Background Technology

[0002] Generally speaking, urban roads carry the flow of goods, pedestrians, and information, serving as the lifeline of urban economic development and closely related to people's lives, work, and studies. Their condition and integrity are of great concern. In recent years, with the rapid development of urban construction, municipal road engineering has also developed rapidly. However, along with this development, many common quality problems still exist in the construction process, some of which directly affect the overall functionality of the road. For example, during road construction, various municipal pipelines are pre-buried, and inspection wells are installed at regular intervals for maintenance or control purposes.

[0003] The construction quality of road manhole projects directly affects road safety and comfort, and also impacts the city's appearance and overall image. However, in daily life, manholes on urban roads often experience subsidence or uneven installation, affecting the overall road appearance and driving comfort. Vehicles often experience a bumpy ride when approaching manhole covers, significantly reducing driving comfort. Furthermore, due to the different construction processes of asphalt concrete pavements, controlling the installation elevation and angle of manhole rings and covers becomes a key and challenging aspect of the installation work.

[0004] Currently, Chinese utility model patent CN219869372U discloses a simple pile hole positioning verification component, including: a positioning detection frame, placed above the opening of the pile hole for installing a positioning verification component; and a positioning verification component comprising: a cross positioning support, detachably mounted on the positioning detection frame; and a verification ring, annularly connected to the cross positioning support for verifying the pile hole.

[0100] In this utility model, if the locking member 23 is a bolt, the bolt passes through the first positioning rod connecting hole 211 and is threaded into the second positioning rod connecting hole 221; if the locking member 23 is a bolt and a nut, the bolt first passes through the first positioning rod connecting hole 211, is threaded and securely connected into the second positioning rod connecting hole 221, and is then securely connected together at the end of the bolt by a nut; another structure of the locking member 23 is that the lower section has a threaded section, the middle part of the locking member 23 is hollow, and four connecting plates are circumferentially connected inside the hollow part.

[0106] Fastening assembly 44 is connected to the end of the height auxiliary measuring ruler 43 located inside the height measuring sleeve 41, and both ends of the fastening assembly 44 are located outside the two adjustment ports 411.

[0116] In summary, a more specific embodiment of this utility model is as follows:

[0117] Example 1: First method for measuring the center position of well ring 71 or well cover 72

[0118] When using this utility model to measure the center position of the well ring 71 or well cover 72, the operator first places the positioning plate 1 on top of the well cover 7, then places the measuring frame 2 on top of the positioning plate 1, and makes the pipe level 6 horizontal. At the same time, the ends of the first positioning rod 21 and the second positioning rod 22 are flush with the outer periphery of the positioning plate 1. Then, the operator releases each locking piece 5 and moves each horizontal auxiliary measuring ruler 3 outward. Subsequently, the operator rotates the height measuring component 4 so that the lower end of the height measuring component 4 contacts the outer wall of the well ring 8. Finally, when the extension scales of each horizontal auxiliary measuring ruler 3 are consistent, the center of the lower part of the locking piece 23 is the center position of the well ring 71 or well cover 72. The operator can mark the locking piece 23 with a marker to obtain the center position of the well ring 71 or well cover 72.

[0119] Example 2: Second method for measuring the center position of well ring 71 or well cover 72

[0120] This embodiment 2 is the same as embodiment 1, except that, as Figures 12 to 20 As shown, when the locking member 23 has a threaded section at the bottom and the middle part of the locking member 23 is hollow, four connecting plates are circumferentially connected inside the hollow part, and the four connecting plates are in a cross shape; then when using the internally hollow locking member 23, the center position of the four connecting plates is the center position of the well ring 71 or the well cover 72.

[0121] During the above measurement process, the outer diameter of the well ring 8 can be determined by adding the length of the first positioning rod 21 or the second positioning rod 22 to the extension length of the two horizontal auxiliary measuring rulers 3.

[0122] Example 3: The third method for measuring the center position of the well ring 71 or well cover 72

[0123] In this embodiment 3, the operator can also place the measuring frame 2 on the manhole cover 7 and keep the pipe level 6 in a horizontal position. By using either the first positioning rod 21 or the second positioning rod 22, along with two corresponding horizontal auxiliary measuring rulers 3, the diameter of the manhole cover 7 can be measured first. The radius of the manhole cover 7 can be obtained by dividing the measured diameter of the manhole cover 7 by 2, and the center of the manhole cover 7 can be determined.

[0124] Example 4: Measuring the angles of manhole ring 71 and manhole cover 72 in relation to road slope

[0125] In this embodiment 4, the angle of the manhole cover and the road slope represent the ratio of the vertical height difference Δh between the two points to the horizontal distance L.

[0126] During use, the operator first determines the road slope using the design drawings, places the manhole cover measuring device on the manhole casing or the concrete cover of the manhole 7, ensures the measuring frame 2 is level using the tubular level 6, then measures the height of two points along the road's direction using the height measuring component 4 and subtracts the height difference to obtain the vertical height difference Δh. Next, the radius of the manhole ring or cover is determined using the measuring frame 2 to obtain the horizontal distance L, which is then calculated using the formula:

[0127] i 纵 =Δh / L×100%

[0128] The existing slope is determined and compared with the road slope. If they are inconsistent, the height measurement component 4 can be used to determine how much the front or rear point of the manhole ring 71 or manhole cover 72 needs to be raised or lowered.

[0129] Example 5: Measurement of the height of well ring 71 relative to the road surface

[0130] In use, the operator first loosens each locking piece 5, then moves each horizontal auxiliary measuring ruler 3 outward, and then rotates each height measuring component 4 so that the lower end of the height measuring component 4 contacts the end of the manhole ring 71. Next, the operator adjusts each height measuring component 4 to be slightly higher than the road surface, and then adjusts the pipe level 6 to a horizontal state. At this time, the operator can use the height measuring sleeve 41 and the height auxiliary measuring ruler 43 to complete the height values ​​in four directions. The four values ​​are the height values ​​of the manhole ring and the road surface at four positions. After the measurement is completed, the subsequent installation and construction work can be carried out.

[0131] In this utility model, the positioning plate 1 is used in conjunction with the measuring frame 2 and the horizontal auxiliary measuring ruler 3 and the height measuring component 4 to complete and determine the angle of the existing well ring or well cover.

[0132] When using it, after determining the center of the manhole cover, you can directly align the locking piece 23 with the center of the manhole cover and place it directly on the manhole cover.

[0133] During the above-mentioned operation, when in use, the bottom of the four height measuring components 4 at the end of the measuring frame 2 is in contact with the roadbed on the existing manhole ring or manhole cover, and the height of the four height measuring components 4 is adjusted to keep the two tube levels 6 in a horizontal state.

[0134] During use, whether on the roadbed or surface layer, during backfilling or paving, surveyors can use the manhole cover measuring device at any time to measure and verify the manhole ring or cover. This effectively prevents uneven installation of manhole covers, ensuring project quality. At the same time, the device has a simple structure, is easy to install and disassemble, has lightweight components, is convenient to transport, and can be used for a long time.

[0135] During the above-mentioned implementation process, the manhole cover measuring device can detect data such as the angle and height of the manhole cover. The diameter of the positioning plate 1 is made according to the actual size of the manhole ring or cover to be measured.

[0136] As time goes by and the measurement work is completed, the operator only needs to clean and disassemble the utility model and then transport it to the designated tool storage location by means of appropriate handling equipment or by manual labor for storage, so that it can be reused next time.

[0137] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
