Abstract
The utility model relates to an asphalt pavement paving depth measurement ruler and belongs to the field of measuring tool design. The asphalt pavement paving depth measurement ruler comprises a cone with a groove arranged at the axis. The top of the cone is provided with a handle. The axis of the cone is provided with a measuring chute. A measuring slide block horizontally passes through the measuring chute. Springs are vertically disposed at left and right sides of the measuring slide block. Upper ends of the springs press against the bottom of the handle, and lower ends of the springs press against the top of the measuring slide block. A measuring bar is vertically fixed to the middle part of the measuring slide block. The handle, corresponding to the measuring bar, is provided with a through hole. The measuring bar passes through the through hole, and the measuring bar is equipped with scales. When the thickness of an asphalt surface is measured, errors of measured thickness value can be effectively reduced. Under the action of the springs, the measuring slide block can cling to the measured ground, thus avoiding errors caused by loosening of the ground surface. Under the action of the measuring slide block, it brings convenience to observe whether the cone is vertical to the ground so as to further ensure errors of the thickness measured value.
Description
Technical field
The utility model relates to a kind of bituminous pavement paving thickness measurement chi, belongs to survey instrument design field.
Background technology
At present, in asphalt pavement construction engineering, the each Laminate construction thickness of surface layer is one of key factor of controlling Asphalt Pavement Construction Quality, and according to existing " Of Road Engineering Quality Checking And Evaluation standard ", the thickness of asphalt mat and compactness are two key projects of evaluation bituminous pavement quality.Unit in charge of construction adopts the drill rod of a taper to insert test surfaces mostly now, thereby the thickness of bituminous pavement top is measured.Adopt in this way in the time measuring, its error is larger, also has now a kind of testing tool, its structure mainly to comprise that axial location place arranges reeded cone, at groove inner face, scale is set, and cone top is provided with handle.This technology is measuring while using, owing to being the own assurance instrument of workman and the vertical situation of road surface pavement, so inaccurate situation on time while also there will be in the time measuring causes quality error in judgement.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: a kind of bituminous pavement paving thickness measurement chi is provided, and it is simple in structure, in the time measuring the thickness of asphalt mat, can effectively reduce the error of institute's Thickness Measurement by Microwave value.
A kind of bituminous pavement paving thickness measurement chi described in the utility model, comprise that axial location place arranges reeded cone, cone top is provided with handle, it is characterized in that: on the axis of cone, offer measurement chute, in measurement chute, level is put on measurement slide block, vertically be provided with spring in the measurement slide block left and right sides, spring upper end withstands on handle bottom, spring lower end withstands on measurement slider top, in the middle part of measuring slide block, be vertically fixed with sounding rod, corresponding sounding rod offers via hole on handle, sounding rod is through in via hole, on sounding rod, be provided with scale.
The preferred described spring of the utility model upper end is fixed on handle bottom.
For the scale on better protection bar, on the sounding rod between preferred described handle and measurement slide block, cover has the protective casing of telescopic structure.
Compared with prior art, the utlity model has following beneficial effect:
By a kind of bituminous pavement paving thickness measurement chi described in the utility model, it is simple in structure, in the time measuring the thickness of asphalt mat, can effectively reduce the error of institute's Thickness Measurement by Microwave value.Under the effect of spring, can make to measure slide block and be close to institute's geodetic face, can there is the loosening error of bringing of the floor surface avoided.Measuring under the effect of slide block, facilitate observation cone whether perpendicular to the ground, thereby further guaranteed the error of thickness measurements.
Brief description of the drawings
Fig. 1 is the utility model structural representation;
In figure: 1, sounding rod 2, handle 3, spring 4, measurement slide block 5, cone.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
Below by specific embodiment, the utility model is described in further detail; but not in order to limit the utility model; all within the present invention spirit and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
As shown in Figure 1, a kind of bituminous pavement paving thickness measurement chi, comprise that axial location place arranges reeded cone 5, cone 5 tops are provided with handle 2, on the axis of cone 5, offer measurement chute, in measurement chute, level is put on and is measured slide block 4, vertically be provided with spring 3 in measurement slide block 4 left and right sides, spring 3 upper ends withstand on handle 2 bottoms, spring 3 lower ends withstand on measures slide block 4 tops, vertically be fixed with sounding rod 1 at measurement slide block 4 middle parts, corresponding sounding rod 1 offers via hole on handle 2, sounding rod 1 is through in via hole, on sounding rod 1, be provided with scale.
In the present embodiment, described spring 3 upper ends are fixed on handle 2 bottoms; On sounding rod 1 between described handle 2 and measurement slide block 4, cover has the protective casing of telescopic structure.
Measure while use, hold handle 2 cone 5 is pressed in surveyed road surface, at this moment measure the elastic force that slide block 4 will overcome spring 3 and move upward, move sounding rod 1 and expose handle 2 outside surfaces from wearing, can carry out survey measurements work.Under the reacting force of spring 3, can push up to press and measure slide block 4 and be close on surveyed road surface, the measuring error that the reason such as prevented that road surface from becoming flexible is brought.
More than show and described ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and instructions, describes just illustrates principle of the present invention; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
