Embodiment Construction

[0060] The following is attached Figure 1 to Figure 4 The specific implementation manner of the present invention will be described in further detail.

[0061] A kind of ELF railway tunnel water leakage disease control method:

[0062] 1. Technical implementation plan

[0063] Considering the causes of water leakage in railway tunnels, new organic chemical grouting materials and new inorganic plugging materials are used in combination; a new concept of plugging and reinforcement is combined; materials are selected according to point, line, and surface leakage classification; construction adopts plugging, prevention, Combination of drainage and drainage; focus on the research and promotion of the principles of grouting at surrounding points, combining elasticity and softness, multi-channel fortification, and comprehensive improvement; aiming at various forms of leakage water in railway tunnels, to achieve correct material selection, scientific plugging, and one-time Construc...

Abstract

The invention relates to an ELF railway tunnel water leakage, block dropping and grout turning disease treatment method. A non-curing waterproof material is creatively applied to railway tunnel waterleakage and grout turning diseases, and the problem of water leakage of a railway tunnel under the condition of high-frequency vibration disturbance is solved by utilizing the advantages of a materialwith extremely high flexibility, self-healing property and bonding property and strong adaptability to deformation and cracking of a base layer; a modified moisture-resistant and low-viscosity epoxygrouting material is used in construction joints and irregular cracks, so that the advantages that the material can reinforce a structure while grouting and leaking stoppage are exerted; an improved acrylate grouting material is used for treating water leakage of fine cracks such as irregular cracks, expansion joints and settlement joints of a concrete structure, the characteristics that the seepage force is very high, the grout can be ensured to penetrate into the gaps, the elongation rate is high, the deformation resistance is high, the temperature adaptability is wide and the like are utilized, the solidification speed of the grout is adjusted according to different water leakage conditions, the water stopping and blocking requirements are met, and the repeated waste of materials is reduced.

Description

technical field [0001] The device relates to the technical field of railway tunnel disease control, in particular to a method for treating water leakage, block falling and slurry muddy in ELF railway tunnels. Background technique [0002] The water leakage disease of railway tunnel seriously affects the safety of railway transportation and restricts the rapid development of railway transportation. In order to control various diseases, the railway department spends a lot of manpower, material resources and financial resources every year, but my country is still in a relatively backward position in the analysis of disease control. At present, after the appearance of tunnel diseases, it can only be combined with the apparent characteristics of tunnel diseases and The geology, climate, hydrology and other information of the area where the tunnel is located, judge the cause of the disease based on experience, and formulate corresponding reinforcement plans and measures. There is ...
