Problems solved by technology

Its disadvantages are: 1) The outer diameter range of the optical cable suitable for blowing is only: φ10-32mm; the corresponding inner diameter range of the silicon tube is: φ25-51mm
2) It is not possible to construct pipelines that are not resistant to high-pressure gas
3) The ratio between the pipe and the cable / micropipe cannot be small

Embodiment Construction

[0028] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings: the present embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and processes are provided, but the protection scope of the present invention is not limited to the following implementations example.

[0029] In FIG. 1 , the guide sealing structure 6 and the optical cable 3 are tightly fixed together by bolts. In Fig. 1 and Fig. 2, the pump for entering water is pump 1, and the pump for water recovery is pump 2. In Fig. 2, filter device 9 is used to filter impurities such as soil to protect the pump. The guide sealing structure 6 has a sealing ring 8 inside and a nylon structure on the outside, which just fits with the pipeline and plays the role of sealing and guiding. The water outlet of the water pump 1 is connected to the water inlet of the sealing structure 5 through the pr...

Abstract

A water-installing optical cable installation construction method for construction technique fields pushes the optical cable into a pipe by a mechanical optical cable thruster. Simultaneity, the press-added current which forms a drag force on the surface of the optical cable is inputted into the pipe through a water intake apparatus by using a water press. The press of the water acts on a steering seal structure connected with the optical cable head to form a forward force. The optical cable is under a floating state by the flotage of the water. The AC servo motor and the water press are controlled by a controllor to install the optical cable. The invention has the advantages of: low energy consumption, high speed of installation, applicability of the complicated pipe path, achievement of safe and long-distance optical cable installation, samll volume of the whole equipment and applicability of the field work.

Description

technical field [0001] The invention relates to a method in the technical field of construction engineering, in particular to a water-laying optical cable laying construction method. Background technique [0002] In urban construction, the laying of optical cables is a very important part, which is related to the smooth communication of the city. The rigidity of the optical cable itself and the maximum temperature it can withstand put forward high requirements for laying. Practice has proved that failure accidents of optical cables are often caused by damage during laying, resulting in huge losses. Traditional optical cable laying methods mainly include the following: 1. Mechanical traction method; 2. Directly buried optical cable method; 3. Aerial optical cable; 4. Underwater optical cable; 5. Pipeline optical cable. These methods use the mechanical traction method to lay the optical cable, which will cause many problems during the laying process. For example: in method 1...
