Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of detailed description of the invention.
Clearly represent unless otherwise other, otherwise in whole manual and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or ingredient, and do not get rid of other element or other ingredient.
As shown in Figure 1, according to two kinds of embodiments of the specific embodiment of the invention be:
Embodiment 1
A kind of take-over type anchor pole, it comprises: the body of rod 1, adapter sleeve 2, anchor head 4, backing plate 6 and capping 8, wherein: the body of rod 1 is provided with the hollow tubular of opening in upper and lower two ends, at least two bodies of rod 1 are connected by adapter sleeve 2, preferably, the two ends up and down of adapter sleeve 2 are threaded connection with neighbouring two bodies of rod 1 respectively.When needing to install shorter anchor pole to side slope 9, can be only formed by connecting by adapter sleeve 2 by two bodies of rod 1, when longer anchor pole is installed as needed, then sequentially can be formed by connecting by adapter sleeve 2 by multiple body of rod 1, by forming anchor pole in the mode of adapter, when transporting, anchor pole can be split into multiple relatively short body of rod 1, effectively to avoid damaging the bending of anchor pole during transport.The diameter of adapter sleeve 2 is greater than the diameter of the body of rod 1, and the middle part of adapter sleeve 2 is provided with at least one first extravasating hole 3, when pour water in the body of rod 1 cement mortar time, cement mortar can be overflowed from through an extravasating hole 3.Preferably, the middle part of adapter sleeve 2 is circumferentially provided with several first extravasating hole 3 equably, thus cement mortar is successfully outwards overflowed fast, and be greater than the diameter of the body of rod 1 due to the diameter of adapter sleeve 2, cement mortar can produce resistance, to improve the breakout capacity of anchor pole to the two ends up and down of adapter sleeve 2 after solidifying.
As shown in Figure 1, backing plate 6 is sheathed on the top of the body of rod 1 being positioned at the top, and capping 8 is connected with the upper end of the body of rod 1 being positioned at the top, and can seal the opening of the upper end of the body of rod 1 of the top, and capping 8 is for being pressed in backing plate 6 on the surface of side slope 9.Preferably, capping 8 is concrete capping, and namely it is directly built by condensation soil and forms.Further preferably, between backing plate 6 and capping 8, be folded with a baffle ring 7, to reinforce the damage that backing plate 6 also prevents backing plate 6 effectively further.
Anchor head 4 is the hollow tube of upper end open, and its lower end is pointed.The diameter of anchor head 4 is greater than the diameter of the body of rod 1, and the upper end of anchor head 4 is sheathed on the lower end of the body of rod 1 being positioned at bottom, and anchor head 4 is provided with at least one second extravasating hole 5; Preferably, the middle part of anchor head 4 is circumferentially provided with several second extravasating hole 5 equably, overflows rapidly smoothly to enable cement mortar.Anchor pole can be made successfully to insert in the guide hole 10 of side slope 9 by arranging anchor head 5, and during cement injection mortar, after cement pump slurry overflows from the second extravasating hole 5, cement mortar produce active force to anchor head about 4 two ends, thus increases the breakout capacity of anchor pole.Further preferably, the diameter of anchor head 4 is identical with the diameter of adapter sleeve 2, to get out a guide hole 10 corresponding with the diameter of anchor head 4 and adapter sleeve 2 to facilitate in side slope 9, makes the gap between the overall and guide hole 10 of anchor pole more even.
Embodiment 2
As shown in Figure 1, a kind of mounting method of above-mentioned take-over type anchor pole, comprises the steps:
The first, side slope 9 gets out guide hole 10, and the diameter of guide hole 10 is greater than the diameter of anchor head 5 and adapter sleeve 2, when the diameter of anchor head 5 and adapter sleeve 2 is identical, can ensure that the gap between guide hole 10 and anchor pole entirety is more even.
The second, reaming is carried out in the position corresponding with the adapter sleeve 2 on take-over type anchor pole to described guide hole 10, to form the first chamber 11; And reaming is carried out to form the second chamber 12 to the lower end of guide hole 10.
3rd, assemble several bodies of rod 1, adapter sleeve 2 and anchor head 4, then the entirety after assembling is inserted in guide hole 10, because the lower end of anchor head 4 is pointed, can facilitates and successfully the body of rod 1 be imported in guide hole 10.
4th, the inner chamber toward the body of rod 1 fills cement mortar, and cement mortar is overflowed by the first extravasating hole 3 and the second extravasating hole 5 and filled up the first chamber 11, second chamber 12 and gap between the body of rod 1 and guide hole 10.And
5th, finally, the top cover upper padding plate 6 of the body of rod 1 in the top, and by capping 8, backing plate 6 is pressed in the surface of side slope 9.When baffle ring 7 is set between capping 8 and backing plate 6, first baffle ring 7 is sheathed on the top of the body of rod 1 of the top, then capping 8 is installed.
After cement mortar is solidified, the body of rod 1 can be made to be inserted in guide hole 10 securely, anchor pole 4 and adapter sleeve 2 can increase the active force of anchor pole and cement mortar, and the first chamber 11 and the second chamber 12 can increase the jam power of cement mortar and side slope 9, when side slope 9 is not destroyed, cement mortar slurry can not be pulled out.Thus effectively can improve the breakout capacity of anchor pole on the whole, to ensure the safety that side slope is stable for a long time.In addition, the present invention also can be applicable to the association areas such as underground construction, slope project, deep-foundation pit engineering, tunnel.
The aforementioned description to concrete exemplary of the present invention is to illustrate and the object of illustration.These descriptions not want the present invention to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.The object selected exemplary embodiment and describe is to explain certain principles of the present invention and practical application thereof, thus those skilled in the art can be realized and utilize various different exemplary of the present invention and various different selection and change.Scope of the present invention is intended to limited by claims and equivalents thereof.
