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)行國家標準、施工技術規(guī)范、規(guī)程、質(zhì)量檢驗評定標準及驗收方法、安全檢測標準及技術規(guī)程、文明施工要求等。The anchor construction shall be performed simultaneously with the slope excavation. After the pletion of supporting construction of upper slope, excavating to the construction location of prestressed anchor, then carrying out the construction of intermediate beam and prestressed anchor and finishing supporting work for slope in order to reduce exposure time of slope. 1) 、準備工作：機具配備質(zhì)量和數(shù)量，人員配置數(shù)量和結(jié)構(gòu)等必須與預應力錨桿施工相適應，滿足施工需要；完成原材料進場及試驗檢測；完成施工技術方案、開工報告等技術資料的編寫、上報和審批，技術交底資料的下發(fā)學習，原材料送檢、報批手續(xù)及資料收集。 Issuing technical information to staff for study。. Length of anchor: its length shall be ～ and the anchorage length shall be 5～ depth that the anchor hacked into the original concrete foundation shall be not less than 1m. 、錨桿入射角度：25度 Injection Degree:25 degree、錨桿直徑：150mm Diameter of anchor:150mm、錨桿：采用鋼絞線162。 shall be selected in line with the operative norm of GB/T specification of anchor has two types including 3162。 執(zhí)行規(guī)范GB500862015。執(zhí)行規(guī)范GB500862015 Anchor plate: The size of anchor plate shall be 300*300*25(mm). The size of round hole located at the center of anchor plate shall be determined according to the round hole of anchorage(with 3 holes). The external diameter of round hole for inserted plate shall be equal to dimension of the margin of anchorage. The size of anchor plate shall be 300*300*25(mm). The size of round hole located at the center of anchor plate shall be determined according to the round hole of anchorage(with 2 holes). The external diameter of round hole for inserted plate shall be equal to dimension of the margin of anchorage. The standard of GB500862015鉆機安裝好后，進行全面質(zhì)量檢查，檢查鉆機方位、傾角、水平度和開孔鉆頭落點差。 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.、錨孔鉆孔技術參數(shù)根據(jù)所鉆部位孔內(nèi)地層情況確定。 Revolving speed: keep medium speed in normal drilling proceed. Keep low speed for the loose soil and broken rock. Appropriately improve the speed for unbroken bedrock.、鉆孔過程中，隨時保證孔內(nèi)排渣暢通，及時排出孔內(nèi)巖渣。Before anchor construction, arrange manpower to modify the slope surface timely from top to bottom layer by layer. When excavated to edge of the filling pile body, excavation height of each layer is equal to the spacing between intermediate beams. Over excavation is strictly controlled. Intermediate beam foundation can be excavated until excavating to the next terrace, and carry out the anchor working. After each slope excavation pleted, if occurred soil slope, it shall be covered by tarpaulin to avoid erosion by rain.、施作錨孔 Anchor Hole Drilling錨孔在腰梁基礎開挖完成，并經(jīng)坡面地質(zhì)條件確定能滿足錨桿施工要求后進行。Based on existing slope surface, position of anchor hole shall be measured and set out exactly and marked by red paint at the construction point according to designed arrangement(see Attachment 1 for details). If uneven slope surface or special geological condition occurred, adjust position of anchor appropriately on premise of getting approval from design unit and ensuring stability of the slope and safety of the structure. Position of anchor holes which have been meas
