Problems solved by technology

Of these two treatment methods, the former wastes manpower and material resources, the treatment efficiency is low, and the appearance of the treated road surface is poor; The force is always concentrated in a small area and cannot be evenly distributed. It is difficult to uniformly treat all areas of the road surface, which leads to a large difference in the roughness of different areas of the road surface after cleaning, and the efficiency of this treatment method is not ideal.

example 1

[0018] see Figure 1~4 , the laitance cleaning device in this example includes a frame 1, and the laitance scraper 2 and blower 3 are arranged on the frame 1 from front to back;

[0019] see Figure 1~4 , the frame 1 includes a rectangular frame 1-3 inclined to the rear and upward, the front ends of the two sides of the rectangular frame 1-3 vertically extend downwards a support rod 1-6, between the two support rods 1-6 A scraper beam 1-1 close to the ground 6 is provided. The scraper beam 1-1 is 2.5 cm high, 100 cm long, and has a rectangular cross section. The beam at the rear end of the rectangular frame 1-3 doubles as the handle 1-5 of the device. The lower heads of the two support rods 1-6 are respectively provided with a baffle beam 1-2 and an auxiliary baffle beam 1-7, and the two baffle beams 1-2 extend to the front of the rectangular frame 1-3 sides respectively, and are connected with the machine. The forward direction of the frame 1 is at an included angle of 45°, ...

example 2

[0024] Example 2 (this example is the experimental example of the effect of the floating slurry cleaning device in the verification example 1)

[0025] 1. Purpose of the experiment

[0026] Verify the use effect of the floating slurry cleaning device described in Example 1.

[0027] 2. Experimental method

[0028] Get two sections of road surface with a length of 50m respectively in the experimental road section with a width of 10m (two lanes including shoulders), one section is used as the experimental section, and the other section is used as the comparison section. The existing hydraulic flushing method cleans up the laitance. Record the construction time and labor quantity respectively.

[0029] After the maintenance of the two sections of pavement, several points were randomly selected on the pavement to investigate the structural depth.

Abstract

The invention discloses a laitance removing device suitable for a semi-flexible pavement. The laitance removing device comprises a rack and an air blower. The rack comprises a rectangular frame. Two supporting rods extend downwards vertically from the front ends of the two sides of the rectangular frame respectively. A scraper beam close to the ground is arranged between the two supporting rods. The lower portions of the two supporting rods are each provided with a baffle beam. The two baffle beams extend to the front portions of the two sides of the rectangular frame respectively and the tail ends of the baffle beams are each provided with a guide wheel borne on the pavement. A rubber baffle is arranged below each baffle beam. A laitance scraper is arranged on the rear side face of the scraper beam. The bottom of the laitance scraper is tightly attached to the pavement and the laitance scraper is provided with a slope extending from the rear edge of the upper surface of the scraper beam to the position, behind the scraper beam, of the pavement. The air blower is arranged on the rectangular frame, an exhaust duct of the air blower extends obliquely to the position, behind the slope on the laitance scraper, of the pavement and to the position close to the lower edge of the slope, and the tail end of the exhaust duct is parallel to the laitance scraper.

Description

technical field [0001] The invention relates to equipment for trimming laid unsolidified materials in road surface construction, which is suitable for restoring the structural depth of the road surface so that the road surface can obtain good skid resistance. Background technique [0002] The semi-flexible pavement is a pavement formed by pouring a special slurry (hereinafter referred to as cement mortar) with cement as the main component into the open-graded large-void parent asphalt mixture. This pavement has higher flexibility than cement concrete pavement and rigidity higher than asphalt concrete pavement, taking into account the advantages of both rigid and flexible pavement, from anti-rutting, anti-moving, reducing expansion joints and improving the stress relaxation performance of pavement materials, etc. Significantly improved road performance. Compared with the flexible pavement, the semi-flexible pavement has better high temperature stability, low temperature crac...
