Description
Technical field
It the utility model is related to the observation device in a kind of geodesic survey and geophysical observatory field, more particularly to a kind of use
In the simple observation pier of the GPS of high-precision distortion measurement.
Background technology
Currently used high-precision GNSS (GPS) observation pier, usually armored concrete, which pours, forms
Square column type or cylindrical pier body, generally under basement rock or soil layer environment excavate the certain size (size and project of length
Grade, choosing build environment etc. about) foundation pit, the concrete foundation of cylindricality is built into reinforcing bar, sand, cement etc., then in ground
On the cylindrical bodies observation pier of given size is poured using template, while stainless steel forced centering mark is embedded to pier body top surface,
Mark top will flush with observation pier top surface.Although this observation pier is with a high standard, easy to use, construction cost is higher, by
The engineering such as the construction materials such as substantial amounts of water, cement, yellow ground and generator, concrete mixer must be transported when building to set
Standby, in the by-place having inconvenient traffic, such as Qinghai-Tibet Platean or landform steep hills arteries and veins, the financial cost of construction can drastically increase,
Efficiency of construction is relatively low, and adds potential security risk to construction party；On the other hand, observation pier from be built into come into operation need
The time of more than one week is wanted, therefore urgent observation mission can not be applied to, such as earthquake emergency measurement etc..Others observation is flat
Platform, tripod is such as set up, it is not firm enough although fast, easily by high wind, precipitation, livestock and wild animal
Disturbed etc. factor so that observation data are unreliable, so it is difficult to competent be up to several weeks or continuous the measurement more than several months.
Utility model content
The utility model purpose is to be directed to weak point existing for existing observation technology, there is provided one kind is used for high-precision shape
Become the simple observation pier of GPS of measurement.
The utility model purpose is realized in：
The utility model is made up of firm banking, main cylinders and forced centering platform；
From bottom to top, screw thread is socketed successively for firm banking, main cylinders and forced centering platform.
Compared with conventional art, the utility model has advantages below and effect：
1. provide a kind of firm GNSS observation platforms of performance；
2. more than the low decades of times of construction cost, a people carries with instrument and can completed, and reduces labor intensity and economy
Cost.
3. can complete to lay within an hour, it can then come into operation immediately, especially suitable for appointing it is pressed for time
Business, emergent deformation monitoring and landslide monitoring after such as big shake.
In a word, the utility model is that a kind of observation for laying the GNSS measurements that simple and fast, cost are cheap, performance is firm is put down
Platform；Suitable for technical fields such as earthquake emergency measurement, crustal movement monitoring, dam and bridge deformation monitorings.
