The following is a list of topics related to the interpretation of the foundation grouting reinforcement construction specifications, and those who want to know may wish to take a look.
Interpretation of the "Ground Grouting Reinforcement Construction Code" is a technical document for the standardization of foundation grouting and reinforcement projects, the main purpose of which is to ensure the safety and quality of the construction process.
1. Related features:
1. Possession and operability: The specification is verified by experts and practice, and has certain operability.
2.Comprehensive: The specification stipulates many aspects such as the preliminary preparation of foundation construction, the selection of equipment and materials, the construction technology, the construction steps and the acceptance.
3.Phased and process-oriented: the specifications specify the various stages of the foundation grouting and reinforcement project and the corresponding construction process, so that the construction process is carried out in an orderly manner and has a certain process.
4.Emphasis on quality control and safety assurance: The specification has clear requirements for the quality requirements of grouting materials, construction process control, construction process monitoring and equipment safety to ensure project quality and construction safety.
Second, the process flow:
1. Preliminary preparation: including surveying the construction site, determining the construction plan, preparing relevant materials, ensuring the quality and quantity of equipment and materials, and formulating the construction plan.
2.Construction preparation: including the preparation of personnel and equipment, the setting of construction signs, the layout of construction routes, etc.
3.Construction technology: mainly includes pretreatment, installation and commissioning of grouting equipment, implementation of grouting process, post-grouting treatment, etc.
4.Construction control and monitoring: monitor and control the grouting pressure, flow, grouting speed, grouting time, etc. in the construction process.
5.Construction end: After the construction is completed, the ground is cleaned up, the equipment is dismantled, and the acceptance and measurement of the steel pile, the construction process record and design drawings are made.
3. Acceptance criteria:
1. Grouting strength: check whether the grouting strength meets the requirements by collecting samples for testing.
2.Grouting perfusion: Judge the perfusion degree of grouting by checking the filling of the grouting in the hole.
3.Grouting thickness: Check whether the thickness of the grouting layer meets the requirements of the specification.
4.Grouting quality: The grouting should be uniform and tight, and there should be no agglomeration and no pipeline blockage.
5.End treatment: check the treatment of the grouting end to ensure the overall effect of the project.
Interpretation of the construction specification for foundation grouting reinforcement has and operability, emphasizes quality control and safety assurance, and has clear provisions in terms of process flow and acceptance. Therefore, the rational use of this specification can improve the quality and construction safety of foundation grouting reinforcement engineering.
