Description

An impact type road roughening machine

technical field

The utility model relates to a road surface roughening machine, in particular to an impact type road surface roughening machine.

Background technique

The long-term use of the current cement concrete pavement shows that the rough surface of the pavement is easy to be polished, and the anti-skid performance decays quickly. After one or two years of use, the surface anti-skid ability of the pavement basically disappears, and it needs to be maintained. ; Using the embossing and grooving process to make the cement concrete pavement anti-skid and anti-skid, the increase in the anti-skid resistance is small, and the edge of the groove is easy to break, and the mortar on the surface has poor wear resistance. In terms of roughening construction, the traditional chiseling and milling processes are used for surface treatment of concrete pavement. Under high-speed mechanical impact, micro-cracks are prone to occur inside the concrete, vibrating and loosening the protruding aggregates, and the cleaning is not thorough. The treated surface is uneven. The environmental pollution is serious, and the follow-up clean-up workload is heavy. In addition, due to the insufficient depth of the bridge deck cement concrete structure and the existence of laitance, a weak bonding surface is formed between it and the waterproof layer, and the interlayer stress increases and shear failure occurs, which eventually leads to the culprit of the asphalt concrete bridge deck disease. The survey shows that 78% of bridge deck diseases are related to poor interlayer bonding, which shows the importance of interlayer bonding to the durability of bridge decks. There are many reasons that affect the interlayer bonding, and the chiseling process is one of the basic factors that restrict the interlayer bonding effect. The quality of chiseling effect directly affects the bonding quality between cement concrete and asphalt concrete, weakens the ability to resist horizontal shear, and thus affects the service life of the bridge deck. In addition to low efficiency, the traditional artificial chiseling, brushing and mechanical grooving processes have the main problem of not being able to completely remove the laitance; although the milling process can solve the laitance problem, it is easy to cause loosening and damage to the concrete surface and form lines of different depths. The deep grooves are not conducive to surface cleaning and cause water retention on the bridge deck; while the construction roughening efficiency is high, but it will form a weak layer on the concrete surface.

At present, the commonly used ones are chisel machine, chisel machine, groove machine, small milling machine and road shot blasting machine. The chisel machine produces compressed air through the air compressor to drive the chisel head to chisel the road surface, and the mechanical shock force formed has too much impact on the road surface, which affects the service life of the road surface. Furthermore, the chisel works during the hot construction period, and the dust generated is very harmful to the environment and staff. Anti-skid treatment is also widely used with engraving machines, and transverse grooves are more widely used. It enables the road surface to produce better longitudinal anti-slip force, and can effectively ensure the lateral drainage of the road surface, but the rolling noise is relatively large, and the ability to prevent sideslip is not strong. When the road surface is wet, the car is prone to sideslip. Small milling machines are also often used to roughen cement concrete roads, but the damage to the concrete surface is relatively large, which is not conducive to wear resistance, and the construction does not meet environmental protection requirements. The current era is advocating a green, environmentally friendly and energy-saving society. Road shot blasting machines are also produced by many manufacturers as green and environmentally friendly road surface treatment equipment, which can be dust-free, soil-free, and pollution-free during construction operations. However, the recovery and recycling of shot blasting materials cannot be done as desired. When the machine passes through the construction joints of cement concrete pavement, the shot blasting materials will be lost, and the road shot blasting machine is expensive.
