Construction method for canal penetration drainage of underground utility pipe gallery
The invention provides a construction method for canal penetration drainage of an underground utility pipe gallery. The construction method is characterized by comprising the following steps of S1, carrying out foundation pit supporting, specifically, arranging a plurality of pouring piles on two sides of a pipe gallery foundation pit from inside to outside, externally coating each pouring pile with a high-pressure jet grouting pile, and pouring a crown beam to the top of each pouring pile; S2, carrying out steel guide pipe and Bailey truss supporting system construction, specifically, constructing a water passing steel guide pipe and a Bailey truss support on parallel positions on an original canal passing position of the foundation pit; and S3, carrying out canal channel flow guide, specifically, extending and constructing a flow guide canal from two ends of the water passing steel guide pipe, favorably making a drainage butt joint and water prevention measure of the flow guide canaland the water passing steel guide pipe, then, after a water passing steel guide pipe and flow guide canal water injection experiment is qualified, draining an original canal to the flow guide canal and the water passing steel guide pipe, and then, blocking the two ends of the original canal so as to realize the safe flow guidance of the canal. A drainage steel pipe of the invention is supported by a Bailey truss, carrying capacity is high, a plurality of pipelines can be carried to simultaneously realize water passing, a drainage device is integrally stable to operate, and a good constructionenvironment is provided for lower pipe gallery construction.
本发明提供一种地下综合管廊穿河渠引流的施工方法，其特征在于，包括如下步骤：步骤1、基坑支护：在管廊基坑两侧由内向外设置若干灌注桩，灌注桩外包裹高压旋喷桩，灌注桩顶部浇筑冠梁；步骤2、钢导管和贝雷架支撑体系施工：在基坑过原河渠处平行位置修建过水钢导管及贝雷架支撑；步骤3、渠道导流：在过水钢导管两端延长修建导流渠，并做好导流渠与过水钢导管的引流对接及隔水措施，然后待过水钢导管、导流渠注水试验通过后将原河渠引流至导流渠和过水钢导管，然后封堵原河渠两端，从而实现河渠安全导流。本发明引流钢导管由贝雷架支撑，承载能力强，可以承载多根管道同时通水，引流装置整体作业稳定，为下部管廊施工提供良好的施工环境。
