Underground raft foundation seamless connection mechanism and seamless connection construction method thereof
The invention provides an underground raft foundation seamless connecting mechanism which comprises a middle connecting section, pre-pouring concrete is poured on the two sides of the middle connecting section respectively, a plurality of connecting section steel bars are arranged in the middle connecting section, and longitudinal load-bearing steel bars corresponding to the connecting section steel bars respectively are arranged in the pre-pouring concrete on the two sides. The two ends of the connecting section reinforcing steel bar are connected with the corresponding longitudinal load-bearing reinforcing steel bars on the two sides respectively, and the connecting section reinforcing steel bar is further provided with a plurality of bent protrusions; a plurality of interface connecting steel bars are connected between the middle connecting section and the first pouring concrete on the two sides, high-ductility concrete comprising a plurality of layers is poured in the middle connecting section, and a plurality of holes distributed in a staggered mode are formed in the upper side and the lower side of the boundary between every two adjacent layers through soft materials. And the middle connecting section forms the complete raft foundation seamless connecting joint.
本公开提供了一种地下筏板基础无缝连接机构，其包括中间连接段，中间连接段两侧分别浇筑有先浇混凝土，中间连接段中设有若干个连接段钢筋，两侧先浇混凝土中均设有与连接段钢筋分别对应的纵向受力钢筋，连接段钢筋两端分别与两侧对应的纵向受力钢筋相连接，连接段钢筋还设有若干个弯折凸起；中间连接段与两侧先浇混凝土之间连接有若干个界面连接钢筋，中间连接段中浇筑有包括若干个分层的高延性混凝土，相邻两个分层之间的分界上下两侧通过软体材料形成有若干个交错分布的孔洞，中间连接段由此形成完整的筏板基础无缝连接接头。
