4. Construction units and supervision units that have been determined to meet the qualification requirements must have qualification certificates that match the project scale, and project managers and technical personnel must hold certificates; supervision units must have corresponding supervision qualifications and dispatch professional supervision personnel. Qualification review can ensure that construction and supervision capabilities meet project requirements and ensure quality and safety.

5. Examination content: construction engineering quality acceptance specifications, quality common fault prevention and control, quality inspection technology, data collation, theoretical examination. Requirements for application for safety officer (C certificate, intermediate level): junior college degree or above, no working years required, you can apply for the application after graduation (some provinces require enterprises to be on the job, and you can apply for registration).

Key points of construction quality management for assembled integral concrete structure projects

1. Quality acceptance and monitoring acceptance content: component appearance quality, size deviation, position of embedded parts, and tightness of connection nodes (such as grouting material strength testing). Monitoring focus: During the construction stage, it is necessary to monitor the verticality, horizontal displacement and stress changes of components to ensure structural safety. Implementation steps of PC frame system (assembled integral concrete frame) Structural selection during the design stage: Select the post-pouring or joint prefabrication scheme of frame nodes according to building functions and seismic requirements.

2. Use a slurry replenishment observation tube to prevent slurry backflow. Keep the grouting material stable to ensure that the grouting is full and free from voids. Summarize the construction technology and quality control measures of sleeve grouting material for prefabricated concrete structures are crucial to ensuring project quality. Through strict construction preparation, process flow management and quality control measures, the standardization and accuracy of grouting material preparation and grouting operations can be ensured, thereby improving the overall quality and stability of prefabricated concrete structures.

3. It has an important impact on the overall project construction quality. Therefore, it is crucial to master the construction technology and quality control measures of sleeve grouting materials for prefabricated concrete structures. The sleeve grouting construction technology of prefabricated reinforced concrete structures should pay close attention to technical preparations for construction preparations: clarify the technical parameters of sleeve grouting, conduct process testing and feasibility analysis, formulate construction plans and design drawings disclosure, clarify quality control points, and keep written disclosure documents.

4. Relevant government supervision agencies: Supervision agencies at all levels shall, in accordance with the requirements of the "Work Manual for Quality and Safety Supervision of Shanghai City Construction Projects" and effectively carry out supervision work based on the particularity of the construction of assembled integrated concrete structures, focusing on spot inspection plan approval, on-site safety protection, shift leadership by the person in charge and the certification of the operators to ensure the implementation of quality and safety responsibilities.

5. Preface In the construction of prefabricated building projects, the vertical prestressed connection mainly uses sleeve grouting technology. This is the core technology recommended according to the "Technical Regulations for Prefabricated Concrete Structures"(IGI1-2014) and is important for improving the overall project construction quality.

6. Preface In the construction of prefabricated building projects, the sleeve grouting method is often used for vertical prestressed connections, which is proposed in accordance with the "Technical Specifications for Prefabricated Concrete Structures"(JGJ1-2014). Grouting sleeve is the core technology and has an important impact on improving the overall project quality.

Are grouting workers a special type of work?

1. Some of the grouting workers belong to special types of work. The specific analysis is as follows: High-pressure grouting operators clearly belong to special operations. High-pressure grouting operations involve operations in high-pressure environments and impose high safety technical requirements on operators. Once improper operation, serious safety accidents may be caused, causing harm to the operators themselves, the surrounding environment and personnel.

2. The overall situation is characterized by "more work, more gain", but its long-term stability is poor and it may face unemployment risks when there is no project. Working environment and risks: Grouting workers with high risk and easy to cause occupational diseases are classified as special types of work. There are multiple dangers in the working environment: Physical hazards: During tunnel grouting, the temperature inside the tunnel exceeds 50 ° C, which is prone to heat stroke; coal mines and other places are seriously polluted by dust and long-term exposure may cause pneumoconiosis; there are risks such as falling and squeezing during aerial work or mechanical operation.

3. Special types of work refer to factors that harm the health of employees in terms of labor intensity, labor conditions and on-site environment during the production process of the enterprise. Work types within the scope of the catalog of special types approved by the former personnel and labor administrative departments of the State Council and the competent departments of various industries. Including high-altitude and particularly heavy manual labor positions, underground, high (low) temperature jobs and other jobs that are toxic and harmful to health, as well as jobs that work in high mountains and plateau areas above 3500 meters all year round.

What is the certificate of grouting workers

1. Workers who use grouting and grouting usually need to hold a construction committee technician's grouting certificate or grouting worker's employment certificate. Construction Committee technician grouting certificate: Issuing institution: This certificate is issued by the housing and urban and rural construction department. Nature of certificate: It is a national vocational qualification certificate specifically for skilled personnel engaged in building grouting construction. Purpose and significance: The purpose is to prove that the holder has the professional skills and knowledge required to engage in grouting construction, and has corresponding professional abilities and qualifications.

2. The certificate is divided into three levels: primary, intermediate and advanced. The assessment content covers the entire process of component deepening design, production, construction and installation. The examination adopts a combination of theoretical computer examination and practical assessment. The practical part requires candidates to complete key processes such as component hoisting, grouting connection, and waterproofing treatment, focusing on the hands-on ability and standardized execution ability.

3. Applying for grouting certificates or grouting certificates usually involves relevant vocational skills training and assessment.

4. The construction team must have professional contracting qualifications for special engineering (structural reinforcement), and technical personnel must have certificates (such as welder and grouper operation certificates).
