Description

Technical Field

[0001] The utility model relates to the technical field of road construction equipment, in particular to a slurry scraping device for a perfusion type semi-flexible road surface. Background Art

[0002] Semi-flexible pavement is a pavement paved by pouring cement-based grouting material into a large-void matrix asphalt mixture pavement. It is a new type of pavement structure material that is both rigid and flexible. It combines the advantages of high bearing capacity, high rigidity, and strong resistance to permanent deformation of cement pavements with the advantages of no joints, good driving comfort, and good crack resistance of asphalt pavements. At the same time, the material cost is low, and it has gradually become one of the important materials for solving rutting problems in asphalt pavements.

[0003] Compared with the traditional asphalt pavement construction process, the semi-flexible pavement construction process is complicated. The difference is that cement-based grouting material is poured into the connected voids of the large-void matrix asphalt mixture. In order to ensure the filling rate of the internal voids of the semi-flexible pavement, during the construction process, the actual amount of cement-based slurry spread is more than the theoretical amount of slurry required to fill the internal voids of the large-void matrix asphalt mixture. If the excess slurry is not processed, the cement-based slurry will harden on the road surface to form a thin layer of cement slurry. When it is used as the surface layer, the anti-skid structural depth is greatly reduced, seriously affecting driving safety and also affecting the appearance. When it is used as the middle and lower layers, the thin layer of cement slurry reduces the interlayer bonding between the semi-flexible pavement material and the asphalt pavement, seriously affecting the integrity of the pavement structure. Therefore, removing the excess slurry on the surface of the large-void matrix asphalt mixture and ensuring that it has sufficient structural depth are the key to the construction of semi-flexible pavement materials. However, there is currently a lack of construction equipment for removing the slurry and restoring the structural depth. It is mainly completed by a long brush, which is time-consuming and labor-intensive, inefficient and ineffective. Utility Model Content

[0022] The utility model provides a grouting device for a poured semi-flexible pavement: comprising a mobile body 101, a reversing mechanism 102, a driving mechanism 103 and a working assembly, wherein the working assembly comprises a connecting frame 104, a mounting frame 105, a grouting strip 106, a wire brush holder 107, a control member, a limiting member and an auxiliary member, wherein the control member comprises a control screw 108 and a control motor 109, and the limiting member comprises a moving plug 110 and an extrusion spring 111, wherein the moving plug has an insertion boss 112 and an inclined boss 113. The above-mentioned solution solves the problem that the construction process of a semi-flexible pavement is complicated compared to the traditional asphalt pavement construction process. The difference is that cement-based grouting material is poured into the connected gaps of the large-void matrix asphalt mixture. In order to ensure the filling rate of the internal gaps of the semi-flexible pavement, During the construction process, the actual amount of cement-based slurry spread is more than the theoretical amount of slurry required to fill the internal voids of the large-void matrix asphalt mixture. If the excess slurry is not processed, the cement-based slurry will harden on the road surface to form a thin layer of cement slurry. When it is used as the surface layer, the anti-skid structural depth is greatly reduced, seriously affecting driving safety and also affecting the appearance. When it is used as the middle and lower layers, the thin layer of cement slurry reduces the interlayer adhesion between the semi-flexible pavement material and the asphalt pavement, seriously affecting the integrity of the pavement structure. Therefore, removing excess floating slurry on the surface of the large-void matrix asphalt mixture and ensuring that it has sufficient structural depth are the key to the construction of semi-flexible pavement materials. However, there is currently a lack of construction equipment for removing floating slurry and restoring structural depth, and it is mainly completed by long brushes, which is time-consuming and labor-intensive, inefficient and ineffective.

When the user drives the control screw 108 to rotate through the control motor 109, the mounting frame 105 can be driven, and then the mounting frames 105 on both sides and the scraper bars 106 and the wire brush holder 107 on the mounting frames 105 can be adjusted in height.

[0026] When the grouting type semi-flexible pavement scraper device of the present embodiment is in use, the mobile body 101 cooperates with the reversing mechanism 102 and the driving mechanism 103 to drive the entire device to move, and then the scraper strip 106 on the front side of the mobile body 101 and the wire brush holder 107 are used to perform two scraping operations. The on-site scraping construction is mainly implemented through the following steps: Step 1: On-site mixing of cement-based grouting material for semi-flexible pavement, testing the fluidity of the grouting material to meet the technical requirements, and using a pipeline pump to the large-void matrix asphalt mixture construction area. The slurry can self-level and penetrate under the action of gravity until the slurry no longer seeps; Step 2: After the grouting material is poured and before the initial setting, check the scraping device, and start the scraping operation after it is normal. The entire device drives the entire grouting material in cooperation with the reversing mechanism 102 and the driving mechanism 103. The device moves forward, and the operator controls the forward, turning or backward movement through the pushing frame, and then drives the mounting frame 105 on the front and rear sides and the scraper bar 106 and the wire brush holder 107 to automatically descend to the road surface through the control motor 109 and the control screw 108. Step 3: Remove the excess floating slurry on the road surface through the scraper bar 106, and then further process the slurry that is difficult to remove and tightly attached to the surface by the scraper bar 106 through the wire brush holder 107, and at the same time, the structural depth of the large-void matrix asphalt mixture can be restored to a certain extent; when the road surface is uneven, the scraping system automatically controls the lifting and lowering of the composite scraper strip brush through the intelligent lifting motor to ensure that the strip brush is always in contact with the road surface, thereby ensuring the scraping effect and construction efficiency, and realizing that the scraping of semi-flexible road surfaces can be carried out more conveniently and quickly through the provided components.
