With the continuous development of society and the steady growth of the national economy, people are paying more and more attention to the quality of life, which has led to an increased focus on building safety. In current construction and civil engineering projects, one of the common safety issues is the problem of cracks in buildings, which severely affects the overall safety of these structures and poses safety risks to people’s lives. To avoid this drawback and improve the safety of construction and civil engineering, construction companies have begun to use grouting technology during the building process, which is practical in application. 　　1 Practical applicability of grouting technology in the construction process of building and civil engineering projects. The use of grouting technology in actual construction is practically applicable; it ensures the safety of building construction and guarantees the quality and safety of buildings. A detailed analysis and explanation of the practical applicability of grouting technology are provided, which mainly include the following practical advantages. Firstly, in construction and civil engineering projects, grouting technology is employed in actual construction work. Its process is relatively simple, and the equipment used is easy to handle; it is convenient for use in practical operations as well as for transportation. In complex construction environments, it also possesses strong practical applicability. Secondly, during the construction of building and civil engineering projects, grouting technology can be utilized to address internal issues in buildings; it helps to optimize the relationship between concrete and the internal structure, increases the strength of the concrete, and ensures the integrity of the building’s internal structure. Thirdly, in actual construction processes, grouting technology makes use of reinforcing materials, which gives it good practicality and versatility; it has a high viscosity, a long service life, and has a minimal impact on the environment and nature. 　　2 The specific application of grouting technology in the construction process of building and civil engineering 2.1 Specific applications in the concrete construction process During the construction of buildings and civil engineering projects, grouting technology can be utilized during concrete construction, which helps ensure the integrity of the construction and prevents the occurrence of cracks. For concrete buildings, this primarily refers to the actual construction of the concrete structural elements, that is, the construction of the building’s beams, columns, slabs, and other structural components that bear weight. In construction projects, the beams and columns of a building are crucial for ensuring the safety and stability of the entire structure. Generally speaking, during building construction, traditional construction methods can lead to cracks in the buildings, which significantly affect the safety of these structures and pose a serious threat to those who live in them. Therefore, in the construction of building and civil engineering projects, using grouting technology in actual construction is practically applicable. In practical applications, it is mainly used for grouting during concrete construction, to ensure that the pore size remains between 0.7 and 1.5 mm. If the pore size is small during actual construction, it will reduce the efficiency and quality of the work. If the aperture is too large, it will reduce the stability of the building; therefore, it is essential to ensure that the size of the aperture is appropriate in order to enable efficient construction of civil engineering projects. Secondly, the spacing between holes should be maintained between 310 and 410 mm, and the depth of the holes should be designed based on the actual construction requirements. Meanwhile, epoxy adhesive can also be applied at the 29-meter mark where the crack occurs, which helps to prevent the leakage of grout during the actual implementation of the grouting technique and ensures its practical usability. 　　2.2 Specific applications during basement construction In civil engineering construction, leakage problems often occur during the construction of building basements, which severely affects the safety of those basements. The leakage problems in basements mainly fall into two categories: leaks at expansion joints and leaks in the exterior walls. Analysis and research on the issues related to the exterior walls of basements have revealed that they are primarily caused by problems inherent in the building itself, including issues with the composition of the concrete, mistakes during secondary vibration processes, and excessive thickness of the water-facing layer of the exterior walls. The occurrence of cracks in these walls is mainly due to the fact that the wall panels were not properly protected after construction, allowing them to be exposed to rainwater and thus leading to leakage problems. Leakage problems have arisen due to the failure to carry out secondary waterproofing work in the basement in a timely manner, as well as the lack of timely removal of debris from the joint strips. In the face of this situation, it is necessary to apply grouting technology during building construction, in accordance with certain construction requirements and specific procedures, in order to prevent leaks in basements and ensure the efficient progress of civil engineering projects. 　　2.3 Specific applications in the wall section In the field of building and civil engineering, the main causes of cracks in walls are human factors; improper handling by workers, as well as effects of temperature, lead to the occurrence of such cracks. The causes of cracks in wall panels are similar to those of cracks in walls. Generally speaking, the degree of cracking in walls is greater than that in wall panels. Furthermore, during the actual construction process, it is necessary to pay more attention to the building walls. Good-quality materials should be used to ensure that they possess adequate shear strength. In areas where cracks frequently occur, drilling operations should be carried out around those areas to enhance the stability of their base. When carrying out grouting work on the exterior walls, small holes can be created in those walls to increase their density, thereby ensuring better waterproofing and safeguarding the safety and stability of the building. 　　3 Conclusions Grouting technology is practically applicable in the construction of building and civil engineering projects. Its technique is relatively simple, and the equipment used in practice is convenient, making it easy to use and carry. In practical applications, grouting technology has a wide range of impacts: it helps to prevent the occurrence of cracks in buildings, ensures the integrity of building complexes, reduces costs in terms of labor and resources, possesses strong reinforcement capabilities, and helps to ensure the safety of civil engineering construction, thereby enabling construction work to proceed effectively. 　　References:
