Soil retaining structure suitable for eliminating frost heaving effect in cold region and construction method
The invention provides a soil retaining structure suitable for eliminating a frost heaving effect in a cold region and a construction method. The soil retaining structure comprises a slope protection backfill material, an EPS-containing mixed structure, a wall heel clay layer, a retaining wall, a drainage hole, a rigid pull rod and an anchoring plate; a through drainage hole is formed in the upper portion, the middle portion and the lower portion of the retaining wall body; the backfilling structure for eliminating the frost heaving effect is tightly attached to the wall back; the left ends of the rigid pull rods are embedded into the retaining wall, and the right ends of the rigid pull rods transversely penetrate through the EPS light soil to be connected with the anchoring plate in the soil embedded behind the wall; and the construction method comprises the following steps of construction preparation, foundation trench excavation and construction working face building, construction of the retaining wall and the backfill structure behind the wall, construction of the rigid pull rod and construction of the EPS-contained mixed structure. The structure is suitable for soil slope reinforcement engineering or high fill engineering needing to reduce or eliminate the frost heaving effect in infrastructure construction in the cold region, and has the advantages of being simple in structural form, easy and convenient to construct and low in engineering cost.
本发明提供了一种适用于寒区消除冻胀效应的挡土结构及施工方法，所述挡土结构包括护坡回填料、含EPS混合结构、墙踵黏土层、挡土墙、排水孔、刚性拉杆和锚定板；挡土墙墙身在上、中和下部分别设置贯通的排水孔；消除冻胀效应的回填结构紧贴附于墙背；刚性拉杆通过布设钢筋相连，左端嵌入挡土墙内，右端横向贯穿EPS轻质土与埋置墙后土中锚定板相连；所述施工方法包括以下步骤：进行施工准备→进行基槽开挖，搭建施工工作面→对挡土墙及墙后回填结构进行施工→对刚性拉杆进行施工→对含EPS混合结构进行施工。本发明适用于寒区基础设施建设中需降低或消除冻胀效应的土质边坡加固工程或高填方工程，具有结构形式简单，施工方法简便，工程造价低的优点。
