[0002] With the development of economy, the pace of modernization of cities is also accelerating. Nowadays, in order to ease the pressure of traffic and meet people's travel needs, more and more cities have begun to pay attention to the role of subway as a means of transportation. In the process of building subway tunnels, pile foundations are constructed when tunnels are excavated. Pile foundations are deep foundations composed of piles and pile caps connected to the top of the piles or single pile foundations connected by columns and pile foundations. If the pile body is completely buried in the soil and the bottom of the cap is in contact with the soil, it is called a low cap pile foundation. If the upper part of the pile body is exposed to the ground and the bottom of the cap is above the ground, it is called a high cap pile foundation. Since the pile foundation is generally excavated deeper, and the tunnel is under construction, the lighting measures therein are not perfect, so the tunnel under construction is often dim, and the depth of the pile foundation in the tunnel is generally more than 10 meters. If no protective measures are set up at the edge of the pile foundation, in a dim environment, the operating personnel and operating vehicles are likely to ignore the existence of the pile foundation, thereby posing a greater safety hazard. Furthermore, personnel in the technical field have proposed a tunnel pile foundation protection device to solve the above problems. Utility Model Content
