There are a wide variety of concrete transportation tools and different transportation methods. It is better to use high efficiency and low transfer times to determine the transportation method. Commonly used transport equipment include single wheel carts, two-wheel rack trucks, dump trucks, automobiles, belt conveyors, tower cranes, gantry cranes (with buckets) and pumped concrete. Commodity concrete production, from the mixing station to the pouring site, is transported using special concrete mixer trucks. Concrete transport is mainly based on concrete mixer trucks. This vehicle belongs to large-scale industrial vehicles. What do you need to pay attention to when driving safely? First of all, before starting, pay attention to: 1. Check whether the appearance of the organization scratches, check the hydraulic pump, the hydraulic motor should be no oil and other undesirable phenomena. 2, check the power take-off device - PTO situation, there is no loose screws and bearing oil leakage and other phenomena. 3, check the gearbox, engine oil, power steering fluid, battery fluid is enough, in line with the requirements of manufacturers. 4. Check whether the safety devices are effective and have no aging. 5, check the tubing, air pipe leakage aging phenomenon. 6, check the tire pressure is standard. During operation, it should be noted that 1, after the engine is started, the engine is idle for 5-10 minutes or more. 2. Rotate the drum at low speed for a few minutes. The oil pump and drum should be normal. 3. When the vehicle is stopped and cleaned, pay attention to the drum driving position and other rotating parts. 4. If the driver leaves the cab due to material preparation or discharge, the vehicle should be fully braked. 5. Be careful when operating the lever and avoid rough operation. 6. Prohibit rapid shifting, hurry up, and stop suddenly. 7, concrete feed, stirring, discharge should follow the operating procedures. 8, before walking, check the water tank. 9, downhill on the road to pay attention to the situation. Things to note when parking are: 1. After the work is completed, thoroughly clean the machine, ensure that there is water in the tank before cleaning, and do not turn the pump under the condition of sewage. 2, thoroughly remove the drum inside and outside the concrete. 3. Add grease and engine oil to the joint according to the lubrication map. 4, check the drum blade wear. 5 Clean all the water after cleaning. The concrete transport vehicle has made great contributions to the construction of our country's building area and the building of various buildings, and has promoted the development of the concrete transportation industry. The price of concrete trucks varies from tens to hundreds of thousands, depending on the loading capacity. Of course, there is also a special concrete truck rental company. If you rent a car, it is much cheaper and it is also very convenient. With the constant innovation of technology, the concrete transporter is developing in a simpler, more compact and lighter direction, enhancing safety.
Classfication for the sound barrier wall: Base on the application environment: the traffic noise barriers, equipment noise attenuation noise barriers, factory noise barriers; Base on the material: metal noise barriers,concrete noise barriers, PC noise barriers,etc; Base on different application: rail noise barriers, highway noise barriers,urban landscope noise barriers,redetial area noise reduction noise barriers.
Structure of the sound barrier: Sound barriers are made of the steel H beam and Sound Absorbing Panels. Steel H beam is the main force components, it si fixed by bolts or welding on the road barrier wall or the side of the embeded steel plate. Sound absorbing panel are the main noise reduction component,it is ixed by high stength spring clip on the groove of the beam. Considering the environment the highway, railway road and subway, it is designed for open-air corrosion, easy transportation and installation, and long life.
Height of the sound barriers is also bettween 1m-5m. Covering the effective area, the noise reduction is 10-15dB(A)(125HZ-40000HZ,1/3 octave),up to 20dB(A).Generally the sound barriers height and distance is more bigger, the reduction effect is more better.
1. Good perfomance of acoustic insulation: the average acoustic insulation amound should not less than 35dB;
2. High sound absorption coeficient: the average sound absorption coeficient amount should not be less than 0.84.
The metal Sound Barrier Wall accoding to diffirent hole shape,there also are two types:
1.Window-blinds Types
2.Round shape types
