The invention discloses a method for supporting a foundation pit on the lower portion of an existing comprehensive pipe gallery, and belongs to the technical field of box culvert construction.The method for supporting the foundation pit on the lower portion of the existing comprehensive pipe gallery comprises the comprehensive pipe gallery, the two sides of the comprehensive pipe gallery are each provided with two working wells, and pipe roofs are arranged between the two corresponding working wells; the two ends of the pipe roofing extend into the corresponding working wells respectively and are provided with connecting lock catches, and a plurality of horizontal angle braces are arranged between the periphery of the pipe roofing and one side of the corresponding working well. The top, the bottom and the lateral direction have the effects of preventing collapse, resisting lateral water and soil pressure and resisting upheaval of a soil body at the bottom of a foundation pit correspondingly, meanwhile, the supporting strength of the foundation pit on the lower portion of the existing comprehensive pipe gallery can be greatly improved through matched use of the bearing frame and the supporting cross beam, and box culvert construction is safer and more reliable.
本发明公开了在既有综合管廊下部的基坑支护方法，属于箱涵施工技术领域，在既有综合管廊下部的基坑支护方法，包括综合管廊，所述综合管廊的两侧均设置有两个工作井，且对应的两个工作井之间设置有管幕，所述管幕的两端分别延伸至对应的工作井内部并设置有连接锁扣，所述管幕的外周与对应的工作井一侧之间设置有多个水平角撑，它可以通过在基坑侧向设置Z字形管幕以作为现浇箱涵的初期支护，对于顶部、底部以及侧向分别起到防塌陷、抵抗侧向水土压力以及抵抗基坑底部土体的隆起，同时利用承重架以及支撑横梁的配合使用可以大大提高对既有综合管廊下部基坑支护强度，使得对箱涵施工更加安全可靠。
