The ground mark is suitable for marking the name, the trend and the flow direction of the pipeline, and the requirements of normal use, maintenance, safety and the like of the pipeline cannot be influenced by the permanent ground.
The strategic location of the ground pointing of conventional cables is accomplished by a diamond shaped signboard, which presents only one direction. To the position that the key position ground trend of cable was changed, especially in positions such as road and river gush, there is the unclear condition of sign, leads to fortune dimension personnel can't discern cable route fast and the relatively poor problem of suitability, greatly reduced the efficiency of cable fortune dimension, there is the lower problem of cable fortune dimension efficiency promptly.
In addition, when the traditional cable pointing identification pile is installed, the traditional cable pointing identification pile is only inserted into the ground for fixing, the fixing between the traditional cable pointing identification pile and the ground is not firm enough, the traditional cable pointing identification pile is fixed and loosened through certain shaking, and the traditional cable pointing identification pile can be pulled away. Affecting its normal use.
