Description

Technical Field

[0001] The utility model relates to the field of geotechnical engineering monitoring, and more specifically, to a support rod fixed ground surface monitoring settlement sensitive device. Background Art

[0002] Surface subsidence monitoring refers to the real-time monitoring, recording and analysis of surface subsidence through various monitoring means and technologies, so as to timely discover and solve subsidence problems.

[0003] In the process of engineering construction, surface subsidence monitoring is an indispensable part. Its main function is to timely grasp the impact of underground engineering construction on the surface, and to discover and warn potential safety hazards. Through real-time monitoring and analysis, the trend and change law of surface subsidence can be grasped, and corresponding measures can be taken in time to ensure the safety and stability of the project. In addition, through surface subsidence monitoring, it is also possible to timely discover and evaluate possible subsidence problems in the project, and take corresponding measures to adjust and repair them to ensure that the quality of the project meets the design requirements.

[0004] The existing technology is to bury poles at the surface monitoring points for monitoring, which is also the most widely used monitoring method. However, in actual construction monitoring, the bottom of the pavement structure will be hollowed out, mud will overflow, and other diseases will deeply affect the stability of the monitoring data. In severe cases, it may even cause the monitoring point to settle too much, the soil around the monitoring point to be hollowed out, and the monitoring will be insensitive. These problems will have an impact on engineering construction that cannot be ignored. Utility Model Content

[0010] Furthermore, the stabilizing component is connected to a settlement monitoring pole to limit horizontal movement of the settlement monitoring pole.

[0011] Furthermore, a ball bearing is arranged inside the support ring to reduce the friction between the support ring and the settlement monitoring pole.

[0012] Furthermore, the area around the connection between the upper part of the settlement monitoring pole and the support ring is polished to further reduce the friction between the support ring and the settlement monitoring pole.

[0013] Furthermore, the casing is provided with three layers of waterproof materials inside, in the middle and outside.

[0014] Furthermore, the depth of the casing exceeds the bottom elevation of the subbase or cushion layer of the soil layer by 8-10m.

[0015] Furthermore, the height difference between the upper surface of the settlement monitoring pole and the ground surface at least satisfies the depth of the minimum diameter tire embedded in the protective shell.

[0016] Furthermore, the bottom of the settlement monitoring pole is inserted into the original soil of the soil layer by 25-30 cm.

[0017] In general, the above technical solutions conceived by the utility model can achieve the following beneficial effects compared with the prior art:

[0018] 1. The utility model is a support rod fixed surface monitoring settlement sensitive device.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. In addition, the technical features involved in each embodiment of the utility model described below can be combined with each other as long as they do not conflict with each other.

[0025] Please refer to Figure 1 The utility model relates to a support rod fixed surface monitoring settlement sensitive device, comprising a settlement monitoring pole 10 with the bottom inserted into a soil layer 60, a fine sand layer 50 arranged in the middle of the settlement monitoring pole 10, a stabilizing component 20 fixedly arranged at the upper end of the settlement monitoring pole 10, a protective shell 30 connected to the stabilizing component 20, and a casing 40 arranged outside the protective shell 30 and isolating the fine sand layer 50 and the soil layer 60;

[0026] The settlement monitoring rod 10 passes through the stabilizing assembly 20, the fine sand layer 50 and the soil layer 60 from top to bottom. The device reflects the settlement of the soil layer 60 through the vertical movement of the settlement monitoring rod 10 and the fine sand content of the fine sand layer 50.

[0027] The height difference between the upper surface of the settlement monitoring pole 10 and the ground surface is at least enough to meet the depth of the minimum diameter tire embedded in the protective shell. And the bottom of the settlement monitoring pole 10 is inserted into the original soil of the soil layer 60 by 25-30 cm.

[0028] The stabilizing component 20 is connected to the settlement monitoring pole 10 to limit the horizontal movement of the settlement monitoring pole 10 .

[0029] The casing 40 is provided with three layers of waterproof materials inside, middle and outside to reduce damage to the road. The depth of the casing 40 exceeds the bottom elevation of the subbase or cushion layer of the soil layer 60 by 8-10m.

[0030] Please refer to Figure 2The stabilizing assembly 20 includes a plurality of connecting rods 21, a support ring 22 and a hinge structure 23. One end of the connecting rod 21 is fixedly connected to the support ring 22, and the other end of the connecting rod 21 is connected to the protective shell 30 through the hinge structure 23. The connecting rod 21 rotates around the hinge structure 23. When the ground settles, the connecting rod 21 can perform corresponding rotational movement through the flexibility of the hinge structure 23 (the hinge shaft 231 can move left and right in the hinge sleeve 232), thereby improving the adaptability and stability of the device. In order to ensure the normal use of the device, the angle between the connecting rod 21 and the protective shell 30 cannot exceed 90 degrees, that is, the settlement monitoring benchmark 10 cannot move upward.

[0031] A ball bearing is arranged inside the support ring 22 to reduce the friction between the support ring 22 and the settlement monitoring pole 10. When settlement is achieved, the settlement monitoring pole 10 can move vertically sensitively.

[0032] The area around the connection between the upper part of the settlement monitoring pole 10 and the support ring 22 is polished to further reduce the friction between the support ring 22 and the settlement monitoring pole 10.

[0033] In some preferred embodiments, a data acquisition system may be introduced to realize functions such as real-time monitoring and automated detection, for example, by using real-time monitoring technology, remote data transmission technology, data processing algorithms, automated monitoring systems and data visualization technology.

[0034] Among them, real-time monitoring technology uses sensors and data acquisition equipment to monitor the position changes of settlement monitoring poles in real time. The sensors can continuously collect data and transmit it to the data acquisition system to achieve real-time monitoring of surface settlement.

[0035] Remote data transmission technology transmits the collected data to a remote server or monitoring center via the Internet or other wireless communication technologies. This enables remote monitoring and real-time data transmission, ensuring the timeliness and integrity of the data.

[0036] Data processing algorithms can be optimized to process and analyze the collected data in real time. Technologies such as data mining and machine learning can be applied to extract useful information and issue alarms or generate monitoring reports in a timely manner so that corresponding measures can be taken in a timely manner.

[0037] Automated monitoring system: By establishing an automated monitoring system, automatic calibration, fault diagnosis and data processing of monitoring devices can be achieved, reducing human intervention and improving monitoring efficiency and accuracy.

[0038] Data visualization technology, through the design of an intuitive data visualization interface, displays the monitoring data in the form of charts, curves, etc., making it convenient for users to intuitively understand the surface subsidence situation.

[0039] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
