Description

Technical Field

[0001] This application belongs to the field of highway construction technology, and in particular relates to a highway settlement measurement device. Background Technology

[0002] Highway engineering refers to all work related to the planning, design, construction, maintenance, and repair of structures that cross waterways, valleys, and all transportation routes. Highway construction generally includes surface treatment of the existing pavement structure, construction of the subgrade structure on the treated existing pavement structure, and construction of the pavement structure on the subgrade structure. The subgrade refers to the strip-shaped structure built according to the route location and certain technical requirements; it is the foundation of railways and highways and should possess sufficient strength, stability, and durability. Due to the varying terrain of the original pavement structure during construction, after reinforcement treatment, the original pavement structure and subgrade structure will experience stress and deformation under various loads from the pavement structure and traffic loads. To ensure the normal use and safety of the highway, the subgrade structure and the original pavement structure must possess sufficient strength and stability, and deformation should be within permissible limits. If settlement and displacement of the highway foundation cannot be effectively measured and monitored during use, highway maintenance personnel will find it difficult to detect the settlement and displacement phenomenon in time, affecting the safety of highway use. In the existing technology, the measuring device needs to be a precise measuring device, which is difficult to operate, time-consuming and labor-intensive, and has problems such as difficulty in reading values ​​and insufficient measurement accuracy.

[0027] To make the purpose, technical solution, and advantages of this application clearer, the following will be described in conjunction with the appendix. Figures 1-5The technical solutions of this application are clearly and completely described. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the described embodiments of this application are within the scope of protection of this application.

[0028] This application discloses a highway settlement measuring device, including a measuring device 1 and a measuring positioning mechanism 2 that cooperates with the measuring device 1; in a specific embodiment, such as Figure 1 As shown, the pavement structure 33 of the highway structure 3 is generally a rigid structure with very small settlement. Highway settlement is mainly caused by the subgrade structure 32 and the original pavement structure 31 at its bottom being subjected to various loads or self-weight. The landform outside the original pavement structure 31 has been solidified and usually does not settle. The measuring and positioning mechanism 2 is set on the outside of the original pavement structure, and the measuring device 1 is set on the pavement structure 33 accordingly. By setting the same detection location and taking multiple measurements at certain intervals, the settlement of the highway subgrade can be measured.

[0029] like Figures 2-3In the illustrated embodiment, the measuring device 1 includes a horizontal adjustment mechanism 4, a lifting adjustment mechanism 5 slidably connected to the horizontal adjustment mechanism 4, and a distance measuring mechanism 8 pulsatorically connected to the lifting adjustment mechanism 5. The horizontal adjustment mechanism 4 includes a support base plate 41 and support end plates 42 disposed at both ends of the support base plate 41. Leveling feet 49 are respectively disposed at the four corners of the bottom surface of the support base plate 41. There may be a certain slope on the side of the road surface structure. By rotating the leveling feet 49, the measuring device 1 can be leveled, thereby improving the measurement accuracy. Two guide rods 45 are arranged parallel to each other on the top sides between the two sets of support end plates 42. A guide sleeve 46 and a support plate 47 connected to the guide sleeve are slidably connected to the guide rods 45. The support plate can be stably slidably connected to the guide rods through the guide sleeve. A threaded sleeve 48 is fixedly connected to the bottom of the support plate 47. A horizontal adjusting screw 43 is rotatably connected between the two sets of support end plates 42. The threaded sleeve 48 is fitted on the horizontal adjusting screw 43, and one end of the horizontal adjusting screw 43 is connected to a first adjusting handle 44. By shaking the first adjusting handle 44 to rotate forward or backward, the lifting adjustment mechanism 5 and the distance measuring mechanism 8 can be driven to reciprocate horizontally along the guide rods through the horizontal adjusting screw 43. The lifting adjustment mechanism 5 includes a support longitudinal plate 51 fixedly connected to the support plate 47. A V-shaped groove 513 is longitudinally formed on one side of the support longitudinal plate 51. A support lug 512 is provided at the top of the V-shaped groove on the support longitudinal plate. The lifting adjustment screw 52 is rotatably connected between the support lug 512 and the support plate 47. A second adjustment handle 53 is provided at the top of the lifting adjustment screw 52. Guide rails 54 and four guide sliders 55 are slidably connected to the guide rails 54 on both sides of the support longitudinal plate 51. The guide sliders 55 are fixedly connected to one side of the first connecting block 6. A threaded sleeve that is driven by the lifting adjustment screw 52 is provided on the side of the first connecting block 6 near the support longitudinal plate 51. By shaking the second adjustment handle 53 to rotate forward or backward, the lifting adjustment screw 52 can drive the first connecting block 6 and the distance measuring mechanism 8 connected thereto to lift and adjust along the guide rail 54. A scale 511 is provided on the outer side of the support plate 51 along its longitudinal direction. An indicator needle 61 is provided on the side of the first connecting block 6 corresponding to the scale 511. When the lifting adjustment mechanism 5 adjusts the distance measuring mechanism 8 to the spatial height position, the indicator needle 61 and the scale 511 can be aligned with the original measurement starting point. For example, the indicator needle 61 is aligned with the 10, 20 or 30 mark of the scale 511, which makes it convenient to locate the measurement starting point in the subsequent measurement process and keep the measurement benchmark consistent.

[0030] like Figure 1In the illustrated embodiment, the measuring and positioning mechanism 2 includes a measuring guide rod 21 and a positioning cross plate 22 disposed at the top of the measuring guide rod 21. The positioning cross plate 22 serves as a reference plate for measurement. In an optional embodiment, a connecting mechanism may also be provided at the lower end of the measuring guide rod 21. The connecting mechanism can achieve a fixed connection between the original road surface structure or the road surface structure, such as using a positioning screw, a locking screw, or other structures. The measuring device 1 is disposed opposite to the positioning cross plate 22. By measuring the distance between the measuring device 8 and the positioning cross plate 22 at intervals multiple times, the settlement value of the highway subgrade can be calculated.

[0031] like Figure 3 and Figures 4-5 In the illustrated embodiment, a connecting crossbar 7 is fixedly connected to the side of the first connecting block 6 away from the supporting longitudinal plate 51. The distance measuring mechanism 8 includes a second connecting block 81 fixedly connected to the connecting crossbar 7. An L-shaped mounting plate 82 is fixedly connected to one side of the second connecting block 81. A control mechanism 83 is provided on the L-shaped mounting plate 82. The control mechanism 83 has a built-in generator, which is a laser generator or an ultrasonic generator. The top of the L-shaped mounting plate 82 is respectively provided with a transmitting end 84 and a receiving end 85 connected to the generator. The transmitting end 84 can emit light signals or sound signals, and the receiving end 85 can receive light signals or sound signals reflected by the positioning crossbar 22, thereby realizing the measurement of the distance between the distance measuring mechanism 8 and the positioning crossbar 22. This distance measuring mechanism 8 has the advantages of fast measurement speed and high accuracy.

[0032] A position indicator light 86 is installed on the second connecting block 81. The position indicator light 86 is electrically connected to the control mechanism 83 via a connecting cable. A cable clip 87 for fixing the connecting cable is installed on the back side of the L-shaped mounting plate 82. When the sound wave or light emitted by the generator hits the positioning plate 22, the position indicator light 86 lights up. The brightness or flashing of the position indicator light 86 can be set to indicate whether the measurement is complete. A display screen 88 is installed on the control mechanism 83. The display screen 88 can display the measured distance data. The difference between multiple measurements is the settlement value of the roadbed.

[0033] The above are preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
