style="text-indent:25px">橋梁工程結(jié)構(gòu)形式多樣，因地質(zhì)、水文及公路等級、使用要求的不同而有不同的設(shè)計(jì)。如地質(zhì)較好的山區(qū)橋梁，采用淺基礎(chǔ)形式而沖積平原的橋梁基礎(chǔ)，多采用深基礎(chǔ)；如大型橋梁跨越主河道，鋼箱梁的結(jié)構(gòu)形式會與引橋的結(jié)構(gòu)形式有很大的不同。為了按計(jì)劃正常施工，建設(shè)、設(shè)計(jì)、監(jiān)理、施工單位必須密切配合材料、動(dòng)力、運(yùn)輸各部門應(yīng)全力協(xié)作，地方各級地方部門和沿線的各相關(guān)單位的團(tuán)結(jié)協(xié)作也不可缺少。因此鋼箱梁工程施工過程中，應(yīng)團(tuán)結(jié)、協(xié)作、協(xié)調(diào)、平衡，才能使施工工作進(jìn)展順利。鋼箱梁工程施工任務(wù)是一次性的，產(chǎn)品的位置是固定不動(dòng)的而且由于每個(gè)項(xiàng)目都有其時(shí)間地點(diǎn)、技術(shù)、經(jīng)濟(jì)等的特殊性每次任務(wù)均具有區(qū)別于其他任務(wù)的特點(diǎn)，不可能像工業(yè)產(chǎn)品一樣復(fù)批量生產(chǎn)，施工過程中由于錯(cuò)誤失誤等造成的損失將無法彌補(bǔ)、無法挽回，因此需要因地制宜重視橋梁工程施工的特性進(jìn)行專門的研究、設(shè)計(jì)，釆用專門的科學(xué)的施工組織與管理。</p><p style="text-indent:25px">有的鋼箱梁適于精加工，有的適于大厚度切割，也有的是在原來工作液中添加某些化學(xué)成分來提高其切割速度或增加防銹能力等。無論哪種工作液都應(yīng)具有一定的絕緣性能、冷卻性能，并且對環(huán)境無污染，對人體無危害①絕緣性能：火花放電必須在具有一定絕緣性能的液體介質(zhì)中進(jìn)行。工作液的絕緣性能可使擊穿后的放電通道壓縮，局限在較小的通道半徑內(nèi)火花放電，形成瞬時(shí)局部高溫熔化、汽化金屬。放電結(jié)束后又迅速恢復(fù)放電間隙成為絕緣狀②冷卻性能：在放電過程中，放電點(diǎn)局部瞬時(shí)溫度極高，尤其是大電流加工時(shí)升溫則更加突出。因此為防止電極絲燒斷和工件表面局部退火，必須充分冷卻，這要求工作液具有較好的吸熱、傳熱、散熱性能。蘇州橋友為您提供深化設(shè)計(jì)到三維自動(dòng)化繪圖，一站式給與解決。</p><div
