Description

Technical Field

[0001] The utility model relates to the technical field of roadbed backfill virtual paving thickness measurement, in particular to a roadbed backfill virtual paving thickness control and measurement tool. Background Art

[0002] The false paving thickness is also commonly known as the loose paving thickness, which is the paving thickness of the fill material before compaction. The ratio of the thickness before compaction to the thickness after compaction is the loose paving coefficient. Different false paving thickness values ​​are selected according to different compaction tools. The advantage of using impact compaction technology for roadbed compaction is that the loose paving thickness of the soil base is larger at one time. However, what is the range of the loose paving thickness of the soil base in order to achieve the best compaction effect? ​​This is a problem that integrates technology and economy. Reasonable determination of the loose paving thickness of the soil base at one time is also of great significance to the social benefits of highway construction and development. A special thickness measuring tool is required to measure the false paving thickness.

[0003] The Chinese patent with the announcement number CN217150288U discloses a device for controlling the backfill thickness of earth and stone, which includes a virtual thickness indicator frame, which includes a vertical rod with a backfill virtual thickness indicator scale and a horizontal rod for indicating the virtual thickness of the backfill, the horizontal rod can slide up and down along the vertical rod through a sliding member and can be fixed by a locking member, the bottom end of the virtual thickness indicator frame has a base for facilitating its placement on the ground, and multiple virtual thickness indicator frames are arranged at intervals along the periphery of the backfill area. The device has a simple and compact structure, is easy to operate, is convenient for day and night construction, and can achieve accurate control of the virtual thickness of earth and stone.

[0004] With respect to the above-mentioned related technologies, in the prior art, the staff places the base on the roadbed surface, uses the horizontal bar to contact the top of the measured false paving, and reads the reading on the vertical bar to measure the thickness of the false paving. However, the control device in the prior art needs to be placed on the roadbed surface in advance, and the filler of the false paving will immerse the bottom of the control device, so that dirt will adhere to the surface of the vertical bar. If the control device of the prior art is placed on the roadbed surface after the false paving, since it is impossible to observe the inside of the false paving, there is a possibility that there is a false paving filler between the base and the roadbed surface. The above two situations will affect the reading of the vertical bar, reducing the accuracy of the false paving thickness detection. Utility Model Content

The top end of the support column 1 is connected with a limiting plate 12 by bolts, and the areas of the support plate 11 and the limiting plate 12 are both larger than the cross-sectional area of ​​the support column 1. The surface of the support column 1 is provided with scale lines along its length direction.

[0032] Reference Figure 1 and Figure 2 The support column 1 is slidably matched with a slider 13, which is provided with a horizontal groove, through which the horizontal rod 2 passes and slidably matches. The slider 13 is provided with a locking member 131, which is a locking bolt, which passes through the slider 13 and abuts against the side wall of the horizontal rod 2, and the locking member 131 is threadedly matched with the slider 13.

[0033] Reference Figure 1 One end of the horizontal rod 2 is provided with an adjustment hole, and the measuring rod 3 passes through the adjustment hole and slides with the adjustment hole. The bottom end of the measuring rod 3 is arranged in a pointed cone shape, and the bottom end of the pointed cone-shaped measuring rod 3 is more convenient to insert into the virtual shop.

[0034] Reference Figure 1 and Figure 3 , a mounting assembly 4 is provided on the horizontal rod 2, and the mounting assembly 4 includes a pull rod 41, a clamping arc plate 42 and a torsion spring 43. A clamping groove 21 is provided on the inner wall of the adjustment hole, a rotating shaft is hinged on the side wall of the clamping groove 21, the clamping arc plate 42 is hinged in the clamping groove 21 through the rotating shaft, a rubber block 421 is fixedly connected to the arc wall of the clamping arc plate 42 close to the measuring rod 3, the rubber block 421 is against the surface of the measuring rod 3, and the rubber block 421 is used to increase the friction between the clamping arc plate 42 and the measuring rod 3.

[0035] Reference Figure 3 One end of the pull rod 41 is fixedly connected to the tight arc plate 42, and an escape groove is opened at the position of the horizontal rod 2 corresponding to the pull rod 41. The other end of the pull rod 41 passes through the escape groove and extends to the outside of the horizontal rod 2. The torsion spring 43 is sleeved on the rotating shaft, one end of the torsion spring 43 abuts against the side wall of the tight arc plate 42 away from the rubber block 421, and the other end abuts against the side wall of the tight groove 21. The torsion spring 43 is in a compressed state.

[0036] When installing the measuring rod 3, the staff pulls the pull rod 41 to drive the arc plate 42 to rotate, and the torsion spring 43 is compressed. Then the measuring rod 3 is inserted into the adjustment hole, the pull rod 41 is loosened, and the arc plate 42 is rotated in the opposite direction by the force of the torsion spring 43, so that the rubber block 421 is pressed against the surface of the measuring rod 3, thereby limiting the freedom of the measuring rod 3 and achieving the effect of installing the measuring rod 3.

[0037] Reference Figure 1 A limiting member 22 is provided at the other end of the horizontal rod 2. The limiting member 22 is a limiting bolt. The limiting member 22 passes through the horizontal rod 2 and is threadedly engaged with the horizontal rod 2.

[0039] The implementation principle of a roadbed backfill virtual paving thickness control and measurement tool in an embodiment of the present application is as follows: when measuring the virtual paving thickness of the roadbed backfill, the staff places the support plate 11 on the virtual paving surface, and at the same time, the bottom end of the measuring rod 3 touches the virtual paving surface. At this time, the reading of the slider 13 is 0, and then force is applied to press the top end of the measuring rod 3 to make the measuring rod 3 descend, driving the horizontal rod 2 and the slider 13 to descend until the bottom end of the measuring rod 3 touches the bottom wall of the roadbed. At this time, the value of the slider 13 is the actual thickness of the virtual paving position being measured, achieving the measurement effect of the measuring tool.

[0040] The staff uses the cooperation of the measuring rod 3, the horizontal rod 2 and the slider 13 to measure the value of the virtual paving thickness. The support column 1 is located above the virtual paving throughout the entire process, which reduces the possibility of dirt adhering to the surface of the support column 1 and ensures the clarity of the surface reading of the support column 1. At the same time, compared with the existing technology, the measuring rod 3 is used instead of the support column 1 to contact the virtual paving filler, which ensures the accuracy of the reading and improves the accuracy of the measuring tool.
