Ultra-shallow-buried tunnel construction method capable of achieving rapid covering
The invention discloses a rapid covering ultra-shallow-buried tunnel construction method which comprises the following steps: S1, open cutting a foundation trench to a steel cover plate design site at a separation zone, hoisting and laying a prefabricated steel cover plate into the foundation trench, and laying a pavement layer above the steel cover plate; s2, open-digging a foundation trench at a roadway on one side of the separation strip to a design site of a steel cover plate, hoisting the prefabricated steel cover plate, paving the prefabricated steel cover plate into the foundation trench, and paving a pavement layer above the prefabricated steel cover plate; s3, open excavation of a foundation trench is carried out on a roadway on the other side of the separation strip to a steel cover plate design site, the prefabricated steel cover plate is hoisted and laid in the foundation trench, and a pavement layer is laid on the steel cover plate; and S4, an advance support is constructed, and the tunnel is subsurface excavated step by step under the steel cover plate and the advance support. The method does not need extra foundation construction, does not need temporary large line change on the current road, is short in construction operation time, and is especially suitable for a construction environment in which land is insufficient and traffic is only allowed to be locally interrupted for several hours.
本发明公开了一种快速上盖的超浅埋隧道施工方法，包括以下步骤：S1.在分隔带处明挖基槽至钢盖板设计位点，将预制的钢盖板吊装、铺设至基槽内，并在钢盖板上方铺设路面层；S2.在分隔带一侧车行道处明挖基槽至钢盖板设计位点，将预制的钢盖板吊装、铺设至基槽内，并在钢盖板上方铺设路面层；S3.在分隔带另一侧车行道处明挖基槽至钢盖板设计位点，将预制的钢盖板吊装、铺设至基槽内，并在钢盖板上方铺设路面层；S4.施作超前支护，并在钢盖板与超前支护下分步暗挖隧道。本发明不需要进行额外的基础施工，且无需对现状道路进行临时大改线，施工作业时间短，尤其适用于用地紧张、仅允许交通局部中断几小时的施工环境。
