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。 The second tributary。 Grouting design。 Zuojiang River目 次摘 要 IAbstract II1 工程概況 12 庫區(qū)地質(zhì)情況 13 施工依據(jù) 14 施工措施 1 1 灌漿材料準(zhǔn)備及制漿 1 1 2 2 2 3 3 3 3 4 5 裂隙沖洗和簡易壓水試 55 施工質(zhì)量保證措施 6 6 6 6 76 施工機械和人員配備 7 7 77高噴防滲板墻的施工 78高壓擺噴灌漿施工的經(jīng)驗 8 8 8 8 9 9 9 9 9 10 10 11 11 13結(jié) 論 14謝 辭 15參考文獻 16 1 工程概況那標(biāo)水庫位于憑祥市夏石鎮(zhèn)夏石社區(qū)那標(biāo)屯西面的左江二級支流上，距夏石鎮(zhèn)政府所在地4km，距憑祥市市區(qū)15km，是一座以灌溉為主，兼顧防洪、養(yǎng)殖等綜合利用的小型水庫。水庫壩址以上集雨面積15km2，總庫容330萬m3，設(shè)計灌溉1700畝。2 庫區(qū)地質(zhì)情況主壩壩基由石灰?guī)r和頁巖組成，巖石多呈中化風(fēng)狀，裂隙較發(fā)育，多以壓扭性為主，裂隙間連通性較好，但仍出現(xiàn)壩基滲漏現(xiàn)象。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(fēng)化砂巖和頁巖)，其間夾較多的風(fēng)化巖碎塊，密實度一般，兼之年長日久，壩
