[0026] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0027] Reference below Figure 1-3 A depth measuring ruler 100 according to an embodiment of the present invention is described.

[0028] like Figure 1-3 As shown, according to the depth detection ruler 100 of the embodiment of the utility model, it can be used to detect the depth of the test pit. The depth detection ruler 100 includes: a measuring piece 10 and an abutment piece 20. The measuring piece 10 is perpendicular to and cross-connected with the abutment piece 20. The measuring piece 10 is vertically arranged in the test pit. The measuring piece 10 is a retractable piece. The abutment piece 20 can slide along the height direction of the measuring piece 10 to adjust the height of the abutment piece 20 so that it can abut against the top surface of the test pit.

[0029] It should be noted that during the construction of the roadbed, the detection of compaction is an important part of quality control. If the compaction test value is unqualified, it will greatly affect the overall construction quality of the road surface, and will cause structural damage to the road surface in a short period of time, and network cracks and potholes will appear on the road surface. When testing the compaction, the method of digging a pit and filling it with sand is usually used to test the compaction. The depth of the test pit is generally the thickness after compaction. Accurately measuring the compaction thickness can verify whether the loose paving coefficient of the roadbed is appropriate. Therefore, it is necessary to measure the depth of the test pit first.

[0030] Specifically, the measuring piece 10 of the depth detection ruler 100 of the present application is vertically arranged, and the abutment 20 is horizontally arranged. The abutment 20 and the measuring piece 10 are cross-connected, and the two always remain vertical. The measuring piece 10 is a retractable piece, which can be elongated to increase the height, or shortened to reduce the height, so as to match the test pits of different heights. The measuring piece 10 is placed vertically in the test pit, and the initial height of the connection between the abutment 20 and the measuring piece 10 is greater than the test pit height, so that the depth detection ruler 100 can be smoothly placed in the test pit. After the measuring piece 10 is placed, the abutment 20 can slide along the measuring piece 10 until its end is pressed against the top surface of the test pit. At this time, the abutment 20 is at the measuring height, and the scale on the measuring piece 10 corresponding to the abutment 20 is the depth of the test pit.

[0031] According to the depth detection ruler 100 of the embodiment of the utility model, by slidingly connecting the abutment member 20 and the measuring member 10, the height of the abutment member 20 can be conveniently and quickly adjusted so that it can be pressed against the top surface of the test pit, thereby being able to accurately and quickly measure the depth of the test pit to determine whether the construction requirements are met, thereby improving the detection accuracy; and the measuring member 10 is set as a telescopic member with adjustable height, so that the depth detection ruler 100 can be matched with test pits of different depths, thereby improving versatility.

[0032] like Figure 1-3 As shown, in some embodiments, the abutment member 20 has a connecting portion 21 and an abutment portion 22, and the corresponding two sides of the connecting portion 21 are respectively connected with the abutment portions 22, one end of the abutment portion 22 is connected to the connecting portion 21, and the other end of the abutment portion 22 extends toward the edge of the test pit, and the other end of the abutment portion 22 is pressed against the top surface of the test pit; the connecting portion 21 has a mounting hole 211, and the measuring piece 10 is inserted into the mounting hole 211; the connecting portion 21 includes an opening portion 212, and the opening portion 212 corresponds to the scale line of the measuring piece 10.

[0033] Specifically, the connecting portion 21 is connected to the measuring piece 10, and the connecting portion 21 has a mounting hole 211 that penetrates along the height direction. The connecting portion 21 is externally mounted on the measuring piece 10, and the measuring piece 10 fits in the mounting hole 211. An opening portion 212 is provided on the side of the connecting portion 21, and the opening portion 212 is opposite to the scale line on the measuring piece 10, so that the side of the connecting portion 21 can be opened to expose the scale line on the measuring piece 10, so as to facilitate observation of the appropriateness of the measurement.

[0034] It should be noted that a fixing hole is also provided on the side of the connecting portion 21, and the side with the fixing hole corresponds to the side with the opening 212. For example, the opening 212 and the fixing hole are provided on the side of the connecting portion 21 in the front-back direction, and the side of the connecting portion 21 in the left-right direction is connected with the abutment 22. The abutment 20 is arranged horizontally, and its size is larger than the inner diameter of the test pit. The ends of the two abutment 22 away from the connecting portion 21 are pressed against the top surface of the test pit, and the scale line of the measuring piece 10 corresponding to the bottom surface of the abutment 22 is the depth of the test pit. With this arrangement, the structure of the abutment 20 is simple, and the principle of measuring the depth of the test pit with the measuring piece 10 is simple. The depth of the test pit can be measured by adjusting the position of the abutment 20 so that it is pressed below the top surface of the test pit, which reduces the measurement difficulty and improves the measurement accuracy.

