How to classify it according to the working method of the spiral steel pipe?
The spiral steel pipe irrigation system can be divided into mobile, semi -fixed and fixed.
1. Mobile. In addition to water sources, you can also move pipelines and water supply equipment. Some pumps are fixed and some can also move. The spiral steel pipes are mostly made of thin -film plastic hose or Vilunlon -covered plastic hose. It uses simple and convenient, low cost, flexible use, strong adaptability, and can turn through the ditch to turn. However, the film plastic hose is not durable and easy to break, and the life span is generally only 1-2 years. In the late period of growth of high -straw crops, it was difficult to move hoses between various rows because of the tall crops.
2. Semi -fixed. One of the pipe system is fixed and the other part is moved. Generally, the main pipeline or stem pipe, the branch tube is a fixed burial tube, connected from the water outlet to move the hose to the scene. This form of support is large, with large export spacing, decreased fixed buried pipes, and decreased unit area investment. However, the ground hose on the ground is frequent, the labor intensity is large, and the working conditions are poor.
3. Fixed formula. The pipelines and water distribution facilities at all levels in the low -pressure pipeline irrigation system are buried underground and fixed. The water bolt or water port is directly divided into field grooves, and there is no hose connection. The field canal in the fields is short, the fixed spiral steel pipe density is high, the standard is high, the operation and management are convenient, and the irrigation is uniform, but the one -time investment is relatively large.
How to manage the spiral steel pipe safety?
In response to the problem of exceeding the quality of the pores of the spiral steel pipe panel, the following preventive measures should be taken:
(1) Try to use internal supporting devices as much as possible.
(2) The welding tube group does well in the section of the welded pipe.
(3) Partial correction of copper hammer or copper cushion hammer.
(4) When the error column port deforms smoothly, cutting should be performed.
Safety management of spiral steel pipes:
(1) When using internal supporting equipment, it is necessary to conduct a good inspection of the supporting equipment, compressor equipment, and tube improvement machines before construction. It should be flexibly used according to the operating regulations.
(2) Before the other party uses, check whether the equipment used by the other party is normal: When using it, special personnel must be set up to command operations in accordance with the standard action instructions to avoid accidents.
(3) In the construction, if the pad or pad pad pad bag is used to install the rice shell high pipeline, the cushion height must be strong and firm to prevent the pipeline from being rolled and damaged; Essence
