Due to the limitation of construction technology, the road surface is uneven in many cases, and the vehicle cannot maintain a very good stability during driving, and it may cause ruts after repeated rolling, which is equivalent to being stuck in a car. vicious circle. Wouldn't it be better to use concrete laser leveling?
Pada masa kini, many roads are uneven, and there are many reasons. Now I will introduce the reasons for uneven roads:
1. The unevenness of the base layer affects the flatness of the road surface, resulting in uneven paving thickness, and the control of the base layer construction is not strict. Some even use bulldozers and graders to lay the base layer. The construction quality and flatness are difficult to control.
2. Pengaruh daripada jalan turapan jentera dan teknologi on the smoothness:
A. Improper selection of paver structure parameters, resulting in uneven paving thickness and waves;
B. Improper control of the base line of the paver, resulting in waves;
3. The influence of the quality of surface paving materials on the flatness:
4. Effect of rolling on flatness:
A. The use of low-frequency, high-amplitude road rollers will cause jumping and tamping phenomena, and excessive initial tonnage will cause pushing deformation;
B. Uneven rolling speed, sudden braking, sudden start, random parking and U-turn, parking on the rolled and formed road without turning off the vibration device will cause road congestion, and stopping on the uncooled road will cause sunken;
The laser transmitter used to control the ground level is arranged independently, and the level of the ground will not produce cumulative errors. Compared with the traditional method, the flatness of the super-large area is as easy to control, and at the same time, the construction joints and formwork usage of the floor are greatly reduced.
Fast construction speed: use laser leveling machine and other equipment to construct concrete slabs, which improves the work efficiency by 3 times and saves 30 percent compared with the traditional beam vibrator method. It can complete 2000 square meters per day on average. It is especially suitable for simple shapes and large-scale operations. pavement construction. High degree of automation and low labor intensity: the use of laser leveling machines and other equipment changes heavy manual labor into mechanical paving, vibrating, leveling, slurry extraction, and surface plastering, reducing the number of operators by 30 percent and reducing labor intensity at the same time. High economic benefit: the application of laser leveling machine and other equipment saves the cost by 2-3 yuan/㎡ compared with the traditional process, with fewer joints and lower maintenance costs in the later period, so that the economic benefit is significantly improved.
