Description
Technical field
It the utility model is related to Bridge Construction field, and in particular to a kind of mud for water Bridge cast-in-situ bored pile
Starch the circulatory system.
Background technology
With the fast development of social economy and traffic transport industry, Urban Bridge Construction just deploys on a large scale, across lake
Pool, the bridge in river are also more and more.During Bridge Pile Foundation Construction, mud pit need to be largely used, it is more using soil at present
Cubic meter of stone cofferdam forms mud pit or finished steel mud pit.However, mud pit or finished steel mud are formed using cubic metre of earth and stone cofferdam
There is the defects of certain in stock tank, such as forming mud pit using cubic metre of earth and stone cofferdam expends substantial amounts of artificial, material and machinery expenses
It is very high, and lake or river course are taken, polluted water and retardance current, particularly easily occur flood in flood season and pour in down a chimney cofferdam, enclose
Weir such as caves at the accident, and potential safety hazard is big, pollutes environment；And finished steel mud pit is used, it will be cleared up first into slag bath before perfusion
Totally, and evacuate internal mud, and ensure mud pit, mud pit, slurry transport truck have enough capacity and filled to store in place
The mud discharged during note, and the Spatial General 6 R of finished steel mud pit is not very big, the buffer-precipitation that mud can not be good,
Borehole cleaning is inefficient, and needs the sediment outward transport inside frequent cleaning, operationalizes very cumbersome, also takes up natively
Limited over-water construction working face.Therefore, it is necessary to prior art is improved.
The content of the invention
The purpose of this utility model is, in view of the shortcomings of the prior art, there is provided a kind of cyclic space is big, mud sediment effect
The good mud circulating system for water Bridge bored pile construction of fruit.
The technical solution adopted in the utility model is：A kind of mud cyclic system for water Bridge bored pile construction
System, including the cofferdam in water, there are multiple Bored Pile of Bridge in cofferdam, be correspondingly configured with the datum hole of each Bored Pile of Bridge
One vertical steel pile casting, the both ends open of steel pile casting；The mud for connection is installed between two adjacent steel pile castings
Chute, mud chute are in tilted layout；The first slush pump is provided with cofferdam, the steel pile casting being connected with mud chute upper end passes through
The outlet of pipeline and the first slush pump, the entrance of the first slush pump directly connect with the mud in cofferdam；With mud chute
The second slush pump is provided with the connected steel pile casting in lower end, the steel pile casting being connected with mud chute upper end passes through pipeline and the second mud
The outlet of pump.
By such scheme, dense mesh is installed in the lower end exit of mud chute.
By such scheme, the lower end of mud chute is provided with gravel outlet.
By such scheme, clay layer that the lower end of the steel pile casting is stretched into datum hole.
By such scheme, the top in the cofferdam is higher by 1m than highest water level on records.
Compared with prior art, the beneficial effects of the utility model are：
1st, by the use of needing the cofferdam of construction bearing platform, without reconstruction mud pit in addition, to reduce and apply as mud pit originally
Work cost；Simultaneously as cofferdam volume is big, the cyclic space is big, mud sediment it is better, and adjacent steel pile casting plays tentatively
Precipitation and buffered water stream percussion, mud in cofferdam can gentle quickly precipitation, can reach the purpose of rapid borehole cleaning.
2nd, will transport outward mud after the completion of all pile foundation constructions in a cushion cap again, mud be precipitated into dregs or
Mud, it is not necessary to frequently transport outward mud, improve efficiency of construction, reduce construction cost；It it also avoid simultaneously to water body environment
Pollution, protect environment.
