Asymmetric supporting structure based on prestressed steel reinforced concrete and construction method of asymmetric supporting structure
The invention discloses an asymmetric supporting structure based on prestressed steel reinforced concrete and a construction method thereof.Two layers of supports are arranged on the inner side and the outer side of a fender post adjacent to an existing building structure, and the two layers of supports on each side of the fender post are arranged at intervals in the axial direction of the fender post; the two layers of supports on the outer side of the fender post are arranged between the two layers of supports on the inner side of the fender post, the multiple supporting bodies on the outer side of the fender post and the multiple supporting bodies on the inner side of the fender post are alternately arranged, and the supporting bodies on the inner side and the outer side of the fender post are arranged in the same direction. A plurality of inclined struts are connected between the upper portion of the stress purline of the upper-layer support and the fender post, and a plurality of inclined struts are connected between the lower portion of the stress purline of the lower-layer support and the fender post, so that an asymmetric supporting structure is formed, deformation of the deep foundation pit is well controlled, and safety of surrounding buildings, roads and underground pipeline engineering is protected. The problem that in the construction process of an existing deep foundation pit adjacent to an existing building structure, a maintenance structure is prone to deformation is solved.
本发明公开了一种基于预应力钢骨混凝土非对称支撑结构及其施工方法，在邻近既有建筑结构的围护桩的内外两侧设置两层支撑，围护桩的每一侧的两层支撑沿围护桩的轴向方向间隔设置，围护桩的外侧的两层支撑设置于围护桩的内侧的两层支撑之间，围护桩的外侧的多道支撑本体与围护桩的内侧的多道支撑本体交替设置，围护桩的内外两侧的支撑本体同向设置，上层支撑的受力檩条的上部与围护桩之间连接有多根斜撑，下层支撑的受力檩条的下部与围护桩之间连接有多根斜撑以形成一种非对称支撑结构，进而较好控制深基坑的变形，保护周边建筑物、道路、地下管线工程的安全。本发明解决了现有的邻近既有建筑结构的深基坑施工过程中，维护结构容易变形的问题。
