Concrete water tank

Each dachnik knows that it is necessary for watering a warm, heated water in the sun. For this, daccias use all sorts of capacity: barrels, etc. I'm on my land plot i use concrete tanks. Make them die every gift.
To do this, first of all you need to prepare a mobile formwork.
The dimensions of the formwork are calculated individually, depending on the volume of the future tank. My formwork (see the drawing) is calculated on 600 liters with a height of 1 m. You manufacture all parts of the formwork, it needs to be assembled and to dig the pit under the foundation. Increase the length and width of the pit at 5 cm! At the bottom of the pits, pour sand (5 cm). The thickness of the foundation is 30 cm.
When the foundation concrete will cause (in the summer of 7 days), you can start collecting the formwork and cast the walls. The bottom of the container is cast simultaneously with the walls! To do this, you need to cut down the boards with a width of 10 cm from below, turn them off after the formwork is removed. The thickness of the walls of the tank should eventually turn out to be 10 cm.
For accuracy between shields temporarily settling on the pouring pieces of rails 20x20x100 and tighten the hairpins. During the fill of the concrete, it is necessary to lay fittings. You can add a mesh or bend the wire rings with a diameter of 6-8 mm. The distance between the reinforcement is 15 cm. Concrete needs to do very strong, cement does not save. Concrete composition:
• 1.5 sand buckets,
• 1 bucket of cement 400 grade,
• Crushed stone (1 bucket with a diameter of 10-20 mm).
Mix thoroughly. Concrete should be liquid to easily pour into formwork. During the pouring, the formwork needs to be tagged with a hammer, then concrete will take place without shells. After 10-12 hours, when concrete clutches, it is necessary to remove ^ tie studs, because In the morning it will be very difficult to remove them. In the morning we remove the inner shields, and in a day - external. After that, we collect a formwork again on the cast wall and fill again.
When pouring the first row and the bottom, do not forget to insert a piece of pipe with a carvings, then to wind the valve later on the thread, as the water for the winter needs to be merged.
When the container will be cast, it is necessary to be inside sick-up. To do this, we prepare a solution: 1 sand bucket, 1 cement bucket No. 400. It is desirable to add liquid glass to the solution (1 cup) or waterproofing (500 g per 10 kg of cement). On the second day after plaster, the container can already be filled with water.
For the winter, it is necessary to drain water, and cover the container with a lid, rubberoid or roofing glands, fixing so as to the wind. The upper part of the tank should have a bias so that water flows from the lid. With proper operation, the container will last for a very long time.
On a note:

People who are loving comfort and convenience will definitely build a swimming pool at the cottage. It's nice in sunny weather to sow in the water or swim. But the pool service Very time-consuming work, so it is better to entrust her professionals that will qualitatively spend all cleaning work in the pool, correct the breakdowns. And you will enjoy the fresh air of nature and clean water of your pool.
