Curb sliding machine introduction
A curb sliding machine is a highly mechanized production equipment specifically designed for the manufacture of curb (a precast concrete member). It is mainly through the sliding form technology, in the construction site of the fresh concrete material continuous pouring and compaction molding, widely used in highways, urban roads, Bridges and other infrastructure construction fields. The following is a detailed introduction to the curb sliding machine:
First, the main features
High efficiency and stability:
The curb slip-forming machine has a high production efficiency, which can ensure the quality stability of the curb.
The construction progress is fast, the integrity is strong, the line is smooth and smooth, so that the appearance of the road is more beautiful.
High degree of mechanization:
The equipment has a high degree of mechanization, which can save manpower and labor costs, especially in large-scale projects, and the advantage of cost optimization is particularly prominent.
The operation speed is fast, and the mold can be matched according to the needs, which is suitable for many types of road shoulders, roadside stones and other facilities.
Easy to operate and flexible:
Curb sliding mould machine is easy to operate, small in appearance and convenient in operation.
It can be customized and purchased according to its own needs, for example, the walking speed of the machine can be stepless between 1-6m/min to adapt to different working conditions.
Versatility:
Curb sliding machine can be divided into extrusion type, hammer type, vibration type and vibration type according to different working principles.
It can be widely used in pavement paving, bicycle path, farm road, community road and other small roads, as well as the maintenance of grade highways.
Second, the working principle
Extrusion type:
The mixture is continuously pushed into the molding mold by the screw propeller, and is fully packed, and a certain extrusion pressure is generated inside the mixture, forming a curb with a certain density, strength and shape.
The horizontal reaction of the mixture to the screw conveyor is transmitted to the frame and the walking wheel, so that the whole machine moves forward along the road.
Ramming type:
A hammer head device is installed in front of the molding mold, and the hammer head makes reciprocating piston movement to push the cement concrete into the molding mold at a certain period and extrude the molding curb.
The movement of the machine depends on the reaction force of the movement of the ram.
Vibrating type:
A vibrating rod is added to the front of the forming die of the sliding mould machine, and the cement concrete can reach a certain densification through the action of the vibrating rod.
Vibrating type:
A high frequency and low amplitude vibrator is installed on the mold to make the cement concrete reach a certain degree of compactness.
The walking of the machine depends on its own power, rather than relying on the reaction force of the mixture on the machine, so the walking is more stable.
3. Scope of application
Curb slide molding machine is especially suitable for narrow areas and curved road paving construction operations, such as pavement, bicycle path, farm road, community road and other small roads pavement paving, as well as graded highway maintenance operations.
4. Construction cases
In practical applications, the curb slip-forming machine has demonstrated its excellent performance and wide application. For example, a company in the construction of the highway in Inner Mongolia using a multi-functional curb sliding machine, the machine eliminates the electronic sensor that is often damaged by the vibration of the machine itself, and improves the connection between the machine hopper and the template, which can not only be constructed on the base, but also can be laid on the asphalt concrete surface layer.
5. Economic and social benefits
Economic benefits:
The construction of curb slip-forming machine can improve the bonding degree between the curb and the lower bond layer and greatly increase the service life of the curb.
Strong integrity, reduce the ratio of damage to vehicles after collision, reduce maintenance costs.
It can be constructed first after the completion of the cement stabilized base, and then paved with asphalt concrete, avoiding the waste of asphalt concrete and reducing the cost of slotting.
Social benefits:
There is no joint in the construction of the curb, the line is smooth and smooth, and the color is consistent, which improves the overall beauty of the highway.
By improving the construction technology and mechanization level, the modernization process of infrastructure construction has been promoted.
In summary, curb sliding machine is an efficient, stable and flexible mechanized production equipment, which is widely used in the field of infrastructure construction such as highways and urban roads, and has made important contributions to improving the quality of infrastructure and construction efficiency.
