tunnelbuilder.com - Häny company profile

Häny designs and manufactures grouting systems at its Meilen plant, on the shore of Lake Zurich in Switzerland.
The Häny equipment range includes mixers, agitators, grout pumps, compact grout plants, automated mixing and grouting plants, recording systems, packers and accessories.
Applications are in tunnelling, microtunnelling, pipejacking, directional drilling, dam construction, anchoring, diaphragm and slurry walls, soil mixing, and deep mixing.

Mixers Häny HCM high shear mixers offer excellent mixing performance, efficiency and wear resistance. They are available for cement, ultra-fine cement, bentonite and other admixtures, and can be equipped with a weighbatching system for mixing up to three dry components and three additives with water. Agitators Häny HRW agitators are used as holding tanks between the HCM batch mixers and the pump. The slowly revolving agitator homogenizes the grout suspensions, ensuring that air bubbles are removed.
Grout Pumps A full range of Häny ZMP grout and mortar pumps are available for almost every high and low pressure grouting and backfilling requirement. These low-wear plunger type pumps handle a wide variety of grout mixes, and are equipped with Automatic Pressure Control, which adjusts the pump output to the preset pressure and grout take of the ground.
Compact Grout Plants Häny Injecto-Compact grout plants comprise a HCM high shear mixer, HRW agitator, and ZMP grout pump, arranged functionally on a base with central lifting point. The components can be easily detached for individual use. Small grouting units are available for grouting tie-back anchors, rockbolts, soil nails, tension cables, and tube-á-manchette and rock grouting. Automated Mixing and Grouting Plants These are suitable for processing bentonite, fly ash, cement, rock dust, clay and similar suspensions for diaphragm and slurry walls, jet grouting, and large grouting projects. These are supplied as container or stationary plants.
Recording Systems A variety of Häny systems is available for measuring pressure and flow of grouts and to carry out Lugeon permeability tests. These range from simple HIR pressure recorders to fully electronic HFR units with data processing capabilities. Packers Inflatable packers, mechanical top hole packers, mechanical deep hole packers, and hand grout pumps are also supplied by Häny.
