Abstract
The present invention provides a kind of field surface observation pier structure, including steel pipe and joint bar, among side slope that the insertion of the lower end of joint bar is observed, rock mass, steel pipe socket is set to the top of joint bar, and concrete has been poured in steel pipe, forced centering base is installed at the concrete of steel pipe upper end.It is larger to solve existing observation pier volume, and the problem that production process is relatively complicated.Belong to hydraulic and hydroelectric engineering building monitoring facilities technical field.
Description
Technical field
The present invention relates to a kind of field surfaces to observe pier structure, belongs to hydraulic and hydroelectric engineering building monitoring facilities technology neck
Domain.
Background technique
Safety monitoring design has a decisive role in hydraulic and hydroelectric engineering construction period and runtime, extremely important.
Safety monitoring design can not only play the role of guiding construction, feedback and verifying design to engineering, moreover it is possible to grasp and monitor work
The operating status of journey, to ensure that engineering safety operation provides valid data.Surface deformation monitoring is in project security monitoring design
A considerable content, Observation principle be by the way that a series of surface observation pier is arranged on building or side slope surface,
Using equipment such as total station, theodolite, rangefinders, the sighting targets such as prism, the surveyor's beacon being erected in observation pier top are surveyed
It reads, the change in displacement of observation pier periods a series of is obtained, to monitor the surface deformation situation of building or side slope.
Traditional observation pier volume is larger, and production process is relatively complicated, concrete operations process are as follows: assembling reinforcement, formwork erection
The five big key steps such as plate, casting concrete, disassembly template, swabbing.In addition, in actual use, observation pier appearance
Face drenches with rain by exposing to the weather, and the coating on surface is easy to fall off, fades, and permanent observation pier surface later is very unsightly.Traditional
There is inconveniences for use under field, the environment that condition is arduous, inconvenient for surface observation pier.
Summary of the invention
It is an object of the invention to: a kind of field surface observation pier structure is provided, it is larger to solve existing observation pier volume,
And the problem that production process is relatively complicated.
To solve the above problems, pier structure, including steel pipe and joint bar are observed in such a field surface of proposed adoption, joint bar
Side slope that lower end insertion is observed, among rock mass, steel pipe socket is set to the top of joint bar, and concrete has been poured in steel pipe, steel pipe
Forced centering base is installed at the concrete of upper end.
In aforementioned observed pier structure, the joint bar is fourJoint bar, four root cutting muscle squarely quadrangles are distributed in steel pipe
It is interior；
In aforementioned observed pier structure, the steel pipe isSteel pipe.
Compared with prior art, the present invention improves existing traditional surface observation pier structure, optimizes structural style,
Simplify production process, a kind of novel surface observation pier structural shape is provided, convenient for arduous, unhandy in field, condition
Under environment, surface observation pier can quickly, be easily formed, the time is saved, improves efficiency.
Detailed description of the invention
Fig. 1 is the schematic diagram of the section structure of the invention；
Fig. 2 is the cross sectional view of Fig. 1 institute steel tube observation pier；
Fig. 3 is the top view of steel pipe observation pier in Fig. 1.
Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with embodiment to skill of the invention
Art scheme is clearly and completely described, it is clear that the described embodiment is only a part of the embodiment of the present invention, rather than complete
The embodiment in portion, based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, shall fall within the protection scope of the present invention.
Embodiment:
Referring to attached drawing 1 to Fig. 3, the present embodiment provides a kind of field surfaces to observe pier structure, with high unboiled water power station BT3 accumulation
For body is to existing conventional surface observation the renovating of pier structure, it is attached that Gao Shengshui power plant project BT3 accumulation body is in big ferry
Close flood cross a river right bank, apart from engineering dam site linear distance about 7.3km, specific modification scheme be use a diameter for
The steel pipe 1 of left and right is used as observation pier main structure, with four between steel pipe 1 and the side slope being observed, rock massJoint bar 2
Connection, then the fill concrete 3 in steel pipe 1, installs forced centering base 4 in steel pipe top in 3 not yet final set of concrete,
Finally to 3 final set of concrete after, steel pipe observation pier i.e. ultimately form.
The above embodiments are only used to illustrate and not limit the technical solutions of the present invention, although referring to above-described embodiment to this hair
It is bright to be described in detail, it will be apparent to an ordinarily skilled person in the art that: still the present invention can be modified or be waited
With replacement, without departing from the spirit or scope of the invention, or any substitutions, should all cover in power of the invention
In sharp claimed range.
