Description

Technical Field

[0001] The utility model relates to the field of construction of large-diameter bored cast-in-place piles, and particularly includes a steel reinforcement cage positioning and anti-floating integrated device. Background Technique

[0002] The traditional method for installing a steel reinforcement cage generally adopts a direct placement method, without a special fixing structure to fix the steel reinforcement cage in the pile hole. In this way, during the concrete pouring, the steel reinforcement cage is prone to problems such as inclination and floating, resulting in poor vertical bearing capacity of the finally formed concrete pile foundation, thus affecting the reliability of the building. During the process of concrete pouring, due to the buoyancy effect of the concrete on the steel reinforcement cage, the steel reinforcement cage is prone to floating. This will not only affect the vertical bearing capacity of the pile foundation, but also may lead to a decline in the overall quality of the pile foundation.

[0003] Currently, some scholars have proposed construction measures combining fixing parts + supporting parts + elastic connecting parts. In this way, the fixing parts are fixedly connected with the steel reinforcement cage, and through the expanding action of the elastic connecting parts, the steel reinforcement cage is supported on the inner side wall of the pile hole from the outside to the inside to prevent it from inclining and floating. However, such construction methods can only achieve a single anti-floating function. Since there is no positioning and hanging function, the accuracy of the position of the steel reinforcement cage cannot be ensured before the concrete pouring.

[0004] In view of this, aiming at a series of problems existing in the construction process of steel reinforcement cage positioning during the concrete pouring of large-diameter bored cast-in-place piles, it is urgent to invent a simple and effective steel reinforcement cage positioning and anti-floating integrated device, so as to improve the overall quality of the concrete pile foundation and the reliability of the building, and obtain better comprehensive benefits.
