Post-grouting device for prestressed concrete pipe pile
The invention relates to the technical field of building construction, and discloses a prestressed concrete pipe pile post-grouting device which comprises a grouting device body, a main grouting channel is formed in the grouting device body, the bottom of the main grouting channel is of a three-fork-shaped structure, and first check valves are arranged in forked parts on the two sides of the bottom of the main grouting channel correspondingly; pile bottom grouting channels penetrating through the side walls of the two sides of the grouting device body are further connected to the forked parts on the two sides of the bottom of the main grouting channel, pile side grouting channels arranged in a three-fork-shaped structure are further formed in the grouting device body, and the forked parts on the two sides of the pile side grouting channels penetrate out of the positions, close to the ends of the two sides, of the top face of the grouting device body; the middle bifurcated part of the pile side grouting channel is communicated with the middle bifurcated part of the bottom of the main grouting channel, and a second check valve is further connected into the middle bifurcated part of the pile side grouting channel; the method has the characteristics that the bearing capacity effect of the pipe pile after construction reaches the standard, and construction is simple.
本发明涉及建筑施工技术领域，公开了一种预应力混凝土管桩后注浆器，包括注浆器本体，注浆器本体内部设有主注浆通道，主注浆通道的底部呈三叉状结构设置，主注浆通道底部两侧的分叉部内均设有第一逆止阀，主注浆通道底部两侧的分叉部上均还接有分别贯穿注浆器本体两侧侧壁的桩底注浆通道，注浆器本体内部还设有呈三叉状结构设置的桩侧注浆通道，桩侧注浆通道的两侧分叉部分别自注浆器本体顶面贴近其两侧端部的位置处贯穿出，桩侧注浆通道的中部分叉部与主注浆通道底部的中部分叉部连通在一起，桩侧注浆通道的中部分叉部内还接有第二逆止阀；本发明具有确保施工后管桩承载力效果达标、施工简单的特点。
