泥水工安全技术交底

一、砌体施工：
 ⒈挖掘土方，两人操作间距保持2~3m，并由上而下逐层挖掘，禁止采取掏洞的操作方法。
 ⒉开挖沟槽、基坑等，应根据土质和现场施工员交底放坡，挖出的泥土应堆放在坑槽边1m以外，堆高不得超过1.5m。

 ⒊砌基础时，应检查和经常注意基坑土质变化情况，有无崩裂现象。堆放材料应离开坑槽边1m以上。当基坑较须设护壁支撑时，操作人员应设梯子上下，不得攀跳，运料不得碰撞支撑。

 ⒋墙身砌体高度超过1.2m时，应搭设脚手架。在一层以上或高度超过4m时采用里脚手架必须在墙外张挂安全网，采用外脚手架应绑护身栏杆后方准操作。

 ⒌用内架砌外墙时，架板要低于外墙20cm，墙外按规定张挂安全网。
 ⒍脚手架上堆砖不得超过三皮，架子转角处不得堆砧，除操作层外，上下皮架只允许堆零星材料，不得多层都堆料。

 ⒎在高处砌墙时，转砧应面向墙面，工作完毕应将脚手板和砖墙上的碎砖，灰浆清扫干净，防止掉落伤

1, Masonry Construction:
 ⒈ excavation of earth to keep distance between the two operations 2 ~ 3m, and top-down floor by floor mining, prohibit the operation method to dig holes.
 ⒉ trench excavation, foundation, etc., should be based on soil and site construction workers clarification at Slope, excavated soil should be stacked outside the pit side of 1m, forklifts must not exceed 1.5m.

 ⒊ puzzle base, the foundation should be checked and regular attention to soil changes, with or without crack phenomenon. Stacking materials, leave the pit side for more than 1m. When the pit wall protection shall be provided more support, the operator should set the ladder up and down, not climbing jump, transport material may not impact support.

 ⒋ masonry wall height of more than 1.2m should scaffold erection. In the layer above or more than 4m high scaffold to be used in wall hung safety nets, scaffolding should be tied to protect oneself by external standards operate behind bars.

 ⒌ with the external walls and inside the frame, the frame is lower than the wall plate 20cm, wall display in accordance with the provisions of the safety net.
 ⒍ scaffold shall not exceed three skin brick heap, not stack anvil corner shelf, in addition to operating level, the upper and lower frame allows only heap sporadic skin material, not multi-piled material.

 ⒎ the high walls, the switch should be oriented anvil wall, should be completed working on the scaffold board and brick walls broken brick, mortar cleaned to prevent falling injuries
