Concrete Pile Placer with Self-Adjustable Mixing Width

Abstract

The invention discloses a cast-in-place concrete pile pouring device capable of automatically adjusting the stirring width. A discharging hole is formed in the side wall of the lower part of a cast-in-place pipe; the bottom of the cast-in-place pipe is connected with a compacting device; the compacting device comprises an upper-layer stirring device, a middle-layer transmission structure and a bottom-layer stirring device which are arranged in sequence from top to bottom; the upper-layer stirring device and the bottom-layer stirring device are driven by the middle-layer transmission structure to rotate in the same direction or in opposite directions; the upper-layer stirring device and the bottom-layer stirring device can be used for automatically adjusting the stretching-out length of a stirring column according to a pile pore diameter so that the cast-in-place concrete pile pouring device is applicable to a cast-in-place pile with a changeable pile diameter; the compacting device can be lifted or fall off along the cast-in-place pipe and is convenient to use; the cast-in-place pipe is directly and fixedly connected with a motor fixing frame in the middle-layer transmission structure so that each connection rod does not need to be directly connected with the motor and the effect of protecting the motor is realized. When the compacting device is protected by a limiting sleeve to be transferred to a lower place, the compacting device is clamped into a steel bar cage so that the service life of the compacting device is effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a pouring concrete pouring device capable of self-adjusting the mixing width. Background technique [0002] The cast-in-situ concrete pile is a kind of pile formed by directly forming a hole on the spot pile position, and then pouring concrete in the hole or placing a steel cage and then pouring concrete. The characteristic is that the pile diameter can be selected according to the needs, and piles with a diameter much larger than that of prefabricated piles can be built. Compared with the hammering method in sinking piles, the construction noise and vibration are much smaller, and it can be applied to various foundations. There are generally two types of existing concrete cast-in-place piles: immersed tube cast-in-place piles and bored cast-in-place piles. Among them, immersed tube cast-in-place piles use hammering pile sinking equipment to sink tubes and pull out tube...

Problems solved by technology

However, the concrete pouring piles that adopt the drilling process also have their defects: the quality of the concrete pouring has a great influence on the bearing capacity of the piles. If air bubbles appear in the pouring process, honeycombs will be formed on the pile body, and these honeycombs will seriously reduce the bearing capacity of the piles. carrying capacity

However, in the existing technology, the concrete with a relatively large slump is only used to form a pile by its own weight, and the pile body is not compacted by techniques such as vibration and mixing. This is because the vibration and mixing of concrete pouring piles have objective difficulties. First of all, the pile length of cast-in-situ piles is generally more than ten meters to tens of meters, and the vibrating rod cannot reach such a deep depth at all. If the condition is inside, it is difficult to vibrate and the effect is not good
