Construction method of concealed anchor sealing structure
The invention relates to the technical field of slope support and landslide control engineering, and discloses a construction method of a concealed anchor sealing structure. The construction method comprises the following steps that hole forming construction is carried out on a support pile, and a pile body reinforcement cage is machined; a steel sleeve is embedded in the position where an anchor cable is designed; a temporary formwork is embedded; a soil body in front of the support pile is excavated, a soil body on the outer side of the temporary formwork is excavated, and a temporary cavity is formed; the temporary formwork is removed; the anchor cable is constructed in the temporary cavity, the anchor cable is embedded in the steel sleeve, and grouting is carried out in the steel sleeve; the anchor cable is tensioned and locked; anchor sealing concrete is poured into the temporary cavity; firstly, the steel sleeve is embedded, the anchor cable can be conveniently installed in the steel sleeve in the later period, then the soil body is excavated, the temporary cavity is formed in the support pile, and therefore the anchor cable can be conveniently installed; and after the temporary cavity is filled with concrete, the anchor cable can be concealed in the support pile, on the premise that the section size, namely the pile body strength, of the support pile is not weakened, the anchor cable is concealed in the support pile, and the landscape effect of the support structure can be improved in the later greening stage.
本发明涉及边坡支护、滑坡治理工程的技术领域，公开了暗埋式封锚结构的施工方法，包括以下步骤：支护桩成孔施工，加工桩身钢筋笼；在设计锚索位置处预埋钢套管；预埋临时模板；开挖支护桩桩前土体，并开挖临时模板外侧的土体，形成临时凹腔；拆除临时模板；在临时凹腔内施工锚索，所述锚索嵌入在钢套管内，往所述钢套管内注浆；锚索张拉锁定；往临时凹腔内浇筑封锚混凝土；首先预埋钢套管，便于后续将锚索安装在钢套管内，随后开挖土体，在支护桩上形成临时凹腔，这样便于安装锚索，且当将临时凹腔用混凝土填充后，即可将锚索暗埋在支护桩内，在不削弱支护桩截面尺寸即桩身强度的前提下，将锚索暗埋在支护桩内，有利于后期绿化阶段提升支护结构的景观效果。
