Gutters are a structure for draining or mechanically transporting liquid to the desired location. Such a device is a useful, effective assistant both in everyday life and in industrial conditions, in the road system, and the construction industry. It is the construction type of gutters that will be discussed. A construction gutter for concrete is a simple design that you can actually make with your own hands. With such a gutter it is possible to ensure high-quality, uniform placement of concrete mortar during the construction of the foundation for a building.
Types of gutters
There are several types of gutters for pouring concrete:

Hanging device
It is used when transporting concrete mortar over a short distance with a shift to the site of the future foundation. To build this mechanism, you need to take a rope and attach a tray to it using cables threaded through a couple of blocks. One end of the rope is tied to a column or pole. A weight is attached to the other and left on the ground. The load should also be hung on the edges of the cables so that it is convenient to adjust the degree of inclination of this mechanism.
If a massive foundation is being laid for a large project, a fixed angle of inclination of the concrete conveyor should be installed. This can be achieved by increasing the height of the tower or installing additional columns. Actually, the mixture from the central tower will be transferred to these additional pillars.

Gutter structures with jibs
Diagram of a trench for pouring concrete.
Such a device is a mechanism in which the lower edge of the tray is attached to a jib - a lattice structure made of metal, one edge of which rests on the lower slide, the other is connected to the upper ones by means of a lifting cable. To maintain stability of the angle of inclination of the gutter, the lower edge of the structure is attached to the ground using cables. This device is used when delivering concrete composition to the formwork at a distance not exceeding 60 meters.

Purpose of concrete trays
Such a structure is intended for pouring mortar into the formwork of the future foundation of the building. From the concrete mixer, the mixture is supplied through a chute to its destination. However, if concrete is poured at the same point, then due to the uneven placement of the mixture, a flat surface of the designed foundation will not be obtained.
In this case, beware of delamination in concrete, when the watery part of the solution flows into the far corners of the formwork, and the denser part remains at the pouring point. By making mistakes when supplying the concrete mixture using a special tray, you can create a low-quality foundation that will soon begin to deform.
Therefore, be sure to create conditions for the smooth movement of the concrete mixer around the construction site so that there is access to any corner of the future structure. If in some places this is not possible, the length of the gutter should be increased in order to reach hard-to-reach corners.

Preparation of materials and tools for creating a gutter
When producing a transport mechanism for a concrete composition, pay attention to some points:
- This device must be in close contact at one end with the mixer, at the other with the formwork, thus connecting them.
- Install the device with a certain angle of inclination so that it is easier for the concrete under its own weight to flow down the gutter into the formwork.
Tools that may be needed at work.
To create such a mechanism, you will need the following tools:
- hacksaw;
- roulette;
- hammer;
- screwdriver;
- square;
- Bulgarian.
To do this you will need to prepare the following materials:
- board measuring 2.5/12 cm;
- a piece of polyethylene, linoleum or tin;
- timber or block as a support;
- nails (you can use screws).

Tips for making troughs for pouring concrete mortar
Before starting the production of a concrete delivery tray, it is worth paying attention to some conditions regarding setting the correct angle of the structure. The degree of the established inclination must be stable and the same throughout the entire working process. As the slope decreases, the flow of the concrete solution slows down . The consequence of this may be premature hardening or clogging of the mixture.
Pouring concrete through a chute into the formwork.
If the angle of inclination of the gutter, on the contrary, becomes even greater, the speed of transport of the solution inside the formwork will increase. This is fraught with the disintegration of the mixture into different parts, which can lead to a significant deterioration in the quality characteristics of concrete. The foundation will lose its performance qualities, become fragile, vulnerable and short-lived.
The angle of inclination for installation of the gutter structure is selected taking into account the level of supply range of the concrete mixture and its density coefficient. For liquid solutions conveyed over a shorter distance, a small level of inclination is permitted. If the composition is sufficiently dense or it is delivered over a long distance, the angular degree of the tray should be increased as much as possible in order to speed up the pouring process and not deform the structure due to the weight of the concrete mass.
The uniformity of the concrete composite is influenced by the shape of the gutter structure. A long, narrow tray, made with your own hands, during the delivery of the solution contributes to a closer connection of its grains. At the same time, the trench should be made quite deep to prevent the concrete solution from overflowing over the edges of the tray while pouring the foundation.
If the manufactured device transporting concrete from the mixer to the formwork turns out to be too narrow, it must be strengthened with horizontal crossbars. This will protect the structure from deformation during the thrombotic process of the concrete mass. If you want to give the structure greater strength, you can increase its hardness by means of corners attached to the tray perpendicularly. The length of such fasteners must correspond to the width of the gutter.
Today, similar mechanisms for laying foundations are produced from 3 to 15 meters in length. Such devices, as a rule, are used for more global purposes - in the construction of large-scale commercial, often multi-level structures.
Under private construction conditions, shorter (up to one and a half meters), convenient gutters are suitable, which are quite possible to make with your own hands. Its weight also depends on the footage of the tray. The longer the structure, the heavier it should be. This will protect the solution conveyor from bending under the weight of the mass entering it.

