Abstract
Description
Technical Field
[0001] This utility model relates to the field of deep soil settlement monitoring technology, and in particular to a device for raising the measuring rod for deep soil settlement monitoring. Background Technology
[0002] When monitoring deep soil settlement, the settlement plate method has become a commonly used monitoring method due to its mature technical system, high observation accuracy and wide monitoring area. Its working principle is based on the displacement measurement principle in physics. When the foundation settles, the settlement plate will sink accordingly. Through measuring devices such as a leveling instrument and an invar steel ruler, this settlement change can be converted into quantifiable data, thereby realizing effective monitoring of soil settlement.
[0003] In practical engineering applications, when deep soil settlement monitoring points are located on operational roads, a series of unique challenges arise. To ensure normal passage for vehicles and pedestrians, the settlement monitoring pole head cannot protrude from the road surface as usual; instead, it must be positioned at a certain depth below the road surface. This makes it difficult to properly erect the indium steel ruler on the settlement monitoring pole during monitoring, failing to meet monitoring requirements and necessitating temporary heightening. After each monitoring session, the heightening device is removed, and normal road traffic is restored. The heightening device is then reinstalled for the next soil settlement monitoring session. Currently, the market lacks convenient, flexible, and simple settlement monitoring pole heightening devices specifically designed for these special conditions, making settlement monitoring work difficult in these scenarios and affecting the accuracy and completeness of monitoring data. Therefore, it is necessary to develop a convenient, flexible, and simple settlement monitoring pole heightening device suitable for operational roads to ensure the accuracy and completeness of soil settlement monitoring data without affecting normal road operation. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a device for raising the measuring rod for monitoring deep soil settlement. This device solves the problem that when monitoring deep soil settlement, a ruler needs to be erected at the head of the measuring rod. Because the measuring point is located on an operating road, the head of the measuring rod cannot protrude from the road surface as in conventional cases. Furthermore, when the deep soil settlement plate is buried, the drilling diameter of the drilling rig is small, making it impossible for the indium steel ruler to be inserted into the measuring rod.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A device for raising a soil deep settlement monitoring rod includes a roadbed surface, a deep hole is formed on the roadbed surface, a settlement plate is installed in the deep hole, a settlement measuring rod is fixedly installed on the top of the settlement plate, the settlement measuring rod is located below the roadbed surface, a heightening tube is installed on the settlement measuring rod, and a stable placement component is provided between the heightening tube and the settlement measuring rod.
[0006] Preferably, the reinforced tube is provided with an upper sleeve and a lower sleeve, and a solid partition is provided between the upper sleeve and the lower sleeve, with the solid partition in contact with the top of the settlement measuring rod.
[0007] Preferably, the upper sleeve has an arc-shaped top surface, and the lower sleeve has an arc-shaped bottom guide plate.
[0008] Preferably, the stable placement assembly includes a side extension ring disposed on the lower sleeve, the side extension ring having a placement slot, and an airbag disposed within the placement slot.
[0009] Preferably, one side of the airbag is connected to an inflation nozzle, one side of the inflation nozzle extends above the roadbed surface, and a sealing plug is provided at the end of the inflation nozzle.
[0010] Preferably, an isolation tube, which is a PVC pipe, is installed on the inner wall of the deep hole.
[0011] Compared with the prior art, the beneficial effects of this utility model are: the soil deep settlement monitoring rod heightening device is easy to operate, and the surveyors do not need complicated tools to quickly complete the installation of the heightening rod, so as to carry out the next settlement measurement work, which significantly reduces the time of traffic interference caused by settlement monitoring operations; The device is flexible and simple. The settlement measuring rod is temporarily heightened during each monitoring operation. The heightened length of the settlement measuring rod is the length of the upper sleeve. After each monitoring is completed, the heightened section is removed and the road is restored to normal operation and traffic. The device also features high stability, effectively avoiding problems such as measurement data deviation, providing reliable protection for settlement monitoring and ensuring the accuracy of monitoring data.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Example: Refer to Figure 1-4 A soil deep settlement monitoring rod heightening device includes a roadbed surface 1, a deep hole 2 opened on the roadbed surface 1, a settlement plate 3 installed in the deep hole 2, a settlement measuring rod 4 fixedly installed on the top of the settlement plate 3, the settlement measuring rod 4 being located below the roadbed surface 1, a heightening tube 6 installed on the settlement measuring rod 4, a stabilizing component being provided between the heightening tube 6 and the settlement measuring rod 4, and an isolation tube 5, which is a PVC pipe, installed on the inner wall of the deep hole 2.
[0016] Specifically, the heightening tube 6 is equipped with an upper sleeve 7 and a lower sleeve 9. A solid partition 8 is installed between the upper sleeve 7 and the lower sleeve 9. The solid partition 8 is in contact with the top of the settlement measuring rod 4. During the monitoring of deep soil settlement, the heightening tube 6 needs to be installed on the settlement measuring rod 4. The settlement measuring rod 4 is inserted into the lower sleeve 9 of the heightening tube 6. The bottom arc-shaped guide plate 11 is provided. The arc shape guides the heightening tube 6 to be inserted and placed on the settlement measuring rod 4 more conveniently. When the top of the settlement measuring rod 4 contacts and locks with the bottom of the solid partition 8 of the heightening tube 6, the heightening of the settlement measuring rod 4 is completed.
[0017] Specifically, the upper sleeve 7 has an arc-shaped top surface 10, and the lower sleeve 9 has a bottom arc-shaped guide plate 11. The stable placement assembly includes a side extension ring 12 on the lower sleeve 9, a placement slot 13 on the side extension ring 12, an airbag 14 inside the placement slot 13, an inflation nozzle 15 connected to one side of the airbag 14, one side of the inflation nozzle 15 extending above the roadbed surface 1, and a sealing plug 16 at the end of the inflation nozzle 15. The airbag 14 is inflated by an air pump, and after inflation, it expands and contacts the surface of the settlement measuring rod 4, achieving stable contact and compression. The reinforcement tube 6 and the settlement measuring rod 4 achieve a stable connection. In subsequent measurements, the reinforcement tube 6 is less likely to shake, has good stability, and avoids shaking from affecting the accuracy of the measurement.
[0018] Specifically, the elevation change of the top arc surface 10 of the heightening tube 6 is measured by a level instrument, thereby realizing soil settlement monitoring. The solid partition 8 hinders the stroke of the settlement measuring rod 4 when it is inserted, thus increasing the height of the settlement measuring rod 4. The increased length of the settlement measuring rod 4 is the length of the upper sleeve 7. The arc surface 10 is set to increase the stability of the elevation measurement data.
[0019] In use: During deep soil settlement monitoring, a heightening tube 6 needs to be installed on the settlement measuring rod 4. The settlement measuring rod 4 is then inserted into the lower sleeve 9 of the heightening tube 6. When the top of the settlement measuring rod 4 contacts and locks into place with the bottom of the solid partition 8 of the heightening tube 6, the heightening of the settlement measuring rod 4 is completed. Then, the elevation change of the top arc surface 10 of the heightening tube 6 is measured using a level instrument, thereby realizing soil settlement monitoring. The solid partition 8 obstructs the stroke of the settlement measuring rod 4 during insertion, thus achieving the heightening of the settlement measuring rod 4. The heightened length of the settlement measuring rod 4 is the length of the upper sleeve 7. The arc surface 10 is designed to increase the stability of the elevation measurement data and facilitates use.
