Construction method for enclosing purlin reinforced detachable anchor cable fender pile
The invention discloses a construction method of a detachable anchor cable fender pile for enclosing purlin reinforcement. The construction method comprises the following steps that S1, a foundation pit is excavated; s2, a hole is drilled in a rock stratum in the wall of the foundation pit, and then the procedures of anchor cable weaving, anchor cable installing, grouting, tensioning and anchor sealing are sequentially constructed; s3, I-shaped steel in the underground diaphragm wall is chiseled out at the position of the pit wall of the foundation pit, triangular supports are fixedly installed on the outer side of the I-shaped steel, the triangular supports are arranged in rows along the pit wall of the foundation pit, and then surrounding purlins are fixedly installed on the triangular supports arranged in rows; in the step, it is guaranteed that the enclosing purlins are located on the outer sides of all the pile bodies; s4, steel tie beams are erected between the surrounding purlins; s5, the inter-pile plates are constructed; and the step S1 to the step S5 are repeated, and the foundation pit is excavated downwards layer by layer. The foundation pit supporting structure has the beneficial effects that the foundation pit supporting structure has good supporting strength and higher safety and reliability, and the technical problem that a spiral stressed steel bar of a supporting pile is damaged due to anchor cable drilling construction is solved.
本发明公开了一种围檩加固可拆卸式锚索护桩施工方法,包括以下步骤:S1:开挖基坑;S2:在基坑坑壁上向岩层内钻孔,然后依次施工锚索编制、装锚索、灌浆、张拉和封锚工序;S3:在基坑坑壁位置凿出地连墙内的工字钢,再在工字钢的外侧固定安装三角支架,三角支架沿基坑坑壁呈排布置,然后将围檩固定安装在呈排布置的三角支架上;在该步骤中,要保证围檩位于各个桩身外侧;S4:在所述围檩之间架设钢系梁;S5:施工桩间板;重复所述步骤S1至S5,逐层向下开挖基坑。本发明的有益效果是:基坑支护结构具有很好的支护强度,安全可靠性更高,且解决了因锚索钻孔施工破坏支护桩螺旋受力钢筋的技术问题。
