Construction method for backfilling sand and gravel above subway station
The invention discloses a construction method for backfilling sand and gravel above a subway station. The construction method for backfilling sand and gravel above the subway station comprises the steps that a, ground vegetation is removed; b, the square section to be constructed is divided into a plurality of square construction units; c, a first reference road and a second reference road are laid; d, four staggered starting points are arranged, and construction is started; and e, when L square construction units to be constructed exist between the square construction units which are laid with sand and gravel at two ends of the same row, two construction lines with the same construction direction are stopped, and the construction of the remaining two construction lines is kept until the entire square section is laid with the sand and gravel. Simultaneous construction of the two construction routes in the same direction in the same row is avoided. A basic construction unit is divided into four unconnected blocks to prevent the situation that a waterproof layer and a safety structure of a subway frame are prone to being damaged during simultaneous large-area construction due to thefact that the covering depth of a roof of a station tunnel is shallow.
本发明公开了一种地铁车站上方回填砂砾石的施工方法，包括步骤：a.清除地表植被；b.将待施工的方形路段划分为多个方形施工单位；c.铺设第一基准路面和第二基准路面；d.设置四个相错开的起点，开始施工；e.当同一行两端的已铺设砂砾石方形施工单元之间间隔有L个待施工的方形施工单元时，停止两条施工方向相同的施工线路，剩余的两条施工线路保持施工，直至整个方形路段均已铺设砂砾石，避免了同一方向上的两条施工路线在同一列同时施工，将基本施工单位分为四块不相接的块状，防止因车站隧道顶板覆土深度较浅，同时进行大面积施工时容易破坏地铁框架防水层和安全结构。
