Descripción del producto

一、产品介绍

 

注浆塞也叫注浆塞、注水孔封闭器、膨胀管。根据*0世纪*0年代后期对外注浆施工的实际情况,经过大量试验,****是一种先进的多功能深孔注浆堵头机。* * * 用于水力压裂、注浆和煤矿、铁矿瓦斯抽采。

 

二、用法

 

1、连接所有管路系统,拧紧所有螺纹,连接气源(或液压泵),将注浆塞置于孔口(或一端封闭钢管内)试压,检查接头是否漏水,并将其放入孔中备用。

 

2. Open the pressure reducing valve of the gas cylinder or the water pressure pump to allow the grouting plug to expand slowly. Note that the inflation pressure must be greater than 2/3 of the grouting pressure. Grouting can be started when the predetermined pressure is reached.

 

3. At the beginning of grouting, when there is a large amount of grout coming out of the grout return port, slowly pressurize it to the predetermined grouting pressure by several times, otherwise it is easy to form a large differential pressure. During grouting, the pressure on the pressure gauge of the pressure reducing valve of the gas cylinder shall be checked frequently. If it is reduced, it shall be supplemented immediately.

 

4. When the grouting time is long, it is necessary to check whether there is grout channeling, blocking and returning. If there is, stop grouting, release the pressure, and loosen the air plug up and down to prevent it from being consolidated and difficult to take out.

 

5. At the end of grouting, the grouting pressure must be released first, and then the inflation pressure. Do not release the inflation pressure first to prevent the grouting plug from shooting out and causing accidents.

 

6. After grouting, just put the grouting plug into the closed steel pipe at one end, inflate about 0.5Mpa, and then carry out circulating flushing.

 

7. After the grout plug is taken out, connect the water pipe with the grout inlet pipe and the grout return pipe for flushing.

 

8. When multiple holes are grouted together, all pipelines must be arranged in parallel and shall not be twisted together to prevent one hole from affecting other holes.

 

9. After a long time of use, the lower end of the grouting plug shall be disassembled for cleaning and greased.

 

*0. When long cracks or relatively broken are found during drilling, grout channeling, plugging and grout return may occur, and another air pipe shall be put to the upper end of the grouting plug. If grout channeling, plugging and grout return occur, high pressure air shall be used to flush it to prevent jamming.
