Anti-scouring roadbed construction method and structure
The embodiment of the invention discloses an anti-scouring roadbed construction method which comprises the following steps that a reverse step is excavated on a side slope in the inclination direction of a slope surface, and the reverse step extends to the top of the side slope from the bottom of the side slope; rib columns are constructed at intervals in the flow direction of the river channel, soil retaining plates are installed on the sides, close to the side slope, of the adjacent rib columns, a rib column type retaining wall is formed, and the rib column type retaining wall and the side slope form a soil filling space; a protection foundation is arranged at the bottom of each rib column, and anchor holes are reserved in the rib columns; foam light soil is poured in the soil filling space in a layered mode according to the preset layer height, reinforcing layers are laid layer by layer, and an impermeable layer is laid on the top layer of the foam light soil; anchoring parts are installed through anchor holes reserved in the rib columns; and a pavement structure layer is constructed above the soil filling space so as to seal and cover the soil filling space and form the anti-scouring roadbed. The basic structure of the roadbed is mainly formed by the rib column type retaining wall composed of the rib columns and the soil retaining plates and the slope, and the scouring effect of water flow is effectively reduced by means of the column structure.
本申请的实施例公开了一种抗冲刷路基建造方法，包括以下步骤：在边坡上沿坡面的倾斜方向开挖反向台阶，其中，反向台阶自边坡的底部延伸至边坡的顶部；沿河道流向间隔施工肋柱并在相邻的肋柱靠近边坡的一侧安装挡土板，形成肋柱式挡土墙，使得肋柱式挡土墙与边坡构成填土空间；每个肋柱的底部设置有保护基础，肋柱上预留有锚孔；以预设层高在填土空间中分层浇筑泡沫轻质土并逐层铺设加固层，并在泡沫轻质土的顶层铺设防渗层；通过肋柱上预留的锚孔安装锚固件；在填土空间的上方施工路面结构层，以封盖填土空间并形成抗冲刷路基。本申请主要通过肋柱和挡土板构成的肋柱式挡土墙与边坡形成路基的基本结构，并借助柱结构有效减小了水流的冲刷作用。
