Grouting system for enhancing bearing capacity of offshore wind power pile foundation and construction method
The invention provides a grouting system for enhancing the bearing capacity of an offshore wind power pile foundation and a construction method. The grouting system comprises a pipeline installation structure used for installing the grouting system, the grouting system comprises a pile side grouting system used for conducting grouting on the outer side wall of a cast-in-place pile and a pile bottom grouting system used for conducting grouting on the pile bottom of the cast-in-place pile, the pile side grouting system is connected to the grouting system, grout is injected into a pile side gap between the outer side wall of the cast-in-place pile and a seabed foundation layer, the pile bottom grouting system is connected to the grouting system and injects the grout into a pile bottom gap between the pile bottom of the cast-in-place pile and the seabed foundation layer. By the adoption of the grouting system, secondary grouting can be conducted after pouring of the cast-in-place pile is completed, permeation and splitting effects are generated on a pile body and a nearby soil body through the grout, then solidification is conducted, and therefore the effect of increasing the bearing capacity is achieved.
本发明提供了一种加强海上风电桩基础承载力的注浆系统及施工方法，它包括用于安装所述注浆系统的管线安装结构；所述注浆系统包括用于对于灌注桩的外侧壁进行注浆的桩侧注浆系统和用于对灌注桩的桩底进行注浆的桩底注浆系统；所述桩侧注浆系统与注浆系统相连，并将浆液注入到灌注桩的外侧壁与海床基础层之间的桩侧间隙；所述桩底注浆系统与注浆系统相连，并将浆液注入到灌注桩的桩底和海床基础层之间的桩底间隙。通过采用上述的注浆系统，能够在灌注桩浇筑完成之后，进行二次注浆，通过浆液对桩身及附近土体产生渗透、劈裂作用，随后凝固，从而产生增加承载力的效果。
