Detailed description of the invention
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but can not be used for limiting scope of the present utility model.
As Figure 1-3, in the water of the recyclable steel pile casting of the present embodiment, Bored Pile Foundation construction system comprises: be arranged in the marine drilling platform 1 on sea, crawler crane (figure does not mark) and the vibrating hammer 2 be located on marine drilling platform 1, be located at seabed and stablize the outer steel pile casting 4 between geological stratification 3 and marine drilling platform 1, the steel pile casting 5 being located at outer steel pile casting 4, the drill bit being located at steel pile casting 5 and the slush pump 8 be located on marine drilling platform; Be provided with reaction frame and jack 7 between the top mouth of interior steel pile casting 5 and marine drilling platform 1, described drill bit is connected with vibrating hammer 2 by crawler crane.
In the present embodiment, described jack can be hydraulic jack.The top mouth 25cm ~ 35cm higher than the top mouth of interior steel pile casting 5 of outer steel pile casting 4.The wall thickness of interior steel pile casting 5 is 10mm ~ 15mm.Internal diameter 0.8m ~ the 1.2m larger than the external diameter of interior steel pile casting 5 of outer steel pile casting 4.Internal diameter 8cm ~ the 12cm larger than the stake footpath of design stake of interior steel pile casting 5.
Described drill bit is divided into drill hammer 6 and becomes drill 9, and the diameter 4cm ~ 6cm larger than the stake footpath of design stake of drill hammer 6, becomes the diameter of drill 9 equal with the stake footpath of design stake.
Being combined as four groups and being along the circumferential direction uniformly distributed of described reaction frame and jack 7.
As Figure 1-3, in the water of the above-mentioned recyclable steel pile casting of the application of the present embodiment the recyclable steel pile casting of Bored Pile Foundation construction system water in Bored Pile Foundation foundation construction comprise the following steps:
S1. drilling platform 1 arranges crawler crane and vibrating hammer 2, slush pump 8 at sea.
S2. use crawler crane and the outer steel pile casting of vibrating hammer sinking, make the end mouth injection of outer steel pile casting stablize in geological stratification to seabed;
The internal diameter of interior steel pile casting 5 is than large 10 centimetres of the stake footpath designing stake, and the wall thickness of interior steel pile casting 5 is 12 millimeters, larger than the external diameter of interior steel pile casting 5 1.0 meters of the internal diameter of outer steel pile casting 4.
S3. use crawler crane and vibrating hammer 2 steel pile casting 5 in sinking in steel pile casting 4 outside, between the top mouth and marine drilling platform 1 of interior steel pile casting 5, reaction frame and jack 7 are installed;
Specifically, the counterforce device pushing up installation on mouth and marine drilling platform 1 at interior steel pile casting 5 is made up of four large-tonnage hydraulic jacks and special reaction frame, is arranged at the quarter turn place of interior steel pile casting 5 respectively, and installing must safely, firmly, reliably.
S4. by crawler crane and vibrating hammer 2, drill hammer 6 is put in interior steel pile casting 5;
The diameter of drill hammer 6 is than large 5 centimetres of the stake footpath designing stake, and meanwhile, the diameter of drill hammer 6 is less than the internal diameter of interior steel pile casting 55 centimetres.
S5. as shown in Figure 2, start drill hammer 6 and start drilling construction, along with the continuous propelling of boring, startup reaction frame and jack 7 inwardly steel pile casting 5 apply downward pressure, interior steel pile casting 5 by gradually at the bottom of press-in hole, is stablized in geological stratification 3 until the end mouth of interior steel pile casting 5 arrives seabed under the effect of downward pressure;
Concrete, drill hammer 6 starts drilling construction, along with the continuous drilling depth of boring, start counterforce device and apply downforce, interior steel pile casting 5 is subject to the effect of downforce, adds from gravity, be pressed at the bottom of hole gradually along outer steel pile casting 4 hole wall, reach the effect of " follow-up ", interior steel pile casting 5 always " follow-up " to seabed is stablized in geological stratification 3, guarantee not spillage, not boring a hole can stop " follow-up ".
S6. with powerful slush pump 8, the boring mud in interior steel pile casting 5 is extracted in the gap between outer steel pile casting 4 and interior steel pile casting 5, forms circular boring mud mud off;
Because the diameter difference of interior steel pile casting 5 and outer steel pile casting 4 is designed to 1 meter, therefore there is enough spaces can deposit more boring mud and mud, solves the problem of mud circulation.
S7., as shown in Figure 3, after interior steel pile casting 5 stops " follow-up ", drill hammer 6 is changed into the one-tenth drill 9 of design pile foundation construction, start into drill 9 until complete the pore-forming of drilled pile;
Clay be backfilling into always higher than design stake stake top mark high 1.8 meters ~ 2.2 meters of till, be preferably 2 meters in the present embodiment.
S8. respectively the boring mud in the gap between outer steel pile casting 4 and interior steel pile casting 5 and the new boring mud in interior steel pile casting 5 are extracted out with slush pump 8, then, in the gap outside between steel pile casting 4 and interior steel pile casting 5, backfill clay;
Concrete, after pore-forming, extract boring mud between interior steel pile casting 5 and outer steel pile casting 4 and mud out with slush pump 8, boring mud is abandoned outward, and mud then can recycle, then, backfill clay in gap between interior steel pile casting 5 and outer steel pile casting 4, be backfilled to more than design stake top mark height 2 meters of always.
S9. concrete perfusion in pore-forming, after filling concrete completes, extracts interior steel pile casting 5 with crawler crane and vibrating hammer 2 immediately.
S10. when after the concrete initial set poured in pore-forming, slowly vibrate with crawler crane and vibrating hammer and extract outer steel pile casting.
After filling concrete completes, extract interior steel pile casting 5 immediately with crawler crane and vibrating hammer 2, owing to there being the clay dado of 50 cm thicks between interior steel pile casting 5 and outer steel pile casting 4, therefore, concrete can not scatter and disappear and collapse.It should be noted that the speed of extracting is unsuitable too fast.Outer steel protects, 4 after concrete initial set slowly vibration extract.Enforcement of the present utility model, need the counterforce device of practical a, strong operability, and drilling platform also needs to strengthen, to bear huge downforce.In addition, the clay dado between interior steel pile casting 5 and outer steel pile casting 4 don't fail to be reliable and stable, otherwise after interior steel pile casting 5 extracts, if retaining wall collapses, certainly will affect the concrete quality of pile foundation.
In the water of recyclable steel pile casting of the present utility model, Bored Pile Foundation construction system and construction method thereof have employed inside and outside clad steel casing, by the follow-up of interior steel pile casting and boring mud retaining wall and mud off with the use of, after achieving pile, steel pile casting extracts recovery, reduce the construction cost of drilled pile, achieve the recycling of steel pile casting, solve drilled pile steel pile casting unrenewable problem in profundal zone in prior art.
Embodiment of the present utility model provides for the purpose of example and description, and is not exhaustively or by the utility model be limited to disclosed form.Many modifications and variations are apparent for the ordinary skill in the art.Selecting and describing embodiment is in order to principle of the present utility model and practical application are better described, and enables those of ordinary skill in the art understand the utility model thus design the various embodiments with various amendment being suitable for special-purpose.
