Abstract: To solve the construction difficulties of the rectangular pipe jacking in the boulder area in a complex geological environment, based on the pipe jacking project of the pedestrian passage of the Qieye Ridge in the transformation project of the Harbor Avenue in Xiangzhou District, Zhuhai City, Guangdong Province, the construction risks encountered by boulders during pipe jacking excavation were analyzed in conjunction with the actual engineering conditions. According to the size, shape, and distribution of the boulders, the advantages and disadvantages of different construction schemes when encountering boulders during pipe jacking construction process were discussed, and the engineering costs, environmental impact, construction difficulty, safety, and applicability of five obstacle handling schemes were systematically compared and analyzed. The best handling method suitable for this case project was selected to achieve the purpose of improving efficiency, reducing costs, and avoiding risks. The case project adopted the pre-treatment construction technology of the down-the-hole hammer in the casing technology to crush and remove the boulders, and successfully restored the pipe jacking excavation construction. This solution could ensure efficient, safe, and orderly clearance work and had excellent application effects.
