Grouting joint bar compaction grouting sleeve precast concrete wall and construction method
The invention discloses a grouting joint bar compaction grouting sleeve precast concrete wall and a construction method, the grouting joint bar compaction grouting sleeve precast concrete wall comprises a plurality of sections of precast shear walls connected up and down, the top of each precast shear wall is provided with a plurality of grouting sleeves, the side surface of each precast shear wall is provided with a grouting port and a grout outlet which respectively communicate with a inner cavity of each grouting sleeve, a plurality of connecting steel bars corresponding to the grouting sleeves in a one-to-one mode are arranged at the bottom of the precast shear wall in a protruding mode, the tops of the connecting steel bars are connected with the bottoms of the grouting sleeves, When the sections of precast shear walls are spliced, the grouting sleeves are filled with high strength grouting materials firstly, then, the connecting steel bars protruding out of the bottom of the precast shear wall of the upper section are inserted into grouting sleeves on the top of the precast shear wall of the lower section, and the connecting steel bars and the grouting sleeves are connected into a whole; by means of the method, it can be guaranteed that all the sleeves are filled with grouting materials densely, the construction difficulty and quality risks of pressure grouting in a traditional mode are greatly reduced, the defects such as cavities caused by non-dense grouting do not exist, and it is guaranteed that force transmission at the connecting position is safe and reliable.
本发明公开了一种灌浆插筋挤密灌浆套筒预制混凝土墙及施工方法，包括多段上下连接的预制剪力墙，预制剪力墙的顶部设置有若干灌浆套筒，预制剪力墙的侧面设置有分别与各个灌浆套筒内腔相通的注浆口和出浆口，预制剪力墙的底部凸出有若干与各个灌浆套筒一一对应的连接钢筋，连接钢筋的顶部连接灌浆套筒的底部，拼接各段预制剪力墙时，先在灌浆套筒内充满高强灌浆料，然后将上段的预制剪力墙的底部凸出的连接钢筋插入下段的预制剪力墙的顶部灌浆套筒内，将连接钢筋和灌浆套筒连接成整体；本发明可以确保所有套筒内的灌浆料均填满密实，大大降低传统方式压力注浆的施工难度和质量风险，不会存在注浆不密实的空洞等缺陷，确保连接位置的传力安全可靠。
