Inner support foundation pit site earthwork layered excavation construction method
The invention relates to the technical field of earthwork layered excavation, and discloses an inner support foundation pit site earthwork layered excavation construction method, which comprises the following steps: 1) collecting landmark height data and survey data of a re-check construction site, carrying out early-stage technical planning, establishing a three-dimensional geologic model of the construction site, and planning an awning area and a sealing plate area; (2) a plurality of peripheral supporting piles are constructed on the periphery of the construction site, a plurality of stand column piles are constructed in the construction site, and top beams are arranged at the tops of the peripheral supporting piles; a first-layer area is excavated in the construction site, and first-layer supporting beams are constructed; (3) a curtain which can be movably laid above the foundation pit is arranged on the sky curtain area, and construction is conducted between the first-layer supporting beams to form a sealing cover plate; (4) downward excavation construction is carried out to form a lower area, a trestle ramp is arranged in the lower area, the trestle ramp is arranged in an inclined mode, and construction is carried out at the bottom of the lower area to form a lower supporting beam; and (5) the construction step (4) is repeated till the excavation depth reaches the set depth of the foundation pit.
本发明涉及土方分层开挖的技术领域，公开了内支撑基坑场地土方分层开挖施工方法，包括：1)、收集复核施工场地现场的地标高数据以及勘察数据，进行前期技术策划，建立施工场地的三维地质模型并策划天幕区以及封板区；2)、在施工场地的外周施工多个外周支护桩，在施工场地中施工多个立柱桩，多个外周支护桩的顶部设有冠梁；在施工场地开挖首层区域，并施工首层支撑梁；3)、在天幕区上布置可活动铺盖在基坑上方的幕布，在首层支撑梁之间施工形成封盖板；4)、朝下开挖施工形成下部区域，在下部区域中布置栈桥坡道，栈桥坡道呈倾斜布置，且在下部区域的底部施工形成下部支撑梁；5)、重复施工步骤4)，直至开挖深度达到基坑的设定深度。
