The reservoir in the suburban area brings pleasure in the case when its banks are securely strengthened and the mirror of the water remains clean. Take care of the comfortable condition of a pond or other body of water in advance. We will make a reservation at once: hydraulic engineering facilities for this purpose must have a certain assembly scheme and corresponding materials. How to properly strengthen the banks of the pond?

Why is it necessary to strengthen water bodies
Any artificial pond in the suburban area during the design and installation requires special measures aimed at strengthening the banks of the reservoir.
Strengthen the coast is necessary for miniature reservoirs with the area of the water mirror to 1 square meter, as well as water bodies with a large area of water. Correct biobalance of plants and microorganisms of the fortified banks of the reservoir will exclude the possibility of turning the pond into a sour puddle. By what methods and methods can you strengthen the shore with your own hands?
A good choice of building materials allows for reinforcement with the use of concrete, film, polymer materials and gabion structures. Measures on shore protection allow using such materials:
• Polymer sheet piling
• wooden piles
• a rock.
The variant of "strengthening" works should be made according to the results of hydrotechnical survey of soils, taking into account the structural features of fences or structures. Let's show that the main conditions of operation of shore protection are the load on the foundation.
Ways to strengthen the banks of the pond
The existing shore protection technologies are designed for the construction or reconstruction of a summer cottage. The possibility of washing the coastline with water or soil slumping forces us to look for the best option for strengthening. Work to strengthen the coast is laborious, so expensive.
There are the following ways to strengthen the banks of reservoirs on the site:
• with the use of anti-erosion mesh (cost about 650 rubles per square meter)
• with the use of plants and shrubs (cost 2900 rubles square meter)
• using a geogrid (cost 1400 rubles).
• using a reinforcing net of fine-mesh netting with filling with buta (cost 2900 rubles).
• using wooden piles (cost 1700 rubles)
• using dowels and shpuntin (cost 2000 rubles)
• using gabion constructions (cost 2900 rubles)
You can independently strengthen the shore of the reservoir. For this, it is necessary to develop a suitable project and select the necessary materials.
How to strengthen the banks of the pond
Strengthening the shore of the reservoir by their own hands depends on the type of shoreline.
if the shore of the pond is shallow
When the shore of the reservoir in the suburban area has a slope less than 45 °, then it can be strengthened by the roots of bushes or low trees planted in the ground. Over time, the plants of the shores of the reservoir will expand and provide for the strengthening of the shoreline.
Help can also geogrids filled with grass seeds for the lawn or flat modification of gabions - mattresses Reno. The consolidation process will consist of the stages: planning of the shore slope with its subsequent leveling, laying of the strengthening structure and giving it stability.
Geotextile spread on the prepared soil, removing the fertile layer. The geogrid is laid and reinforced with anchors with the fixation of individual modules in a checkerboard pattern.
To fasten the modules, a pneumostepple is used, the reinforcement is made with common anchors.
After strengthening, we make the bank of the reservoir. However, for water bodies with a significant bias angle, these methods are ineffective. Therefore, piles, dowels and large-sized gabion structures are used.
if the shore of the pond is steep or steep
When the coastline of the reservoir is vertical and solve the problem with the use of geogrids, it is inappropriate to use a more powerful reinforcement with the use of piles, piles and gabions.
use of dowels and piles of PVC
The most widespread in hydrotechnical works were reinforced concrete piles and PVC piles. What is attractive about the use of dowels and polymeric dowels? These are such positive qualities:
• No need for excavation, which reduces installation time
• Minimizes the process of subsequent maintenance during operation
• increased reliability and safety of the hydraulic structure.
However, the methods of installing the tongue (immersion method) require the use of special techniques for driving the coprod during vibration and burial. Schematically, the wall of reinforced concrete pile with an anchor consists of a sloping fastening, a monolithic shaping beam and a facing slab, as well as reinforced concrete pile, a drainage fill, a reinforced concrete box and an anchor plate.
Agree that this hydraulic structure will require certain knowledge and skills, so creating such a strengthening is difficult and expensive. In addition, reinforced concrete dowels are used in the case of transferring the degree of load in a weak ground. The pile foundation of wooden piles, combined constructively with the use of a grill beam, is capable of providing the necessary resistance to the coastal soil.
use of wooden piles
The scheme of application of wooden piles for bank protection includes crushed stone preparation, a prefabricated pile structure with a stubborn belt. For piles, preference should be given to the wood of oak and larch. An old and proven way to strengthen the banks using wooden piles will provide the building with strength for a long time.
use of gabions
The use of gabion (box-shaped retaining walls) can be confidently called the traditional method of bank protection in case of disturbance of the land by water erosion. Therefore, gabions are used for inclined, channel, shear and wave erosion of the shoreline.
Gabion design is able to withstand considerable resistance to static and dynamic loads, using reinforcing elements - the face of the gabion. The porosity and permeability of the gabion provide draining of the fill, excluding the costs of the drainage device.
Strengthening the coasts using gabion structures independently consists of the following:
• carry out general planning works
• the construction of gabions in folded form is laid out on a flat surface
• assembling the gabions of the required configuration and fixing the side surfaces
• carry out a bundle of corners of the structure with double turns with a pitch of 10 cm.
• assembled gabion structures are installed at the place of installation
• connect the gabions to each other and drive in the corners of the boxes the fixing rods
• fill the boxes with stones and compact the total weight
• pull the top cover and close the box using a wire.
Thus, a correctly assembled and assembled hydraulic structure will be able to provide an appropriate level of protection for the shoreline.
