Pile-anchor integrated pile bottom post-grouting compression-resistant and pulling-resistant structure and construction method
The invention discloses a pile-anchor integrated pile-bottom post-grouting compression-resistant and pulling-resistant structure and a construction method of the pile-anchor integrated pile-bottom post-grouting compression-resistant and pulling-resistant structure. According to the compression-resistant and pulling-resistant structure, the piles are arranged on the upper soil layer section and can bear large compression-resistant loads and partial pulling-resistant loads, the pressure type anchor rods are arranged on the lower bedrock section, the anchor rods in the bedrock can provide high pulling-resistant force, and compression resistance and pulling resistance can be achieved through the pile-anchor integrated mode. According to the pile-anchor integrated pile bottom post-grouting compression-resistant and uplift structure, the compression-resistant and uplift bearing capacity of a single pile can be improved, the number of piles is reduced, and the construction cost of a pile foundation is saved.
本发明公开了一种桩锚一体桩底后注浆的抗压抗拔结构及施工方法。本发明提出的抗压抗拔结构在上部土层段为桩，可以承受较大的抗压荷载和部分抗拔荷载，而在下部基岩段为压力型锚杆，基岩中的锚杆能提供很高的抗拔力，桩锚一体的形式既能抗压又能抗拔。本发明的桩锚一体桩底后注浆的抗压抗拔结构可提高单桩抗压抗拔承载力，减少桩数，节约桩基造价。
