Construction method of mixing pile wall
The invention discloses a construction method of a mixing pile wall. The construction method comprises the following steps that preparation is conducted before construction, specifically, the earth surface in a construction area is treated, and the flatness of a site is ensured; groove construction is conducted, specifically, a groove is excavated, and a mixer is positioned; mixing construction is conducted, specifically, a three-axis mixing pile machine is adopted for construction, pre-mixing sinking is conducted through the three-axis mixing pile machine, and the sinking speed is 0.5-1m/min; after the designed depth is reached, a mortar pump is started, after slurry reaches a slurry spraying opening, the mixing pile machine is lifted, slurry spraying and lifting of the mixing pile machine are achieved simultaneously, and the lifting speed is not larger than 1-2m/min; construction is repeated, the four-spraying and four-mixing process is achieved, and the cement mixing amount reaches 20-25%; and H-shaped steel is inserted, pulled and recycled. Construction of the mixing pile wall is conducted through the method, the stability of adjacent soil can be effectively ensured, and the construction efficiency is improved while the occurrence probability of hazards such as adjacent ground settlement, house inclination, road cracking and underground facility displacement is decreased.
本发明公开了一种搅拌桩墙施工方法，包括如下步骤：施工前准备，对施工区域内地表进行处理，保证场地平整；沟槽建设，进行沟槽开挖，并进行搅拌机定位；搅拌施工，采用三轴搅拌桩机进行施工，通过所述三轴搅拌桩机进行预搅下沉，下沉速度为0.5～1m/min；待到达设计深度后，开启灰浆泵，待浆液到达喷浆口后，提升所述搅拌桩机，实现同时所述搅拌桩机同时喷浆与提升，提升速度不大于1～2m/min；重复施工，实现“四喷四搅”工艺，保证水泥掺入量满足20～25％；H型钢插拔及回收，通过该方法进行搅拌桩墙的施工，可有效的保证邻近土体的稳定性，降低邻近地面沉降、房屋倾斜、道路裂损及地下设施移位等危害发生概率的同时，提高施工效率。
