你知道管道刷用于哪些地方吗?

管道(dao)刷,又名(ming)清孔(kong)刷,是毛刷的重要品种,其在修建植(zhi)(zhi)筋(jin)(jin)(jin)加固(gu)施工工艺中有着广泛运用,下文做简略剖析。首先看(kan)植(zhi)(zhi)筋(jin)(jin)(jin)工序,主要由底层,整理,标定,方位,钻孔(kong),清孔(kong),装备张贴剂,注入(ru)张贴剂,植(zhi)(zhi)入(ru)钢筋(jin)(jin)(jin),静置故(gu)化,查验查验等组成。

 


钻孔(kong)前,应(ying)核(he)对(dui)底(di)层(ceng)(ceng)强度(du)并对(dui)外表情况(裂缝和其它缺(que)点)进行检查。将外表整理洁净后(hou)按规划(hua)图,在底(di)层(ceng)(ceng)上标明(ming)需(xu)植(zhi)筋方位(wei)(wei)。钻孔(kong)时(shi),钻头(tou)应(ying)垂(chui)直于(yu)工作面并标明(ming)规划(hua)埋(mai)深(shen)尺度(du),钻入(ru)时(shi),不得晃动过大,形成歪(wai)斜或违背(bei)规划(hua)方位(wei)(wei)。钻(zuan)入(ru)进(jin)程中如遇钢筋(jin)(jin),应(ying)立(li)即中止(zhi)。在原(yuan)处邻(lin)近从头钻(zuan)孔(kong)(kong)。新孔(kong)(kong)与(yu)规划孔(kong)(kong)之间(jian)净间(jian)隔应(ying)≤2倍植(zhi)筋(jin)(jin)直径,与(yu)欲烧(shao)混(hun)凝土构件外边间(jian)隔不得(de)小于保护层厚度(du)。废孔(kong)(kong)用(yong)沙浆填满。如规划赞同堵(du)截原(yuan)有钢筋(jin)(jin),可采用(yong)切(qie)开钢筋(jin)(jin)用(yong)钻(zuan)孔(kong)(kong)机,切(qie)断钢筋(jin)(jin),钻(zuan)孔(kong)(kong)至(zhi)规划深度(du)。清(qing)孔(kong)(kong)可先用吹风筒或高压空气(qi)将孔(kong)(kong)内(nei)粉(fen)尘(chen)吹出,再(zai)用清(qing)孔(kong)(kong)刷清(qing)孔(kong)(kong),重复操(cao)作,直(zhi)至(zhi)孔(kong)(kong)底(di)无积(ji)灰。清(qing)孔(kong)(kong)不得用水,孔(kong)(kong)内(nei)如有积(ji)水应(ying)铲除。粘结剂(ji)装备应(ying)由专人担任,保证数量正确,拌合均匀,再(zai)注入前(qian)无凝结现象。将粘(zhan)(zhan)(zhan)结(jie)(jie)(jie)剂注入(ru)孔(kong)(kong)内,应(ying)(ying)立即刺进钢筋,按顺时(shi)针方向边转(zhuan)边插直至孔(kong)(kong)底(di),是粘(zhan)(zhan)(zhan)结(jie)(jie)(jie)剂部分溢出(chu),刮去外表剩余粘(zhan)(zhan)(zhan)结(jie)(jie)(jie)剂。悉(xi)数进程所耗时(shi)刻(ke)应(ying)(ying)小于粘(zhan)(zhan)(zhan)结(jie)(jie)(jie)剂初凝时(shi)刻(ke)。否则应(ying)(ying)铲除粘(zhan)(zhan)(zhan)结(jie)(jie)(jie)剂,从头(tou)进行清孔(kong)(kong)等工序。
