Technical Field

[0001] The utility model relates to the technical field of elevation measurement, in particular to an inspection well elevation testing device. Background Art

[0002] Inspection wells are an indispensable part of urban underground infrastructure, mainly serving the maintenance and installation of various pipelines such as power supply, water supply, drainage, sewage, communication, cable TV, gas pipes, street light lines, etc. These well-shaped structures are usually set up at pipeline intersections, bends, places where pipe diameters or slopes change, and at regular intervals on straight pipe sections to facilitate regular inspection, maintenance and cleaning.

[0003] During the pipeline construction process, measuring the elevation of the inspection well can guide the construction personnel to install and lay the pipeline according to the design requirements. This helps to ensure that the slope, depth and other parameters of the pipeline meet the design requirements, thereby ensuring the normal operation and service life of the pipeline. In addition, elevation measurement is one of the important means of quality control. By regularly measuring the elevation of the inspection well, deviations and errors in construction can be discovered in time, and corresponding measures can be taken to correct and adjust them. This helps to ensure that the quality of the project meets the requirements of relevant standards and specifications.

[0004] Commonly used measurement methods include ruler measurement (selecting a fixed point above the wellhead or equipment as a reference point, and using a ruler or measuring ruler to measure the height difference from the reference point to the top of the wellhead or equipment) and level measurement (determining the elevation of the wellhead or equipment by measuring the elevation difference at different locations). The operation process is cumbersome and requires cooperation from multiple people. Utility Model Content

[0023] To illustrate the features of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments.

[0024] Example:

[0025] See also Figure 1 to Figure 2 The utility model provides an inspection well elevation inspection device, including a 3-meter-long ruler 1 and two movable clamping bases 2. The two movable clamping bases 2 respectively clamp the two ends of the ruler 1, and the two ends of the ruler 1 can move up and down in the movable clamping bases 2.

[0026] In this embodiment, the mobile clamping base 2 includes a base plate 21, a clamping member 22 and two universal wheels 23. The clamping member 22 is fixedly arranged at the upper end of the base plate 21, and the universal wheels 23 are fixedly arranged at the lower end of the base plate 21. To ensure the accuracy of the measurement, the clamping member 22 is perpendicular to the base plate 21, and a ruler 24 is arranged on the side of the clamping member 22 to help the operator quickly determine the height of the end of the ruler 1. Specifically, the size marked on the ruler 24 is the vertical distance from the bottom end of the universal wheel 23. When in use, the operator adjusts the two ends of the ruler 1 to the same height in advance.

The L-shaped clamps on both sides are not connected to each other and are fixedly connected to the base plate 21 respectively. The opening side without the horizontal plate corresponds to the ruler 1 inwardly. The ruler 1 is placed in the L-shaped clamp and is clamped by the elasticity of the L-shaped clamp itself without affecting the up and down movement of the ruler 1 inside. In order to facilitate the operator to read, the sides of the L-shaped clamp are provided with rulers 24.

[0028] The method of using this embodiment is as follows:

[0029] Determine the design height of the inspection well according to the design, place the inspection well elevation inspection device on the horizontal ground, adjust the height of ruler 1 so that the height of ruler 1 from the ground is adjusted to the design height of the inspection well, and then push the inspection well elevation inspection device through each inspection well to measure the height difference between the top surface of the inspection well and the bottom surface of the ruler when passing through the inspection well. It is qualified when the height difference is ±5mm, and the rest is unqualified.
