Abstract
The utility model discloses a bituminous pavement paving depth measurement ruler, solving the problems that the conventional bituminous pavement paving depth is difficult to measure accurately, and the measurement error occurs frequently. The bituminous pavement paving depth measurement ruler provided by the utility model mainly comprises a conical body (1) and a graduation ruler arranged on the conical body (1). According to the bituminous pavement paving depth measurement ruler, the bituminous pavement paving depth can be measured accurately in real time, and the bituminous pavement paving depth measurement ruler has the advantages of being convenient to carry, safe and reliability in measurement result, and the like.
Description
Technical field
The utility model relates to a kind of survey instrument, specifically is meant a kind of survey instrument of measuring bituminous pavement paving thickness.
Background technology
In asphalt pavement construction; Each Laminate construction thickness of surface layer is the key of decision bituminous pavement quality; According to existing " highway engineering quality check evaluation criterion "; The thickness of asphalt mat and compactness are two key projects of evaluation bituminous pavement quality, and the thickness of bituminous pavement top is to obtain a coefficient of loose laying through the examination shop, will check paving layer thickness and road camber, horizontal wall inscription in the paving process at any time.
During practice of construction, the loose laying depth of confirming according to coefficient of loose laying is the major influence factors of thickness after the decision final compacting in road surface, and to the inspection of loose laying depth normally at the paving thickness of back inspection compound that paves.
Paving thickness does not still have special-purpose thickness measurement chi or analyzer at present, now is that unit in charge of construction passes through the drill rod of a taper is inserted test surfaces mostly, afterwards, draws according to the depth survey of inserting, and way has following shortcoming like this:
(1) paving thickness of being measured is reading in real time, need will test to measure with steel ruler after used taper-type dropper takes out, in case and after this taper-type dropper taking-up, the judgement of position may exist certain error perhaps to exist than mistake during to insertion again.
(2) because the used taper-type dropper of test does not have scale mark; Need carry steel ruler or tape measure equidimension testing tool; Otherwise can't accurately measure, and the scene need accurately be measured at any time so that paving thickness is carried out real-time monitoring, so just brings very big inconvenience to measurement.
(3) overall shape of used taper-type dropper is a conico-acuminate, vertically insert test surfaces after, there are certain inclination angle in the edge of taper-type dropper and test surfaces out of plumb, the appearance at this inclination angle is easy to cause test errors.
(4) the most advanced and sophisticated position of used taper-type dropper is often too thin, inserts the subjacent bed certain depth when dynamics is excessive easily, can bring error to test result like this, but when used dynamics is too small, possibly fail to reach the paving layer bottom again, thereby test error occur.
The utility model content
The purpose of the utility model is to solve existing bituminous pavement paving thickness and can't detects and measure inaccurate in real time, the problem of test error usually occurs.A kind of bituminous pavement paving thickness measurement chi that addresses the above problem is provided.
The utility model is realized through following technical proposals: bituminous pavement paving thickness measurement chi mainly is made up of cone and the rule that is arranged on the cone.
Further, the shape of said cone and the cone shape of cutting wherein half structure that the back forms open along axis is identical.
In order better to realize being provided with groove at the axial location place of said cone by the utility model, said rule then is arranged at the recess edge place.
As a kind of preferred, said recess width is 1mm.
For fear of measuring inaccurate problem, be set to planar structure at the tip of said cone.
As the embodiment of optimum, said cone length is 15cm.
Insert test surfaces during for the ease of test, the upper end of said cone is provided with handle.
The utility model compared with prior art has the following advantages and beneficial effect:
(1) cone of the utility model is provided with rule, can measure the paving thickness of bituminous pavement accurately;
(2) to cut the wherein half the structure that the back forms open along axis identical for the structure of the utility model cone and cone; The side vertical when so just existing one to insert test surfaces with test surfaces; Measuring error is avoided in the appearance at inclination angle in the time of can effectively avoiding inserting;
(3) the axial location place of the utility model is provided with groove, is provided with rule at the marginal position place of this groove, and being provided with of this groove and rule can make measurement more accurate;
(4) tip of the utility model cone is set to planar structure, has avoided the most advanced and sophisticated meticulous of cone like this, is prone to insert subjacent bed and brings test error;
(5) the utility model cone length is 15cm, satisfies the paving thickness of existing each structural sheet of bituminous pavement fully;
(6) the cone upper end of the utility model is provided with handle, inserts when being convenient to test;
(7) the utility model is easy to carry, test result safety, reliable.
Description of drawings
Fig. 1 is the one-piece construction synoptic diagram of the utility model.
Fig. 2 is the left view of Fig. 1.
The parts name that Reference numeral is corresponding among the figure is called:
1-cone, 2-groove, 3-planar structure, 4-handle.
Embodiment
Below in conjunction with embodiment the utility model is done to specify further, but the embodiment of the utility model is not limited thereto.
Embodiment
Like Fig. 1, shown in Figure 2, the utility model mainly is made up of cone 1 and the rule that is arranged on the cone 1.The shape of said cone 1 is identical with the shape that cone is cut back wherein half structure that forms open along axis.The place is provided with groove 2 in said axial location, and said rule then is arranged at groove 2 edges.The upper end of said cone 1 is provided with handle 4.Be set to planar structure 3 at the tip of said cone 1.
In the present embodiment, the width of groove 2 is set to 1mm, and the length of cone 1 is set to 15cm.Because of current specifications regulation bituminous pavement individual layer maximum ga(u)ge is 10cm, its paving thickness is no more than 15cm, so the length of cone 1 is set to the demand that 15cm can satisfy the user fully.
During test; Hold handle 4 cone 1 is inserted in the test surfaces, the wherein half the structure of cutting back formation open along axis because of the structure and the cone of cone 1 is identical, has just formed side vertical with test surfaces when one is inserted test surfaces; Thereby avoided the appearance at inclination angle, influenced accuracy of test.The back blacktop has certain construction depth because pave; And this construction depth bigger before rolling (in, coarse grain formula compound the fluctuation range about 5mm is arranged); The existence of this construction depth; Cause easily the thickness judge of inserting is caused than mistake, therefore be provided with groove 2 at the axial location place.Rule according to groove 2 marginal position places just can directly read the thickness that inserts, thus the measuring error of avoiding.In order to measure accurately, degree of accuracy is set to 1mm on the rule.Meticulous for fear of cone 1 most advanced and sophisticated position, insert the test errors that subjacent bed brings easily, so the tip of cone 1 is set to planar structure 3.
When test, for accurately paving thickness being measured, can read the scale mark at groove 2 edges of laminar object and test surfaces infall with smooth laminar objects such as steel ruler, cards along sliding to test surfaces under the groove, can accurately measure institute's Thickness Measurement by Microwave in real time; The scale place of perhaps being close to test surfaces and rule with a laminar object also can carry out in real time, accurately measure thus test thickness.
As stated, just can realize the utility model preferably.
