隧道設計q235腳手架(jia)鋼管需求(qiu)

作者:精密管 來源:dfzx365.com 點擊數: 更新時間:2019年12月19 【字體:

 為了保證施工安全,隧道設計q235腳手架鋼管需求(qiu) 隧道(dao)施(shi)工(gong)(gong)中(zhong)經常(chang)會遇到各種(zhong)地質(zhi)的(de)(de)(de)圍巖。鋼(gang)(gang)(gang)(gang)(gang)拱(gong)架(jia)(jia)(jia)(jia)作(zuo)為(wei)(wei)初期最常(chang)見(jian)的(de)(de)(de)一種(zhong)支護(hu)方(fang)式,其中(zhong)型(xing)鋼(gang)(gang)(gang)(gang)(gang)拱(gong)架(jia)(jia)(jia)(jia)的(de)(de)(de)應用最為(wei)(wei)頻繁。其具體的(de)(de)(de)施(shi)工(gong)(gong)過程為(wei)(wei):鋼(gang)(gang)(gang)(gang)(gang)拱(gong)架(jia)(jia)(jia)(jia)通(tong)常(chang)都是按照隧道(dao)所處圍巖的(de)(de)(de)尺寸進(jin)行設計(ji)并在隧道(dao)外的(de)(de)(de)加工(gong)(gong)廠內(nei)分節加工(gong)(gong)。施(shi)工(gong)(gong)時,將其運至(zhi)隧道(dao)掌子面(mian)開挖現場,與開挖面(mian)錨桿焊接定位后,進(jin)一步(bu)在鋼(gang)(gang)(gang)(gang)(gang)拱(gong)架(jia)(jia)(jia)(jia)間縱向(xiang)連接鋼(gang)(gang)(gang)(gang)(gang)筋(jin)及鋼(gang)(gang)(gang)(gang)(gang)筋(jin)網片(pian),最后對(dui)鋼(gang)(gang)(gang)(gang)(gang)筋(jin)網片(pian)及型(xing)鋼(gang)(gang)(gang)(gang)(gang)拱(gong)架(jia)(jia)(jia)(jia)進(jin)行噴射混(hun)凝土完成初步(bu)的(de)(de)(de)隧道(dao)加固。傳統(tong)型(xing)鋼(gang)(gang)(gang)(gang)(gang)彎折加工(gong)(gong)是將型(xing)鋼(gang)(gang)(gang)(gang)(gang)通(tong)過彎曲機彎折到設計(ji)所要求(qiu)的(de)(de)(de)弧度。根(gen)據不同的(de)(de)(de)q235腳手架(jia)(jia)(jia)(jia)鋼(gang)(gang)(gang)(gang)(gang)管隧道(dao)設計(ji)需求(qiu),鋼(gang)(gang)(gang)(gang)(gang)拱(gong)架(jia)(jia)(jia)(jia)采用型(xing)鋼(gang)(gang)(gang)(gang)(gang)的(de)(de)(de)規格、長(chang)度也不盡相同,一般為(wei)(wei)210米(mi),其重量(liang)約為(wei)(wei)120~400kg可(ke)見(jian)鋼(gang)(gang)(gang)(gang)(gang)拱(gong)架(jia)(jia)(jia)(jia)加工(gong)(gong)需要較大的(de)(de)(de)操作(zuo)空間。

