Abstract

本发明的围瓮区规避悬河穿河隧道特殊风险方法，属于路桥工程。包括遂道、围堰、围瓮区和路面。其特征是在悬河隧道的两端出口外修筑与河坝等高的围堰，形成封闭的围瓮区。由遂道延伸的路面通过坡道翻越围堰。本发明与现有技术相比，规避了穿河遂道发生透水，对悬河形同决堤的特殊风险，为悬河修筑穿河隧道消除了后顾之忧，提供了实施可能。因而，本发明具有很好的应用价值。

Description

围瓮区规避悬河穿河隧道特殊风险方法
一、技术领域：
本发明涉及路桥工程，具体的说涉及一种围瓮区规避悬河穿河隧道特殊风险方法。
二、背景技术：
穿河隧道以其全天候通行和不影响河面通航及疏洪等优势被广泛应用。但对于河床高出于两岸地平的悬河，则少有实施案例。究其原因，主要是在隧道发生意外透水情况下，一般隧道只造成淹没隧道的局部危害，且事后也易于修复重建。而在悬河隧道，则无疑于决堤，后果极其严重，事后也多无修复可能。
三、发明内容：
本发明的目的是针对以上问题，提供一种局限透水危害风险，便于事后修复的围瓮区规避悬河穿河隧道特殊风险方法。
本发明的目的是通过以下技术方案实现的：
一种围瓮区规避悬河穿河遂道特殊风险方法，包括遂道、围堰、围瓮区和路面，其特征是在悬河穿河遂道的两端出口外修筑与河坝等高的围堰，形成封闭的围瓮区，由遂道延伸的路面通过坡道翻越围堰。
本发明的围瓮区规避悬河穿河隧道特殊风险方法，通过修筑与河坝等高的围堰，将意外透水圈限于围瓮区范围内，通行车辆通过坡道翻越围堰，规避了修筑悬河隧道面临的特殊风险，为实施悬河隧道建设解除了后顾之忧，因而具有很好的实际应用价值。
四、附图说明：
图1为围瓮区规避悬河穿河隧道特殊风险方法的局部纵断面示意图。
图2为围瓮区规避悬河穿河隧道特殊风险方法的局部鸟瞰平面示意图。
图中：1河坝、2河床、3隧道、4围堰、5路面、6围瓮区
五、具体实施方式：
下面结合说明书附图对本发明的围瓮区规避悬河穿河隧道特殊风险方法作进一步详细说明：
如图所示，河床2下修筑隧道3穿越悬河，在隧道3的两个端口外修筑与河坝1等高的围堰4，与河坝1相切形成围瓮区6，在围瓮区6内修筑上坡道，围瓮区6外修筑下坡道，与隧道3延伸的路面5连接，形成翻越围堰4，穿越隧道3的顺畅通道。
除说明书所述的技术特征外，均为本专业技术人员的已知技术。
