Directional grouting structure and deviation rectifying system of pier roadbed
The invention discloses a directional grouting structure which is used for directional grouting in a grouting hole and comprises a casing material poured in the grouting hole, a flow guide pipe, a grouting pipe and sealing plugs, wherein the flow guide pipe is arranged in the grouting hole, a plurality of rows of slurry spraying openings for directional spraying are formed in the flow guide pipe,and the flow guide pipe is wrapped by the casing material; the grouting pipe is arranged in the flow guide pipe, and a slurry outlet is formed in the grouting pipe; and the two sealing plugs are fixedto the grouting pipe, the slurry outlet is located between the two sealing plugs, the grouting pipe can move in the flow guide pipe in a sliding mode through the sealing plugs, a slurry spraying cavity is formed between the two sealing plugs and the flow guide pipe, and the slurry spraying cavity is connected with at least one row of slurry spraying openings. Meanwhile, the invention further provides a deviation rectifying system for a pier roadbed. The directional grouting structure and the deviation rectifying system of the pier roadbed have the advantage that damage to surrounding existingbuildings is prevented in horizontal deviation renovation of the pier roadbed.
本申请公开了一种定向注浆结构，用于在注浆孔内定向注浆，包括套壳料，浇筑在所述注浆孔中；导流管，设置在所述注浆孔中，所述导流管上形成有定向喷射的多排喷浆口，所述导流管被所述套壳料所包裹；注浆管，设置在所述导流管内，所述注浆管上形成有出浆口；密封塞，两所述密封塞固定在所述注浆管上，所述出浆口位于两所述密封塞之间，所述注浆管通过所述密封塞可滑动地在所述导流管内移动，两所述密封塞与所述导流管之间形成喷浆腔，所述喷浆腔与至少一排所述喷浆口连通。同时还提供一种桥墩路基的纠偏系统。本申请的一种定向注浆结构及桥墩路基的纠偏系统，具有在桥墩路基水平偏移整治中，防止对周边既有建筑造成损坏的优点。
