強烈的(de)信仰(yang)會贏取(qu)堅強的(de)人(ren),然(ran)后又使(shi)他(ta)們更堅強.達奧鋼管一五(wu)七三(san)三(san)七〇八八〇一高姍
混(hun)凝土灌注樁以其承載力大、沉(chen)降小、能(neng)適(shi)應各種地形地質(zhi)條件和(he)各種重大土工構筑物,對基礎承載力的需要等特點而被(bei)廣泛采用.
但由于灌注(zhu)樁(zhuang)(zhuang)屬地(di)下隱蔽工(gong)(gong)程,施(shi)工(gong)(gong)工(gong)(gong)藝復雜,在施(shi)工(gong)(gong)過(guo)程中,常遇(yu)到各種工(gong)(gong)程地(di)質問(wen)題如(ru)地(di)下水滲(shen)流、流沙層(ceng)、淤泥(ni)(ni)層(ceng),引(yin)起塌孔和(he)縮徑(jing),以(yi)及混凝(ning)土(tu)(tu)灌注(zhu)過(guo)程中,容易出現各種問(wen)題使(shi)(shi)樁(zhuang)(zhuang)產(chan)生離析、夾泥(ni)(ni)、斷(duan)樁(zhuang)(zhuang)、縮徑(jing)等樁(zhuang)(zhuang)身缺陷,將對(dui)(dui)橋梁、路基(ji)等土(tu)(tu)工(gong)(gong)構筑物的正常使(shi)(shi)用造成隱患. 因此,對(dui)(dui)混凝(ning)土(tu)(tu)灌注(zhu)樁(zhuang)(zhuang)的質量(liang)檢(jian)測是(shi)十分重(zhong)要的.
按照鐵道部"關(guan)于做(zuo)好(hao)客運專線鐵路基樁(zhuang)(zhuang)(zhuang)檢(jian)測(ce)工(gong)(gong)作(zuo)的(de)(de)通知"(鐵建設(she)函)的(de)(de)技術要(yao)求(qiu),對(dui)(dui)混凝(ning)土灌注樁(zhuang)(zhuang)(zhuang)應(ying)按其(qi)基樁(zhuang)(zhuang)(zhuang)總數的(de)(de)100%做(zuo)無(wu)損(sun)(sun)檢(jian)測(ce).當(dang)基樁(zhuang)(zhuang)(zhuang)混凝(ning)土強度達到設(she)計強度的(de)(de)70%,且不小于15MPa,方可進行(xing)無(wu)損(sun)(sun)檢(jian)測(ce).對(dui)(dui)于地(di)質變化(hua)異常(chang)復雜地(di)聲測(ce)管區的(de)(de)混凝(ning)土灌注樁(zhuang)(zhuang)(zhuang),樁(zhuang)(zhuang)(zhuang)身質量應(ying)采(cai)用聲波(bo)透射(she)法進行(xing)檢(jian)測(ce)及驗(yan)收. 在樁(zhuang)(zhuang)(zhuang)基施(shi)工(gong)(gong)過程中(zhong),聲測(ce)管的(de)(de)施(shi)工(gong)(gong)是樁(zhuang)(zhuang)(zhuang)基檢(jian)測(ce)工(gong)(gong)作(zuo)中(zhong)的(de)(de)基礎(chu)工(gong)(gong)作(zuo),是正確檢(jian)測(ce)評價樁(zhuang)(zhuang)(zhuang)基完整性的(de)(de)關(guan)鍵工(gong)(gong)序,一(yi)定要(yao)引起高度重(zhong)視.
