Description
Technical field
The present invention relates to existing driven cast-in-place pile technical field, specially a kind of follow-up casing pile foundation drilling construction method.
Background technique
Existing driven cast-in-place pile is one of numerous type pile foundations in civil construction project.System is using the design ruler with stake
Very little adaptable steel pipe (i.e. casing), after sinking in soil after pile top in end sleeve, hangs framework of steel reinforcement, then side in casing
The vibration of casting concrete side or hammering tube drawing, mechanical pudding concrete when using tube drawing and form required bored concrete pile.This
Kind construction method is suitable for having the case where underground water, quicksand, mud.Using hammer piling equipment immersed tube, tube drawing pile, referred to as
Hammer hidden pipe caisson pile.Utilize vibrator vibration sinking tube, tube drawing pile, referred to as vibrator pipe sinking cast-in-place pile.According to immersed tube method and
Difference is vibrated when tube drawing, casing pipe hole forming bored concrete pile can be divided into hammer hidden pipe caisson pile, vibrator pipe sinking cast-in-place pile.The former is chiefly used in one
As cohesive soil, muck soil, sand and artificial earth fill's ground, the latter is in addition to range above, it may also be used for it is slightly close and in it is close broken
Stone soil base.In order to improve the quality and bearing capacity of stake, driven cast-in-place pile is applied frequently with singles' method, strike-on method, anti-plug method etc.
Work technique.
Follow-up casing pile foundation pore-forming can generate biggish noise when construction, and construction can all influence residence nearby every time
The living environment of the people, and Chang Tuzhi is harder when embedded casing, and casing is damaged, schedule delays, while in block stamp
The case where causing punching to shift vulnerable to the influence of underground soil property when punching, and can not carry out following
Work.

Word stake, which is squeezed into, surveys measured position；
Step 2: surveying measured pile center position in step 1, is loosened the soil, loosened the soil to the center using loosenning tiller
Range diameter be 400-450cm, after the completion of loosening the soil, using hoisting machine by shield-tube embedment in the position of pile center；
Step 3: having buried the outer surface above casing in step 2 is socketed a noise abatement set, and in noise abatement set inner ring
Lower section is installed with support annulus, adjusts the block stamp that hoisting machine has been hung, and makes the position control of centre weight and pile center fortunately
1.5cm interior；
It is impacted Step 4: hoisting machine begins through block stamp, mud off is used when impact, when block stamp is down toward casing 3-
After 3.5m, tup 2-3m is improved, and accelerate speed and be transferred to normal impact.
Step 5: improving tup again after impact depth is 7-8m, support annulus is taken out, then remove noise abatement set, will located
The one end for the mud managed is attached by feed pipe and tup, and is connected to waste tank by drainage conduit in the other side；
Step 6: impacting again by hoisting machine to it, and start the draining pump connecting with drainage conduit simultaneously, and
The suction pump that the starting of connecing property is connect with feed pipe makes the work of draining pump and suction pump alternately, head pressure in retaining hole
Balance, until punching reaches projected depth；
Step 7: punching, which reaches projected depth, to be made, hole depth is checked, hole location is checked, confirmation meets design
It is required that the registration that can fill in a form.
Preferably, the material of the casing is steel casing, and the internal diameter of casing is greater than cross pile 15cm, is higher by construction ground
Face 20-25cm.
Preferably, the support annulus is spring steel ring, has outside extensibility, and easily shrink.
Preferably, the bracing wire centre deviation of the end face center of the casing and cross pile is less than 5cm.