     
其加工過程至少需要2人從彎曲機一端將型鋼原材送入,同時需要2人從另一端將經過彎折后的拱架抬起,加工生產中的4人需跟隨伸出的彎曲拱架而不斷進行移動,直至加工完成后方可將弧形拱架搬運到指定地點存放。整個加工過程中存在以下缺點:整個過程需要1名彎曲機操作人員以及4名輔助搬運人員共計5人才可以完成,人工浪費現象嚴重;由于型鋼拱架重量大、長度長且加工時人員需不斷跟隨經過彎曲機的拱架進行移動,由于拱架的形狀、規格及大小不同,加工作業面的限制,加工時無法采取有效起吊工具進行協助,不僅費時費力,更嚴重的極易出現人員擦傷、磕碰等情況。腳手架鋼管建(jian)(jian)(jian)筑(zhu)(zhu)工(gong)(gong)(gong)(gong)(gong)(gong)程(cheng),指(zhi)(zhi)通(tong)過(guo)對各類房屋(wu)建(jian)(jian)(jian)筑(zhu)(zhu)及(ji)其(qi)附(fu)屬設(she)施(shi)(shi)的(de)(de)(de)(de)建(jian)(jian)(jian)造和(he)(he)與其(qi)配套(tao)的(de)(de)(de)(de)線(xian)(xian)路(lu)、管(guan)道(dao)、設(she)備(bei)的(de)(de)(de)(de)安(an)裝活(huo)動(dong)所(suo)形(xing)成(cheng)的(de)(de)(de)(de)工(gong)(gong)(gong)(gong)(gong)(gong)程(cheng)實(shi)體。其(qi)中“房屋(wu)建(jian)(jian)(jian)筑(zhu)(zhu)”指(zhi)(zhi)有頂(ding)蓋、梁(liang)柱、墻壁、基礎以及(ji)能夠(gou)形(xing)成(cheng)內(nei)部空(kong)間,滿足(zu)人(ren)們生(sheng)產、居住、學(xue)習、公共活(huo)動(dong)需要的(de)(de)(de)(de)工(gong)(gong)(gong)(gong)(gong)(gong)程(cheng)。建(jian)(jian)(jian)筑(zhu)(zhu)工(gong)(gong)(gong)(gong)(gong)(gong)程(cheng)是為新建(jian)(jian)(jian)、改建(jian)(jian)(jian)或擴建(jian)(jian)(jian)房屋(wu)建(jian)(jian)(jian)筑(zhu)(zhu)物(wu)(wu)和(he)(he)附(fu)屬構(gou)筑(zhu)(zhu)物(wu)(wu)設(she)施(shi)(shi)所(suo)進行(xing)的(de)(de)(de)(de)規劃、勘察、設(she)計(ji)和(he)(he)施(shi)(shi)工(gong)(gong)(gong)(gong)(gong)(gong)、竣工(gong)(gong)(gong)(gong)(gong)(gong)等各項技術工(gong)(gong)(gong)(gong)(gong)(gong)作(zuo)和(he)(he)完成(cheng)的(de)(de)(de)(de)工(gong)(gong)(gong)(gong)(gong)(gong)程(cheng)實(shi)體以及(ji)與其(qi)配套(tao)的(de)(de)(de)(de)線(xian)(xian)路(lu)、管(guan)道(dao)、設(she)備(bei)的(de)(de)(de)(de)安(an)裝工(gong)(gong)(gong)(gong)(gong)(gong)程(cheng)。也指(zhi)(zhi)各種房屋(wu)、建(jian)(jian)(jian)筑(zhu)(zhu)物(wu)(wu)的(de)(de)(de)(de)建(jian)(jian)(jian)造工(gong)(gong)(gong)(gong)(gong)(gong)程(cheng),又稱建(jian)(jian)(jian)筑(zhu)(zhu)工(gong)(gong)(gong)(gong)(gong)(gong)作(zuo)量。建(jian)(jian)(jian)筑(zhu)(zhu)工(gong)(gong)(gong)(gong)(gong)(gong)程(cheng)中,q235腳手(shou)(shou)(shou)架鋼管(guan)腳手(shou)(shou)(shou)架(scaffold指(zhi)(zhi)施(shi)(shi)工(gong)(gong)(gong)(gong)(gong)(gong)現(xian)場為工(gong)(gong)(gong)(gong)(gong)(gong)人(ren)操作(zuo)并解決(jue)垂直和(he)(he)水平運輸而搭(da)設(she)的(de)(de)(de)(de)各種支架。現(xian)有技術中,腳手(shou)(shou)(shou)架均是采用類似于鋼管(guan)的(de)(de)(de)(de)材(cai)料,腳手(shou)(shou)(shou)架鋼管(guan)在(zai)長(chang)時間的(de)(de)(de)(de)日曬(shai)雨淋后(hou)會(hui)生(sheng)銹,為了(le)延長(chang)腳手(shou)(shou)(shou)架鋼管(guan)的(de)(de)(de)(de)使用壽命和(he)(he)保障(zhang)施(shi)(shi)工(gong)(gong)(gong)(gong)(gong)(gong)的(de)(de)(de)(de)安(an)全(quan)性,腳手(shou)(shou)(shou)架在(zai)一(yi)(yi)次使用后(hou)均會(hui)進行(xing)維護保養,一(yi)(yi)般是除(chu)銹和(he)(he)涂上防(fang)銹油,這些工(gong)(gong)(gong)(gong)(gong)(gong)序一(yi)(yi)般都(dou)是通(tong)過(guo)人(ren)工(gong)(gong)(gong)(gong)(gong)(gong)來進行(xing)的(de)(de)(de)(de)其(qi)勞(lao)動(dong)量較大,需要的(de)(de)(de)(de)工(gong)(gong)(gong)(gong)(gong)(gong)人(ren)較多,從而導(dao)致維護成(cheng)本q235腳手(shou)(shou)(shou)架鋼管(guan)的(de)(de)(de)(de)升高。