Concrete mixer trucks (mixers)
What is the volume of mixers (concrete mixer trucks)?
In practice, most often - 5 and 7 cubes, machines with 4 and 6 cubes are less common, somewhere there are even very small mixers with a volume of 2 cubes. Outside the city there are often narrow roads with closed turns, and many places cannot be reached by cars with a capacity of more than 5 cubic meters.
In the city - from 7 cubic meters and above. The main reasons why there are no small mixers:
- due to large volumes of one-time deliveries, it is unprofitable to keep small mixers,
- Small mixers are most often not new, have toxic emissions, and with them there is a greater risk of getting fined.
How much does a mixer with concrete weigh (loaded)?
The weight of 1 cubic meter of concrete is 2.4 tons, the weight of a 5-cubic-meter mixer is 11 tons, and a 7-cubic-meter mixer is a little over 12 tons. That is, a loaded 5-cubic mixer weighs 23 tons, a 7-cubic mixer weighs 29 tons.
What length are the sleeves of mixers?
Usually - from 1.5 to 2 meters.
If additional accessories are used, they may be the property of the driver who installed the gutter himself and may require additional payment for its use. The website of the mixer manufacturer Tigarbo shows the following photo:
The process of creating a trough conveyor for concrete mass
Jet chute diagram.
It is not at all difficult to build such a mechanism with your own hands. This is a simple process that does not require professional skills and abilities. First, use a saw to cut the board, adjust it to the dimensions of 2.5 by 15 cm, and knock down a shape resembling the letter “P.” The sides of this structure must be high so that the concrete solution does not stagnate during transportation.
To facilitate the flow of the solution along the tray, the entire inside of the structure must be covered with smooth materials: polyethylene, tin or linoleum. This will ensure better sliding of the solution and reduce its adhesion to the bottom and walls of the conveyor.
After making the trench device for pouring the foundation, it is placed in the required place, supported by four supports. The role of such supports can be perfectly fulfilled by gas silicate or other monoliths that can protect the means of transporting the composite from collapse.
You should know that inside elongated open-type structures, a specific percentage of moisture evaporates from the concrete mixture, thereby disrupting the homogeneity of the solution. Therefore, such transport mechanisms are used only at private construction sites.
When laying foundations for industrial purposes, gutters are used, constructed in such a way that at the bottom of the device, before entering the formwork, the concrete passing through the tray is constantly mixed. This is done with the help of a special trunk pipe, reminiscent of a funnel, through which the solution passes.

Design and operating principle
The technological process for producing concrete can be carried out using gravity or forced methods.
Gravity method: a pear-shaped container constantly rotates, maintaining the mixture in a liquid state, prevents loss of homogeneity and separation of the material, protects from harmful weather and climatic factors and prevents losses.
To load and unload the solution, 2-way screw blades are located inside the drum, operating on the principle of an Archimedes screw. When the elements rotate in one direction, cement and water with different fillers or ready-mixed concrete move towards the center of the mixer; when the movement changes, the solution is pushed out.
The rotating mechanism moves the tray 180° horizontally and 60° vertically.
Using a hydromechanical transmission, the drum rotates smoothly. The operating pressure in the system is 20-22 MPa.
In the forced method, the drum does not move, only the internal blades rotate.
The automixer device looks like this:
- chassis;
- dosing and washing tank;
- mixing drum;
- loading hopper;
- unloading bunker;
- folding tray;
- swivel mechanism;
- special equipment controls;
- control and measuring instruments.
To conveniently supply concrete to the site, use:
- gutters;
- pipes, sleeves;
- pumps;
- conveyor belts with unloading up to 14 m.
The telescopic boom increases the solution supply by 60 m.
