High-speed rail station building canopy column pile foundation underpinning pouring module and construction technology thereof
The invention relates to the technical field of existing high-speed rail platform current situation pile foundation protection, in particular to a high-speed rail station building canopy column pile foundation underpinning pouring module and a construction technology thereof. The high-speed rail station building canopy column pile foundation underpinning pouring module comprises a supporting table, wherein the upper end of the supporting table is fixedly sleeved with a pouring module, embedded steel bars are transversely poured in the supporting table, three sets of drill holes distributed in a circumferential array mode are excavated in the lower end of the pouring module, connecting cross beams connected with embedded steel bars are transversely arranged in an inner cavity of the pouring module, a pouring opening is formed in the upper end of the pouring module, a steel bar frame is vertically connected to the connecting cross beams in an inserted mode, and the inner cavity of the pouring module and inner cavities of the drill holes are integrally poured through concrete. The pouring module has the beneficial effects that the supporting strength of stand columns is improved by arranging expansion tables and partial pressure pipe piles, disturbance generated in the construction process of a square deep foundation pit in front of a high-speed rail platform is avoided, the structural stability of a high-speed rail station building in the construction period of the square deep foundation pit in front of the high-speed rail platform can be guaranteed, the safety of existing structures close to the high-speed rail is guaranteed, meanwhile, the construction efficiency is improved, and the safety cost can be effectively reduced.
本发明涉及既有高铁站台现状桩基保护技术领域，具体为一种高铁站房雨棚柱桩基托换浇筑模块及其施工工艺，包括支撑台，支撑台的上端固定套接有浇筑模块，支撑台中横向浇筑有预埋钢筋，浇筑模块的下端挖掘有圆周阵列分布的三组钻孔，浇筑模块的内腔中横向设置有连接预埋钢筋的连接横梁，浇筑模块的上端设置有浇筑口，连接横梁上竖直插接有钢筋架，浇筑模块的内腔与钻孔的内腔均通过混凝土一体浇筑，有益效果为：通过设置扩展台和分压管桩提高了对立柱的支撑强度，避免了高铁站台站前广场深基坑施工过程中产生的扰动，能保证站前深基坑施工期间高铁站房结构稳定性，保证了临近高铁等既有结构的安全性，同时提高了施工效率，可有效降低安全成本。
