Steel pipe cement composite pile and pile forming method and test method thereof
The invention provides a steel pipe cement composite pile and a pile forming method and a test method thereof. The pile forming method of the steel pipe cement composite pile comprises the steps thatstep S10, an outer steel pipe is driven into a soil layer in the vertical direction; and step S20, the soil layer in the outer steel pipe is drilled in the vertical direction to form vertical pile holes; step S30, a inner steel pipe is lowered into the vertical pile holes in the vertical direction, and the bottom of the inner steel pipe is connected with a sealing plate, and the lower end of the inner steel pipe is lowered to the lower part of the outer steel pipe; and step S40, cement is poured into the vertical pile holes to form a well cementation cement ring located under the outer steel pipe and surrounding the inner steel pipe and an annulus cement ring located between the outer steel pipe and the inner steel pipe. The technical problems of poor lateral toughness and settlement of apile foundation in the prior art are solved.
本发明提供了一种钢管水泥复合桩及其成桩方法和测试方法，该钢管水泥复合桩的成桩方法，包括：步骤S10，沿竖直方向将外层钢管打入土层；步骤S20，沿竖直方向对所述外层钢管内的土层进行钻孔，形成竖直桩孔；步骤S30，沿竖直方向将内层钢管下入竖直桩孔中，所述内层钢管的底部连接有封板，所述内层钢管的下端下入至所述外层钢管的下方；步骤S40，向所述竖直桩孔内灌注水泥，以形成位于所述外层钢管的下方且包围所述内层钢管的固井水泥环、和位于所述外层钢管与所述内层钢管之间的环空水泥环。通过本发明，缓解了现有技术中的桩基基础沉降与侧向韧性性能较差的技术问题。
