Foundation pit supporting pre-stressed anchor cable embedded pipe leakage prevention construction method
The invention discloses an anti-leakage construction method for a pre-stressed anchor cable embedded pipe of a foundation pit support. The method comprises the following steps that S10, secondary grouting is conducted on a pre-stressed anchor cable; s20, main reinforcements and stirrups of the top beam and the waist beam are bound; s30, a PVC protection sleeve is arranged in the pre-stressed anchor cable in a penetrating mode; s40, a crown beam PE grouting pipe is pre-buried in the PVC protective sleeve; s50, a waist beam PE grouting pipe is pre-buried in an anchor cable hole channel; s60, a crown beam anchor cable PVC protection sleeve head and a waist beam anchor cable hole opening are blocked; s70, concrete pouring and curing are conducted on the top beams and the waist beams; s80, the pre-stressed anchor cable is tensioned and locked; s90, whether the anchor head leakage phenomenon occurs or not after the anchor cable is tensioned and locked is judged; s100, epoxy resin is poured into a PE grouting pipe opening; s110, a PE grouting pipe opening is closed; the method has the beneficial effects that the method is convenient and fast to operate, quick leaking stoppage can be achieved, and the influence on site construction is reduced.
本发明公开了一种基坑支护预应力锚索预埋管防堵漏施工方法，该方法包括以下步骤:S10：对预应力锚索进行二次注浆；S20：对冠梁和腰梁的主筋以及箍筋进行绑扎；S30：在预应力锚索中穿入PVC保护套管；S40：将冠梁PE注浆管预埋至PVC保护套管内；S50：将腰梁PE注浆管预埋至锚索孔道内；S60：对冠梁锚索PVC保护套管头以及腰梁锚索孔口进行封堵；S70：对冠梁及腰梁进行混凝土浇筑及养护；S80：对预应力锚索张拉锁定；S90：判断锚索完成张拉和锁定后是否出现锚头渗漏现象；S100：在PE注浆管口处灌入环氧树脂；S110：封闭PE注浆管口；S120：完成堵漏，本发明的有益效果是：该方法操作便捷，能够快速堵漏，减少对现场施工的影响。
