Steel flower tube construction method for soft slope
The invention relates to the technical field of anchor rod construction, and discloses a steel flower tube construction method for a soft slope. The method comprises the steps that before construction, the side slope is trimmed first, and the hole positioning is facilitated; a steel flower tube is then machined, and a plurality of grouting holes arranged at intervals are arranged on the steel flower tube; after the steel flower tube is machined, the steel flower tube is aligned to a hole, and the steel flower tube is directly hammering to the soil layer by using an air hammer until the steel flower tube reaches a set depth; and high-pressure grouting is carried out twice in succession, during grouting, cement slurry is injected into the soil layer from each grouting hole in the case of high-pressure injection, and the soil layer and the steel flower tube are connected into a whole. Before the initial setting of the first high-pressure injected cement slurry, secondary high-pressure grouting is carried out, and the soil layer and the steel flower tube are further reinforced, so that the soil layer and the steel flower tube are connected more stably, and the supporting effect is better.
本发明涉及锚杆施工的技术领域，公开了软弱边坡钢花管施工方法，施工前，先修整边坡，便于孔位定位，然后对钢花管进行加工，在钢花管上设置多个间隔布置的注浆孔，钢花管加工完成后，将钢花管对准孔位，使用空气锤直接将钢花管锤击至土层，并使钢花管直达设定深度，然后先后进行两次高压注浆，注浆时水泥浆液在高压注入的情况下，从各个注浆孔中喷射至土层，将土层与钢花管连成整体，在第一次高压注入的水泥浆液初凝前，进行第二次高压注浆，对土层与钢花管做进一步加固，使土层与钢花管连接更稳固，使支护效果更好。
