Description

DISCHARGE PIPE, PLATE AND PIPE SYSTEM COMPRISING THEREOF WHICH ARE

USED IN DRAINAGE PROCESSES

Technical Field

The present invention is related to discharge pipe, plate and pipe system comprising thereof, which are used in drainage processes in order to discharge underground water in the sectors such as agriculture and construction.

The present invention is especially related to a pipe system, which comprises discharge pipe, plate having inlet section that creates sedimentation area around said discharge pipe and enables water inlet, and at least one set positioned at certain distances on the plate and enables the water that will be discharged, to rise vertically.

State of Art

Rainfall affects the agricultural activities negatively, because water level arises under the ground near lake, river and sea beds. Arise of water table causes undesired conditions such as salinization on the soil surface. Therefore, drainage processes are performed in agricultural reclamation and construction projects in order to lower the water table and thus, to discharge the excessive water in the soil.

Controlling the underground water table has vital importance in terms of agricultural reclamation. Enhancing the soil structure for the growth of targeted plant species is possible by controlling the underground water table. Irrigation and drainage are of utmost importance in terms of creating a controllable agriculture area by lowering or raising the water table up to targeted levels.

Drainage systems in soil reclamation have changed and improved thanks to improvements in the industry during the historical process. Especially in the recent years, different studies and applications have been conducted in order to enable the drainage pipe to operate under the ground for longer time without being blocked.

In the earlier stages, deep water channel were formed in the areas where soil reclamation was required in order to discharge then excessive water in the soil, because pipes made of tiles and pipes made of plastics were not provided, and excessive water was tried to be removed from the soil by means of said channels. Then, tile pipe started to be produced. As the body of tile pipe can absorb water, said pipes have been used in drainage processes for a certain period of time.

Together with developing technology, pipes made of plastics have started to be used in drainage processes. Therefore, soil reclamation has been tried to be achieved by digging peripheral holes on the pipes, laying said pipes under the ground, and removing the excessive water in the soil. However, the pipes have started to get blocked due to the fact that sand, silt and plant roots penetrate through the holes of plastic and perforated drainage pipe in time. Thus, pipe laying process has been tried to be performed at an area deeper than the plant roots.

Another method developed for drainage process is surrounding the pipe with sand and gravel while the pipes are being laid. However, the efficiency is higher at the first phases after the pipes are laid down, but it decreases in the upcoming phases, in time, said system faces many disadvantages, because the gaps between sand and gravels are filled with particles dragged by water under the ground. In said laying, drainage pipes need a regular maintenance and cleaning.

Another method used for drainage application is wrapping geotextile materials around the pipe in order to prevent silt and sand penetration. One of the applications found in the search relating to the subject is the application numbered US2011262682A. Said application discloses a geotextile tube obtained from weft, warp and nonwoven fibres and used for filtering the undesired materials in the drainage systems. However, when said applications are performed, silt, sand and plant roots reach the pipe again and block the pipe. Even at least one blocking experienced prevents the function of the pipe completely. As a result, the required cleaning process causes additional costs and proper drainage cannot be achieved, as the laid areas are broad.

Another disadvantage in the state of art is that the process must be performed at a deeper section in order to get away from the plant roots while drainage pipe is being laid; therefore, the level of water table targeted from the agricultural maintenance is not compatible with the level of water table. The penetration of plant roots, silt and sand still leads to problems due to the water table level in terms of drainage. The method called French Drain in Europe and the systems used in the state of art are cannot solve said problems.

In summary, the problems in the drainage pipe systems are as follows;

- The accumulation of silt in the pipe causes blocking. - Blocking is experienced, as plant roots penetrate into the pipe.

- The laying depth is determined in accordance with the plant-root structure of the area and impermeable layer and thus, the desired depth cannot be laid all the time.

- Laying with sand-gravel causes the loss of natural resources and transportation costs.

- When fibre geotextile coating is taken into consideration, additional costs arise due to the additional materials used and the pipes are damaged excessively because of lifting-lowering more than required in the coating process.

