    摘要： The present invention provides for a compressible grout mix for filling an annular gap between a tunnel rock wall surface and a tunnel liner of a tunnel in a rock formation subject to time dependent deformation after excavation and a method of filling the annular gap between a tunnel rock wall surface and a tunnel liner of a tunnel in a rock formation subject to time dependent deformation after excavation utilizing the compressible grout mix for resilient absorption of forces in the hardened state of the compressible grout mix exerted by the time dependent deformation of the rock wall surface into the tunnel opening. The method includes:a. providing the compressible grout mix comprising hydraulic binding agent, bentonite clay, polymer foam particles, water-reducing admixture, water and air,b. placing the compressible grout mix in the annular gap between the tunnel wall rock surface and the tunnel liner, andc. allowing the compressible grout mix to set, wherein the compressible grout mix in the hardened state has a compressible ratio greater than the anticipated time dependent deformation.

    摘要： A compression body is inserted into the contraction joint between two tunnel lining elements, which body deforms in response to a compressive load caused by the tunnel lining elements moving towards each other. The compression body is composed of a material containing voids, and has a compressive strength of at least 1 MPa and a void fraction of between 10% and 90% of its total volume. The compression body may be composed, for example, of steel foam, or of a mixture which contains cement and blown-glass particles or plastic particles.When a predetermined compressive load is exceeded, the voids within the compression body collapse in a stepwise manner, or are compressed in a stepwise manner.

    摘要： A lining for a tunnel, shaft or the like comprising a series of rings joined in end-to-end relation wherein each ring comprises a plurality of segmental blocks connected together in side-by-side relation by at least one resiliently deformable fishplate which is secured to the blocks and wherein each ring is connected to an adjacent ring by bolts, each bolt passing through at least a portion of one block of each of two adjacent rings and serving to compress the or each fishplate located between said rings. Each block is made from a shell made of substantially water-proof, chemically inert material and comprising a base having a pair of side walls and a pair of end walls defining a mold cavity for receiving structural material, each side wall having an inwardly directed recess extending substantially the length of the side wall and each end wall having a groove adapted to receive part of a fishplate to secure the shell to another shell in side-by-side relation.
