[0002] Manually dug bored pile, an engineering term, refers to reinforced concrete piles that are dug by manpower and cast on site. Manually dug bored piles are generally thicker in diameter, and the thinnest is more than 800 mm. They can support structural entities with fewer floors and greater pressure. They are widely used. A pedestal is set on the pile, and then tied and connected with a pedestal beam to make the force of each pile evenly distributed to support the entire building. Manually dug bored piles refer to piles that are made by manually digging holes, then placing steel cages, and pouring concrete.

[0003] In actual projects, after the pile foundation drilling is completed, it is often necessary to carry out cement slurry testing, measure the hole depth and other pre-hole operations, and then lift the steel cage and pour concrete. However, there is a gap period when the hole is open during this process. If it is not protected, there will be a major safety hazard or even an accident.
