style="font-size:24px;">土工膜</span></strong></a>焊接必須注意一下幾點：</span><br /> <span style="line-height:2.5;font-family:Microsoft YaHei;font-size:18px;"> 1.焊膜時不許壓出死折，鋪設HDPE土工膜時，根據當地氣溫變化幅度和HDPE土工膜性能要求，預留出溫度變化引起的伸縮變形量；</span><br /> <span style="line-height:2.5;font-family:Microsoft YaHei;font-size:18px;"> 2.當手提焊機的溫度控制所指示的焊機溫度低于200℃時，要用干凈的布或棉紗撣掉再焊，必要時應重新打磨，切忌用手擦試；</span><br /> <span style="line-height:2.5;font-family:Microsoft YaHei;font-size:18px;"> 3.當接縫處有結露、潮濕、泥沙等影響時，處理后再進行焊接；</span><br /> <span style="line-height:2.5;font-family:Microsoft YaHei;font-size:18px;"> 4.在下雨期間或接縫有潮氣、露水、或者大沙的情況下不能進行焊接，但采取防護措施是除外；</span><br /> <span style="line-height:2.5;font-family:Microsoft YaHei;font-size:18px;"> 5.溫度低于5℃時，按照規范要求不應施工，如果必須施工的話，焊接前應對焊機進行預熱處理；</span><br /> <span style="line-height:2.5;font-family:Microsoft YaHei;font-size:18px;"> 6.擠壓焊接機在焊接過程中，應該經常檢查槍頭的滑塊，磨損較嚴重時應及時更換滑塊，以免損傷膜面；</span><br /> <span style="line-height:2.5;font-family:Microsoft YaHei;font-size:18px;"> 7.土工膜在焊接時應該采用穩壓性能好的發電機供電，在特殊情況下采用當地用電時，必須使用穩壓器，焊縫要求整齊、美觀、不得有滑焊、跳走現象；</span><br /> <span style="line-height:2.5;font-family:Microsoft YaHei;font-size:18px;"> 8.在遇上土工膜長度不夠時，需要長向拼接，應先把橫向焊縫焊好，再焊縱縫，橫向焊縫相距大于50cm應成T字型，不得十字交叉；</span><br /> <span style="line-height:2.5;font-family:Microsoft YaHei;font-size:18px;"> 9.相鄰土工膜焊縫應盡量錯縫搭接，膜塊間形成的結點，應為T字型，盡量減少十字型，縱模向焊縫交點處應用擠壓焊機加強。</span> </p> <p> <span style="line-height:2.5;font-family:Microsoft YaHei;font-size:18px;">
