Construction method of embedded anchorage device structure for reducing excavation volume of foundation pit
The invention relates to the field of foundation pit excavation, and discloses a construction method of an embedded anchorage device structure for reducing the excavation volume of a foundation pit, which comprises the following steps: step 1, preparing an embedded part and a reinforcement cage, and mounting the embedded part on a main reinforcement of the reinforcement cage; an operation cavity is formed in the embedded part, a drilling opening is formed in the side, close to the center of the reinforcement cage, of the embedded part, and a drilling tool penetrates through the drilling opening; secondly, a reinforcement cage is placed in the pile hole, and pile body concrete is poured; thirdly, a foundation pit is excavated, an embedded part is found, an anchor hole is drilled in the position of a drilling opening, an anchor cable is placed in the anchor hole, and grouting is conducted on the anchor hole; fourthly, a pressure-bearing piece and an anchorage device are sequentially placed on the drilling opening, the outer diameter of the pressure-bearing piece is larger than that of the drilling opening, a first containing hole is formed in the pressure-bearing piece, the inner diameter of the first containing hole is smaller than that of the anchorage device, the steel cable sequentially penetrates through the drilling opening, the first containing hole and the anchorage device, the anchor cable is tensioned, and the anchor is sealed. A fertilizer groove filling layer is omitted, foundation pit excavation is reduced, the environment is protected, and green, energy-saving and low-carbon effects are achieved.
本发明涉及基坑开挖领域，公开了一种用于减少基坑开挖量的嵌入式锚具结构施工方法，步骤一、准备嵌入部件和钢筋笼，将嵌入部件安装在钢筋笼的主筋上；嵌入部件内设有操作腔，嵌入部件靠近钢筋笼中心一侧开有钻孔口，钻孔口用于供钻具穿过；步骤二、将钢筋笼放入桩孔中，浇筑桩体混凝土；步骤三、开挖基坑，找到嵌入部件，在钻孔口位置钻锚孔，在锚孔内放入锚索，锚孔注浆；步骤四、在钻孔口上依次放上承压件和锚具，承压件的外径大于钻孔口，承压件上设有第一容纳孔，第一容纳孔的内径小于锚具，钢索依次穿过钻孔口、第一容纳孔和锚具，张拉锚索，封锚。以取消肥槽填充层，减少基坑开挖，保护环境，绿色节能低碳。
