Where are impact rollers used? What is an impact roller

What is an impact rollerWhat do you say about the technical specifications for impact rolling?

What is an impact roller? The national technical specification for impact rolling "Technical Guidelines for the Application of Highway Impact Rolling" defines the term impact roller as: "The non-circular shape of the roller (generally composed of curves as sides.

Three, four, five-sided regular polygon) compaction wheel rolls under the action of traction and self-driving force, and the construction machinery and equipment that carry out periodic impact rolling on the rolling surface. ”

The English name of impact roller is: impact roller, because of the special shape of the "non-round" roller, it has obtained many names with shape characteristics, such as: triangle roller, quadrangular rammer, plum roller, triangular roller, plum roller and so on different names or names.

"Impact" is "tamping", the corner difference brought by the non-circular rolling wheel of the impact roller, so that it has the "rolling" characteristics of "rolling (roller)" in the process of rolling construction, and at the same time has the "tamping" characteristics of "tamping", therefore, some people also call the impact roller impact roller, impact rammer, tamping machine, etc.

The compaction force of the impact roller is as high as hundreds of tons, the effective impact depth of compaction is about 2 meters, and the impact depth is as high as 5 meters.

The process or method of using impact roller to compaction the rolling surface is called impact roller compaction, and the impact rolling effect of the impact roller is related to factors such as soil conditions, the size of the impact roller model and the impact rolling speed.

What is a plum mill impact roller, do you understand?

Impact roller, alias impact roller, impact roller, plum blossom roller and other different names impact roller is actually a new type of towing roller, its rolling impact wheel is a polygonal non-circular cam, through the tire tractor traction operation, therefore, the impact roller is composed of two major components: tractor and impact wheel. The impact wheel is usually composed of a variety of 3 5 side non-circular equilateral tugboats, and the purpose of compacting the road surface and roadbed is achieved by continuous rolling impact, because it has no power itself, the impact wheel needs to be driven by large traction equipment to work. The tractor is a special large-scale engineering traction machinery in the whole set of impact roller equipment, and is an important part of the whole set of impact compactor, which can be replaced by traction machinery such as large tractors, loaders, and automobiles in engineering practice.

The impact roller drives the non-circular impact wheel through the traction of the tractor, and uses the weight of the impact wheel itself and the impact force when moving forward to crush and compact the cement pavement and roadbed.

The main function of impact rollers is to compact the foundation.

Impact rollers can also be used to crush old pavement.

Hello, the role of impact rollers is mainly reflected in compaction, and impact rollers are required in the following situations:

1. The compaction of loose soil, depending on the type of soil and water content, the compaction thickness can reach 5 meters, and the compaction capacity can reach 2000 cubic meters per hour.

Second, the completion of the soil foundation to increase the degree of compaction, reduce the subgrade settlement deformation, improve the overall strength of the subgrade and construction quality.

3. The cement concrete pavement is cracked in front of the asphalt cover (micro-cracks from the pavement to the bottom of the cement slab) to prevent reflection cracks.

Fourth, the cement road and semi-rigid base with structural problems are crushed and compacted, and the diseases of soil foundation and base and semi-rigid base are treated. This method also saves the cost of labor and disposal of old cement plates, solves the problem of discarding old cement plates, and meets the requirements of saving and environmental protection.

Thank you!

Impact roller, also known as impact compactor and impact roller, is a new type of towed roller belonging to the roller.

The impact roller is pulled by the loader, drives an impact wheel, and uses the weight of the impact wheel itself and the impact force when advancing to crush and compact the cement pavement and roadbed.

The impact compactor was proposed by the South African company Aubrey Berrange in the 50s of the 20th century, and became a mature non-circular rolling compacting machine for practical use in the 70s and 80s of the 20th century, and began to be promoted to the world in the 90s of the last century.

Here's how the encyclopedia describes impact rollers:

Impact roller, also known as impact roller, impact compactor, impact roller, is a new type of towed roller belonging to the roller. The impact roller drives a single or a pair of impact wheels through the traction of tractors, bulldozers, loaders and other traction machinery, and uses the weight of the impact wheels themselves and the impact force when moving forward to crush and compact the cement pavement and roadbed.

The GB T 25626-2010 national standard for impact rollers was first released on December 1, 2010 and was implemented on March 1, 2011. The second edition began in 2019 and the new version was implemented on April 1, 2019. ”

The impact roller is the impact roller, also known as the impact compactor, which is the special construction machinery and equipment used in the impact rolling construction process, which belongs to the road roller.

Impact rollers.

The impact roller is usually composed of 3 5 non-circular equilateral rollers, because it does not have power, it needs to be driven by traction machinery such as impact roller tractors or large tractors for rolling construction.

The impact roller consists of two parts, a tractor and a compaction device, which are connected by a buffer frame connection assembly. The tractor is divided into front and rear frames, and the middle is connected with a steering twist as the slewing center of the steering mechanism of the hydraulic cylinder. The front frame houses components such as the engine, hydraulic transmission, front axle and cab.

Impact compaction technology has been widely used in the country, but due to the different soil quality, stamping roller model, application conditions, etc., its compaction effect, construction technology, and quality control are also different, so it is necessary to build a test section before construction to determine the appropriate construction technology and quality control standards. In the early days, impact rollers were mainly used in airports or high-level highways or railways, and it is not difficult to see that the rolling effect of impact rollers is superior to that of ordinary vibratory rollers.

Impact rollers are construction machinery and equipment, mainly used for foundation compaction and road surface crushing. The impact roller is a new type of tow roller that is different from the cylindrical rollers of conventional rollers.

Impact rollers are construction machinery compaction equipment.

The impact roller is a towing roller with a 3 5 side regular polygon, because it does not have power, it needs to roll under the drive of traction machinery such as impact roller tractor or large tractor.

<> in the construction of the project, often use the impact roller to detect the road section, the industry is called "detection enhancement of the pressure", the detection of the enhanced pressure can find whether the subgrade compaction effect is up to standard, enhance the pressure effect so that the construction of the subgrade is covered, 100% detection, at the same time can find the defects, eliminate the defect in advance, by virtue of the amount of settlement obtained to intuitively detect the compaction quality of the subgrade, and in this detection to make it reinforced.

It is the impact roller impact rolling foundation in the picture below.

Impact roller, also known as impact roller, impact roller, impact roller, is a new type of towed roller belonging to the roller. Impact roller construction refers to the impact roller through the loader traction, drive an impact wheel, use the weight of the impact wheel itself and the impact force when advancing, the cement pavement and roadbed are crushed and compacted.
