Before the membrane structure construction, make sufficient preparations, the implementation work can be carried out in a systematic way. At the same time, when we make good preparations, the quality of the project, the timely delivery of the project is also a guarantee. So what are the preparations for membrane structure construction? Here small make up to explain to you!
1. According to the requirements of the construction and transportation of the project, prepare the operation instruction or process card of each procedure respectively according to the general planning of the two parts of prefabrication and on-site installation in the factory.
2. Five days before the construction, relevant departments should be organized to carry out comprehensive maintenance of all kinds of machinery and equipment to be used in the construction, so as to avoid mechanical failure in the construction process, affecting the construction.
3. According to the requirements of construction organization and design, complete all kinds of materials, appliances and hoisting ropes needed for construction, and pull and hold cable wind rope, etc.
4. Welding process evaluation: Butt weld and fillet weld process evaluation.
5. welders and other types of work for pre-job training, and qualified after examination with a certificate.
6. Check, maintain and submit all measuring instruments and equipment for inspection.
7. Before the start of the installation project, organize surveyors to review the deviation of the vertical and horizontal axis lines and the elevation of the embedded parts, carefully record the review data of each line column, and copy the relevant data to the project department head, technical director, construction personnel and construction team. Each construction team in the construction, this data as the component installation adjustment, the basis for finding the correct. At the same time, the surveyors are organized to return the contact points of the main arch and the secondary arch to the ground, and make measurement marks on each return point.
8. After the finished components are transported to the site, the technical responsible person shall organize full-time personnel to carefully review the components or semi-finished products (review the geometric dimensions of the components or semi-finished products, appearance quality of the welding seams, component qualification certificate and flaw detection inspection record of the welding seams, etc.), and make careful records of the review data. When the component or semi-finished product is transferred to the next process, the inspection record shall be transferred together with the component or semi-finished product handover list to the person in charge of the construction of the next process.
9. In construction personnel before entering the construction site, the project department should focus on the main technical characteristics of the project, the construction of organization construction personnel to each job technical clarificaiton, to make all kinds of construction personnel on its to use of the construction can skillfully master the machine operation and performance, so that in the construction of the skilful operation of a respective construction machines and tools.
10. All construction machinery and personnel shall enter the site.
11. Temporary facilities: site office and living facilities, material warehouse, tool warehouse, shed, etc.
12. Temporary water supply and power supply: Temporary water supply and power supply shall be provided by the owner. Separate water meter and power distribution box meter shall be installed by us.
13. Temporary road: Use the owner's temporary road to enter the material and clean up the site. Dormitory, temporary material warehouse and tool warehouse are determined according to the construction site.
