The subject of the contract is the delivery of an automatic filtration coefficient testing apparatus (one set) for PGI-NRI.
The detailed scope and method of execution of the object of the order is specified in:
- Annex 1 to SWZ – Description of the subject of the contract;
- Annex 2 to SWZ — Designed provisions of the contract.
Delivery of an automatic filtration factor testing apparatus (one set) to the CBGS PIG-PIB laboratory
The set at issue in the proceedings consists of:
• Permeability test chambers for samples with a diameter of 70 mm. The test chamber shall have at least 5 ports for hydraulic connection and a breather valve, maximum pressure applied to the chamber up to 2 MPa. The chamber is to be equipped with a lower base and an upper dome with two drainage pipes with a diameter of 70 mm.
• A pressurization system in a configuration that allows pressure to be applied to the permeability test chamber and independently of the ceiling and floor of the test sample.
Requirements - the system mentioned above is to be characterized by the following parameters: volume at least 200 cm3, volume measurement resolution 0.001 cm3 and maximum pressure at least 1700 kPa, pressure resolution 0.1 kPa. Other specifications: automatic control against exceeding pressure and volume, volume accuracy up to 0.25% and pressure up to 0.15% of the total measuring range.
• Pore pressure sensor up to 2 MPa.
• Data control and acquisition system - a set of devices and software that allows you to control the phases of the permeability test, registration and acquisition of data obtained during the test and a program / template that allows you to analyze the obtained measurements in a spreadsheet. The proposed solution must allow for the full conduct of the test, analysis of the obtained data along with the calculation of the filtration coefficient.
• A set of accessories for sample preparation for coarse and fine soil permeability testing, consisting of a two-part mold for 70 mm samples, a 70 mm manual sampling sampler, an O-ring placement tool for 70 mm samples and a 70 mm membrane placement tool.
• A set of additional accessories necessary to perform permeability tests (pore stones with a diameter of 70 mm and a height of 6 mm. 2 pcs, latex membranes with a diameter of 70 mm and a length of at least 235 mm - 10 pieces. O-ring gaskets 70 mm at least 10 pieces, tool for placing the membrane on samples with a diameter of 70 mm, tool for placing the O-ring on samples with a diameter of 70 mm)
• Nylon cable with a diameter of 6mm x 8mm and a length of at least 10 m.
Other requirements
