Soft ground structures using the pile and for improving the block forming process

摘要

The present invention is an earthquake in the country was a severe earthquake damage to a relatively recent situation is very harsh measures and research on earthquakes compared to the damage is severe in Japan and abroad.; In the early stages, etc. earthquake seismic measures and for that reason, the guidelines for the structure and direction of social infrastructure established in recent years, but it increased interest in the seismic measures can also be said of the recent trend.; On the other hand, the study of seismic have been made such as harbor structures did not at all consider for earthquake until now, the present invention is possible to needs and cost reduction, shortening, and other environmental pollution for more constructive strong port facilities against earthquakes It can be suppressed, and using for the pile block and improving durability or the like combined with a strong structure the earthquake is a method for the offshore construction of soft ground structure.; In order to accomplish the above object, the present invention is above according, to the center for improved block having a predetermined shape with an opening towards the middle of the black vertical from the block bottom, the head of the pile in forming the structures on soft ground, such as harbor or river inserting a ball that can be fixed through the block for improved is formed, inserted completely through the top from the bottom of the block body for improvement in applications that can be inserted into the pile in the interior of the vertical wall forming the body for improving the block in the vertical and that the ball is formed with a plurality of its features.; Forming parts of the installation space for improvement in this block can be installed to the dredge a predetermined depth on the soft ground, the upper surface in order to achieve the above object, and; Step of pre-calculated soft floor space portion position and distance become a block for improved installation in the horizontal direction of the ground through the soft ground by a pile embedment to a firm state and anti; Step of the insertion hole formed in the center for improved block to be fixed to a mounting block for improvement over the head of the fixing peg mounted on the head of the pile and; Pile and projecting on the upper surface of the modifying block for the solid piles necessary to sequentially laminating a block for improving the ground for supporting only the vertical load for improved through the insertion hole to vertical penetrating in the bottom and the top for improved block block embedment to and the step of; The step of integrating the liquid phase and for the pile and the improvement over the agent inlet block through the vertical to the upper block for improving at one side portion of the improved insertion slot for a peg inserted ball and parallel to the upper surface of the block-mounted form and the block for the: ambient improved block for measures for laying the like riprap or the day after the dredging area unit; It will on soft ground structure forming method characterized by the steps of forming a structure by sequentially depositing a block for addition to a peg projecting above the upper surface of the block for improved.
