How to make a cisson for a well

The borehole caisson is a hermetic structure in the ground over a well, a depth of 2 m. The caisson is made of plastic, bricks, concrete rings, metal and concrete. Caissons are cylindrical, rectangular and square shape.

Inside the besson for the well is:

Pressure gauge and other automation.
Filters.
Pump.
Expansion tank.

Why do you need caisson for well?

Cement is done to protect the well and water injection equipment:

From freezing of water in pumping equipment in winter.
From getting groundwater.
From outsiders.
From entering the well, and hence both in water, frogs, mice and various insects.

How to make a cisson for a well - start of work

To begin with, you need to decide what material will be constructed from the caisson.

Then the following:

To dig around the well, a depth of approximately 2 m, and the diameter should be 20-30 cm larger than the diameter of the caisson itself.
The pit is digging such a magnitude so that all equipment for the well placed, only the hatch should be outside.

How to make a cable for a well made of concrete rings

To make a cesson for a well made of concrete rings, do the following:

The bottom of the cylindrical pit is poured by concrete solution.
We give concrete to completely seize and dry, and then the bottom we clean and mine from the soil fallen from above.
We measure the height of the concrete ring and smear the concrete solution the same height in the hole, and then set the ring.
After the 1st rings, we set the same method 2nd, and the following.
If the soil fell under the establishment of the rings on top, we remove it and throw it up.
After installing the concrete rings, we smear all the seams with concrete solution.
On the upper concrete ring of bricks, we make a construction, a kind of well, so that the height of the hatch was 15 cm above the ground level. It is necessary in order not to register inside the melt water.
We close the well insulated hatch.

How to make caisson for well concrete

Concrete caisson do this:

Dig a hole.
Install the formwork in the pit.
Then set the grid in a hole from the reinforcement.
We proceed the bottom and wall with concrete solution, leaving the holes for lining the pipes and the electrical cable.
We extend the gloves from the brick from the brick, close the insulated hatch.

How to make a cisson for a bore of a brick

Such a caisson is not suitable if in your area is near groundwater. He can pass the water inside.

Kesson from bricks can be made in two ways:

Brick fits tightly to the wall.
Poam walls in size more than Kesson, and the space between the caisson and the pit is covered with soil.

Top Cesson is narrowed, speaking over the surface of the earth, and is covered with insulated hatch.

Plastic Coxon for Well

Plastic caissons are the most common now. Such caissons made of plastic, 2 cm thick, and different colors.

The plastic caisson is not necessary to build, it is bought ready and installed in the pit.

Advantages of plastic caisson:

A small weight - it can be installed by itself, without a special crane.
Low price.
Durability.
Does not need insulation.
Sealing - groundwater, if it is close to the surface, will not fall inside.

The lack of plastic caisson is only one - it is not sufficiently hard, which can lead to its deformation under the influence of external factors.

But this problem is solved quite simply: on the perimeter of the pits cover it with cement mortar, let dry, and then lower the plastic caisson.

Metal Kesson for Well

Metal caisson do it yourself:

Metal caisson is made of a metal sheet, a thickness of 0.5 cm using a welding machine and a hacksaw for metal.
First weld the cylinder. It leaves the holes for the cable and the plumbing pipe.
Then welded the bottom to the cylinder, cutting the hole and equipping it with a special sleeve to make it easier to install the caisson on the casing on the well.
From above, the cylinder is equipped with a narrow neck with a lid.
Ready caisson paint oil paint on top and inside to protect the metal from corrosion.

Installation of metallic caisson:

Before installing the caisson, the casing is cut into the ground with the ground.
Lowering the caisson on the bars, dress the sleeve on the casing, and then hermetically welded it to the bottom.
Metal caisson is installed so in the pit so that only the hatch is performed on the surface, 10-15 cm, everyone is buried in the ground.
Metal caisson and cover inside need to be insulated.
