Description
Technical field
The present invention relates to a kind of observation pier that can be stealthy, more particularly, to engineering survey, engineering monitoring observation pier, especially
It is suitable for Deformation Control Net, the concrete conditions of construction control network and geodesic survey deformation monitoring.
Background technology
Under prior art conditions, engineering survey, the Deformation Control Net of engineering monitoring, construction control network and deformation monitoring institute
Observation pier usually uses armored concrete observation pier, observation pier to go deep into stability fundamental as monitoring point or measurement point, correlation rule
Model also specifies that the structure and Outside Dimensions of observation pier, structure are usually bottom deeply basis, and top is installed to bottom plate, middle part
Pier body is generally platform shape square up and down, also has square column type and cylinder, special circumstances to use steel pipe mark or double-layer pipe mark, pier
Body ground level is usually 1.2m, is to consider that the height of sighting line after installing instruments and average human eye height are almost the same, regardless of assorted
Form is all integrally fixed in ground or construction of structures.
Observation pier is the punctuate form that current engineering survey, engineering monitoring generally use, simple in structure, cheap, but
There are still deficiencies under special circumstances, first, being easily destroyed in the case where construction interference is big, Construction traffic and machinery break sight
It is universal phenomenon to survey pier；Second is that artificial destruction is also universal phenomenon；Third, it is overall beautiful to influence engineering works.
Invention content
In view of the deficiencies of the prior art, the present invention provides a kind of observation pier that can be stealthy, while satisfaction observation needs,
The shortcomings that avoiding existing observation pier.
In order to solve the above-mentioned technical problem, technical scheme is as follows：
A kind of observation pier that can be stealthy, including N save the pier body that diameter is sequentially reduced, and each section pier body is vertically arranged；By diameter by big
It sorts to small sequence, preceding N-1 sections pier body is hollow cylindrical configuration, and M section pier bodies can be accommodated in M-1 section pier bodies；M-1
The top for saving pier body is equipped with internal thread, and the bottom end that M saves pier body is equipped with the matched external screw thread of internal thread that pier body is saved with M-1,
Outer diameter of the path of the internal thread not less than M section pier bodies；The top that N saves pier body is equipped with measuring platform；
When work, each adjacent pier body passes sequentially through threaded connection；
Wherein, N, M are the integer not less than 2, and M≤N.
In this way, adjacent pier body can realize that screw thread connects by the external screw thread of later section pier body and the internal thread of previous section pier body
It connects, is relatively fixed to realize；Each section pier body, which passes sequentially through, to be screwed to form vertical stable whole pier structure, can meet sight
Survey demand；When without using observation pier, only later section pier body need to be screwed into previous section pier body successively, you can observation pier is hidden
The aboveground space for concealing or substantially reducing observation pier occupancy, prevents observation pier by damage, can also promote observation pier installation
The overall aesthetic degree of position building.
M section pier body on offers reinforcing hole, in this way, can by extension bar be inserted into reinforcing hole in, facilitate pier body precession or
It screws out.
The bottom end of M section pier bodies is sealed by circular bottom plate, and the diameter of the circular bottom plate is more than the interior of M-1 section pier bodies
The path of screw thread and no more than the internal diameter of M-1 section pier bodies, in this way, conveniently detachable, prevented also from M-1 section pier bodies it is unexpected from
M saves abjection in pier body；It can also be used for the final position for assisting determining measuring platform.
The inner wall top of M-1 section pier bodies is fixed with internal lining pipe, and the internal thread is set on internal lining pipe；M saves pier body
Outer wall bottom end be equipped with outer liner tube, the external screw thread is set on outer liner tube.In this way, the storage between adjacent pier body can be facilitated.
Further, the internal lining pipe and M-1 save pier body integrally connected, and the outer liner tube integrally connects with M section pier bodies
It connects.
The measuring platform include be fixed on N section pier bodies to bottom plate, it is described that locker is equipped with to bottom plate
The centering screw hole overlapped with the central axis of pier body with central axis, to facilitate the installation of observation utensil.
The observation pier includes the first pier body, the second pier body and that diameter is sequentially reduced in one of the embodiments,
Three pier bodies, the first pier body, the second pier body are hollow cylindrical configuration, and the top of the first pier body is equipped with the first internal thread, the second pier
The bottom end of body is equipped with is not less than the outer of the second pier body with matched first external screw thread of the first internal thread, the path of the first internal thread
Diameter；The top of the second pier body is equipped with the second internal thread, and the bottom end of third pier body is equipped with and the second internal thread matched second
External screw thread, the path of the second internal thread are not less than the outer diameter of third pier body；The measuring platform is set to the top of third pier body.
Be respectively equipped on the second pier body and third pier body in one of the embodiments, the first reinforcing hole and second plus
Power hole.
When the observation pier of the present invention is installed to target location, can as required be backfilled first in target location excavation pit
Armored concrete, when backfill in observation pier entirety Transducers Embedded in Concrete, will be needed to pay attention to when embedded so that observation pier it is whole perpendicular to
Ground, it is preferable that so that observation countertop is concordant with ground；It, can be for burying observation pier on molded concrete structure
It drills on target location, positioned vertical observation pier and keeps backfilling again or slip casting in the case of top is concordant with ground, make observation pier
It is integrally formed with concrete structure.
Compared with prior art, beneficial effects of the present invention are as follows：
（1）The observation pier principle of the present invention is simple, and pipe screw thread interconnection technique is used between each pier body, ensure that each measuring platform position
The repeatability set, it is ensured that the precision of observation pier；
（2）The observation pier protective value of the present invention is good, is not easy to be destroyed by external force；
（3）The observation pier of the present invention can realize whole stealth in non-working condition, and it is overall beautiful not influence monitoring construction of structures.
