? Abstract: The building foundation project is relatively hidden, and it is difficult to re-examine it after the project is completed. Its construction quality plays a decisive role in the quality of the whole building. Through the analysis of several common safety controls in building foundation construction, this paper puts forward several strategies for improving the safety management of building foundation construction.

As we all know, the building foundation is located at the bottom of the building and bears the whole weight of the whole building. If there are problems in the construction quality of the building foundation, the whole building will be in danger of collapse, which will seriously affect the normal life and personal and property safety of the people. Therefore, the construction quality of foundation engineering has become the most important thing to ensure the quality of the whole construction project, and it has been paid more and more attention by the majority of construction engineers. How to ensure the safety of building foundation construction has become one of the important topics discussed by practitioners in the construction industry. By analyzing several common safety control of building foundation construction, this paper puts forward several strategies to improve the safety management of building foundation construction, which can be discussed by people in the industry.

A, common building foundation construction safety control

1, pile foundation construction safety control. When hanging piles, the safety requirements for the vertical distance between piles and pile frames should be greater than 4m. When slowly hanging piles, manual control should be carried out in more than two different directions to ensure the stability of piles. When hanging piles, the hammer should be lifted to a certain position and fixed to prevent the hanging piles from falling. The lifting speed should be uniform, so that the pile can be lifted smoothly. When necessary, a wind power cable grid should be set up. The pile body needs to be cleaned, and the pile will interfere with the hoisting operation, so the pile operation should be stopped in time. Then, insert the pile, and it is absolutely forbidden to put hands and feet between the pile and the gantry. When piling, the pile cap and gasket must be suitable for the pile type and pile frame, and the damage should be repaired and replaced in time. Don't be eccentric with the hammer, and start to fall back slightly. When the strength suddenly increases, it is easy to cause the pile body to suddenly tilt, seriously damage the pile head and cause pile breakage. At this point, corresponding measures must be taken to continue the operation. When you pull out the pile, you should use force slowly. Observe the changes of pile frame and wire rope at any time to ensure the construction safety. 2. Safety control of strip foundation construction. After the foundation trench inspection is completed, the surface eluvial soil must be removed first to ensure that there is no water in the foundation trench. During the construction of foundation cushion, the horizontal elevation should be determined and the standard thickness should be controlled. When the concrete cushion is constructed in sections, it is necessary to avoid the phenomenon of slurry shortage and slurry shortage on the surface of the concrete cushion as far as possible to ensure the smoothness of the surface. Reinforcement plays an important role in construction, and related operations should be carried out in strict accordance with industry regulations, depending on the foundation height. When the height of the foundation is large, the reinforcement should extend to the bottom of the foundation to ensure the construction quality standard. For the construction of wooden formwork, wooden products should be used for certain reinforcement. Prevent heavy objects from crushing and ensure the firmness and durability of the template. Pouring concrete is the most important process. Before pouring, a layer of concrete with standard thickness should be paved, the thickness is generally between 5cm- 10cm, the position of steel dowel and steel bar should be fixed firmly, and then symmetrical pouring should be carried out. In the process of pouring, if walking or displacement is found, the operation should be stopped immediately and reinforced again. For the concrete that has been poured as required, it should be covered with water and kept at room temperature strictly. 3. Rational use of mechanical equipment. It can be said that the rational use of mechanical equipment can not only speed up the construction progress and ensure timely delivery, but also greatly improve the construction quality. The use of relevant mechanical equipment adapts to the working environment under socialized mass production, saves the construction cost, eliminates the potential safety hazards in the construction in the bud, and effectively guarantees the safety of foundation construction.

Second, improve the safety management strategy of building foundation construction

1, construction materials and equipment should be strictly controlled. The quality of building materials and equipment greatly affects the progress and quality of foundation engineering construction. Therefore, in the construction process, it is necessary to implement the quality responsibility system, strictly control the quality of related materials and equipment based on the principle of inspection before use, so as to move the pass forward, and put the responsibility to people and put it in place. 2, scientific arrangement of construction. Before construction, detailed construction plans and schemes should be made to achieve the most reasonable construction. Attention should be paid to coordinating the work equipment of each type of work, so that each type of work can cooperate and promote each other. It is necessary to strengthen the effective management of construction equipment, timely repair and maintenance, guide construction personnel to operate as required, and ensure the safety of equipment. In strict accordance with the standard proportion with the corresponding construction materials, accurate measurement, reasonable configuration. For materials with trial matching requirements such as concrete, trial matching must be carried out first to ensure accuracy before scientific construction. 3. Strengthen education and training. It is necessary to change the current situation of not paying attention to construction safety education and implement graded training, so that construction personnel can truly realize the importance and necessity of foundation construction and enhance their sense of responsibility and urgency. It is necessary to establish a corresponding access system, and carry out targeted education and guidance for construction personnel in line with the principle of "whoever trains is responsible", so that they can truly understand the skills of preventing construction safety risks, master more professional construction safety knowledge and corresponding safety laws and regulations, and improve their ability to resist safety risks. It is necessary to enrich the carrier, use modern education and training means such as multimedia, make safety education entertaining, let construction workers know safety knowledge vividly, learn the skills of self-protection and protection of others, and fundamentally put an end to safety accidents. 4. Establish an effective safety early warning mechanism. Before foundation construction, we should do a good job of investigation and research in the construction area. Especially in the excavation construction, it is necessary to remove obstacles on the ground and underground to ensure that the construction site is flat and free of water. In case of landslide or other unfavorable conditions, the construction plan should be adjusted in time. Operators of mechanical equipment under construction should have professional qualifications, and related electrical equipment should be maintained by special personnel. At the same time, it is necessary to build a dynamic security inspection system. Due to the different safety protection requirements in different stages of construction, it is necessary to define the safety measures in each stage of construction. It is necessary to implement dynamic safety protection, dynamically check the construction process, record it in time, track it all the way, and deal with it effectively to ensure safety.

Conclusion: In short, "the foundation is not firm, and the ground shakes." Today, with the rapid development of science and technology, the construction quality of foundation engineering is still an important topic of general concern to construction workers. Only by carrying out foundation construction in an organized, demanding and high-standard manner and strictly and orderly controlling the safety of building foundation construction can we truly ensure the quality and safety of the whole building, effectively prevent the collapse of the whole building and avoid heavy losses of people's lives and property.
