本工程污水管道的接口設(shè)計考慮到本工程位于##區(qū)，管道易于沉降所以采用承插式柔性接口，以防管道不均勻沉降和提高管道的密封性能。承插式膠圈柔接口安裝時應(yīng)注意以下事項(xiàng)： </p> <p> ①安裝前應(yīng)徹底清潔接頭內(nèi)的表面、凹槽，止推圈和橡膠圈，應(yīng)確保其無油污灰塵 </p> <p> ②安裝密封圈時應(yīng)確保密封圈與凹槽、管壁均勻貼合，并在安裝前使用潤滑劑封圈。③填打膠圈出現(xiàn)“棉花”、嚇?biāo)颈恰?、“凹兜”、或“跳井”時，可利用鐵牙將接口間隙適當(dāng)撐大，進(jìn)行調(diào)整處理。④鏨子應(yīng)貼插口壁按由下向上的順序打，使膠圈沿一個方向依次均勻入承口水線。填膠圈的質(zhì)量標(biāo)準(zhǔn)：膠圈壓縮率符合要求；膠圈填至無小臺承口外緣距離均勻；無“麻花”、“悶鼻”、“曰兕”、“跳井”現(xiàn)象本工程檢查井分為雨水檢查井和污水檢查井，檢查井均采用方形檢查井，均采用磚砌。鑫環(huán)球廠家球墨鑄鐵管國標(biāo)。桂林鑄鐵管廠家</p><p

預(yù)防和控制措施是：1、改進(jìn)離心設(shè)備，有效預(yù)防裂紋 </p> <p> 減少鐵液在高溫的停留時間，加強(qiáng)孕育特別是隨流孕育效果。隨流孕育劑加入量控制為鐵液量的0.1-0.25%;確保管模粉分布均勻，控制管模內(nèi)表面用量為20-30g/m2?？刂坪盟浣饘傩碗x心機(jī)冶煉工藝參數(shù)。 </p> <p> 離心機(jī)要防止流槽振動造成鐵液濺出現(xiàn)象，承口砂芯要安放合適，避免產(chǎn)生毛刺。控制鐵液成分，降低鐵液的含硅量，沖入球化劑后W(Si)應(yīng)控制在0.8-1.2%為宜。離心機(jī)機(jī)殼內(nèi)采用均勻布置圓弧形噴淋冷卻管，且分段設(shè)置，并避免各段的冷卻水相互影響。玉林鴻輝鑄管廠家電話</p><p
