Title:
MULTI-LAYER FUNCTIONAL GRADIENT VERTICAL SHAFT WALL STRUCTURE AND CONSTRUCTION PROCESS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/032862
Kind Code:
A1
Abstract:
Disclosed is a multi-layer functional gradient vertical shaft wall structure. The shaft wall structure comprises a plurality of coaxial functional layers of concrete; the use functions of the functional layers of the whole shaft wall structure vary gradually from outside to inside; a functional gradient shaft wall may be composed of functional layers, such as an impervious layer, a water-pressure-resistant layer, a corrosion-resistant layer (7), and a fire-resistant layer (1); the water-pressure-resistant layer is composed of a plurality of coaxial structural layers with equal thicknesses, the elastic moduli of same varying in a gradient manner in a radial direction, wherein the elastic moduli of the structural layers of the water-pressure-resistant layer are gradually reduced from outside to inside, and the structural layers of the water-pressure-resistant layer can be in direct contact connection or connected by means of connecting members; and the functional layers are in direct contact connection. The water-pressure-resistant layer of the functional gradient shaft wall has varied elastic moduli to redistribute internal stress in the shaft wall, fully utilizes the strength of concrete on the outer side of the shaft wall, and fully utilizes the bearing capacity of the shaft wall. The functional layers, such as the impervious layer, the water-pressure-resistant layer, the corrosion-resistant layer (7) and the fire-resistant layer (1), of the functional gradient shaft wall are used in combination, such that the performance of the shaft wall used under complex geological conditions is improved, and the application range is widened.
