What is the difference between the replacement method and the soil replacement method, and what is t

There is no difference between the replacement method and the soil replacement method, it is the same concept.

The replacement method is also known as the soil replacement method. The so-called soil replacement method refers to the removal of soft soil within the scope of the roadbed, backfilling with stable soil and stone, and compacting or tamping. In highway construction, it is generally used to excavate and replace natural gravel, that is, within a certain range, the silt soft soil that affects the stability of the roadbed is excavated with an excavator, and the natural gravel is replaced, and the depth of excavation and replacement is within 2m, and the method of layered filling, layered compaction, and layered detection of compaction degree is adopted.

So as to change the bearing capacity characteristics of the foundation, improve the resistance to deformation and stability. In the process of refilling, the particle size, content and gradation of the stone in the natural sand and gravel should also be fully considered, and it is best to do test and detection to avoid settlement caused by inability to compact.

It is difficult to clearly demarcate the boundary between shallow treatment and deep treatment, and it is generally considered that the scope of shallow treatment of the foundation is roughly within 5m below the ground. The use of shallow artificial foundation not only depends on the magnitude of the load value of the building, but also is related to the physical and mechanical properties of the foundation soil to a greater extent. Compared with deep treatment, shallow foundation treatment generally uses relatively simple process technology and construction equipment, and consumes less materials.

The replacement method is to prepare for the improvement of the bearing capacity of the building foundation, and the scope of the soil replacement method is very wide, such as the subgrade slope soil change, in order to better plant turf; The replacement of soil behind the retaining wall is to make the retaining wall more stable and eliminate the influence of unforeseen earth pressure.

To be precise, the soil replacement method belongs to the replacement method. Because the replacement method can change the soil, it can also change other media such as stones. Personal opinion.

During foundation construction, the soil layer that can not meet the requirements of mechanical properties is excavated, and the soil layer that meets the requirements is replaced with the method of necessary treatment.

Summary. Hello dear, the thickness of the planting soil is controlled at 60cm. The planting soil should be loose surface soil, the soil permeability is good, there can be no construction waste and grass roots in the soil, the stone content in the soil is less than 10%, the diameter of the stone is less than 15 cm of mudstone, and the sandstone is less than 10 cm.

Hello dear, the thickness of the planting soil is controlled at 60cm. The planting soil should be loose surface soil, the soil permeability is good, there can be no construction waste and grass roots in the rolling soil, the content of stones in the soil is less than 10%, the diameter of the stone is less than 15 cm, and the sandstone is less than 10 cm.

It is the replacement of the building building.

Good. The replacement cushion is suitable for the foundation stacking and dismantling of the shallow soft soil layer or uneven soil layer. According to the comprehensive analysis of the building shape, structural characteristics, load properties, site soil conditions, construction machinery and equipment and filler properties and other comprehensive analysis, the design of the replacement cushion should be carried out, and the construction method should be selected.

For the replacement cushion with a large amount of engineering, the field test should be carried out according to the selected construction machinery, replacement materials and soil conditions of the site to determine the compaction effect of the replacement cushion and the construction quality control standard. The thickness of the replacement cushion should be determined according to the depth of the replacement of weak soil and the bearing capacity of the underlying soil layer, and the thickness should be.

After digging out the soil within a certain range of the foundation, replacing it with sand, stone and other materials, and only tamping (or compacting and compacting) in the layer, the foundation treatment method of the bearing layer as the foundation is the shallow treatment method of the traditional trillion car.

Answer] :d methods of artificial foundation treatment mainly include: compaction method, soil replacement method, chemical treatment method, piling method, etc.

When the upper surface part of the foundation is a weak soil with low bearing capacity (such as silt, miscellaneous soil), all the weak soil layers can be dug up and replaced with hard soil (or sand and gravel on the pad, or sand and gravel mixture prepared according to a certain comparison), and the method of the front height is called the method of changing the soil and changing the wisdom of the ruler.
