Technical Field

[0001] The utility model belongs to the field of slope construction survey, and particularly relates to a slope measuring device for highway subgrade design. Background Technique

[0002] The subgrade slope refers to the transition area between the ground on both sides of the road and the subgrade. Its main function is to maintain the stability of the subgrade, prevent soil erosion and landslides. It is an important factor affecting the stability of the subgrade. The shape of the slope is often built into a single slope, a broken line shape and a stepped shape in the subgrade. In the process of civil engineering construction, engineering survey is indispensable and plays a crucial role in the accuracy of engineering construction. To meet the stability requirements, there are free surfaces with a certain slope in the design of buildings such as road subgrades, the upstream and downstream surfaces of reservoirs (dikes), and the upstream surfaces of ditches. However, in the specific implementation process of detection, whether the slope angle of the slope reaches the design requirements must be determined through the measurement of the current slope.

[0003] The slope measurement generally uses the side line lofting to determine the width and the elevation measurement to determine the height, and controls the slope according to the height-width ratio of the highway subgrade construction. This method has a slow detection speed, requires a large number of tools such as tower rulers and tape measures, and requires about 3 people to cooperate in the measurement. It takes a long time, has a slow speed, requires a lot of labor, is only suitable for the pre-construction setting-out work, is not conducive to the real-time monitoring of the slope during the later construction, and is not convenient to carry. Content of the Utility Model

[0005] The slope measuring device for highway subgrade design includes a storage box without a top surface. A storage groove is opened along the length direction of the bottom of the storage box. A plurality of pins that can swing in and out at an angle are hinged in the storage groove. A limiting component for limiting the swinging angle of all the pins is arranged on all the pins. Side plates for fitting with the slope surface are horizontally fixed on both side walls in the length direction of the storage box. A vertical rod that can swing freely at an angle and can be stored in the storage box is hinged on the storage box. A display component for displaying the slope angle is arranged between the vertical rod and the storage box; a level for displaying its vertical state is installed on the swinging end of the vertical rod.

[0006] Further, the limiting component includes a stop block. The stop block is fixed on the hinged end of the pin. When the pin swings to be perpendicular to the storage box, the stop block fits with the bottom of the storage groove.

[0007] Further, a connecting seat is fixed on the hinged end of the vertical rod, and two mounting seats spaced and aligned along the width direction are fixed on the top of the storage box. The connecting seat is located between the two mounting seats.

A screw is inserted through the through hole and the threaded hole, and the threaded end of the screw is in threaded fit with the threaded hole.

[0008] Further, the display component includes angular scale lines which are arranged on both side walls in the length direction of the vertical rod with the hinge point as the center of the circle, and an opening for aligning the angular scale lines and viewing the values is formed on the top of the storage box.

[0009] Further, scale lines for measuring length are arranged on both side walls in the length direction of the vertical rod.

[0023] The present utility model will be further described below with reference to the accompanying drawings through specific embodiments, but it is not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present invention.

[0024] Embodiment 1

[0025] A slope measuring device for highway subgrade design described in this embodiment, as shown in Figure 1 , Figure 4 and Figure 5 , includes a storage box 7 without a top surface. The cross-section of the storage box 7 is in a rectangular structure, and the box opening of the storage box 7 faces upward;

[0026] A storage groove is provided at the bottom of the storage box 7 along its length direction. A plurality of pins 6 that can swing in and out at an angle are hinged in the storage groove. In this embodiment, there are five groups of pins 6. All the pins 6 are hinged in the storage box 7 through a pivot. A perforation for the pivot to pass through is provided at one end of each pin 6. Both ends of the pivot are fixed on the two groove walls in the length direction of the storage groove, so that the pins 6 can swing in and out and be stored in the storage groove, thereby reducing the occupied space and facilitating the staff to carry; of course, it can also be hinged through a bearing. The inner ring of the bearing is fixed to the pin 6, and the outer ring of the bearing is fixed to one of the groove walls in the length direction of the storage groove; after the pins 6 are swung out, when the storage box 7 fits the slope surface of the slope, they can be inserted into the soil of the slope surface, so that the storage box 7 can be fixed on the slope surface of the slope;

