The road surface shot blasting machine is an efficient tool for cleaning the road surface. It can quickly and effectively remove dirt, oil stains and snowflakes from the road. The use of road surface shot blasting machines can help keep roads clean and clean, and can significantly reduce the cost of road cleaning.

 

 

Working principle of road surface shot blasting:

 

The impeller driven by the shot blasting motor generates wind force and centrifugal force during high-speed rotation, and the amount of shot blasting up to 200kg/min enters the high-speed rotating sub-grinding wheel. Driven by the centrifugal force, the projectiles are directly thrown from the sub-grinding wheel into the directional sleeve, and then passed through The directional sleeve (controlling the foaming direction of the sand material) is thrown out, picked up by the high-speed rotating blade, and continuously accelerated and thrown along the length and direction of the blade. The thrown projectile will form a certain fan-shaped stream, which will be The speed of 120m/s is thrown onto the road surface or the surface of the steel plate. The depth is also determined according to the type of abrasive, which can reach 1-5mm. The unevenness is 100% uniform. The throwing will clean and strengthen the surface. Dust, impurities.

Asphalt road sealant of modified asphalt material

 Asphalt pavement cracks are a common disease on the road surface. If the cracks are not treated in time, the rainwater will enter the surface layer and the base layer through the cracks, and under the action of the traffic load, dynamic water will be formed to scour the structural layer, resulting in pumping or loose base layers. Such as water damage, resulting in cracks, potholes and other diseases on the road surface.

 

When cracks appear on the asphalt pavement, when they are first discovered, they should be dealt with in time to prevent problems before they happen. The use of asphalt road sealant to fill joints is an effective way to deal with cracks in asphalt pavement. It is recommended that road workers take measures as soon as possible. Next, we will introduce the joint filling characteristics of asphalt road sealant, performance characteristics of asphalt road sealant and construction attention points.

 

1. Filling characteristics of asphalt road sealant

 

After the cracks are slotted and before the joint glue is injected, the slot joints must be cleaned up to prevent the asphalt road sealant from being glued to the road surface and causing the glue to open or fall off. Use a high-pressure dust blower to remove the ash, Blow the soil to ensure that the asphalt road sealant is in full contact with the road surface and increase the adhesion, so that the filling effect is good, and it can be full, smooth, clean and beautiful.

 

The joint filling is basically not affected by the temperature during the construction period, and it can also be constructed at low temperature; the construction method is simple, easy to operate and master; the asphalt road sealant has better quality than hot asphalt filling joints, and has a long service life. Using this crack sealing machine and process for joint filling Once, the pavement can be maintained for more than two years without refilling. Compared with traditional hot asphalt manual filling once a year, the overall cost is reduced.

 

With better joint filling experience in future work, the use of asphalt road sealant to fill joints on asphalt concrete pavement has certain advantages not only in joint filling quality, service life, maintenance costs, etc., but also in daily highways. It has a good prospect of popularization and application in maintenance.

2. Material characteristics of asphalt road sealant

 

1) Water resistance. Asphalt road sealant itself is insoluble in water, does not absorb water, and can prevent water from penetrating from top to bottom;

 

2) Adhesiveness. Asphalt road sealant has strong adhesion to the road surface, and when the road surface is cold or thermally expanded, it can still be firmly bonded with it, and the adhesive surface will not be glued when it encounters water;

 

3) Elastoplasticity. Asphalt road sealant has good elasticity, and its stretching capacity meets the deformation requirements of cracks and joints, and can expand and contract with the pavement layer to ensure that it will not be broken;

 

4) High temperature stability. Asphalt road sealant will not flow due to heat in summer, pollute the road surface, affect the driving of vehicles, and can maintain a certain degree of toughness;

 

5) Low temperature flexibility. Asphalt road sealant does not harden or brittle at low temperature in winter, and maintains a certain degree of flexibility;

 

6) Anti-embedding. Asphalt road sealant can resist the embedding of sand and gravel debris under driving conditions, and ensure that the expansion and contraction of pavement joints is not hindered

 

7) Hot melt. Asphalt road sealant is a hot-melt material that can be heated repeatedly during use. The remaining materials in the joint filling equipment do not need to be cleaned, and can continue to be used after heating.

 

3. Points for attention in the construction of asphalt road sealant

 

1) Construction temperature

 

The construction temperature is one of the reasons for the peeling off of the sealant. If the road surface is wet and the temperature is lower than 4°C, the cohesive force of the asphalt road sealant will be reduced and it will fall off easily.

