Construction method for pressure-bearing anti-floating anchor of saturated-water silt-sand stratum
The invention belongs to the technical field of anti-floating anchors and discloses a construction method for a pressure-bearing anti-floating anchor of a saturated-water silt-sand stratum in order tosolve the problem that collapse can be generated easily when pore formation is conducted on the saturated-water silt-sand stratum and quality of the anti-floating anchor cannot be guaranteed. The construction method for the pressure-bearing anti-floating anchor of the saturated-water silt-sand stratum has the beneficial effects that cement stirring or high-pressure spiral spraying is conducted atfirst for solidification of the stratum and then hole formation, placement of a reinforcement cage and casting are conducted in succession, so that construction of the anti-floating anchor of the saturated-water silt-sand stratum is completed, and quality of the anti-floating anchor is guaranteed; and the problem in the prior art that hole collapse can be easily generated when the hole formationis conducted during construction of the anti-floating anchor on the saturated-water silt-sand stratum is solved.
本发明属于抗浮锚杆技术领域，公开了一种饱水粉砂地层承压型抗浮锚杆施工方法，为了解决在饱水粉砂地层成孔容易垮塌而无法保证抗浮锚杆质量的问题。本发明的饱水粉砂地层承压型抗浮锚杆施工方法，先进行水泥搅拌或高压旋喷对地层进行固结，然后再依次成孔、放入钢筋笼和注浆，从而完成饱和水粉砂地层抗浮锚杆的施工，保证抗浮锚杆的质量；解决了现有技术在饱水粉砂地层施工抗浮锚杆时成孔过程中容易跨孔的问题。