[0027] For further explanation, as shown in Figure 1 , Figure 5 and Figure 6As shown, preferably, a stop block is included in this embodiment. The stop block is fixed to the hinged end of the pin 6. When the pin 6 swings to be perpendicular to the storage box 7, the stop block fits against the bottom of the storage groove; the end faces of the hinged ends of all the pins 6 are semi-circular, and the hinge points are aligned with the central axis of the semi-circle. The stop block is fixed to the end face of the hinged end of the pin 6. When the pin 6 swings to a state perpendicular to the storage box 7, the stop block will fit against the bottom of the storage groove, thereby blocking and restricting the swinging angle of the pin 6. When the staff uses it, it can make it more convenient for the staff to quickly swing the pin 6 to be perpendicular to the storage box 7, saving the time for taking out the pin 6; this solution as a whole constitutes a limiting component for limiting the swinging angle of the pin 6; of course, the limiting component can also adopt a retaining rod. The two ends of the retaining rod are fixed to the two side walls in the length direction of the storage groove. The retaining rod is located on one side of the pin 6. When the pin 6 swings to a state perpendicular to the storage box 7, the retaining rod will block the pin 6 and block and restrict the swinging angle of the pin 6.

[0028] On the two side walls in the length direction of the storage box 7, side plates 12 for fitting against the slope are horizontally fixed; the bottoms of the two side plates 12 are flush with the bottom of the storage box 7, so that when the bottom of the storage box 7 fits against the slope, the bottoms of the two side plates 12 will also fit against the slope. By means of the two side plates 12, the contact area with the slope is increased, enabling the storage box 7 to fit more stably on the slope and not easily tilt or fall over.

[0029] A vertical rod 3 is hinged to the storage box 7. The vertical rod 3 can swing freely at an angle and can be stored in the storage box 7. The hinge point is flush with the top of the storage box 7. In this embodiment, the vertical rod 3 is hinged to the storage box 7 by screws. A connecting seat 9 is fixed on the hinged end of the vertical rod 3. The connecting seat 9 is disc-shaped and is located at the corner of the hinged end of the vertical rod 3. Two mounting seats 8 are fixed on the top of the storage box 7 and are spaced and aligned along its width direction. The two mounting seats 8 are located at one end of the top of the storage box 7. The connecting seat 9 is located between the two mounting seats 8. The two mounting seats 8 are aligned with the axis of the connecting seat 9, and the connecting seat 9 is in contact with the two mounting seats 8. A threaded hole is provided in one of the mounting seats 8, and through holes aligned with the axis of the threaded hole are provided above the other mounting seat 8 and the connecting seat 9. A screw is inserted through the through hole and the threaded hole. The threaded end of the screw is in threaded engagement with the threaded hole. By rotating the screw, the two mounting seats 8 can squeeze the connecting seat 9. The greater the squeezing force of the two mounting seats 8 on the connecting seat 9, the greater the friction between the two mounting seats 8 and the connecting seat 9, thereby playing a certain locking role on the swung vertical rod 3. After the vertical rod 3 swings to the required position, it can self-position at the swung position, which is convenient for the staff to solve other things on the way. And after the vertical rod 3 swings and is stored in the storage box 7, the vertical rod 3 is not easy to swing out of the storage box 7, which is more convenient for the staff to store and carry. Of course, a damping rotating shaft can also be used between the vertical rod 3 and the storage box 7. One end of the damping rotating shaft is fixed on the hinged end of the vertical rod 3, and the other end of the damping rotating shaft is fixed on the inner box wall of the storage box 7, so that the vertical rod 3 can be kept stable at the swung position through the damping rotating shaft;

[0030] A pull ring 1 for conveniently taking it out is fixed on the swinging end of the vertical rod 3. When the vertical rod 3 swings and is stored in the storage box 7, the staff can pull the pull ring 1 by hand to pull the vertical rod 3 out of the storage box 7, which is convenient for the staff to take and place the vertical rod 3;

[0031] Dimension scale lines for measuring length are provided on both side walls in the length direction of the vertical rod 3. When the staff needs to measure the size of an object, the vertical rod 3 can be aligned with the object, and the size of the object can be measured through the dimension scale lines on the vertical rod 3;