 

The overall temperature of the road surface is low. After the sealant is filled, the temperature drops rapidly, and the asphalt road sealant shrinks significantly. The temperature stress between the asphalt road sealant and the groove wall is relatively large, which will reduce the adhesion between the asphalt road sealant and the road surface. .

 

2) Crack humidity

 

The road surface should be dry when filling joints. If it is wet, the adhesion between the asphalt road sealant and the road surface will be reduced, causing part of the asphalt road sealant to fall off.

 

3) Keep it clean

 

Before filling the joints, use an air compressor to remove the dust and debris in the cracks after the slots and the loose objects around them to keep the cracks clean.

 

When cleaning cracks, in order to ensure that the asphalt road sealant and the crack wall are firmly bonded, the compressed air method and the wire brush method are often used to clean the cracks.

 

4) Filling range

 

If the rutting is serious, especially on the pavement with network cracks, it is not suitable to use this method to deal with cracks.

 

5) Filling material

 

The asphalt road sealant should have strong bonding ability with the seam wall, not stick to the wheel at high temperature, not brittle at low temperature, and have good durability.

 

6) Principles to be followed for joint filling

 

Asphalt pavement joint filling construction is to eliminate pavement diseases in the bud and achieve preventive maintenance. According to the long-term work experience, when using the joint filling machine to fill the joints on the asphalt pavement, the principle of filling the joints should be followed, so that every crack should not be missed to ensure the prevention of leakage.

 

When the crack width is more than 1cm, the effect of using asphalt road sealant is better, and when the crack width of asphalt pavement is less than 1cm, especially If the crack is less than 0.5cm, it is better to choose YG asphalt seam tape for seam treatment, because using YG asphalt seam tape for treatment will not cause artificial secondary damage to the asphalt pavement due to slotting, At the same time, it can also achieve the effect of partial micro-crack (healing).

What is concrete curb machine used for?

 Curb stone is a very important road facility, which refers to a stone object located on the edge of the road. The purpose of curbs is to separate roads and sidewalks and to protect structures, drainage systems and power lines below the road surface. In the process of urbanization, with the gradual improvement of traffic construction. The traditional way of operation and processing is realized through manual operation. Bricklayers invest a lot of personnel and have a heavy workload, and they also need to study the technical skills of the operators. Due to the technical level curve of personnel, the products produced are also good and bad, which is time-consuming and labor-intensive. Even the same personnel cannot guarantee that the quality of each processed product is qualified. The application of all synovial machines has gradually replaced manual processing.

What is a curb slipform machine?

 

 

The slipform curb machine is a machine and equipment used to build curbs and shoulders. It is often used in the construction of road curbs. The curb slipform machine can be used to lay curbs efficiently and standardizedly, and complete road construction and other work.

 

Prefabricated curb film machine, as the name implies, is a general term for the mechanical equipment used to construct automatic prefabricated film for curbs. Molding machine, prefabricated curb forming machine, etc. The core technology of this type of equipment is to add raw materials (cement concrete) into the hopper of the equipment, and then carry the corresponding mold according to the predetermined direction to achieve fast and high-quality sliding film operation .

 

Application advantages of curb slipform machine

 

Before the application of the curb slipform machine, the way of road curb construction was artificial prefabrication. The process of this method is relatively complicated. It is necessary to measure the construction mold first, and then carry out material preparation, mixing, mold loading, vibration, demoulding, etc. A series of work processes can prepare the curb stones, and after the curb stones are ready, they need to be installed. The whole process is complicated, lengthy, and consumes manpower and material resources.

 

The curb slipform machine automates this process, using machinery and equipment to complete the entire process of curb construction. There is no need to prefabricate the curb in advance. The machine goes through one molding process, which greatly saves labor costs, transportation costs, and consumable costs, and improves production. efficiency.

 

Working principle of curb slipform machine

 

The working principle of the curb slipform machine is not as complicated as imagined. The construction method is on-site pouring. After we set the relevant parameters of the equipment, the machine will continuously push the cement concrete into the mold and vibrate it through the motor of the equipment. , so that the concrete reaches a dense state, and then the curb slipform machine mold slides over the concrete road to form a strong and seamless curb. The machine equipment can repeat the action and complete the construction of the curb efficiently.
