During grouting operations, two piles must be used for cyclic grouting. First, perform grouting on the A pipe of the root pile, accounting for 65% of the total grout volume. After finishing, proceed to grout the A pipe of the other pile. Then, grout the B pipes of both the root pile and the second pile, following the aforementioned construction sequence to ensure effective grouting.

Contractors must select the right equipment, such as the mixer drum for mortar and the mortar pump, based on the structural type of prestressed beams, the amount of grout injection, and construction methods, which is crucial for ensuring the grout is filled and compacted properly. The fluidity of the mortar should be appropriate, the expansion and bleeding rates should be moderate, and the strength must meet the design requirements, all of which are prerequisites for ensuring the quality of the mortar.

1. Manufacturing grouting tubes
通常, both the reinforcement cage and grout pipe production must be carried out simultaneously. Iron pipes with a diameter of around 25mm are used for the grout pipe production, with threaded connections and wire for sealing both ends, ensuring the sealing meets construction requirements.

Pile end grouting technology, as an essential part of pile foundation construction in high-rise building projects, directly affects the overall quality of the construction. To effectively enhance the overall quality of high-rise building construction, it is necessary to focus on the following aspects:
