Expanded-base steel pipe pile and construction technology thereof
The invention relates to the technical field of building construction, in particular to an expanded-base steel pipe pile and a construction technology thereof.The expanded-base steel pipe pile comprises a pile core steel pipe and an expanded wing plate, one end of the pile core steel pipe is a connector end, a force transmission piece of the connector end is connected with a force transmission part, and the force transmission part is connected with the power end of drilling machine equipment; the other end of the pile core steel pipe is a drilling-in end, and the drilling-in end is connected with a wing expanding plate so that the pile core steel pipe can be rotatably cut into soil through the wing expanding plate; an injection cavity is formed in the pile core steel pipe. The expanded-base steel pipe pile can provide large bearing capacity with a small diameter, is suitable for different types of soil and rock including soft soil, sandy soil, cohesive soil, soft rock and the like, and meanwhile has the advantages of being high in construction efficiency, capable of forming the pile at a time, free of slurry, free of dumping, capable of saving energy, environmentally friendly, short in rest period, moderate in soil squeezing, capable of improving side friction resistance, low in comprehensive manufacturing cost and the like.
本发明涉及建筑施工技术领域，更具体地说，涉及一种扩底钢管桩及其施工工艺，包括：桩芯钢管和扩翼板，桩芯钢管一端为接头端，接头端的传力件连接传力部，传力部与钻机设备的动力端连接；桩芯钢管另一端为钻入端，钻入端连接有扩翼板，以通过扩翼板旋转切削入土；桩芯钢管内设有注入腔。本发明的扩底钢管桩，能够以较小直径提供较大的承载力，适用于不同类型的土壤和岩石，包括软土、砂土、黏性土、软岩等，同时具有施工效率高、一次成桩、无泥浆、无需排土、节能环保、休止期短、适度挤土、提高侧摩阻力、综合造价低等优点。
