Are you still worried about not knowing how to do maintenance projects? Are you still worried about not knowing what equipment you need to do maintenance work? 2021 is an extraordinary year, do you want to be bullish in this year? First of all, let me popularize it for you first. What is a maintenance project? The maintenance project is also a highway maintenance project; that is, the maintenance and maintenance of highways. Maintenance focuses on the maintenance of the whole process starting from the completion and opening to traffic, and the maintenance focuses on repairing damaged parts. The equipment I'm mainly going to introduce to you is used to repair damaged parts. Whether it is cement or asphalt pavement, after being opened to traffic for a period of time, various damages, deformations, and other defects will occur one after another. These are collectively referred to as pavement diseases. Common diseases in the early stages are: cracks, potholes, ruts, looseness, subsidence, bridge culvert jumping, surface damage, etc. I would like to introduce you to solutions to crack diseases. For narrow and shallow cracks, we recommend that you use a seam tape. For wide and deep cracks, we recommend that you use a slotting machine, a filling machine, a hair dryer, and asphalt potting glue. Construction process: 1. For cracks less than 1 cm and deep, you need to use a grooving machine to open the crack wider first. 2. After opening the groove, there will be a lot of dust inside the crack. If you pour the asphalt filling glue directly into it, the glue cannot fit with the crack, so the effect of repairing the crack cannot be achieved. Therefore, you need to use a hair dryer to blow away the excess dust. If you buy a slotting vacuum all-in-one machine produced by Saao Machinery, this step can be omitted. The slotting vacuum all-in-one machine integrates slotting and vacuuming, and is in place in one step. 3. Inject the melted asphalt glue into the crack through the discharge pipe of the asphalt jointing machine. Saao asphalt filling machine is divided into many kinds, there are 60L asphalt jointing machine, 100L asphalt filling machine, 120L asphalt jointing machine, 200L asphalt filling machine, 350L asphalt filling machine, 500L asphalt filling machine, etc. The most commonly used in engineering are 60L asphalt jointing machine, 100L asphalt jointing machine and 120L asphalt jointing machine. 100L asphalt jointing machine parameters: model 0202SGF-10002020202020202 power source 02 imported generator heating source 0202 imported diesel burner 0202 control system 0202 whole process electronic constant temperature control filling speed 02020-25m/Min020202 heat conduction oil capacity 020245L filling material volume 0202100L0202 Applicable materials 02 Asphalt filling material, asphalt adhesive transition method 0202 self-propelled 0202020202 discharge pipe length 0202 standard 4.5 meters (optional 6 meters) Dimensions: 2150*1250*1410002mm According to your different projects, different equipment is equipped.
