Box girder prestressed duct grouting compacting device and compacting method thereof
The invention discloses a box girder prestressed duct grouting compacting device and a compacting method thereof, and relates to the technical field of prefabricated box girder prestressed duct grouting, in particular to the box girder prestressed duct grouting compacting device and the compacting method thereof. Comprising a threaded pipe matched with a grouting hole of an anchorage device at the end of a box girder, and the threaded pipe is in threaded connection with the grouting hole of the anchorage device at the end of the box girder and in threaded connection with a two-way valve; the two-way valve is connected with the male connector, the outer diameter of the limiting hollow pipe is matched with the inner diameter of the threaded pipe, and the height of the limiting hollow pipe is matched with the depth of the mud jacking hole. The outer diameter of the hollow lead screw is smaller than the inner diameter of the threaded pipe, a female connector matched with the male connector is arranged at the front end of the hollow lead screw, and a fixing nut is arranged at the rear end of the hollow lead screw. The rubber elastic plunger is in sliding connection with the inner wall of the threaded pipe and then is tightly connected with the front end of the threaded pipe, and the rubber elastic plunger is in contact connection with the limiting hollow pipe. The method has the positive effects that the grouting quality is improved, the compactness is improved, and meanwhile, the construction cost is saved.
箱梁预应力孔道压浆密实装置及其密实方法，涉及预制箱梁预应力孔道压浆技术领域，特别是涉及一种箱梁预应力孔道压浆密实装置及其密实方法。包括与箱梁端部锚具的压浆孔相适配的螺纹管，螺纹管螺纹连接箱梁端部锚具的压浆孔，螺纹管螺纹连接二通阀门；二通阀门连接公接头，限位空心管的外径与螺纹管的内径相适配，限位空心管的高度与压浆孔的深度相适配；空心丝杆的外径小于螺纹管的内径，空心丝杆的前端设置有与公接头相适配的母接头，空心丝杆的后端设置有固定螺母；橡胶弹性柱塞与螺纹管内壁滑动连接后，与螺纹管前端紧密连接，且橡胶弹性柱塞与限位空心管接触连接。本发明具有提高压浆质量，提高密实性，同时节约施工成本的积极效果。
