Mixed supporting retaining wall structure and construction method thereof
The invention relates to the field of mixed retaining, and discloses a mixed retaining wall structure which is suitable for excavating a foundation pit (30 m or above) with a very large depth and comprises a supporting pile, the supporting pile comprises a cantilever section and a built-in section, the cantilever section supports the upper portion of a slope and is provided with a pile anchor, the built-in section is buried in the lower portion of the slope, and a platform is arranged between the built-in section and the cantilever section. And a side slope support is arranged on the lower part of the side slope. The construction method of the mixed supporting retaining wall structure comprises the following steps that firstly, structure checking calculation is conducted; secondly, supporting piles are constructed; thirdly, the soil body in front of the pile is excavated downwards to the elevation of the platform through a reverse construction method, and meanwhile pile anchors are constructed; and 4, a construction platform is constructed, downward slope cutting construction is conducted to the bottom of the foundation pit through a reverse construction method, and meanwhile slope supports are constructed on the lower portion of the slope.
本发明涉及混合支挡领域，公开了一种混合支挡墙结构，适用于开挖深度特别深的基坑(30m以上)，包括支护桩，支护桩包括悬臂段和嵌固段，悬臂段支挡边坡上部并设有桩锚，嵌固段埋在边坡下部中，嵌固段和悬挑段之间设有平台，边坡下部上设有边坡支护。一种混合支挡墙结构的施工方法，包括以下步骤：步骤一、进行结构验算；步骤二、施工支护桩；步骤三、逆作法向下开挖桩前土体至平台标高，同时施工桩锚；步骤四、施工平台，逆作法向下削坡施工至基坑底部，同时对边坡下部施工边坡支护。
