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.
Description
technical field [0001] The patent of the present invention relates to the technical field of foundation pit construction, in particular, to an underground pipe culvert foundation pit excavation and support construction method by reverse method. Background technique [0002] With the advancement of the rapid urban construction and the acceleration of the upgrading and transformation of old urban areas, the biggest problem faced in the process of infrastructure construction such as underground pipes and culverts is the treatment and protection of existing underground pipelines. [0003] Due to the long history of construction in the old urban area and the irregular or lack of management of pipelines in the past, there is a lack of systematic and accurate data on the distribution of various pipelines. Before the later construction, although measures will be taken to further identify the distribution of pipelines, technical means Due to the limitation of the pipeline, there are ...
