Description

TECHNICAL FIELD

[0002] In the pile foundation construction process, the protection layer cushion block is mainly used to ensure the thickness and perpendicularity of the base pile reinforcement cage protection layer, and is usually installed on the side wall of the base pile reinforcement cage. However, when the position of the base pile reinforcement cage needs to be adjusted after being lowered, it is extremely difficult to directly twist and adjust the base pile reinforcement cage because the bottom reinforcement directly contacts the bottom of the pile hole. First, the reinforcement cage needs to be lifted again, then the position of the reinforcement cage is adjusted, and finally the reinforcement cage is lowered again. At the same time, because the traditional protection layer cushion block is usually made of ordinary concrete or ordinary mortar, the strength is low, and the cushion block is broken and falls off due to collision with the pile hole wall during the lowering and position adjustment of the reinforcement cage, thereby affecting the construction quality.

[0003] Therefore, it is urgent to develop a high-strength protection layer cushion block that is not easy to break, can ensure that the thickness and perpendicularity of the reinforcement cage protection layer meet the design requirements, can improve the pile foundation construction quality, and is convenient for position adjustment of the base pile reinforcement cage, thereby reducing the adjustment difficulty of the base pile reinforcement cage.
