<P>PROBLEM TO BE SOLVED: To provide a drainage structure in a well method for levee reinforcement that allows for effective continuous removal of water penetrated in a levee body. <P>SOLUTION: The drainage structure in a well method for levee reinforcement has a catchment block 16a with a water conduction hole 22 located on an external wall that is buried in a foundation ground 12 of a levee body 10 and collects and discharges the water penetrated in a levee body 10 that enters in a catchment block 16a through the water conduction hole 22. The catchment block 16a has a prismatic shape with a cavity and a height shorter than length and consists of an engaging recess 23 on one side and an engaging protrusion 24 on the other side that can be inserted to and engaged with the engaging recess 23. Multiple catchment blocks 16a are connected and arranged in a line in a slot 20 that is dug at certain depth along the levee body 10 on the foundation ground 12 of the levee body 10. A discharge wall 17 is formed by inserting to and engaging the engaging protrusion 24 with the engaging recess 23 on the line of the catchment blocks and stacking up a line of other catchment blocks. <P>COPYRIGHT: (C)2012,JPO&INPIT |
