Technical Field [0001] The present invention relates to a slime removal apparatus and method for constructing a large diameter basic file,

The present invention relates to a large-diameter foundation file which can be used to construct a large-diameter foundation file by smoothly removing the slime of the earth or the sea floor by using a water jet, a compressed air and an excavation screw in civil engineering work for a large structure such as a wind turbine, More particularly, the present invention relates to a slime removing apparatus and method for a large-diameter foundation file construction capable of lightening the construction and effectively discharging the slime in the casing to enable perforation of the large diameter. .

In general, the slime removal equipment is used to remove (discharge) the slime at a designated location for construction of foundation piles such as piers or wind generators in the ground or under the sea.

However, conventionally, only the slime for constructing a base file of a certain diameter can be removed, which has a construction limitation that can not construct a large diameter base file required for a large structure such as a wind power generator and a pier.

In particular, since the slime must be removed after excavation using a vibration means such as a vibro hammer in the past, there has been a problem that noise and impact are generated and work efficiency is lowered.

In addition, conventionally, since the slime for constructing the foundation file of the large diameter can not be smoothly removed, the construction period is increased and the application range is limited.

Conventionally, there has been a problem in that it is not possible to construct a large diameter base file having various diameters depending on design specifications.

On the other hand, conventionally, there has been a problem that a smooth slime removing operation can not be performed on a hard ground.

In addition, conventionally, the stirring efficiency of the slime is lowered, and the construction quality of the foundation pile is deteriorated.

In order to solve the above-mentioned conventional problems, the present inventor proposed a slime removing apparatus and method for constructing a large-diameter foundation file of Korean Registered Patent No. B1-1377560 (Mar.

In the case of the above-described prior art, a pedestal is installed at a center so that a casing penetrating the underground or the sea floor is positioned; A plurality of pin piles fixed to the lower portion of the pedestal by penetrating the ground or the sea floor; A work table for resting on the upper end of the casing; A fixing member formed at a lower portion of the work table to fix an upper end of the casing; A discharge hopper installed inside the casing; A discharge pipe installed on the discharge hopper to discharge the slime to the outside; A water jet spraying pipe connected to one side of the upper portion of the discharge hopper and spraying high pressure water into the discharge hopper; A compressed air discharge pipe installed at the other side of the upper portion of the discharge hopper to discharge compressed air into the discharge hopper; A drilling rig is provided so as to be able to move to an upper portion of the work table, a drill is installed in the front of the drilling rig in a vertical direction, a drive member is installed so as to be movable up and down along the drill, And a plurality of water jet nozzles are provided on the outer diameter of the rod.

In the case of the above-mentioned prior art, it is a useful invention that can improve the efficiency and reduce the air shortage due to slime removal.

However, in the case of the prior art, heavy excavation equipment must be seated on the upper side of the pedestal, which requires durability to withstand a fixed amount, and it has been difficult to install or move the equipment due to enlargement of equipment.
