深孔鉆桿
英文
long hole rods-
The problem of torque increase and drill fracture during the process of deep well drilling was analyzed, and a safety protection and control technique was introduced, where a torque sensor was fixed between drilling bar and motor axis, while an electromagnetic clutch was fixed in the transmission chain of feed system
摘要對深孔鉆削過程中出現扭矩增大及折斷鉆頭鉆桿問題進行了分析,介紹了一種鉆桿主軸與電機軸的連接中安裝扭矩傳感器,進給系統的傳動鏈中安裝電磁離合器的深孔鉆削安全保護與控制技術。The latest constructing machine and the newest technology were adopted to ensure that the borehole is perpendicular to the rock face of roof and that the depth of borehole and the torsional moment of the anchoring bolt meet the design requirement
採用最新錨桿施工機具及工藝,保證鉆孔垂直於頂板巖面,孔深及錨桿扭矩滿足新型機械錨桿的設計要求。Under the function of big pressure and dynamic load, the grains may be moved which may cause the soil body distortion. at present, the relatively ripe methods of drill in gravel layer are mostly double - wall drill pipe reverse circulation drilling, auger stem breast wall drilling and down - the - hole hammer follow down drilling
論文根據jsl ? 30型礫石鉆機潛孔錘同心跟管鉆具結構,採用程序計算得到了鉆桿內各深度處壓力分佈、鉆頭壓力降、環形空間壓力分佈及空氣流速分佈。Application yg - 30 construction drilling rig is used for drilling anchor holes in deep base pit of high building, anchor and reinforce side - slope for water conservatory project, water power station project, railways and highways
Yg - 30型工程鉆機適用於高層建築深基坑錨固水電工程鐵路公路錨固護坡,尤其適用於高邊坡治理錨桿孔,排水孔的施工。The extension drill rod which can be used for higher capacity drill, the drill hole can be extended to sezeral meetrs, when drilling the straight hole, the core lifter can help coring
選用加長鉆桿于較大能力的鉆機,可將鉆孔延深至數米,鉆垂直孔時,可採用取芯器配合取芯。Each unit anchor has its own individual tendon, its own unit fixed length of borehole, and is loaded with its own unit stressing jack which ensures that the load in all unit anchors is always identical. the total working load of the anchor is beard by each fixed anchor length of all units in staggered depth in the borehole and by means of respective bearing bodies, the tension loads applied to the plastic coated strands are changed into the compression loads on the grout of each fixed anchor length, then the total working load can be divided into several smaller loads and transmitted to the rock mass and soil in different locations in dispersed compression
壓力分散型錨索是在一個鉆孔中安裝若干個錨索單元,每個單元都有自己的桿體和錨固段,在張拉時分別承受相同的工作荷載;錨索總的錨固力由分散布置於鉆孔不同深度處的這些單元錨索的錨固段來共同承擔,並利用各單元的承載體將無粘結錨索的拉力轉化為對錨固段注漿體的壓力,從而將錨索總的錨固力以壓力形式分散作用於不同深度的巖土體上。分享友人
