Underground pipe culvert foundation pit reverse construction method excavation support construction method
The invention relates to the technical field of foundation pit construction, and discloses an underground pipe culvert foundation pit reverse construction method excavation supporting construction method which comprises the following construction steps that (1) the excavation position of a foundation pit is determined; (2) a top section support is constructed at the excavation position of the foundation pit, a top beam is formed through construction, and a plurality of top section supporting beams are formed through construction; (3) a lower section support is constructed downwards; a wall protection layer is formed through construction, and a plurality of vertical rib beams are formed on the wall protection layer; (4) the step (3) is repeated until the foundation pit is constructed to the set elevation; (5) a formwork construction underground pipe culvert is arranged on a cushion layer at the bottom of the foundation pit; a foundation pit is excavated section by section by adopting a top-down reverse construction method, a top section supporting beam and a top beam are adopted for supporting in a top section support, a retaining wall layer, a vertical rib beam and the like are adopted for supporting in a plurality of subsequent lower section supports, and in the process of excavating the foundation pit section by section, underground pipelines are convenient to expose and prevented from being damaged; the construction period is shortened, the cost is saved, and remarkable social and economic benefits are obtained.
本发明涉及基坑施工的技术领域，公开了地下管涵基坑逆作法开挖支护施工方法，包括以下施工步骤：1)、确定基坑开挖位置；2)、在基坑开挖位置施工顶节支护，施工形成冠梁，施工形成多个顶节支撑梁；3)、往下施工下节支护；施工形成护壁层，护壁层上形成有多个竖向肋梁；4)、重复施工所述步骤3)，直至基坑施工至设定标高；5)、在基坑底部的垫层是支模施工地下管涵；采用自上而下逆作法逐节开挖基坑，顶节支护中，采用顶节支撑梁以及冠梁进行支护，后续的多个下节支护中，采用护壁层以及竖向肋梁等进行支护，在逐节开挖基坑的过程中，便于地下管线的显露，避免地下管线被破坏，安全可靠、缩短工期、节省成本，取得显著的社会和经济效益。
