Abstract
A forced centering device comprises a rod piece and a centering connecting component, wherein one end of the centering connecting component is connected with the rod piece through threads, the end surface of the other end of the centering connecting component is a flat round surface, a round groove is formed in the center of the flat round surface, and an annular groove is formed in the centering connecting component. The technical scheme has the benefits as follows: the forced centering device can be applied to replace a conventional monitoring mark device, and defects of poor safety and accuracy of a conventional monitoring mark during monitoring are overcome.
Description
Technical field
The utility model relates to sedimentation and offset measurement field, relates in particular to a kind of forced centering apparatus of using for measuring sedimentation and horizontal shift.
Background technology
Along with the development of the engineering industries such as work China Democratic National Construction Association, mine, municipal administration, various complexity and large-scale engineering or construction of structures is increasing, the construction of engineering, has changed the original stress state in ground, and this just will inevitably cause Rock And Soil ground and the distortion on stratum around.Therefore need in engineering construction process, monitor ground and stratum.
In building construction process, conventionally need to monitor the horizontal shift of foundation ditch and vertical displacement.In observation process, traditional pit retaining monitoring designation equipment generally adopts monitoring railway spike, phillips driver, monitoring nailing or little steel nail etc.; Erection method general employing in monitoring point is set up the leveling of tripod centering and is sighted for instrument, sets up to put in a pole pair to flatten for sighting, and hand steered little prism bar is sighted for instrument.
Traditional monitoring and erection method have some limitations, and the limitation of for example setting up tripod is cannot set up tripod under the wide not prerequisite of flange, and process and the time of centering leveling are simultaneously all longer, and people can not leave tripod, also safe not; Set up that to put the precision flattening in a pole pair low, easily flexural deformation of bar itself, affects measuring accuracy, and people can not, from opening point bar, exist certain potential safety hazard; Hand steered little prism, because do not have support not fix, easily rocks, and causes centering leveling all can not reach requirement, and people can not loose one's grip and leave a moment, also has certain potential safety hazard.
Summary of the invention
The utility model is for the deficiencies in the prior art, and a kind of for measuring the forced centering apparatus of sedimentation and horizontal shift, the application of this device, can solve the potential safety hazard existing in traditional monitoring process, makes measurement result more accurate simultaneously.
A kind of forced centering apparatus described in the utility model is made up of rod member and centering link, and one end of described centering link is connected with rod member by screw thread; The end face of the described centering link other end is smooth disc, and the circle centre position of described smooth disc is provided with circular groove, on described centering link, has a ring groove.
Further, described rod member is the Metallic rod with Telescopic.
Further, described forced centering apparatus also comprises a protective cover, and described protective cover is directly buckled on forced centering apparatus.
The beneficial effect of technical scheme described in the utility model is: the application of forced centering apparatus described in the utility model, can substitute traditional monitoring device for marking, and solve the poor stability that traditional monitoring mark exists in the time of monitoring, the defect that precision is not high.
Accompanying drawing explanation
A kind of forced centering apparatus structural representation of Fig. 1;
In figure: 1, rod member, 2, centering link, 3, circular groove, 4, annular groove.
Embodiment
As shown in Figure 1, a kind of forced centering apparatus described in the utility model is made up of rod member 1 and centering link 2, and one end of described centering link 2 is connected with rod member 1 by screw thread; The end face of described centering link 2 other ends is smooth disc, and the circle centre position of described smooth disc is provided with circular groove 3, has a ring groove 4 on described centering link 2.
In building construction process, after foundation ditch face is carried out, forced centering apparatus described in the utility model is embedded on foundation ditch face, described forced centering apparatus can be buried underground into ground arbitrarily angled as required.Certainly, best mode is that forced centering apparatus described in the utility model is vertically embedded in to side slope top and hat back portion as far as possible, bury about 30 centimeters of part underground, about 6 centimeters of exposed parts, while carrying out displacement monitoring, prism headgear can be observed on forced centering apparatus described in the utility model.
In addition, can as required, at forced centering apparatus described in the utility model, one protective cover be set outward, described protective cover is directly buckled on forced centering apparatus.Can effectively protect described forced centering apparatus to be subject to external influence and to produce distortion etc.; Meanwhile, can effectively prevent that workmen from bumping on described forced centering apparatus and security incident occurs.
Forced centering apparatus described in the utility model can effectively be eliminated the error of centralization, even vertically also do not affect when burying underground; It is fast that prism is enclosed within time on this device, is not also subject to limited space, simultaneously because observation person can observe away from forced centering apparatus, can effectively guarantee observation person's personal safety.
