Construction process of shallow-buried excavation tunnel near underneath passing municipal drainage pipe
The invention relates to the technical field of tunnel construction, and provides a construction process for a shallow-buried excavation tunnel close to an underneath passing municipal drainage pipe, which comprises the following steps: S1, dividing a drainage pipe area above a tunnel construction area into drainage pipe construction sections; s2, closure forced drainage construction of a drainage pipe construction section; s3, an open cut foundation pit is constructed on one side of the drainage pipe construction section; s4, holes are drilled in the side wall, facing one side of the drainage pipe construction section, of the open-cut foundation pit at equal intervals in the extending direction of the drainage pipe construction section, and concrete grout is injected to form a bottom supporting piece; s5, holes are obliquely and inwards led to the bottom of the bottom supporting piece at equal intervals on the two sides of the drainage pipe construction section on the ground in the extension direction of the drainage pipe construction section, and concrete grout is injected into the holes through grouting floral pipes to form side supporting pieces; s6, the drainage pipe construction section is cleaned and repaired; s7, a tunnel top pipe shed is constructed; and S8, tunnel excavation construction is conducted. The drainage pipe has the effect of reducing the influence of tunnel construction on the drainage pipe.
本申请涉及隧道施工的技术领域，提出了一种浅埋暗挖隧道临近下穿市政排水管的施工工艺，包括以下步骤：S1：将位于隧道施工区上方的排水管区域划分为排水管施工段；S2：排水管施工段截流强排施工；S3：在排水管施工段的一侧施作明挖基坑；S4：从明挖基坑朝向排水管施工段一侧的侧壁沿排水管施工段的延伸方向等间距钻孔并注射混凝土浆液以形成底托件；S5：在地面于排水管施工段两侧沿排水管施工段延伸方向等间距斜向内引孔至底托件底部，并通过注浆花管往孔洞内注入混凝土浆液形成侧托件；S6：排水管施工段清理与修复；S7：施作隧道顶部管棚；S8：隧道开挖施工。本申请具有减少隧道施工对排水管的影响的效果。
