Description

Equipment and method for placing of drainage material on soft ground improvement

The present invention relates to a soft ground drainage layer installation equipment and installation method, and more specifically, a plurality of transfer units are installed in two upper and lower stages to enable independent operation to ensure a sufficient distance between the drainage layer material installation point and the position of the equipment. The present invention relates to a soft ground drainage installation equipment and a laying method that can minimize heaving due to excellent restraint and sedimentary soil effect by laying a soft ground in one state.

Conventionally, in order to improve the soft ground, a method of laying by Dozer while forcibly replacing with high quality soil such as Santo or taking a heaving has been used.

However, in the case of the forced replacement method, it is necessary to secure a torch for mass supply of high quality soil such as santo, which has a disadvantage in that the economic efficiency is lowered due to environmental destruction, civil complaints, and excessive construction cost due to the incision of the acid. In addition, the method of laying with the doja has a disadvantage in that the application range is limited to a small site because it has to take the hebbing.

Meanwhile, as the necessity of coastal reclamation due to the lack of industrial site, the dredging reclamation using marine clay is made, and the drainage layer laying method using the belt conveyor and The equipment was being developed and used, but it was inefficient because the equipment was too heavy or the distance between the installation point and the equipment was too short.

The present invention has been made in view of the problems described above, to provide a soft ground drainage layer installation equipment and installation method to reduce the ground pressure by expanding the endless track to minimize the impact on the soft ground during operation on the soft ground The purpose.

In addition, the present invention is installed by separating the upper and lower two stages to enable the independent operation of the plurality of transfer parts, by installing a lower transfer portion protruding to a dust point to ensure a sufficient separation distance between the installation point of the drainage layer material and the position of the equipment It is another object to provide a soft ground drainage laying equipment and a laying method capable of laying a soft ground drainage layer in a state.