The reason of plant roots for penetrating into the present drainage pipes is as follows: When drainage pipe is laid laterally under the ground, the water table falls below the pipe due to some reasons such as seasonal conditions and water movements. In this situation, however, water residues within the pipe leak into the soil through the peripheral holes around the drainage pipe. Humidity occurs in the soil due to the leakage and plant roots turn towards the humid area in dry spells. The roots turning towards humidity penetrate inside through the holes in time. The patent application numbered DE3534499A1 is related to prominences arranged on the outer wall of the pipe to prevent root penetration through the pipe holes in the drainage system.

Moreover, regular and homogeneous efficiency cannot be achieved from the systems in the state of art. The system which is applied by pouring sand and gravel on the pipe, cannot achieve the same efficiency in each length, because sand and gravel accumulation is not equal around the pipe in each meter. In drainage applications with geotextile, however, different effects are observed in each area throughout the drainage pipe, because the perforations of geotextile are not distributed homogeneously due to production processes.

Silt and other particles penetrate into the drainage pipe in the laying of drainage pipe with sand, gravel and geotextile and thus, additional regular cleaning is required.

One of the main problems experienced in the state of art is that the required water in the soil is drained in dry and less rainy periods. As the holes around the pipe are open to external environment directly, even if the rainfalls in said periods do not increase the water table, they lead to the discharge of water penetrating into the soil by penetrating into the upper holes of drainage pipe. Therefore, the water required by the plants is drained.

As a result of the drawbacks mentioned above and the insufficiencies of the present solutions regarding the subject, an improvement in the related technical field is needed. Objects of the invention

The present invention is related to drainage pipe system that meets the abovementioned needs, eliminates all the disadvantages and offers some additional advantages. The primary object of the present invention is to prevent the penetration of the elements such as plant root, silt and sand, which may block the system thanks to the system comprising new plate and pipe developed. Leakages are prevented thanks to the fact that hole is not provided at the lower section of perforated drainage pipe and a plate is provided on the section with holes. Therefore, the penetration of plant roots turning towards the pipe system into the system due to leakage is prevented. Thus, the perforated pipe can be laid at the desired level under the ground. This, in turn, enables the planning of water table at desired level without measuring the length of roots in the agricultural activities easily.

Another object of the present invention is to achieve controlled formation of water table. It fixes the water table at the laying level underground in the area where it is laid. It does not discharge the water below the laying level; it removes the undesired water from the system when water table rises above the level of laid drainage pipe.

An object of the present invention is to enable the pipe to function for a longer time without being blocked thanks to the fact that other particles such as silt and sand do not penetrate into the pipe.

Another object of the present invention is to prevent additional costs and damage of pipe system thanks to the fact that the plate is coated on the pipe during applied-laid process.

A similar object of the present invention is to prevent an embodiment with unsteady efficiency by providing a structure that is homogeneous at every area of pipe system.

The present invention aims to eliminate the need for cleaning as plant root, sand and silt do not penetrate therein thanks to the structure of the invention.

Another object of the present invention is to maintain the water in the soil in dry and less rainy periods thanks to the drainage process performed only when the water table is high. Water saving is achieved thanks to the fact that a direct inlet of the water is not provided on the drainage pipe.

In order to achieve the abovementioned objects, a pipe system, which comprises discharge pipe, plate having inlet section that creates sedimentation area around said discharge pipe and enables water inlet, and at least one set positioned at certain distances on the plate and enables the water that will be discharged, to rise vertically has been developed in order to be used in drainage processes. In order to achieve the abovementioned objects, discharge pipe comprising at least two lateral holes on the right and left sides so as to form 135° angle at most according to axis x, has been developed.

In order to achieve the abovementioned objects, a plate which comprises at least one set that enables the water that will be discharged, to rise vertically, and on which, said set is positioned has been developed.

The structural and characteristic features and all the advantages of the present invention will be understood more clearly thanks to the figures given below and the detailed description written with reference to those figures; therefore, the evaluation needs to be done by taking said figures and detailed description into consideration.

