本(ben)發明(ming)涉及建筑施(shi)工(gong),具(ju)體是一種(zhong)狹小水(shui)平風道井(jing)一次成型施(shi)工(gong)方法(fa)。
背景技術:
1、為節約有(you)限空(kong)間資(zi)源,城(cheng)市(shi)新建筑(zhu)(zhu)日趨向(xiang)地下(xia)發(fa)展,地下(xia)車(che)庫、地下(xia)商場等(deng)與百姓生(sheng)活密切的(de)(de)地下(xia)工(gong)(gong)程越來越多(duo),為保證地下(xia)空(kong)間空(kong)氣流通(tong)性,地下(xia)室(shi)(shi)送排風井是必不可少的(de)(de)構(gou)(gou)造(zao)之一。為提(ti)高(gao)空(kong)間利(li)用(yong)率,地下(xia)室(shi)(shi)送排風風道(dao)(dao)(dao)井結(jie)(jie)構(gou)(gou)尺寸狹小,且(qie)水平(ping)風道(dao)(dao)(dao)井頂(ding)(ding)板(ban)(ban)(ban)(ban)設計上(shang)往往和地下(xia)室(shi)(shi)頂(ding)(ding)板(ban)(ban)(ban)(ban)共(gong)用(yong)。由于風道(dao)(dao)(dao)井尺寸狹小,如果(guo)將風道(dao)(dao)(dao)井四(si)周井壁模板(ban)(ban)(ban)(ban)全部安(an)裝(zhuang)完成,會造(zao)成澆(jiao)(jiao)筑(zhu)(zhu)過程中施(shi)(shi)(shi)工(gong)(gong)人員無法對(dui)底(di)(di)板(ban)(ban)(ban)(ban)進行(xing)振搗和收面。因(yin)此在施(shi)(shi)(shi)工(gong)(gong)過程中,水平(ping)風道(dao)(dao)(dao)井的(de)(de)澆(jiao)(jiao)筑(zhu)(zhu)需(xu)要分成兩部分施(shi)(shi)(shi)工(gong)(gong),先澆(jiao)(jiao)筑(zhu)(zhu)底(di)(di)板(ban)(ban)(ban)(ban),待底(di)(di)板(ban)(ban)(ban)(ban)終凝后再進行(xing)頂(ding)(ding)板(ban)(ban)(ban)(ban)和側(ce)壁的(de)(de)架體搭設、模板(ban)(ban)(ban)(ban)安(an)裝(zhuang)及澆(jiao)(jiao)筑(zhu)(zhu),這樣的(de)(de)施(shi)(shi)(shi)工(gong)(gong)工(gong)(gong)序會使側(ce)壁產生(sheng)施(shi)(shi)(shi)工(gong)(gong)縫,造(zao)成漏風的(de)(de)隱患。另外,如果(guo)水平(ping)風道(dao)(dao)(dao)井底(di)(di)板(ban)(ban)(ban)(ban)和墻(qiang)(qiang)體或(huo)者構(gou)(gou)造(zao)柱(zhu)連接在一起,還(huan)需(xu)要把相鄰的(de)(de)墻(qiang)(qiang)體或(huo)者構(gou)(gou)造(zao)柱(zhu)同(tong)時澆(jiao)(jiao)筑(zhu)(zhu)到(dao)風道(dao)(dao)(dao)井底(di)(di)板(ban)(ban)(ban)(ban)位置,會造(zao)成較(jiao)大(da)范(fan)圍的(de)(de)施(shi)(shi)(shi)工(gong)(gong)縫產生(sheng)。尤其是涉(she)及到(dao)人防(fang)工(gong)(gong)程,所(suo)有(you)結(jie)(jie)構(gou)(gou)必須達到(dao)一次(ci)性澆(jiao)(jiao)筑(zhu)(zhu)的(de)(de)要求(qiu),底(di)(di)板(ban)(ban)(ban)(ban)、側(ce)壁和頂(ding)(ding)板(ban)(ban)(ban)(ban)分次(ci)澆(jiao)(jiao)筑(zhu)(zhu)的(de)(de)施(shi)(shi)(shi)工(gong)(gong)方(fang)法根本無法滿足(zu)設計要求(qiu)。為此研(yan)究一種狹小水平(ping)風道(dao)(dao)(dao)井一次(ci)性成型施(shi)(shi)(shi)工(gong)(gong)方(fang)法技(ji)術(shu)尤為重要。
