Title: Tao Han and Innovations in Shaft-Wall Construction.

Introduction

Tao Han is an inventor associated with Xuzhou, China. His patent work addresses construction methods for cast-in-place concrete shaft walls, with a focus on improving concrete compactness and water-sealing performance.

Latest Patents

The available information lists 1 patent for Tao Han: “Slipform blade and method for applying pre-compression strain to cast-in-place concrete on well walls.” The invention describes an annular slipform blade foot assembled from connected blade-foot blocks. Each block includes a body, a vertical displacement-generating device, a displacement sensor, and an I-shaped limit plate.

The displacement-generating device moves an arc plate vertically, while the sensor measures movement and the limit plate restricts its maximum distance. By moving the arc plate upward to press against cast-in-place concrete, the method applies pre-compression strain to shaft walls built using a top-down, short-digging and short-laying process. The patent describes this approach as a way to improve the compactness of the shaft-wall concrete and its joints, thereby enhancing the wall’s overall water-sealing performance.

Career Highlights

The patent reflects Tao Han’s contribution to construction technology for shaft walls. Its design combines controlled mechanical displacement, sensing, and movement limits to apply pressure to concrete during construction.
