[0002] During the construction of the road surface and roadbed, in order to ensure that the width of the constructed road surface meets the construction standards, side piles will be installed on both sides of the road surface and roadbed. The side piles are wooden stakes that mark the intersection of the roadbed slope line and the ground in each cross section on the ground. When installing the side piles, the position of the side piles needs to be located.

[0003] Therefore, a roadbed and pavement construction side pile positioning device in the prior art has a publication number of CN217629312U. The rod body is inserted into the ground at the positioning point, and the steel strand is fixed on the hanging block. The distance between the steel strands of two adjacent rod bodies is adjusted by sliding the slider to adjust the tension of the steel strand. When the slider is slid, the spring is stretched to form a certain tensioning force. Even if the steel strand is extended or relaxed to a certain extent, the hanging block can still be driven by the spring to slide toward the side close to the rod body to keep the steel strand in a straightened state, which is convenient for calibrating the height of the cast pavement.

[0004] However, the steel strand is an independent component, that is, it is independently arranged from the rod body. Therefore, when using it, it is necessary to cut the steel strand to a corresponding length according to the width of the road surface, and the installation and recovery of the steel strand is not very convenient.

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] like Figure 1-5 As shown, a side pile positioning device for roadbed and road surface construction includes a steel strand 6 and a plurality of plug posts 4 inserted into the ground, the top of the plug posts 4 is fixedly connected to a leveling seat 3, the upper surface of the leveling seat 3 is rotatably connected to a rotating seat 1, the rotating seat 1 is rotatably connected to a screw rod 8, the top of the screw rod 8 penetrates the rotating seat 1 and extends outward, and the screw rod 8 is threadedly connected to a lifting block 7 sleeved on the rotating seat 1 along the longitudinal direction, as shown in FIG. Figure 1 As shown, two double-columnar protrusions are provided on the rotating seat 1, and the screw rod 8 is parallel to the two columnar protrusions and is located between the two columnar protrusions. As can be seen from the figure, the lifting block 7 is sleeved on the two columnar protrusions of the rotating seat 1, and the screw rod 8 threadedly connected to the lifting block 7 is rotated in turn. With the assistance of the columnar protrusions, the lifting block 7 is lifted and lowered for height adjustment, and then after the plug column 4 is plugged in and the leveling seat 3 is leveled, the height of the steel strand 6 passing through the lifting block 7 can be adjusted by adjusting the height of the lifting block 7. The height of the steel strand 6 is used as a reference for the thickness of the foundation and bottom surface construction. A winding drum 16 for winding and reeling the steel strand 6 is installed on one of the rotating seats 1. One end of the strand 6 passes through the top and bottom edges of the side of the lifting block 7 respectively, and the lifting block 7 and the penetration position of the steel strand 6 are staggered. The steel strand 6 can be released by rotating the winding drum 16, so that the steel strand 6 can pass through several lifting blocks 7 located on one side of the road surface and the roadbed in turn. After the construction is completed, it is only necessary to rotate the winding drum 16 to wind up the steel strand 6. When detecting the surface flatness of the road surface and the roadbed, it is only necessary to fix the winding drum 16 on one of the rotating seats 1, and the steel strand 6 in the winding drum 16 passes through the lifting block 7 on the same rotating seat 1, and then passes through a lifting block 7 located on the other side of the roadbed and the road surface. The steel strand 6 can be used to visually inspect the surface flatness of the road surface and the roadbed.

[0024] In order to ensure that the steel strand 6 is in a taut state when it expands and contracts due to heat: a number of spring rods 9 are fixedly connected to the side of the lifting block 7, and the telescopic end of the spring rod 9 is fixedly connected to a limiting member 10. The limiting member 10 is arranged in a "concave" shape, and the concave part of the limiting member 10 is used to clamp with the steel strand 6. When the steel strand 6 passes through the top plate and the bottom edge of one side of the lifting block 7, it is simultaneously clamped in the concave part of the limiting member 10, and pressure is applied to the limiting member 10 through the taut steel strand 6, so that the spring rod 9 connected to the limiting member 10 is in an elastically compressed state. Therefore, when the steel strand 6 is loosened due to human or natural reasons during use, the compressed spring rod 9 is elastically stretched to realize the movement of the limiting member 10, and the limiting member 10 is used to straighten the loose steel strand 6 to ensure that the steel strand 6 is in a taut state.

[0025] In order to ensure that the heights of the lifting blocks 7 at two adjacent positions at the same height are aligned: the opposite surfaces of the two adjacent lifting blocks 7 are respectively fixedly connected with the laser pen 11 and the reflector 15. When the pillar 4 is installed on the horizontal road surface, the height of one of the two adjacent lifting blocks 7 is adjusted first, and the height of the other lifting block 7 is adjusted until the laser of the laser pen 11 on one of the lifting blocks 7 is located at the center of the reflector 15 on the other lifting block 7, which means that the two adjacent lifting blocks 7 at the same horizontal height are at the same height position.

[0026] In order to adjust the angle of the leveling seat 3 according to the inclination of the road surface: a number of bubble levels 2 distributed in a circular array are fixedly connected to the upper surface of the leveling seat 3, a number of sliders 13 are inserted into the bottom edge of the leveling seat 3, a screw rod 14 is fixedly connected to the bottom surface of the slider 13, a sleeve 12 is threadedly connected to the screw rod 14, an auxiliary plug 5 for plugging into the ground is rotatably connected to the outer end surface of the sleeve 12, the screw rod 14 swings toward the direction of the plug 4, and the cross section of the auxiliary plug 5 is multi-edge-shaped. Specifically, when the plug 4 is inserted into the ground, the insertion direction may be tilted. Therefore, the bubble level 2 set on the leveling seat 3 can be used to determine the tilt direction of the leveling seat 3. At this time, in order to adjust the leveling seat 3, the slider 13 is moved, as shown in the figure, so that the slider 13 rotates around the plug post 4 to adjust the position, that is, the slider 13 is adjusted to the tilt direction of the leveling seat 3, and then the auxiliary cuttings 5 ​​are inserted into the ground, and by rotating the sleeve 12, the threaded connection between the sleeve 12 and the screw rod 14 is utilized to realize the movement of the screw rod 14 in the sleeve 12, and the rotational connection between the sleeve 12 and the auxiliary cuttings 5 ​​and the rotational connection between the screw rod 14 and the slider 13 are utilized to realize the slider 13 driving the corresponding position of the leveling seat 3 to swing and tilt, and adjust the inclination of the leveling seat 3, that is, adjust the inclination of the plug post 4 and the rotating seat 1, so that the rotating seat 1 is perpendicular to the road surface and roadbed.

[0027] The working principle is to insert a number of plugs 4 into both sides of the road surface and the roadbed. After the plugs 4 are installed, the inclination direction of the leveling seat 3 is determined according to the bubble position of the bubble level 2, and then the slider 13 is used and the auxiliary cuttings 5 ​​are inserted into the ground, and then the inclination of the leveling seat 3 is adjusted by rotating the sleeve 12, that is, the inclination of the rotating seat 1 is adjusted, and then the screw 8 is rotated to adjust the height of the lifting block 7, and the winding drum 16 is fixed on one of the rotating seats 1. The steel strand 6 in the winding drum 16 passes through the lifting block 7 on the same rotating seat 1, and then passes through a lifting block 7 on the roadbed and the other side of the road surface. The steel strand 6 can be used to visually inspect the flatness of the road surface and the roadbed surface.

[0028] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
