Description

[0001] The invention relates to the technical field of road engineering detection equipment, in particular to a settlement monitoring device for roadbed and pavement engineering construction. Background Art

[0002] The roadbed, as the cornerstone of road construction, directly bears the traffic load transmitted by the road surface and evenly distributes these loads to the foundation. It plays a vital load-bearing role in the road structure, and its stability is directly related to the efficiency and life of the road. During the construction of the excavation roadbed, as the project gradually advances, the base surface will naturally drop. Similarly, after the excavation or filling operation is completed, the roadbed base surface will also settle due to the rolling and compaction of the construction. In order to ensure the stability of the road after construction, the settlement height must be strictly controlled according to the project settings. Roadbed settlement refers to the vertical deformation of the roadbed under the action of load. In the existing construction, the settlement height is monitored by a single pole measurement or the use of settlement nails. As the project progresses, it is measured with a ruler.

[0025] Working principle: S1. First, before using the device, charge it through the charging port 15; S2. When in use, the base 21 in the main assembly 2 is placed on the ground, and then the user needs to apply force with the sole of the foot to the middle of the main frame 23 (located above the base 21) so that the insertion rod 24 on the lower wall of the base 21 can be smoothly inserted into the ground, thereby fixing the device; S3. The device is controlled by the button 14 to perform monitoring with the power supply of the battery box 11; that is, after the device is fixed, the first monitoring structure 4 in the parallel corresponding state is controlled by the button 14, and the third motor 41 is driven to drive one of the flip arms 42 to flip, so that the grounding seat 45 is lowered and attached to the ground. Since the flip arms 42 are symmetrically arranged in parallel, and the telescopic arm 44 at the other end of the flip arms 42 is movably connected to the grounding seat 45, the flip arms 42 are synchronously flipped in parallel, driving the grounding seat 45 to rise and fall. When the grounding seats 45 in the two first monitoring structures 4 are attached to the ground, the second motor 27 is controlled to drive the infrared ray detector 29 on the first shaft 28 to flip, so that the rays of the infrared ray detector 29 are irradiated on the reflective plate 46 and the irradiation angle of the infrared ray detector 29 is adjusted, so that the rays of the infrared ray detector 29 are refracted to form a significant first point on the other end of the grounding seat 45, and the device records the height position of the contact seat; S4. When the road surface of the roadbed settles, the grounding seat 45 in the first monitoring structure 4 is driven to descend to the height position of the first point again by the device, and then one of the grounding seats 45 equipped with the rack 51 is driven to flip and descend, and the corresponding electric slide rail 43 is driven to drive the telescopic arm 44 to telescopically move to fit the grounding seat 45, so that the grounding seats 45 in the two first monitoring structures 4 are correspondingly vertically descended and fit to the settled ground; S5. Then the infrared ray device 29 of the first monitoring structure 4 in the two imaging cameras 3 automatically determines the irradiation point height difference to achieve the measurement of the settlement height and display it on the first display screen 12; S6. When the grounding seats 45 in the two first monitoring structures 4 are relatively staggered, the rack 51 will mesh with the gear 54 in the second monitoring structure 5 as the grounding seat 45 descends, driving the gear 54 to rotate in the wheel seat 53, and then the rotation of the gear 54 drives the rotating rangefinder 55 to measure the descending height of the rack 51, that is, measure the position difference between the two points of the corresponding grounding seat 45 and display it on the second display screen 13, so as to achieve secondary measurement of the settlement height; S7. During use of the device, the first bolt 25 can be rotated to adjust the bracket 26 to move up and down on the main frame 23 to adjust the base height of the first monitoring structure 4; S8. After being fixed, the equipment can also synchronously adjust the height of the grounding seat 45 in the first monitoring structure 4, so that the grounding seat 45 is located above the ground before construction, and then drive one of the grounding seats 45 in the first monitoring structure 4 to be staggered relative to the other grounding seat 45 and descend to fit the ground, and then drive the rack 51 to descend to drive the second monitoring structure 5 to measure the descending height from the base position height to the base road surface height; After the roadbed settlement construction, a secondary drive measurement is carried out, and the difference in the measured values ​​on both sides is the settlement height of the original construction road surface after construction.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Other modifications or functional replacements made to the technical solution of the present invention by ordinary technicians in the field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
