Problems solved by technology

[0004] In order to solve the above technical problems, this method provides a construction method for pipe laying and threading with chemical fiber thread, the circular traction method and its construction steps, which not only completely eliminate the waste of steel caused by the method of retaining steel wire, but also avoid the corrosion of steel wire blocking the pipe It can further improve the success rate of cable piercing compared with the steel wire method, which can not only significantly reduce the construction strength and difficulty of the early buried pipe, but also reduce the quality dependence of the later threading link on the earlier buried pipe link. It can reduce the negative effects such as friction and damage caused by the operation itself on the pipe wall, so that the project quality is clearly improved while the cost is greatly reduced, and its scale benefit is very huge

Embodiment 1

[0035] Since there are many factors that cannot be grasped in advance in the resistance during operation, and it is very troublesome to re-thread the lead wire, so every step of the operation must be fully grasped and redundant, with safety and reliability as the primary consideration, so as not to cause trouble. On the contrary, the gain outweighs the loss. But in any case, if during the operation of a certain step, it is found that the lead wire of the front stage is overwhelmed, then there is no need to be embarrassed, as long as the front line is pulled out from the other end of the wire tube in the opposite direction, that is, the problem can be rediscovered. Going back to the previous state, and then rearranging the loop reinforcement scheme will definitely solve the problem. In addition, for professional threading constructors, the operation of multiple loops to strengthen the lead wire should use a winding tool or machine such as a roulette to speed up the construction...

example 1

[0036] Example 1 The wiring object is a common buried pipe with a length of 10 meters and a diameter of 16mm in a residence. The primary lead wire in the pipe is a thin nylon wire or a polyester wire with a diameter of 0.18mm. After testing, it is found that its tensile strength is only about 1.0kg. Be prepared to wear a soft phone cord. Suggestion: You can first use high-quality thin nylon wire with a diameter of 0.13mm and a tensile strength of more than 3kg as the secondary lead, and then lead through the nylon wire with a diameter of 2mm or more to try pulling the telephone line.

example 2

[0037] Example 2 The wiring object is a common buried pipe with a length of 5 meters and a diameter of 16mm in a residence. The primary lead wire in the pipe is a nylon wire with a diameter of 0.5mm. After testing, it is found that its tensile strength is greater than 6kg, and it is a soft telephone line to be worn. Suggestion: You can directly pull the telephone line to try it on. If you feel abnormal in the middle, you can pull out the telephone line from the reverse direction to make the problem return to the previous step. Then, increase the strength of the lead wire in the middle to a nylon wire with a diameter of 2mm or more, and then try it on.

Abstract

The invention relates to a construction method for piping and wiring by using chemical fibers, a cyclic traction method and construction steps thereof. Not only is the steel waste phenomenon caused by the steel wire reserving method completely eliminated, but also the situation of blocking a pipeline by a rusty steel wire can be avoided, and the penetrating success rate of cables can also be further increased as compared with the steel wire reserving method. Not only can the construction strength and difficulty during early-stage pipe laying be obviously lowered, but also the quality dependence degree of the later-stage wiring link on the early-stage pipe laying link can be reduced, and the negative actions of friction, damages and the like caused by operation per se on the pipe wall can also be relieved. Therefore, the cost is greatly lowered while the engineering quality is clearly improved, and the economies of scale are huge.

Description

technical field [0001] The invention relates to a pipe laying and threading construction method in building decoration, in particular to a construction method for pipe laying and threading using chemical fiber threads. Background technique [0002] At present, two methods are mainly used to penetrate the cables in the conduit. One is to reserve a steel wire or iron wire in the conduit, and bury the conduit and the steel wire together during the civil construction stage. In the electrical decoration stage, use the reserved steel wire to pull the cable through the conduit. Its disadvantages are: a waste of steel and laborious construction, and the effect is not good. There may be a few years or even longer intervals between buried pipes and cables. Due to cost constraints, the quality of reserved steel wires is generally not high and easy to rust and reduce tensile strength. Therefore, the steel wires reserved in pipes should not be too thin. , usually the diameter of the st...
