Description
Technical field
The utility model relates to a kind of observation pier that can be stealthy, more particularly, to engineering surveys, the observation of engineering monitoring
Pier is particularly suitable for the concrete condition of Deformation Control Net, construction control network and geodesic survey deformation monitoring.
Background technique
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, and observation pier gos 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 insole board, middle part
Pier body is generally platform shape square up and down, also there is square column type and cylinder, and special circumstances 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 fixed in ground or construction of structures.
Observation pier is the punctuate form that current engineering survey, engineering monitoring generally use, and structure is simple, cheap, but
There are still deficiencies under special circumstances, first is that being easily destroyed in the case where construction interference is big, Construction traffic and machinery break sight
Surveying pier is universal phenomenon；Second is that artificial destruction is also universal phenomenon；Third is that it is overall beautiful to influence engineering works.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of observation pier that can be stealthy, is meeting what observation needed
Meanwhile the shortcomings that avoiding existing observation pier.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is as follows:
A kind of observation pier that can be stealthy, including the pier body that N section diameter is sequentially reduced, each section pier body is vertically arranged；By diameter
Descending sequence sequence, preceding N-1 section pier body are hollow cylindrical configuration, and M section pier body can be accommodated in M-1 section pier body；
The top that M-1 saves pier body is equipped with internal screw thread, and the bottom end that M saves pier body is equipped with matched outer with the internal screw thread of M-1 section pier body
Screw thread, the path of the internal screw thread save the outer diameter of pier body not less than M；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 screw thread of previous section pier body
It connects, to realize relatively fixed；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 successively later section pier body need to be screwed into previous section pier body, it can be hidden by observation pier
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 that M saves pier body is sealed by circular bottom plate, and the diameter of the circular bottom plate is greater than the interior of M-1 section pier body
The path of screw thread and no more than the internal diameter of M-1 section pier body, in this way, conveniently detachable, prevented also from M-1 section pier body 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 body is fixed with internal lining pipe, and the internal screw 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 body
It connects.
The measuring platform include be fixed on N section pier body to insole board, it is described that locker is equipped with to insole board
The centering screw hole being overlapped with central axis with the central axis of pier body, 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 screw thread, the second pier
The bottom end of body, which is equipped with, is not less than the outer of the second pier body with matched first external screw thread of the first internal screw thread, the path of the first internal screw thread
Diameter；The top of the second pier body is equipped with the second internal screw thread, and the bottom end of third pier body is equipped with and the second internal screw thread matched second
External screw thread, the path of the second internal screw 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.
It, can be first in target position excavation pit, as required when the observation pier of the utility model is installed to target position
Armored concrete is backfilled, by observation pier entirety Transducers Embedded in Concrete when backfill, is needed to pay attention to when embedded so that observation pier is integrally hung down
Directly in ground, it is preferable that so that observation countertop is concordant with ground；For burying observation pier on molded concrete structure,
It can drill on target position, positioned vertical observation pier and keeping backfills again in concordant with the ground situation in top or slip casting, makes to see
Surveying pier and concrete structure becomes whole.
Compared with prior art, the beneficial effects of the utility model are as follows:
(1) the observation pier principle of the utility model is simple, and pipe screw thread interconnection technique is used between each pier body, ensure that every time
The repeatability of measuring platform position, it is ensured that the precision of observation pier；
(2) the observation pier protective value of the utility model is good, does not destroy vulnerable to external force；
(3) observation pier of the utility model can realize whole stealth in non-working condition, and it is whole not influence monitoring construction of structures
Body is beautiful.
