Description

TECHNICAL FIELD

[0001] The utility model relates to the field of building construction, especially a pouring pile reinforcement cage concrete pouring height control device. BACKGROUND

[0002] The rotary drilling cast-in-place pile has great bearing capacity, and is therefore widely used in pile foundations of building engineering. Before the rotary drilling cast-in-place pile is filled with concrete, the pile reinforcement cage needs to be lowered into the rotary drilling hole. The pile reinforcement cage and the concrete pouring are integrated as a pile foundation. The pile top elevation refers to the elevation of the top of the cast-in-place pile, which has an important influence on the quality and stability of the entire project. During the construction process, the pile hole has no additional light and is in a pitch-black state, so the pouring height of the concrete cannot be observed. In order to ensure the accuracy of the pile top elevation, a flashlight is usually used to observe the height during pouring. In the actual operation process, the pouring height may be seriously higher than the elevation due to the failure to observe the height, which delays the construction progress and wastes a large amount of concrete, causing economic losses. Therefore, improvement is needed. SUMMARY
