Discussion on Safety Management and Equipment Allocation in Mechanical Construction

With the rapid development of my country's construction industry, especially the continuous increase in urban residential areas, mechanized construction is playing an increasingly important role in engineering construction. However, along with the development of engineering construction, the contradiction between speed, quality, and efficiency is becoming increasingly prominent, which poses new requirements for engineering construction. Specifically, it requires solving the problem of carrying out engineering construction quickly, efficiently, and with high quality. Traditional manual labor and simple mechanical construction methods are no longer suitable for the requirements of engineering construction; for modern building construction, only mechanized operations can be adopted. Therefore, the safety management, selection, and configuration of construction machinery are extremely important and urgent.

1. Analysis of the causes and countermeasures for safety management problems of construction machinery and equipment
Construction machinery safety is a science that primarily studies the potential harm to operators caused by construction machinery under certain conditions during operation, assembly, disassembly, debugging, and transportation, as well as the corresponding protective measures. Construction machinery safety is crucial to the personal safety of construction workers and the property safety of enterprises, and is an important component of sustainable development. Although the overall accident rate of construction machinery in my country has shown a downward trend in recent years, the situation remains serious, and many problems still exist. Therefore, how to scientifically implement and strengthen the safety management of construction machinery is a problem we currently face.
1.1 Analysis of the Causes of Safety Management Problems in Construction Machinery and Equipment With the development of the construction industry, the use of various types of construction machinery is increasing, and safety issues are becoming more and more prominent. These safety problems are mainly caused by the following reasons:
(1) The legal system for safety management is incomplete.
(2) Failure to strictly implement national and industry normative documents.
(3) Safety supervision is subject to multiple management bodies.
(4) Poor management of construction machinery operators.
(5) The technical files of construction machinery are incomplete.
(6) Poor management of construction site for mechanical equipment.
(7) The construction environment for mechanical equipment is harsh.
1.2 Reform Strategies for Construction Machinery Safety Management
1.2.1 Improve the legal system for safety regulations
Improve safety laws, regulations, and rules. Based on the current state and existing problems of my country's safety legal system, the following aspects should be addressed: 1) Accelerate safety management legislation. 2) Formulate supporting regulations. 3) Implement a mandatory scrapping system for machinery.
1.2.2 The authority of safety supervision departments shall be strictly defined in accordance with the law.
Departmental authority should be strictly defined according to law, and industry regulatory responsibilities should be strengthened. Laws and regulations necessary for law enforcement should be formulated promptly, and conflicting legal provisions between departments should be thoroughly reviewed. Each department in the state has a clear division of responsibilities; only when each department performs its duties can the healthy operation of society be guaranteed. Construction administrative departments at all levels bear the responsibility of routine supervision and inspection of work safety, occupying a core position and playing an extremely important role in the supervision of construction project safety. Overlapping departmental regulations inevitably lead to confusion in law enforcement. Relevant departments should fully recognize the harmfulness of this problem and organize personnel to review existing laws and regulations as soon as possible to ensure the dignity and authority of laws and regulations.
1.2.3 Strictly implement standards and establish on-site rules and regulations.
All machinery and equipment used on construction sites must strictly comply with current relevant standards and specifications. Effective on-site management systems should be established, including: 1) Each party involved in the construction site should assign dedicated (part-time) machinery and equipment management personnel responsible for the safe management of machinery and equipment use. 2) Corresponding safety management regulations for machinery and equipment should be established on the construction site (safety management responsibilities, safety technical briefings, shift handover, maintenance, inspection, and document management, etc.). 3) Major machinery and equipment should be subject to a "three-fixed" system: fixed machine, fixed personnel, and fixed job responsibilities. 4) Machinery, electrical equipment, and construction tools must not be operated while malfunctioning. 5) Machinery and equipment on the construction site must be used correctly and operated safely; overloading and assembling equipment are strictly prohibited.
1.2.4 Improve technical documentation
Dynamically tracking and collecting safety management technical data on various types of construction machinery entering and leaving the site according to the construction progress, this allows for the timely establishment of relevant safety management technical files for construction machinery. These files clearly reflect the status of construction machinery during construction, facilitating various safety inspections and ensuring the implementation of safety responsibilities. This is an effective measure to concretely implement the "Safety Production Law of the People's Republic of China"; it meets the requirements for construction safety management files during the completion and acceptance of construction projects and conforms to the principles of establishing technical files. 2. Research on the Allocation of Construction Machinery

Mechanized construction is a comprehensive operational process and management system involving interconnected mechanical systems. Its goal is to achieve the best economic and technical results for the entire system. To achieve mechanized construction, it is essential to address the rational allocation of construction machinery based on the characteristics of various projects and the specific requirements of the construction content. This includes meeting the most basic requirements of the construction project regarding tasks, quality, and schedule, ensuring all strength indicators of the project are met, and improving the coordination of the construction machinery fleet. The aim is to improve the utilization of machinery and the quality and efficiency of construction tasks, while simultaneously increasing project benefits and reducing machinery costs. Furthermore, it is crucial to enhance the systematic nature of the machinery, ensuring that its performance and production capacity adapt to the specific requirements of construction, and minimizing equipment investment.
2.1 Principles for the Allocation of Construction Machinery and Equipment
1) The allocation of mechanical equipment must be consistent with the construction organization; 2) The allocation of mechanical equipment must be conducive to construction, to improving the utilization rate and integrity rate of machinery, to improving the level of mechanized construction, and to improving economic benefits; 3) The configuration of mechanical equipment must adapt to the changing characteristics of construction projects and have a certain adaptability; 4) The allocation of mechanical equipment should conform to the principle of combining centralized and decentralized approaches.
2.2 Simplification requirements that must be met for mechanical components
1) The technical specifications of each machine must meet the technical standards of the established project; 2) Where the process allows, heavy machinery should be used as much as possible and sufficient workload should be arranged for it; 3) The machinery must have good performance; 4) The machinery must have good reliability.
2.3 Methods for allocating construction machinery
The general process of allocating construction machinery involves: analyzing the problem, defining objectives, formulating and analyzing solutions, selecting solutions, and implementing solutions. When selecting a solution, the following four aspects should be considered through analysis of factors influencing the allocation of construction machinery: the quality indicators of the machinery; the adaptability of the allocation solution to the construction task; the economy of the allocation solution; and the coordination between the construction machinery. These comprehensive indicators include both quantitative and qualitative factors. Even the quantitative factors vary significantly under different management levels and usage conditions, requiring determination based on specific circumstances. Furthermore, these factors often influence each other, and their correlation can be considered fuzzy, even if accurately determined. Therefore, using fuzzy comprehensive evaluation to solve the problem of allocating construction machinery is both suitable for the actual situation of construction machinery and highly feasible.

3. Conclusion

The rational selection and configuration of construction machinery, along with scientific safety management, are crucial guarantees for achieving mechanized construction. Scientific and advanced machinery allocation and management not only improve machinery utilization and maximize its efficiency, but also ensure project quality and timely completion of tasks, generating significant social and economic benefits.
