Abstract

The present utility model discloses a special ring for underfloor duct comprising a drill part and a drive part. The drill part and drive part are disposed in the front, rear pipe cavities having coaxial line respectively; the drive part disposed in the rear pipe cavity is a power shaft connecting with the power source via an universal coupling, the power shaft extends into the front pipe cavity; the drill part disposed in the front pipe cavity includes a V-shaped drill mounted at the power shaft end part and a plurality drills with spout holes uniformly distributed along internal circumference surface. The drill rod of the drill extends into the rear pipe cavity and engages with the power shaft via gear; a suction pipe connecting with a suction pump is provided in the front pipe cavity. The utility model has an advantage of no destruction to ground surface when laying underground pipelines as well as mass manpower and material resources saving.
本实用新型公开了一种地下管道专用顶管,包括钻体部分和驱动部分,所述钻体部分和驱动部分分别设置在具有同轴线的前、后两管腔内;设置在后管腔内的驱动部分为通过万向联轴器与动力源相联接的动力轴,所述动力轴延伸至所述前管腔内;设置在前管腔内的钻体部分为安装在所述动力轴端部分的V形钻头,和沿前管腔内周面均布设置的多个带有喷水孔的钻头,该钻头的钻杆延伸至后管腔内并通过齿轮与动力轴相啮合;在前管腔内设置有与抽水泵相连的抽水管。本实用新型的优点在于实现铺设地下管道时不破坏地表面,同时节省大量的人力物力。
