  • the present invention discloses a man-portable, relocatable fighting bunker assembly.
  • the assembly is comprised of, but not limited to, a plurality of metal segments having variation in shape to provide adequate protection by deflecting the bullet with Z shape profile section and three or more loop holes for effectively engaging an enemy; the interlocks of a metal segment join together the individual segments to form a complete wall; interlocks can be sealed with a preformed polyurethane interlock seal to achieve a watertight joint- if necessary; and wherein further camouflage of the fighting bunker by placing earth, stones and local material all around it is carried out to avoid direct observation from a distance by the enemy.
  • the metal segments are driven, hammered, drilled, sliced in normal applications for placing and grooving of adjacent sections, which is sufficient to form an enclosure thereby in desert regions.

  • the Panel segments at which, location, loopholes are to be provided are to be cut to the required shape.
  • the segments at which location the loopholes shall be cut further identified and be provided with frame covering both the rows / layers of walls along with the gap to retain the sand.
  • the panel segments are cut to shape, as per design, and are transported to the desired location man-portable from road head.
  • a manportable, relocatable fighting bunker assembling method comprising the steps of, but not limited to: providing, the size of the fighting bunker is marked on the ground, as per practice; providing, the position of the door is marked for the segments to be clear of the location; providing, the segments of alternate heights are placed side by side; wherein the segments are slided on the grooves in the segment; providing, the alternate height segments are assembled over the first row, similarly, by sliding in the grooves of the segment; providing, after the position of the loop hole has been reached, care should be taken to slide the segment which has been cut for the loop hole; providing, the additional trapping for the loophole should be fixed to support the segment above and also to retain sand, if two layers of metal segments are used; providing, the last row of segments is again placed similarly by sliding the segments on the groove, to achieve better bonding between them for structural rigidity; providing, after the top row of segments have been placed, supports for the ISMB- to be placed above
  • Steel is a homogeneous building material whose load-deformation behaviour is characterised by an elastic portion and considerable plastic reserves.
  • the low carbon steel is used in any retaining wall type that is installed into the ground by driving or pushing, rather than pouring or injection.
  • the metal segments of low carbon steel have a large bearing capacity. The metal segments can penetrate through stiff layers or boulders. The volume of soil displaced during the driving of steel piles is less, and can withstand rough handling.
  • carbon is the most important alloying element in steel and can exist either dissolved in the iron or in a combined form. Increased amounts of carbon increase hardness and tensile strength as well as response to heat treatment but Low Carbon steel is best suited to withstand bullet penetration.
  • the strength, speed and flexibility of assembling segments of metal sheets makes it ideal for all forms of temporary and permanent works.
  • the durability and ease of extraction means that light sheet piling driving can be re-used in sustainable construction. Sheets produced, conforming to Indian Standards, in lengths from 1 -12m and upto 8mm thick, 0.69m wide and max 69.40 Kg/metre to 100.58 Kg/metre2 length can suit requirement for a Permanent Defense.
  • Z-Profiles are more suitable to be adopted for Permanent Defenses (PDs) (fighting bunkers).
  • PDs Permanent Defenses
  • Z-Profiles with their optimum distribution of material, are the most efficient sheet piling sections available for bending strength.
  • the Z-Profile is the optimal section for weight and strength, coupled with driveability, wherever required (as in deserts or loose soils).
  • the variation in shape too provides adequate protection in deflecting the bullet during close quarter battle.
  • the Z shape allows for three or more loop holes for effectively engaging the enemy unlike the only two small loopholes in the present design.
  • the interlocks of the metal segment join together the individual parts to form a complete wall. Interlocks can be sealed with a preformed polyurethane interlock seal to achieve a watertight joint- if necessary.
  • the Z- type sheets is predominantly used in retaining and floodwall applications where bending strength governs the design and no deflection (swing) between sheets is required. Turns in the wall alignment can be made with standard bent or fabricated corners. Typical configurations are shown above.
  • the service life of low carbon steel structure is to a large extent dependent on the natural process of corrosion.
  • a corrosion rate of as low as approx. 0.01 mm/ annum makes its life equivalent to a hundred (100) years.
  • the defensive operations defeat an enemy attack, buy time, economize forces, or develop conditions favourable for offensive operations.
  • Their purpose is to create conditions for a counteroffensive that allows Army forces to regain the initiative.
  • the inherent strengths of the defence include the defender's ability to attack and use the available time to prepare his defences.
  • the static and mobile elements of his defence combine to deprive the enemy of the initiative. He contains the enemy while seeking every opportunity to transition to the offense. Considerable time is saved for the soldier in preparing his defences by use of the Steel Sheet segments and for the ensuing battle to channelize the enemy.
  • the metal segments are driven, hammered, drilled, sliced etc in normal applications.
  • the placing and grooving of adjacent sections are sufficient to form an enclosure thereby further easing the construction process and is an advantage over all other types of construction.
  • the metal segments can be hammered or driven into the ground in the desired shape and depth after which excavation of the earth can be carried out. This saves valuable time in preparing defences.
  • the advantage of using the Steel metal segments is that overhead protection in the form of Steel Roof Trough can be placed with earth cover as per design, immediately after erection of the enclosure.
  • a PU Foam can be pasted on the inner side of the PD as an insulating material which is otherwise not possible in the conventional PD.
  • the metal sheets are proposed to be in sizes of 35 cm and 42 cm heights for man-portability (one or two men) and easy carriage to the place of erection.
  • the weight of the Z shaped metal sheet pile being 69kg per metre, it is cut into segments that are man-portable easily.
  • the sizes decided for easy assembling and structural soundness are - 35 cm height segment and 42 cm segment height.
  • the panel segments are cut to shape, as per design, and are transported to the desired location- man-portable from road head.
  • supports for the ISMB- to be placed above- are suitable fixed at the designated locations.
  • ISMBs are fixed on to the supports and suitably anchored.
  • Suitable earth is placed over the SRTs as per procedure, for a height not less than 60 cm.

Abstract

La présente invention divulgue un ensemble bunker de combat repositionnable portable, et un procédé associé. L'ensemble comprend, mais sans y être limité, une pluralité de tôles d'acier à faible teneur en carbone présentant des formes définies à variation de forme pour fournir une protection adéquate par déviation du projectile grâce à une section de profil en forme de Z pour au moins trois meurtrières afin d'affronter efficacement un ennemi. En outre, les dispositifs de verrouillages des tôles d'acier à faible teneur en carbone relient ensemble les divers segments de palplanches pour former une paroi complète ; les dispositifs de verrouillage sont scellés au moyen d'un joint d'étanchéité de dispositif de verrouillage en polyuréthane préformé pour obtenir un joint étanche à l'eau, si nécessaire. En outre, le camouflage du bunker de combat, à l'aide de terre, de pierres et de matériaux locaux disposés tout autour de celui-ci, est réalisé pour éviter une observation directe par l'ennemi depuis une certaine distance.
