bultning

Bultning is a Swedish noun derived from the verb bulta, meaning to bolt, strike, or beat. The term has several senses depending on context. In technical and industrial usage it most often refers to the process of securing rock, soil, or structures with bolts, a standard method in geotechnical engineering and mining. In everyday language, bultning can also denote a pulsating sensation, such as a pounding heart or throbbing pain.

In civil and mining engineering, bultning involves installing anchors or bolts into rock or masonry to improve stability. Work typically includes drilling holes, inserting bolts or expandable anchors, applying resin or grout, and tensioning the bolts to absorb stresses. The technique can be used for tunnel supports, slope stabilization, or temporary supports during excavation, often combined with shotcrete, mesh, or other reinforcement systems. Safety considerations include correct hole spacing, bolt length, and load testing.

In medical or colloquial use, bultning describes a throbbing or pounding sensation, such as a strong heartbeat, pulse in a limb, or headaches. The word is often found in phrases that describe sensations, such as a pounding in the chest or head.

Related terms include bolting, rock bolt, and throbbing. The concept is widely used in Swedish technical vocabulary and may be encountered in engineering manuals, construction projects, and medical descriptions.
