Definitions

  • the present invention relates to a drain roll package.
  • the present invention relates to a drain roll package suitable for providing continuous drain band for use in ground treatment operations.
  • PVD prefabricated vertical drain
  • Such drain material is typically supplied in a roll form, i.e. a continuous drain band wound around a reel in a single column, with the width of the roll the same as the width of the band.
  • a rig carries an end of the drain band and inserted into a predetermined depth of the ground.
  • the drain roll is unwound to release the drain band which follows the insertion of the drain band into the ground.
  • the leading end of the drain band is fixed inside the ground.
  • the rig is then retracted from the ground, leaving a segment of drain band inside the ground with a length the same as the predetermined depth.
  • the drain band is cut off at a point a certain length above the ground surface to complete the insertion process of this drain band segment. This insertion process is repeated by attaching the end of the next segment of the drain roll to the rig tip and inserting the rig tip into the ground at an adjacent location. When the current drain roll reaches the end, or with a remaining drain band segment of a length shorter than the predetermined depth, the current drain roll will be replaced with a new one and the operation resumed.
  • the drain band insertion operation will be frequently interrupted for drain roll replacement, each time a current drain roll reaches its end of drain band length segment.
  • placement of drain bands in the ground at relatively greater depth is required, e.g. about 60 meters as is the case of land reclamation in some areas.
  • the currently available drain roll package in the market which contains a drain band of about 300 meters, can only last for several insertion operations before a new drain roll is replaced. Frequent replacements of drain rolls are therefore required during which, the insertion option is interrupted which greatly reduces the production efficiency.
  • any remaining segment of a drain band is still wound on the drain roll, it is not always easy, if not impossible, to determine the length of any remaining drain band segment.
  • drain band segment has insufficient length, it will not be discovered until the final end of the segment is unwound from the roll while before the leading end reaches the predetermined depth. When this happens, the last insertion operation is unsuccessful. A rectification operation may become necessary, e.g. by either retrieving the drain band of insufficient length from the ground and replace the drain roll with a new one, or to insert a new drain segment at the same location. This last segment of drain band of insufficient length will have to be discarded resulting in material wastage and cost increase.
  • Embodiments of the present invention provide drain roll packages which are capable of supplying a continuous drain band for soil consolidation operation based on the prefabricated vertical drain technology.
  • drain roll packages structured according to embodiments of the present invention provide continuous drain band with a much longer length compared to the conventional drain roll packages.
  • a drain roll package includes a drain band and a reel around which the drain band is wound to form a plurality of windings.
  • the drain band has a core and a shield surrounding the core.
  • a cross section of the drain bans is defined by a width and a thickness. At least one of the windings is progressively shifted along a first axial direction of the reel such that a tail end of said at least one of the windings is offset from a head end of said at least one of the windings along the first axial direction.
  • the tail end is offset from the head end by a distance which is the same as the width, and a first subsequent winding of said at least one of the windings lies in a same layer around the reel as said at least one of the windings.
  • the tail end of said at least one of the windings is offset from the head end by a distance which is less than the width, and a first subsequent winding of said at least one of the windings partially overlaps over said at least one of the windings.
  • a drain roll package 100 for use in soil consolidation operation includes a continuous drain band 130 wound around a reel 110.
  • Drain band 130 has a core 137 and a textile filter fabric shield 139 surrounding core 137.
  • Core 137 and shield 139 may be made of plastic, e.g. polypropylene, such that the drain band can be resiliently deformed within a predetermined range without being damaged or broken.
  • Core 137 is of a corrugated form with hollow channels 138 which serve as water paths to allow water from the soil to pass through.
  • Shield 139 permits water to pass into core 137 from the surrounding soil, while restricting the soil particles from entering into core 137 which might clog channels 138.
  • Drain band 130 has a generally rectangular cross section ( Fig. 3 ), with a width 130W and a height/thickness 130H defining the profile.
  • Drain band 130 is wound around reel 110 to form a plurality of windings 131, 132, 133, etc.
  • windings for instance winding 131
  • winding 131 is wound around reel 110 starting at a head end 131a and ends at a tail end 131b to form a full round.
  • winding 131 is progressively shifted along a first axial direction 102 of reel 110. Wound in this manner, tail end 131b of winding 131 becomes offset from head end 131a along first axial direction 102.
  • tail end 131b of winding 131 is offset from head end 131a along first axial direction 102 by a distance 106 which is the same as width 130W of drain band 130.
  • Reel 110 has a length 110L longer than width 130W of drain band 130 to accommodate at least two windings to be wound without overlapping.
  • a drain band of a width of about 10cm and a length of about 3000 meters is wound on a reel of about 1.1 meter length. The drain band is wound around the reel in the above-illustrated manner, therefore it is possible to have 10 full windings wound around the reel at a same radial layer.
  • a further winding 141 is wound over the last winding of the first layer to start building the windings on the second layer, by progressively shifting the second layer of windings along a second axial direction 102' which is opposite to first axial direction 102.
  • Further layers are built by repeating the same process, i.e. with windings of odd-numbered layers progressively shifted along first axial direction 102 and windings of even-numbered layers progressively shifted along second axial direction 102'.
  • the winding operation is completed and a drain roll package is formed.
  • Such a package will have a larger axial dimension 110L, which can be the same as the size of several conventional drain roll packages stacked together.
  • the external diameter 110D can be controlled to be the same as that of a conventional drain roll package.
  • a drain roll package 200 has drain band 230 wound on reel 210.
  • Drain band 230 has the same structure as drain band 130 of the previous embodiment, i.e. formed of a core and a shield surrounding the core.
  • Each of first layer windings 231, 232, etc. is shifted along first axial direction 202 of reel 210, by a distance 206.
  • distance 206 is less than the width of drain band 230.
  • second winding 231 partially overlaps over first winding 231.
  • each subsequent winding in the first layer partially overlaps over a preceding winding.
  • a further winding 241 is wound over the last winding of the first layer to start building the windings on the second layer, by progressively shifting the second layer of windings along a second axial direction 202' which is opposite to first axial direction 202.
  • Further layers are built by repeating the same process, i.e. with windings of odd-numbered layers progressively shifted along first axial direction 202 and windings of even-numbered layers progressively shifted along second axial direction 202'.
  • the winding operation Upon reaching the predetermined external diameter 210D, the winding operation is completed and a drain roll package formed.
  • the present embodiment provides drain roll packages which contain and are capable of supplying a continuous drain band in a much longer length, comparing to a conventional drain roll, but without increasing the external diameter of the drain roll package. Drain roll replacement frequency during the soil consolidation operation, and the material wastage due to a last drain band segment of a possible insufficient length, are greatly reduced. Additionally, storage and transportation requirements limited by the external diameter of the drain roll package are complied with.
