Deep foundation pit forepoling structure crossing subway line and construction method of deep foundation pit forepoling structure
The deep foundation pit advance support structure crossing the subway line comprises a subway line area (1) and is characterized in that an underground deep foundation pit crossing construction area is arranged over the subway line area (1), and one or more rows of concrete piles (4) are arranged in a left piling area (2) and a right piling area (3) respectively. One or more arc-shaped protection arches (6) which are distributed side by side and cross over the subway line area (1) are erected above the position between the concrete piles (4) located on the left side and the concrete piles (4) located on the right side, and two rows of supporting piles (13) are vertically and fixedly arranged on the arc-shaped protection arches (6) or the cambered surface connecting components (8). Deep foundation pit advance supporting can be carried out on the periphery of the peripheral soil body of a subway line area, stress is uniform, the safety of a subway line is guaranteed to the maximum degree, and the construction efficiency is improved.
一种跨越地铁线路的深基坑超前支护结构及其施工方法，包括地铁线路区域（1），其特征在于：所述地铁线路区域（1）的正上方为地下深基坑跨越施工区域，左打桩区域（2）和右打桩区域（3）内分别设置有一排或多排混凝土桩（4），位于左侧的混凝土桩（4）与位于右侧的混凝土桩（4）之间的上方架设有跨越地铁线路区域（1）的一道或多道并排分布的弧形防护拱（6），弧形防护拱（6）或弧面连接构件（8）上垂直固定设置有两排支护桩（13），本发明结构合理，采用了深基坑超前支护结构，能够地铁线路区域的外围土体周围进行深基坑超前支护，受力均匀，最大程度保证了地铁线路的安全，施工效率得到了提高。
