Main Construction Method of Anchor （1） 、總體方案 Scheme錨桿施工與邊坡開挖施工同步進(jìn)行，上層邊坡支護(hù)施工完成，開挖至預(yù)應(yīng)力錨桿施工位置后，及時(shí)組織進(jìn)行腰梁及預(yù)應(yīng)力錨桿施工，完成邊坡防護(hù)，減少邊坡暴露時(shí)間。3. Report of Geological Engineering Exploration for proposed Water Treatment Plant and onthespot investigation for the surrounding environment of said construction site.中國現(xiàn)行國家標(biāo)準(zhǔn)、施工技術(shù)規(guī)范、規(guī)程、質(zhì)量檢驗(yàn)評定標(biāo)準(zhǔn)及驗(yàn)收方法、安全檢測標(biāo)準(zhǔn)及技術(shù)規(guī)程、文明施工要求等。 shall be selected in line with the operative norm of GB/T specification of anchor has two types including 3162。 Adopt airdriven downhole hammer for anchor hole construction to effectively avoid the erosion of the slope. Fasten the construction speed. Adopt type 868 Youbolin anchorage drilling rig for anchor hole construction. The diameter of the anchor hole is about φ150mm, the designed depth of the anchor hole is 58m, 25 degree boreforming with horizontal angle.、錨孔鉆孔技術(shù)參數(shù)根據(jù)所鉆部位孔內(nèi)地層情況確定。鉆孔過程中對每個(gè)孔的地層變化，鉆孔狀態(tài)(鉆壓、鉆速)、地下水及一些特殊情況作好現(xiàn)場施工記錄。After drilling to designed depth, drilling work cannot be stopped immediately and keep drilling 12mimutes to avoid insufficient size of hole and not up to the designed hole diameter. Any dregs and water cannot be attached on hole wall and must be cleaned out of hole. After drilling, blow the rock powder and water out from hole with highpressure air (～). Except for anchorage of integrity and hard rock , the rest anchor holes cannot be washed by highpressure water. If the confined water flew from anchor hole, anchorage and grouting could be carried out after water pressure and volume reduced, and set up drainage hole in suitable place if necessary. If it is required to deal with impounded water in anchor hole, grouting closure and secondary drilling will be adopted. ⑤、錨孔檢驗(yàn)⑤ Anchor Hole Test錨孔鉆孔結(jié)束后，須經(jīng)CMEC工程師檢驗(yàn)合格后，方可進(jìn)行下道工序。to ensure the protective layer thickness of anchor body is not less than 2cm. Manpower shall be adopted for anchor body installation. It shall be checked seriously for anchor hole serial number before use highpressure air to blow the hole after confirmed. Slowly put the anchor body into hole,use steel tape to measure the steel strand length outside the hole and calculate the inside hole anchor length(deviation controlled within 50mm) to ensure the anchorage length. 首先按照設(shè)計(jì)要求長度切割鋼絞線，用冷彎機(jī)將無粘結(jié)鋼絞線彎曲成U型并固定在承載體上，然后按設(shè)計(jì)荷載體間距組裝完成整個(gè)錨桿體。 Normally, the actual consumption of grouting is more than theoretical volume. The grouting is pleted as the exhaust vent stops vent and the excessive grout is over flow from the exhaust vent mouth. If insufficient grouting or sedimentation after grouting, supplementary grouting shall be needed till the totally full of the grouting. To clean the grouting pipes, grouting guns, sleeves and make accurate, plete, clear grouting records after pleting grouting.、錨桿腰梁的施工 Construction of Intermediate Beam of Anchor腰梁采用C30混凝土現(xiàn)場整體澆注，OVM15錨具與其同時(shí)安裝澆筑固定。 Before tension, inspection must be done to ensure the bearing face of the anchor angle bracket pedestal must be smooth and even, vertical to the axial line of anchoring rods. If not, relevant rectifying works shall be done.、張拉施工前必須對張拉機(jī)具和儀器儀表進(jìn)行標(biāo)定和調(diào)試校準(zhǔn)。第二次注漿再次向錨固區(qū)高壓注漿，~，注漿壓力為2～，. M25 grout of cement is used as anchor grouting material. Firstly grout from the hole bottom outwards to the anchorage section with the cementsand ratio of 1:, watercement ratio of , grouting pressure of . Secondly grout with high pressure to the anchorage section with neat cement grout of watercement ratio of , grouting pressure of , and the termination grouting pressure shall not less than .、當(dāng)孔口出現(xiàn)溢漿且持續(xù)時(shí)間不低于5min后(或排氣管停止排氣),方可停止注漿，注漿完畢后待砂漿凝固收縮后，空口進(jìn)行補(bǔ)漿。Control drilling speed according to geological condition. Drilling work shall be stopped in time when the obstacles or abnormal conditions occurred and take corresponding measures as soon as possible after checking. Drilling depth is 200mm greater than the designed anchor length.、錨桿采購及安裝 Anchor Purchase and Installation 預(yù)應(yīng)力錨桿體由腰梁、自由段、錨固段和安全段四部分組成。為確保錨孔