Detailed Description of the Present Invention

In this detailed description, the preferred embodiments of the drainage pipe system (A) according to the present invention are described only for the subject to be understood better without any limiting effect.

The drainage pipe system (A) according to the present invention is generally related to a pipe system (A) comprising a discharge pipe (10), and plate (20) having inlet section (50) that creates sedimentation area (30) around said discharge pipe (10) and enables water inlet. Figures 1 and 2 illustrate overall and front views of the pipe system (A) according to the present invention.

Figure 3 illustrates a perspective view of the plate (20). Said plate (20) may be concrete, metal or plastic. Said plate (20) has the following features:

The sets (23) are positioned at certain distances on the plate (20). Figure 4 illustrates the lateral view of the set (23) formed on the plate (20). Said sets (23) comprise set recess (24) and set protrusion (25). The reason of said members for forming the set (23) is that the plate (20) that is produced in a straight manner and does not have enough flexibility when it becomes circular, is wrapped on the discharge pipe (10). While said plate (20) is being wrapped on the discharge pipe (10), the set protrusions (25) on the set (23) is positioned side-by-side and compressed. As a result of compression, set recesses (24) disappear and flexibility is achieved and thus, a circular form is obtained. The region between two sets (23) is called sedimentation area (30). In said area, the sets (23) serve as a wall and provide the vertical motion of water. Said sets (23) can be formed on the plate (20) by means of liquid silicon or rubber afterwards.

Thanks to said sets (23), water is sedimented within said sedimentation area (30) and can rise up vertically. Therefore, water sedimented from silt and mud rises up and flows into the discharge pipe (10). The sets (23) can be provided on desired distances throughout the discharge pipe (10). However, close positioning of sets (23) throughout the discharge pipe (10) enables the water to rise up vertically in the sedimentation area (30) because of the bevel of discharge pipe (10).

On the plate (20), there are protrusions (21) formed within sedimentation area (30) between the sets (23) in such a manner that the end of the protrusions extend through the discharge pipe (10). Said protrusions (21) both can be in different forms and are used in a circular manner preferably in the invention so as to extend through the discharge pipe (10).

Thanks to the circular protrusions (21) used, distance is formed between the plate (20) and discharge pipe (10) and a sedimentation area (30) is obtained. Said protrusions (21) are formed in a hot/cold manner by means of vacuum or thermoform technology.

The load distribution on the pipe system (A) is achieved on soils (40) with heavy structure thanks to the protrusions (21) formed. Figure 5 illustrates the view of soil (40) applying load on the plate (20). When the protrusions (21) are coated with sand, soil (40) and gravel, said materials are filled into the protrusions (21). Figure 6 illustrates the view of load distribution of the soil (40) applying load on the plate (20). Therefore, resistance is achieved in the flat sections that do not form protrusion (21) on the plate (20), and distance is formed between plate (20) and discharge pipe (10). Therefore, the plate (20) having high resistance is produced with a thinner material and costs are decreased.

In a preferred embodiment of the present invention, water splitter (22) on the plate (20) so as to be at the center and opposite the middle hole (11) of the discharge pipe (10). Water splitter (22) is the extension positioned at certain distanced on the plate (20) and formed in the shape of triangle bracket. As described before, it can be formed both at certain distances and in the shape of a single strip. The function of said water splitter (22) is as follows; when the residues that will accumulate at right and left side of plate (20) and discharge pipe (10), namely, in the sedimentation area (30), are required to be cleaned, pressure water is transferred through the discharge pipe (10) and hits to the splitter (22) by discharging from the middle hole (12) and is divided into two sides. Therefore, both of the sections are cleaned. The pressure water transferred through the discharge pipe (10) during cleaning process, is discharged especially from the middle hole (12) and hits to triangle splitter (22) and thus, turbulence is created. Therefore, silt and soil are removed and mixed with water and discharged by being received into the discharge pipe (10) through lateral holes (13). When said process is performed, sedimentation area (30) is cleaned and the service life of pipe system (A) is increased. The pressure water (A) transferred into said pipe system (A) can be divided into two thanks to the circular form of the plate (20) without water splitter (22). Therefore, the splitter (22) enables the water to be divided into right and left sides in a more effective manner.

