Description

Technical Field

[0001] The utility model relates to the technical field of road construction, in particular to a road construction pile. Background Art

[0002] During road construction, road stakes are usually needed to separate the road sections that need to be constructed, which can effectively restrict vehicle access and control the direction and route of passing vehicles, thereby managing and controlling the traffic at each entrance and exit;

[0003] Chinese patent authorization announcement number CN211368512U discloses a road pile for road construction, including a central axis, a semicircular fixed pile welded on the surface of the central axis, a shock-absorbing spring movably sleeved on the surface of the semicircular fixed pile, a threaded fixed pile fixedly sleeved on the end of the shock-absorbing spring away from the central axis, a shell movably sleeved on the surface of the central axis, a protective sleeve movably sleeved on the surface of the shell, and a shock-absorbing spring movably sleeved on the internal part of the road pile for road construction. When the internal shock-absorbing spring is damaged, it can be replaced by a threaded fixed pile, solving the problem of inconvenient inspection and replacement of road piles. The protective sleeve is made of polyurethane with buffering properties, which can reduce the damage to pedestrians and vehicles in the event of an accident;

[0004] The above-mentioned existing technical solution has the following shortcomings: when the technical solution is in use, it fixes the base and the embedded part on the road surface. When a moving vehicle collides with the road post, the impact force on the shell is reduced only by the contraction deformation and elastic potential energy of the shock-absorbing spring. During use, the stability between the road post and the ground cannot be guaranteed, so further improvement is needed. Utility Model Content

One side below the telescopic sleeve rod 15 is connected with a hinge block 18, and one end of the hinge block 18 is hinged with a barb 11. There are three groups of barbs 11, and the barbs 11 are distributed in a ring shape on the outside of the telescopic sleeve rod 15. One end of the barb 11 penetrates through the inside of the hole 12 and extends to the outside of the embedded block 10. One side of the barb 11 is connected with a spring 19, and one end of the spring 19 is connected with a towing rope 14. The other end of the towing rope 14 is connected to the bottom end of the telescopic sleeve rod 15. The upper part of the telescopic sleeve rod 15 is evenly provided with limiting holes 16, and a limiting block 17 is connected inside the limiting holes 16.

[0031] In this embodiment, during use, the staff first place the embedded block 10 into the road holes pre-drilled on the ground and keep the base 1 flush with the ground. At the same time, drive bolts into the ground to keep the base 1 stable, so as to maintain the stability of the entire road pile. Then, pull the pull ring 28 on the telescopic sleeve rod 15, rotate the telescopic sleeve rod 15 and push it downward. In cooperation with the hinge block 18, the barbs 11 can slide out of the hole 12 and be inserted into the ground soil, making the embedded block 10 more stable and further improving the stability of the entire road pile. When the road construction is completed or the use location needs to be changed, rotate the telescopic sleeve rod 15 so that the limit block 17 is no longer restricted by the limit hole 16. At the same time, manually lift the pull ring 28 upward, and then drive the spring 19 by the traction rope 14 to apply a pulling force to the barbs 11, so as to retract the barbs 11 into the embedded block 10. At the same time, loosen the bolts and replace the road pile to the location where it needs to be installed, improving the practicability of the road pile.

[0032] Embodiment Two
