In countries with hot climates, water collection tanks are used very widely.
For example, in the summer on the southern Greek island of Patmos there is no rain, and the vegetation, gardens and vegetable gardens, of course, dry out if not watered. Therefore, fresh water is very much appreciated here, and people have come up with a way to collect it.
In winter, during rains, water is collected from flat roofs in special containers for water (for more details, see the link • Крыша: плита перекрыти... ). The construction of such a tank is cheaper than the constant purchase of water for irrigation.
Capacities can be located under the house or near it. They can be built in many ways.
The first stage in the construction of such a capacity is to dig a foundation pit 02:15. The height of the pit should be slightly larger than the height of the finished tank, because we will make a drain under the tank.
Drainage under the 03:01 tank is necessary so that during heavy rains the water does not stagnate around the tank and goes deeper. The drainage system is done in layers (for more details see the link • Строим дом-4. ДРЕНАЖНА... ).
Pour rough concrete 03:28 onto the drainage system. It serves to make a smooth marking, it is easy to nail nails, put the bars and put the formwork. Reinforcing mesh can be placed inside the concrete for hardening.
According to the marking on rough concrete, we expose the outer formwork in a circle (this can be a stone wall or from boards).
On rough concrete we lay a special plastic fastener over the entire area of the future lower slab 04:13. And we put the reinforcing mesh on the mount.
We knit the reinforcement of the bottom plate, then the walls. Correctly connected reinforcement combines the bottom floor slab and the side walls of the future tank so that when casting they become one.
Fill the bottom concrete slab. Concrete is vibrated during pouring to remove all air and get the most uniform surface of the wall. 05:34.
We expose the inner formwork when the lower floor slab solidifies well.
At the stage of pouring concrete, air and water outlets must be made in the upper part of the tank. 11: 09,11: 23.
Fill concrete with the side walls of the tank to the level of the formwork. 05:46 Concrete is vibrating!
The formwork can be disassembled when the flooded walls have stood for 2-4 days.
We show three ways to build 06:17 tank walls:
With concrete walls - wooden formwork is placed on both sides and concrete is poured inside.
With concrete walls lined with stone. First, concrete is poured, then the outside of the wall is thrown with 07:34 mortar and lined with natural stone. For more information about the upload, see the link • Техника штукатурного о... .
With monolithic walls - on one side is a stone wall, on the other concrete. First, we lay out a stone wall, which in this case is an external formwork. Then we put the inner formwork, wooden, and pour concrete. Concrete penetrates into all cracks, filling them and clinging to the stone, like a suction cup. Thus, a monolithic wall is created.
In each of the methods inside the walls there is a reinforcing mesh.
In this project, water tanks are located under the house and are part of the foundation of the house on two floors. Therefore, to increase the bearing capacity, we reinforced the concrete walls of the tanks with stone - according to method 2 and 3. In my opinion, method 3, monolithic, is more correct when building stone-concrete walls.
Rough masonry 08:23
The rough masonry (or lining) of the container is made of hard stone. The principle of masonry is the stones “in depth”, so that over time they are not squeezed out, and they do not fall out of the masonry. The main goal of this masonry is to have a good “skeleton".
When the rough masonry is ready, grout it 10:23.
Around the tank made a drainage pillow 10:53. Drainage should be done to the height of the water tank.
If groundwater is close to the surface of the earth, like ours, then a drainage pillow is a must.
Now it remains to make the top slab 12:07. On the upper horizontal formwork of the container we put a plastic film, then we make a small wooden formwork for the access door to the water, in our case there are 2 of them. Throughout the entire area of the upper floor slab (except for hatches) we knit reinforcement, bandaging it with the reinforcement wall. And pour concrete. The top floor slab should stand for 20-30 days until completely dry.
The well is another feature of the project. 12:58.
