Steel sleeve for secant pile plain pile construction, secant pile, and secant pile construction method
The invention provides a steel sleeve for secant pile plain pile construction. The steel sleeve comprises a steel sleeve body arranged between two piles with reinforcing steel bars; the steel sleeve body comprises two oppositely-arranged first arc-shaped parts and two oppositely-arranged second arc-shaped parts; and the two first arc-shaped parts and the two second arc-shaped parts enclose to form the steel sleeve body. The two first arc-shaped parts are formed by inwards concaving the side wall of the steel sleeve body; the two first arc-shaped parts are tightly attached to the piles with reinforcing steel bars adjacent to the first arc-shaped parts correspondingly; and the circle centers of the cross sections of the two first arc-shaped parts coincide with the circle centers of the cross sections of the piles with reinforcing steel bars adjacent to the first arc-shaped parts correspondingly, so that tight meshing of secant piles is guaranteed. The invention further provides the secant pile. The secant pile comprises a plurality of plain piles and the multiple piles with reinforcing steel bars; the plain piles are constructed through the steel sleeve used for secant pile plain pile construction; the multiple plain piles and the multiple piles with reinforcing steel bars are linearly distributed and arranged in a staggered mode; and the adjacent plain piles and the piles with reinforcing steel bars are meshed. The invention further provides a secant pile construction method.
本发明提供一种用于咬合桩素桩施工的钢套筒，包括设于两个荤桩之间的钢套筒本体，所述钢套筒本体包括相对设置的两个第一弧形部、相对设置的两个第二弧形部，两所述第一弧形部以及两所述第二弧形部围合成钢套筒本体，两所述第一弧形部由钢套筒本体的侧壁内凹形成，两所述第一弧形部分别与之紧邻的荤桩紧密贴合，两所述第一弧形部横截面的圆心分别与之紧邻的荤桩横截面的圆心重合，以保证咬合桩的紧密咬合。本发明还提供一种咬合桩，包括若干素桩和若干荤桩，所述素桩采用上述的用于咬合桩素桩施工的钢套筒施工，若干素桩和若干荤桩呈直线分布，素桩和荤桩交错设置，相邻素桩和荤桩之间相咬合。本发明还提供一种咬合桩施工方法。
