北京通州运河核心区市政配套工程东关大道地下隧道下穿通惠河段,针对隧道下穿河流施工难度大、安全风险高的特点,采取围堰筑坝对河流进行导流,该法取材容易,施工速度快,拆除方便且造价低,实施效果良好。
The Dongguan Avenue underground tunnel which is a mumclpal supporung project located in Tongzhou Canal Core Area of Beijing passes through the Tonghui River. Considering huge difficulty and high safety risk in tunnel construction passing through river, cofferdam was built for river diversion, because this method involves common construction material, fast construction, convenient dismantlement, low cost and favorable construction effect.
