1、國(guó)家安全生產(chǎn)監(jiān)督管理局辦公樓抗震加固及維修改造工程越南福和閘堰項(xiàng)目植樹施工方案中國(guó)水利水電建設(shè)集團(tuán)國(guó)際工程有限公司越南福和閘堰項(xiàng)目部二O一年九月十五日1、概述及主要工程量越南福和閘堰項(xiàng)目植樹面積49.27公頃。分布于左岸進(jìn)場(chǎng)道路旁邊，業(yè)主管理房周 圍，和土壩下游區(qū)域。2、施工工藝流程及主要施工方法施工工藝流程：表（層）面處理t測(cè)量定位t挖種植穴t樹苗檢查t植樹t養(yǎng)護(hù)。2.1表（層）面處理：需要植樹的部位用推土機(jī)大致推平，鏟除表面的雜草，灌木等影響樹木生長(zhǎng)的雜物。2.2定點(diǎn)放樣測(cè)量人員進(jìn)行定點(diǎn)的放樣，嚴(yán)格按照一公頃面積植樹440棵放樣（即植樹間距4.77 米），測(cè)量后做明顯標(biāo)記。2.3挖種植穴：

2、種植穴直徑60cm深度為60cm要求坑壁光滑，上下面口徑基本一致。2.4樹苗檢查樹干挺直，沒有明顯彎曲，無蛀干害蟲和未愈合的機(jī)械損傷；樹冠豐滿，枝條分布 均勻、無嚴(yán)重病蟲危害，樹葉正常；根系發(fā)育良好、無嚴(yán)重病蟲危害；土球大小為苗木 胸徑的10倍以上。2.5植樹2.5.1種植的質(zhì)量標(biāo)準(zhǔn)：種植的苗木品種為景觀樹柚樹，苗木的本身與地面垂直，沒有傾斜；嚴(yán)格按照測(cè)量定點(diǎn)種植，橫平豎直，樹木應(yīng)在一條直線上；樹苗高度為1.5米左右，相鄰兩株高差不超過30cm種植深淺與原土痕持平；保持樹苗土球完好，包裝物應(yīng)取出。2.5.2種植的程序和方法：樹木入穴后，土球放穩(wěn)，樹干直立，拆除并取出包裝物；種植后在樹木四周筑成

3、高5- 10cm的灌水土堰，方便澆水；種植后需要支撐的樹木，用樹枝或者竹竿支撐牢固， 使樹木保持直立；新植樹木 24小時(shí)內(nèi)澆第一遍水，三日內(nèi)澆第二遍水，十日內(nèi)澆上第 三遍水，三遍水后轉(zhuǎn)入后期養(yǎng)護(hù)；每次澆水后均整堰、堵漏、培土、扶直樹干，第三遍 水后封堰。2.6養(yǎng)護(hù)：新植樹苗完成后進(jìn)行養(yǎng)護(hù)，主要項(xiàng)目包括：澆水、防治病蟲、補(bǔ)栽未成活樹苗、直至交付驗(yàn)收。3、施工設(shè)備及人員配置3.1施工設(shè)備序號(hào)機(jī)械設(shè)備名稱規(guī)格型號(hào)單位數(shù)量備注1自卸汽車10t臺(tái)12推土機(jī)SD23臺(tái)13水泵2寸臺(tái)54全站儀PENTAX臺(tái)1R -322NX5水桶/只若干序號(hào)機(jī)械設(shè)備名稱規(guī)格型號(hào)單位數(shù)量備注6鋤頭/把若干7鐵锨/把若干3.2

9、pli ng.2.5 Pla nti ng2.5.1 Quality Stan dard:The category of the sapling to plant is teak as Iandscape trees. The sapling itself should be plated vertically toward the land without any slant. The trees should be planted strictly according to the setting out points, ordered in rows and lines with tre
