It is 4km from the seat of town government and 15Km from the city center! It is a small multipurpose reservoir with the main objective of irrigation as well as food control and farming. The rainwater collection area of 15 square kilometers,the largest storage capacity of million cubic meters and the designing irrigation area of 1, 700 mu.Main dam foundation posed of limestone and shale,the rock shaped as weathering,has a lot of of fracture,mainly in pressive tectonic regime, the fussured connection is good, but the seepage on dam foundation still happened. In consideration of the above situation, the departments concerned decided to make high pressure jet grouting and curtain grouting to the dam body and dam foundation respectively. The design of Grouting will be made by Guangxi Technical College of water Resources and Electric Engineering. Our pany won the bid and will responsible for the construction.Key words: Small ( 1) reservoir。 Grouting design。水庫壩址以上集雨面積15km2,總庫容330萬m3,設(shè)計灌溉1700畝。壩體為粘士壩,材料就地取材,主要來源于近壩的粘性士(全風化砂巖和頁巖),其間夾較多的風化巖碎塊,密實度一般,兼之年長日久,壩體出現(xiàn)滲漏比較嚴重。灌漿設(shè)計由廣西水利電力技術(shù)職業(yè)學院承擔,我單位中標并負責施工。(2)那標水庫施工招標文件。(4)《水工建筑物水泥灌漿施工技術(shù)規(guī)范》SL62—94。施工用水從水庫里直接抽取。(1)水泥:選用當?shù)厣a(chǎn)的425普通硅酸鹽水泥。(3)摻合料和外加劑:經(jīng)監(jiān)理人員批準在漿液中加入摻合料和外加劑,各種摻合料和外加劑符合SL62—94和DL5200—2004的要求,加入量通過試驗確定,試驗成果報送監(jiān)理。水泥漿的配制:根據(jù)水灰比,在攪拌桶內(nèi)加入定量的水,然后按水灰比加入相當重量的水泥,攪拌均勻即可。鉆
