Description of the drawings
Fig. 1 is the schematic diagram of the half casing guncreting pile of one embodiment of the invention.
In figure：
1- casings；2- hydraulic pressure vibration hammers；3- triaxial cement mixing piles.
Specific implementation mode
Below in conjunction with the drawings and specific embodiments to half casing guncreting pile construction equipment proposed by the present invention and construction method
It is described in further detail.According to following explanation and claims, advantages and features of the invention will become apparent from.It should be noted
That attached drawing is all made of very simplified form and uses non-accurate ratio, only to it is convenient, lucidly aid in illustrating this hair
The purpose of bright embodiment.For sake of convenience, "upper" described below, "lower" are consistent with the upper and lower direction of attached drawing, but this is not
The limitation of technical solution of the present invention can be become.
The present invention is illustrated by taking certain base pit engineering as an example, about -0.500 meter of nature terrace relative elevation, foundation pit week skirt
Watch box combines outside 3 water-stop curtain of triaxial cement mixing pile using guncreting pile, and uses " pile wall interaction " technology, vertically arranged
Twice armored concrete horizontal supporting system.
It is pressed with reference to Fig. 1 half casing guncreting pile construction equipments that the present invention will be described in detail and using the construction equipment
Fill the construction method of pile driving construction.
Embodiment one
The half casing guncreting pile construction equipment of the present embodiment, including the double dynamical original state of built-in bolt blade fetch earth drilling machine；
Original state fetches earth guncreting pile frame, crawler crane, digging machine, concrete pump and casing 1, and crawler crane is for lifting steel reinforcement cage, digging machine
For assisting transhipment original state to fetch earth the soil body of drilling machine taking-up, the length of casing 1 is the half of guncreting pile pile body height；One cooperation is set
It is placed in the hydraulic pressure vibration hammer 2 on 1 top of casing.
Preferably, original state fetches earth, drilling machine is that the double dynamical original state of long spire fetches earth drilling machine, and pore-forming efficiency is high, and hole quality is good.
Casing 1 includes power head and cylinder, and cylinder is the standard knot steel pile casting that length is 12m, to facilitate the insertion of casing 1 to construct.
Good protection is played to pile using casing 1, collapse hole, slag inclusion can be avoided in constructing operation, improve guncreting pile at
Quality of pile.
Preferably, the depth that casing 1 squeezes into the soil body is the half of guncreting pile pile body height, guncreting pile is compared on the top of casing 1
The high 1m in top of pile body.
Embodiment two
Correspondingly, the present embodiment additionally provides the construction method of half casing guncreting pile.Referring Figure 1, half casing pressure
The construction method for filling stake, includes the following steps：
Step 1: passing through measurement markers stake position.Specifically, first according to building orientation axis, people is measured by sole duty
Member presses stake bit plan accurately by the setting-out of stake position to scene, and adds lime point as stake bit identification using wooden bat is inserted.When
So, in order to improve into pile verticality, smooth construction site is needed, stake machine is kept to be horizontal.
Step 2: providing aforementioned construction equipment, casing 1 is buried in drilling, the double dynamical original state of built-in helical blade takes
Cutting soil is bored under earth boring auger machine and forms stake holes, while soil body original state in casing 1 being taken out, and taken out using digging machine auxiliary cleaning
Soil block.
Step 3: after shield-tube embedment in place after, casing power head and upper section casing are detached from, and holding casing is motionless, drilling rod after
Continuous drilling is until stake bottom designed elevation.
Step 4: after casing 1 and drill bit reach designed elevation, casing power head is detached from upper section cylinder, keeps casing 1
It is motionless, drilling rod 200mm is promoted, decentralization conduit to stake bottom position begins pumping concrete to stake top absolute altitude.Certainly, concrete pumping
Should be carried out continuously, avoid caused by backstage feeding is slow it is under feeding, shut down phenomenon to be expected；Pump concrete reach 1m height after again
Start to carry brill, the pump concrete in Ti Zuan, and control puies forward drilling speed rate and with pump output matches；The row of must assure that in formation of pile
Air valve works normally, and prevents that plugging occurs in formation of pile；Hopper inner concrete face height is remained in pumping procedure not
Less than 400mm, plugging is caused to prevent sucking air.
Step 5: steel reinforcement cage is hung in above stake holes using crawler crane and is directed at limit；Then steel reinforcement cage is by dead weight
It is inserted into concrete, its suffered resistance gradually increases with the constantly sinking of steel reinforcement cage, under waiting for that steel reinforcement cage can not rely on dead weight to continue
It is heavy, start the vibrator that steel reinforcement cage delivers bar top so that steel reinforcement cage body vibration sinks down into a bottom.Steel reinforcement cage integral manufacturing and
At, therefore lifting construction is required relatively high.The lifting of steel reinforcement cage should use 4 points of liftings, and should ensure that straight lifting；Moreover,
After steel reinforcement cage hangs ground, straight lifting is realized by pulley of the hoisting wirerope on crane ditch using centre-of gravity shift principle
It is converted into vertical lifting, in order to enter hole；Finally, each lifting point should reinforce its rigidity and stress, prevent because of steel reinforcement cage itself weight
Power is overweight and deforms.
Particularly, casing 1 should be pulled out after the completion of steel reinforcement cage is inserted into.In step 5, when casing 1 starts to pull out, original place is answered
It is extracted again in rotation after rotation 5S.
Particularly, since steel reinforcement cage insertion is inserted into using vibrations form, steel reinforcement cage delivers the bar meeting of pulling out after being inserted in place
Decline along with concrete horizontal, in step 5, progress concrete secondary is needed to pour.
In conclusion the present invention carries out the construction method of half casing guncreting pile using construction equipment, using built in half casing
The double dynamical original state of helical blade, which fetches earth, bores cutting soil under drilling machine and forms stake holes, while soil body original state in casing being taken out, pressure
It is inserted into steel reinforcement cage after filling concrete, reinforced concrete pile is formed after extracting casing.The construction method is generated without mud, protection ring
Border；The construction method carries out guncreting pile construction not collapse hole, and vertical precision is high, and pile quality is good；The construction method carries out guncreting pile
Soil disturbance of constructing is small, and work progress influences surrounding enviroment small；Construction method progress guncreting pile construction, construction efficiency height,
Use cost is low.
Foregoing description is only the description to present pre-ferred embodiments, not to any restriction of the scope of the invention, this hair
Any change, the modification that the those of ordinary skill in bright field does according to the disclosure above content, belong to the protection of claims
Range.
