  Walking style pile driver using electric for underground etaining wall}

     The present invention is a walking pile driver capable of vertical excavation and horizontal excavation by replacing pile drive of conventional caterpillar pile driver and excavation equipment with electric chain digging device to build concrete continuous retaining wall underground. It is located in the electric pneumatic pile driver for the construction of underground retaining walls that can reduce manufacturing costs, facilitate excavation construction, and prevent noise pollution and soot pollution.

     The present invention replaces the existing underground retaining pile driver with an electric walking pile driver of a walking type moving device instead of an endless track, and replaces an excavating equipment with an electric chain drilling device. It is perfectly supported and efficient in construction, and it lowers manufacturing cost and construction cost, and prevents noise pollution and soot pollution caused by excavation by electric power. There is this.

The present invention is a conventional auger drill equipment and chain excavation device as an electric drive and instead of the endless track of the pile driver and a pair of lateral moving walk hood at the bottom of the pile driver body and

A pair of forward and backward walking hoods are installed at the lower part of the pile driver body so that they can be moved by electric drive.The pile driver body is connected to the pair of sideways walking hood and a pair of forward and backward walking hoods. Safely and quickly supports the safety of the electric chain excavation device installed on the leader, so that the excavation can be carried out safely and promptly. The electric pile driver for underground retaining wall construction that can prevent the environmental pollution caused by noise pollution and soot generation.

     The present invention relates to an electric walk type pile driver for constructing an underground retaining wall, and replaces an endless track of an electric drive pile driver installed with an electric drive chain excavation device to reduce the manufacturing cost and construction cost, and to reduce electric power. The present invention provides an electric walking pile driver for building an underground retaining wall to prevent noise complaints and soot pollution caused by excavation and to prevent civil complaints.

     In general, when constructing a high-rise or low-rise building, especially when the foundation for reconstruction, excavate the basement of the building and construct the building from the basement. Install the anti-soil barrier to prevent the flow to the side.

     As an example of an excavation device for constructing a continuous concrete retaining wall for solving the above problems, an excavation chain is provided with a hydraulic motor and a pair of sprockets, and a cutting tooth (excavation rake) scraping soil is formed at regular intervals.
