水下施工人員要求：水下作業(yè)潛水員應(yīng)持有潛水員證、健康證和潛水作業(yè)個人記錄簿，潛水監(jiān)督應(yīng)持有潛水監(jiān)督證，生命支持員應(yīng)持有生命支持員證。從事海上作業(yè)的人員應(yīng)持有海上作業(yè)安全救生證，從事無損檢測的潛水員應(yīng)持有無損檢測證，從事水下焊接作業(yè)的人員應(yīng)持有水下焊接證，其他水下作業(yè)（如高壓水槍等）的人員應(yīng)持有相關(guān)的證書。為了克服壓力的障礙，進(jìn)行空氣增壓以平衡水的靜壓，實(shí)現(xiàn)在更深的水中使人能長時間作業(yè)的環(huán)境，五河防洪排澇清淤清障。無論何種類型潛水裝具，作業(yè)人員肺部氣壓都必須非常接近周圍環(huán)境中氣壓。<br/>

這使得泥漿在堆場中沉積速度非常緩慢，固結(jié)時間很長。吹淤后的淤泥堆場在落淤后的兩三年時間內(nèi)只能在表面形成20cm左右厚的天然硬殼層，而下部仍然為流態(tài)的淤泥，含水率仍在，進(jìn)行普通的地基處理難度很大［13］。堆場表層處理技術(shù)則是利用淤泥堆場原位固化處理技術(shù)(圖4)，人為地在淤泥堆場表面快速形成一層人工硬殼層，人工硬殼層具有一定的強(qiáng)度和剛度，滿足小型機(jī)械的施工要求，可以進(jìn)行排水板鋪設(shè)和堆載施工，從而方便對堆場進(jìn)一步的處理。人工硬殼層的設(shè)計是表層處理技術(shù)的關(guān)鍵，主要考慮后續(xù)施工的要求，結(jié)合下部淤泥的性質(zhì)，通過試驗(yàn)和模擬確定硬殼層的強(qiáng)度參數(shù)和設(shè)計。在本項(xiàng)目中選擇合適的河段采用生態(tài)清淤的方式。帶水作業(yè)，無需排水就可以去除河底沉積物質(zhì)不會影響河岸邊水生態(tài)環(huán)境和生物種群通過水泵沿河底抽吸，不會產(chǎn)生渾濁液體，對河流水體和周圍環(huán)境不會產(chǎn)生負(fù)面影響通過這一處理工藝，可在很難靠近的區(qū)域進(jìn)行清淤。通過聲納測試，還可對有些區(qū)域按等級優(yōu)先進(jìn)行清淤工作。不需要淤泥沉淀區(qū)域，不需要污泥中間儲存池，也不需要鋪設(shè)臨時卡車運(yùn)輸通道被處置污泥體積大幅下降。由于柵條是一個整體，雖然各柵條由連桿和套管（或肋片和槽口）橫向固定.五河水池池底清淤清污</p><p

（5）當(dāng)水下焊接工作點(diǎn)的水流速度超過0.1至0.3m/s且風(fēng)速超過6級時，禁止水下焊接作業(yè)。<br/> 2.水下焊接預(yù)防電擊安全措施<br/> （1）一旦形成水下電弧，周圍的水就會蒸發(fā)，形成空腔或氣泡。從操作安全的角度來看，水下焊接電源必須是直流電，禁止交流電源。<br/> （2）水下焊接設(shè)備和電源應(yīng)具有良好的絕緣和防水性能。并應(yīng)具有耐鹽霧腐蝕，耐大氣腐蝕和耐海水腐蝕的能力。<br/> （3）水下焊接電焊機(jī)必須接地，接地線應(yīng)拋光，以防止腐蝕。<br/> （4）電路控制系統(tǒng)應(yīng)安裝水下干式或部分干式焊接，事故報警系統(tǒng)和停電系統(tǒng)。<br/> （5）在水下焊接時，通常需要更換電極。在水下更換電極時，必須首先發(fā)出拉動信號，以確認(rèn)電路已被切斷，否則，很容易引起電擊和危險。<br/> 五河防洪排澇清淤清障</p><p
