      春风送暖,喜(xi)报连连。近日,北京市(shi)住房和城乡建设(she)委员会发布了最(zui)新工(gong)法审定结果,万兴集团编制的两(liang)项工(gong)法(软弱地层联拱隧道(dao)坡面条(tiao)件下(xia)套拱+大管棚进洞(dong)施工(gong)工(gong)法、主线管廊内暗作并列竖(shu)井及下(xia)层支(zhi)线管廊隧道(dao)施工(gong)工(gong)法)被评(ping)为北京市(shi)市(shi)级工(gong)法。

 

        此次(ci)最(zui)新(xin)评(ping)审出(chu)的(de)两项(xiang)市级工(gong)(gong)法,是(shi)依托集(ji)团公(gong)司承建的(de)北京新(xin)机场永兴(xing)河北路(lu)道(dao)路(lu)市政手机购彩(cai)管廊工(gong)(gong)程,为解(jie)决软弱(ruo)地层坡面(mian)条件下进洞(dong)加固难度(du)大、垂(chui)直叠落(luo)支线管廊无竖井施工(gong)(gong)工(gong)(gong)作(zuo)面(mian)的(de)难题(ti),而探索出(chu)的(de)新(xin)的(de)施工(gong)(gong)方(fang)法。

 

       软弱地(di)(di)层联拱(gong)隧(sui)(sui)道坡面条件下(xia)套(tao)拱(gong)+大管棚进洞(dong)(dong)施(shi)工(gong)(gong)(gong)工(gong)(gong)(gong)法(fa):改变了(le)传(chuan)统的(de)洞(dong)(dong)口加固方(fang)式,着眼于在进入(ru)隧(sui)(sui)道前(qian)先在隧(sui)(sui)道周边构建受力(li)体(ti)系明确,传(chuan)力(li)可靠的(de)洞(dong)(dong)口加固结构,然后进入(ru)隧(sui)(sui)道施(shi)工(gong)(gong)(gong)。采用本工(gong)(gong)(gong)法(fa)加固施(shi)工(gong)(gong)(gong)洞(dong)(dong)口,洞(dong)(dong)口部位上覆地(di)(di)层荷载(zai)(zai)传(chuan)递(di)给承载(zai)(zai)拱(gong),承载(zai)(zai)拱(gong)所(suo)承受的(de)部分(fen)荷载(zai)(zai)由大管棚承担,其(qi)余荷载(zai)(zai)传(chuan)递(di)给两侧的(de)承载(zai)(zai)墙,通过承载(zai)(zai)墙传(chuan)递(di)给地(di)(di)梁和地(di)(di)梁下(xia)的(de)地(di)(di)基(ji)土。该工(gong)(gong)(gong)法(fa)技术先进,可操作(zuo)性强,施(shi)工(gong)(gong)(gong)质量可靠,经(jing)济效(xiao)益(yi)和社会效(xiao)益(yi)显著,具有推(tui)广应用前(qian)景。

 

