A thermal fusion effect pile end stiffness adjustment device

Abstract

The invention discloses a thermal fusion effect pile end rigidity adjustment device, which comprises a raft and a pile body fixedly installed on the pile foundation. The bottom of the raft is poured with a ground beam, and the bottom of the ground beam is reserved with an installation groove. A cylinder body is fixedly installed inside the cylinder body, and a hot-melt telescopic element is arranged between the upper part of the top plate and the inner top wall of the cylinder body. The present invention is stable in operation, safe and reliable, and further improves the existing pile end stiffness adjustment device by effectively utilizing the thermal fusion effect to overcome the fact that the supporting stiffness cannot be actively intervened and adjusted according to needs after the existing pile end stiffness adjustment device is installed It can intervene and adjust the supporting stiffness of the pile foundation according to the needs in the whole process of building construction and use, the control and adjustment are more flexible and convenient, the implementation is more reliable, the construction operation is simple, the adjustment accuracy is high, and the degree of quantification is high. The development and application of the active control theory for the whole process of raft foundation has a significant promotion effect.

Description

technical field [0001] The invention relates to the technical field of pile raft foundation construction, in particular to a thermal fusion effect pile end stiffness adjusting device. Background technique [0002] With the rapid development of high-rise buildings, the foundation forms that determine the overall stability and safety of high-rise buildings have become larger and more complex, and higher requirements have been put forward for piled raft foundations as the main foundation form. The piled raft foundation of high-rise buildings plays an important role in project construction, and it accounts for an increasing proportion of the total project cost and total construction period. The safety and effectiveness of high-rise building piled raft foundations in the early design, optimization, later construction, and use become increasingly prominent and attract the attention of all parties. The main objects of early design and optimization of the piled raft foundation of h...

Problems solved by technology

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a thermal fusion effect pile tip stiffness adjustment device, which is stable in operation, safe and reliable, and can further improve the existing pile tip stiffness adjustment device by effectively utilizing the thermal fusion effect. In order to overcome the shortcomings of the existing pile end stiffness adjustment device, the support stiffness cannot be actively intervened and adjusted according to needs, and the pile foundation support stiffness can be intervened and adjusted as needed during the entire process of building construction and use, and the control and adjustment are more efficient. It is flexible and convenient, more reliable in implementation, easy in construction operation, high in adjustment accuracy and high in quantification, and has a significant effect on promoting the development and application of active control theory in the whole process of piled raft foundation. High temperature, insulation, anti-aging performance, and most importantly, it can prevent the short circuit of the device during the working process
