[0002] During the construction of highways, the quality of the roadbed plays a crucial role in the service life of the highway. An important factor reflecting the quality of the roadbed is the compaction degree of the roadbed, and a sand filling cylinder is required when measuring the compaction degree of the roadbed.

[0003] Common split-type sand cylinders for compaction degree detection only include the function of compaction degree detection, can detect the compaction degree of the roadbed, but lack the function of adjusting the capacity of the sand cylinder, and cannot ensure that enough sand and gravel can be contained in the sand cylinder for measurement. It is easy to occur that the sand cylinder cannot hold the sand volume adapted to the requirements in different detection requirements, affecting the detection accuracy.

[0004] Therefore, aiming at the problem that the common split-type sand cylinder for compaction degree detection lacks the function of adjusting the capacity of the sand cylinder, a split-type sand cylinder for compaction degree detection can be designed. By setting the combination of a telescopic plate and an L-shaped fixing plate, the upper sand filling cylinder can extend upward. Lift the upper sand filling cylinder to a specified height. During the upward movement of the upper sand filling cylinder, the telescopic plate will be pulled out from the inside of the telescopic groove, and then the bolt is passed through the adjustment hole and screwed into the inside of the fixing hole, so that the positions of the telescopic plate and the L-shaped fixing plate are fixed, thus ensuring that enough sand and gravel can be contained in the sand cylinder for measurement.

When it is necessary to expand the capacity of the lower sand filling cylinder 1, insert the upper sand filling cylinder 3 into the placement groove 2 from above the lower sand filling cylinder 1. At the same time, the four L-shaped fixing plates 6 are snapped into the connecting grooves 11. After the four L-shaped fixing plates 6 are snapped into the connecting grooves 11, rotate the upper sand filling cylinder 3 so that the bottom ends of the four L-shaped fixing plates 6 are snapped into the snap grooves 12, thus completing the fixation of the lower sand filling cylinder 1 and the upper sand filling cylinder 3. After the lower sand filling cylinder 1 and the upper sand filling cylinder 3 are fixed, lift the upper sand filling cylinder 3 upward. After the upper sand filling cylinder 3 moves upward to a specified height, pass the bolts through the adjusting holes 8 and then screw them into the fixing holes 5, so that the positions of the telescopic plate 4 and the L-shaped fixing plate 6 are fixed, thereby increasing the overall sand loading capacity and realizing the function of adjusting the capacity of the sand cylinder, preventing the problem that the sand cylinder cannot hold the sand volume adapted to the requirements in different detection requirements and affecting the detection accuracy.

[0027] When working, place the fixed collar 9 on the ground, then place the lower sand filling cylinder 1 inside the fixed collar 9, and pour an appropriate amount of gravel into the lower sand filling cylinder 1. When measuring, push the switch rod 15 to drive the sealing plate 16 to move left and right, so that the sealing plate 16 moves away from the sand outlet at the bottom of the lower sand funnel 13. At this time, the gravel flows downward from the sand outlet. When the gravel stops flowing downward, push the switch rod 15 to drive the sealing plate 16 to move to the sand outlet at the bottom of the lower sand funnel 13, so as to seal the sand outlet at the bottom of the lower sand funnel 13 through the sealing plate 16. Then measure the volume change of the soil before and after injecting the sand, and calculate the compaction degree of the soil according to the formula. When it is necessary to expand the capacity of the lower sand filling cylinder 1, insert the upper sand filling cylinder 3 from above the lower sand filling cylinder 1 into the placement groove 2. At the same time, the four L-shaped fixing plates 6 are clamped into the connecting groove 11. After the four L-shaped fixing plates 6 are clamped into the connecting groove 11, rotate the upper sand filling cylinder 3 so that the bottom ends of the four L-shaped fixing plates 6 are clamped into the buckle grooves 12, thus completing the fixation of the lower sand filling cylinder 1 and the upper sand filling cylinder 3. After the lower sand filling cylinder 1 and the upper sand filling cylinder 3 are fixed, lift the upper sand filling cylinder 3 upward. When the upper sand filling cylinder 3 moves upward to the specified height, pass the bolt through the adjustment hole 8 and screw it into the fixing hole 5, so that the positions of the telescopic plate 4 and the L-shaped fixing plate 6 are fixed, thereby increasing the overall sand loading capacity and realizing the function of adjusting the capacity of the sand cylinder.

[0028] Through the above steps, by setting the combination of the telescopic plate 4 and the L-shaped fixing plate 6, the upper sand filling cylinder 3 can extend upward. Lift the upper sand filling cylinder 3 upward to the specified height. During the upward movement of the upper sand filling cylinder 3, the telescopic plate 4 will be pulled out from the inside of the telescopic groove 7, and then pass the bolt through the adjustment hole 8 and screw it into the fixing hole 5, so that the positions of the telescopic plate 4 and the L-shaped fixing plate 6 are fixed, thus ensuring that enough gravel for measurement can be contained in the sand cylinder. To solve the problem of the common split-type sand cylinder for compaction degree detection, which only includes the function of compaction degree detection, can detect the compaction degree of the roadbed, but lacks the function of adjusting the capacity of the sand cylinder, and cannot ensure that enough gravel for measurement can be contained in the sand cylinder, and it is easy to occur that the sand cylinder cannot hold the sand volume adapted to the requirements in different detection requirements, affecting the detection accuracy.
