Pipe sinking method
The invention belongs to the technical field of pipe sinking construction, and discloses a pipe sinking method. The pipe sinking method comprises the steps that S1, a balance weight body with the gravity being G2 is additionally arranged on a steel pipe with the gravity being G1, then the two ends of the steel pipe are plugged, the buoyancy borne by the steel pipe is F1, and F1 is smaller than G1 + G2; s2, a floating body with the buoyancy being F2 is arranged on the steel pipe, wherein F1 + F2 is larger than or equal to G1 + G2; s3, the steel pipe is moved into water; s4, the position of the steel pipe floating on the water surface is adjusted, the steel pipe is moved to the position above the underwater foundation trench, and then the steel pipe is connected with hoisting equipment; and S5, the floating body is dismantled, and the steel pipe sinks into the foundation trench under the combined action of the gravity G1, the gravity G2, the buoyancy F1 and the pulling force of the hoisting equipment. According to the pipe sinking method, the load of the hoisting equipment is greatly reduced, and the problem that the steel pipe is instably sunk due to insufficient hoisting force of the hoisting equipment is solved, so that the potential safety hazard is reduced.
本发明属于沉管施工技术领域，公开了一种沉管方法。该沉管方法包括：S1、在重力为G1的钢管上加装重力为G2的配重体，随后将钢管的两端封堵，钢管受到的浮力为F1，其中F1＜G1+G2；S2、在钢管上设置浮力为F2的浮体，其中F1+F2≥G1+G2；S3、将钢管移动至水中；S4、调整漂浮在水面上的钢管的位置，使钢管移动至水底基槽的上方，随后将钢管与起重设备连接；S5、拆除浮体，使钢管在重力G1、重力G2、浮力F1以及起重设备的拉力的共同作用下沉放至基槽中。该沉管方法极大地降低了起重设备的负载，解决了起重设备因吊力不足而导致钢管沉放不稳定的问题，从而降低了安全隐患。