In a preferred embodiment of the present invention, a separator (60) in the form of brush is positioned throughout the edges of the plate (20). The overall and detailed views of said separators are given in Figures 7 and 8. The function of separator (80) used is to filter the muddy water penetrating into the sedimentation area (30) through inlet section (50) and to minimize the penetration of foreign substances such as gravel into the pipe system (A). Moreover, it prevents the runny soil/mud from leaking into the sedimentation area (30) because of soil (40) pressure. Therefore, cleaning period is minimized and pipe system (A) has a longer service life.

A least one hole (11) that enables the water to pass from sedimentation area (30) to the discharge pipe (10) is provided on the discharge pipe (10) that is another member according to the present invention. Said hole is formed in a broad manner and enables the discharge pipe to be used in "U" form.

There are preferably three holes (11) in the invention. Figures 9 and 10 illustrate perspective and front views of the discharge pipe (10) and the holes (11) formed thereon. The water rising up in the sedimentation area (30) that remains between the sets (23), flows into the discharge pipe (10) when it reaches the level of hole (11). The middle hole (12) among the holes (11) is formed on the axis x at the center of the upper hemisphere of the discharge pipe (10). The lateral holes (13), however, are formed at the right and left sides of the middle hole (11) so as to be at equal distance and angle from the hole positioned at the center. Said lateral holes (13) at the right and left sides, can only be positioned on the discharge pipe so as to form 135° angle at most. Therefore, said holes (11) are configured so as not to intersect with the inlet section (50). However, angles of 25°-45° with respect to axis x are preferred angles for the position of lateral holes (13) for optimum life and sedimentation. Figure 11 illustrate a view of the discharge pipe (10) and the holes (11 , 12, 13) formed thereon with respect to axis X. The water that will be discharged rises above the holes (11) by being sedimented and arising in the sedimentation area (30). As water mobility is sometimes high in the soils (40) with light structure, water in the sedimentation area (30) rises up rapidly and exceeds the level of lateral holes (13). Therefore, water creates vacuum effect while it is flowing into the discharge pipe (10) from the lateral holes (13), because it does not take any air from anywhere. In this stage, middle hole (12) serves as ventilation hole in order to provide air inlet and accelerate the water flow through lateral holes (13).

In an alternative embodiment of the present invention, open-top discharge pipe (10) can be used instead of holes (11) on said discharge pipe (10). Said opening can be changed optionally and in accordance with the structure of soil, and can be positioned at a height so as to be covered with plate (20). Thus, discharge pipe (10) has a "U"-shaped form.

In a preferred embodiment of the present invention, the middle hole (12) provided on the discharge pipe (10) is configured broader than the lateral holes (13) on the right and left sides. The reason thereof is to facilitate the discharge of pressure water through discharge pipe (10) during the cleaning process of the abovementioned pipe system (A). Said middle hole (12) is positioned opposite the splitter (22) in order to facilitate the cleaning process and to distribute water. The width of the middle hole (12) can be equal to or lower than the widths of other holes. Even if middle hole (12) is not provided, system functions. Said middle hole (12) is a preferred embodiment especially in the soils with higher mobility, as it increases efficiency.

The plate (20) and discharge pipe (10) used in the pipe system (A) can be produced both separately and together. The plate (20) and discharge pipe (10) can be produced as a single block.

The general operation principle of the invention is as follows:

Water level rises between the plate (20) and discharge pipe. The water rising between the protrusions (21) that provides the load distribution of the soil (40) and increases the resistance of material, is sedimented in the sedimentation area (30) formed between the sets (23), and flows into the discharge pipe (10) through the holes (11). During cleaning process, however, the pressure water transferred into the discharge pipe (10) is divided into two by hitting to the splitter (22) while passing to the sedimentation area (30) through the middle hole (12), silt/sand deposits provided in the sedimentation area (30) at both sides are received into the discharge pipe (10) by means of pressure water and discharged through the discharge pipe (10).
