Forward and reverse combined construction method for basement spring layer excavation
The invention discloses a forward and reverse combined construction method for basement spring layer excavation, and relates to the technical field of construction methods of basement structures adopting a reverse construction method.According to the technical scheme, after construction of structural beam plates of a construction layer is completed every time, a second layer is excavated from the lower portion of the construction layer to the layer + 2, structural beam plates of the layer + 2 are poured, and the structural beam plates of the layer + 2 are poured; and then a first-layer structure is sequentially manufactured above the second layer of the current layer, two layers continue to be excavated downwards in a skip-layer mode below the second layer of the current layer, and construction is circularly conducted in sequence till completion. The method has the beneficial effects that when a basement structure is constructed through a reverse construction method, layer-by-layer excavation and layer-by-layer structure construction are usually carried out, and the difficult problems of small mechanical operation space, low formwork erecting height, high construction difficulty and long construction period often exist in the construction process, the scheme provides the method for realizing forward and reverse combination through spring layer excavation when the basement is constructed through the reverse construction method; therefore, construction difficulty is reduced and construction period is effectively shortened.
本发明公开了一种地下室跃层开挖顺逆结合施工方法，涉及采用逆作法的地下室结构的施工方法技术领域，技术方案为，每次在施工层本层结构梁板施工完成后，施工层本层下方开挖2层至本层+2层，浇筑本层+2层结构梁板，之后在本层+2层上方顺做1层结构，本层+2层下方继续向下跃层开挖两层，依此循环施工至完成。本发明的有益效果是：逆作法施工地下室结构时，通常是逐层开挖并逐层施工结构，施工过程中常常面临机械操作空间小、支模高度矮，施工难度大，工期长的难题，本方案提供一种逆作法施工地下室时可以采用跃层开挖实现顺逆结合的方法，从而降低施工难度，有效缩短工期。
