对管道进行沟槽管件卡箍连接施工工艺要点概述Outline of construction technology for pipe hoop connection of trench pipe
经济发展，各地的管道连接大范围的进行着，对于管道连接来说，沟槽式卡箍连接为*********、最经济的一类连接工艺，在多个用途的工程管道连接中被使用，沟槽管件连接与传统的管道焊接、法兰连接与螺纹连接的模式，是一种快速、可靠、简易、环保、经济实用的连接方式。
管道沟槽式卡箍连接的优点，可以概括为下列几点。
1、施工场地简单、占地少，施工不受气候影响和限制。改变了传统工艺需要很大的加工场地，适宜工厂化预制。
2、便于水平及垂直运输，特别是改造工程可不受原建筑环境的限制，大大提高了管道的运输效率。如在长管道运输不便的条件下，可按楼层高度定制管长分段运输。
3、与管道采用焊接连接方式相比，免除了先焊接后再送去镀锌的工序，可先镀锌后预制；并且管道只需通过长度定位即可预制成型，减少了相关工作的制约，有利于施工工期的合理安排。
4、管道用沟槽式卡箍连接，改变了传统施工技术型工人的需求，无需特种作业上岗证，一般工人就可操作，操作简单、方便、快捷。
5、施工质量可靠，在规定工作压力下，压力越大密封性能越好。管道安装可根据需要任意调整角度和方向，避免了传统法兰连接因预制偏差而产生不可弥补的缺陷。
6、对施工环境要求不高，特别是在相对狭小的工作空间及场所施工，更是发挥了其优势。便于用户的使用维护，便于使用中管路的改造和延伸工作。
7、对大管径管道安装更能体现其简易、方便和实用的特点。
With economic development, pipeline connections are carried out in a large range. For pipe connections, grooved clamp is connected to the most advanced and most economical connection process. It is used in multi purpose engineering pipe connections. Groove pipe fittings are connected with traditional pipe welding, flan connection and thread connection. A fast, reliable, simple, environmentally friendly, economical and practical way of connecting.
The advantages of pipe trench hoop connection can be summarized as follows.
1. The construction site is simple, the land occupation is little, and the construction is not affected by the climate. Changing the traditional process requires a large processing site, suitable for factory prefabrication.
2. It is convenient for horizontal and vertical transportation, especially the renovation project can not be restricted by the original building environment, which greatly improves the efficiency of pipeline transportation. For example, under the condition of inconvenient transportation of long pipelines, the pipeline length can be customized according to the height of floors.
3. Compared with the welding connection mode of the pipe, the galvanizing process is removed after the first welding, and the galvanizing process can be prefabricated first; and the pipe can be prefabricated by the length positioning, which reduces the restriction of the related work and is beneficial to the reasonable arrangement of the construction period.
4. The trench type clamps connected to the pipe have changed the demand of the traditional construction technology workers, without the special operation certificate. The general workers can operate, and the operation is simple, convenient and quick.
5, the construction quality is reliable, under the specified working pressure, the greater the pressure, the better the sealing performance. Pipe installation can adjust the angle and direction arbitrarily according to need, avoiding the irreparable defect of traditional flange connection due to prefabrication deviation.
6, the construction environment is not very high, especially in relatively narrow workspace and site construction, but also to play its advantages. It is convenient for users to use and maintain and facilitate the transformation and extension of pipelines in use.
7. Installation of large diameter pipe can be more simple, convenient and practical.
