To prevent soil subsidence, shedding of the shore of the reservoir, loss of its original shape and shape, it is advisable to conduct shore-strengthening measures in a timely manner. If the territory of the site has access to the river, then its slope may collapse under the influence of the current, waves, and torrential flows. About how preventive work is carried out in order to protect an artificial or natural reservoir from destruction - further in the article.
The choice of material to strengthen
Wooden piles made of larch, oak, pine, acacia have been used in the design of a steep coast since ancient times. These rocks are characterized by high strength. The lifetime of a structure made of such a tree is almost half a century. Specialists prefer to use East Siberian larch.
Did you know? Pile structures of Venice, cities on the water, made of larch. This fact is documented in the work of the Italian historian Tentori back in XVII century.
The wood of this breed is able to serve for a longer time due to its increased resistance to soaking and decay processes - over time it only becomes stronger. The structure of larch logs is elastic, solid, twice as dense as pine, and contains a large number of resins. It is these natural properties that provide protection against aggressive environments. The material is more expensive compared to common types of wood, but the costs are quite justified due to its advantages.
Strengthening the coastline prevents pond overgrowing with reeds. Larch logs, being in the water, tolerate even the most severe frosts and do not require additional care during the operational period. The ecosystem of the reservoir remains holistic.
Reinforcement technology
Framing a steep shore with the help of machined trunks selected in diameter has a spectacular decorative appearance, especially if there are wooden buildings nearby. Such a decision does not violate the existing landscape composition, gives the pond a natural charm. This method is used provided that the soil around the reservoir is not characterized by friability and mobility. Installation of piles from environmental material is performed by special equipment or manually. For shore protection of a small reservoir, lightweight handheld dredgers of a compact size are quite enough. They are manually moved around the country.
Did you know? Larch is a long-lived tree. It can reach a height of 50 m with a trunk diameter of up to 1 m. Andeven nine hundred year olds are known.
Heavy larch logs. The technology for strengthening the slope of the pond provides for the immersion of trunks in the soil to a depth of 0.5 to 2.5 m (this indicator is affected by the installation method, type of soil and the size of the reservoir).
For this purpose, on large objects:
- wash clay and sand with a water jet;
- Pit drilling is used to hammer logs;
- vibratory hammer immersed bars.
Manual installation of trunks is different: experts change the position of the logs, perfectly fit them to make a row. Then the bars are fixed, as a result of which a strong wall is formed. When shore protection is not damaged landscape composition, but this work requires a lot of time and effort. Self-installation of beams will take about a month for the owner of a small pond and his assistants. Masters with experience carry out similar work much faster - within 5-7 days.
The technology of shore strengthening with oak or pine piles is no different from the use of larch, with the exception of the durability of the structure. Additional processing of wood with water-repellent impregnation is ineffective: over time, the material is damaged as a result of contact with water and from the invasion of pests.
You can use larch shields to strengthen the slopes of the pond. They are made by knocking boards into a single structure and mounting them on piles. The cost of such shields is 25% cheaper than using beams. The work should be based on accurate calculations of soil pressure, taking into account the characteristics of the reservoir. Independently strengthening the shore of the pond with the help of shields is carried out, strictly observing the technology, otherwise the structure may skew, the earth will squeeze the lining and have to do it all over again.
Work stages
Shore protection measures are being carried out simultaneously with the arrangement of the foundation pit of the future artificial reservoir. Timely preventive work will prevent the destruction of the soil, clouding of water, accumulation of sludge at the bottom, as well as the opening of non-aesthetic walls of the reservoir, covered with a film.
Refuse to carry out construction work in the winter due to restrictions due to low temperature conditions. Spring thawing of the soil also negatively affects fixed heavy logs: they can shift, and will have to be strengthened again. Therefore, experts prefer to engage in the strengthening of ponds, starting in May and ending in September. Bank protection of the river is carried out when the water level drops to the maximum - in the autumn months.
Important! If there are signs of shore destruction, you should start preventive work immediately. Deferring significantly increases future expenses: loose soil can suffer even more from nearby heavy rainfall.
Before embarking on a preventative work, it is necessary to evaluate a number of factors that have a direct impact on shore protection procedures:
- size of the reservoir, features of its use;
- soil characteristics: the prevalence of clay or sand;
- the height and slope of the slope;
- shedding of land above water or at the bottom;
- the period of operation of the facility;
- duration of coastal destruction;
- climatic conditions of the area, for example, the presence of sharp temperature changes and the intensity of precipitation, the depth of freezing of the soil;
- the availability of funds.
The data obtained will allow to predict the rate of damage and calculate the necessary time for preparatory work for the immediate implementation of bank protection. In some cases, you will have to act as quickly as possible to avoid possible negative consequences.
By the type of soil and the parameters of the reservoir, you can determine the size of the logs, the required depth. Getting to the task, first completely pump out water from the pond and work on the problem area of the coast. Piles of larch are mounted along the water line. This is an expensive breed, but for shore protection you can use cheaper pieces of logs. The soil of the coast is covered with geopolitical, then wooden supports are installed.
Important! In the absence of financial opportunities for full restoration work, use any available stones or old car tires to temporarily strengthen the damaged area.
Geotextiles prevent the filling of gaps between the logs with a sand-and-sand mixture. Piles are mounted tightly in the form of a reliable shield that will prevent the processes of erosion and shedding of the soil. Installation is carried out by high pressure pumps. This equipment does not destroy the coast, so such construction work will not damage the already sanitized territory. The appearance of the shore, fortified by this method, is characterized by accuracy and attractiveness.
To preserve a neat and beautiful coastline, protect buildings, ensure safety at the exit to the water, reinforce the slopes of the pond with a log. You can create strong borders yourself, using improvised means, with a minimum of expenses, or use the services of a specialized company. The price of installation work from larch wood: from 9 thousand rubles. per linear meter along the coast. Cost includes delivery of material in the region.
