Abstract
The utility model relates to a novel anchor which comprises a doubled anchor body. The doubled anchor body comprises a straight line segment and a turning segment. The turning segment is provided at one end of the doubled anchor body. The straight line segment is integrated with the turning segment. The turning segment is provided with an adjusting ejection mechanism which can control the radius of the turning segment. As the novel anchor is provided with the adjusting mechanism which can control the radius of the turning segment, the placing of the novel anchor into the anchor hole of the rock and soil mass is more convenient. Furthermore, when the turning segment is placed into an anchoring segment, the adjusting mechanism can be loosened so that the radius of the turning segment can be restored to an original state. Partial component of the adjusting mechanism remains in a slurry injection member of the anchoring segment for increasing partial compressive strength.
Description
Technical field
The utility model relates to a kind of anchor pole, and particularly a kind of novel anchor rod that can conveniently insert geotechnical body that is applied to soil layer or geotechnics foundation and slope retaining belongs to the engineering infrastructure technical field.
Background technology
Along with the propelling of urbanization process, the construction of underground installations such as underground parking, underground walkway, subterranean commercial area, underground railway need be carried out pattern foundation pit supporting structure.Though support the variety of issue that produces in the time of solving the underground structure construction well in adopting, its cost height, long in time limit, the inconvenient shortcoming of underground structure construction can not satisfy the urban development needs.
In the prior art, anchor pole is widely used in the geotechnical engineering, obtained extraordinary result of use, but the anchor pole of using all is disposable use usually, and using the back anchor rod body is retained in the soil layer, not only waste material also to adjacent structure construction formation obstacle, is handled the expense of underground obstacle when increasing later development.
Usually the rock-bolt length of using in the engineering is about 10～50 meters at present, adopts the mode of casing pipe hole forming to construct, and normally used casing inner diameter is 135mm, and anchor rod body passes through from sleeve pipe, and the diameter of expanding reach part can reach 800～2000mm usually.
A kind of recoverable anchor rod has also appearred recently, as being in the Chinese invention patent of ZL200610061974.6 in the patent No., the inventor has proposed a kind of body of rod revolution anchor pole, comprise that revolution is placed on the interior body of rod of anchor hole, described body of rod termination places outside the anchor hole, straightway is located at the free section of anchor hole, meander sections places the anchor hole anchoring section, the described body of rod constitutes meander sections by its middle part doubling, two terminations all place outside the anchor hole, on the described meander sections body of rod, are provided with and can do distortion so that the body of rod reclaims the holder part of slippage when pulling out according to the revolution form, this holder part the time is poured into interior the injecting cement paste of anchor hole with construction and combines, and the supporting body of axis force of anchor is born in formation.Described holder part can be the deformable member that is positioned over body of rod meander sections inboard; Or be netted sleeve for driving the elastic component of body of rod meander sections expansion, also can be the reticular component of being located at body of rod meander sections surface or resilient sleeve with holes or sidewall, also can be and twine and the circular boop shape or the helical form member on body of rod meander sections surface.
This body of rod revolution anchor pole can produce following problem in actual mechanical process: the free section diameter that the body of rod passes through is less, be generally 135mm, therefore contact with the anchor hole wall when asking the part band the body of rod and can produce bigger frictional resistance and cause it to be difficult to by, construction inconvenience by free section.
