22、6m)。因沟槽北侧为居民楼房,原方案采用沟槽北侧锚喷支护,开挖坡度为1:0.4;沟槽南侧采用大开挖方式,从顶端按1:1.25坡度开挖至4米位置,留10米台阶,然后按1:1.25坡度放坡挖至基坑底。现阶段沟槽开挖施工已完成过半,西侧已挖深至6m,东侧已挖深至4m。已挖完的沟槽北侧边坡锚喷支护已完成,但因土体稳定性较差,且东侧与支护结构终点的土体出现塌方,造成北侧边坡锚喷支护结构下沉,对锚喷支护结构造成了破坏。原锚喷支护结构无法满足施工的需要经现场勘查后决定将原护壁以北1m土方采用1:0.624坡度人工取土取出,并随取土随凿除原护壁钢筋混凝土。人工取土时每次取土深度不大于0.7m,长度不大于5.0
23、m,严禁超挖,随取土随进行锚喷支护。沟槽北侧重新施作锚喷护壁,护壁采用25土钉锚杆+6网片+喷射C25混凝土结构形式进行支护。锚喷混凝土厚度为15cm,锚杆长度为5.0m。 为保证锚喷结构整体的稳定性及楼房地基安全,楼房处10m长锚喷护壁将设置地锚,将护壁连接筋与 2m长42钢管(壁厚3.25mm)地锚焊接连接。地锚需锚入原楼房地梁或混凝土地面内。沟槽西侧端头靠近竖井位置处开挖坡度同沟槽一致,随开挖对裸漏土壤部位进行锚喷支护。因沟槽北侧放坡系数为1:0.624,与我单位施工段所接沟槽处放坡系数需大于1:0.9,如若不能满足,为保证施工安全建议护壁长度延伸10m。二、主要工程数量(未延伸10m)
