[0002] Sheet piles, square piles and other piles of other materials or shapes are long and flat in shape and can be used for the protection of low slopes, foundation pits, etc. They are generally driven in by strong tamping. Reinforced concrete piles are a common type of piles used in pile wall support structures. They have the characteristics of simple construction and short on-site operation cycle, and have been widely used in foundation pits.

[0003] In order to facilitate production and processing, combined with the road transportation conditions at the construction site and the limited construction operating space, reinforced concrete precast piles are often used to connect to meet the length of the precast piles required by the design.

[0004] However, when the required protection height is greater than the height of a single pile body A, it is often necessary to stack and connect two or more pile bodies A. The traditional connection adopts pile end plate welding, which requires the use of engineering vehicles to transport construction personnel to the interface position, and the use of welding equipment to weld and fix the two pile bodies A on-site. However, this on-site welding is difficult to accurately control the tightness and verticality of the pile connection, and the welding quality is unstable. Welding is not only time-consuming but also environmentally unfriendly. Utility Model Content
