Construction technology of river embankment reinforcement project based on steel cofferdam diversion pipe

河道堤防断面水流速较低,易出现水流拥塞现象,造成对坝体安全的威胁。本文提出基于钢围堰导流管的河道堤防加固工程施工技术,获取钢围堰导流管在河道堤防加固工程中的相关施工参数,确定钢围堰导流管的管径,选择合适导流管;获取钢围堰导流管的受力情况,通过平衡受力固定钢围堰导流管;计算钢围堰导流管的导流能力;获取参数后对钢围堰导流管的上下游高程进行确定,实现河道堤坝加固;复核钢围堰导流管的高程真空度,保障施工安全。在相关数据明确的情况下对钢围堰导流管进行安装,完成河道堤防加固施工。选取某水库进行实例应用,监测堤防断面平均水流速,本文加固技术较其他加固技术高55.92T/H,验证本文所提技术的加固效果更好。

The water flow rate of river embankment section is low,which is easy to appear the phenomenon of flow congestion,causing a threat to the dam body safety.This paper presents the construction technology of river embankment reinforcement based on steel cofferdam diversion pipe.The construction procedure is to obtain the relevant construction parameters of steel cofferdam diversion pipe in river embankment reinforcement engineering,determine the pipe diameter of steel cofferdam diversion pipe,and select the appropriate diversion pipe.The force of steel cofferdam diversion tube was obtained,and the steel cofferdam diversion tube was fixed by balancing force,calculating the diversion capacity of steel cofferdam diversion pipe.After obtaining the parameters,the upper and lower elevations of steel cofferdam diversion pipe are determined to realize the purpose of river embankment reinforcement,to check the height vacuum of steel cofferdam diversion pipe to ensure the construction safety.When the relevant data is clear,the steel cofferdam diversion pipe is installed to complete the river embankment reinforcement construction.A reservoir was selected as an example to monitor the average water velocity of the embankment section.The reinforcement technology in this paper is 55.92T/H higher than other reinforcement technologies,which verifies that the reinforcement effect of the technology proposed in this paper is better.
