Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of highway construction equipment, in particular to a wheeled self-propelled cement block crusher. Background Art
[0002] With the development of highway construction and the increase in traffic volume in my country, more and more cement slab pavements have entered the maintenance period and need to be rebuilt. There are three ways to deal with damaged cement slab pavements:
[0003] 1) Completely remove and discard the old pavement. This is a more thorough solution to deal with old cement pavement. However, this treatment method will not only have an adverse impact on the environment, but also the old cement pavement itself has a certain material strength and can be recycled. If it is discarded, it will waste resources.
[0004] 2) Cement concrete pavement rubble technology is a pavement reconstruction technology that helps crushers break cement concrete pavement into a certain size. The pavement structure after crushing by rubble technology is internally embedded and densely combined, and can be used as a stable and flexible base. After rubble, the surface layer particle size is usually less than 7.5cm, the middle layer particle size is usually less than 22.5cm, and the bottom particle size is usually less than 37.5cm. The biggest feature of this method is that it makes full use of the original pavement materials. The utilization rate of waste materials after crushing reaches more than 95%, which reduces environmental pollution, reduces construction costs, and basically solves the problem of reflective cracks.
[0005] 3) Use a pickaxe to break the old pavement cement slab material into large cement concrete blocks and send them to the crushing plant. After being crushed, they are transported back to the site for use as crushed stone materials.
[0006] The second treatment method is that it is more difficult to crush the cement board when the cement board is thick or the cement grade is high and the cement board is hard. At this time, a walking cement block crusher is needed to achieve the effect of laying the base layer as soon as it is crushed.
[0007] The third treatment method has the advantage that it can effectively utilize the crushed cement board materials and can adjust the particle size of the crushed cement board materials as required. However, since it needs to rely on vehicles to transport it back and forth, it leads to increased fuel costs, increased construction costs, and pollution to the environment. Utility Model Content
