Description
[technical field]
Measurement apparatus technical field is the utility model is related to, is specifically that one kind is used to measure seam structure on two sides thing difference in height
The measurement apparatus of value.
[background technology]
In current science of bridge building structure, to prevent that each part is heavy because uneven settlement of foundation causes destruction to set
Drop seam, for example the subsiding crack between retaining wall wall, also promising to prevent superstructure from producing second inner force because lifting warm deformation
Expansion joint is set, and for example respectively across bridge deck anti-collision wall and deck paving joint is respectively provided with expansion joint, above-mentioned subsiding crack, expansion joint
Deng can be collectively referred to as in seam, including work China Democratic National Construction Association structure, there is also similar seam.
Due to load actions such as congenital construction quality reason or posterior settlement, temperature, soil pressures, easily cause seam two
Side structure thing forms off normal, the discrepancy in elevation, and the size of the structure on two sides thing discrepancy in elevation directly reflects works technology status degree of injury, the discrepancy in elevation
Measurement and monitoring it is particularly critical.Existing vertical survey method often using general measuring methods such as straight steel ruler, horizon rules, makes
Limited with condition larger, and factor influences because the presence of center-line joint, works be uneven etc., cause substantial measurement errors compared with
Greatly, after some time it is possible to reach 1cm~2cm.
[utility model content]
The purpose of this utility model is exactly to solve above-mentioned weak point of the prior art, there is provided a kind of structure is new
The measurement apparatus for being used to measure seam structure on two sides thing height difference that is clever, safe and reliable, being convenient for measuring, including measurement pipe, company
Adapter, described measurement pipe include the first measurement pipe and the second measurement pipe, and the first measurement pipe and the second measurement pipe include one respectively
Has graduated transparent round tube, the bottom of transparent round tube is provided with conical probe, and the top of described transparent round tube, which is provided with one, to be had
The pipe cap of internal thread, correspondingly, there is the external screw thread matched with the internal thread at the top of transparent round tube, opened on the wall of pipe cap
Provided with a passage, the bottom of described transparent round tube is provided with connecting hole, and described connecting tube both ends connect the first measurement respectively
Connecting hole on pipe and the second measurement pipe, described connecting tube use flexible material.
Described connecting tube is transparent rubber connecting pipe.
Described transparent round tube is lucite hollow circular-tube.
Described pipe cap crown is provided with universal level bulb.
The utility model compared with the existing technology, the advantage is that the utility model for accurate also without energy in the market
Really, the equipment and instrument of the seam structure on two sides thing discrepancy in elevation are convenient for measuring, and design a kind of solution precision problem that can be good and
A kind of measurement apparatus of seam structure on two sides thing height difference easy to operation, maximum range 300mm, measurement accuracy 1mm.
The utility model adapts to the vertical survey in various occasions and complex environment, and operation is simple, survey measurements is convenient, data stabilization
Property it is fine, and precision is high.

[embodiment]
The utility model is described in further detail below in conjunction with the accompanying drawings, the structure and principle of this device people professional to this
For be very clear.It should be appreciated that specific embodiment described herein is only to explain the utility model, and do not have to
In restriction the utility model.
As shown in figure 1, the utility model is a kind of measurement apparatus of seam structure on two sides thing height difference, including two surveys
Buret and a transparent rubber connecting pipe.Measurement pipe includes organic glass hollow pipe and probe.As shown in Fig. 2 lucite
Hollow circular-tube is transparent, it is resistance to fall, be easy to reading, be carved with mm rank scales on outer wall, the total a height of 300mm of valid reading, lucite
Hollow circular-tube bottom surface is conical probe, and top surface is provided with a tapped pipe cap, a small ventilation of circle is provided with pipe cap wall
Hole, pipe cap crown are equipped with universal level bulb.Cathetometer is widely applicable, maximum range 300mm, precision 1mm.
When actually measurement work starts, it can inject into pipe that water etc. is coloured or colourless liquid from the circular hole on pipe cap wall
Body, you can start vertical survey.Two probes are individually positioned on the works of seam both sides, keep probe and works top surface
Vertically, level(l)ing bubble is placed in the middle, then after liquid is still in same liquid level in two probes, you can utilize the graduation mark on tube wall
Respectively reading obtain the first measurement pipe liquid level high 3 and the second measurement pipe liquid level it is high by 4, then the seam structure on two sides thing discrepancy in elevation is
The liquid level height of the second measurement pipe, measurement accuracy 1mm are subtracted for the liquid level height of the first measurement pipe.Measurement can push up probe after terminating
Facial canal cap backspin on earth, that is, closes probe pipe, prevents internal liquid from exosmosing, then storage is put well.
