Reinforcement project of cement pipe steel socket jacking
After the jacking of the steel socket jacking pipe is completed, the front wall ends of the concrete structures in the two sections of the steel jacking pipe shall be cut out to reveal the wall reinforcement, and a boss or stepping platform shall be chiseled around the center of the wall.
When strengthening the top port of the steel pipe jacking pipe, you should first measure the pay-off line and check the corresponding materials in accordance with the relevant documents. At the same time, save the original measurement materials to ensure that the measurement materials are complete when the project is completed
What are the insights of the top reinforcement work of the cement pipe steel socket top pipe?
The steel socket jacking professional explained the following analysis with us:
First, adhere to the measurement and review guidelines. In order to ensure the smooth progress of the project, the steel pipe jacking pit shall be installed on the ground to avoid high-voltage lines, telephone lines, power lines and other electrical wires. It shall be provided with isolation and eye-catching signs on the road. Outstanding lighting and Remarkable logotype.
Second, the measuring device is installed after other equipment. The steel socket jacking pipe, especially the spirit level and rangefinder, should not interfere with other equipment, and should not be moved by the force of the jacking pipe. The laser guide should be placed in the same position as the center of the pipeline jacking direction, and accurately guide the front of the pipe at any time. The shallow socket-buried excavation was used for the steel jacking pipe jacking operation to do the reverse construction.
Third, in the working pit made of sprayed concrete, the back wall is cast as a whole with reinforced concrete, the width is equal to the net size of the working pit, and the plane of the back wall must be vertical. When placing the steel jack on the pipe jacking foundation pit guide, its front end should be as close to the opening as possible, and the left and right sides can be supported by channel steel to ensure a smooth road.
We remind you that after the reinforcement of the steel socket jacking pipe is completed, the front wall ends of the concrete structures in the two sections of the steel socket jacking pipe should be removed to reveal the wall reinforcement, and a boss or step should be cut around the center of the wall. station. If you find that there are expanded rubber strips and welded steel bars, you need to pour the concrete first, and then waterproof the outer wall after molding.
