Description

Technical Field

[0001] The utility model relates to the technical field of road grouting, in particular to a road water-stabilizing layer construction edge grouting device. Background Art

[0002] In road construction, especially when laying the water-stable layer, the water-stable edge grouting machine plays an important role. This equipment is specially used for laying cement-stabilized gravel base. By grouting on the edges of both sides of the road, it effectively improves the density and strength of the base edge and the bonding surface, ensuring the construction quality. The main structure of the water-stable edge grouting machine includes a grouting bucket installed at the tail of the paver. The grouting bucket is equipped with a mixing device and a grouting device. The end of the grouting hose is pulled to the edge of the road water-stable layer by adjusting the support frame to achieve direct grouting. This process helps to ensure the stability of the edge after demolding, prevent edge collapse, and make the line smoother and more beautiful.

[0003] When using a grouting device to grout the edge of the water-stabilizing layer of a road, the slurry sprayed through the grouting hose to the slurry outlet is relatively concentrated, which will cause the edge of the water-stabilizing layer to be washed out of the groove, which is not conducive to the uniform distribution of the grouting liquid at the edge, affecting the construction effect, resulting in the need for additional leveling operations later, and increasing the workload of construction. Utility Model Content

The deceleration plate is a Y-shaped plate body with a sharp top and a forked bottom. A limit plate is fixedly installed on the rear end of the fixed rod, and the limit plate can slide and rotate relative to the support member. The fixed rod is slidably connected to the positioning member and the positioning member can lock the fixed rod.

The cross bar is arranged on the bottom front side of the grouting bucket by the positioning bolts, the vertical bar is fixed to one end of the cross bar by the positioning bolts, and the bottom of the vertical bar is fixedly connected to the top of the grouting nozzle.

[0012] The splash shield includes a square frame, a slide plate is fixedly installed on one side of the square frame, the fixed plate is fixedly installed on the bottom of one side of the grouting nozzle, and the fixed plate and the slide plate are slidingly connected, a screw is rotatably installed inside the fixed plate, and the screw and the slide plate are threadedly connected, and an oblique flow groove is opened on the surface of the square frame.

It will flow down along the outside of the splash baffle, and the angle and horizontal position of the slow baffle can be quickly adjusted by moving the support plate, and the spacing between each group of slow baffles and the side inclination angle of the contact slurry can be controlled, so that when the slurry flows down from the grouting nozzle and contacts the slow baffle, the flow rate drops sharply and flows down along the surface of the slow baffle and the surface of the splash baffle. The range of the slurry injected to the edge of the road water-stabilizing layer is expanded and controlled by the slow baffle, which is conducive to the uniform distribution of the grouting liquid at the edge, reducing the impact force and avoiding the appearance of grooves.
