Model IGE-81 - Wellpoint Systems

0

The IgE-81 wellpoint systems are designed to drain building trenches and excavations in low and medium permeability soils (permeability coefficient k <40m/day). The system may be used as an independent installation or a support system for other drainage inlet types in one- or two-level arrangements. One wellpoint level makes it possible to lower the ground water table up to 4 m, and two levels, up to 7 m. All metal elements of the system are made of aluminium.

Wellpoint system options: IgE 81/32 and IgE 81/63

Wellpoint systems are available in two versions: IgE 81/32 and IgE 81/63. Both versions differ from each other above all in the wellpoints that are used. The most commonly used version, IGE 81/32, is based on flexible wellpoints, 32 mm in diameter.

In the case of the IGE 81/63 option, diameter 63 wellpoints are used. This version allows for more efficient drainage. As compared to version IGE 81/32, a flexible connector with gaskets is additionally required for each wellpoint in order to connect it to the suction header pipe. Also, the suction header and the stoppers that close its ferrules are different.

Standard package of wellpoint system

Elements of wellpoint systems can be order in packages or separate elements. Elements of wellpoint systems like flexible wellpoints and suction header pipes can be regenerate.

Typical packages is for 50 or 100 wellpoints typically used for 50 or 100 m length of dewatering.

Wellpoints systems diameters - 89, 108, 133 mm Typical diameter for IGE 81/32 wellpoint system is 133 mm. IGE wellpoint systems also can be made with pipes of 89 and 108 mm diameters.

The IgE system variant with polyethylene elements

Another available variant of the IgE wellpoint system is one in which certain elements (suction header pipes and bends) are made of modified HDPE polyethylene.
The range of operation for a system like that is the same as in the case of fully aluminium systems. It is recommended that polyethylene elements be stored either under a roof or cover.

  • Order - How to order

As compared to conventional structures, the IgE-81 wellpoint system has the following properties:

  • reduced amount of work when installing and uninstalling the system (connections between wellpoint and suction header pipe and between individual header pipes are simple, quick and leaktight),
  • easier transport and reduced labour demand involved in transport (light materials for wellpoints and suction headers and reduced amount of components),
  • high wellpoint durability, which allows for their repeated use (wellpoint material is resistant to corrosion and low temperatures, and the simple design of the typical filter facilitates its cleaning),
  • two casing pipe types in two lengths, added to the set, which make it easier to install wellpoints in different soil conditions and at any depth.

Wellpoint systems are broadly used and recognized in the construction of drainage systems for building trenches/excavations. Wellpoint systems are designed for draining fine-grained soils, which do not give water easily. Their characteristic feature is a system of densely spaced inlets with small cross-sections, connected in paralell via a suction header pipe with a pumping engine.

Main applications of wellpoint systems

Example applications:
  • Dewatering water from a ground when excavations below ground water level are needed
  • Dewatering construction excavations
  • Lowering of ground water level
Other applications of wellpoint system:
  • Dewatering in agriculture
  • To gain water for house, garden and irrigations
Jetting wellpoints into the ground
    The typical sequence of operations when installing wellpoints is as follows:
  • connect jetting pipe to water jetting pump or hydrant, using jetting hose
  • if you are setting the wellpoint manually, position the jetting pipe vertically with its edge on a support (e.g. piece of thick board), next to the predetermined wellpoint setting location
  • when you set the wellpoint with jetting pipe using a crane, keep the pipe on the crane rope 150-200 mm above the wellpoint setting location
  • activate water jetting pump or open the hydrant
  • when water flows out of the jetting pipe, remove it from the support and lower it to the ground
