Strengthening the coastline is relevant for those living near water bodies. The beauty of the type of building located near the water affects its value. Strengthening is also necessary in order to avoid subsidence and collapse of the soil, washing, when the internal soil is gradually carried away by the current and can suddenly get out from under your feet. Coastal instability is also an undesirable phenomenon for plants. The optimal solution is to strengthen the coast with larch, which will provide a durable and presentable result.
Fortification Choice
Types of fortifications:
1. For a gently sloping coast of great length, stone fastening of various sizes is suitable. The angle of the shore should not exceed 20 degrees. Before laying the material, so that it does not immerse in water, lay the geo base (mesh, textiles, grating).
2. The bioengineering method, which consists in planting plants with a developed root system, is suitable for rivers whose flow rate does not exceed a meter per second. This is a lengthy and relatively expensive method.
3.
Strengthening the coast with larch is a universal method of giving strength to a structure of any shape and length. The quality of this type of wood dominates many others. Facing piers, moorings, and finishing hydraulic structures are popular areas of application for larch. Long-term exposure to moisture, seasonal changes and the influence of temperatures are the factors that give rise to the use of the material in order to protect the soil from landslides and erosion.
Larch: material benefits
For several centuries, coastal reinforcement has been practiced with this material due to the numerous advantages of larch:
- moisture resistance: 6thanks to the gum in the composition of wood when water enters, rotting does not occur;
- resistance to damage by insects: impregnation with resin with gum repels any pests;
- unsurpassed durability (above oak, up to 110 units), allowing to exploit larch accessories for 50 years or more;
- resistance to deformation: any mechanical impact will leave a mark on wood, excluding larch;
- resistance to temperature differences allows you to operate larch in any climate zone;
- accessibility and ease of manufacture, as a result of which a beautiful and reliable fastening justifies itself from the financial side (cost, installation);
- larch is environmentally friendly in comparison with concrete or metal, which positively affects the animal and plant environment;
- the process of building a fortification takes place with a minimum of costs, without requiring heavy equipment;
- aesthetic properties favor larch, outperforming other materials.
Technology
The technology for strengthening coasts with larch is as follows:
1. The bars are set to the required depth, combining with brackets.
2. The installation depth is determined based on the type of soil, the characteristics of the load, the type of fastening, the volume of water.
3. The resulting wood layer is attached to reinforced concrete piles of the coast using stretch marks.
4. The next step is the thorough sealing of the material from the shore. Piles are covered with soil to the top.
The peculiarities of coastal strengthening by larch are that larch is an optimally acceptable material that performs the functions of fastening and decoration for natural and artificial reservoirs with a moderate current and a steep slope.
Despite the impeccable properties of wood, it is impregnated with an antiseptic before use.
Construction larch piles are selected of the same size and with slight deviations, 1.5-6 m long. Logs from 4 m are used for machine installation. Their diameter is 10-22 cm.
The height of the reinforcing wall depends on the size of the building material and the type of slope. The logs are tightly fastened with reinforcing anchors without the formation of gaps and are drilled deep into the ground. Outside the logs, the shore is additionally trimmed with geotextile. After installation, the ends of larch piles are trimmed and ground.
Regarding the price, strengthening the coast with larch in the capital costs about 9 thousand rubles per meter, and the method is preferable to the rest, especially with regard to artificial reservoirs, which at all times delight the owners with natural beauty.
Mounting Options
Piling is carried out in two ways:
- manual installation;
- with the involvement of technology.
The choice of option depends on the type of reservoir and its location.
The following factors are relevant:
- log length;
- type of soil at the place of work;
- fullness of the reservoir;
- the ability to drive to the water.
When strengthening the shore, it is necessary to monitor the tightness of the logs, as well as use fasteners.
Manual way
The prerequisites for strengthening the shore with larch by hand are a small pond, the impossibility of access of construction equipment. A necessary condition for this is the discharge of the water level below the plane of the work performed. The advantages of this method in a more tight fit of logs, high quality performance, affordable cost of services. Disadvantages - more time is required, when implementing a project, water has to be discharged, the type of work is related to the soil, which is a laborious process.
Machine mode
Features that speak in favor of a mechanized mounting option are a large object, as well as the ability to bring construction equipment to it.
Advantages of the method:
- short production time;
- no water discharge required;
- minimum earthworks;
- high efficiency of work.
Of the shortcomings, the following should be highlighted:
- loose fit of logs forming cracks between themselves;
- execution method requires free space;
- lower quality of work.
It is better to entrust the carrying out of measures to strengthen the coast with larch to professionals who will approach the task with knowledge of the matter and complete it as soon as possible.
