加长臂挖掘机进行楼顶作业。高楼顶端惊现挖掘机挖斗，The top of the tall building, excavator bucket
8日下午4时许，记者来到渝中区华一坡原科技情报所办公楼所在地。本来12层楼的房屋，现在已拆除两层，还有10层，三大幢构成一个“Y”字型的整体房子，楼房四周堆满了砖石，此处除此楼外，周边没有与其相等高的楼或山坡。记者从铺满砖石的楼梯，攀着裸露的钢筋，半跪半爬来到楼顶。约800平方米的楼顶，已被挖去400平方米，一辆橙色挖掘机停放在尚未挖除的半边楼顶上。挖掘机的前端安装着钻头，前方1米远的地方有一个直径为7厘米大的窟窿，在它的左前侧3米远的地方则放着它的挖掘斗。
8 days afternoon 4 when Xu, reporters came to the Yuzhong District Huayi Po original information technology office are located. Originally, 12 floors of the house, now demolished the two layer, and the 10 layer, three buildings constitute the whole house is a "Y" - shaped, around buildings with masonry, in addition to the building here, not equal to around high buildings or hills. Reporters from the covered with masonry staircase, climb bare steel, half kneeling half climb to the roof. About 800 square meters of the roof, has been dug to 400 square meters, an orange excavator Park in has not been excavated half of the roof. Excavator mounted at the front of the drill bit, 1 meters in front of a diameter of 7 cm large hole, at the front left it 3 meters away is placed the excavating bucket.

挖掘机是这样上楼的：首先由工人顺着楼梯，将一台重约5吨的卷压机抬到楼顶；然后，将卷压机固定在楼顶边缘；最后，伸出起重杆，放下钢绳，把重22吨的挖掘机绑在上面，通过卷压机，把它慢慢吊上楼顶。“这是我们首创的楼顶挖掘机，往下挖更安全和便捷。”施工队负责人赵某说，这是他们第二次使用这种方式。以前用这种方式拆除了21层的西南大酒店，都没有事。他介绍，只要挖掘机都在主梁上行驶，不开到预制板上面，就十分安全
Excavator is upstairs: first by the workers down the stairs, will roll press to lift a weight of about 5 tons to the roof; and then, the volume compressor fixed on the edge; finally, out of the lifting rod, put down the rope, the excavator 22 ton tied at the top, the roll press, take it slowly. On the roof. "This is the roof of excavator we first, dig more safe and convenient." The construction team leader Zhao said, this is the second time they use this way. Before using this way to dismantle 21 layers of Southwest Le Grand Large Hotel, are not. He introduced, as long as the excavator are running on the main, not to the prefabricated plate, it is very safe
施工方称楼摇才安全
The construction side said the floor shake was safe
“加长臂在楼顶开来开去，但都在主梁上开，一旦开到预制板上，肯定要掉下去。”一名姓张的工人告诉记者，挖掘机用钻头先是在楼顶凿出无数个洞后，再换上旁边的挖掘斗将土石挖开。他说，他和其他工人就是在挖掘机油缸凿出洞子后，负责清理洞里的残渣和周围的一些钢筋，方便挖掘机进一步的挖掘工作。“房子都是从上往下进行拆除，我们决定将挖掘机开到楼顶上进行作业。”施工队负责人赵某说，挖掘机作业的时候会发出震天的轰鸣，而且钻头钻钢筋梁时，楼房都会左右摇摆，阵势比地震还厉害。“楼房摇摆，才说明楼房结构安全。”
"The arms at the top of the building around, but on the main drive, once to the prefabricated plate, must fall." A worker named Zhang told reporters, excavator drill first countless a hole in the roof cut, mining and then replaced the next bucket will rock digging. He said, he and other workers in the excavator cylinder cut hole, responsible for some steel cleaning hole residues and surrounding, convenient for further mining excavator. "The house is down from the dismantled, we decided to the excavator operation." The construction team leader Zhao said, when the excavator will be issued deafening roar, and the reinforced beam drill, the building will swing around, was worse than the earthquake. "Building sway, only that the structural safety of buildings."
