隧道排水结构

Tunnel draining structure

Abstract

The utility model provides a tunnel draining structure. The tunnel draining structure comprises a longitudinal draining pipe, a transverse draining pipe and a center draining pipe, wherein the longitudinal draining pipe, the transverse draining pipe and the center draining pipe are sequentially connected. Diameter expanding of the transverse draining pipe is started from the position away from the center draining pipe about thirty centimeter to the position where the transverse draining pipe is connected with the center draining pipe, and the diameter expanding angle ranges from 5-25 degrees. The tunnel draining structure is simple and reasonable in structure, the force bearing area can be changed by changing the cross section area of water flow, the purpose of increasing pressure is achieved, the increased pressure acts on crystals, the crystals can finally disengage from the inner wall of a pipeline, and the tunnel draining structure is suitable for application and popularization.
本实用新型提供的隧道排水结构,包括依次连接的纵向排水管、横向排水管及中心排水管,所述横向排水管从距中心排水管三十厘米处开始扩径至中心排水管连接,扩径角度为5-25度。本实用新型结构简单、合理,通过改变水流的横截面积,即改变受力面积,达到增大压力目的,增大的压力作用在结晶体上,最终使结晶物脱离管道内壁,适宜推广应用。
