多錘頭破碎機施工時的質量控制要(yao)求(qiu)

　1、碎化(hua)要求：水泥砼破(po)碎達到(dao)75%以上；表(biao)面層粒(li)徑的尺(chi)寸(cun)不超(chao)過(guo)7.5cm（型壓(ya)路機穩定壓(ya)2遍時(shi)），其深度應不少于6cm，中間層粒(li)徑不超(chao)過(guo)22.5cm；底(di)層料徑不超(chao)過(guo)37.5cm，多(duo)錘頭破(po)碎機施工時(shi)采用刨坑檢查，游標卡尺(chi)量(liang)其粒(li)徑不超(chao)過(guo)7.5cm。

2、破(po)碎(sui)(sui)順序及搭接寬(kuan)度要求：多錘頭破(po)碎(sui)(sui)機破(po)碎(sui)(sui)時(shi)應從路的高處往低處進行破(po)碎(sui)(sui)，破(po)碎(sui)(sui)的寬(kuan)度應超過(guo)一個(ge)車道，破(po)碎(sui)(sui)搭接寬(kuan)度在(zai)15cm以(yi)上，板塊破(po)1裂邊長(chang)為30-60厘(li)米，超過(guo)60厘(li)米邊長(chang)不(bu)得大于30%，不(bu)得形(xing)成大面積的板塊破(po)碎(sui)(sui)。

影響碎石化機械價格的因素

　生產成(cheng)(cheng)(cheng)(cheng)本：生產成(cheng)(cheng)(cheng)(cheng)本包括(kuo)原(yuan)材料成(cheng)(cheng)(cheng)(cheng)本和(he)(he)投資(zi)成(cheng)(cheng)(cheng)(cheng)本兩個(ge)(ge)方面(mian)：①原(yuan)材料成(cheng)(cheng)(cheng)(cheng)本是(shi)影響設備價(jia)(jia)格的直接因(yin)素，比如鋼材，其(qi)價(jia)(jia)格波(bo)動會直接影響鋼材市場股1市化的發展趨勢(shi)，引起(qi)鋼材貿易操(cao)作模式的轉變；②投資(zi)成(cheng)(cheng)(cheng)(cheng)本是(shi)廠家成(cheng)(cheng)(cheng)(cheng)本總(zong)和(he)(he)的一個(ge)(ge)重要(yao)組成(cheng)(cheng)(cheng)(cheng)部分，包括(kuo)員工(gong)工(gong)資(zi)、研(yan)發資(zi)金(jin)、廠房擴建及(ji)設備折舊等多個(ge)(ge)方面(mian)，投資(zi)成(cheng)(cheng)(cheng)(cheng)本的增加需要(yao)使成(cheng)(cheng)(cheng)(cheng)本總(zong)和(he)(he)上(shang)升，為了維護自身的正當利益(yi)及(ji)后續發展，廠家會調整反擊式破(po)碎機的價(jia)(jia)格。

材料級配的不合理

　　由于施(shi)(shi)工(gong)(gong)(gong)過(guo)程(cheng)(cheng)中(zhong)(zhong)施(shi)(shi)工(gong)(gong)(gong)單位(wei)偷工(gong)(gong)(gong)減料，在(zai)其施(shi)(shi)工(gong)(gong)(gong)過(guo)程(cheng)(cheng)中(zhong)(zhong)所選用(yong)的材料不(bu)能(neng)(neng)(neng)嚴格按(an)照級配要(yao)求(qiu)，造(zao)成面板的彎曲應力不(bu)能(neng)(neng)(neng)滿(man)足(zu)設(she)計要(yao)求(qiu)，施(shi)(shi)工(gong)(gong)(gong)過(guo)程(cheng)(cheng)中(zhong)(zhong)容易(yi)產生裂(lie)縫。鑒(jian)于農村(cun)公路(lu)(lu)(lu)經費有限，導致(zhi)(zhi)施(shi)(shi)工(gong)(gong)(gong)方在(zai)填路(lu)(lu)(lu)過(guo)程(cheng)(cheng)中(zhong)(zhong)用(yong)采砂礫石(shi)替代(dai)碎石(shi)進行施(shi)(shi)工(gong)(gong)(gong)，而在(zai)施(shi)(shi)工(gong)(gong)(gong)過(guo)程(cheng)(cheng)中(zhong)(zhong)材料不(bu)符合導致(zhi)(zhi)相關級配難(nan)以(yi)(yi)滿(man)足(zu)要(yao)求(qiu)而造(zao)成后期(qi)施(shi)(shi)工(gong)(gong)(gong)質量不(bu)能(neng)(neng)(neng)符合要(yao)求(qiu)。除此以(yi)(yi)外，農村(cun)公路(lu)(lu)(lu)設(she)計等級低，材料選擇隨意，導致(zhi)(zhi)施(shi)(shi)工(gong)(gong)(gong)中(zhong)(zhong)把關不(bu)嚴，材料性能(neng)(neng)(neng)難(nan)以(yi)(yi)滿(man)足(zu)設(she)計要(yao)求(qiu)，導致(zhi)(zhi)農村(cun)公路(lu)(lu)(lu)耐久性不(bu)足(zu)。
