High-pressure combined washing grouting method and structure in karst region
The invention discloses a high-pressure combined washing grouting method and structure in a karst region. When a filling-type karst cave or a grike exists in the grouting process, high-pressure water or wind flushes filler out, then cement mortar or cement paste of 0.5:1 is refilled, and a common cement grouting method is adopted for grouting 24-72 hours later after condensation. The high-pressure combined washing grouting method is an economical and efficient grouting processing technology specific to karst caves, grikes and the other geological flaw sections, and has the advantages of being simple (not needing special construction equipment and operators), obvious in washing effect, capable of largely improving construction efficiency and guaranteeing grouting quality, and the like. When the high-pressure combined washing grouting method and structure are used for grouting washing and grouting in the karst caves, grikes and the other geological flaw sections in the karst region, the design requirements can be met effectively and rapidly, the construction efficiency can be largely improved, and waste of grouting raw materials is reduced.
