Abstract
The utility model is related to a kind of prefabricated pile of embedded concrete strain gauge to include pile body, sets hole slot on the lateral wall of pile body, and wooden unit is filled with hole slot;The madial wall of pile body is tiltedly installed with a threading hole, and the lower end of threading hole is connected with hole slot;It is set with threading hole in stainless steel tube, stainless steel tube filled with clay layer.The utility model is convenient that strain gauge is fixed in pile body by reserving hole slot, is passed the wire of strain gauge by threading hole, facilitates the detection and transmission of signal, the convenient detection to prefabricated pile Stress property and deformation degree.
Description
Technical field
The utility model belongs to technical field of building construction, more particularly to a kind of prefabricated pile of embedded concrete strain gauge.
Background technology
With reform and opening-up and the development of economic construction, prestressed concrete pipe pile starts to be widely used in Railway System,
And it is expanded to the fields such as industry and civil buildings, municipal administration, metallurgy, harbour, highway.
At present, prestressed high strength tubular is made using centrifugal rotation method, and through high-temperature steam curing, it is pre-buried in stake processed
Concrete strain gauge is difficult to, and the Stress property of pile tube can not be detected well, easily cause accident resulting from poor quality of projects, be deposited
In larger hidden danger.
The content of the invention
The utility model is all using centrifugal rotation legal system to solve prestressed high strength tubular present in known technology
Make, and through high-temperature steam curing, in stake processed, pre-buried concrete strain gauge is difficult to, the Stress property of pile tube can not be obtained well
Detection, easily cause accident resulting from poor quality of projects, there is larger potential problem and provide a kind of simple structure, it is easy to install,
Improve the prefabricated pile of the embedded concrete strain gauge of operating efficiency.
The utility model is adopted the technical scheme that to solve technical problem present in known technology:
The prefabricated pile of the embedded concrete strain gauge includes pile body, and filling in hole slot, hole slot is set on the lateral wall of pile body
There is wooden unit;
The madial wall of pile body is tiltedly installed with a threading hole, and the lower end of threading hole is connected with hole slot;Suit in threading hole
Have in stainless steel tube, stainless steel tube filled with clay layer.
Further, described hole slot uses the square hole slot of 200mm × 50mm.
Further, the axis of described threading hole and the angle of horizontal plane are 30 °
The utility model is convenient that strain gauge is fixed in pile body by reserving hole slot, by threading hole by strain gauge
Wire is passed, and facilitates the detection and transmission of signal, the convenient detection to prefabricated pile Stress property and deformation degree.
Brief description of the drawings
Fig. 1 is the structural representation of the prefabricated pile of the embedded concrete strain gauge that the utility model embodiment is provided;
Fig. 2 is the sectional view at the prefabricated pile 1-1 of the embedded concrete strain gauge that the utility model embodiment is provided;
In figure:1st, pile body;2nd, wooden unit;3rd, hole slot;4th, threading hole.
Specific embodiment
For the content of the invention of the present utility model, feature and effect can be further appreciated that, following examples are hereby enumerated, and coordinate
Accompanying drawing describes in detail as follows.
Structure of the present utility model is explained in detail with reference to Fig. 1, Fig. 2.
When prefabricated pile makes, in the square hole slot 3 of the reserved 200mm × 50mm in the outside of pile body 1, hole slot 3 is with correspondingly sized
Wooden unit 2 fill.Threading hole 4 is reserved in one end of hole slot 3, threading hole 4 makes of sizeable stainless steel tube.For the ease of
Threading, threading hole 4 is preferably inclined upwardly 30 degree or so, leads directly to pile tube endoporus.In addition, in order to prevent threading hole 4 from being mixed in stake processed
Solidifying soil is blocked, and the two ends of threading hole 4 are filled up using clay.
After the prefabricated pile made transports to test site, filling in the wooden unit 2 and threading hole 4 in reserved hole slot 3 is first removed
Thing clay layer, hole slot 3 is cleaned up, and concrete strain gauge, the side of concrete strain gauge are installed in it after hole slot 3 is dried
To that then must fill preformed groove with using ' epoxy resin mortar ' with the diameter parallel of pile tube, epoxy resin mortar mainly includes
Epoxy resin, dibutylester, ethylenediamine, cement and the dry sand without shale etc..Epoxy resin mortar has that adhesive force is strong, cohesive force
High the characteristics of, epoxy resin mortar exceedes the self-strength of concrete with the adhesion strength of concrete, and its failure mechanics does not occur
On adhesive surface, therefore epoxy resin mortar can be with concrete compatible deformation.
It is protection prefabricated pile inside conductor, protection shoe, concrete strain gauge during piling need to be set in prefabricated pile bottom
Wire first from positioned at the end of prefabricated hole slot 3 threading hole 4 introduce pile body 1 inside, after pile crown draw.Due to strain gauge
Part wire is stayed in outside pile body 1, if taking no action to, piling machine tup shock pile crown is inherently damaged and led during piling
Line, in order to avoid such case occurs, and is protected by with pile cover.Wire is passed from pile cover side before piling, then by stake
Cap sleeve is on tubular pile head, then starts piling.After the completion of pile sinking, strain gauge is measured, it is found that 4 test pile pile bodies 1 are buried
Strain gauge survival rate all more than 90%.
The above is only, to preferred embodiment of the present utility model, not to make any formal to the utility model
Limitation, it is every according to technical spirit of the present utility model to any simple modification made for any of the above embodiments, equivalent variations with
Modification, belongs in the range of technical solutions of the utility model.
