安装橡胶接头之前，应该做好哪方面的准备工作？今天上海松夏的小编就为大家介绍一下：
What should be done before installing the rubber joint?Today, the small series of Shanghai songxia will introduce to you:
在地下安装可曲挠橡胶接头需求加装地埋装置，可以更好的起到尽量照顾橡胶软联接的作用。管道安装前可根据管道直径及种类、沟槽物质情形、动工场地周围环境与动工机具等物质情形进行统筹，一样来说，应觉得合适而运用交通工具式或履带式吊车下管，当沟旁道路狭窄，周围树木，电线杆较多，管径较小时，可用人工下管。
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.
下管方式有集中下管、分散下管、组合吊装。管道下沟前，应将管沟内塌方土、石块、雨水、油污和积雪等.干净;应检查沟或涵洞深度、标高和断面尺寸，并应符合预设要求;石方工程段管沟，散松软和垫厚度不能低于300mm，沟底应没有凹凸、五十块。
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.
沟边组队焊接就是将几根管道在沟旁的地面上组队焊接，一样觉得合适而运用波动焊接，焊成管段再仆人地沟。此方法易担保，操作方便，出产效率高。管段长度由管径大小及下管方法而定，不可以过长而造成移动困难，也不可以下管时管段弯曲过大而损伤管道与防腐层，没管段以30~40m长为宜。由于煤木焦油滋漆遮盖层防腐的钢管不准许滚动焊接，所以，只能将每根钢管放在沟内觉得合适而运用固定焊。在管道钢管进行安装焊接后，橡胶软连接根据实际环境的不同进行单个安装。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.
