Abstract
The utility model belongs to the technical field of geotechnical engineering struts, a an anchor rope clamping orient device that is used for prestressing force coupled pole cable anchor system is related to, having rolling bearing on the foraminiferous fixed plate, foraminiferous fixed plate is asked for with the pole and is connected through rolling bearing between the adapter sleeve, foraminiferous fixed plate passes through pole cable adapter sleeve to be fixed on the outer wall of hollow drill, and evenly distributed has a guiding hole around the foraminiferous fixed plate, and the quantity of guiding hole is according to the magnitude determination of required anchor rope, in wearing anchor rope protective case in the anchor rope, anchor rope protective case passes guiding hole protection anchor rope, and the front end anchor of anchor rope is on foraminiferous fixed plate, its simple structure, convenient operation, it is safe in utilization, possess prestressed anchorage pole and prestressed anchorage cable anchor characteristic simultaneously.
Description
Technical field:
The utility model belongs to geotechnical engineering support technology field, relates to a kind of anchor cable locating guide device for prestressing force coupled pole rope anchoring system.
Background technology:
Along with the development of geotechnical engineering support technology, prestressed anchor, cable bolting technology have been widely used in the engineering constructions such as underground engineering wall rock supporting, slope retaining, pattern foundation pit supporting structure.At present, the prestressed anchor generally adopted or cable bolting technology are single support forms, less employing possesses the compound anchoring of prestressed anchor and prestressed cable anchorage feature simultaneously, its construction method adopts the form of first boring, grouting behind shaft or drift lining usually, but for weak soil or the kata-rocks soil body, owing to very easily there is collapse hole phenomenon after pore-forming, cause slip casting process normally to carry out, or have a strong impact on supporting effect, engineering safety is threatened; And, for single prestressed anchor, because its body of rod section area is larger, during Shi Hanzhang, the deflection that the body of rod produces is less, and the anchor effect of drawing of far-end being stablized to Rock And Soil is nothing like anchor cable, and anchor cable self can not resist the shear action of Rock And Soil around.Therefore, in the urgent need to designing a kind of anchor cable locating guide device for prestressing force coupled pole rope anchoring system.
Summary of the invention:
Goal of the invention of the present utility model is the shortcoming overcoming prior art existence, seek to design the anchor cable locating guide device being provided for prestressing force coupled pole rope anchoring system, make prestressing force coupled pole rope anchoring system can give full play to the anchoring property of anchor cable, huge anchored force is provided, and anchored force is reliably passed to far-end by the stable Rock And Soil of anchoring, strengthen stablize Rock And Soil with far-end draw anchor effect, the shearing slip effect of Rock And Soil around anchor pole opposing can be realized again, also can be applicable to the Unfavorable geology condition that collapse hole easily occurs simultaneously.
To achieve these goals, agent structure of the present utility model comprises hollow drill, anchor cable protective sleeve, anchor cable, bar rope adapter sleeve, fixed head with holes, rolling bearing and pilot hole; With rolling bearing on fixed head with holes, be connected by rolling bearing between fixed head with holes with bar rope adapter sleeve; Fixed head with holes is fixed on the outer wall of hollow drill by bar rope adapter sleeve, avoids the setting of rolling bearing and weakens the thickness of hollow drill, being convenient to be arranged on hollow drill simultaneously; The surrounding of fixed head with holes is evenly distributed with pilot hole, and the quantity of pilot hole is determined according to the quantity of required anchor cable; Be through in anchor cable protective casing in anchor cable, anchor cable protective casing, through pilot hole protection anchor cable, makes anchor cable can carry out stretch-draw smoothly, Shi Hanzhang after slip casting; The front end of anchor cable is anchored on fixed head with holes; rear end freely; anchor cable and anchor cable protective casing can rotate freely around hollow drill; during use; hollow drill rotates into stratum under external rig twisting force, and anchor cable and anchor cable protective casing do not rotate, and successfully enter stratum with hollow drill; slip casting is solidified rear to anchor cable Shi Hanzhang, forms the prestressing force coupled pole rope anchoring system simultaneously possessing prestressed anchor cables and prestressed anchor bolts anchorage characteristics.
Compared with prior art, its structure is simple, and easy to operate, use safety, possesses prestressed anchor and prestressed cable anchorage feature simultaneously for the utility model.
Accompanying drawing illustrates:
Fig. 1 is agent structure schematic top plan view of the present utility model.
Fig. 2 is agent structure generalized section of the present utility model.
Detailed description of the invention:
Below by embodiment, also the utility model is described in further detail by reference to the accompanying drawings.
Embodiment:
The agent structure of the present embodiment comprises hollow drill 1, anchor cable protective sleeve 2, anchor cable 3, bar rope adapter sleeve 4, fixed head with holes 5, rolling bearing 6 and pilot hole 7; With rolling bearing 6 on fixed head 5 with holes, be connected by rolling bearing 6 between fixed head 5 with holes with bar rope adapter sleeve 4; Fixed head 5 with holes is fixed on the outer wall of hollow drill 1 by bar rope adapter sleeve 4, avoids the setting of rolling bearing 6 and weakens the thickness of hollow drill, being convenient to be arranged on hollow drill 1 simultaneously; The surrounding of fixed head 5 with holes is evenly distributed with pilot hole 7, and the quantity of pilot hole 7 is determined according to the quantity of required anchor cable 3; Be through in anchor cable protective casing 2 in anchor cable 3, anchor cable protective casing 2 protects anchor cable 3 through pilot hole 7, makes anchor cable 3 can carry out stretch-draw smoothly, Shi Hanzhang after slip casting; The front end of anchor cable 3 is anchored on fixed head 5 with holes; rear end freely; anchor cable 3 and anchor cable protective casing 2 can rotate freely around hollow drill 1; during use; hollow drill 1 rotates into stratum under external rig twisting force, and anchor cable 3 and anchor cable protective casing 2 do not rotate, and successfully enter stratum with hollow drill 1; slip casting is solidified rear to anchor cable 3 Shi Hanzhang, forms the prestressing force coupled pole rope anchoring system simultaneously possessing prestressed anchor cables and prestressed anchor bolts anchorage characteristics.
