Construction method adopting slope concrete crack repairing device
The invention discloses a construction method adopting a side slope concrete crack repairing device.The repairing device comprises a pile casing and a fixed support, the fixed support is fixed to a side slope soil body, and the pile casing and the fixed support are detachably connected.The construction method comprises the steps that after soil nails are arranged, the repairing devices are arranged between the soil nails at intervals, and the repairing devices are arranged at intervals; the construction method comprises the following steps: paving a reinforcing mesh, stably binding the reinforcing mesh with soil nails and repairing devices, performing sprayed concrete layer construction, opening the repairing devices on two sides of a crack after the sprayed concrete layer is separated from a soil layer for a period of time and a through crack appears, performing reinforced soil nail construction, and performing grouting. According to the repairing device, an effective means for judging the void condition can be provided when a large through crack occurs in a common soil nail spraying slope, secondary reinforcement can be carried out under the condition that an original concrete layer does not need to be broken and dismantled, the repairing difficulty of the slope of this kind is greatly reduced, the repairing device is extremely low in cost, and the repairing effect is good. And the cost of the soil nail slope protection is hardly increased.
本发明公开了一种采用边坡混凝土裂缝修补装置的施工方法，所述修补装置包括护筒和固定支座，所述固定支座与边坡土体固定，所述护筒和所述固定支座可拆卸连接，其施工方法包括在设置土钉后，在土钉之间间隔安设修补装置，铺设钢筋网片并将其与土钉和修补装置绑扎稳固后进行喷射混凝土层施工，当喷射混凝土层经过一段时间与土层脱空后出现贯通裂缝后，打开裂缝两边的修补装置，进行补强土钉施工并进行灌浆，本发明的修补装置可以在普通土钉喷坡出现大型贯通裂缝时提供有效的判断脱空情况的手段，且可以在不用破拆原混凝土层的情况下进行二次补强，大幅度减小此类边坡的修复难度，本发明中修补装置成本极低，几乎不增加该类土钉护坡的成本。
