FIELD: blasting. ^ SUBSTANCE: antiblast chamber comprises a cylindrical metal casing, two bottoms of convex shape, a multilayer metal fragment protection and a beam with a carriage. The metal casing is made of two coaxially arranged pipes separated with a gap and sealed at the ends. The protection is installed on the inner surface of the casing and bottoms and is made at the side of bottoms in the form of meshy dampers. The beam with the carriage is installed inside the chamber longitudinally in the upper part. In the chamber there are holes for elements of operational purpose covered with armoured turrets from inside. The chamber is equipped with circular flanges connecting the casing with bottoms. Inner diameters of the casing, flanges and bottoms are equal in value, the holes for elements of operational purpose are made in every of the casing flanges. The holes are arranged along the vertical axis of the flange, equipped with locking devices. The beam with the carriage is installed in an insert. The fragment protection at the side of the casing is made in the form of a hollow cylindrical insert installed in it coaxially and with a gap having flanges resting against the inner surface of the casing flanges. Each layer of the insert is separated with a filler. ^ EFFECT: invention provides for reliable confinement of blasting products, meeting the requirements of ecological safety. ^ 2 dwg |
