Multilayer functional gradient vertical shaft wall structure and construction process

Abstract

The invention discloses a multilayer functional gradient vertical shaft wall structure. The shaft wall structure comprises a plurality of coaxial concrete functional layers, wherein the using functions of the functional layers of the whole shaft wall structure are changed in a gradient mode from outside to inside, a functional gradient shaft wall can be composed of an anti-seepage layer, a water pressure resisting layer, an anti-corrosion layer, a fire resisting layer and other functional layers, the water pressure resisting layer is composed of multiple coaxial and equal-thickness structurallayers with the elasticity modulus changed in a gradient mode in the radial direction, the elasticity modulus of the structural layers of the water pressure resisting layer is gradually reduced from outside to inside, the structural layers of the water pressure resisting layer can be in direct contact connection or connected through connecting pieces, and the functional layers are in direct contact connection. The water pressure resisting layer of the functional gradient shaft wall enables stress in the shaft wall to be redistributed by changing the elasticity modulus, the strength of concreteon the outer side of the shaft wall is fully utilized, and the bearing capacity of the shaft wall is fully exerted. The functional layers such as the anti-seepage layer, the water pressure resistinglayer, the anti-corrosion layer and the fire resisting layer of the functional gradient shaft wall are combined for use, the using performance of the shaft wall under the complex geological conditionis improved, and the application range is widened.

Description

technical field [0001] The invention relates to a shaft wall structure, in particular to a multi-layer functional gradient shaft wall structure and construction technology suitable for bearing high ground pressure, high water pressure and complex geological environment in the construction of deep shafts. Background technique [0002] With the depletion of shallow mineral resources mining, domestic and foreign mines are developing in the direction of deep and large-scale mining. From the perspective of domestic resource mining, decades of continuous large-scale resource mining have made shallow mineral resources tend to be exhausted, and mineral resource mining has gradually entered the depth of 1000-2000m. The large-scale development of mineral deposits and the steady implementation of the deep ground strategy have brought about a large number of deep engineering constructions. However, the deep formations have special engineering geological conditions such as high ground st...

Problems solved by technology

However, this type of shaft wall has a complex structure, it is difficult to quickly construct in actual construction, it is difficult to fix the interlayer, the water sealing is poor, and it is difficult to solve the problem of rubber and other materials aging

By changing the elastic modulus, the functionally graded composite well wall makes full use of the material outside the well wall and improves the bearing capacity, but it still cannot cope with the changing and complex geological environment

Simply improving the bearing capacity of the shaft wall structure can no longer fully meet the use requirements of the shaft wall structure
