Description

Technical Field

[0001] The utility model relates to the technical field of settlement observation, and particularly relates to a settlement observation device for high-fill subgrade. Background Art

[0002] High-fill subgrade is a common subgrade structure in highway engineering, especially widely used in mountainous and hilly areas and plain areas. Due to its large filling height and complex filler properties, high-fill subgrade is prone to uneven settlement, which affects the overall stability and safety of the road. Through settlement monitoring, potential settlement risks can be detected in time to avoid serious road safety accidents.

[0003] Traditional settlement observation devices usually obtain data through remote monitoring. It may be impossible for operators to directly obtain settlement information from the observation device in a timely and effective manner. During the construction process, if abnormal settlement of the subgrade is found, corresponding adjustments usually need to be made according to the settlement observation data. If information cannot be directly obtained, the construction adjustment will lack a scientific basis, which may lead to a further decline in construction quality, and potential settlement risks may not be detected in time, thus increasing the risk of road engineering safety accidents.

[0004] Therefore, it is necessary to invent a settlement observation device for high-fill subgrade to solve the above problems. Content of the Utility Model

A guide plate 14 is arranged inside the observation housing 1. A pulley block 12 is arranged at the top end of the guide plate 14. A counterweight lead block 13 is arranged on one side of the guide plate 14. The counterweight lead block 13 is detachably connected to a steel wire rope 4 that rotates around the pulley block 12. An indicator block 11 for displaying the settlement position is hoisted at the bottom end of the steel wire rope 4 on the other side of the guide plate 14. The bottom end of the indicator block 11 is connected to the steel wire rope 4. A protection pipeline 2 for laying the steel wire rope 4 and extending to the monitoring position is arranged below the observation housing 1. A plurality of monitoring components 3 for monitoring settlement data in different directions are arranged at the bottom end of the protection pipeline 2. The counterweight lead block 13 is arranged to lift the indicator block 11 to a certain height to prevent it from falling under the action of gravity and ensure its sliding effect through the pulling of the traction slider 17. The arrangement of the guide plate 14 can keep the indicator block 11 sliding in the guide groove 5 to ensure the observation effect.

[0023] A plurality of guide grooves 5 for the indicator block 11 to slide are formed on the outer side of the observation housing 1. Scale stripes 6 for displaying settlement data are formed on the outer side wall of the observation housing 1 where the guide grooves 5 are located. The arrangements of the guide grooves 5 and the scale stripes 6 ensure that the indicator block 11 can intuitively display the settlement value. The observation housing 1 also has various electronic components required for remote monitoring inside to meet different usage requirements.

[0024] The observation housing 1 is provided with a light-transmitting plate 7 for waterproofing and dustproofing on one side of the guide groove 5.

The light-transmitting plate 7 is provided to prevent an object from touching the sensor monitoring end 8, resulting in false alarms.

[0025] The end of the sensor monitoring end 8 is connected to an induction sensor 9. The induction sensor 9 is located on the side wall of the observation housing 1. The induction sensor 9 is electrically connected to an alarm device 10. The alarm device 10 is convenient for warning the surrounding workers to ensure that the problems brought by settlement are dealt with in time. The sensor monitoring end 8 can be provided with multiple ones in the vertical direction to meet the long-term monitoring of the roadbed.

[0026] The steel wire rope 4 located below the indicating block 11 extends to a designated monitoring area through the protective pipe 2.

The monitoring component 3 should be buried at the bottom of the roadbed during use to avoid the deviation of the monitoring component 3. The receiving plate 18 and the connecting shaft 19 are buried inside the roadbed to monitor the roadbed in real time. Positioning devices and other sensors can be arranged inside the receiving plate 18 to improve the accuracy of the observation results.

[0028] The auxiliary slider 16 penetrates to the outside of the induction part receiving block 15 and is connected to the traction slider 17. A sliding groove 20 is formed inside the monitoring component 3. The traction slider 17 slides longitudinally along the sliding groove 20. An auxiliary pulley can be arranged at the corner of the steel wire rope 4 to reduce the wear of the steel wire rope 4, so as to display the value more accurately.

[0029] In the present utility model, through the arrangement of a plurality of counterweight lead blocks 13, a steel wire rope 4 and a monitoring assembly 3, when the settling roadbed squeezes the bearing plate, it drives the pressing auxiliary slider 16, so as to realize the pulling of the steel wire rope 4 by the traction slider 17. The steel wire rope 4 pulls the indicating block 11 to slide downward, so that the settlement value is visually displayed on the scale stripes 6, facilitating the workers to intuitively understand the change of the settlement value in each area. The arrangement of the protective pipe 2 is used to prevent the steel wire rope 4 from being bent by the settling roadbed, affecting the observation accuracy.
