Definitions

  • This invention relates to a ground water drainage system particularly a drainage network for construction sites.
  • the drainage network of this invention includes multiple drainage strips that have channels covered by filter means which can divert water from the ground rapidly and efficiently. By draining rain water and accumulated underground water the hydraulic pressure exerted on the ground is released effectively. This invention thus increases ground stability and prevents earth movement from occurring at a construction site.
  • a drainage network 5 comprising a plurality of drainage strips 50 in a network configuration.
  • Each drainage strip 50 possesses a channeled strip 511, two pairs of high tensile strength polyester fibre bundles 512 and 513, and a drainage belt 514.
  • a channel containing strip 501 including two sets of high tensile strength polyester fibre bundles 512 and 513 is embedded in the channel strip 511.
  • the strip 501 is formed by moulding using a moulding apparatus in which two sets of high tensile-strength polyester fibre bundles 512 and 513 separated by an appropriate distance are embedded in a polyethylene material.
  • the centre of said strip 501 is equipped with the channel 502.
  • a drainage belt 514 is inserted into said channel 502 by a machine, thereby forming said drainage strip 50.
  • a polyethylene material is used to form the strip 511.
  • the two sets of high tensile-strength polyester fibre bundles 512 and 513 are embedded in the strip 511 and are spaced to form the two slot-defining strips 501.
  • the drainage belt 514 inside slot 502 at the centre of said slot-containing strip 501 provides means for rain water and underground water to be drained from a site equipped with said drainage network.
  • the principal object of this invention is to provide a drainage network having hollow channels by which an effective drainage network system can be established in ground structures.
  • Another object of this invention is to provide a drainage network provided with filters to increase ground stability and prevent earth movements.
  • a ground water drainage network comprising a number of interlocked strips for embedding in the ground and forming a water permeable network or mesh structure characterised in that each drainage strip comprises one or more high tensile-strength fibre bundles embedded in a polymeric material by a moulding process thereby forming said strip, the said strip having at least one recessed or channeled portion said portion being covered by a water permeable sheet inserted therein.
  • the drainage network has filtered channels which comprise a plurality of drainage strips and connection strips connected with each other.
  • the drainage strip has a channel strip, sets of high tensile strength polyester fibre bundles, and a drainage filter.
  • the high tensile strength polyester fibre bundles are embedded in the channel strip.
  • the centre of said strip is equipped with a plurality of channels and a drainage filter is connected and covered on the top of said strip.
  • the hollow channels at the centre of said strip provide the most efficient means for accumulated rain water and underground water to be drained from a construction site equipped with said drainage. Therefore ground stability is increased and earth movements prevented on the site.
  • the drainage network 1 has filtered channels and comprises a plurality of drainage strips 10 interconnected by cross-strips 20 and being interlocked with each other.
  • said drainage strip 10 has a channeled strip 11, multiple sets of high tensile strength polyester fibre bundles 12 and a drainage filter sheet layer 13.
  • the said sheet 13 may be bonded to the top surface of the strip 11 by adhesive or mechanical means.
  • the strip 11 is formed by moulding using a moulding apparatus in which the high tensile-strength polyester fibre bundles 12 separated by an appropriate distance are embedded in a polyethylene material.
  • the centre region of said strip 11 has a plurality of smooth channels 111.
  • the drainage filter 13 forms a cover and is attached on the top of said strip 11 allowing water to pass through and flow into the channels 111.
  • the unimpeded channels 111 provide a fast, large and most effective drain for underground water.
  • the networks 1 can be laid in tiers upon each other in the ground during installation to increase ground stability and prevent earth movement.
  • a polyethylene material is used to form the strip 11.
  • the high tensile-strength polyester fibre bundles 12 inside said channels 11 have many properties, such as durability, UV resistance, chemical resistance bio-resistance and tensile strength.
  • the fibre material forming the bundles 12 possesses a tensile strength comparable to that of soft steel when elongated less than approximately 20%.
  • the unimpeded channels 111 of this invention can provide a fast, high capacity and most effective drain for underground water.
