[0002] In the field of construction engineering, pile foundation is the basic structure that bears the weight of the building. Its stability and safety are directly related to the safety and durability of the entire building. With the continuous development of construction technology, the construction method and fixing technology of pile foundation are also constantly improving.

These methods can meet the basic stability requirements of pile foundations to a certain extent. However, in practical applications, these methods have also exposed some problems. First, traditional fixing methods often lack flexibility, and it is difficult to accurately adjust the spatial angle and position before the pile pipe is fixed, resulting in low construction efficiency and difficulty in ensuring the precise positioning of the pile foundation. Secondly, after the pile foundation is solidified, due to the lack of effective monitoring methods, it is difficult to detect the settlement, displacement and slope changes of the pile foundation in time, which increases the safety risk of the building.

[0005] The above-mentioned device is connected to the connecting plate through a connecting rod, and can stably fix multiple support frames, thereby achieving the effect of jointly fixing the pile foundation, which significantly increases the fixing effect. However, when the pile pipe of the pile foundation is fixed by the above-mentioned technical method, on the one hand, it is not convenient to realize the flexible adjustment of the spatial angle and spatial position before the pile pipe is fixed, and on the other hand, it is not convenient to realize the detection of the settlement, displacement and slope change of the pile pipe body after the pile pipe is solidified.

[0033] When in use, the rotation axis of the rotating frame 5 is in the same straight line as the axis of the pile pipe body 2, and the axis of the guide arc groove 4 is on the rotation axis of the rotating frame 5; When the pile pipe body 2 is fixed, when the layout angle and the fixed angle of the pile pipe body 2 need to be adjusted, the worm motor c can drive the rotating frame 5 to rotate at a set angle, thereby changing the fixed angle of the pile pipe body 2; A clamping member is installed on the rotating frame 5, and two mirror-image fixed components are transmission-connected to the clamping member.
