求翻译：超前小导管外插角按设计施工，与线路中线方向大致成一定角度布置。孔位钻设偏差不超过10cm，孔眼长大于小导管长，钢管顶入长度不小于管长的90％,并用高压风将钢管中的砂石吹出。水泥浆液水灰比和注浆压力严格按照施工规范和图纸设计要求进行施工。是什么意思？

Advanced Small Pipe the outside Chajiao press design and construction, and line center line direction is roughly the arrangement of a certain angle. Hole drilling set the deviation does not exceed 10cm hole is larger than the length of small pipe, steel pipe into the length of not less than 90% of t

Early small tube plug-in design and construction, with the line line direction to point roughly furnished. Holes are drilled with bias is not more than 10 CM, and hole up in a small catheter into the top tube length, length is not less than 90% of the length of tube and pipe with high pressure air t

The ductule extrapolates in advance the angle according to the design construction, the logical circuit median line direction becomes certain angle arrangement approximately.Kong Weizuan supposes the deviation not to surpass 10cm, the perforation coarsening is long in the ductule, the steel crown en

Design and construction of advanced small pipe plug point also press, broadly angled arrangement with the central line direction. Hole drill based deviation does not exceed 10cm, perforations long is larger than the small pipe long, tube top into the length is not less than 90% of pipe length, grave
