Embodiment Construction

[0016] In order to facilitate those skilled in the art to understand and implement the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings. It should be understood that the implementation examples described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0017] like figure 1 and figure 2 As shown, the present invention provides a built-in viscous damping geotextile, the outer layer of the geotextile is a woven geotextile, and the inside is a vertical PVC hose 3 and a horizontal PVC hose 2 that are criss-crossed inside, and the PVC hose is filled with viscous damping. The woven geotextile is woven by warp and weft. The warp and weft are composite yarns interwoven with polypropylene woven silk and carbon fiber. The hysteretic damper is epoxy.

Abstract

The invention discloses an internal viscous damper geotechnical cloth and a method for structure reinforcement by the cloth. An outer layer of the internal viscous damper geotechnical cloth is a woven geotechnical cloth, and crisscrossed PVC (polyvinyl chloride) hoses are arranged inside the internal viscous damping geotechnical cloth and filled with viscous dampers. The internal viscous damper geotechnical cloth is arranged between a steel tube and concrete, clings to the inner wall of the steel tube, is connected with the inner wall of the steel tube through structural adhesives and wraps the whole length of the steel tube concrete. The seismic resistance of the steel tube concrete is improved by the aid of excellent energy dissipation capability of the viscous dampers and high tensile strength of the woven geotechnical cloth, epoxy resin in the PVC hoses flows out and can serve as an adhesive for adhering cracks of a steel tube concrete column, so that the structure has a certain self-healing property, and the strength of the structure is greatly enhanced. Besides, the geotechnical cloth can prevent the steel tube and the concrete from stripping.

Description

technical field [0001] The invention belongs to the technical field of building structures, and in particular relates to a built-in viscous damping geotextile with earthquake resistance and self-healing properties and a method for structural reinforcement using the geotextile. Background technique [0002] Energy dissipation and shock absorption technology is to design some components in the structure as energy dissipation components, or to set energy dissipation components in certain parts of the structure. At present, the more effective way of energy dissipation and shock absorption is to install viscous dampers. Viscous dampers are widely used in the field of civil engineering as an energy-dissipating and shock-absorbing device that does not require external energy input. However, since it is usually installed outside the structure, it is inevitably affected by temperature changes, chemical corrosion, etc., which greatly reduces the service life. Good guard node.
