Steel pile body for construction of steel pipe grouting pile capable of sinking pipe and grouting at same time
A steel pile body for steel pipe grouting pile construction capable of achieving pipe sinking and grouting at the same time comprises a steel pipe and a pile cap which is fixedly installed at the top of the steel pipe and facilitates pressure applying and pile sinking. The conical pile tip is arranged at the bottom of the steel pipe and used for breaking the soil body; the blind plate is arranged between the conical pile tip and the steel pipe, the blind plate and the steel pipe are concentrically arranged, the diameter of the blind plate is larger than that of the steel pipe, and as the steel pile body sinks into a foundation soil body, a base hole larger than the diameter of the steel pipe is formed due to the fact that the diameter of the blind plate is larger than that of the steel pipe; the lateral grout outlet is formed in the position, close to the blind plate, of the bottom of the steel pipe, the grouting hole is formed in the position of the pile cap on the upper portion of the steel pipe, and in the construction of pipe sinking and grouting at the same time, cement mortar is injected from the grouting hole and flows out of the steel pipe from the grout outlet to be used for rapidly filling a gap between the steel pipe and the hole wall of the base hole. Soil around the pile is effectively prevented from loosening and falling into gaps. Therefore, the composite pile body with the steel cylinder internally and externally wrapped with the cement mortar reinforcing layer is formed.
一种边沉管边注浆的钢管注浆桩施工用钢桩本体，包括钢管，桩帽，固定装在钢管的顶部，便于施压沉桩；椎形桩尖，设在钢管底部设有，用于破开土体；盲板，设置在椎形桩尖与钢管之间设有，盲板与钢管同心设置，盲板的直径大于钢管直径，随着钢桩本体沉入地基土体中，由于盲板的直径大于钢管直径，形成大于钢管直径的基孔；出浆孔和注浆孔，在钢管底部靠近盲板处设有侧向出浆孔，在钢管上部桩帽处设有注浆孔，在边沉管边注浆施工中，水泥砂浆由注浆孔注入，从出浆孔处往钢管外部流出，用以快速填充钢管与基孔孔壁之间的间隙，有效防止桩周土松散落入空隙中。从而形成钢筒内外均匀包裹水泥砂浆加固层的复合桩体。
