12、情况为山区道路半路堑半填方路堤和原山体次坚石,根据地质情况及怀化地区气候情况,采用喷播植草绿色防护边坡。使该工程尽可能达到保护自然环境和防灾减灾功能,以实现营造富有季节色彩变化的坡面自然景观。二、客土喷播绿化特点客土喷播绿化是90年代末从国外引进我国的一种新型绿化技术。是将草种复合肥料、菜枯、锯木屑、保水剂、土壤、有机物、粘合剂等混合物充分混合后,通过水浆喷射机按设计厚度均匀喷至防护坡面,以达到景观近似自然绿化目的。具有如下优点:1)施工工艺简单,施工方便,施工速度快,工期短;2)防护效果好,植株成活率高。3)适用性广。4)工程造价低。三、客土喷播方法的选择:根据当地的气温,降雨量及坡率比、岩
13、石的硬度等因素,采用“锚杆注浆+挂机编热镀锌网+客土+喷草”以增大生长发育基础与坡体的连接性。选择适合的草种配合比,改善绿色植物的生长发育环境和促进目标树种生长的双重功能,以确保喷射效果和质量。客土喷播材料中包括植物种子、有机营养泥炭土、土壤改良剂、稳定剂、微生物菌剂、肥料等。四、客土喷播施工1)施工准备1、选择适合于当地气候条件、易于生长的草种。混合草种应试验其萌芽情况,其纯度和萌芽率均应达到90%以上。灌木种子为林木或绿化种子,其发芽率、纯度、生活力、优良度应不低于相应国家标准规定的种子质量三级要求。本项目草灌种籽配合比详见表-1。草灌种籽配合比表 表-1草种、灌木种配合比比全播种量3.5

15、害物质。为增强草种的附着力,工人沿坡面水平向开挖一定深度的沟槽,沟槽可为种植土停留保持水肥效果。6、进场的水泥、砂、钢筋等原材料需检验合格并经监理验收合格后使用。2)锚杆施工工人按水平间距1m和顺坡间距1m要求进行锚杆定位。锚杆长度分别为0.5m和2m及带钩锚杆1.9m竖排第一排从边沟边缘沿坡面向上1m为第一排孔,锚杆长度为0.5m;从边沟边缘沿坡面向上2m为第二扰孔,锚杆长度为2 m;竖排第二排从边沟边缘沿坡面第向上1m为1.9m锚杆。锚杆的布置依次类推。工人用风钻配5cm的钻头进行成孔,孔深为0.5m与2m最顶部与马路边平行为2m,工人在进行成孔时要保证孔的中线45C垂直于坡面。工人用水将
16、孔内的土冲洗干净,放入的锚固钢筋。主锚杆、辅锚杆锚固筋的端头外露于坡面10cm,带钩铺锚杆锚固筋的端头外露于坡面20cm。工人用机械将M30水泥砂浆灌入孔内,每灌入30cm,用钢筋进行捣实,直到砂浆面到坡面位置。锚杆的作用为增强边坡的抗剪力增强边坡的整体稳定性,减少边坡滑塌的病害。3)机编热镀锌网施工工人自上而下进行机编热镀锌网的施工。机编热镀锌网的顶部埋入坡顶以下15cm,水平方向搭接10cm,边坡两端边缘卷边10cm。底部埋入边沟边缘以下15cm。工人在进行机编热镀锌网施工同时将0.9m辅锚杆锚固钢筋外露端从中间位置回折以便将植被网固定。机编热镀锌网施工后确保坚贴坡面。4)湿润坡面坡面在喷
17、播前需充分洒水1-2次保持坡面湿润,渗透深度不得小于15cm,待土壤“收汗”后进行喷播。5)测量控制客土喷播施工(1)桩号与面积以及用土量与材料复核。(2)工人首先将车载水浆机开至合适的位置,然后将装载机开在喷射机附近,确保卸料时直接进入喷射机的料斗。工人在土场将土壤挖碎,并过20mm的筛子,防止大颗粒进入水浆喷播机造成堵管现象发生。工人利用自卸车将筛选好的土壤运至施工地点,卸载彩条布上,防止污染路面层。工人利用铲车将土壤铲入水浆喷播机机的料斗,同时放入草籽、有机肥、速效肥、长效肥、泥浆土和黏合剂。加土前先用水车将水浆喷播机加入8m3水每车。土壤配合比(质量)土有机肥泥炭土速效肥长效肥保水剂粘
18、合剂水6410.000.20.20.30.325水浆喷播机将喷射混合材料装入水浆机内搅拌均匀。最后起动喷射机离合器。喷射手打开倒顺阀自上而下进行客土的喷播作业。喷射手根据喷射机的压力挡位和坡面的地质情况选择合理的喷射角度和喷射距离,保证客土能够粘在坡面上不离不散。分3次喷射作业,先2次喷射基层7-9cm不含种子混合土壤,再喷射表层1-3cm含种子混合土壤。苗木:选购符合要求、健壮无病虫害的苗木。杉木宜采用1年生以上播种苗,要求苗高30cm;马尾松采用2年以上播种苗,要求苗高100cm;杜鹃要求采用1年生以上扦插苗,要求苗高30cm;山茶宜采用2年以上嫁接苗,要求苗高30cm。6)养护喷播后及进
