Construction management of double layer oil storage tank

1. Clear construction responsibilities
(1) The construction of double-layer oil storage tanks has strict technical requirements and requires on-site command and management. All departments should clarify their management responsibilities to ensure the smooth construction of double-layer oil storage tanks. For example, the construction unit should be responsible for the geological survey of the pressure vessel area, and arrange the survey data and related data to provide a reference for the design department to formulate the construction plan. In addition, site construction supervision must be done throughout the process to ensure personnel safety and project quality.

(2) The supervision unit shall supervise the design drawings and engineering progress of the oil tank from a professional perspective. In addition, the quality of the double-layer oil storage tank itself is also the object of key inspection by the supervision unit. The design unit shall compile construction plans and participate in investment estimates according to construction needs. Only by clear division of labor and fulfilling responsibilities, can the pressure vessel project be completed with high quality.

2. Management of construction technical points
(1) To implement the whole process management concept, management and control should be carried out in all aspects of oil tank reconstruction. For example, during the project preparation phase, the original single-layer oil storage tank at the gas station should be removed first. When removing the tank, clean the tank in advance, pay attention to cutting off the power supply and electrostatic grounding card, remove the tank protection or support equipment, and confirm that the tank is sealed and meets the requirements for removal before lifting the tank from the tank pit. When installing double-layer oil storage tanks, the relevant process pipelines must also be arranged. For example, the slope of the pipe trench should be controlled between 5% and 20%. After the double-layer composite pipeline enters the hole, the oil should be used for sealing. .

(2) In addition, such as oil tank outlet boxes, valves, quick connectors, etc., must also be installed in accordance with relevant technical standards. In the acceptance stage, it is necessary to ensure the completion of single-machine test and linkage test of mobile equipment such as fuel dispensers and submersible pumps; joint adjustment of the double-layer oil storage tank and double-layer composite pipeline leakage monitoring system; quality certification documents for oil tanks, double-layer pipelines and related structural parts Complete; pressure vessel anti-lightning, anti-static special acceptance is qualified with a test report; the local government competent department has completed various inspection procedures.

3. Construction progress management
(1) Strengthening schedule management can put gas stations into operation as soon as possible. In the integrated construction of anti-seepage integration, the following measures can be used to improve the management level of oil tank construction progress: compile a schedule and carry out work in strict accordance with the plan during the construction process, which can not only improve the utilization rate of resources, but also be able to complete the project within the scheduled construction period. Delivery works. Dynamic management is carried out, and project progress report meetings are held weekly and monthly to regulate and control the progress of reconstruction construction. (2) The schedule shall be jointly reviewed by the supervision unit and the construction unit, and implemented after review and approval. The adjustment of the schedule in the implementation must be based on the inspection results of the construction schedule. The construction unit shall strictly manage the construction unit in accordance with the nodes of the schedule, and timely request the construction unit to adjust the resource allocation according to the actual situation to ensure the realization of the project goals.

4. Construction safety management
(1) The integration of anti-seepage integration of gas stations has certain risks, and site safety management needs to be done well. The construction unit should combine the previous work experience to prepare materials such as the construction safety management system and emergency rescue plan in advance. First, it can provide guidance for safe construction on the site, and second, even if danger occurs during the reconstruction, emergency response can be done to avoid Expansion of security incidents. In addition, procedures and materials such as environmental safety protection must also be prepared in accordance with relevant regulations. It is necessary to ensure the safety of the construction personnel of the double-layer oil storage tank and also take into account the safety of the ecological environment.

(2) Do fire protection design for gas station reconstruction in accordance with relevant requirements, and submit the “Application Form for Fire Protection Design Review of Construction Projects” to the local fire department. Only after obtaining the “Planning Plant Construction Permit” can the pressure vessel area be rebuilt Construction.
