Foundation pit engineering axial force servo inclined pile support and construction method thereof
The invention discloses a foundation pit engineering axial force servo inclined pile support and a construction method thereof, and aims to provide a foundation pit engineering axial force servo inclined pile support capable of optimizing construction process steps and shortening the construction period; according to the foundation pit engineering axial force servo batter pile support and the construction method thereof, foundation pit deformation can be actively controlled, and the problem that the batter pile supporting effect is weakened due to compression deformation of a batter pile bottom soil body is effectively solved. A foundation pit engineering axial force servo inclined pile support comprises a foundation pit fender post, and a coping beam is arranged at the top of the foundation pit fender post; the inclined pile comprises a supporting inclined pile and a top inclined pile, the upper end of the top inclined pile and the capping beam are connected into a whole, and the supporting inclined pile is inserted into the foundation pit soil body; the servo loading device comprises a jack, the jack is located between the lower end of the top batter pile and the upper end of the supporting batter pile, and the jack applies axial force between the top batter pile and the supporting batter pile in the axial direction of the batter pile, so that a foundation pit soil body at the pile bottom of the supporting batter pile is actively compressed.
本发明公开了一种基坑工程轴力伺服斜桩支撑及其施工方法，旨在提供一种不仅能够优化施工工艺步骤，缩短施工周期；而且能够主动控制基坑变形，有效避免因斜桩底土体压缩变形，而削弱斜桩支护效果的问题的基坑工程轴力伺服斜桩支撑及其施工方法。一种基坑工程轴力伺服斜桩支撑，包括：基坑围护桩，基坑围护桩的顶部设有压顶梁；斜桩，斜桩包括支撑斜桩与顶部斜桩，其中，顶部斜桩的上端与压顶梁连为一体，支撑斜桩插设在基坑土体内；伺服加载装置，伺服加载装置包括千斤顶，千斤顶位于顶部斜桩的下端与支撑斜桩的上端之间，千斤顶沿斜桩轴向在顶部斜桩与支撑斜桩之间施加轴力，从而主动压缩支撑斜桩的桩底的基坑土体。
