Embodiment

[0019] The cut-and-cut structure tunnel of this embodiment is composed of at least two integrally cast rectangular structures, wherein the joint 13 between the rectangular structures is located at the estimated ground fissure caused by uneven subsidence or dislocation of the ground place.

[0020] The method adopted in this embodiment is: set a mid-buried waterstop 1 at the structural joint 13, then set the first Ω-shaped waterstop 4 and the second Ω-shaped waterstop 5, and in the middle Embedded grouting pipes 7 are reserved between the buried waterstop 1 and the first Ω-shaped waterstop 4, and between the first Ω-shaped waterstop 4 and the second Ω-shaped waterstop 5 , The pre-embedded grouting pipe 8 can be filled in a limited space by grouting to form a new waterproof line when the mid-buried waterstop or the first OMEGA waterstop fails.

[0021] Cap nut 9, bolt 10, bead 11, pressure plate 12 and back welding angle iron 6 are used for the installation and fixing of Ω type...

Abstract

This invention relates to tunnel. Specific to say it relates to a waterproof method that adapts to large quantity stratum non-homogeneous sedimentation or the disturbed open cut tunnel. This method sets the mid-burying stopping water band and the two-channel OMEGA stopping water band among the configuration distortion slot space. And it obligates grouting tube through the way of joint to make the effect of waterproof. The advantages are: the structure is simple, the quality is credible. It adopts the multiple defending lines as the synthesis waterproof system. When it has certain hydraulic pressure, it has the ability of adapting to larger distortion. This can make an effect of waterproof. It can combine grouting when need, this can attain the aim of sealing the whole big distorted hoop.

Description

technical field [0001] The invention relates to tunnels, in particular to a waterproof method for open-cut tunnels adapted to the uneven settlement or displacement of a large number of strata. Background technique [0002] Ground fissure is a phenomenon that the surface rock and soil layer cracks under the action of natural factors and human factors and forms cracks of a certain length and width on the ground. Ground fissures are the result of superposition of multiple factors. In the active system of ground fissures, the main cause of formation is natural geological processes, supplemented by human factors. The activities of ground fissures have the characteristics of deformation in three-dimensional space, manifested as vertical settlement, horizontal tension and twisting. [0003] Because the activity of ground fissures is a dynamic change process, the causes, mechanisms and types are very complex, and it has obvious segmental activity characteristics according to differ...
