According to the method, the diameter of a pile hole drilled by the drill bit can be adjusted, then different use requirements can be met, meanwhile, it is guaranteed that in the drilling-down process of the drill bit, mud and stones in soil can be prevented from blocking the grout conveying pipe, and the construction efficiency is improved.

The invention discloses a high-pressure rotary grouting pile drill bit based on the application of road and bridge construction, which includes a rod body and a conical head. components; the outer wall of the rod body is also provided with a number of drill blades, when the movable assembly moves towards the direction of the cone head, the movable assembly can push the drill blades to move away from the rod body, and the side walls of the drill blades facing the direction of the cone head There is a baffle; there is also a telescopic tube in the cavity of the rod body, one end of the telescopic tube is connected with the slurry delivery pipe, and the other end is provided with a joint. One end of the assembly is facing the drill blade, and the other end is located in the cavity of the rod body. The invention can adjust the diameter of the pile hole drilled by the drill bit to meet different use requirements, and at the same time ensure that the drill bit can prevent the mud and stones in the soil from blocking the slurry delivery pipe during the drilling process, thereby improving the construction efficiency.

The invention provides a Y-shaped three-way injection mold with a simple ejection structure. The Y-shaped three-way injection mold comprises a lower mold seat, pad feet, a fixed template fixing plate, a fixed template, a movable template, a movable template fixing plate and an upper mold seat; a gate sleeve is arranged in the center of the upper mold seat; a runner is arranged along the center of the gate sleeve; a plurality of groups of Y-shaped cavities are formed in the fixed template; each group of the Y-shaped cavities comprises a positive Y-shaped part and an inverted Y-shaped part which are arranged in opposite directions; the movable template fixing plate and the fixed template fixing plate are both provided with a first mold core and a second mold core; the movable template and the fixed template are each provided with a third mold core; a first spring is fixed between the fixed template and the fixed template fixing plate; and the lower mold seat is provided with a straight ejection mechanism; and the straight ejection mechanism is composed of an ejector pin, a cushion plate and third springs. According to the Y-shaped three-way injection mold with the simple ejection structure, by reasonably arranging injection parts, a workpiece is ejected by using the simplest ejection mechanism, so that the ejection effect is better, and the production cost is saved.
