PBA underground excavation station transfer passage structure and construction method thereof
The invention belongs to the technical field of urban rail transit civil engineering, and particularly relates to a PBA underground excavation station transfer passage structure and a construction method thereof. The PBA underground excavation station transfer passage structure comprises a station body and a transfer main passage, at least two small transfer passages are connected between the station body and the transfer main passage, and the width and the height of each small transfer passage are smaller than those of the transfer main passage respectively. The construction method of the PBAunderground excavation station transfer passage structure comprises the steps that S1, the station body is constructed; S2, a deep hole grouting reinforcement area is constructed, and a transfer mainchannel is constructed on the side, away from the station body, of the deep hole grouting reinforcement area; S3, the deep hole grouting reinforcement area is constructed again, and the at least twosmall transfer passages are constructed; and S4, side wall connecting ports of the small transfer passages and the station body are chiseled off. According to the PBA underground excavation station transfer passage structure and the construction method thereof, safe connection with the station body can be guaranteed, and meanwhile congestion at the joint of the transfer passage and the station body is relieved.
本发明属于城市轨道交通土建工程技术领域，具体涉及一种PBA暗挖车站换乘通道结构及其施工方法。一种PBA暗挖车站换乘通道结构，包括车站主体和换乘主通道，车站主体与换乘主通道之间连接有至少两个换乘小通道，换乘小通道的宽度和高度分别小于换乘主通道的宽度和高度。一种PBA暗挖车站换乘通道结构的施工方法，包括：S1：施工车站主体；S2：施工深孔注浆加固区，在深孔注浆加固区远离车站主体的一侧施作换乘主通道；S3：再次施工深孔注浆加固区，施作至少两个换乘小通道；S4：将换乘小通道与车站主体的侧墙连接口凿除。本发明提供了一种能保证与车站主体安全连接，同时缓解换乘通道与车站主体接口处拥堵的PBA暗挖车站换乘通道结构及其施工方法。
