Description

Technical Field

[0001] The utility model relates to the technical field of road construction, in particular to a highway roadbed widening positioning device. Background Art

[0002] Roadbed edge piles are wooden stakes that mark the intersection of the roadbed slope line and the ground in each cross section on the ground. The wooden stakes are connected to ensure the line shape of the road. Therefore, in the process of road construction, roadbed edge piles play a very important role. When the highway roadbed is widened, edge piles are needed to locate the line shape of the road.

[0003] Most of the existing roadbed boundary piles have a relatively fixed structure, and most of them cannot be easily disassembled and replaced at the tip of the boundary pile that is inserted into the soil. Since the tip of the boundary pile needs to be inserted into the soil when used for positioning, and when the soil into which the pile is inserted contains relatively hard objects, the tip of the boundary pile is easily caused to be collided and wear and damage occurs. If it is not replaced, the efficiency of the boundary pile being inserted into the soil is easily reduced, and replacing the entire device is likely to increase the replacement cost of the device.

[0004] Therefore, it is necessary to provide a highway roadbed widening positioning device to solve the above technical problems. Utility Model Content

[0019] The utility model has the following beneficial effects:

[0020] 1. Compared with the existing technology, the highway roadbed widening positioning device releases the fixation of the plug block by manually pulling the two fixing rods to stretch the corresponding springs and move one end of the fixing rod out of the fixing groove. The mounting plate, threaded rod 1 and threaded positioning rod can be separated from the pile body at the same time, and the threaded positioning rod can be replaced. This solves the problem of wear and damage to the tip of the side pile caused by collision. If it is not replaced, the efficiency of the side pile insertion into the soil will be easily reduced. If the entire device is replaced, it will easily lead to an increase in the cost of device replacement, thereby improving the practicality of the device.

By manually pulling the two fixing rods 9, the corresponding springs 8 are stretched, and one end of the fixing rod 9 is moved out from the fixing slot 7, the fixation of the plug block 3 is released, and the mounting plate 4, the threaded rod 5 and the threaded positioning rod 6 can be separated from the pile body 1 simultaneously, and the threaded positioning rod 6 can be replaced, which solves the problem of wear and damage caused by collision of the tip of the side pile. If it is not replaced, it is easy to reduce the efficiency of the side pile inserted into the soil, and replacing the entire device is likely to lead to an increase in the cost of replacing the device, thereby improving the practicality of the device.

[0030] The storage component includes a placement groove 11, which is opened at the bottom of the pile body 1. The placement groove 11 is adapted to the fixing plate 10, and the threaded positioning rod 6 is located inside the placement groove 11.
