Abstract
The utility model provides a concealed forced-centering observation target, comprising a target rod, a forced-centering target core, an observation target, and a target core cap, wherein the upper portion of the target rod is a quick coupling, and the lower portion is provided with external threads; one end of the forced-centering target core is provided with internal threads that are matched with the external threads of the target rod so as to connect the forced-centering target core and the target rod; one end of the observation target is provided with a quick joint that is connected with the quick coupling of the target rod; and the target core cap is provided with external threads that are matched with the internal threads of the forced-centering target core to screw the target core cap on the forced-centering target core. By adopting said structure, it is possible to make the center of the target and the monitoring point in level or plumb line without the need of tripod so as to prevent leveling error, centering error, and the like.
Description
Technical field
The utility model relates to a kind of measurement mechanism, relates in particular to a kind of device that is used for deformation observation of structure.
Background technology
In harbour, important building construction period and after building up,, need regularly carry out deformation observation in order to understand whether produce situations such as sedimentation, displacement at any time.
The deformation observation reference point generally is located at the rear of harbour, the observation pier of having ready conditions here forced centering being set.And observation station generally is located in harbour angle and each segmentation, and the observation pier of forced centering often can not be set on these aspects.Conventional working method is: need survey signal is placed on the tripod when observation, operating personnel make the center of surveyor's beacon and monitoring point by flattening (level adjustment), plumb bob on same pedal line to medium operation.
Because in leveling, to medium operating process; Personnel's operative skill, the factors such as instability of tripod all can produce all kinds of errors, thereby have influence on the precision and the construction quality of deformation observation, and this problem is perplexing the surveying and mapping technology personnel all the time.
Therefore, technical field of mapping exists such demand: invent a kind of hidden forced centering survey signal that uses on all kinds of monitoring points, change traditional mode of operation, make accuracy of observation not be subjected to the influence of various labile factors.
Summary of the invention
For satisfying as above demand, the utility model provides a kind of hidden forced centering survey signal, and its technical scheme that adopts is as follows:
A kind of hidden forced centering survey signal is characterized in that, comprising:
Mark post, the top of this mark post are rapid-acting coupling, and the bottom is an external thread;
Forced centering mark core, the one end is an internal thread, this internal thread cooperates with the external thread of this mark post, and this forced centering mark core is connected with this mark post;
The observation surveyor's beacon, the one end has fast interface, and this fast interface is connected with the rapid-acting coupling of this mark post;
Mark core cap has external thread, and this external thread matches with the internal thread of this forced centering mark core, should mark the core cap and be tightened on this forced centering mark core.
The utility model has the advantages that:
1. because surveyor's beacon of the present utility model is an implicit expression, it is normally runed without any influence harbour etc.
2. implicit expression surveyor's beacon forced centering does not need tripod, and the center of surveyor's beacon and monitoring point are in together on level, the pedal line, avoids leveling, centering equal error.
Description of drawings
Below in conjunction with accompanying drawing,, will make the technical solution of the utility model and other beneficial effects apparent by detailed description to embodiment of the present utility model.
Fig. 1 is a synoptic diagram of the present utility model;
Fig. 2 is that each parts of the present utility model are dissected synoptic diagram.
Embodiment
In order further to understand feature of the present utility model, see also following about detailed description of the present utility model and accompanying drawing, yet appended graphic only provide with reference to the usefulness of explanation, be not to be used for protection domain of the present utility model is limited.
As shown in Figure 1, be an embodiment of the present utility model.Hidden forced centering survey signal of the present utility model is made up of 4 parts, mark post 101, mark core cap 102, forced centering mark core 103 and observation surveyor's beacon 104.
As Fig. 2 is that each parts of the present utility model are dissected diagram.Illustrate the annexation of each parts of the utility model as can be seen by this.The top of mark post 101 is rapid-acting coupling 201, and it is a universal standard public access mouth, and this rapid-acting coupling is connected with the interface 204 of observation surveyor's beacon 104.The bottom of mark post 101 is an external thread 205, and this external thread 205 cooperates with the internal thread 203 of an end of forced centering mark core 103, to connect mark post 101 and forced centering mark core 103.Mark core cap 102 is an external thread, and it also cooperates with the internal thread 203 of forced centering mark core 103, is used for stoping entering of foreign material being tightened under the obsolete state of the utility model on the forced centering mark core 103, guarantees that forced centering mark core 103 does not damage.
According to the technical requirement of deformation observation, imbed forced centering mark core 103 in advance in the position of needs observation, concrete grammar is:
1. select and the identical drill bit of forced centering mark core 103 diameters, at the observation station vertical drilling, the about 20MM of hole depth.
2. use hammer gently hammer stem forced centering mark core 103 is embedded in the boring, until forced centering mark core 103 surfaces and logical place of terrace and levels.
3. forced centering mark core 103 is done and forced the thoughts of returning home to be handled, screw on mark core cap 102 afterwards.
4. when observing, the mark core cap 102 of outwarding winding screws in mark post 101 in the forced centerings mark cores 103.
5. observation surveyor's beacon 104 is installed, in order to deformation observation at mark post 101 tops.
6. after observation finishes, screw out mark post 101, screw in mark core cap 102 again, make forced centering mark core 103, mark core cap 102 be in hidden state.
The utility model can be used for the displacement observation of basic points such as deformation observation, landslide detection, the foundation of accurate control net.When not needing to observe at ordinary times, forced centering mark core 103 has been imbedded underground and forced centering in advance, screws in mark core cap 102 on the forced centering mark core 103, has prevented that foreign material from falling in the forced centering mark core 103.When observation, the mark core cap 102 of outwarding winding by last observation surveyor's beacon 104, mark post 101, can be observed.Owing to replaced conventional tripod to set up, artificial leveling, to the mode of operation of medium operation, thus further improved construction quality and precision.And forced centering mark core 103 imbeds undergroundly, can not influence ground normal business activities.
Should be understood that; above-mentioned detailed description to embodiment is only in order to understand the utility model; for those of ordinary skills; can be improved according to the above description or conversion, so long as reach all improvement of this purpose and the protection domain that conversion all should belong to the utility model claims.
