Abstract
The utility model discloses a kind of Geodetic Surveying with easily finding triangulation pillar system, solving the problem that triangulation pillar pre-buried in surveying work is not easily found and accurately located.Comprise the pre-buried hole of markstone (9), huge rock (4) is provided with at the bottom of the hole in the pre-buried hole of markstone (9), huge rock (4) is provided with metalling (6), metalling (6) arranges pillar (2), pillar (2) is provided with back fill course (1), pillar (2) is fixedly installed high strength permanent magnet (3), the ground, top of back fill course (1) is provided with miniature Gauss magneto meter (8).The utility model execute-in-place method simple practical, can save Measuring Time, improves and measures efficiency.
Description
Technical field
The utility model relates to a kind of pre-buried mark of Geodetic Surveying, particularly a kind of triangulation pillar system easily found on the ground and locate.
Background technology
Geodetic Surveying is the one basic measurement method in advance in order to meet the basic measurement needs such as mine surveying, city planning, topographical surveying, engineering survey.Need in this measuring method at underground preburied triangulation pillar, to determine datum mark.Triangulation pillar pre-buried good after will as permanent mark point, as the reference point of later engineering survey.Triangulation pillar is generally wanted pre-buried and in measuring process afterwards, often be there will be the situation that can not find the pre-buried triangulation pillar of subsurface to subsurface 30-50 centimeters, surveying work cannot be launched in time, particularly particularly serious in Canal in Loess Area situation.
Summary of the invention
The utility model provides a kind of Geodetic Surveying with easily finding triangulation pillar system, solves the problem that triangulation pillar pre-buried in surveying work is not easily found and accurately located.
The utility model solves above technical matters by the following technical programs:
A kind of Geodetic Surveying is with easily finding triangulation pillar system, comprise the pre-buried hole of markstone, huge rock is provided with at the bottom of the hole in the pre-buried hole of markstone, huge rock is provided with metalling, metalling arranges pillar, pillar is provided with back fill course, pillar is fixedly installed high strength permanent magnet, the ground, top of back fill course is provided with miniature Gauss magneto meter.
Huge rock is provided with huge rock center mark point, pillar is provided with pillar center mark point, huge rock center mark point and pillar center mark point are arranged on the vertical vertical line of the same above-below direction vertical with day water horizontal line.
The beneficial effects of the utility model are, when using this trigpoint mark, can find its embedding place as soon as possible, execute-in-place method simple practical, can save Measuring Time, improve and measure efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail:
A kind of Geodetic Surveying is with easily finding triangulation pillar system, comprise the pre-buried hole 9 of markstone, huge rock 4 is provided with at the bottom of the hole in the pre-buried hole 9 of markstone, huge rock 4 is provided with metalling 6, metalling 6 arranges pillar 2, pillar 2 is provided with back fill course 1, pillar 2 is fixedly installed high strength permanent magnet 3, the ground, top of back fill course 1 is provided with miniature Gauss magneto meter 8.
Huge rock 4 is provided with huge rock center mark point 5, pillar 2 is provided with pillar center mark point 7, huge rock center mark point 5 and pillar center mark point 7 are arranged on the vertical vertical line of the same above-below direction vertical with day water horizontal line.
Just implanting the recognizates such as permanent magnet with during being cast from concrete triangulation pillar, the pre-buried markstone to underground is made to have magnetic.Detect the power checking magnetic during use with miniature Gauss magneto meter on the ground, the embedding place of markstone can be found according to the power of magnetic very soon, then, excavate rapidly the pre-buried hole of markstone, after exposing triangulation pillar, can follow-up surveying work be carried out.Triangulation pillar conventional in present survey engineering is generally by being cast from concrete, and pillar and the huge rock end face central authorities of triangulation pillar all embed a porcelain or metallic mark, and common metal is masked as copper or irony.
