Construction process: grassroots treatment → brush primer → grass-roots laying → surface layer laying
1.1 Primary treatment:
1.1.1 For poor flatness or too smooth ground surface Large-area site uses mechanical methods: use sandblasting or electric grinding machine to remove surface protrusions, loosen particles, break capillary pores, increase attachment area, vacuum cleaner to remove sand particles, impurities ,dust. For more depressions and potholes, apply plastic and quartz sand or fine rubber particles to mortar or putty repair.
1.1.2 If there is oil on the basic surface, it must be diluted with detergent and then cleaned. If a serious part needs to be eradicated and refilled.
1.2, the basic requirements for laying primer (a), construction temperature: surface temperature should be within 15-45 degrees.
(b) Concrete humidity (surface humidity): 5% or less As determined by the plastic film method, there is no water droplets under the film or the surface of the concrete becomes black. (c) Construction time: It is best to choose weather that is clear, fog-free, relatively low in relative humidity, and not exposed to sunlight.
1.3 Construction Steps (1). Inspect the foundation as required, handle the foundation and handle the retraction.
(2) According to the design requirements and the proportion of plastic used in the construction plan, configure a small amount of plastic and conduct a paving test to determine the construction plan and the treatment status of the inspection foundation.
(3) Measure parameters such as temperature and humidity and make records.
(4) Draw a construction line for each day's construction plan.
(5), deployment of plastic: According to the requirements of the binder and rubber particles in a prescribed ratio of mixing and stirring, adding the catalyst to continue stirring evenly. (6) Adjust the scale of the screeding equipment and screed the construction as required. At the same time, someone must be responsible for the use of a trowel, a trowel, or an oscillating trowel.
3.3 Test processing (1), using the taper cone to measure the thickness of the primer.
(2) Use a 3-meter ruler or a large scale to check the flatness of the primer. For the higher part, it must be polished as required.
(3) The black rubber particles exposed outside must be cut with a knife and tied.
(4) For indoor construction, it is necessary to wait until the primer has no smell before proceeding with the next construction.
1.4, laying surface
1.4.1, basic requirements: (same as primer)
1.4.2 Construction steps (a), inspection of primers and primer treatment as required.
(b) For indoor construction, it is necessary to wait until the primer has no smell before proceeding with the next construction.
(c) According to the design requirements and the proportion of plastics used in the construction plan, configure a small amount of plastic to conduct paving tests to determine the construction plan and the treatment status of the inspection foundation.
(d) Measure parameters such as temperature and humidity and make records.
(e) Draw a construction line for each day's construction plan.
(f) Blending plastics: According to the requirements, mix and stir the components A and B in a certain proportion, and then add the catalyst and surface layer PU particles to continue stirring.
(g) Using spray equipment, spray the particle mix onto the primer surface evenly.
(h) Adjust the spraying density of glue in time according to the spraying effect.
1.4.3 Inspection and treatment (a) Measure the total thickness of the plastic with a taper and a feeler gauge.
(b) Test the overall flatness with a 3 meter ruler or a large ruler.
Inspection and acceptance procedures Primary treatment → grass-roots brushing → grass-roots laying → surface layer laying.
Safe and civilized construction:
1. Warning signs and warning banners are set up at the construction site, and warning signs have dangerous descriptions and danger signs. The construction site was taken a pull warning to show the protection of bunting isolation barriers, and the foreigners were prevented from entering the construction site.
2. The distribution and installation shall be conducted with certificates, the circuit shall adopt the leakage protection circuit, and the floor cable shall be insulated waterproof cable. Machinery adopts "one machine, one brake and one control"
3, abide by the kindergarten management regulations. Obey the management of construction units and on-site management personnel.
4, abide by the acceptance procedure, scientific organization, scientific construction.
5. Educate employees on safety in production, strengthen the concept of the legal system, and raise awareness of employees and safe production ideology and self-protection. Self-study will abide by safety disciplines, safety production systems, and obey safety production management.
6, the construction site to do: work finished material net, site clear.
