AI Technical Summary
In the prior art, when using sand filling cylinders to determine the compaction degree of the roadbed, the height of the sand storage cylinder port is slow, making it difficult to accurately ensure that the sand cylinder is loaded 15mm±5mm from the top of the cylinder, affecting working efficiency.
A roadbed compaction detection equipment is designed, including a sand filling cylinder and a sand filling cylinder top positioning assembly. The positioning assembly consists of a positioning ring, a lap clamp and an auxiliary positioning thin rod, which is laply connected to the sand filling through a lap clamp. In the upper port of the cylinder, the positioning ring is exactly 15mm away from the top of the sand filling cylinder to ensure the accuracy and efficiency of the sand filling process.
Through this equipment, the sand filling process becomes convenient and quick, and the sand filling can be stopped accurately. When the sand filling contacts the positioning ring and auxiliary positioning thin rod, it is ensured that each sand filling can reach a predetermined height, which improves work efficiency.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of road engineering inspection, and in particular relates to roadbed compaction detection equipment. Background Art
[0002] Sand drums are suitable for measuring the bulk density of sand, gravel, gravel, graded gravel, cement stabilized soil, lime stabilized soil, etc. on construction sites. After each layer of fill is rolled on the highway roadbed, it is necessary to confirm whether the compaction of the roadbed layer is qualified before the next layer is constructed. The sand filling method for measuring compaction is one of the most commonly used methods for on-site testing of compaction of roadbed and pavement. The sand filling method uses uniformly granular sand to replace the volume of the test hole, which requires the use of a sand filling drum.
[0003] However, the sand is loaded into the sand storage barrel at the height of the barrel mouth until it is 15mm±5mm away from the barrel top, and then measured with a ruler. This method of measurement is slow, and it is often impossible to accurately ensure that the sand is loaded at a distance of 15mm±5mm from the barrel top in one go during the sand loading process. The back-and-forth adjustment is very slow, affecting work efficiency.
[0004] In view of this, the present utility model is proposed. Utility Model Content
[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:
[0006] A roadbed compaction detection device includes a sand filling cylinder and a sand filling cylinder top positioning assembly, which is arranged in the upper port of the sand filling cylinder; the sand filling cylinder top positioning assembly includes a positioning ring, and two symmetrically distributed overlapping clamps are installed on the positioning ring, and the overlapping clamps are overlapped on the upper port of the sand filling cylinder.
[0007] As a preferred embodiment of the present invention, a plurality of auxiliary positioning thin rods distributed at equal angles are installed on the inner side of the positioning ring.
[0008] As a preferred embodiment of the present invention, the hooking depth of the lap clamp is 15 mm.
[0009] As a preferred embodiment of the present invention, the cross-sectional diameters of the positioning ring and the auxiliary positioning rod are both 1 mm.
[0010] As a preferred embodiment of the present invention, the overlapping clamp, the auxiliary positioning rod and the positioning ring are all made of PVC plastic parts.
[0011] As a preferred embodiment of the present invention, handles are installed on both side walls of the sand filling cylinder.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] According to the utility model, before filling sand into the sand filling cylinder, the positioning ring is overlapped in the upper port of the sand filling cylinder through the overlap clamps at both ends of the positioning ring. At this time, the position of the positioning ring is just 15 mm away from the top of the sand filling cylinder. In this way, when filling sand, the sand is filled until it is flush with the positioning ring and the auxiliary positioning thin rod, or when the sand contacts the positioning ring and the auxiliary positioning thin rod, the sand filling can be stopped, and then the positioning ring and the auxiliary positioning thin rod can be taken out from the upper end of the sand filling cylinder. The whole sand filling process is convenient and fast.
[0014] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.
[0022] like Figures 1 to 4As shown, a roadbed compaction detection device includes a sand filling cylinder 1; and a sand filling cylinder top positioning assembly, which is arranged in the upper port of the sand filling cylinder 1; the sand filling cylinder top positioning assembly includes a positioning ring 3, and two symmetrically distributed overlapping clamps 4 are installed on the positioning ring 3, and the overlapping clamps 4 are overlapped on the upper port of the sand filling cylinder 1. Before filling sand into the sand filling cylinder 1, the positioning ring 3 is overlapped in the upper port of the sand filling cylinder 1 through the overlapping clamps 4 at both ends. At this time, the position of the positioning ring 3 is just 15 mm away from the top of the sand filling cylinder 1. In this way, when filling sand, the sand can be stopped when it is flush with the positioning ring 3 and the auxiliary positioning rod 5, or when the sand contacts the positioning ring 3 and the auxiliary positioning rod 5, and then the positioning ring 3 and the auxiliary positioning rod 5 can be taken out from the upper end of the sand filling cylinder 1. The entire sand filling process is convenient and quick.
[0023] like Figures 1 to 4 As shown, further, a plurality of auxiliary positioning thin rods 5 distributed at equal angles are installed on the inner side of the positioning ring 3 to ensure that the sand filling position can be observed in all directions at the inner opening of the sand filling cylinder 1.
[0024] like Figures 1 to 4 As shown, further, the hooking depth of the lap clamp 4 is 15 mm, which is convenient for directly positioning the distance from the cylinder top after sand filling.
[0025] like Figures 1 to 4 As shown, further, the cross-sectional diameters of the positioning ring 3 and the auxiliary positioning rod 5 are both 1 mm, so as to avoid temporary accumulation of sand on the positioning ring 3 and the auxiliary positioning rod 5 .
[0026] like Figures 1 to 4 As shown, further, the lap clamp 4, the auxiliary positioning rod 5 and the positioning ring 3 are all PVC plastic parts, which are light in weight and low in cost. Handles 2 are installed on both side walls of the sand filling cylinder 1.
[0027] The implementation principle of a roadbed compaction detection device of this embodiment is as follows: before filling sand into the sand filling tube 1, the positioning ring 3 is overlapped in the upper end of the sand filling tube 1 through the overlapping clamps 4 at both ends. At this time, the position of the positioning ring 3 is exactly 15 mm away from the top of the sand filling tube 1. In this way, when filling sand, the sand is filled until it is flush with the positioning ring 3 and the auxiliary positioning rod 5, or when the sand contacts the positioning ring 3 and the auxiliary positioning rod 5, the sand filling can be stopped, and then the positioning ring 3 and the auxiliary positioning rod 5 can be taken out from the upper end of the sand filling tube 1. The entire sand filling process is convenient and quick.
