Composite slurry material for mixing pile foundation reinforcement engineering
The invention discloses a composite slurry material for mixing pile foundation reinforcement engineering. The composite slurry material is prepared from the following components in parts by weight: 150 to 350 parts of cement, 45 to 175 parts of bentonite, 15 to 35 parts of limestone mineral powder, 10.5 to 24.5 parts of superfine slag powder, 0.45 to 2.1 parts of calcium lignosulphonate, 0.45 to 5.25 parts of sodium aluminate, 0.45 to 5.25 parts of water glass, 0.9 to 3.5 parts of sodium carbonate and 132.3 to 584.5 parts of water. The composite slurry is green, environment-friendly, good in economic benefit, simple to prepare and wide in applicable stratum; a conventional stirring pile machine can be adopted for construction, the prepared composite slurry and foundation soil are forcibly stirred to form a cement-soil consolidation body, and the cement-soil consolidation body is high in setting speed, high in early-stage compressive strength, good in anti-seepage effect and high in strong acid resistance and organic matter erosion resistance; the method can be used for soft soil foundation reinforcement engineering, foundation pit waterproof curtain engineering, garbage sanitary landfill anti-seepage engineering and the like.
本发明公开了一种用于搅拌桩地基加固工程的复合型浆材。所述复合型浆材重量份组分包括：水泥150～350份、膨润土45～175份、石灰石矿粉15～35份、矿渣微粉10.5～24.5份、木质素磺酸钙0.45～2.1份、铝酸钠0.45～5.25份、水玻璃0.45～5.25份、纯碱0.9～3.5份、水132.3～584.5份；该复合型浆材绿色环保、经济效益好，制备简单，适用地层广；可采用常规搅拌桩机施工，将制备的复合型浆材与地基土强制搅拌形成水泥土固结体，该水泥土固结体凝结速度快、早期抗压强度高、抗渗效果好、耐强酸性及有机质侵蚀能力强，可用于软土地基加固工程、基坑止水帷幕工程、垃圾卫生填埋场防渗工程等。
