    Product description

    An inclined entrance allows a medium-length bunker to be buried into a slope or flat ground. Partially buried, the bunker is exceptionally easy to install. Fast and affordable installation is guaranteed. The earth that was dug up forms a cover over the bunker, adding thermal insulation and concealing it underground. 

    The bunker is made even more practical to use by a straightforward, pleasant stairway made of sturdy aluminum with an aluminum step profile, as well as by a tall enough entrance. 

    The plastic construction and the poured cement are securely linked by lateral supports and steel rebars. Kolomaki Quick’s vaulted ceiling design makes it more resilient than typical rectangle constructions. 

    Welding equipment of the most recent generation and premium polypropylene assures the durability of our bunkers Quick. Our bunkers don’t need any special maintenance or metal degradation prevention measures. 

    A family of 4 can use this bunker comfortably for a prolonged period of time as it will fit 4 beds and additional furniture. Additionally, a family of up to 8 individuals can wait out a catastrophe in safety and comfort by using Bunker Quick 1 3000. It can accommodate up to 8 pieces of furniture, such as five chairs or three small beds. For more space, we advise using folding beds and chairs.

    This bunker is available in smaller sizes. For smaller variants see:

    Installation

    Installation of a bunker for concreting Kolomaki Quick:

    The bunker for concreting is also suitable for places with a higher static load.

    Installation procedure:

    At the selected location, we make a 20 cm wider excavation on each side of the bunker (see drawing) to create a working space for concreting.

    The bunker is placed on a compacted and levelled 100 mm thick layer of aggregate fraction 8/16.

    We will install the bunker using mechanisation. After settling the bunker, we will make a concrete slab with a height of 100 mm on the floor. Due to the load during concreting, after the bunker floor has hardened, it is necessary to support the ceiling using 4 stands and one wooden beam in the center of the ceiling.

    The walls of the bunker must be reinforced with 2 longitudinal wooden prisms 80/80 mm placed at a height of 500 and 1000 mm before concreting. These prisms will be spanned using horizontal wooden spacers of 80/80 mm placed approximately at quarter lengths of the beams. Only then is it possible to concrete the cellar walls.

    If the bunker is installed in places with a high groundwater level, drainage must be provided around the bunker with water drainage outside the bunker. The bunker is not intended for places with groundwater.

    We must not pour more than 100 cm of concrete in one day. The thickness of the concrete around the bunker is recommended to be 150 mm.

    Stand-off and removal of struts can only be done after the concrete has hardened sufficiently – at least 10 days.

    Construction excavation:

    The construction trench must be excavated in a sufficiently large area to maintain the width of the working area. The slope, or the slope of the excavation, will result from the local geological conditions. The recommended slopes of the construction pit walls are: 

    Ground type Ratio of height to length of the slope
    Dusty clay 1 : 0,25
    Clay gravel 1 : 0,25
    Earth 1 : 0,25 – 1 : 0,5
    Clay 1 : 0,25 – 1 : 0,5
    Clay loam 1 : 0,25 – 1 : 0,5
    Sandy clay 1 : 0,5
    Boulder sand 1 : 0,75
    Loamy sand 1 : 1
    Sandy earth 1 : 1
    Sandy gravel 1 : 1
    Rocky earth 1 : 0,5 – 1 : 0,2

    In the case of more complex geological conditions, the structural engineer will determine the protection of the walls of the excavation.

    The dimensions of the construction excavation are determined by the type of bunker – see drawing. The maximum height of the embankment in standard installation is 40 cm above the basement.

    Location relative to buildings:

    The bunker must not be bellow a building. Loads caused by any construction could lead to deformation of the structure. The bunker must be at least 1 meter away from the building.

    Location on a slope:

    If the bunker is located on a slope, it is important to check the terrain to prevent landslides or other complications. A static calculation and assessment of the suitability of the stability of the subsoil or slope is carried out by a structural engineer or building designer every time the bunker is placed on a slope.

    Non-standard mounting situation:

    All non-standard assembly situations must be assessed by the structural engineer or building designer in order to exclude possible damage or imminent danger. On the basis of the project, a static assessment prepared by a professionally qualified authorised person must also be provided.

    Transportation:

    The bunker must be transported, loaded and unloaded with care. Impacts during loading and unloading are not allowed. Fastening the cellar during transportation must be done carefully, it is not allowed to use excessive force that can lead to deformation of the product body. It is recommended to load and unload the bunker using a crane, excavator or a forklift.
