Description

Concrete conveyor for pile foundation

technical field

The utility model relates to a building construction equipment, more specifically, it relates to a pile foundation concrete conveyor.

Background technique

In construction projects, especially in pouring concrete pile foundation projects, it is often necessary to transport the ready-mixed concrete to the pile hole by car, and then use the lifting bucket to send the concrete into the concrete pouring cylinder, and pour the concrete into the pile hole. After filling a pile hole every time, if there is unused concrete in the concrete vehicle, the vehicle must be moved to the next pile hole to be poured and then poured. When the designed pile holes are more dense, the vehicles loaded with concrete often cannot move to the pile holes to be poured, especially when the construction site is muddy in rainy days, it is more difficult for the vehicles to move, causing inconvenience in construction and even delaying the construction period.

At present, the Chinese patent application number CN02225560.5 discloses a pile foundation concrete conveyor, which is composed of a support, a concrete pump and a concrete delivery pipe. Above, the concrete pump is equipped with a concrete funnel, and an adjustable-length concrete delivery pipe is connected to the output port of the concrete pump. The further design is to provide a locking device and a rolling device between the turntable and the support. When in use, the utility model is installed at a suitable position on the construction site, and the turntable is turned to connect the concrete delivery pipe from the discharge port of the concrete delivery pump to the upper opening of the pouring tube of the pile hole, and then the turntable is fixed for pouring operation.

Although this kind of concrete conveyor can transport concrete, when the workers introduce the concrete into the concrete funnel, a large number of air bubbles will be generated inside the concrete. The air bubbles in the concrete will cause the inside of the concrete to be not dense, thus affecting the quality of the concrete. Strength, therefore, still has room for improvement.
