聲(sheng)(sheng)測(ce)管可(ke)直接用點焊或鐵絲綁扎(zha)的方法固定(ding)(ding)在(zai)(zai)鋼筋(jin)籠內側(ce)上，固定(ding)(ding)點的間距一般不超過2 m，其中聲(sheng)(sheng)測(ce)管底(di)端和接頭(tou)部位宜設固定(ding)(ding)點。對(dui)于無(wu)鋼筋(jin)籠的部位，聲(sheng)(sheng)測(ce)管可(ke)用鋼筋(jin)支架固定(ding)(ding)。為了保證(zheng)聲(sheng)(sheng)測(ce)管的相互平行(xing)，可(ke)以在(zai)(zai)聲(sheng)(sheng)測(ce)管間點焊三角(jiao)形鋼筋(jin)架支撐(cheng)。

　　聲測管(guan)的安裝準備(bei)工作

　　(1) 安裝前(qian)工作：檢查聲(sheng)測管底(di)部基(ji)礎平(ping)整度、水平(ping)、標(biao)高;核對土建基(ji)準(zhun)，確定涵(han)洞位置、中心軸線、中點。

　　(2) 連接安(an)裝(zhuang)(zhuang)(zhuang)聲測管(guan)(guan)(guan)：根(gen)據(ju)涵洞實際情(qing)況，排(pai)放(fang)(fang)涵管(guan)(guan)(guan)。如果涵洞兩(liang)(liang)側(ce)(ce)進(jin)出(chu)水口是與路(lu)基同(tong)坡度(du)的(de)(de)斜口形式，安(an)裝(zhuang)(zhuang)(zhuang)時先(xian)安(an)裝(zhuang)(zhuang)(zhuang)中(zhong)(zhong)(zhong)間(jian)(jian)(jian)管(guan)(guan)(guan)節(jie)(jie)，在基礎(chu)長度(du)方向留出(chu)進(jin)出(chu)水口的(de)(de)位置。中(zhong)(zhong)(zhong)間(jian)(jian)(jian)管(guan)(guan)(guan)節(jie)(jie)全部安(an)裝(zhuang)(zhuang)(zhuang)完畢，校正就位后再安(an)裝(zhuang)(zhuang)(zhuang)兩(liang)(liang)側(ce)(ce)進(jin)出(chu)水口。安(an)裝(zhuang)(zhuang)(zhuang)時從(cong)一(yi)側(ce)(ce)排(pai)放(fang)(fang)根(gen)管(guan)(guan)(guan)節(jie)(jie)，使其(qi)(qi)管(guan)(guan)(guan)子(zi)中(zhong)(zhong)(zhong)心和基礎(chu)縱向中(zhong)(zhong)(zhong)心線(xian)平(ping)行，同(tong)樣把第(di)二根(gen)管(guan)(guan)(guan)放(fang)(fang)置就位，當兩(liang)(liang)根(gen)管(guan)(guan)(guan)相鄰(lin)法(fa)(fa)蘭間(jian)(jian)(jian)相距3—5cm的(de)(de)縫隙時，用(yong)小撬(qiao)(qiao)棍對準(zhun)法(fa)(fa)蘭上的(de)(de)螺(luo)栓孔，使其(qi)(qi)兩(liang)(liang)根(gen)管(guan)(guan)(guan)法(fa)(fa)蘭上的(de)(de)螺(luo)栓孔對正，這時從(cong)第(di)二節(jie)(jie)管(guan)(guan)(guan)的(de)(de)另一(yi)端(duan)用(yong)撬(qiao)(qiao)杠撬(qiao)(qiao)動管(guan)(guan)(guan)節(jie)(jie)，使其(qi)(qi)縱向平(ping)移，使兩(liang)(liang)法(fa)(fa)蘭間(jian)(jian)(jian)距在2cm左(zuo)右，然后全部穿上螺(luo)栓，擰上螺(luo)絲，帶平(ping)扣(kou)即可(ke)。此后依此方式逐節(jie)(jie)依次連接，每道涵洞中(zhong)(zhong)(zhong)間(jian)(jian)(jian)管(guan)(guan)(guan)節(jie)(jie)無先(xian)后次序，可(ke)以隨意(yi)連接。

　　(3) 聲測管(guan)鑲(xiang)石(shi)棉(mian)(mian)墊(dian)(dian)：由(you)于(yu)現(xian)場地勢(shi)等原因，有時(shi)相(xiang)鄰兩法(fa)蘭(lan)(lan)之(zhi)(zhi)間(jian)間(jian)距較(jiao)小(xiao)，這時(shi)用手錘、鑿(zao)子(zi)把兩法(fa)蘭(lan)(lan)之(zhi)(zhi)間(jian)鑿(zao)開(kai)大(da)(da)約1cm的縫隙，用螺(luo)絲(si)刀(dao)把石(shi)棉(mian)(mian)墊(dian)(dian)鑲(xiang)在(zai)兩法(fa)蘭(lan)(lan)之(zhi)(zhi)間(jian)，有時(shi)管(guan)子(zi)頂(ding)部(bu)兩法(fa)蘭(lan)(lan)間(jian)距較(jiao)大(da)(da)，石(shi)棉(mian)(mian)墊(dian)(dian)鑲(xiang)嵌(qian)困(kun)難，用綁(bang)絲(si)把石(shi)棉(mian)(mian)墊(dian)(dian)綁(bang)在(zai)螺(luo)栓上(shang)固定，然后(hou)工(gong)人開(kai)始對稱鎖緊螺(luo)絲(si)。直至從外觀看兩法(fa)蘭(lan)(lan)之(zhi)(zhi)間(jian)只有2—3mm的縫隙即可。

　　(4) 聲測管(guan)管(guan)壁(bi)內(nei)(nei)外防滲(shen)處理(li)：管(guan)壁(bi)內(nei)(nei)外涂(tu)乳化瀝(li)青(qing)(qing)或熱瀝(li)青(qing)(qing)兩(liang)道(dao)，從(cong)外觀(guan)看(kan)管(guan)壁(bi)內(nei)(nei)外均勻(yun)的涂(tu)成了黑管(guan)即可。一般瀝(li)青(qing)(qing)涂(tu)層(ceng)的厚度(du)要達到1mm。
