Horizontal steel bar planting structure and construction method
The invention discloses a horizontal steel bar planting structure and a construction method. The horizontal steel bar planting structure comprises a planting steel bar and horizontal planting steel bar hole channels, the parts, close to the open ends, of the steel bar planting hole channels are horizontal equal-straight sections with an unchanged hole diameter, and the parts close to the closed ends are wedge-shaped chambering widening sections with a gradually increased hole diameter, the opening ends are arranged on a planting steel bar base body structure, a sealing cover with a grouting opening and a grout outlet is arranged on the planting steel bar base body structure, a planting steel bar inserting hole is formed in the center position of the grouting opening sealing cover, and a gap between the planting steel bar and the planting steel bar hole channel is filled by injecting a non-shrinkage cement-based grouting material in a pressing manner. During construction, the steel bar planting hole channel is drilled firstly, and the inner surface of the steel bar planting hole channel is wetted; then, the grouting opening sealing cover is arranged, and planting steel bar is inserted; and the non-shrinkage cement-based grouting material is pressed from the grouting opening to be full, and after initial setting, the sealing opening of the grouting opening and redundant slurry are detached. The horizontal steel bar planting structure has good anchoring performance, durability and operability, and the anchoring performance is ensured on the premise that grouting compactness is ensured.
本发明公开了水平植筋构造及施工方法，包括植入钢筋和水平的植筋孔道；植筋孔道靠近开口端的部分为孔径不变的水平等直段段，靠近封闭的部分为孔径逐渐变大的楔形扩孔变宽段；开口端设于植筋基体结构；植筋基体结构上设有带灌浆口、出浆口的密封盖；灌浆口密封盖的中心位置设有植筋插入孔；植入钢筋与植筋孔道之间间隙通过压注无收缩水泥基灌浆料至饱满。施工时，先钻置植筋孔道，并润湿植筋孔道的内表面；然后设置灌浆口密封盖，并插入植入钢筋；从灌浆口压入无收缩水泥基灌浆料至饱满，待初凝后，拆卸灌浆口密封口和多余浆料。本发明既具有良好的锚固性能、耐久性，也具有良好的操作性，在确保灌浆密实的前提下确保锚固性能。
