Foundation pit permanent support pile wall and construction method thereof
The invention discloses a foundation pit permanent support pile wall and a construction method thereof, and belongs to the field of building construction. Comprising an enclosure structure formed by alternately arranging support piles and cement-soil stirring walls; the supporting pile comprises a pile body which is located in a pile hole formed before excavation of a foundation pit and is vertically arranged, the pile body comprises an upper pile body and a lower pile body, the upper pile body is a cuboid cylinder, and the lower pile body is a cylindrical body; an expansion body section is arranged between the upper pile body and the lower pile body, and the size of the cross section of the expansion body section is larger than that of the cross sections of the upper pile body and the lower pile body; the upper pile body, the expansion body section and the lower pile body are sequentially arranged in the pile hole from top to bottom and are integrally formed; the expansion body section and the lower pile body are located below the bottom face of the excavated foundation pit, and the upper pile body is located above the bottom face of the excavated foundation pit. The flatness, the perpendicularity and the supporting capacity of the permanent supporting pile wall are improved.
本发明公开了一种基坑永久支护桩墙及其施工方法，属于建筑施工领域。包括由支护桩和水泥土搅拌墙交替排列形成的围护结构；该支护桩包括位于在基坑挖掘前已成型的桩孔内且竖向设置的桩身，该桩身包括上部桩身和下部桩身，上部桩身为长方体柱形体，下部桩身为圆柱形体；上部桩身和下部桩身之间具有扩体段，扩体段的横截面尺寸大于上部桩身和下部桩身的横截面尺寸；上部桩身、扩体段和下部桩身在桩孔内从上到下依次设置且整体成型；扩体段和下部桩身位于挖掘后的基坑的底面的下方，上部桩身位于挖掘后的基坑的底面的上方。本发明提高了永久支护桩墙的平整度、垂直度和支护能力。
