水下工作原理

1、潛水信號繩(sheng)掌控。潛水信繩(sheng)員是水下潛人(ren)員的主要人(ren)，必須準確收(shou)、發潛水應急信號。

2、下(xia)(xia)潛前(qian)，在組長下(xia)(xia)，對潛水裝(zhuang)備(bei)和器材進行檢查和，為(wei)下(xia)(xia)潛人員著裝(zhuang)和上來時候的卸裝(zhuang)。

3、當下(xia)潛(qian)(qian)人員入(ru)水至頭盔剛要淹沒時(shi)，拉住下(xia)潛(qian)(qian)人員并檢查(cha)潛(qian)(qian)水裝具(ju)是(shi)否水密，確認(ren)完好后，通知(zhi)下(xia)潛(qian)(qian)人員下(xia)潛(qian)(qian)，下(xia)潛(qian)(qian)深度，并及(ji)時(shi)報告。

4、作業時(shi)(shi)精力集中，認真負(fu)責，堅(jian)守崗位。暫時(shi)(shi)離(li)崗必須經組(zu)長同意，并(bing)通知下潛人員。

5、收發潛(qian)(qian)水(shui)(shui)信號應(ying)清(qing)楚、正(zheng)確(que)。潛(qian)(qian)水(shui)(shui)電話(hua)時(shi)，要(yao)時(shi)刻詢問水(shui)(shui)下(xia)工作情(qing)況和環境，潛(qian)(qian)水(shui)(shui)人員的(de)潛(qian)(qian)水(shui)(shui)感覺要(yao)時(shi)刻保(bao)持較高意識(shi)。

6、經常觀察下潛(qian)人員的氣泡及其行動方向。

7、根據下(xia)潛(qian)人(ren)員的要求(qiu)，適當收緊和放松信號(hao)繩(sheng)。傳(chuan)送物品后及(ji)時收回(hui)多余(yu)的部分(fen)。隨時清理信號(hao)繩(sheng)，防止絞纏，如已(yi)絞纏及(ji)時向組長報告，并協(xie)助下(xia)潛(qian)人(ren)員解脫。

8、遇(yu)有用(yong)信號或電(dian)話連續詢(xun)問而未下潛人員(yuan)回(hui)答，應立即但不是過(guo)快地將其(qi)拉面，同時向(xiang)報告(gao)。

水下切割工程主要有水下切割鋼筋籠、污水管道水下封堵、水下切割鋼管樁、水下切割變形護筒、水下切割灌注樁、水下切割沉船等。
1.每班潛水作業班組，工程負責人都指定電話員，信號員，應急潛水員，各崗位人員認真負責應急潛水員當備裝待命潛水。發現水下潛水員異常時，應立即水下救人。
2.每次潛水員下水前召開一次班前會議，主要就有關潛水。如何施工工作進行徹底交底到每人。
3.潛水員感冒等身體不舒服時，堅決不許潛水工作。
4.潛水員下水時，遇到與原來估計或上一班潛水員提供的工作環境信息不相符的情況，應立即與水面岸上電話員溝通匯報，果斷處理。如影響施工時，可中斷該次潛水，直至把危險情況排除，方可繼續下水作業。
5.潛水(shui)員在水(shui)中發生事故(gu)，應(ying)立即搶(qiang)救(jiu)(jiu)(jiu)出水(shui)，采取(qu)適當的急(ji)救(jiu)(jiu)(jiu)辦(ban)法施救(jiu)(jiu)(jiu)，同時撥打120，視(shi)情況送附(fu)近醫院治療施救(jiu)(jiu)(jiu)。
