What are the main factors that destroy the revetment?

There are no more than 2 causes of destruction: man-made destruction and natural destruction. There should be many reasons for natural damage: such as water seepage of the waterproof layer, weathering of the stone, rupture caused by excessive temperature difference, and so on.

Factors influencing brittle failure.

1.Chemical composition.

2.Metallurgical defects (segregation, non-metallic inclusions, cracks, layering) 3Temperature (hot brittle, low temperature cold brittle).

4.Cold work hardening.

5.Aging hardening.

6.Stress concentration.

7.Three-way principal stress state with the same number.

There are two types of failure of steel: plastic failure and brittle failure.

The causes of damage include water seepage of the waterproof layer, weathering of the stone, and rupture caused by excessive temperature difference. The garden revetment is an engineering structure that plays a protective role, which is composed of a foundation, a wall, a roof, etc., and is required to be firm and stable when building.

The revetment is mostly used as a measure to strengthen the foundation by piling or firewood raft bedding. Solid large stones are selected as blocks, and a widened layer of ash soil is also used as the foundation to build the revetment on it. Revetments are best built directly on solid soil or rock foundations.

If the foundation is weak, foundation treatment is required. In recent years, revetments have been constructed in gardens in southern China, and the method of widening the foundation is often used to reduce or eliminate foundation treatment works. Revetments are often used as foundations for strip stone, block concrete, concrete or reinforced concrete.

Type:

According to the cross-sectional shape, the garden revetment can be divided into two categories: whole form and natural type.

For large water bodies, water bodies with large wind and waves, large changes in water levels, and water bodies in gardens that are basically regular layouts, the whole form of straight revetment is often adopted, and the shore wall is shaped with stone, brick or concrete.

For small water bodies and small parts of large water bodies, as well as water bodies with stable water levels in natural gardens, natural mountain and rock revetments or gently sloping revetments with vegetation are often used. The natural mountain stone revetment can be made into rocks, rocks, cliffs, Xiu and other shapes, and take the form of stretching up and down, flat and high hanging.

There are four main factors that undermine the revetment. 1. The uneven subsidence caused by the uneven subsidence caused by the different foundation strength and the load of the shore roof of the pond potato spring bottom, caused longitudinal cracks and even partial collapse of the revetment.

2. In the case of low water depth in cold areas, the foundation may be deformed due to frost heave.

3. The piles made of wooden stakes love to corrode or decay due to the destruction of some animals under the water.

4. In areas with high groundwater levels, the number of Qinai will produce buoyancy and affect the stability of the foundation.

Below the river floor, the structures that protect the river bank (prevent the river bank from collapsing or scouring) are called revetments, and the facilities that protect the water bodies in the garden.
