[0002] Collector line towers usually adopt excavated foundation and manual hole foundation. Although the concrete consumption index of excavated foundation is slightly higher than that of large excavation foundation, its vegetation excavation area is about 20% to 30% of the bottom surface of large excavation foundation. And this type of foundation is the same as the inclined column foundation. The main column outcrop can be adjusted according to the actual terrain, so it can effectively reduce the amount of foundation pit excavation, reduce the damage of construction waste to the natural surface, and protect the natural landscape around the tower base. Although the manual bored pile foundation has high index and high construction technology requirements, considering the geological conditions along the line, it is difficult to ensure the line Consider aspects such as construction quality and reducing vegetation damage, while avoiding secondary treatment caused by violent excavation of foundation pits; since the main reinforcement bars of the excavated foundation are long and heavy, it is impossible to use the conventional method of tying them outside the pit and then lifting them into the pit as a whole, and the only way is to use the stirrup cage wire tying and fixing in the pit; in the process of tying the steel cage, it is difficult to ensure the position, verticality and spacing between the main bars, which affects the molding quality of the steel cage; in the process of concrete pouring, the steel cage is prone to deflection, resulting in the concrete thickness of the steel cage wall not meeting the standard, thus affecting the quality of the tower foundation.
