The invention provides a grouting device for highway bridge construction, and relates to the technical field of highway bridge construction. A grouting device for highway bridge construction comprises a rack, a drilling assembly and an injection assembly. The drilling assembly comprises a drill rod and a rotating piece, the drill rod is arranged on the rack in a penetrating mode, and the rotating piece is connected with the drill rod. The injection assembly comprises an injection pipeline, and a drill bit is arranged at the end, away from the injection pipeline, of the drill rod. An adjusting rod and a plugging head are arranged in the injection channel in a penetrating mode, and the adjusting rod is rotationally arranged in the drill rod. One end of the adjusting rod can extend out of the drill rod, and the plugging head is rotationally arranged in the drill rod. A plurality of L-shaped through holes are formed in the plugging head, the L-shaped through holes comprise vertical holes parallel to the drill rod and transverse holes parallel to the drill rod, the vertical holes are communicated with the transverse holes, a plurality of outlets are formed in the side wall of the drill rod in the circumferential direction, and the outlets can be communicated with the transverse holes in a one-to-one correspondence mode. According to the grouting device for highway bridge construction, soil and other substances can be prevented from entering the corresponding drill rods, and the problem of blockage is prevented.
本发明提出了一种公路桥梁施工用注浆装置，涉及公路桥梁施工技术领域。一种公路桥梁施工用注浆装置，包括机架、钻进组件和注入组件。钻进组件包括钻杆和转动件，钻杆穿设设置于机架上，转动件与钻杆连接。注入组件包括注入管路，远离注入管路的钻杆一端设置有钻头。注入通道内穿设有调节杆和封堵头，调节杆转动设置于钻杆内。调节杆的一端能伸出钻杆，封堵头转动设置于钻杆内。封堵头上开设有多个L型通孔，L型通孔包括与钻杆平行的竖向孔和与钻杆平行的横向孔，竖向孔与横向孔连通，钻杆的侧壁上周向开设有多个出口，多个出口能与横向孔一一对应连通。该公路桥梁施工用注浆装置能够避免泥土等物质进入到对应的钻杆内，防止出现堵塞的问题。
