Pile foundation constraint structure
The invention relates to the technical field of pile foundation reinforcement, in particular to a pile foundation constraint structure which is a prefabricated integrated structure and comprises a sleeve suitable for being arranged outside a pile foundation in a sleeving mode; the number of the auxiliary piles is at least one set, one set of the auxiliary piles comprises a plurality of auxiliary piles which are evenly distributed in the circumferential direction of the casing pipe at intervals, every two adjacent auxiliary piles in one set of the auxiliary piles are connected through a first connecting rib, and the auxiliary piles are connected with the casing pipe or the two adjacent auxiliary piles located on different circles through second connecting ribs; the second connecting rib comprises an elastic part, the auxiliary pile comprises a pile body with a pile core hole and a reinforcing rib located below the pile body, and after the pile foundation constraint structure is hoisted in place, the reinforcing rib is suitable for being embedded into a hard soil layer with the designed depth under gravity and ballast force, and the pile body is suitable for being embedded into a soft soil layer. The pile foundation constraint structure can effectively reduce the construction period and the construction difficulty, and can better adapt to the construction action conditions of short offshore wind power window period and large water depth.
本发明涉及桩基加固技术领域，具体涉及一种桩基约束结构，为预制一体化结构，包括：套管，适于套设在桩基外；辅助桩，设有至少一组，一组辅助桩包括多个沿所述套管的周向均匀且间隔分布的辅助桩，一组辅助桩中相邻的两个辅助桩通过第一连接筋相连，所述辅助桩与所述套管或者是位于不同圆的相邻两个所述辅助桩之间通过第二连接筋相连，所述第二连接筋包括弹性部，所述辅助桩包括具有桩芯孔的桩体和位于所述桩体下方的加强筋，所述桩基约束结构吊装到位后，在重力以及压载力下，所述加强筋适于嵌入设计深度硬土层，所述桩体适于嵌入软土层。该桩基约束结构可有效减少工期和施工难度，更好适应海上风电窗口期短和水深大的施工作用条件。
