,Froc Eastern area dry next week-Hesco barrier

Originally designed for use on beaches and marshes for erosion and flood control, the Hesco Bastion quickly became a popular security device in the 1990s.

1) Are the structures of buildings such as shophouses, commercial buildings and housing estates strong enough to tolerate water pressure?

This basically depends on the construction standard. Normally, concrete buildings are stronger than those made of wood since there are steel bars inside the concrete. If the building is designed and constructed according to professional standards, with sufficient steel bars and proper pillar size,树池钢格板, it is quite certain that the structure can withstand the pressure of no more than two metres of water without grave structural damage or falling down.

2) Which part of the building can be damaged most in massive flooding?

Brick walls and the floors are the most vulnerable during a flood because they are the parts that come into direct contact with the water. The larger the surface, the more area will be affected by the floodwater and the pressure that comes with it. So, damage is more likely to occur to these parts compared to beams and pillars.

At one metre high,Playground Fence, the water will exert pressure of 1,000 kilogrammes or a tonne per cubic metre. This will be doubled if it is two metres high. In reality, the wall and surface are only designed to put up with pressure of 100-200 kilogrammes per cubic metre for the walls and 200-300 kilogrammes per cubic metre for the floor. Therefore, huge pressure from water up to two metres deep may cause the wall to collapse and the floor to become warped and cracked. Wooden structures may become loosened.

3) What are the chances of the beams and pillars cracking?

Beams and pillars may be damaged if they are too small. Knock-down materials that are widely used in new housing estates can be a problem as there may be cracks in the connecting parts.

Besides, long-standing floodwater may devour parts of small pillars, exposing the steel bars to the water and causing them to rust. If this is the case, they urgently need to be fixed or the structure may crumble. If the cracks are severe, the beams will need to be replaced

Remain calm if you spot damages and cracks on beams and pillars as these may only be on the surface. If you find any cracks, call an engineer to check them

4) What about the foundation?

There are two types of foundation, one with foundation piles underground and the other on the ground. Watch out for the underground structure to make sure that the foundation pillars remain intact. At the same time, the water may wash away the soil that holds the on-the ground foundation, causing the structure to become unbalanced.

5) Buildings with basements need special care.

Pumping water from a flooded basement must be carried out step-by-step with extreme care. Doing it in a rush can cause further damage. Initially, it’s necessary to keep pressure balanced between the water in and outside the basement, or pressure outside the basement will push the wall, causing serious cracks in the structure. It’s better to wait until the water outside recedes before siphoning the water from the basement.

6) Some guidelines for structural repairs.

If not severely damage, construction adhesives can be used for cracks in the walls and beams. The rust on steel bars needs to be removed and covered with rust-proof paint. Reinforcing the steel bars may be necessary.

Broken pillars must be removed and replaced immediately to prevent the structure from falling down.

Warped floors and walls must be fixed or rebuilt.

If the main structure slips from the foundation, it’s necessary to have a new foundation built. Call an engineer

7) Other concerns in addition to structural repairs.

Further checks are needed for damage to other parts of the house, like parquet floors, doors and windows as well as paint and wallpaper. Some works, like the electrical system, require a professional.

If there are any doubts about inspecting buildings, call the Engineering Institute of Thailand on 02-319-24103. From www.thaireform.in.th/news-health-system/item/ 6671-2011-11-14-10-03-35.html.

The QIAOSHI’s Military Barriers or Hesco Bastions is a modern gabion used for flood control and military fortification. It is made of a collapsible wire mesh container and heavy duty fabric liner, and used as a temporary to semi-permanent dike or barrier against blast or small-arms. One of the less heralded life- and labor-saving devices of war, it is used on nearly every United States Military base in Iraq as well as on NATO bases in Afghanistan.
