In order to facilitate understanding above-mentioned technical proposal of the invention, below by way of in specifically used mode to of the invention above-mentioned
Technical solution is described in detail.
When specifically used, present invention brill carries out the preparation before drilling machine construction first；Specifically: first to construction site into
Row is smooth, and to guarantee drilling machine smooth running, positioning stablity, pile body is vertical；Then it discharges stake position and applies for checking and examination；Secondly, reserved construction
Vehicles while passing road guarantees that its traveling is unobstructed, then examines steel reinforcement cage, prepares stand-by；Finally, drilling machine is to good hole location, before spudding in
Drilling rod verticality is examined using theodolite, point-blank, stake position error is not more than 100mm to pile body, vertically after guaranteeing pile
It spends error and is not more than 1%.
Secondly, drilling machine drilling and forming hole；After drilling machine is ready, concrete pump pipe is connected, debugs ground pump running parameter, benefit
With mortar lubrication piping, after examining verticality, can spud in pore-forming；The drilling parameter of drilling machine should be selected according to strata condition
And adjusting, for example when entering layer of sand and boulder bed, should suitably slow down penetration rate, guarantee that hole wall is stablized；In drilling construction,
Boring mud is cleared in time using crowd shovel, guarantees place neat and tidy, is conducive to construct in next step；Drilling is stopped after reaching requirement hole depth
It bores.
Again, guncreting；The first step, plan concrete amount: according to the concrete condition of drilling such as features as poor geologic condition, collapse or
There is underpass etc., plan concrete side can expand fullness coefficient when measuring, to meet the casting designed elevation requirement of pile body concrete；Second step,
Concrete inspection: having to conscientiously check to live concrete, and rule of thumb, whether the concrete for checking scene has good workability,
Whether slump meets the requirements (180~220mm), and whether concrete isolates, and whether there is or not agglomerate, large-particle-size aggregate etc., nonconforming
Never allow to be poured；Third step, concrete pressure fill: examine qualified concrete to pass through in drilling rod press-in hole using ground pump through pump line,
Brill is mentioned in guncreting, until concrete surface reaches design height, in sand bed when guncreting, should suitably be slowed down and be mentioned
Drilling speed degree prevents from forming undergauge in sand bed；Concrete pouring should be more than 50~80cm of designed elevation, in order to guarantee stake top concrete
Label meets design requirement；Flexibly processing according to field condition thus；4th step, concrete test block production: each casting machine-team must not
Less than 1 group, every group 3.
Finally, fabrication of reinforcing cage and vibration are put；Fabrication of reinforcing cage should construct by design drawing, and be able to satisfy corresponding specification and want
It asks, ± 10 mm of main reinforcement spacing tolerance, ± 20 mm of stirrup spacing or spiral bar spacing tolerance, steel reinforcement cage diameter allows
± 10 mm of deviation, ± 50 mm of length of reinforcing cage tolerance, the steel reinforcement cage made should put a smooth location near the scene, just
It constructs in hanging；Fabrication of reinforcing cage should be first carried out before boring drill is marched into the arena, and guarantee to examine qualification at least 10 at the scene
Steel reinforcement cage is spare；On-the-spot record personnel will select steel reinforcement cage by design requirement according to pile No., and make a record；Before lifting by crane steel reinforcement cage
It should be by the steel reinforcement cage of quality inspection (never allowing not to be put into hole by what is checked)；The jail of suspension centre should be first checked for when lifting
Gu the adjunct on degree and cage；Hoistman should be noted that the instruction of commander's hand, gently lift by crane；Steel reinforcement cage, vibration are led in advance
Pipe, vibration hammer assemble, and are lifted to aperture together, steel reinforcement cage is slowly vibrated decentralization to requirement by starting vibration hammer after the completion for contraposition
Absolute altitude；Level elevation control is utilized when steel reinforcement cage is transferred, error is no more than ± 5cm, and steel reinforcement cage is placed among hole.
In conclusion the present invention using the dry pore-forming of long-spiral drilling machine, guncreting, fall plug in cage by the way of apply
Work, this form of construction work had not only reduced a large amount of discharges of live mud, but also improved construction speed, while also maintaining site operation
Civilization it is clean and tidy；This method has the advantages that design is reasonable, construction procedure is simple, while ensure that the accuracy and construction of construction
Quality.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
