Construction method for shallow-buried and subsurface-excavated tunnel foundation pit under protection of cover plate
The invention provides a construction method for a shallow-buried and subsurface-excavated tunnel foundation pit under protection of a cover plate, and belongs to the technical field of tunnel construction. The construction method comprises the following steps that 1, construction preparation is conducted; 2, municipal pipelines are moved back, and backfilling and earthing are conducted; 3 to 11, a first soil body area, a second soil body area, a third soil body area, a fourth soil body area, a fifth soil body area, a sixth soil body area, a seventh soil body area, an eighth soil body area, a ninth soil body area and a ninth soil body area are sequentially constructed; 12, a tunnel bottom plate is poured; 13, tunnel side walls and middle walls are poured; 14, a tunnel top plate is poured; and 15, construction backfilling is conducted in the space between the reinforced concrete cover plate and the tunnel top plate. According to the construction method, advanced protection is conducted through underground diaphragm walls, steel lattice columns, stand column piles and the reinforced concrete cover plate, then construction modes such as advanced grouting small guide pipes are adopted in working wells at the two ends, tunnel construction can be conducted in the construction environment that a deep foundation pit project is adjacent to surrounding buildings or foundation pits are laid along the edges, and the influence on road traffic of a construction area is reduced.
一种盖板防护下的浅埋暗挖隧道基坑施工工法，属于隧道施工技术领域。它包括以下步骤：步骤一：施工准备；步骤二：回迁市政管线，回填覆土；步骤三至第步骤十一：依次施工第一土体区域至第九土体区域；步骤十二：浇筑隧道底板；步骤十三：浇筑隧道侧墙及中墙；步骤十四：浇筑隧道顶板；步骤十五：在钢筋混凝土盖板与隧道顶板之间的空间内施工回填。本发明采用地下连续墙、钢格构柱、立柱桩以及钢筋混凝土盖板超前防护，然后从两端工作井中采用超前注浆小导管等施工方式，能够在深基坑工程紧邻周边建构筑物或者贴边布设基坑的施工环境下，进行隧道施工，且减少了对施工区域的道路交通影响。
