Segmented hot-melt pile end support stiffness adjusting device

Abstract

The invention discloses a segmented hot-melt pile end support stiffness adjusting device. The device comprises a raft plate and a pile body fixedly arranged on a pile foundation, wherein a ground beamis poured at the bottom of the raft plate, a mounting groove is reserved in the bottom of the ground beam, the inner portion of the mounting groove is fixedly provided with a cylinder body, the end of the upper end of the pile body is fixedly provided with a top plate, and a segmented hot-melt telescopic element is arranged between the upper portion of the top plate and the inner top wall of thecylinder body. The segmented hot-melt pile end support stiffness adjusting device has the advantages that running is stable, safe and reliable, the disadvantage that the bearing stiffness of an existing pile end stiffness adjusting device cannot be actively interfered or adjusted according to needs after the existing pile end stiffness adjusting device is arranged, the bearing stiffness of the pile foundation can be interfered and adjusted 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 and convenient, the adjustment precision is high, the degree of quantification is high, and the device has a significant promotion effect on the development and application of the whole process active control theory of the pile-raft foundation.

Description

technical field [0001] The invention relates to the technical field of pile raft foundation construction, and more specifically relates to a segmental heat-melted pile end support stiffness adjustment 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 p...

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a segmental heat-melted pile end support stiffness adjustment device, which operates stably, is safe and reliable, and effectively utilizes the fusible characteristics of low melting point metals to reduce the existing pile end stiffness. The adjustment device is further improved to overcome the drawback that the existing pile end stiffness adjustment device cannot actively intervene and adjust the support stiffness according to the needs, and can intervene and adjust the pile foundation support stiffness according to the needs during the whole process of building construction and use. The adjustment, 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. Good anti-corrosion, high temperature resistance, insulation, anti-aging performance, especially important is to prevent the phenomenon of short circuit in the working process of the device
