Abstract
This utility model discloses the anchor bit of a kind of Recyclable anchor rope, including drill bit, drilling rod and the drill rod connector being connected with drilling rod, Grouting Pipe is set inside drilling rod, arranging anchor cable fixed cover outside drilling rod, the two ends of described anchor cable fixed cover arrange bearing, and drill rod sleeve is connected in bearing；The outside of anchor cable fixed cover arranges even number groove, and the bottom of groove arranges one of them hole connected with adjacent grooves, and described hole is disposed radially, and cable wire is set in described hole；The degree of depth of groove is more than the diameter of cable wire.The utility model has the advantages that: Recyclable anchor rope after construction, it is to avoid prior art does not the most reclaim anchor cable, cause serious underground pollution, and the anchor cable that stays becomes the defect of underground obstacle of successive projects construction.
Description
Technical field
This utility model relates to building field, and a kind of drill bit, is more specifically a kind of drill bit with anchor cable.
Background technology
Anchor cable reinforcement technique was successfully applied in the dam body of hydroelectric project as far back as 1933 by Algerian engineer
In reinforcing, hereafter developed rapidly, be widely used in the every field of Geotechnical Engineering.China's anchor cable reinforcement technique begins
In the application in the right bank stabilization of dam foundation of prunus mume (sieb.) sieb.et zucc. scenery with hills and waters storehouse in 1964, start this technology from the seventies and lead in national defence, water power, mine etc.
Progressively begin to use in territory.Since the eighties, anchor cable reinforcement technique is largely used to engineering, and in testing equipment and construction technology etc.
Research aspect achieves bigger progress.
Prestressed anchor reinforcement protects, and it is to utilize anchor cable surrounding formation rock soil classifiction to carry out drawing of transferring structure thing
Power or the homeostasis of holding stratum excavation face, due to the use of anchor cable, make anchoring stratum produce compressive stress district and to reinforcing ground
Layer plays reinforced action；The intensity on stratum can be strengthened, improve the mechanical property on stratum；Structure and stratum can be made to interlock in one
Rise, form a kind of cooperative complex so that it is can effectively bear pulling force and shearing, and can improve on potential slide surface
Shearing strength, stops slope-mass slide displacement effectively.
Anchor cable its support reinforcement is the important support pattern of one of building foundation pit, is used for safe class and requires higher or engineering
Larger base pit engineering, after prior art does not reclaims, and causes serious underground pollution, and the anchor cable stayed becomes
The underground obstacle of continuous engineering construction.Chinese Patent Application No. 201210290137.6 discloses a kind of recyclable post stretching and in advance should
Power anchored pile and construction method thereof, be characterized in including: cementitious composite soil pile body and the anchor cable going deep into pile body, anchor cable gos deep into pile body
One end connect have drill bit.Construction method includes: assembles and positions；Slip casting with move back bar；Stretch-draw and locking；Reclaim.Its recovery side
Method is that anchor cable carries out stretch-draw recovery, and stretch-draw pulling force is more than the marginal value of safe pin fracture and anchor cable top layer and cementitious composite
Frictional resistance between soil, anchor cable departs from safe pin, extracts out after reclaiming reusable.The method is highly unstable, usually
Cause the safe pin fracture when grappling, do not have the effect of anchor cable.
Summary of the invention
For solving above-mentioned technical problem, the purpose of this utility model is to provide the drill bit of a kind of Recyclable anchor rope, concrete skill
Art scheme is as follows:
The anchor bit of a kind of Recyclable anchor rope, including drill bit, drilling rod and the drill rod connector being connected with drilling rod, in drilling rod
Portion arranges Grouting Pipe, arranges anchor cable fixed cover outside drilling rod, and the two ends of described anchor cable fixed cover arrange bearing, and drill rod sleeve is connected on axle
In holding；The outside of anchor cable fixed cover arranges even number groove, and the bottom of groove arranges and connects with one of them of adjacent grooves
Hole, described hole is disposed radially, and cable wire is set in described hole；The degree of depth of groove is more than the diameter of cable wire；
For preventing stress from concentrating on some sectional position of pile body, the length of groove is different, at the axial direction of groove
All with multiple described hole is set, so according to practical situation, the setting of anchor cable can be adjusted.
The utility model has the advantages that: Recyclable anchor rope after construction, it is to avoid prior art does not the most reclaim anchor
Rope, causes serious underground pollution, and the anchor cable stayed becomes the defect of the underground obstacle that successive projects is constructed.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the Section A-A schematic diagram of Fig. 1；
Fig. 3 is the B direction view of Fig. 2.
Detailed description of the invention
Illustrate this utility model below in conjunction with the accompanying drawings, as shown in Figure 1-Figure 3, including drill bit 1, drilling rod 2 and with drilling rod 2
The drill rod connector 3 connected, drilling rod 2 is internal arranges Grouting Pipe, arranges anchor cable fixed cover 5, described anchor cable fixed cover 5 outside drilling rod
Two ends bearing 6 is set, drilling rod 2 is socketed in bearing 6；The outside of anchor cable fixed cover 5 arranges even number groove 8, the present embodiment
Being 8 grooves, practice can be adjusted to 6,10, the even numbers such as 12 in producing；The bottom of groove 8 is arranged and adjacent grooves
The hole 9 of one of them connection, described hole 9 is disposed radially, and cable wire 7 is set in described hole 9；The degree of depth of groove 8 is more than cable wire 7
Diameter；Backstop apparatus 4 is set between drilling rod 2 and drill rod connector 3, with the axial displacement of fixed drill bit；Described anchor cable structure is for moulding
In material sheath, steel strand wires are set, between steel strand wires and sheath, fill solid oil, during recovery, steel strand wires are pulled out from sheath
Go out.
Construction procedure of the present utility model is: boring → insert anchor cable body → injection cement mortar → stretch-draw → anchoring.It is executed
Work has drawn the technological merit of other anchor cable, rational in infrastructure reliably, easy construction.Anchor cable is in crimping shape in supporting body end
State, is in free state in sleeve pipe.
Reclaim construction point
(1), in anchor cable construction, the hole after boring cleans notably, it is ensured that can not there is mud in hole, especially at earth
In construction.
(2) backfill mortar depositing construction is critical process, in mainly cement grout must not leak into anchor cable protection set, otherwise can
Cause anchor cable to consolidate, affect the smooth recovery of anchor cable.
(3) strict protective measure be must take after anchor cable construction, recovery and the recycling thereof of anchor cable otherwise can be affected.
(4) the bundle number used according to anchorage cable design, its anchor head cushion block, anchor head, recovery fixture and punching hydraulic jack must
Must complement one another.
Anchor cable intermediate plate in design must consider reclaim time extract construction requirement, i.e. must leave groove and recovery in end
The latch fitting used.
Recyclable anchor rope has easy construction, safe and reliable, and recycling resource, labor strength are low, reduce environment
The advantages such as pollution.
