Construction method for double-row support piles and waterproof curtain in narrow space
The invention discloses a construction method for double-row support piles and a waterproof curtain in a narrow space, which comprises the following steps: 1, surveying a construction area (7) of the double-row support piles and the waterproof curtain (1), and determining an obstacle (3); 2, drilling and obstacle removing are carried out to form a guide groove, so that the double-row support piles and the waterproof curtain can be effectively implemented along the guide groove; 3, the three-axis cement mixing pile equipment drills downwards along the guide groove, and a waterproof curtain is constructed; 4, the double-row supporting piles comprise outer-row supporting piles (21) adjacent to the existing building (5) and inner-row supporting piles (22) located between the waterproof curtain and the newly-built building (6); constructing the outer-row support piles by the rotary excavating drill; 5, inner-row support piles are constructed; and 6, a foundation pit of the newly-built structure is excavated, and deformation of the double-row supporting piles and the existing structure is monitored in time in the excavation process. The construction process is optimized, and the adjacent existing building is effectively protected when the double-row support piles and the waterproof curtain are constructed.
本发明公开了一种狭窄空间内双排支护桩及止水帷幕的施工方法，包括步骤：1、勘察双排支护桩及止水帷幕(1)的施工区域(7)，确定障碍物(3)；步骤2：钻孔清障形成导槽，使双排支护桩及止水帷幕能沿导槽有效实施；步骤3：三轴水泥土搅拌桩设备沿导槽下钻，止水帷幕施工；步骤4：双排支护桩包括紧邻既有构筑物(5)的外排支护桩(21)和位于止水帷幕与新建构筑物(6)间的内排支护桩(22)；旋挖钻施工外排支护桩；步骤5：施工内排支护桩；步骤6：新建构筑物基坑开挖，开挖过程中及时对双排支护桩及既有构筑物的变形进行监测。本发明优化了施工工序，在施工双排支护桩及止水帷幕时对紧邻既有构筑物提供有效的保护。
