Product Description

 

What is Wellpoint Dewatering?
A Wellpoint Dewatering system is a versatile, cost-effective pre-drainage solution that features individual wellpoints which are closely spaced around the excavation.

This technique utilizes vacuum to assist in lowering groundwater levels to create a stable, dry working environment.  Wellpoints are especially suited to shallower excavations or excavations taking place in fine-grained soils.
 

Wellpoint System Design

Wellpoint systems consist of a series of small-diameter wellpoints installed at a pre-determined depth (usually 23ft deep or less) on relatively close centers. They are quick to install & can handle a wide range of flows.

The pump serves three basic functions:

  • Creates vacuum & primes the system
  • Separates air/water
  • Pumps water to the discharge point

Wellpoint Installation

  • Pumps vacuum filter for wellpoint dewatering made from special shock resistant PVC pipes. The filter has a diameter of 50 mm and is equipped with 0.3 mm perforation at the bottom with a perforation length of one metre.

Single & Multi-Stage Systems

Wellpoint systems are limited by suction lift and can only lower water below grade to a certain point (depending on the altitude). Systems are often installed as a Single-Stage or Multi-Stage because of these limitations:

Single Stage

When excavations are 18ft deep or shallower, one row of wellpoints may be used to draw the groundwater below subgrade. Careful consideration should be given to the project altitude as higher altitudes will mean less available drawdown.

Multi-Stage

Wellpoints can be used on much deeper excavations, but multiple stages are required. If necessary, two or more rows of wellpoints are installed at different elevations. This is needed when the excavation is deeper than 18ft or when the altitude would prevent dewatering with a single wellpoint stage.

Company Profile

 

Qingdao Dewatering Pump Manufacturing Co., Ltd.one of the leading manufacturers of dewatering pumps, recommends two types of wellpoint pumps - rotary and piston.   With rotary wellpoint pumps, a vacuum is created by the rotation of a pair of rotors inside the pump housing.   As the rotors mesh a cavity is formed at the inlet of the pump drawing liquid into the housing.   As the rotors rotate, the liquid is carried in the pockets formed between the rotors and housing where the meshing of the rotors compresses the liquid and forces it out of the discharge port.
