文章简要介绍了一中新的非开挖技术——直铺管法,对于水平定向钻不适宜施工的地层中采用该方法可较好的解决问题。直接铺管法能一道工序完成铺设,节省管道连接时间,相对于定向钻钻孔更小、泥浆用量更少,只需在入土端布置场地,对出土端影响极小,直铺法可根据不同地质更换不同的刀盘,配备二次破碎装置,适用不同地层,可降低地质风险,掘进机可回拖,预防施工意外。 The article briefly introduces a new non-excavation technology-Straight pipe laying method, which can be used to solve the problem in strata that horizontal directional drilling is not suitable for construction. The direct pipelaying method can be completed in one process, saving pipe connection time. Compared with the directional drilling, the drilling hole is smaller and the amount of mud is less, only the placement of the site in the end of the earth has a minimal impact on the end of the excavation. Geological replacement of different cutterhead, equipped with secondary crushing device for different strata, can reduce the geological risk, boring machine can be towed back to prevent construction accidents.
