Abstract
The present invention relates to an earth anchor rod hole-forming process whose drill pipe can be used as hole-protecting sleeve. Said hole-forming process includes hole-forming drilling process step, it utilizes the drilling tool with auger-drill head, and adopts wet drilling method or dry drilling method to make drilling operation. Said drilling tool with auger-drill head is composed of auger-drill head, tool joint box and pin, drill pipe and drill pipe joint. Said invention also provides the concrete steps of said hole-forming process and its operation method.
Description
(1) technical field
The invention belongs to the geotechnical engineering field, specifically relate to anchor pole in a kind of foundation pit supporting project (rope) pore-forming technique.
(2) background technology
In geotechnical engineering, the anchoring of extensive use, particularly in the foundation ditch slope protection works, soil anchor bolt (rope) technology is occupied critical positions, and it combines with various slope protection pile becomes the effective means of control lateral displacement in the soil excavation construction.But for a long time, because the complexity of soil layer, most of stratum easily caves in and is difficult for pore-forming, brings very big difficulty for anchor pole (rope) construction.In hole ground anchor (rope) construction of collapsing two kinds of methods are arranged at present: a kind of is pipe anchor rod, and drilling rod double as anchor pole is stayed in the hole.Construction cost and construction costs have been improved; Another kind method is to advance with managing and protecting hole drill, this kind method complex procedures, and efficient is low.
(3) summary of the invention
Purpose of the present invention is anchor pole (rope) pore-forming technique that a kind of drilling rod double as guard aperture sleeve pipe is provided on the stratum, hole of collapsing.This technology can improve efficiency of construction, reduces construction cost and improve anchoring quality.
The technical scheme that adopts is:
The soil anchor bolt pore-forming technique of drilling rod double as guard aperture sleeve pipe comprises the steps:
1, pore-forming creeps into.Pore-forming creeps into the compaction rate of looking the stratum can adopt two kinds of methods:
(1) wet brill method pore-forming.Employing has the drilling tool of augers, sends into flushing liquor (cement paste or clear water) in drilling rod, is carried out to hole drill and advances, to desired location.Then drilling rod is stayed in the hole as interim guard aperture sleeve pipe, promptly drilling rod double as guard aperture sleeve pipe uses.
(2) dry drill method pore-forming.Adopt the drilling tool of band augers, the flushing liquor dry drill method pore-forming of not bothering to see me out creeps into, and to desired location, then drilling rod is stayed in the hole as interim guard aperture sleeve pipe.
2, anchor pole (rope) contacts or docks with augers.With anchor pole (rope) or have the anchor pole (rope) that docks locking device and send into from drill pipe bore, when the front end of anchor pole (rope) contacts with augers, or the connector in the butt joint locking device insertion augers, just automatically lock, block the jail after the contact, augers and anchor pole (rope) are connected as a single entity.
3, drilling rod is proposed.After anchor pole (rope) and augers are determined to contact or dock, be about to drilling rod and from take off (or lifting from) with the augers junction is counter after, whole drilling rods proposed, augers is stayed in the hole with anchor pole (rope) as the enlarged footing of anchor pole (rope).
4, slip casting.When adopting wet brill method, creep into and do not need other slip casting owing to send into cement paste; When adopting dry drill method, need to send into Grouting Pipe simultaneously sending into anchor pole (rope), carry out follow-up slip casting.
The present invention has following advantage:
1, efficiency of construction height.On the stratum, hole of collapsing because drilling rod double as guard aperture sleeve pipe compares with follow-up casing pipe hole forming method and saved the sleeve pipe follow-up and sleeve pipe withdraws from operation, realized that the pore-forming rate of penetration is fast, anchor pole (rope) send into butt joint soon and drilling rod withdraw from soon, efficiency of construction is improved greatly.
2, construction cost is low.Owing to select for use rod iron or steel strand to greatly reduce cost than pipe anchor rod as anchoring material.
3, because anchor pole (rope) front end has adopted augers as enlarged footing, improved the supporting capacity of anchor pole (rope) greatly.
(4) description of drawings
Fig. 1 is a kind of drilling tool structure schematic diagram in the technology of the present invention.
Fig. 2 is a kind of anchor pole (rope) and augers docking structure schematic diagram in the technology of the present invention.
(5) specific embodiment
Embodiment one
The soil anchor bolt pore-forming technique of drilling rod double as guard aperture sleeve pipe comprises the steps:
1, pore-forming creeps into, with the drilling tool that has augers (as shown in Figure 1), the drilling tool that has an augers by augers 1, female easily reversal connection hand (or female plug catcher) 2, public easily reversal connection hand (or male plug catcher) 3, drilling rod 4, drilling rod catcher 5 and augers 1 endoporus fixedly lock tube 6 form.Female easily reversal connection hand 2 is fixedlyed connected with augers 1 rear end, and public easily reversal connection hand 3 is fixedlyed connected with the drilling rod front end; Spin between the easy reversal connection hand of male and female, drilling rod 4 is connected to form by a plurality of drilling rod catchers 5 of a plurality of internal flush drill pipe 4 usefulness.
2, when the drilling tool that has augers creeps into desired location, the anchor pole (rope) that will have butt joint locking head assembly is sent into (as shown in Figure 2) from drill pipe bore.Butt joint locking head assembly is made up of tapered end 7, three card keys 8 and solid rope slocket 9.Have 10, three cards of three keyways key 8 to be installed in respectively in three keyways 10 on the tapered end 7, the front end of three card keys 8 is connected with tapered end 7 by bearing pin 14 respectively.Be equiped with shell fragment 11 respectively in three keyways 10, an end of shell fragment 11 is fixedly connected with corresponding card key 8, and the other end is then replaced in keyway 10 bottoms.Tapered end 7 rear ends are connected with solid rope slocket 9, Gu the fixing many anchor cables (rod iron or steel strand) 12 of rope slocket 9 other ends.When tapered end 7 inserted the lock tube 6 of augers 1, three card keys 8 opened at once and block, and tapered end 7 can not withdraw from.
3, drilling rod withdraws from.After affirmation anchor pole (rope) docks with augers 1 and blocks the jail, drilling rod from counter the taking off of easy reversal connection hand (or grafting hand place) (or raising), is all proposed drilling rod then, anchor pole (rope) and augers are stayed in the hole.
Embodiment two
Processing step and embodiment one that embodiment two is adopted are basic identical, and difference is that anchor pole (rope) 12 is rod iron or steel strand, is equiped with Grouting Pipe 13 in anchor pole (rope) 12 endoporus.
