What should be done before installing the rubber joint?Today, the small series of Shanghai songxia will introduce to you:
The installation of flexible rubber joints underground requires the installation of a buried device, which can better take care of the role of soft rubber joints.According to pipe diameter and pipe before installation type, groove material situation, construction site environment and construction machinery, such as material situation to plan as a whole, the same, should see fit and use transportation type or crawler crane tube, when the ditch beside the road, narrow around trees, utility poles, pipe diameter is small, can be used under the artificial tube.
The lower pipe has centralized lower pipe, decentralized lower pipe and combined hoisting.Before the pipe trench, the trench should be collapsed in soil, stones, rain, oil and snow, etc.The trench or culvert depth, elevation and section size should be checked and meet the preset requirements;The ditch in the stone section should be loose and not less than 300mm thick. The ditch bottom should be free from bump and 50 pieces.
Gully edge group welding is several pipes in the gully side of the ground group welding, the same feel appropriate and the use of wave welding, welding into the pipe and then servants trench.This method is easy to guarantee, easy to operate and high efficiency.The length of the pipe segment is determined by the diameter of the pipe and the way to lower the pipe. It is not allowed to be too long and cause difficulty in moving, or to bend the pipe segment too much and damage the pipe and anticorrosive layer when the pipe segment is below. It is advisable to have a length of 30-40m without the pipe segment.Due to the coal tar coating coating anticorrosive steel pipe is not allowed to roll welding, so, can only put each steel pipe in the groove feel appropriate and the use of fixed welding.After the pipe is installed and welded, the rubber soft joint is installed individually according to the actual environment.
