Description

Technical Field

[0001] The utility model belongs to the field of road construction, in particular to a tool for quickly measuring the virtual thickness elevation of road paving. Background Art

[0002] During the municipal road paving stage, accurate confirmation of the virtual paving thickness affects the thickness and uniformity after compaction. Good flatness and uniformity of each layer after compaction during the construction process are beneficial to road drainage, and are more beneficial to the service life of the road, and improve the comfort of vehicle traffic. If the virtual paving thickness is not well controlled during construction, the thickness after road construction is uneven, and the virtual thickness elevation does not meet the requirements, the road construction will be judged as unqualified, affecting acceptance and commissioning.

[0003] On the roadbed formed by construction, the flatness does not fully meet the standard requirements of flatness and slope, and there will be different degrees of convexity and concavity. Therefore, it is necessary to measure the elevation of the current topography of this point according to the arranged pile number and point position, and then calculate the actual height difference after this paving according to the design elevation of the pile number and cross slope position of this point, and then calculate the height difference according to the virtual paving coefficient of the material, that is: actual required paving thickness * virtual paving coefficient of paving material = virtual paving height. Because the point data changes randomly, especially the surveyors with less measurement experience, in the process of measuring and arranging points before paving, they measure and calculate in real time according to the height difference of each point. After calculating the virtual paving elevation data for each measured point, they inform the line hanging personnel to mark the virtual paving thickness here on the line hanging pole to meet the elevation required for subsequent paving machinery construction. At present, this measurement and calculation method has low operating efficiency and high error rate of frequent calculations. Especially when encountering a roadbed with poor flatness such as a slag roadbed, it is necessary to calculate as the measurement progresses. There are many measuring points, tight time, and long duration, and calculation errors often occur. Summary of the invention

[0011] Figure 1 This is a schematic diagram of the structure of this embodiment.

[0012] In the figure, 1 is the sector ruler, 2 is the pin shaft, and 3 is the conversion scale value. DETAILED DESCRIPTION

[0013] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0014] This embodiment includes a plurality of fan-shaped rulers 1 hinged together at the bottom ends, and the specific hinge method is that an axis hole is provided at the bottom end of each fan-shaped ruler 1, and the plurality of fan-shaped rulers 1 are stacked up and down, and the axis holes are aligned, and then the pin 2 passes through the axis holes of the plurality of fan-shaped rulers 1 to hinge them together, and the pin 2 is perpendicular to the fan-shaped ruler 1, and the fan-shaped ruler 1 can rotate around the pin 2 at the bottom end. A conversion scale value 3 is provided on any straight side or two straight sides of each fan-shaped ruler 1, and the bottom end point of the straight side of the fan-shaped ruler 1 is a zero scale point. In this embodiment, except that the rightmost fan-shaped ruler 1 is provided with conversion scale values ​​3 on both straight sides, the remaining fan-shaped rulers 1 are only provided with conversion scale values ​​3 on the left straight sides. The displayed value of the conversion scale value 3 is the theoretical paving thickness, and the actual scale value of the conversion scale value 3 is the product of the theoretical paving thickness and the virtual paving coefficient of the paving material. The theoretical paving thickness is the thickness after compaction. An example is given to illustrate: for example, if an asphalt layer is required, the theoretical paving thickness of the asphalt layer is 18 cm, and the virtual paving coefficient of the paved asphalt is 1.3, then the conversion scale value 3 displayed on the sector ruler 1 is 18 cm, and the actual scale of this displayed 18 cm conversion scale value 3 should be 23.4 cm, which is the actual thickness of the asphalt layer that needs to be paved, that is, the actual height from the zero point at the bottom of the sector ruler 1 to the point of 18 cm of the conversion scale value 3 is 23.4 cm. The conversion scale values ​​3 on different straight edges correspond to different virtual paving coefficients. Since the virtual paving coefficient of the road paving materials used in daily life is between 1.1-1.6, the virtual paving coefficients corresponding to the conversion scale values ​​3 are preferably 1.1, 1.2, 1.3, 1.4, 1.5, and 1.6, respectively. The conversion scale value 3 displayed on the sector ruler 1 ranges from 5 to 30 cm, and this scale range basically meets the paving thickness value of each layer of the road. The sector ruler 1 is preferably a transparent plastic ruler.

[0015] When in use, before hanging the line, the worker uses a level and a tower ruler to measure the height of the current point, and then calculates the actual theoretical paving thickness of the current point based on the theoretical paving thickness, and then turns the sector ruler 1 of the corresponding paving material virtual paving coefficient to the vertical state on the left, and directly finds the corresponding conversion scale value 3 on the sector ruler 1 according to the actual theoretical paving thickness, hangs the line at this conversion scale value 3, and then paving is carried out according to the hanging line. The following example illustrates the method of use: For example, if an asphalt layer needs to be paved, the theoretical thickness of the asphalt layer is 18cm, and the virtual paving coefficient of asphalt is 1.3. If the current point of measurement is a convex point (high point), and the worker uses a level and a tower ruler to measure that the current point is 3cm higher, then the actual theoretical thickness of the current point is (18-3)cm, and the actual theoretical thickness is 15cm. At this time, you only need to turn the straight edge of the scale with a virtual paving coefficient of 1.3 to a vertical state, and then ground the bottom, find the conversion scale value 3 of 15cm on this sector ruler 1, hang a line at the conversion scale value 3 of 15cm, and then pave according to the hanging line. In this example, the actual height value corresponding to 15cm on the sector ruler 1 is 19.5cm, so the actual thickness of the asphalt layer that needs to be paved (virtual paving thickness) is 19.5cm when constructing at the current point. The thickness of the asphalt layer after compaction is 15cm, plus the height of 3cm higher, which just reaches the theoretical thickness of 18cm.

[0016] The tool of the present invention can be applied to the paving of various road layers, and can be used in various construction processes with false paving coefficients such as lime soil layers, water-stable layers, and asphalt layers.

[0017] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
