Duct grouting auxiliary device and grouting process
The invention discloses a duct grouting auxiliary device and a grouting process, and belongs to the technical field of prestressed duct grouting processes. Through the technical key points, the duct grouting auxiliary device comprises a slurry feeding pipeline connected with a slurry pump, a grouting pipe connected with the slurry feeding pipeline, and an auxiliary plugging plate detachably arranged at the end part of the grouting pipe, the auxiliary plugging plate is larger than the plugging hole, a grout outlet coaxial with the grouting pipe is formed in the auxiliary plugging plate in a penetrating mode, a penetrating hole matched with an anchor rod extending out of a duct is further formed in the auxiliary plugging plate in a penetrating mode, and an elastic extrusion layer is fixedlyarranged on the plate face of the auxiliary plugging plate. By means of the scheme, the auxiliary plugging plate abuts against a beam body on the peripheral side of the plugging hole after the anchorrod penetrates through the penetrating hole, the elastic extrusion layer on the plate face of the auxiliary plugging plate is used for deforming, then the auxiliary sealing plate makes close contact with the beam body, and finally cement conveyed out through the grouting pipe can be rapidly filled in the plugging hole.
本发明公开了一种孔道压浆辅助装置及压浆工艺，属于预应力孔道压浆工艺的技术领域，其技术要点在于：一种孔道压浆辅助装置，包括连接有泥浆泵的送浆管道、与送浆管道连接的注浆管以及可拆设置于所述注浆管端部的辅助封堵板，所述辅助封堵板大于封堵孔，所述辅助封堵板贯穿开设有与所述注浆管同轴的出浆孔，所述辅助封堵板上还贯穿开设有与伸出孔道的锚杆所适配的穿孔，所述辅助封堵板板面上固定设置有弹性挤压层。通过上述方案，实现了辅助封堵板在锚杆利用穿孔穿过后将抵触在封堵孔周侧的梁体上，并利用其板面上的弹性挤压层进行形变进，进而使辅助密封板与梁体进行紧密接触，最终使得通过注浆管送出的水泥可在封堵孔内快速进行填充。