[0035] like Figure 1-3 As shown, in some embodiments, the abutment portion 22 is arranged at an angle, and the height of the top surface of the abutment portion 22 gradually decreases from the end close to the connection portion 21 toward the end away from the connection portion 21, and the bottom surface of the abutment portion 22 is flush with the bottom surface of the connection portion 21, and the end surface of the abutment portion 22 close to the connection portion 21 is larger than the end surface of the abutment portion 22 away from the connection portion 21. In this way, the abutment portion 22 is arranged at an angle, and the connection strength between the abutment portion 22 and the connection portion 21 can be ensured under the premise of reducing the weight of the depth detection ruler 100, and the bottom surface of the abutment portion 22 is arranged flush with the bottom surface of the connection portion 21, so that the scale line corresponding to the bottom surface of the abutment portion 22 is the depth of the test pit, which can reduce the measurement error and improve the accuracy of the measurement.

[0036] like Figure 1-3 As shown, in some embodiments, the measuring member 10 has a base 11 and a rod 12, the rod 12 is fixed to the top of the base 11, and the cross-sectional area of ​​the base 11 is larger than the cross-sectional area of ​​the rod 12. The height of the base 11 is determined, and for example, the height of the base 11 can be 0.5 cm, 0.8 cm, 1 cm, etc. The height of the base 11 can be set according to actual needs. The rod 12 is vertically fixed on the base 11, and the height of the test pit is the height of the scale line on the measuring member 10 corresponding to the abutment portion 22 plus the base 11. In this way, the rod 12 is set on the base 11, and the cross-sectional area of ​​the base 11 is larger than the cross-sectional area of ​​the rod 12, which is conducive to improving the stability of the measuring member 10, thereby improving the detection accuracy of the depth detection ruler 100.

[0037] Specifically, the rod body 12 is hollow and includes at least a first section and a second section. The lower end of the first section is connected to the base 11, and the second section is retractably arranged in the first section. When the test pit is deep and the scale line on the first section cannot meet the measurement requirements, the second section can be pulled out from the inside of the first section so that the depth detection ruler 100 can detect the deep test pit; when the test pit is shallow and the scale line on the first section can measure the test pit depth, the second section can be retracted into the inside of the first section to facilitate measurement. In this way, the rod body 12 is arranged to be retractable in multiple sections, which can increase the measurement range and thereby improve the versatility of the depth detection ruler 100.

[0038] like Figure 1-3 As shown, specifically, the rod body 12 has a corresponding first surface 121 and a second surface 122, the scale line of the measuring member 10 is set on the first surface 121, and the second surface 122 is provided with a limiting groove 1221, and the limiting groove 1221 extends along the height direction of the rod body 12. The depth detection ruler 100 also includes a locking member 30, and the locking member 30 is sequentially passed through the abutment member 20 and the measuring member 10 to fix the abutment member 20 to the measuring member 10.

[0039] It should be noted that the first surface 121 of the rod body 12 is opposite to the opening 212 of the connecting portion 21, and the second surface 122 of the rod body 12 is opposite to the fixing hole of the connecting portion 21. The second surface 122 is provided with a limiting groove 1221 that is recessed toward the first surface 121, and the fixing hole corresponds to the limiting groove 1221. The locking member 30 passes through the fixing hole of the connecting portion 21 and extends into the limiting groove 1221. The locking member 30 can be tightened to fix the abutment member 20 and the measuring member 10, or the locking member 30 can be loosened so that the abutment member 20 can slide along the measuring member 10. After the abutment member 20 is pressed against the top surface of the test pit, the locking member 30 is tightened to fix the abutment member 20 and the measuring member 10 to accurately read the value. For example, the locking member 30 can be a loose nut, and of course, it can also be other fasteners. This arrangement is convenient for tightening or loosening the connection between the abutment member 20 and the measuring member 10, and the operation is more convenient, which can ensure the accuracy of the data.
