Treatment method of soft soil foundation municipal road
The invention relates to the field of road construction, and particularly discloses a treatment method of a soft soil foundation municipal road. The treatment method of the soft soil foundation municipal road comprises the steps that 1, pile positions are set, specifically, a plurality of grouting points are selected at intervals of 10-20 m; 2, stirring, guniting and sinking are conducted, specifically, the mixed slurry is injected into the pile position at the pressure of 0.15-0.25 kPa and the speed of 40-50 cm/min, the sinking depth is 2.5-5.0 m, and stirring is conducted for 25-40 s; 3, stirring and lifting are performed, wherein lifting a pile position at a speed of 90-110 cm/min, wherein the pile position is 25-35 cm higher than the pile position; 4, secondary guniting sinking and stirring lifting are conducted, specifically, the step 2 and the step 3 are repeatedly executed in sequence; and 5, completing inspection is performed, wherein the slurry in the step 2 comprises the following components in parts by weight: 290-320 parts of water, 310-340 parts of cement, 4-7 parts of water glass, 9-15 parts of carbonyl pyroaldehyde, and 5-8 parts of carbamide. The method has the advantage that the splitting tensile strength of the soft soil foundation is greatly improved while the compressive strength of the soft soil foundation is kept.
本申请涉及道路建设领域，具体公开了一种软土地基市政道路的处理方法。软土地基市政道路的处理方法包括：步骤1，设置桩位：以10‑20m为间隔，选取若干注浆点；步骤2，搅拌喷浆下沉：取浆料以0.15‑0.25kPa的压力，速度40‑50cm/min向桩位内注射混合浆料，下沉深度2.5‑5.0m，搅拌25‑40s；步骤3，搅拌提升：以90‑110cm/min提升出桩位，提升高于桩位25‑35cm；步骤4，二次喷浆下沉、搅拌提升：按顺序重复步骤2和步骤3；步骤5，完工检查。步骤2中的浆料包括：水290‑320份；水泥310‑340份；水玻璃4‑7份；羰基焦醛9‑15份；碳酰二胺5‑8份。本申请具有保持软土地基的抗压强度的同时大幅提高软土地基的劈裂抗拉强度的优点。
