Grouting method for side slope supporting and reinforcing method for side slope drainage ditch
The invention discloses a grouting method for side slope supporting and a reinforcing method of a side slope drainage ditch. The grouting method comprises the following steps that grouting holes are formed in a side slope; and grout is injected into the grouting holes, grouting is carried out in a segmented manner, after grouting is completed every time, the grout in the grouting holes is extruded till the grout permeates out of the grouting holes and forms splitting permeation on a soil body, grouting continues after standing is carried out for a period of time, and the process is repeated till grouting of the grouting holes is completed. By means of the grouting method, segmented grouting is conducted on the grouting holes, the grout is extruded to enable the grout to permeate out of the side walls of the grouting holes and enter the soil body to form splitting, and therefore the resistance to the permeation effect of water flow on the side slope is improved; and in addition, multiple times of grouting and extruding can form multi-layer splitting, water permeating into the soil body of the side slope is blocked layer by layer, and therefore the problems of side slope landslide and water and soil loss caused by the fact that the water permeates into a side slope base are avoided.
本发明公开了一种边坡支护的注浆方法及其边坡排水沟的加固方法，包括以下步骤；在边坡上开设注浆孔；向所述注浆孔中注入浆液，注浆分段进行，每次注浆完毕后，对所述注浆孔内的浆液挤压，直至所述浆液渗透出所述注浆孔并对土体形成劈裂渗透，静置一段时间后继续注浆，如此往复，直至所述注浆孔注浆完毕；本发明通过对注浆孔分段注浆，并分别对浆液进行挤压使注浆孔的侧壁渗透出浆液并进入到土体中形成劈裂，从而增加对边坡上水流渗透作用的抵抗能力，此外，多次的注浆并挤压，会形成多层的劈裂，对于渗透进入边坡土体的水分进行层层阻隔，避免了水分渗入到边坡基底，造成边坡滑坡和水土流失的问题。
