Description

The present invention takes up the technical field of cleaning the inside of a casing, and specifically, is an equipment for removing earth and sand inside a casing for construction.

Concrete piles are widely used in building foundation work. In order to enhance the connection effect between the pile and the support layer, the pile must be made of reinforced concrete with an altitude of 2 to 4 meters. One of the pile construction methods is to press-fit the foundation casing that supports the structure into the ground with a hydraulic jack while repeatedly rotating it, and then excavate the earth and sand that has fallen into the casing and discharge it so that it can be grabbed. After reaching the support layer, a reinforcing bar cage is inserted, concrete is cast while pulling out the casing, and a pile is formed. As mentioned above, it is necessary to remove the sediment that has fallen into the casing before placing the concrete, and as a means, the sediment is generally removed manually, but this method is inefficient and the work is difficult when the depth is deep. It becomes difficult and the earth and sand can be removed spirally by the conventional open technology, but the centrifugal force due to the high-speed rotation of the central axis causes the earth and sand to scatter and cause air pollution. The present invention is an apparatus capable of solving the above problems.
