Subway station accessory and main body connecting section ground wall door opening structure and construction technology thereof
The invention discloses a subway station accessory and main body connecting section ground wall door opening structure and a construction technology thereof. The subway station accessory and main body connecting section ground wall door opening structure comprises a station main body structure and a station accessory structure, a main body structure top plate and an accessory structure top plate are correspondingly arranged at the upper ends of the station main body structure and the station accessory structure, a main body structure middle plate and an accessory structure bottom plate are correspondingly arranged at the lower ends of the station main body structure and the station accessory structure, a coping beam, an underground diaphragm wall, a top beam and a concrete support are arranged at the upper end of the main body structure top plate, and a temporary road is arranged above the concrete support. The construction technology comprises the steps that a main body foundation pit first-channel concrete support in a connecting section range and the top beam are reserved; the coping beam is additionally arranged; an auxiliary foundation pit is excavated; an accessory structure bottom plate is constructed, and a downward concave force transmission plate strip is additionally constructed; side walls and top plates of accessory structures are constructed; a connecting section ground wall door opening is integrally dug; and a connecting section post-cast section is constructed. The subway station accessory and main body connecting section ground wall door opening structure and the construction technology thereof have the beneficial effects that effective supporting and door opening re-digging are completed, safety and reliability are achieved, overall digging of the large-span door opening is guaranteed, segmented construction is avoided, construction joints and leakage risks are reduced, the construction period is shortened, and the cost is reduced.
本发明公开了地铁车站附属与主体连接段地墙门洞的结构及其施工工艺，包括车站主体结构与车站附属结构，车站主体结构与车站附属结构上端分别设有主体结构顶板与附属结构顶板，其下端分别设有主体结构中板与附属结构底板，主体结构顶板上端设有压顶梁、地下连续墙、冠梁与砼支撑，砼支撑上方为临时道路，其工艺：保留连接段范围主体基坑首道砼支撑及冠梁；增设压顶梁；附属基坑开挖；附属结构底板施工，增加施工下凹传力板带；附属结构侧墙、顶板施工；整体开凿连接段地墙门洞；连接段后浇段施工，本发明的有益效果：完成有效的支撑，再开凿门洞，安全可靠，保证大跨度门洞的整体开凿，避免分段施工，减少施工缝及渗漏风险，节省工期和成本。
