Foundation pit periodic vibration reduction barrier for rail transit and construction method
The invention discloses a foundation pit periodic vibration reduction barrier for rail transit and a construction method, and belongs to the technical field of vibration reduction barriers. The foundation pit periodic vibration reduction barrier comprises a waterproof curtain, a support pile row, a separation layer, a filling soil layer and a post-pouring concrete layer; the support pile row comprises support piles which are arranged at intervals; each separation layer is arranged between every two adjacent supporting piles, and the separation layers and the supporting piles jointly form a separation structure; the filling soil layer is arranged between the waterproof curtain and the separation structure; the post-pouring concrete layer is arranged between every two adjacent supporting piles and located on the outer side of the separation layer. The foundation pit supporting structure is improved on the basis of an existing foundation pit supporting structure, concrete is filled between the supporting piles, soil is filled between the waterproof curtain and the supporting pile rows, a periodic wave barrier is formed, and environmental vibration caused by public transportation is effectively reduced; the vibration reduction barrier is simple in structure and convenient to construct, the construction cost of the vibration reduction barrier is reduced, the good vibration reduction effect is achieved, and good economic benefits and use value are achieved.
本发明公开了一种用于轨道交通的基坑周期性减振屏障及施工方法，属于减振屏障技术领域，包括止水帷幕、支护桩排、分隔层、填充土层和后浇混凝土层；所述支护桩排包括间隔设置的支护桩；所述分隔层设置在相邻的两支护桩之间，与支护桩共同形成一道分隔结构；所述填充土层设置在止水帷幕和分隔结构之间；所述后浇混凝土层设置在相邻的两支护桩之间，且位于分隔层的外侧。本发明在现有基坑支护结构的基础上进行改进，通过在支护桩之间填充混凝土，在止水帷幕和支护桩排之间填充土体，形成周期性波屏障，有效降低公共交通所引起的环境振动；结构简单，便于施工，降低了减振屏障的施工成本，且实现了较佳的减振效果，具有良好的经济效益和使用价值。
