CN206468360U 一种隧道管棚测斜管的埋设和居中固定装置 失效 - 权利终止

一种隧道管棚测斜管的埋设和居中固定装置
摘要：
本实用新型涉及一种隧道管棚测斜管的埋设和居中固定装置，包括能够套接在测斜管的定位环，定位环的外圆周上均匀设置若干个支承部，支承部的外端设置滚珠；在测斜管和定位环安装到管棚管内时，滚珠与管棚管之间为间隙配合。本实用新型中通过安装定位环和支承部，支承部上的滚珠和管棚管之间为间隙配合，能够使测斜管中心与管棚管中心重合，保证测斜管埋设质量，增加其测量精度；同时支承部上的滚珠将测斜管与管棚管之间的滑动摩擦变为滚动摩擦，有利于测斜管的埋设。
摘要（英）：

The utility model relates to a bury underground and fixing device placed in middle of tunnel tube canopy deviational survey pipe, including cup jointing the holding ring at the deviational survey pipe, evenly set up a plurality of support on the outer circumference of holding ring, the outer end of support sets up the ball, install tub canopy when intraductal at deviational survey pipe and holding ring, the ball with manage the canopy and be clearance fit between managing. The utility model discloses in through installation holding ring and support, be clearance fit between ball on the support and the pipe canopy pipe, can make deviational survey pipe center and the pipe canopy pipe center coincide, the quality is buried underground to assurance deviational survey pipe, increases its measurement accuracy, sliding friction between deviational survey guan yuguan canopy is managed to ball on the support simultaneously becomes rolling friction, is favorable to burying underground of deviational survey pipe.
