Product Description: A soil‑sampling tool used for core extraction during sand‑filling tests to determine subgrade compaction. Main Technical Parameters: Large chisel: 45 cm long, 20 mm in diameter Small chisel: 40 cm long, 16 mm in diameter
Geotechnical wire saw, soil cutting and sampling,配套 tools, with handle for trimming soil samples
I. Product Overview Geotechnical wire saws are typically used for soil sampling and cutting. The wire tension is adjustable, and the tool comes with a rubber handle for convenient operation. II. Main Technical Parameters 1. Wire length: 300 mm 2. Bow depth: 140 mm
I. Product Overview This is a standard instrument used to prepare saturated soil samples from sandy soils and relatively permeable cohesive soils. It complies with GB/T 50123-2019 “Standard for Geotechnical Test Methods” and JTG E40-2007 “Highway Geotechnical Test Procedures.” II. Main Technical Parameters 1. Ring Cutter: Φ61.8 mm × 20 mm 2. Permeable Stone: Φ79.8 mm × 10 mm 3. Supplied with five ring cutters and six permeable stones, enabling simultaneous preparation of five sets of test specimens.
The core thickness gauge for textured geomembranes is used to measure the thickness of polyethylene geosynthetic materials in accordance with GB/T 17643. The core thickness of a textured geomembrane is determined by calculating the average of all measurements taken on identical test specimens. For each specimen, the thickness is measured at specified locations using a fixed geometric configuration and under defined pressure conditions, with the measurement taken perpendicular to the membrane surface and representing the distance between two measuring points on opposite sides of the membrane. This instrument complies with the requirements of GB/T 17643-2011 “Geosynthetics—Polyethylene Geomembranes” and CJ/T 234-2006 “High-Density Polyethylene Geomembranes for Landfills.”
DS-2 Model Digital Display Electric Butterfly-Type Liquid Limit Apparatus
The disk-type liquid limit apparatus is used to determine the liquid limit of soils for soil classification. It consists of a soil disk, a support frame, and a base. To use it, a sample prepared as a thick paste is placed in the disk, its surface is leveled, and a grooving tool is used to cut a groove in the soil. The disk is then lifted and allowed to fall repeatedly; when the soil groove closes to an appropriate degree, the moisture content of the sample is determined.
Electric hydraulic mold release device
This machine is a versatile device designed to demold specimens from the “Multi‑Functional Electric Compaction Apparatus,” the “Marshall Electric Compaction Apparatus,” as well as both light‑ and heavy‑duty manual compaction apparatuses, and to facilitate the removal of various compression test molds.
The Marshall electric compactor is suitable for preparing asphalt mixture specimens using the standard compaction method, enabling laboratory testing of the physical and mechanical properties of asphalt mixtures. It is also applicable to the fabrication of cylindrical specimens—Φ152 mm ± 0.2 mm × 115 mm or Φ101.6 mm ± 0.2 mm × 63.5 mm—for use in Marshall tests, indirect tensile tests, and other similar procedures.
TCDR-300 Dual-Plate Thermal Insulation Material Performance Testing Equipment
The TCDR-300 thermal conductivity meter is a new‑generation dual‑plate apparatus designed in accordance with GB 10294‑2008, “Determination of Steady‑State Thermal Resistance and Related Properties of Thermal Insulation Materials—Guarded Hot Plate Method.” It is used to measure the thermal conductivity of various homogeneous, plate‑shaped insulation materials as well as materials with poor thermal conductivity. Equipped with a microcomputer‑based automatic control system, the instrument boasts a high degree of intelligence, making it an ideal choice for conducting such testing today.
BZYS-4212 Surface Vibration Compactor
The BZYS-4212 surface vibration compactor is used to determine the dry density of non-cohesive, freely draining coarse-grained soils and gravelly soils (including rockfill). It is a testing instrument that employs the surface vibration compaction method to measure the dry density of such soils.
