[0002] Terrain shaping is one of the basic tasks of greening construction. When shaping and brushing the terrain during river construction, the angle of the river slope is mostly based on the workers' personal judgment. Due to the uneven construction level of the workers, the slopes on both sides of the stone retaining wall river are irregular and unsightly, and the overall coordination is not high. At present, GPS is also used to control the slope angle, but GPS requires frequent calculations, which is heavy and cumbersome.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0020] The present embodiment comprises a telescopic vertical rod 1, a telescopic horizontal rod 6 and a telescopic diagonal rod 4 for slope control, all of which are telescopic rods with variable lengths. In the present embodiment, the telescopic vertical rod 1, the telescopic horizontal rod 6 and the telescopic diagonal rod 4 are all in the form of telescopic sleeves and can be made of aluminum square tubes sleeved together.

[0021] The outer side of the bottom of the telescopic vertical rod 1 is fixed on the side of the horizontal U-shaped support frame 2. The outer side here refers to the side away from the slope. The bottom of the U-shaped support frame 2 is provided with a roller 3, and the U-shaped support frame 2 drives the entire tool to move. In order to prevent the tool from sinking due to the heavy weight at the slope end, it is preferred that a counterweight groove 17 is provided on the upper surface of the U-shaped support frame 2. A counterweight block can be placed in the counterweight groove 17 to increase the weight of the bottom. The counterweight block is not drawn in the attached figure.

[0022] To further prevent the tool from tilting, preferably, the long horizontal support rod 11 is fixed at the top of the telescopic cross bar 6 by bolts B18, the outer end of the long horizontal support rod 11 is integrally connected to the vertical support rod 12 downward, and the lower end of the vertical support rod 12 is integrally connected to the short horizontal support rod 13, and the long horizontal support rod 11, the vertical support rod 12 and the short horizontal support rod 13 are in a C shape as a whole. The arc-shaped card slot 14 is connected to the end of the short horizontal support rod 13, and the inner side of the arc-shaped card slot 14 is slidably connected to the uppermost transverse tube 16 of the guardrail 15 at the bottom of the slope. During construction, a capping stone is generally provided at the horizontal part of the bottom of the slope, and a guardrail 15 is provided on the capping stone. The guardrail 15 is used to separate the slope and the river channel to ensure safety. The capping stone and the guardrail 15 are conventional settings at the slope and the river channel, and will not be introduced here. The present invention utilizes the guardrail 15 to prevent the tool from tilting, and also has a guiding function. In this embodiment, the upper end surface of the arc groove 14 can be placed on the upper end surface of the transverse tube 16, that is, the upper part of the arc groove 14 can wrap the upper end surface of the transverse tube 16 of the guardrail 15. In order to facilitate the arc groove 14 to be more easily connected to the transverse tube 16 from the side, the diameter of the arc groove 14 is preferably 1-3 cm larger than the diameter of the transverse tube 16.

[0023] The bottom of the telescopic vertical rod 1 is hinged to the telescopic diagonal rod 4. In this embodiment, the bottom of the telescopic vertical rod 1 is hinged to the telescopic diagonal rod 4 by a bolt C19, and nuts C20 are provided at both ends of the bolt C19. The telescopic diagonal rod 4 can rotate around the bolt C19, and the telescopic diagonal rod 4 is prevented from continuing to rotate by tightening the nuts C20. Similarly, the upper part of the telescopic vertical rod 1 is hinged to the telescopic cross bar 6 by a bolt D21, and nuts D22 are provided at both ends of the bolt D21. The telescopic cross bar 6 can rotate around the bolt D21, and the telescopic cross bar 6 is prevented from continuing to rotate by tightening the nuts D22. A level 7 is provided on the upper surface of the telescopic cross bar 6.

[0024] A fixing hole 5 is provided at the end of the telescopic diagonal rod 4, and a connecting hole 8 matching the fixing hole 5 is provided at the end of the telescopic cross rod 6. A bolt A9 passes through the fixing hole 5 and the connecting hole 8. Nuts A10 are provided at both ends of the bolt A9. The telescopic diagonal rod 4 and the telescopic cross rod 6 are fixed together by the bolt A9 and the nut A10.

[0025] When in use, first adjust the height of the telescopic vertical rod 1 so that the arc-shaped slot 14 can be slidably connected to the transverse tube 16 at the upper end of the guardrail 15. When adjusting, the inner side surface of the upper end of the arc-shaped slot 14 can be slightly higher than the upper end surface of the transverse tube 16. When the arc-shaped groove is stuck on the side of the transverse tube 16 from the side, the height of the telescopic vertical rod 1 is slightly lowered so that the upper end surface inside the arc-shaped slot 14 can be placed on the upper end surface of the transverse tube 16. After adjusting the telescopic vertical rod 1 and the arc-shaped slot 14, the telescopic cross bar 6 is rotated to make the telescopic cross bar 6 perpendicular to the telescopic vertical rod 1. The telescopic cross bar 6 is adjusted to a horizontal state according to the level 7 on the telescopic cross bar 6. At the same time, the length of the telescopic cross bar 6 is adjusted according to the slope gradient required by the design. For example, if the height and width ratio of the designed slope is 1:3, the telescopic cross bar 6 is adjusted. The length is adjusted to 3 times the height of the telescopic vertical rod 1, and then tighten the nut D to tighten the telescopic cross bar 6, rotate the telescopic diagonal rod 4, adjust the length of the telescopic diagonal rod 4, align the fixing hole 5 of the telescopic diagonal rod 4 with the connecting hole 8 of the telescopic cross bar 6, pass the bolt A9, tighten the nuts A10 at both ends, and tighten the nuts C20 at the same time so that the telescopic diagonal rod 4 can no longer rotate. At this time, the inclination angle of the telescopic diagonal rod 4 is the designed slope angle. The slope is constructed according to the angle of the telescopic diagonal rod 4. During the construction process, the U-shaped support frame 2 is continuously pushed forward. When the arc-shaped slot 14 encounters the vertical tube of the guardrail 15, it is only necessary to slightly push the U-shaped support frame 2 toward the guardrail 15, so that the arc-shaped slot 14 temporarily disengages from the horizontal ancient tube 16 and then bypasses the vertical tube, and then the arc-shaped slot 14 is slid and connected to the horizontal tube 16 again.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
