Description

TECHNICAL FIELD

[0001] The utility model relates to the field of drilling and pouring pile reinforcement cage down technology, especially in a kind of drilling and pouring pile reinforcement cage down auxiliary positioning device. BACKGROUND

[0002] As the key technology of modern foundation engineering, the precision of the reinforcement cage down of drilling and pouring pile directly affects the pile bearing performance.The traditional construction method mainly relies on hoisting equipment and manual adjustment, suspends reinforcement cage by lifting reinforcement and fixes position relying on temporary support structure (such as section steel).In recent years, with the progress of automation technology, part of engineering tries to introduce hydraulic or mechanical auxiliary device to optimize down process, but due to technical limitations, it is still difficult to meet the construction demand of high precision and high efficiency.

[0003] The widely used reinforcement cage down technology has the following significant defects:

[0004] Insufficient positioning accuracy: the length of lifting reinforcement needs to be calculated in advance, but in actual construction, reinforcement cage is easy to swing due to friction of hole wall or external interference, which leads to deviation of perpendicularity, and manual correction is low in efficiency and difficult to adjust in real time.

[0005] Stability defect: traditional section steel support only provides one-way fixation, and reinforcement cage is easy to tilt in deep hole or loose stratum due to uneven stress, even causing cage jamming accident, increasing construction risk.

[0006] Efficiency bottleneck: relying on manual intervention to adjust position, the down process needs to be paused for many times, which prolongs construction period, and the cost loss is significant especially in large-scale engineering.

[0007] Adaptability limitation: existing devices are mostly customized design, which is difficult to adapt to reinforcement cage of different diameters and lengths, and support structure needs to be reconfigured when replacing construction scene, so the flexibility is poor.

[0008] The root of the above problems lies in the lack of dynamic adjustment mechanism and multiple fixation means in existing technology, which makes it difficult to consider precision, efficiency and safety in complex construction environment.
