泥水工安全技術(shù)交底
一、砌體施工：
⒈挖掘土方，兩人操作間距保持2~3m，并由上而下逐層挖掘，禁止采取掏洞的操作方法。
⒉開挖溝槽、基坑等，應(yīng)根據(jù)土質(zhì)和現(xiàn)場施工員交底放坡，挖出的泥土應(yīng)堆放在坑槽邊1m以外，堆高不得超過1.5m。
⒊砌基礎(chǔ)時(shí)，應(yīng)檢查和經(jīng)常注意基坑土質(zhì)變化情況，有無崩裂現(xiàn)象。堆放材料應(yīng)離開坑槽邊1m以上。當(dāng)基坑較須設(shè)護(hù)壁支撐時(shí)，操作人員應(yīng)設(shè)梯子上下，不得攀跳，運(yùn)料不得碰撞支撐。
⒋墻身砌體高度超過1.2m時(shí)，應(yīng)搭設(shè)腳手架。在一層以上或高度超過4m時(shí)采用里腳手架必須在墻外張掛安全網(wǎng)，采用外腳手架應(yīng)綁護(hù)身欄桿后方準(zhǔn)操作。
⒌用內(nèi)架砌外墻時(shí)，架板要低于外墻20cm，墻外按規(guī)定張掛安全網(wǎng)。
⒍腳手架上堆磚不得超過三皮，架子轉(zhuǎn)角處不得堆砧，除操作層外，上下皮架只允許堆零星材料，不得多層都堆料。
⒎在高處砌墻時(shí)，轉(zhuǎn)砧應(yīng)面向墻面，工作完畢應(yīng)將腳手板和磚墻上的碎磚，灰漿清掃干凈，防止掉落傷

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
