【正文】 Begin the tension when strength grade of the grout and concrete strength grade of intermediate beam and anchor beam reach 80% of the design strength. After pleting the designed tension, to conduct one pensation tension at proper time and then lock. After pensation tension, to remain 510cm steel strand measuring from the anchorage device and cut the balance part by mechanical method. It is forbidden to cut strand by electric arc. Full fill the spacing between the bearing plates and anchor heads by using concrete paste. At last to seal the anchors by using concrete with degree not less than C30 to prevent rusting.、錨桿張拉前檢查錨斜托臺座的承壓面必須平整，并與錨桿的軸線垂直，不滿足要求時作相應(yīng)處理。如錨桿與豎梁箍筋相干擾，可局部調(diào)整箍筋的間距。Secondary pressure construction process is adopted for the anchoring grouting of this project.、錨桿注漿材料為M25水泥漿，第一次注漿自孔底向外灌注錨固段，灰砂比宜選用1:。制作時注意，鋼絞線不得相互纏繞并保證承載體位于鉆孔中部。鉆孔深度大于錨桿設(shè)計長度200mm?？讖健⒖咨顧z測采用標準鉆桿在CMEC工程師旁站下進行，要求驗孔過程中鉆頭平順推進，不產(chǎn)生沖擊或抖動，鉆具驗送長度滿足設(shè)計錨孔深度，退鉆要求順暢，用高壓風(fēng)吹驗不存明顯飛濺塵碴及水體現(xiàn)象。為確保錨孔直徑，要求實際使用鉆頭直徑不得小于設(shè)計孔徑。如遇地質(zhì)情況與地勘報告不符出現(xiàn)不良鉆孔現(xiàn)象時，須立即停鉆，及時進行孔道固壁灌漿處理(～)，待水泥砂漿初凝后，重新掃孔鉆孔。Anchor hole shall be drilled after pleting foundation excavation of intermediate beam and ensuring that geological condition of slope can meet the requirement of anchor construction.、錨孔測放 Anchor Hole Measure and Setting out根據(jù)實際坡面，先按設(shè)計布置要求，將錨孔位置準確測放在坡面上，并用紅油漆在現(xiàn)場施工部位標明錨桿開孔位置（詳見附圖一）。 The technical parameter of anchor hole is based on the geological condition of the drilled location.、鉆壓：鉆孔過程中，鉆壓保持平穩(wěn)，不得隨意增減壓力。shall be plied with. 、錨桿抗拔：待腰梁施工完畢立即進行養(yǎng)護，且腰梁、錨桿混凝土強度達到80%后才能進行錨桿抗拔實驗檢測； Tensile testing of anchor: The curing work shall be carried out at once after the pletion of intermediate beam construction and the tensile testing of anchor could be conducted after the concrete strength of intermediate beam as well as anchor up to 80%.錨桿檢測實驗按下列規(guī)范進行：The anchor test shall be performed conforming to the following standards:（3） 、錨桿成孔工藝3.
