Construction method for seamless connection of reinforced concrete trestle and earthwork ramp
The invention relates to the technical field of earthwork ramps, and discloses a construction method for seamless connection of a reinforced concrete trestle and an earthwork ramp, which comprises the following construction steps: 1) planning a foundation pit layout on a construction site to form a foundation pit area, and constructing in the foundation pit area to form a plurality of latticed columns; (2) a formwork is arranged on the foundation pit area, a trestle steel bar frame is placed, concrete is poured, maintenance is completed, a reinforced concrete trestle is formed, and the bottom of the reinforced concrete trestle abuts against the tops of the latticed columns; (3) a soil body is excavated in the foundation pit area to form a foundation pit, an earthwork ramp is formed in the foundation pit, the earthwork ramp is in butt joint with the reinforced concrete trestle to form a traffic lane, and the soil body is transported out of the foundation pit through a carrier loader; when the foundation pit is excavated to the set depth, an inner support is constructed in the foundation pit until the foundation pit is excavated to the set depth of the pit bottom; (4) the earthwork ramp is dismantled in a layered mode; (5) a construction platform is arranged on the steel-concrete trestle, and a grab bucket machine is used for grabbing and outwards transporting a soil body formed by dismantling the earthwork ramp; and (6) the reinforced concrete trestle is dismantled.
本发明涉及土方坡道的技术领域，公开了钢混栈桥与土方坡道无缝衔接的施工方法，包括以下施工步骤：1)、在施工场地规划基坑布局，形成基坑区域，基坑区域中施工形成有多个格构柱；2)、在基坑区域上设置模板、放置栈桥钢筋架以及浇注混凝土，养护完成，形成钢混栈桥，钢混栈桥的底部抵接在格构柱的顶部；3)、在基坑区域中开挖土体，形成基坑，基坑中形成有土方坡道，土方坡道与钢混栈桥对接，形成通车道，利用运载车将土体运出基坑；当基坑开挖至设定深度时，在基坑中施工内支撑，直至基坑开挖至坑底设定深度；4)、分层拆除土方坡道；5)、钢混栈桥上设置施工平台，利用抓斗机将拆除土方坡道形成的土体进行抓取外运；6)、拆除钢混栈桥。
