Construction method of inclined precast pile inclined strut
The construction method comprises the steps that (1) fender posts and a top beam are constructed, anchoring ribs are pre-buried in the top beam, and inclined anchoring holes are reserved in the top beam; (2) the static pressure pile machine is installed on the top beam through anchoring ribs; (3) the precast pile sinks underground through a static pressure pile machine and forms an inclined strut; (4) a first concrete grouting material is poured between the anchoring pile and the anchoring hole, and after the strength of the first concrete grouting material reaches the first set strength, the static pressure pile machine is dismantled; (5) after construction of all the inclined struts is completed, earthwork is excavated, and an underground structure is constructed; and when the strength of the bottom plate of the underground structure reaches the second set strength or above, the inclined strut located between the top beam and the bottom plate is dismantled. The static pressure pile machine with light self weight is installed on the top beam, counter force is provided by the top beam for construction, the construction cost is reduced, the construction convenience is improved, piles with large inclination can be constructed, and the stability of a foundation pit support is guaranteed.
本申请公开了一种倾斜预制桩斜撑的施工方法，步骤为：(1)施工围护桩和冠梁，并在冠梁内预埋锚固筋和预留倾斜的锚固孔；(2)将静压桩机经锚固筋安装在冠梁上；(3)预制桩经静压桩机下沉到地下并形成为斜撑；(4)在锚固桩与锚固孔之间浇注第一混凝土灌浆料，待第一混凝土灌浆料的强度达到第一设定强度后，拆除静压桩机；(5)在完成所有斜撑的施工后，开挖土方并施工地下结构；当地下结构的底板的强度达到第二设定强度以上时，将位于冠梁与底板之间的斜撑拆除。本申请将自重较轻的静压桩机安装在冠梁上，以冠梁提供反力进行施工，降低施工费用，提高施工便利性，能够施工大倾斜度的桩，保证基坑围护的稳定性。