[0032] For further explanation, such as Figure 3 、 Figure 4 and Figure 6As shown in the figure, preferably, the present embodiment includes angular scale lines 11 which are provided on both side walls in the length direction of the vertical rod 3 with the hinge point as the center. An opening 13 for aligning with the angular scale lines 11 and viewing the values is provided at the top of the storage box 7. When the vertical rod 3 is stored in the storage box 7, the zero point on the angular scale lines 11 is flush with the bottom of the opening 13. When the vertical rod 3 swings, the vertical rod 3 will drive the angular scale lines 11 to rotate around the hinge point. When the vertical rod 3 swings to the vertical state, the staff can view the angular scale line 11 line aligned with the bottom of the opening 13 through the opening 13, and the slope angle can be obtained by calculation. The whole scheme constitutes a display component for displaying the slope angle. Of course, the display component can also adopt a protractor. The protractor is fixed on the vertical rod 3 through a connecting rod, and the center point of the protractor is aligned with the hinge point on the vertical rod 3. A pointer aligned with the hinge point on the vertical rod 3 is fixed on the side wall of the storage box 7. When the vertical rod 3 swings, it will drive the protractor to rotate. When the vertical rod 3 swings to the vertical state, the pointer will point to the corresponding line or value on the protractor.

[0033] A spirit level 2 for displaying its vertical state is installed on the swinging end of the vertical rod 3. The spirit level 2 is a tool for measuring whether an object or surface is in a horizontal state. It usually consists of a transparent tube filled with liquid (usually alcohol or water) and a bubble. When the spirit level is in the horizontal position, the bubble will be located on the center scale line of the tube. The spirit level is widely used in fields such as construction, engineering, and machining to ensure the levelness of equipment, structures, or surfaces, thereby guaranteeing the work quality and safety. Through the spirit level 2, it can be clearly and intuitively reflected whether the vertical rod 3 is in a vertical state, making the slope angle measurement more accurate.

[0034] A number of sewage discharge holes 4 communicating inside and outside are provided on both side walls in the length direction of the storage box 7. After the storage box 7 is used for a long time, a lot of soil and impurities will accumulate in the storage box 7. The soil and impurities will occupy the space for storing the vertical rod 3, making the storage box 7 less hygienic. When flushing the inside of the storage box 7 with water, the flushed soil and impurities can be discharged from the sewage discharge holes 4 in time to avoid sedimentation of the soil and impurities in the storage box 7.

[0035] Anti-slip patterns are provided on both side walls in the length direction of the storage box 7. The anti-slip patterns can be processed by methods such as embossing, die forming, laser engraving, and chemical etching. When the staff picks up this measuring device, the anti-slip patterns can increase the friction with the skin, thus avoiding the appearance of slipping.

[0036] A hanging strap 5 is fixed on the storage box 7; the hanging strap 5 is made of materials such as rubber, cloth, leather, and plastic. The hanging strap 5 is fixed on the end face at one end of the storage box 7, which facilitates the staff to carry it. When storing, the hanging strap 5 can be hung on the hook of the wall or the shelf, which is convenient for storage and does not take up space.

[0037] During the actual use process, first swing outwards to take out all the pins 6. Under the action of the stop block, the pins 6 swing to a state perpendicular to the storage box 7. Then move the storage box 7 to the slope surface of the slope, making the storage box 7 parallel to the slope surface. Then insert all the pins 6 into the soil of the slope, and the bottom of the storage box 7 and the two side plates 12 are attached to the slope surface. The storage box 7 is fixed on the slope surface through the pins 6. Then pull out the vertical rod 3 from the storage box 7 through the pull ring 1, and swing the angle of the vertical rod 3 based on the level 2 to make the vertical rod 3 swing to the vertical state; when the vertical rod 3 is swinging, the angle scale line 11 on the vertical rod 3 rotates around the hinge point. When the vertical rod 3 swings to the vertical state, the staff can view the line of the angle scale line 11 aligned with the bottom of the opening 13 from the opening 13, and the angle of the slope can be obtained through calculation without the cooperation of multiple people, making the measurement of the slope angle more convenient; after use, all the pins 6 are put into the storage groove, and the vertical rod 3 is stored in the storage box 7, reducing the overall volume and thus being more convenient to carry.
