Municipal road deep foundation pit supporting construction technology
The invention relates to the field of municipal road processes, and provides a municipal road deep foundation pit supporting construction technology which comprises the steps that S1, construction areas are delimited, the construction areas are divided into two first areas and a second area, and the two first areas are located on the two sides of a municipal road respectively; s2, first precast piles are implanted into the two sides of the municipal road to form a foundation pit supporting body; s3, earthwork located in the area defined by the corresponding precast piles in the first area is removed; s4, horizontal drilling is conducted on the earthwork located in the second area to form a drilling channel; s5, the second precast pile is implanted into the drilling channel; step S6, repeating the steps S4 to S5 to form a tunnel support main body with an arc-shaped cross section; and S7, earthwork, located below the tunnel supporting body, of the second area is removed. On the basis, in the construction process of the deep foundation pit of the municipal road, the municipal road does not need to be subjected to closed management.
本申请涉及市政道路过程的领域，提供了一种市政道路深基坑支护施工工艺，包括步骤S1、划定施工区域，将施工区域分别第一区域和第二区域，所述第一区域设置有两道且分别位于市政道路的两侧上；步骤S2、在市政道路的两侧均植入第一预制桩以形成基坑支护主体；步骤S3、清除第一区域内位于相应预制桩围合区域内的土方；步骤S4、对位于第二区域内的土方进行水平钻孔以形成钻孔通道；步骤S5、将第二预制桩植入钻孔通道内；步骤S6、重复S4‑S5，以形成横截面呈弧形状的隧道支护主体；步骤S7、将第二区域位于隧道支护主体下方的土方清除。基于此，本申请在实施在市政道路的深基坑施工过程中，市政道路无需做封闭管理的效果。
