利用钢管膨胀的地锚兼用排水管及其设置方法
摘要：
本发明提供一种地锚兼用排水管及其设置方法，地锚兼用排水管具备：（i）膨胀性钢管，具有通过前端注入压力流体的中空部，呈一部分沿周长方向凹陷的形态；（ii）连接部，包括第一结合部与第二结合部，第一结合部位于膨胀性钢管的前端，具有第一直径，第二结合部连接到第一结合部，位于远离膨胀性钢管的前端的方向，且具有小于第一直径的第二直径，具有通过第一结合部的中心与第二结合部的中心而连接到膨胀性钢管的中空部的贯通孔；（iii）有孔排水管，一侧结合到连接部的第一结合部，内部为中空，且具有连接内部与外部的多个排水孔；以及（iv）流体注入管，一侧通过有孔排水管的内部而以可装卸的方式结合到连接部的第二结合部。
摘要（英）：

The invention provides a ground anchor dual-purpose drainage pipe and a setting method thereof. The ground anchor dual-purpose drainage pipe has (i) an expansion steel pipe having a hollow part having the front end injected with pressure fluid, and having a part in the state of recessing along the circumference direction; (ii) a connection part including a first connection and a second connection part, the first connection part is located at the front end of the expansion steel pipe and has a first diameter and the second connection part is connected to the first connection part in a direction away from the front end of the expansion steel pipe and has a second diameter smaller than the first diameter, and has a through hole that is connected to the hollow portion of the expansion steel pipe by passing through the center of the first connection part and the center of the second connection part; (iii) a perforated drain pipe, one side of which is coupled to the first connection part of the connection part, the inside of which is hollow and has a plurality of drainage holes connecting the inside with the outside; and (iv) a fluid injection pipe which is detachably coupled to the second connection part of the connection part through the inside of the perforated drain pipe.