        主(zhu)线(xian)(xian)管(guan)(guan)(guan)廊(lang)(lang)(lang)内暗(an)(an)作(zuo)并(bing)(bing)列(lie)(lie)竖井(jing)(jing)及下(xia)层(ceng)支(zhi)(zhi)线(xian)(xian)管(guan)(guan)(guan)廊(lang)(lang)(lang)隧(sui)(sui)(sui)(sui)道(dao)(dao)施(shi)工(gong)(gong)工(gong)(gong)法(fa):对垂直(zhi)叠落(luo)支(zhi)(zhi)线(xian)(xian)管(guan)(guan)(guan)廊(lang)(lang)(lang)隧(sui)(sui)(sui)(sui)道(dao)(dao)施(shi)工(gong)(gong)有了新的(de)(de)突破,即在主(zhu)线(xian)(xian)管(guan)(guan)(guan)廊(lang)(lang)(lang)跨度较大的(de)(de)水(shui)舱隧(sui)(sui)(sui)(sui)道(dao)(dao)内,从隧(sui)(sui)(sui)(sui)道(dao)(dao)底板垂直(zhi)于支(zhi)(zhi)线(xian)(xian)管(guan)(guan)(guan)廊(lang)(lang)(lang)隧(sui)(sui)(sui)(sui)道(dao)(dao)轴线(xian)(xian)向(xiang)下(xia)开挖并(bing)(bing)列(lie)(lie)式(shi)竖井(jing)(jing),利(li)用暗(an)(an)作(zuo)并(bing)(bing)列(lie)(lie)式(shi)竖井(jing)(jing)作(zuo)为支(zhi)(zhi)线(xian)(xian)各个(ge)管(guan)(guan)(guan)廊(lang)(lang)(lang)隧(sui)(sui)(sui)(sui)道(dao)(dao)的(de)(de)施(shi)工(gong)(gong)竖井(jing)(jing),并(bing)(bing)列(lie)(lie)竖井(jing)(jing)的(de)(de)数(shu)量与支(zhi)(zhi)线(xian)(xian)管(guan)(guan)(guan)廊(lang)(lang)(lang)隧(sui)(sui)(sui)(sui)道(dao)(dao)数(shu)量相同(tong)。重点是,该工(gong)(gong)法(fa)用于下(xia)层(ceng)支(zhi)(zhi)线(xian)(xian)管(guan)(guan)(guan)廊(lang)(lang)(lang)隧(sui)(sui)(sui)(sui)道(dao)(dao)施(shi)工(gong)(gong)的(de)(de)竖井(jing)(jing)完全(quan)暗(an)(an)作(zuo),不需要另外提供施(shi)工(gong)(gong)场地,对周边环境影响较小,竖井(jing)(jing)既是支(zhi)(zhi)线(xian)(xian)管(guan)(guan)(guan)廊(lang)(lang)(lang)隧(sui)(sui)(sui)(sui)道(dao)(dao)的(de)(de)施(shi)工(gong)(gong)通道(dao)(dao),又是管(guan)(guan)(guan)廊(lang)(lang)(lang)隧(sui)(sui)(sui)(sui)道(dao)(dao)结构的(de)(de)一部分,减少了成(cheng)本。

 

       多年来,万兴(xing)集团始终以科(ke)(ke)技(ji)创新(xin)(xin)驱(qu)动企业(ye)(ye)发(fa)(fa)展(zhan),依托(tuo)“北京市企业(ye)(ye)技(ji)术中心”和“BIM技(ji)术中心”两大平台,落实科(ke)(ke)技(ji)手(shou)机购(gou)彩(cai)和技(ji)术创新(xin)(xin)工(gong)(gong)作。截至目(mu)前,集团已累计获(huo)得专利技(ji)术、工(gong)(gong)法(fa)、科(ke)(ke)技(ji)成(cheng)果鉴(jian)定(ding)、行业(ye)(ye)及国家标准(zhun)、示(shi)范工(gong)(gong)程等(deng)210余项(xiang),科(ke)(ke)技(ji)创新(xin)(xin)排(pai)名在北京市一级企业(ye)(ye)中位(wei)居前三(san)。此(ci)次万兴(xing)集团再次荣(rong)获(huo)两项(xiang)市级工(gong)(gong)法(fa),为后续(xu)公司(si)同类工(gong)(gong)程施工(gong)(gong)积累了(le)可靠的(de)(de)借鉴(jian)经验,同时也展(zhan)示(shi)了(le)万兴(xing)集团科(ke)(ke)技(ji)创新(xin)(xin)实力,实现了(le)良好的(de)(de)经济和社会效益,发(fa)(fa)挥了(le)科(ke)(ke)技(ji)创新(xin)(xin)对公司(si)发(fa)(fa)展(zhan)的(de)(de)助推作用。
