before the concrete jacking construction, the joint of the pump pipe outside the column is leaned against the column body and is fastened through a bolt fixed on a built-in reinforcing plate of the column, so that the lateral displacement of the pump pipe is reduced;
step 3, connecting the stop valve and the pump pipe joint with the pump pipe joint outside the column in sequence;
step 4, the dismantling step comprises:
step 4.1, knocking the stop valve downwards after the concrete is jacked to a specified elevation, and disconnecting the connection between the concrete on the column side and the pump workshop;
step 4.2, knocking the pump pipe joint outside the column to enable the joint round hole and the column body round hole to be completely staggered, and disconnecting the connection between the concrete in the column and the pump pipe joint;
4.3, sequentially detaching the pump pipe joint and the stop valve, and cleaning concrete in the pipe;
step 4.4, cleaning concrete in the pipe joint of the pump pipe outside the column;
4.5, after the concrete is initially set, removing nuts on the built-in bolts of the built-in reinforcing plates of the columns to separate the pump pipe joints outside the columns from the column bodies;
wherein,
the end plate of the external concrete pump pipe joint is provided with an L-shaped groove, during the concrete jacking, the bolt is fixedly embedded in the transverse groove, after the concrete is jacked to a specified elevation, the end plate is knocked, so that the bolt is transferred to the top of the vertical groove, and the external concrete pump pipe joint and the hole of the column body are completely staggered.
In the traditional concrete jacking construction process, the joint pump pipe is scrapped after being used once, the joint pump pipe is cut, time is consumed, and concrete on the joint surface of the column body is not smooth. According to the invention, the two-stage stop valve is arranged, so that the joint pump pipe can be recycled, and the resource waste is reduced; the pump pipe cutting head does not need to be cut off any more, and the contact surface can be separated by disassembling the bolt and knocking with a steel hammer, so that the construction difficulty is reduced, and the manual input is reduced; the concrete of the joint surface of the column body is formed when the concrete inside and outside the column is separated, and the surface is smoother and more beautiful after the concrete is solidified.
