Problems solved by technology

Traditional seismic isolation devices such as seismic isolation supports can only reduce or isolate the horizontal vibration component. Generally speaking, the natural vibration period of towering structures is relatively long. It is generally believed that the pile foundation has good seismic performance, and the pile foundation of the building construction itself has less earthquake damage. For example, in the same site, the additional earthquake settlement of the building with pile foundation is small, and the structural earthquake damage is relatively light.

Embodiment approach

[0030] The specific implementation method is as follows:

[0031] The wedge-shaped pile head 1 is formed by expanding excavation at the head of the new pile foundation, thereby increasing the pile-soil contact area, thereby increasing the vertical bearing capacity and the shear resistance of the pile body. The base damping control device 2 is installed in the inner cavity of the wedge-shaped pile head 1 through connecting bolts 6. The top plate 4, side plate 5 and bottom plate 6 of the damping device 2 are connected by welding to form a base 3. The function of the base 3 is to close the horizontal sliding The mechanism bears the upward pull force, downward force and horizontal force from the horizontal sliding mechanism. A shock absorbing box 7 is arranged on the upper surface of the base plate 6, and the lower part of the shock absorbing box 7 is a fixed plate 9, which is connected and fixed with the base plate 6 by anchor bolts. The upper part of the shock absorbing box 7 t...

Abstract

The invention discloses a multi-dimensional damping control device for a pile foundation. The multi-dimensional damping control device comprises an anti-settling wedge-shaped pile head for increasing the shearing force of the pile foundation, and basic damping control devices arranged in a cylindrical cavity of the wedge-shaped pile head. The wedge-shaped pile head provides work space for the basic damping control devices. Each basic damping control device comprises a cavity defined by a top plate, side plates and a bottom plate, wherein an opening is formed in the top plate, the bottom plate is fixedly connected to the wedge-shaped pile head, a damping box capable of sliding horizontally is arranged in the cavity, a rubber support is arranged on the top of the damping box, the upper end of the rubber support is connected with a bearing plate, and the side plates are provided with spring damping elements connected with the damping box.

Description

technical field [0001] The invention relates to the field of pile foundation damping control, in particular to a pile foundation multi-dimensional damping control device for reducing the vibration response of towering structures. Background technique [0002] With the development of modern society, the construction industry has entered a period of rapid development, and the height and complexity of buildings have continued to increase. Due to the painful cost of casualties in earthquake disasters and the improvement of people's safety awareness, it is of great significance to ensure the safe operation of building structures under the action of earthquakes. Many examples of earthquake damage show that towering structures with poor foundation seismic performance often cause catastrophic consequences when an earthquake occurs. In the majority of cases, sabotage resulted in the collapse of transmission towers. [0003] Traditional anti-seismic methods usually solve seismic pro...
