Definitions

  • the invention relates to the use of a non-woven fabric made of synthetic fibers as a protective mat for covering objects to be detonated, these non-woven fabrics made from rhehrer webs connected by overlapping welded or sewn so large or laid by overlapping that the object to be blasted is covered by at least 1.5 m in both surface directions.
  • the object to be blasted has so far been used , especially in the most risky places for splinter scattering, with straw bales or other pressure-damping, inherently relatively rigid materials, such as old car tires, etc., covered at a certain distance from the endangered environment so that the detonation wave can spread over the distance and in Frontal direction is intercepted by the cover device.
  • Such covering or protective devices are, however, intensive in terms of transport costs and storage space and require a noticeable amount of work for their installation.
  • explosive sites can be covered simply and safely if they are loosely covered with a continuous filament fleece or staple fiber fleece made of thermoplastic fibers, which corresponds to certain requirements in the force-elongation behavior.
  • This loose cover which must extend beyond the blasting point to a certain extent, is lifted up somewhat by the detonation wave and captures the flying fragments without tearing.
  • it can even be used several times in succession with good success.
  • the invention accordingly relates to the use of a non-woven, textile fabric made of synthetic continuous threads or staple fibers or several such fabrics which are joined together by connection, such as welding or sewing, which are used to determine the tensile elongation behavior according to DIN 53857
  • a protective mat for covering objects to be detonated by overlapping the object to be detonated with this protective mat or with several of these protective mats is covered in such a way that the protective mat or protective mats protrude at least 1.5 m beyond the explosive field on each side.
  • the fleece used as a protective mat can be bound by needles or thermally.
  • the thermoplastic material from which the protective mat used according to the invention is made is, above all, polypropylene, crystalline copolymers of propylene and ethylene and polyester.
  • the explosive mat is to perform its function with high reliability and repeated use, a load in the medium expansion range of 10-80% is advisable, so that irregular pressure surges or scatter splinters caused by frequently unforeseeable inhomogeneities in the material structure of the explosive device can still be safely intercepted.
  • a larger mat area is required to securely cover the explosive object than the normal web width of the fleece used for the production of the protective mat allows, 2 or more fleece webs can be connected at the edges by overlapping welding or sewing, or else a 1, 5-2 m wide overlapping, loose laying is already sufficient to safely intercept the detonation pressure wave.
  • the detonating detonating cords, detonators, electrical bridge detonators and detonation retarders laid on the surface of the explosive field (below the mat) are covered with sand against the mat, or the mat should advantageously be laid at a short distance from the explosive ignitions.
  • Tensile elongation behavior according to DIN 53857 100 N / 5 cm at 10%, 400 N / 5 cm at 30%, 600 N / 5 cm at 50%, 700 N / 5 cm at 70% and 900 N / 5 cm at 90 % Strain.
  • Dielectric strength No breakdown with 30 kg fall bear from a height of 2 m.
  • This nonwoven was obtained by a conventional continuous filament nonwoven manufacturing process by spinning, air stretching and laying on a wire.
  • Size of the explosive device Length: 2.40 m. Width: 0.48 m. Height: between 0.90 and 1.40 m. Dimensions: approx. 1 m 3 per base. Reinforcement: 10 pieces of gate steel Q 14 mm as longitudinal and gate steel brackets as cross reinforcement.
  • Drill holes 5 pieces, 36 mm 0, 70-80 cm deep.
  • Ignition electrical with time stages 1-5 from south to north.
  • Objects to be protected In the west: Railway embankment. In the north: street and building. In the east: company building, fire wall. In the south: parking lot and building.
  • the mats were laid by 2 men so that they each protruded about 1.5 m above the blasting area and overlapped 1.5 m with each other. At the respective edges they were hammered inwards about 1 m below.
  • Scattering effect Insignificant due to the blasting. Individual small pieces of concrete were found about 5 m from the blasting field. Condition of the mats after being blown up: perfect.
  • Trim length 60-80 cm (full trim).
  • Ignition electrical. Instantaneous ignition.
  • Covering the blasting field 1 piece of a needled polypropylene continuous fiber mat 5 x 5 m, which means a covering of about 2 m beyond the blasting field.
  • Tensile strain behavior according to DIN 53857 70 N / 5 cm at 10%, 300 N / 5 cm at 30%, 550 N / 5 cm at 50%, 700 N / 5 cm at 70% and 800 N / 5 cm at 90 % Strain.
