underpinning the foundation of a house is a complex and expertly-required project that often requires a reinforcement plan based on the specific structure of the house, damage, reinforcement needs, and local building codes and technical standards.

First, determine the reinforcement plan

1, site investigation: a comprehensive inspection of the house, to understand the structural form of the house, materials, damage, etc., to provide a basis for the development of reinforcement programs.

2, design reinforcement scheme: according to the survey results, combined with the house function, reinforcement needs and other factors, design a reasonable reinforcement scheme. The reinforcement plan should specify the reinforcement position, reinforcement method, reinforcement material, and construction steps.

Second, construction preparation

1. Material preparation: According to the reinforcement scheme, prepare the required reinforcement materials, such as steel bars, concrete, steel plates, carbon fiber cloth, etc.

2, equipment debugging: check whether the construction equipment is in good condition to ensure that the equipment can operate normally during the construction process.

3, safety protection: develop a safe construction plan to ensure the safety of personnel in the construction process.

Third, reinforcement construction

The concrete methods of reinforcement construction are varied, and the following are several common reinforcement methods:

1, reinforced concrete reinforcement:

Add steel and concrete to key parts of the house structure (such as beams, columns, walls) to improve the load-bearing capacity and stability of the structure.

It can be carried out by strengthening shear walls, wrapping beams and columns, strengthening foundations and so on.

2, steel plate reinforcement:

Steel plates are added to the house structure to increase the strength and stability of the structure.

This method is suitable for the reinforcement of small load-bearing parts such as building walls and floors.

3, carbon fiber cloth reinforcement:

Carbon fiber cloth is pasted on the columns, beams and other parts of the building structure to improve the seismic performance of the structure through the high strength characteristics of carbon fiber cloth.

4, mesh shell reinforcement:

Lay steel mesh shell on the exterior or interior wall surface of the building, and then plaster, paint and other treatment.

Reticulated shell reinforcement can improve the overall strength and stiffness of a house, making it more earthquake-resistant.

5. Foundation reinforcement:

The bearing capacity and stability of building foundation are increased by concrete reinforcement and foundation treatment.

It can adopt reinforced concrete hanging raft, geoglage reinforcement and so on.

6. Masonry reinforcement:

Reinforce the walls of the house, such as thickening the walls, adding masonry, spraying fiber cloth and cement.

7, rubber damper reinforcement:

Rubber dampers are used in the building structure to absorb shock and adjust the stiffness and cycle of the structure to improve the seismic performance.

Iv. Acceptance after construction

After the reinforcement is completed, check and accept the reinforcement to ensure that the reinforcement meets the design requirements. The acceptance includes the appearance quality, dimensional deviation and strength of the reinforced parts.

5. Precautions

1, Follow the code: the house underpinning the foundation should strictly follow the relevant building codes and technical standards.

2, professional construction: the reinforcement project should be planned and supervised by professional architectural designers and engineers to ensure the reinforcement effect and construction quality.

3, security: the construction process should ensure the safety of personnel, take the necessary safety protection measures.

4, material quality: the reinforcement materials used should meet national industry standards to ensure the reinforcement effect.

To sum up, underpinning the foundation of a house is a systematic project that needs to consider multiple factors comprehensively and be carried out in accordance with professional procedures.
