using cofferdam
The forms such as cofferdam method, wherein, banketed into double more than the 12m Larsens steel sheet piles of Lu Caiyong in cofferdam, and clay shape is filled out in double sheet pile
Into cofferdam, land construction is formed using plain earthen backfill after the shaping of cofferdam.Backfilling of earthwork and cleaning are to river course environment in work progress
Influence is larger, and cofferdam measure cost cost is high；Pile foundation anchor ear supporting methods are to use certain thickness outside the pile foundation completed using construction
Circular steel plate hoop on pier stud, using a kind of construction method of the frictional resistance by the corbels support pier support on steel plate hoop,
But drilled pile hits the regular voucher of Hold Hoop method lactation prefabricated pile or column body, frictional force is difficult to control, add install under water with
Remove the more difficult implementation of anchor ear.Steel boxed cofferdam method, the material based on steel form dresses up casing by way of split is assembled,
Submerged.Blocked water by steel jacket box with back cover Shanghai and Nanjing figure into cofferdam, anhydrous construction environment is provided for pier construction in water.Examine
Consider that steel jacket box processing, transport and installation period are long, cost input is big, is more suitable for the ultra-deep depth of water in bridge spanning the sea, Duo Geshui
Middle pier continuously has enough to meet the need construction.
The content of the invention
It is an object of the invention to solve at least the above, and provide the advantage that at least will be described later.
Bottom technique is hung it is a still further object of the present invention to provide a kind of pier, it can improve the steady of pier lifting stand
On the basis of qualitatively, the pier that two adjacent bridge steel pile tubes can be completed simultaneously hangs bottom operation, and activity level is high, and operation
On the two ends of the first shoulder pole girder in journey, the second shoulder pole girder, the 3rd shoulder pole girder, crossbeam, longeron and the second round steel suspension rod can return
Receive and recycle, effectively save construction cost, it is adaptable to which in water or land route different types of rridges pier is constructed.
Bottom technique is hung there is provided a kind of pier according to object of the present invention and further advantage in order to realize, including with
