安裝橡膠接頭之前，應(yīng)該做好哪方面的準(zhǔn)備工作？今天上海松夏的小編就為大家介紹一下：
What should be done before installing the rubber joint?Today, the small series of Shanghai songxia will introduce to you:
在地下安裝可曲撓橡膠接頭需求加裝地埋裝置，可以更好的起到盡量照顧橡膠軟聯(lián)接的作用。管道安裝前可根據(jù)管道直徑及種類、溝槽物質(zhì)情形、動(dòng)工場(chǎng)地周圍環(huán)境與動(dòng)工機(jī)具等物質(zhì)情形進(jìn)行統(tǒng)籌，一樣來(lái)說(shuō)，應(yīng)覺得合適而運(yùn)用交通工具式或履帶式吊車下管，當(dāng)溝旁道路狹窄，周圍樹木，電線桿較多，管徑較小時(shí)，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、組合吊裝。管道下溝前，應(yīng)將管溝內(nèi)塌方土、石塊、雨水、油污和積雪等.干凈;應(yīng)檢查溝或涵洞深度、標(biāo)高和斷面尺寸，并應(yīng)符合預(yù)設(shè)要求;石方工程段管溝，散松軟和墊厚度不能低于300mm，溝底應(yīng)沒有凹凸、五十塊。
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.
溝邊組隊(duì)焊接就是將幾根管道在溝旁的地面上組隊(duì)焊接，一樣覺得合適而運(yùn)用波動(dòng)焊接，焊成管段再仆人地溝。此方法易擔(dān)保，操作方便，出產(chǎn)效率高。管段長(zhǎng)度由管徑大小及下管方法而定，不可以過長(zhǎng)而造成移動(dòng)困難，也不可以下管時(shí)管段彎曲過大而損傷管道與防腐層，沒管段以30~40m長(zhǎng)為宜。由于煤木焦油滋漆遮蓋層防腐的鋼管不準(zhǔn)許滾動(dòng)焊接，所以，只能將每根鋼管放在溝內(nèi)覺得合適而運(yùn)用固定焊。在管道鋼管進(jìn)行安裝焊接后，橡膠軟連接根據(jù)實(shí)際環(huán)境的不同進(jìn)行單個(gè)安裝。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.
