Abstract
The utility model provides a central hole double-face target of an observation point for a whole station apparatus, which is used as a burying piece of the observation point to be matched with the whole station apparatus to carry out displacement monitoring. The utility model is mainly composed of a metal base plate, reflecting films, a target center hole, target circle patterns, expansion bolts, wherein, the reflecting films are pasted on both sides of the metal base plate; the target circle patterns on the front and the back reflecting films are symmetrical by the metal base plate, and the center of the target circle patterns falls on the target center hole; the centers of the target circle patterns on both sides of the reflecting films are connected through the target center hole. The utility model not only can be installed in an underground tunnel and a cave depot, but also can be installed on any outdoor building and facility. The utility model provides a burying installation device which is suitable to be used in a large amount and has the advantages of good observation effect and low cost. The utility model is particularly suitable to be used for monitoring of the deformation of surrounding rock during the construction period of the underground tunnel and the cave depot.
Description
The utility model measuring point mesopore two plane type target is applicable to the various displacement measurements of total powerstation as observation instrument.
As the total powerstation object of observation, optimal measuring point reflex reflector is a prism at present.Prism has the advantage that precision height, reflecting properties are good, can penetrate distance.But, because prism costs an arm and a leg, general only be adapted at counting less, the reusable and occasion being convenient to load and unload, for resembling occasion such as surrouding rock deformation monitoring in construction of underground tunnel, what need in a large number is that the observation station of another kind of type is provided with mark, and this target designs for adapting to these class needs.
The purpose of this utility model provides a kind of total powerstation observation station mesopore two plane type target.This target is made up of metal base plate, reflective membrane, target center hole, scoring ring loop graph case, expansion bolt, and it is a kind of a large amount of uses, observation effect is good, cost price is low embedded device of being suitable for.
The purpose of the utility model target is achieved in that when the light that sends when total powerstation is mapped to this target that it can reflect back light by the incident direction, so that the observer can accurately make total powerstation to the distance and bearing between this target target center position.According to the difference between the data that successively measure for twice, can calculate target and bury some displacement of generation between twice observation constantly underground.The mark that is provided with as observation station, this target can be arranged at the various positions that subterranean tunnel, cave depot need be observed displacement, also can be arranged on any open-air buildings and the facility, be a kind of a large amount of uses, observation effect is good, cost price is low embedded device of being suitable for, be particularly suitable for using in subterranean tunnel and the surrouding rock deformation monitoring of cave depot construction time.Because it can observe from the pros and cons, and unified the position of observation station, improved the precision of observation by the target center hole.
Below in conjunction with accompanying drawing the utility model target is described further.
Fig. 1 is the target front view (FV).
Fig. 2 is the target outboard profile.
As shown in FIG.: mesopore two plane type target mainly is made up of full genus base plate 1, reflective membrane 2, target center hole 3, scoring ring loop graph case 4, expansion bolt 5.Metal base plate is the skeleton of target, and it has rational thickness, has both guaranteed that target has reliable rigidity, can carry out necessary shape adjustments according to observation angle when burying underground again.Reflective membrane sticks on the metal base plate both sides securely, can be from former and later two direction observations.Scoring ring loop graph case on the reflective membrane of front and back is with the metal base plate symmetry, and its center is dropped on the target center hole, and the scoring ring loop graph case center on the reflective membrane of base plate both sides connects by the target center hole.Reflective membrane has the performance of good orienting reflex light, can be fit to the requirement of total powerstation observation.Expansion bolt firmly fixes with metal base plate is in the same place, and target relies on expansion bolt to be fixed on the position that need bury target underground, and it also can be used alternate manner instead and be fixed on the position that needs, as passing through welding, bonding etc.During installation, it is very convenient to adjust angle and direction.
This label has following advantage:
It has the accuracy of observation that satisfies the requirement of common engineering construction monitoring, is cooperating suitable model Behind the total powerstation, the displacement observation precision can reach 1mm;
It has good light orienting reflex performance;
This target is cheap, can adapt to the needs of burying underground in a large number.Even built-in fitting does not reclaim, can not cause big economic loss yet.
