DRAINAGE STRUCTURE FOR SOFT GROUND TREATMENT AND DEHYDRATION METHOD

摘要

The present invention relates to a pore water drainage structure and drainage method of soft ground, the purpose of which is economical by laying a general soil on the top of the soft ground so as to smoothly drain the gap water dewatered to the ground through the vertical drainage installed in soft ground This very excellent, and after forming the drainage in the general earth and sand drainage pipe connected to the vertical drainage in the drainage to discharge the gap water out of the area is excellent in the horizontal drainage capacity of the gap water, the catchment manhole inside the reclaimed soil It is provided to be buried to facilitate the movement of equipment and to provide a pore water drainage structure and drainage method of the soft ground to prevent consolidation settlement around the manhole.;The present invention for achieving the above object is a general soil laying on top of the soft ground; Vertical drainage is poured into the soft ground through the general soil, arranged in parallel to each other or staggered to form a plurality of array lines and the end of the vertical drainage to extend to the top of the general soil; A series multiplier formed between the pair of array lines facing each other of the array lines; A parallel drainage formed to connect the vertical drainage adjacent to both sides of the series drainage and the series drainage; A drain pipe continuously connected to the series and parallel drains; A water collecting main pipe connected to the drain pipe and collecting the water of the gap; and a water collecting manhole connected to the water collecting pipe to store the gap water and having an upper portion sealed; A discharge and drain pipe installed to extend from the water collecting manhole to the water draining side hole to drain the gap water stored in the water collecting manhole; A buried layer disposed in the parallel and series drainage channels to protect the drain pipe; The technical gist of the present invention consists of a reusable soil layer laminated to cover the collecting manhole on the top of the general soil.;Soft ground, vertical drainage, drainpipe, drainage, catchment manhole, horizontal drainage, channel,
