Description

Technical Field

[0001] The present application relates to the field of slope measurement, and in particular to a ruler for measuring the slope gradient. Background Art

[0002] At present, slope refers to the slope surface with a certain slope made on both sides of the roadbed to ensure the stability of the roadbed. It can be divided into artificial slope and natural slope according to the cause of formation, soil slope and rock slope according to the lithology, and permanent slope and temporary slope according to the service life. The slope gradient is an important index of slope engineering. The slope gradient refers to the ratio of the height of the slope in the vertical direction to the projection length of the slope surface in the horizontal direction.

[0003] The existing slope gradient is usually measured using a total station. To measure the slope using a total station, the total station needs to be placed on a horizontal plane and accurately horizontally calibrated. The starting and ending points to be measured are then determined, and reference markers are set between the two points. The laser transmitter of the total station is then aimed at the starting point, and a receiver is used at the ending point to receive the laser signal. Finally, the measured data is recorded and calculated to obtain the slope gradient.

[0004] The above-mentioned existing technical solutions have the following defects: the existing steps for measuring the slope gradient are relatively complicated, requiring the cooperation of multiple people, and the measurement efficiency is low. Utility Model Content

[0008] By adopting the above scheme, one side of the base plate is in contact with the slope when measuring the slope of the slope. In order to enable the measuring ruler to directly measure the slope, a sliding rod and a telescopic rod are arranged on the side of the base plate away from the slope surface, and one end of the sliding rod and the telescopic rod are both hingedly arranged on the base plate, and a connecting piece is arranged between the end of the telescopic rod away from the base plate and the sliding rod, the connecting piece is slidably connected to the sliding rod, and the connecting piece is rotatably connected to the telescopic rod. Under the action of the connecting piece, the sliding rod and the telescopic rod can both slide and rotate relative to each other, and then the telescopic rod is adjusted to make the telescopic rod in a vertical state, and then the sliding rod is adjusted to form a right angle between the sliding rod and the telescopic rod; in order to be able to directly observe the slope of the slope, a scale is arranged on the sliding rod, and a right angle is formed between the sliding rod and the telescopic rod. Through the positional relationship between the telescopic rod and the sliding rod, the corresponding value of the telescopic rod on the measuring ruler can be observed, and the slope of the slope can be observed, thereby achieving the effect of improving measurement efficiency.

[0009] Furthermore, the connecting member includes a slider and a rotating rod, the slider is sleeved on the sliding rod and is slidably connected to the sliding rod, one end of the rotating rod is fixedly connected to the slider, and the other end of the rotating rod passes through the telescopic rod and is rotatably connected to the telescopic rod.

[0010] By adopting the above scheme, when measuring different slopes, it is necessary to adjust the telescopic rod and the sliding rod so that the telescopic rod and the sliding rod are in a vertical state, and then the slope is obtained. In order to enable the telescopic rod and the sliding rod to rotate and slide relative to each other, a sliding block is sleeved on the sliding block, and the sliding block is slidably connected to the sliding block. A rotating rod is arranged between the sliding block and the telescopic rod, one end of the rotating rod is fixedly connected to the sliding block, and the other end of the rotating rod passes through the telescopic rod and is rotatably connected to the telescopic rod, so that the telescopic rod and the sliding rod can both rotate and slide relative to each other, which is convenient for adjusting the telescopic rod and the sliding rod to a vertical state under different slopes, and then completing the measurement of the slopes of different slopes.

[0016] By adopting the above solution, a horizontal bubble is fixedly connected to the telescopic rod, and the horizontal bubble is perpendicular to the outer rod. When the horizontal bubble is centered, it proves that the telescopic rod is in a vertical state.

The pointer is used to accurately read the data of the positional relationship between the telescopic rod and the sliding rod, and then accurate slope data is obtained.
