Construction method for slope supporting and reinforcing
The invention relates to a construction method for slope supporting and reinforcing. The construction method comprises the steps of excavating a foundation pit, and performing slope arrangement; drilling; manufacturing spiral grouting floral tubes, specifically, taking spiral ribs and the grouting floral tubes, forming a plurality of grout outlets in the grouting floral tubes, inserting the grouting floral tubes into the spiral ribs, enabling the grouting floral tubes and the spiral ribs to be connected and fixed through inner and outer cross ribs, and enabling the outer cross ribs to extend out of the spiral ribs; driving the spiral grouting floral tubes into the drilled holes, anchoring the bottom ends of the spiral grouting floral tubes into a soil layer at the bottom of the holes, andenabling the outer cross ribs to be located outside the drilled holes; grouting the spiral grouting floral tubes in two times; spraying concrete to the slope surface, paving a reinforcing mesh on theslope surface before final setting of the concrete, and enabling the reinforcing mesh to be fixedly connected with outer cross ribs; and spraying the concrete onto the slope concrete paved with the reinforcing mesh for the second time. The spiral ribs are combined with the grouting floral tubes, the spiral grouting floral tubes, the concrete spraying layer and the side slope form a combined actionsystem through grouting, secondary spraying and anchoring and the like, and loosening and separation of the soft soil side slope are prevented.
本发明涉及一种边坡支护加固的施工方法，包括：基坑开挖和边坡整理；钻孔；制作螺旋注浆花管：取螺旋筋和注浆花管，在注浆花管上开设多个出浆孔，将注浆花管插入到螺旋筋中，并通过内外十字筋将两者连接固定且所述外部十字筋伸出至所述螺旋筋外；将螺旋注浆花管打入至钻孔内，螺旋注浆花管的底端锚入至孔底土层中且外部十字筋位于钻孔外；对螺旋注浆花管分两次完成注浆；对坡面喷射混凝土，在混凝土终凝前在上铺设钢筋网，钢筋网与外部十字筋固连；在铺设有钢筋网的坡面混凝土上进行第二次喷射混凝土。本发明将螺旋筋与注浆花管结合，通过注浆、二次喷锚等，使螺旋注浆花管、混凝土喷层和边坡形成共同作用的体系，防止软土边坡松动分离。
