Technical field
The utility model relates to the Geotechnical Engineering field, especially a kind of counterforce device that is used for face of land rock mass original position deformation test.
Background technology
In the Geotechnical Engineering field, when distortion makes an experiment to the original position of face of land rock mass, need build corresponding counter-force platform usually; And the counter-force platform needs counterforce device to provide counter-force to support, and several kinds of modes below the existing counterforce device that is used for face of land rock mass original position deformation test adopts usually: first kind of mode is the special exploration adit of excavation, utilizes the hole wall of exploration adit to provide counter-force to support; Though this mode counter-force is effective; But the excavation required time of exploration adit is longer, generally; Test needs nearly one month time from beginning to accomplish; Test period is longer, has satisfied not the duration schedule requirement of engineering, can't reach the purpose of fast detecting face of land rock mass original position distortion.The second way is on rock mass, to hole, and in the hole, places deformed bar drag pull bar, with high-grade concrete deformed bar drag pull bar is cast in the rock mass hole then; Installation test equipment again behind the concrete curing; Imposed load is also measured the distortion of rock mass, though this mode easy construction; Concrete curing enhancing needs nearly one month time; Test period is longer, has also satisfied not the duration schedule requirement of engineering, can't reach the purpose of fast detecting face of land rock mass original position distortion.The third mode is to adopt the mode of preloading, thereby promptly utilizes hanging device shipment sandbag and pour into a mould formation counter-force platform with mass concrete, and this mode still need be built the concrete block of big volume; And the concreting curing time is longer; Cause the test period longer, satisfied not the duration schedule requirement of engineering equally, can't reach the purpose of fast detecting face of land rock mass original position distortion; And the counter-force platform of preloading collapses easily in process of the test, causes security incident.
The utility model content
The utility model technical matters to be solved provides a kind of counterforce device that is used for face of land rock mass original position deformation test that can realize fast detecting.
The utility model solves the technical scheme that its technical matters adopted: this is used for the counterforce device of face of land rock mass original position deformation test; Comprise anchor tie; Said anchor tie lower end is fixedly connected with lower cone, and the power transmission cover that on anchor tie, is arranged with expansion sleeve and is used for exerting pressure to expansion sleeve, the small end of said lower cone insert in the expansion sleeve; Anchor tie is provided with the block that can move along anchor tie, and the upper end of power transmission cover withstands on the block.
Further be, be arranged with upper cone on the said anchor tie, and upper cone is between expansion sleeve and power transmission cover, the small end of said upper cone inserts in the expansion sleeve, and the big end end face of upper cone contacts with the lower surface that power transmission is overlapped.
Further be, said block is a nut, and nut and anchor tie are through being threaded.
Further be that the inwall at said expansion sleeve two ends is provided with and the suitable inclined-plane of the conical surface of upper cone or lower cone.
The beneficial effect of the utility model is: this counterforce device only needs counterforce device is put into the good hole of brill on rock mass in advance when mounted, block is moved down, and then through the power transmission cover expansion sleeve is moved downward; Expansion sleeve moves downward the displacement that makes lower cone insert expansion sleeve to be increased, thereby expansion sleeve is expanded, and expansion sleeve compresses the rock mass hole wall after expanding; And then provide counter-force to support, and whole counterforce device is installed very convenient, and the required set-up time is shorter; Make entire test only need just can accomplish in six days, shortened the test period greatly, satisfied the duration schedule requirement of engineering; Reach the purpose of fast detecting face of land rock mass original position distortion; In addition, this counterforce device counter-force is effective, and security is higher.Between expansion sleeve and power transmission cover, upper cone is set, can increases the expansion effect of expansion sleeve, and then improve the effect that counter-force supports.Adopt nut as block, can realize moving of block very easily, operation is very easy.The suitable inclined-plane of the conical surface of setting and upper cone or lower cone on the inwall at expansion sleeve two ends is in order to make in the easier insertion expansion sleeve of upper cone or lower cone.
Description of drawings
Fig. 1 is the structural representation that the utility model is used for the counterforce device of face of land rock mass original position deformation test;
Description of symbols among the figure: anchor tie 1, lower cone 2, expansion sleeve 3, power transmission cover 4, block 5, upper cone 6.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
As shown in Figure 1; The counterforce device that this is used for face of land rock mass original position deformation test comprises anchor tie 1, and said anchor tie 1 lower end is fixedly connected with lower cone 2; The power transmission cover 4 that on anchor tie 1, is arranged with expansion sleeve 3 and is used for exerting pressure to expansion sleeve 3; The small end of said lower cone 2 inserts in the expansion sleeve 3, and anchor tie 1 is provided with the block 5 that can move along anchor tie 1, and the upper end of power transmission cover 4 withstands on the block 5.This counterforce device only needs counterforce device is put into the good hole of brill on rock mass in advance when mounted, block 5 is moved down, and then through power transmission cover 4 expansion sleeve 3 is moved downward; Expansion sleeve 3 moves downward the displacement that makes lower cone 2 insert expansion sleeve 3 to be increased, thereby expansion sleeve 3 is expanded, and compresses the rock mass hole wall after expansion sleeve 3 expands; And then provide counter-force to support, and whole counterforce device is installed very convenient, and the required set-up time is shorter; Make entire test only need just can accomplish in six days, shortened the test period greatly, satisfied the duration schedule requirement of engineering; Reach the purpose of fast detecting face of land rock mass original position distortion; In addition, this counterforce device counter-force is effective, and security is higher.
