Sludge soft soil rapid hardening stirring construction method
The invention relates to the technical field of silt soft soil, and discloses a silt soft soil rapid hardening stirring construction method which comprises the following construction steps: 1) stirring in a double-layer stirring structure to prepare a curing agent which is formed by stirring and mixing a main material, an exciting agent and a water body; the main materials comprise fly ash, gypsum, aluminate cement and mineral powder; the exciting agent comprises quick lime, water glass and sodium hydroxide; the mass ratio of the main material to the exciting agent is (9.5-11): (0.8-1.2); the main material and the exciting agent are stirred and mixed to form a mixture, the mixture and the water body are stirred and mixed to form the curing agent, and the mass ratio of the mixture to the water body is (0.9-1.3): (0.8-1.2). (2) a stirring truck is provided, two stirring heads are arranged at the end of a mechanical arm of the stirring truck, and a grouting pipe is arranged in the mechanical arm; in the process that the two stirring heads are inserted into the silt soft soil for stirring, the grouting pipe pours a curing agent into the silt soft soil, the curing agent and the silt soft soil are stirred and mixed, and solidified soil is formed.
本发明涉及淤泥软土的技术领域，公开了淤泥软土快硬搅拌施工方法，包括以下施工步骤：1)、在双层搅拌结构中搅拌制备固化剂，固化剂由主料、激发剂以及水体搅拌混合形成；主料包括粉煤灰、石膏、铝酸盐水泥以及矿粉；激发剂包括生石灰、水玻璃以及氢氧化钠；按照质量占比，主料与激发剂的比例为(9.5～11)∶(0.8～1.2)；将主料以及激发剂搅拌混合，形成混合料，将混合料与水体搅拌混合，形成固化剂，按照质量占比，混合料与水体的比例为(0.9～1.3)∶(0.8～1.2)。2)、提供搅拌车，搅拌车机械臂的端部具有两个搅拌头，机械臂中设有注浆管；将两个搅拌头插入在淤泥软土中进行搅拌的过程中，注浆管往淤泥软土中灌注固化剂，固化剂与淤泥软土搅拌混合，形成固化土。
