Prestressed pipe pile bottom grouting equipment and using method thereof
The invention relates to the technical field of grouting equipment, and discloses prestressed pipe pile bottom grouting equipment and a using method thereof, and the prestressed pipe pile bottom grouting equipment comprises a device main body and a high-pressure grouting pump main body. By arranging the pile end bearing capacity improving mechanism, in actual use, by adopting the design, the soil blockage phenomenon can be effectively avoided through the conical pile seat body, grout is injected into a soil body near the pile end through the vertical grouting channel, the transverse grouting channel and the inclined grouting channel, primary bearing capacity improvement is formed, and the bearing capacity of the pile end is improved. Slurry is injected into the first grouting capsule and the second grouting capsule, a pile end expanding head can be formed, the slurry is injected towards the surrounding stratum of the pile side through the vertical grouting channel, the transverse grouting channel and the inclined grouting channel, the pile body and the pile bottom expanding head can be tightly combined, and meanwhile, the grouting effect is good. The pile bottom expanding head and the stratum around the pile bottom are more compact and higher in strength, and finally the ultimate bearing capacity of the prestressed pipe pile body is greatly improved.
本发明涉及注浆设备技术领域，且公开了一种预应力管桩桩底注浆设备及其使用方法，包括包括装置主体和高压注浆泵主体。本发明通过设有桩端承载力提升机构，采用这种设计在实际使用中，通过锥形桩座本体能够有效避免土塞现象，利用竖向注浆通道、横向注浆通道和倾斜向注浆通道来将浆液注入桩端附近的土体，形成初步的承载力提升，通过将浆液注入第一注浆胶囊和第二注浆胶囊的内部，能够形成桩端扩大头，并且通过竖向注浆通道、横向注浆通道和倾斜向注浆通道将浆液朝向桩侧周围地层注入，能够使桩身和桩底扩大头紧密结合，同时，使桩底扩大头和桩底桩周围地层更加密实，强度更高，最终使预应力管桩主体的极限承载力大幅度提高。
