Tunnel roadbed frost boiling disease treatment method
The invention discloses a tunnel roadbed frost boiling disease treatment method. The method specifically comprises the following steps: 1) determining a frost boiling mud emitting position; 2) arranging drill holes; 3) performing deep grouting; and 4) performing interlayer grouting. Compared with the prior art, the method has the advantages that the steps are clear, implementation is convenient, the used materials have high fluidity and permeability, segregation and bleeding are avoided, self-flowing compaction forming can be achieved, the overall compressive strength can reach 60 MPa or above after grouting permeates into concrete cracks, and the impact toughness can reach three times or above that of common high-strength concrete. The paint has excellent freezing resistance and aging resistance, is corrosion-resistant and rust-proof, and does not shrink in the hardening process. Good popularization prospects and market values are realized.
本发明公开了一种隧道路基翻浆病害整治方法，具体包括以下步骤：1)确定翻浆冒泥位置；2)钻孔布置；3)深层注浆；4)层间注浆。本发明与现有技术相比的优点在于：步骤清晰，实施方便，使用材料具有高流动性和渗透性，无离析泌水，可自流密实成型，灌浆渗入砼裂隙后整体抗压强度可达60MPa以上，冲击韧性可达普通高强砼的3倍以上。抗冻性、耐老化性优异，防腐防锈，且硬化过程无收缩。具有很好的推广前景和市场价值。
