随着气温一步步升高,夏季来临,室外施工的考验又来了,天气闷热、雨水增多,夏季是一年中天气极炎热的季节,中午温度达三十多度,空气湿度大,雨水多,给工程施工质量及安全带来了很大的隐患。所以在夏季的四川塑石假山施工中一定要注意防范高温及雨水而造成的损失。由于夏季温度高,对塑石假山施工中的影响很大,例如高温会造成面层水泥砂浆凝固期缩短,进而影响水泥砂浆的强度。所以在施工中可以加遮阳布覆盖,防止阳光直接照射。另外温度过高,造成水泥砂浆开裂,水泥砂浆的伸缩性降低,面层裂纹容易出现。针对这种情况,可以在水泥砂浆中加少许玻璃纤维丝等添加剂加以改善。还有气温高会造成凝固后的水泥砂浆表面温度过高,大大降低水泥砂浆的强度,这种情况下,需多次喷水保养,白天温度高,3小时喷淋一次,入晚上施工则6小时喷淋一次。夏季雷阵雨较多,空气湿度大,对塑石假山施工中初凝水泥砂浆有一定的影响,水泥砂浆塑面层在涂抹后两个小时内,不能淋雨。为防止雨水冲刷,可加塑料薄膜覆盖。夏季施工应以安全施工为主题,防暑降温为重点,切实抓好安全生产,确保工程质量和施工人员的生命健康。避开中午高温期,中午11点至下午3点安排休息,缩短整体施工时间,项目部现场准备遮阳棚,同时准备藿香正气水等防暑降温食品及药品。另外施工人员宿舍内应注意用电安全,加强工地食堂卫生管理,防止变质食品进入食堂,项目部安排专业人员监督管理。ABSolute;top:0;border:0;width:undefinedpx;height:undefinedpx;" sandbox="allow-forms allow-popUPS allow-popups-to-escape-sandbox allow-same-origin allow-scripts allow-top-navigation-by-user-activation" frameborder="0" src="https://googleads.g.doubleclick.net/pagead/ads?guci=2.2.0.0.2.2.0.0&client=ca-pub-6745515041074118&ouTPUt=html&adk=1812271804&adf=3279755396&plat=1%3A32776%2C2%3A32776%2C8%3A134217728%2C9%3A134250504%2C10%3A32%2C11%3A32%2C16%3A8388608%2C17%3A32%2C24%3A32%2C25%3A32%2C30%3A1081344%2C32%3A32%2C40%3A32&format=0x0&url=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fact%3D1&ea=0&flash=32.0.0&pra=5&wgl=1&tt_state=W3siaXNzdWVyT3JpZ2luIjoiaHR0cHM6Ly9hZHNlcnZpY2UuZ29vZ2xlLmNvbSISInN0YXRlIjowfSx7Imlzc3Vlck9yaWdpbiI6Imh0dHBzOi8vYXR0ZXN0YXRpb24uYW5kcm9pZC5jb20iLCJzdGF0ZSI6MH1d&dt=1606655348212&bpp=9&bdt=161&idt=25&shv=r20201112&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3D9ded2fa457d6f61e-22bd73041bc4002c%3AT%3D1602749449%3ART%3D1602749449%3AS%3DALNI_Mak6ViDyzUjLUoqQpucKHXgSK8mcA&nras=1&correlator=5484387157110&frm=23&ife=1&pv=2&ga_vid=2117496.1606655348&ga_sid=1606655348&ga_hid=716091083&ga_fc=0&iag=3&icsg=138&nhd=1&dssz=5&mdo=0&mso=0&u_tz=480&u_his=32&u_java=0&u_h=1080&u_w=1920&u_ah=1040&u_aw=1920&u_cd=24&u_nplug=24&u_nmime=42&adx=-12245933&ady=-12245933&biw=1872&bih=869&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=42530671%2C21066922&oid=3&pvsid=1183200727067573&pem=606&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php&rx=0&eae=2&fc=1664&brdim=0%2C0%2C0%2C0%2C1920%2C0%2C1920%2C1040%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&fu=8204&bc=31&ifi=0&uci=0.hp0mffay1mkt&fsb=1&dtd=48" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="0.hp0mffay1mkt" data-load-complete="true"> |
