[0002] With the explosion of the global population, the development and utilization of underground space have now become an important development mode for humans to explore new lives, with great development prospects. There are two methods for the construction of underground structures: open excavation and underground excavation. As the most common construction form of open excavation, slope excavation has a very wide application in earthwork excavation construction. During the earthwork excavation process, the measurement and control of the slope angle are important construction indicators, which have a direct impact on the construction of foundation pit support, slope stability, earthwork volume, etc. Therefore, the slope angle during earthwork excavation needs to be strictly controlled.

After calculation, the slope gradient or slope angle is determined. It is okay for engineering acceptance, but it is time-consuming and laborious to control the slope angle during the construction process. Content of the Utility Model

[0032] Refer to the attached Figure 1-6 , this embodiment provides a slope cutting angle measuring device, which includes: a support 10, an angle dial 20, a rotating beam 30, and a rotating counterweight 40. A bottom plate 11, a column 12, and a mounting beam 13 are configured in the support 10. The column 12 is perpendicular to the bottom plate 11, and the mounting beam 13 is located at the top of the column 12 and is used for mounting the rotating beam 30; the angle dial 20 is arranged on the column 12 and is coaxially configured with the mounting beam 13; the rotating beam 30 is rotatably configured on the mounting beam 13, and the rotating counterweight 40 is located at the end of the rotating beam 30 and is used to drive the rotating beam 30 to rotate around the axis of the angle dial 20.

[0033] In this embodiment, the rotating beam 30 includes a first support arm 31, a second support arm 32, and a sleeve 33 connecting the two. The sleeve 33 is coaxially sleeved on the mounting beam 13. The first support arm 31 and the second support arm 32 extend in opposite directions along the same diameter of the sleeve 33, and the rotating counterweight 40 is arranged at the separated ends of the two. The matching principle for the length of the first support arm 31, the length of the second support arm 32, and the mass of the rotating counterweight 40 is: the length of the first support arm 31 × the mass of the rotating counterweight 40 on the first support arm 31 = the length of the second support arm 32 × the mass of the rotating counterweight 40 on the second support arm 32, so that under the action of the rotating counterweight 40, the first support arm 31 and the second support arm 32 always remain in a horizontal state.

[0034] When using this device to measure the slope angle of the slope, place the bottom plate 11 stably on the slope surface of the slope. At this time, the column 12 is perpendicular to the slope surface. Under the action of the gravity of the rotating counterweight 40, the first support arm 31, the second support arm 32, and the sleeve 33 rotate to maintain the balance state of the first support arm 31 and the second support arm 32, that is, the horizontal state. At this time, the included angle between the first support arm 31 or the second support arm 32 and the column 12 is the slope angle of the slope, and the angle scale on the angle dial 20 corresponding to this time can be read.

[0035] This device is convenient to move, use and measure, and is not restricted by whether the construction at the top and bottom of the slope is completed. Even when the construction of the slope is not completed, the slope angle can be checked at any time, the construction accuracy can be controlled, and rework due to problems found only at the end of the project or during quality inspection can be avoided, improving the construction efficiency and construction quality.

[0036] For convenient installation, at least two groups of columns 12 are correspondingly configured on the bottom plate 11. Sleeve the sleeve 33 on the mounting beam 13, connect the two ends of the mounting beam 13 to the top ends of the columns 12, and set the angle dial 20 at the top end of the column 12 and configure it coaxially with the mounting beam 13.

[0037] For accurate reading, in this embodiment, angle marks 50 pointing to the center of the angle dial 20 are provided on the first support arm 31 and the second support arm 32. The angle marks 50 can be in any form such as pointers, branch lines, or triangular marks, and are not limited here.

[0038] To reduce the system error, preferably: the first support arm 31 and the second support arm 32 are of equal length, and equal-mass rotating counterweights 40 are respectively arranged at the separated ends of the two.

[0039] To improve the placement stability of the bottom plate 11, a plurality of anchoring feet 14 can be provided at the bottom of the bottom plate 11. The cross-sectional dimension of the anchoring feet 14 gradually decreases in the direction away from the bottom plate 11. During use, drive the anchoring feet 14 into the slope surface so that the bottom plate 11 is in parallel contact with the slope surface.

[0040] In this embodiment, the number of the angle dials 20 can be set according to requirements, and one or two angle dials 20 can be set. If two angle dials 20 are set, the two angle dials 20 can be respectively arranged at both ends of the mounting beam 13. In this way, no matter in which direction, the angle dials 20 can be read, making the use more convenient. Two sets of symmetric two-way 0-180° angle scale lines can be set on the angle dials 20, and their zero scale lines are perpendicular to the column 12. When the first arm 31 and the second arm 32 rotate, the arm close to the slope top corresponds to the scale lines below the zero scale line, and the arm close to the slope bottom corresponds to the angle lines above the zero scale line. However, since the first arm 31 and the second arm 32 extend in opposite directions along the same diameter of the sleeve, the angle lines corresponding to the above two arms have the same reading, and the reading of either arm can be used, making the use more convenient.

[0041] Compared with the prior art, the beneficial effects of the present utility model are as follows: it is convenient to move, use and measure, and is not restricted by whether the construction at the slope top and the slope bottom is completed or not. Even when the construction of the slope is not completed, the slope angle of the slope can be checked at any time, the construction accuracy can be controlled, and rework due to problems found only at the end of the project or during quality inspection can be avoided, improving the construction efficiency and construction quality; the configuration of the first arm 31 and the second arm 32 enables the measurement and reading of the device to be carried out bidirectionally, without the need to specifically distinguish the positive and negative directions during use, making the use more convenient.

[0042] The above is the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
