Cast-in-place pile post-grouting mechanism beneficial to uniform distribution of cement paste and construction technology of cast-in-place pile post-grouting mechanism
The cast-in-place pile post-grouting mechanism comprises a reinforcing mesh and a plurality of grouting rings, the grouting rings serve as a part of the reinforcing mesh, the outer walls of the inner rings of the grouting rings are fixedly connected with the reinforcing mesh, the grouting rings are distributed on the reinforcing mesh at equal intervals and are coaxially distributed, and the grouting rings are fixedly connected with the reinforcing mesh. The grouting device comprises a plurality of grouting rings, a plurality of grouting heads and two grouting pipes, the grouting heads are arranged on the side wall of each grouting ring at equal intervals, the grouting heads are parallel to the radius direction of the grouting rings, the heads of the grouting heads are inserted into a soil layer on the periphery of the grouting rings, each grouting pipe is connected with the same part of each grouting ring in an inserted mode at the same time, and the grouting pipes are connected with the grouting rings in an inserted mode. The grouting ring is provided with inserting holes corresponding to the grouting pipes, the portion, connected with the grouting ring, of each grouting pipe is provided with a grouting opening, and the grouting pipes and the grouting heads are staggered. The post-grouting mechanism has the advantages that the grouting mechanism in the post-grouting technological process is optimized, the cement distribution uniformity is improved, and meanwhile the post-grouting cost is reduced.
本发明涉及一种利于水泥浆均匀分布的灌注桩后注浆机构及其施工工艺，其包括钢筋网，多个注浆环，所述注浆环作为所述钢筋网的一部分，注浆环的内圈外壁与钢筋网固接，多个注浆环等间距分布在钢筋网上，多个注浆环同轴分布，多个注浆头，多个所述注浆头等间距设置在每个所述注浆环的侧壁上，多个注浆头平行于注浆环的半径方向，多个注浆头的头部插入注浆环周边土层之中，两根注浆管，每根所述注浆管同时与每个所述注浆环的相同部分插接，注浆环上对应注浆管开设有插接孔，每根注浆管与注浆环连接的部分处开设有注浆口，注浆管与注浆头交错开。本发明具有优化后注浆工艺过程中的注浆机构，提高水泥分布的均匀性的同时降低后注浆成本的效果。
