工程概況新橋河綜合整治工程整治范圍為上游起點(diǎn)為長(zhǎng)流陂水庫(kù)溢洪道已整治段末端，下游終點(diǎn)為崗頭調(diào)節(jié)池，治理河段長(zhǎng)約 。工程治理內(nèi)容主要包括河道防洪達(dá)標(biāo)治理、河道沿線截污完善工程、河道生態(tài)補(bǔ)水工程、生態(tài)修復(fù)工程（沿河綠化）以及河道附屬設(shè)施等 5 方面。 截污完善工程頂管工程新橋河綜合整治工程截污完善工程截污管沿河底兩側(cè)敷設(shè)， 107 國(guó)道箱涵位置采用頂管形式穿越 107 國(guó)道，分布在新橋河 107 國(guó)道箱涵兩岸，管材 III 級(jí)鋼筋混凝土頂管專用管（F 型鋼套環(huán)接口） 。左岸從工作井 JW55 至接收井 JW54 為 DN1200，長(zhǎng)度 144m，坡度%；從工作井 JW55 至接收井 JW57 為 DN1200，長(zhǎng)度 74m，坡度 %。右岸從工作
