The difference between composite foundation and composite pile foundation

Composite foundation refers to the natural foundation in the process of foundation treatment part of the soil is enhanced, or replaced, or in the natural foundation to set up reinforcement materials, reinforcement area is the matrix (natural foundation soil or improved natural foundation soil) and reinforcement two parts of the artificial foundation. According to the direction of the reinforcement in the foundation, the composite foundation can be divided into vertical reinforcement composite foundation and horizontal reinforcement composite foundation. Vertical reinforcement composite foundation is customarily called pile composite foundation.

Hello, what is a rigid pile composite foundation, Xinshen is a raft foundation system is made of reinforced concrete piles. 1. Composite foundation refers to the natural foundation in the process of foundation treatment part of the soil is strengthened or replaced, or in the natural foundation to set up reinforcement materials, the reinforcement area is the matrix (natural foundation soil) and the reinforcement of two parts of the artificial foundation. In the composite foundation, the reinforcement and the matrix are jointly and directly loaded together.

2. According to the direction of the reinforcement, it can be divided into two categories: vertical reinforcement composite foundation and horizontal reinforcement composite foundation. According to the different transfer mechanism of load slip mu, the vertical reinforcement composite foundation can be divided into three types: bulk material pile composite foundation, flexible pile composite foundation and rigid pile composite foundation.

Composite foundation, shallow foundation and pile foundation are the three common forms of foundation at present. A raft foundation system is made of reinforced concrete piles.

The applicable object and force point are different. According to the query real estate network, the difference between composite foundation and pile foundation:

1. The applicable objects are different: composite foundation is a way of foundation treatment, and pile foundation is a form of foundation for building buildings.

2. The stress point is different: the composite foundation is the soil with cement, lime and fly ash mixed to improve, the stress is the mixture of soil, the pile foundation is to drive concrete piles, and the stress is the pile.

Compound refers to the natural foundation in the process of foundation treatment part of the soil is enhanced, or replaced, or in the natural foundation to set up reinforcement materials, the reinforcement area is the matrix (natural foundation soil or improved natural foundation soil) and reinforcement two parts of the former brother artificial foundation. Under the load, the matrix and the reinforcement bear the role of the load together. According to the load transfer mechanism of the composite foundation, the composite foundation is divided into two categories: vertical reinforced composite foundation and horizontal reinforced composite foundation, and the vertical reinforced composite foundation is divided into three types: scattered material pile composite foundation, flexible pile composite foundation and rigid pile composite foundation.

In the pile composite foundation, the role of the pile is the main one, and the pile in the foundation treatment has more Qiaoling-like types, and the performance changes greatly. For this reason, it is more appropriate to divide the type of composite foundation according to the type of pile. However, piles can be classified according to the materials used in the piles to bend and the strength (or stiffness) of the piles after the piles are formed.

The pile body can be divided into the following according to the materials used in the pile

1) Loose soil piles such as gravel piles, sand piles, etc.;

2) Cement-soil piles, such as cement-soil mixing piles, jet grouting piles, etc.;

3) Concrete piles, root piles, CFG piles, etc.

If the pile body is based on the strength (or stiffness) of the pile after the pile, it can be divided into:

1) Flexible piles, bulk soil piles, belong to this type of pile;

2) semi-rigid piles, cement-soil piles;

3) Rigid piles, concrete piles.

The amount of cement in the semi-rigid pile will directly affect the strength of the pile. When the amount of incorporation is small, the characteristics of the pile are similar to those of flexible piles. When the amount of incorporation is large, it is similar to a rigid pile, for which it has dual characteristics.

The composite foundation composed of flexible piles and soil between piles can be called flexible pile composite foundation, and the others are semi-rigid pile composite foundation and rigid pile composite foundation.

In the pile composite foundation, the role of the pile is the main one, and there are many types of piles in the foundation treatment, and the performance changes greatly. For this reason, it is more appropriate to divide the type of composite foundation according to the type of pile. However, piles can be classified according to the material used to form the pile and the strength (or stiffness) of the pile after the pile.

The pile body can be divided into the following according to the materials used in the pile

1) Loose soil piles such as gravel piles, sand piles, etc.;

2) Cement-soil piles, such as cement-soil mixing piles, jet grouting piles, etc.;

3) Concrete piles, root piles, CFG piles, etc.

If the pile body is based on the strength (or stiffness) of the pile after the pile, it can be divided into:

1) Flexible piles, bulk soil piles, belong to this type of pile;

2) semi-rigid piles, cement-soil piles;

3) Rigid piles, concrete piles.

The amount of cement in the semi-rigid pile will directly affect the strength of the pile. When the amount of incorporation is small, the characteristics of the pile are similar to those of flexible piles. When the amount of incorporation is large, it is similar to a rigid pile, for which it has the dual characteristics of Lingkong.

The composite foundation composed of flexible piles and slag piles can be called flexible pile composite foundations, and the others are semi-rigid pile composite foundations and rigid pile composite foundations.
