Description
Technical field
The utility model belongs to poured pile base technical field in architectural engineering, and in particular to bored concrete pile boulder quickly clears up dress
Put.
Background technology
During the Wharf Construction of riverside, access bridge root needs several bent foundations of arranging, access bridge perpendicular to embankment simultaneously
Drop-over, access bridge part bored concrete pile region are in the range of embankment along the Yangtze dumped rocks protecting foundation, and riprap layer thickness about in 5m or so, fills
It is long from 40-54m to note stake stake, is both needed to penetrate existing embankment riprap layer during drilling construction, before bored concrete pile putting up platform waterborne, makes
Construction of removing obstacles is carried out to the jackstone of grout pile position near zone with grab bucket dredger, depth of removing obstacles is more than 5m, jackstone
Remove obstacles and use DZ60 vibration hammer sinking steel φ 1300mm casings after construction, sinking steel protecting canister construction smoothly, all steel pile castings under
Sink to position.
But putting up platform is completed on the water, convolution rig starts to find still have at the bored concrete pile hole position of part during drilling construction
Boulder is present, depth 10m or so about under mud face, size about 50cm or so, and common GPS type convolution rig can not be penetrated or broken
Broken boulder, other method drilling and forming hole need to be used, in this case, conventional use of is punching piling machine pore-forming, and punching is beaten
Stake machine is to lift block stamp to eminence using hoist engine, then reaches block stamp by boulder by boulder in freely falling body impact opening
Extruding treats that gaining rotary drill machine machine after huge stone handling again continues to creep into the purpose on hole wall after broken.
But it is bored concrete pile waterborne because engineering bored concrete pile is most of, does not consider that punching is beaten at the beginning of bored concrete pile Platform Designing waterborne
Stake machine load, if so using punching pile driving equipment, need to carry out consolidation process to existing bored concrete pile platform, it is necessary to expend a large amount of
Manually, material cost and duration need to lengthen, and for bored concrete pile using convolution rig in the case of being influenceed without boulder, the pore-forming time is about 20
Hour or so, if the use of the punching piling machine pore-forming time being about 70 hours or so after meeting boulder, single stake pore-forming is beaten using punching
Stake machine rubble need to increase the processing time of 50 hours, do not meet the construction period of engineering, also considerably increase cost of labor and set
Standby lease expenses.So it is badly in need of finding a kind of new boulder liquidating plan.
