Method for repairing pavement by reinforcing roadbed through grouting
The invention discloses a method for repairing a pavement by reinforcing a roadbed through grouting. The method comprises the following steps that the grouting position is determined; drilling is carried out according to the designed vacancy; slurry pouring is carried out; hole finishing is carried out; transferring to a next hole site for construction is carried out, wherein an interlaced jump grouting method is adopted for construction in order to avoid influences on peripheral existing hole sites; after grouting construction is finished, curing is conducted for 5 days, and then qualification detection is conducted; after the roadbed reinforced through grouting is detected to be qualified, C20 plain concrete with the thickness of 30 cm is poured into a C20 road groove; after the C20 plain concrete is cured to reach the strength of 70% or above, an emulsified asphalt viscous oil layer is spread; asphalt concrete is paved; a rubber asphalt stress absorption layer is paved; and after aqualified treatment area and other areas which do not need to be treated are milled and planed, a fine-grained AC-13 and SBS asphalt concrete upper surface layer is finally paved together. By means ofthe scheme, the old and stubborn problem of long-term pavement subsidence at local positions of a road can be effectively solved.
本发明公开了一种采用灌浆加固路基修复路面的方法,包括以下步骤:灌浆位置的确定;按设计空位进行钻孔;灌注浆液;终孔;转入下一孔位施工,为了不影响周边既成孔位,采用隔行跳打注浆法进行施工;压浆施工结束后,养生5天,然后进行合格性检测;注浆加固的路基检测合格后,在C20路槽内浇筑30cm厚C20素砼;在C20素砼养护至70%以上强度后,洒铺乳化沥青粘油层;铺筑沥青砼;铺设橡胶沥青应力吸收层;处治合格的区域与其他不需要处治的区域铣刨后,最后一起铺筑细粒式AC‑13、SBS沥青混凝土上面层。本方案能有效解决道路局部位置长期路面下沉的老顽疾。
