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？

Advance a small tube outer Gusseted by design and construction, and line the center line direction generally angled layout. Deviation of drill holes located no more than 10cm, the hole grew up in the small pipe length, the length of pipe into the top tube length is not less than 90%, and use high-pr

Small ducts ahead according to the design, construction, plug-and-play corner with centerline direction lines are generally arranged into a certain perspective. Holes are bored hoc deviations holes, not more than 10 cm long, and grew up in the small catheter tube into the length top tube length is n

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
