v多塔作業(yè)施工方案(更新版)
【正文】 deformation small。、結(jié)構(gòu)形式，計(jì)劃在基礎(chǔ)、主體結(jié)構(gòu)施工時(shí)安裝兩臺(tái)自升式TCT7015塔吊，完成垂直作業(yè)任務(wù)。為杜絕此類事故發(fā)生，塔吊使用前必須對(duì)每一臺(tái)塔吊的工作區(qū)進(jìn)行合理劃分，盡量避免減少出現(xiàn)塔吊交叉工作區(qū)。 ，吊鉤繩與大臂的距離不得小于5米。 對(duì)嚴(yán)格限制塔臂回轉(zhuǎn)角度的塔吊，要采取塔臂回轉(zhuǎn)限制措施。 換班時(shí)，采用當(dāng)面交接制 塔吊與信號(hào)指揮人員應(yīng)配備對(duì)講機(jī)，對(duì)講機(jī)統(tǒng)一確定頻率后必須鎖頻，使用人員無(wú)權(quán)調(diào)改頻率，要專機(jī)專用，不得轉(zhuǎn)借。 在被吊物跨越幅度大的情況下，要確保安全可靠，杜絕發(fā)生“天女散花”的現(xiàn)象。 保證塔吊塔身的垂直度不超過(guò)4‰。 作業(yè)現(xiàn)場(chǎng)必須設(shè)置不小于20X20米（以塔吊的回轉(zhuǎn)中心為中心）的安全作業(yè)區(qū)，非塔吊拆裝人員嚴(yán)禁入內(nèi)。 4級(jí)風(fēng)以上嚴(yán)禁頂升作業(yè)，5級(jí)風(fēng)以上嚴(yán)禁塔吊附著安裝。塔吊的各項(xiàng)安全限位必須安全可靠。 在塔吊交叉區(qū)域內(nèi)設(shè)立監(jiān)護(hù)哨，作業(yè)層面設(shè)立一名指揮哨，防止令出多人，造成混亂碰撞。12. 多塔作業(yè)綜合管理規(guī)定 施工期間建立多塔綜合管理規(guī)定 施工期間建立多塔作業(yè)指揮中心，并研究制定“多塔作業(yè)綜合管理制度” 進(jìn)場(chǎng)塔機(jī)要符合規(guī)定要求，塔機(jī)安裝單位資質(zhì)要求、塔機(jī)驗(yàn)收要求，對(duì)塔機(jī)司機(jī)、信號(hào)工、起重工的培訓(xùn)，統(tǒng)一信號(hào)和部分塔機(jī)限制臂的要求，群塔作業(yè)管理規(guī)定和獎(jiǎng)勵(lì)處罰辦法。 between pile and pile through the pile top beam and wall purlins into overall and thus relatively poor overall, as in important areas, special projects and large Foundation pit in excavation depth application requires special care. steel piles using steel piles supporting the Foundation pit for temporary support features, construction convenient, short, finished construction in Foundation pit backfill after the channel pulled out, reuse, can minimize the cost of support. Used steel piles supporting a fatal weakness, that is impervious to water and small soil particles, and also called as high water precipitation or water, and the underground water level is high, waterrich geological conditions did not match. Flexural capacity of steel sheet pile supporting weaker excavation depth does not exceed 4m deflection of more general application. Obviously the soft water of Foundation pit excavation depth of geological conditions of 10m, and is located in the city centres of Flex ... Limited to, work hard, and it can take full advantage of building line the walls within a limited number of ground and space, can give full play to its economic benefits, in the course of construction, 北京蜀東城市建設(shè)工程有限公司順義新城28街區(qū)5地塊商業(yè)設(shè)施項(xiàng)目項(xiàng)目部
