【正文】 e of the best. Sliding mode on the paver, the concrete is vibrated by the vibration program vibration bar, and then vibrated by the vibrating beam. Vibrator in the equidistant uniform width paver layout, and its amplitude, frequency and power are adjustable to overe the shortings of artificial uneven paving. Therefore, the concrete slab paving uniform, dense, no weak points, or weak side. Strong construction management to ensure that concrete quality Strengthen the construction management is to ensure that the quality of the concrete one of the important ways. First of all, the quality control of raw materials. A variety of technical indicators of the raw materials must meet the design and the relevant regulatory requirements. Materials do not fail. Followed by the construction of concrete mixing mix control, a variety of materials measurement must be accurate. Finally, there is fresh concrete to control the machine from one mode to the period of not more than the initial setting time of cement。 At the same time to prevent concrete segregation. 4 To deal with cracks Vertical cracks in cement concrete pavement may be the deal with all of local processing and handling methods. Before processing, the cracks must be generated to investigate the cause analysis, to determine what causes and then determine what approach to use. All processing This approach is to crack the concrete slab has been cleared of all to retain the horizontal connecting bars. If there is damage to the grassroots level appropriate to deal with, and then repoured with the original surface of the concrete slab, such as strength. If that is the basis of cracking due to the road surface caused by cracking, it should be in the new fullcast concrete slab added to a wide range of singlelayer or doublereinforced, reinforced the general specifications of the steel used Φ10 made to 20 * 20cm spacing . This method is suitable for a variety of reasons arising from the road surface cracking. The use of this approach, the cost of the larger. Partial treatment Local processing is in the cracks on both sides of the range of not less than 50cm cutting a groove, deep groove thickness of ~ times the slot on both sides must be neat, should be cut cutting machine. Clean bottom, laying in the bottom Φ10mm reinforced with banding of 10 * 10cm steel net, and then poured with the same intensity of the original concrete pavement pebbles concrete, moisture transport and opening up health after 28 days. This method is relatively simple to deal with the economy, but only applies to the road as a result of their own strength and have a crack.
