Liquefiable site reinforcing method based on high-strength deep mixing piles
The invention discloses a liquefiable site reinforcing method based on high-strength deep mixing piles, which comprises the following steps: step 1, detecting a site on site so as to determine the relative density of each soil layer; 2, determining the required slag powder content according to different relative densities and the target compressive strength value of the cement; step 3, determining the content of water glass and NaOH according to the content of the slag powder; and 4, slag powder is injected into the saturated sandy soil through high pressure, then water glass and NaOH are mixed and injected into the pile body, and reinforcement is completed. The invention provides a novel mixing pile for replacing a cement mixing pile, the novel mixing pile is prepared from slag powder, sand, water glass, sodium hydroxide and water according to a certain proportion, the preparation process is simple and convenient, and the strength of a building material is improved while the influence of cement production on the environment is reduced.
本发明公开了一种基于高强度深层搅拌桩的可液化场地加固方法，包括以下步骤：步骤1，对现场的场地进行探测，从而确定各土层的相对密度；步骤2，根据不同的相对密度以及水泥的目标抗压强度值，确定所需要的矿渣粉含量；步骤3，通过矿渣粉含量确定水玻璃和NaOH的含量；步骤4，先将将矿渣粉通过高压注入到饱和砂土中，再将水玻璃和NaOH混合注入到桩体上，即完成加固。本发明提供了一种替代水泥搅拌桩的新型搅拌桩，该新型搅拌桩是由矿渣粉、砂、水玻璃、氢氧化钠和水按一定比例制作而成，制作工艺简便，在减少水泥生产带给环境影响的同时，提高了建筑材料的强度。
