DISPOSAL METHOD DESIGN
在建筑物的南面采用小型挖机（PC60）修建一个临时施工通道至塌方土体上方，通道距离西面 挡土墙 3000mm，通道宽度为 2600mm。 （将上部不稳定的土体进行清除，然后采用挖机从土方 的上面开始将垮塌的土体移除，倒土至回填土区域，多余土方转至指定临时堆土位置，由多功 能挖机转走。） Set a temporary construction access to the top of collapsed area by small size excavator (PC60) on the south of the building. The access is 3000mm away from the retaining wall on the west with the width of 2600mm.(Remove the unstabel soil and excavate the collapsed soil from the top by excavator, pour the soil to backfilling area and transport the extra soil to appointed temporary soil pour site by multiple excavator). 第一层边坡开挖 1800mm 深，根据鲲池倒班宿舍地勘报告、地基基础设计规范 6.6.2 土质边坡坡 度允许值，坚硬粘土高度在 5 米内采用 1:0.75~1:1，本方案为确保安全采用 1:1，如图。 Excavate 1800mm deep of the first layer slopea; in accordance with the geographic report of Kunchi Living Quarter and the subgrade foundation design regulation 6.6.2--the allowabel value of soil sloping angle,we apply 1:0.75~1:1 in the gumbo area within 5m in height; as to ensure safety, we apply 1:1 in this method statement,illustrated on diagram.

然后用电风镐锤击； Then hammer with electrical pneumatic picks; 先用长 0.7-1.3mHRB335B16 钢筋一头穿入钻头，另一头套入电风镐套筒中，调整水平角度， 利用电风镐的震动压力，将其打入土中，直至钢筋尾部 10cm 左右； Pass one end of the 0.7-1.3m long HRB335B16 rebar through the anchor bit, put another end into the casing of electrical pneumatic picks; adjust the longtitude, pump it into soil till 10cm of the rebar end with the vibration of electrical pneumatic picks. 取出长 1.3m 的钢筋， 再换长 2.3m 钢筋插入已打入土中的钻头， 同样用电风镐将其打入土中， 直至钢筋尾部 10cm 左右，取出钢筋（钻头留在土体当中） ，成孔过程完成； Pull out the 1.3m long rebar, pump the 2.3m long rebar into the anchor bit with electrical pneumatic picks till 10cm of the rebar; pull out the rebar (leave the bit in soil), then the drilling process is done. 成孔后灌入素水泥浆（灌浆时应把灌浆机管头插至孔底，慢速灌至孔口，然后缓慢拔出灌浆 机管头） ，插入预先做好的锚杆，然后补灌部位未灌满的空洞，锚杆完成。 Pouring the neat cement into the holes (It should insert the tube head of grouting machine into hole bottom, slowly grout till the orifice and slowly pull it out); insert the prefabricated anchor rod and replenish the uncompleted hollow. 为进一步增强边坡稳定性，挂钢丝网，上铺设 60mm~80mm 细石混凝土保护。 Hang on the steel wire , pave 60mm~80mm fine stone concrete for protection. 护坡每清理 1.8m 高度的土体就做一次，第二层从反方向退后开挖。以保证土体不被地表水侵 蚀。边坡的角度采用自然边坡角度 45（1:1）。具体施工过程如下图所示。 Repeat the action mentioned above after clearance of every 1.8m in height. Excavate the second layer from the opposite direction. As to ensure the soil from damaging by surface water, the slope angle should be the natural slope angle 45(1:1).
