Can abundance and simplicity be the opposite

Reverse filtration mechanism. When water flows through the geotextile in the soil, the water can pass smoothly while the soil.

The phenomenon of particles being retained is called reverse filtration. Water flows from fine-grained soil in the soil.

Coarse-grained soil, or the escape point where water flows out of the soil from inside to outside the soil, needs to be installed.

Reverse filtration measures, otherwise the soil particles will be taken out of the soil by the action of water flow.

Unfolding will lead to soil destruction. Geotextiles can replace hydraulic works.

Natural filter materials such as sand and gravel used in China are used as filter layers. Geotechnical.

The main advantages of fabric instead of grit and other granular filter layers are: simple construction and cost.

Low weight, light weight, convenient transportation and abundant resources. Used as a reverse filter.

Geotextiles are generally non-woven (non-woven) geotextiles.

2 2 Reverse filtration design.

In hydraulic engineering, the main one that produces seepage deformation and leads to the destruction of the foundation.

It should be located at the permeable boundary of the seepage, and it is generally advisable to set it in consideration of its safety.

Filter layer. The design of the filter layer should meet 3 elements: Each layer of sand and gravel.

No movement should occur; Finer layers should not pass through coarser layers.

granular voids; Protected soil pellets, except for very fine particles, are not.

It should be carried with the seepage with the filter layer, and its very fine particles should be carried away by the seepage.

No silting of the filter layer.

See how you understand it.

Sufficiency: more than enough to meet the needs. The word generally refers to things.

Sufficient: 1 is enough, 2 as much as possible. This word is mostly used for abstract things. If well prepared.

The question of human value is as simple as that. What is the answer to a positive life, there is an indispensable point, we are all equally pitiful. Because I've never had him return to Antarctica with his equally experienced teammates.

The Central Powers, also known as the Anti-Fascist Alliance, were an alliance formed by some countries (eventually 57 of which broke away from the Axis powers) after the outbreak of World War II to resist the aggression of the Axis powers, and they were also the opposing camps of the Axis powers. Most of the reasons the Allies formed and joined the Allies were because they had been invaded by the Axis Powers or because they feared that the Axis Powers would control the entire world.

First, forty is not confused, the heart is enriched (in terms of the meaning of life), and after more experience, I naturally feel that I have recognized myself and the world clearly, so the world is "simple".

Second, the abundance of the heart means that you know more knowledge, you know more about the world (and I mean the knowledge aspect), so you feel that the world is simpler, because there are relatively fewer parts that you don't know!

First, increase the activity of muscles, so that most of the muscle fibers of the muscles are quickly put into exercise.

Second, it increases muscle ductility and reduces the strain, tear and rupture of muscle fibers and ligaments during exercise.

3. Increase the range of motion of the joints and improve the quality of movements.

Fourth, flexibility stretching after a lot of exercise can reduce delayed muscle soreness (after a lot of exercise, such as frog jumping, it doesn't hurt at the time, it starts to hurt in about 24 hours, it hurts most in about 48 hours, and it starts to slow down in about 72 hours), which is the latest proven effective way to reduce exercise fatigue.

The significance of stretching is to get the muscles out of stiffness and adhesion, avoid muscle compensation, joint compensation, so as to return the muscles to their original state, so that the body movement back to the most correct function, so that muscle gain, ** will become the simplest job! [Stretching is not a massage, nor is it a leg stretch] I have heard others say that stretching is like a massage, it is much more complicated than massage The direction and balance of muscles, the texture of the fascia and the judgment of compensation all need to be judged by the stretching coach In addition to the needs of the profession and strong physical strength, the compensation of muscles may make our training effect sluggish, and if the posture is not corrected, it may make us go deeper and deeper in a training cycle.

1. Improve blood circulation.

2. Discharge lactic acid accumulation.

3. Prevent muscle strain.

4. Adhesion of muscles.

5. Increase the flexibility of the body.

6. Relax the muscle fascia.

7. Improve muscle lines.

8. Improve muscle function.

9. Avoid sports injuries.

10. Improve the body's endocrine disorders.

11. Like some people who exercise or walk regularly, there are many small pimples in the deep muscles of the legs, which can be resolved by stretching and relaxing.
