Description

Technical Field

[0001] This utility model relates to the field of road monitoring technology, specifically to a column-type road surface prism measuring point auxiliary device. Background Technology

[0002] Currently, the main method for monitoring urban roads and highways is to deploy road studs, then manually support indium steel rulers, prism tripods, and other supports in conjunction with levels and total stations. However, for monitoring operational urban roads and highways, these current methods pose traffic safety hazards. Furthermore, for horizontal displacement monitoring, the manual support of prism tripods introduces errors in point alignment each time, significantly impacting the monitoring results and resulting in insufficient accuracy to meet user needs. Utility Model Content

[0003] To address the aforementioned technical issues, a column-type road prism measuring point auxiliary device is provided, which solves the technical problem of point alignment error in manually supported prism support devices, thereby improving the accuracy of road horizontal displacement monitoring and enhancing safety.

[0004] To achieve the above objectives, the following solution is provided: a column-type road prism measuring point auxiliary device, comprising a support column, a prism, a ground fixing module and an underground fixing module, wherein the underground fixing module is set inside the ground, the ground fixing module is installed on the road surface, the support column is vertically installed inside the ground fixing module and the underground fixing module, and the prism is installed at the top of the support column;

[0005] The underground fixing module includes an outer sleeve, cement mortar filler and a first sand filler. Installation holes are provided at the road surface and ground surface. The outer sleeve is inserted into the installation holes and the top of the outer sleeve is flush with the road surface. One end of the support column is inserted into the outer sleeve. The lower part of the outer sleeve is filled with cement mortar filler and the upper part of the outer sleeve is filled with the first sand filler.

[0006] The ground-mounted module includes a fixing pipe, a support base, and a second sand filler. The fixing pipe is fixedly installed on the support base, which is fixedly installed on the road surface. The fixing pipe and the support base are sleeved on the outside of the support column, and the second sand filler is filled between the support column and the fixing pipe.

[0007] Furthermore, the support column is a stainless steel rod.

[0016] The following detailed explanation illustrates the specific implementation methods:

[0017] like Figure 1 As shown:

[0018] A column-type pavement prism measuring point auxiliary device includes a support column 7, a prism 8, an above-ground fixing module, and an underground fixing module. The underground fixing module is set inside the ground 1, and the above-ground fixing module is installed on the pavement 2 on the ground 1. The support column 7 is vertically installed inside the above-ground fixing module and the underground fixing module. Through the coordinated action of the above-ground fixing module and the underground fixing module, the support column 7 can be installed on the pavement 2 and the ground 1. The pavement 2 consists of an asphalt pavement layer 2, a subgrade base layer, and a subgrade cushion layer from top to bottom. The prism 8 is installed at the top of the support column 7. The prism 8 is used in conjunction with a corresponding level or total station.

[0019] The underground fixed module includes an outer sleeve 3, cement mortar filler 4, and first sand filler 5. Installation holes are opened at the road surface 2 and the ground surface 1. The outer sleeve 3 is inserted into the installation hole and the top of the outer sleeve 3 is flush with the road surface 2. The outer sleeve 3 can support the side wall of the installation hole to prevent the installation hole from collapsing. The size of the installation hole is slightly larger than the outer diameter of the outer sleeve 3 to facilitate the insertion of the outer sleeve 3 into the installation hole. Then, soil is backfilled in the gap between the outer sleeve 3 and the installation hole. One end of the support column 7 is inserted into the outer sleeve 3, and a counterweight 6 is installed at the bottom of the support column 7. The lower part of the outer sleeve 3 is filled with cement mortar filler 4, which wraps the counterweight 6. The upper part of the outer sleeve 3 is filled with first sand filler 5 to fill the upper space of the outer sleeve 3.

[0020] The ground-mounted module includes a fixing pipe 9, a support base 10, and a second sand filler 11. The fixing pipe 9 is fixedly installed on the support base 10, and the support base 10 is fixedly installed on the road surface 2 to form an external support component. The fixing pipe 9 and the support base 10 are sleeved on the outside of the support column 7. The second sand filler 11 is filled between the support column 7 and the fixing pipe 9. The ground-mounted module can fix the upper part of the support column 7.

[0021] Support column 7 is made of stainless steel, which has the characteristics of high strength and corrosion resistance.

[0022] A counterweight 6 is installed at one end of the support column 7 that is inserted into the cement mortar filler 4.

[0023] Prism 8 is an L-shaped prism.

[0024] The outer casing 3 is a PVC pipe.

[0025] Fixed pipe 9 is a galvanized steel pipe.

[0026] The specific implementation process is as follows:

[0027] When using this device, a handheld drilling rig is used to drill the asphalt concrete layer, subgrade base layer, and subgrade cushion layer of the road surface 2. Then, a hole is punched in the ground 1 at the center of the drilled hole to form an installation hole. The outer sleeve 3 is inserted into the installation hole. Next, the end of the support column 7 with the counterweight 6 is vertically inserted into the outer sleeve 3. Then, cement mortar filler 4 is poured into the outer sleeve 3, so that the cement mortar filler 4 fills the lower part of the outer sleeve 3 and wraps the counterweight 6. After the cement mortar filler 4 has solidified for half an hour, the first sand filler 5 is filled into the outer sleeve 3. Then, a fixing pipe 9 and a support base 10 are fitted on the outside of the support column 7. The base of the support base 10 is anchored to the road surface 2 layer with expansion bolts. The second sand filler 11 is filled into the fixing pipe 9 to fill the gap between the support column 7 and the fixing pipe 9. Finally, a prism 8 is installed on the top of the support column 7 and the viewing angle of the prism 8 is adjusted to complete the installation of this device. It can be used with a level and a total station to monitor the road condition.

[0028] This device utilizes the counterweight 6 at the bottom of the support column 7 to closely adhere to the original soil of the ground 1 with the cement mortar filler 4. Then, under the action of gravity, the counterweight 6 moves synchronously with the surrounding soil, thereby causing the central steel rod and the top prism 8 to move.

[0029] This device is mainly used for shallow (2~5m) displacement monitoring of existing roads such as municipal roads and highways. When used in conjunction with a high-precision total station robot, it can achieve automated real-time monitoring.

[0030] This column-mounted road prism measuring point auxiliary device, through the coordinated action of above-ground and underground fixed modules, installs the support column 7 and prism 8 on the road. This device penetrates the hardened road surface layer to measure the actual deformation of the undisturbed soil or sand layer. It can monitor and reflect the gradual failure of the roadbed working area that may be caused by changes in groundwater or karst caves, and the potential for road collapse under vehicle loads. At the same time, while ensuring road traffic safety, this device can meet the requirements of multi-directional observation of the roadbed, reduce the error of fixed points for manual measuring, ensure the accuracy of data, and improve the convenience of road monitoring and the safety of on-site operations.
