Description

Technical Field

[0001] The utility model relates to a slope ratio measuring ruler used for the construction and acceptance of road subgrade slopes. Background Art

[0002] During the construction of road subgrade and cutting slopes, due to the complex construction conditions on site, the slope gradient control must always pay attention to the position of the slope top and slope foot. The workload is large during the implementation process, and surveyors are required to observe continuously to reduce errors and prevent situations such as insufficient filling width and slope foot exceeding the filling range.

[0003] During roadbed and cutting construction, the slope ratio (ratio of vertical height to horizontal height) is usually marked. Conventional design slope ratios are 1:0.5, 1:0.75, 1:1, 1:1.5, 1:2, 1:2.5, 1:3, etc.

[0004] At present, the use of measuring instruments to control the slope gradient during slope construction is labor-intensive, and ordinary angle rulers are not convenient for determining the slope ratio. Summary of the invention

[0005] The technical problem to be solved by the utility model is to provide a slope ratio ruler for road slope construction and acceptance, which solves the problem that the workload of measuring instruments is large during the current slope construction process and ordinary angle rulers are inconvenient for determining the slope ratio.

[0006] The purpose of the utility model is achieved as follows: it includes a horizontal ruler arm and a rotating ruler arm, the front end of the horizontal ruler arm and the front end of the rotating ruler arm are connected by a rotating shaft, the opening angle of the horizontal ruler arm and the rotating ruler arm can be adjusted by the rotating shaft, and the range of motion of the rotating ruler arm relative to the horizontal ruler arm is 0° to 180°; a horizontal bubble is fixed in the middle of the upper surface of the horizontal ruler arm, an annular scale is fixed on the outer circumference of the rotating shaft, and a conventional slope ratio scale is provided on the surface of the lower half of the scale;

[0007] A triangular arrow is provided on the rotating ruler arm near the dial, and the opening angle ratio is indicated by the triangular arrow pointing to the slope ratio scale on the dial;

[0008] The lower half of the dial is provided with a protractor scale within the angle range of 0° to 180° with an accuracy of 1°, wherein 0° is located at the rear end of the horizontal center line of the dial and 180° is located at the front end of the horizontal center line of the dial.

[0010] The elastic rope sleeve is sleeved on the horizontal ruler arm, and the lower end of the elastic rope connected to the elastic rope sleeve is connected with a pointed hammer ball.

[0011] A red laser emitting light is fixed on the end of the horizontal ruler arm and the rotating ruler arm away from the rotating shaft, which shines in the direction of the extension line of the ruler arm center line. When the slope measuring ruler needs to be used to better check the slope, the switch of the red laser emitting light can be turned on. There are two red laser emitting lights on the horizontal ruler arm, one of which shines forward and the other shines backward. When both red laser emitting lights are turned on, the red laser emitted will form a straight line. There is a unidirectional red laser emitting light on the rotating ruler arm, and the irradiation direction is to shine backward along the rotating ruler arm. A red laser emitting light is set at the axis position of the left and right sides of the rotating shaft.

[0016] Combine the following Figure 1-3 Further explain the utility model;

[0017] It comprises a horizontal ruler arm 1 and a rotating ruler arm 2. The front end of the horizontal ruler arm and the front end of the rotating ruler arm are connected through a rotating shaft 3. The opening angle of the horizontal ruler arm and the rotating ruler arm can be adjusted through the rotating shaft. The movable range of the rotating ruler arm relative to the horizontal ruler arm is 0° to 180°. A horizontal bubble 4 is fixed in the middle of the upper surface of the horizontal ruler arm, and an annular scale plate 5 is fixed on the outer circumference of the rotating shaft. A conventional slope ratio scale 6 is provided on the surface of the lower half of the scale plate.

[0018] The rotating ruler arm is provided with a triangular arrow 7 near the dial, and the opening angle ratio is indicated by the triangular arrow pointing to the slope ratio scale on the dial;

[0019] The lower half of the dial is equipped with a protractor scale 8 within the angle range of 0° to 180°, with an accuracy of 1° (the horizontal ruler arm and the rotating ruler arm are fully folded to 0°, and fully opened to 180°), where 0° is located at the rear end of the horizontal center line of the dial, and 180° is located at the front end of the horizontal center line of the dial. The protractor scale on the dial can be used to measure angles that are not commonly used design slope ratios. For example, if the design drawing designs a slope of 30°, just turn the triangle arrow on the ruler arm to the 30° position on the protractor scale.

[0020] The horizontal ruler arm and the rotating ruler arm are both provided with meter ruler length scales, and can be used as a ruler after being folded and opened; the length of the horizontal ruler arm and the rotating ruler arm are both 1m.

[0021] The elastic rope loop 9 is put on the horizontal ruler arm, and the lower end of the elastic rope connected to the elastic rope loop is connected to the sharp hammer ball 10. When the ruler is used, the position of the elastic rope loop can be adjusted horizontally. When the sharp hammer ball coincides with the lower end of the rotating ruler arm, the horizontal distance corresponding to the 1m slope length can be quickly converted.

[0022] A red laser emitting lamp 11 is fixed at one end of the horizontal ruler arm and the rotating ruler arm away from the rotating shaft, which is irradiated in the direction of the extension line of the ruler arm center line. When the slope measuring ruler needs to be used to better check the slope, the switch of the red laser emitting lamp can be turned on. There are two red laser emitting lamps on the horizontal ruler arm, one of which irradiates forward and the other irradiates backward. When both red laser emitting lamps are turned on, the red laser emitted will form a straight line, which can be equivalent to the horizontal reference straight line. There is a unidirectional red laser emitting lamp on the rotating ruler arm, and the irradiation direction is to irradiate backward along the rotating ruler arm. A red laser emitting lamp is respectively provided at the axis position of the left side and the right side of the rotating shaft. When the two red laser emitting lamps are turned on, red lasers can be emitted in two opposite directions to form a straight line, which is equivalent to a horizontal reference straight line perpendicular to the ruler surface direction, so as to check whether the straight line line is straight (when the roadbed is a straight section roadbed, the laser straight line is parallel to the roadbed direction, so as to check whether the straight roadbed is built straight). The charging method of the 5 red laser emitting lamps is to connect the SUB charging port of the data cable, and the charging socket is set on the side of the turntable.

[0023] How to use: Assuming that the design slope ratio of the conventional section is 1:1.5, after the base bed is layered and compacted and settled, prepare to carry out the slope brushing construction. After the construction personnel determine the top of the slope, they command the excavator to trim the slope, open the horizontal arm and the rotating arm of the ruler through the shaft, read the 1:1.5 angle on the dial and fix it (the arms are tightly connected to the shaft and can be fixed by friction, and the rotating arm requires a lot of force to rotate). Place the horizontal arm horizontally and ensure that the upper horizontal bubble tube is horizontal. Observe whether the rotating arm and the slope overlap to check the slope trimming condition. When the rotating arm and the slope completely overlap, it means that the slope is in good condition.

[0024] The use of a rope loop and a sharp hammer ball can be used to evaluate the slope repair effect. Put the elastic rope loop on the horizontal ruler arm, adjust the horizontal position of the elastic rope loop left and right, and tie a sharp hammer ball to the lower end of the rope. When the hammer ball coincides with the lower end of the rotating ruler arm, the horizontal distance corresponding to the 1m slope length can be quickly converted. Then the accuracy of the slope measurement can be verified by trigonometric functions.

[0025] In order to better check the entire slope, turn on all three red laser lights on the ruler arm to more intuitively check the entire slope. Turn on all two red laser lights on the shaft to check the vertical relationship between the slope and the line and whether the straight line is straight.
