Construction and waterproofing method for top plate cofferdam of comprehensive pipe gallery in river-crossing section
The invention relates to a river-crossing section comprehensive pipe gallery roof cofferdam construction and waterproof method. The method comprises the following steps that before first-stage pipe gallery construction, a river blocking cofferdam and a river-following cofferdam are constructed at first; after construction of the first-stage pipe gallery is completed and before backfilling, a pine cofferdam is constructed on a top plate of the first-stage pipe gallery; waterproof coiled material waterproof construction is conducted on the pine cofferdam; first-stage backfilling is conducted, and a second-stage cofferdam is constructed. According to the river-crossing section comprehensive pipe gallery roof cofferdam construction and waterproof method, the pine cofferdam is constructed after the first-stage pipe gallery construction is completed and before backfilling is conducted, and the problems that in a conventional construction process, the driving perpendicularity of pine piles is not well controlled, or the pile heads of the pine piles are uneven, and the construction efficiency is poor are solved. Or large pores are formed between the pile bottom and the pipe gallery top plate due to improper control of the driving elevation of the pine pile. In addition, waterproof treatment is conducted on the pine piles and the top of the pipe gallery, and river water and underground water are prevented from permeating into one side of the second-stage construction pipe gallery from the joint position of the pine piles and the pipe gallery top plate.
本发明涉及一种跨河段综合管廊顶板围堰施工及防水方法，包括如下步骤：一期管廊施工前先施工拦河和顺河围堰；一期管廊施工完成后、回填前，在一期管廊顶板上施工松木围堰；在松木围堰上进行防水卷材防水施工；一期回填，并施工二期围堰。本发明提供的跨河段综合管廊顶板围堰施工及防水方法，在一期管廊施工完成后、回填前施工松木围堰，避免了常规的施工工艺中松木桩的打入垂直度控制不好，或松木桩桩头不平，或松木桩打入的标高控制不当造成桩底与管廊顶板有较大孔隙问题的发生。而且，在松木桩及管廊顶部做防水处理，避免了河水及地下水从松木桩与管廊顶板接缝位置渗入二期施工管廊一侧。
