Embodiment

[0025] Based on the trusteeship construction process in the laying of cable pipes, the following steps are included:

[0026] Surveying and setting out: Plane control and setting out: According to the existing sidelines, use the control points provided by the surveyor to measure the positioning points of the project, and set up a pile every 3 meters along the center line of the pipe on the ground with a total station before construction , and spread the white ash line along the center line of the pipe and measure the pile elevation, and calculate the relationship between the pile elevation and the design pipe flow surface;

[0027] Elevation control: Measure the elevation control points on the construction site according to the benchmark provided by the surveyor. The elevation control adopts the method of measuring the elevation of the instrument twice before and after the same distance to maintain accuracy. In order to ensure the correctness of the design direction and positio...

Abstract

The invention discloses a paired cable duct bank laying-based support pipe construction process, which comprises the following steps of measuring and setting out, excavating a foundation pit, drilling with a drill rig, pulling back a drilling hole, welding a pipeline, pulling back a laying pipeline and backfilling the foundation pit. The process can be used for effectively constructing a support pipe, is short in construction time and good in construction time and solves the problems that the pipeline is cracked or the line can not be constructed frequently caused by the existing construction method.

Description

technical field [0001] The invention relates to a construction process, in particular to a trusteeship construction process based on cable pipe laying, and belongs to the field of electric power construction. Background technique [0002] Electricity is an energy source powered by electrical energy. Invented in the 1870s, the invention and application of electricity set off the second industrialization climax. It has become one of the three scientific and technological revolutions in the world since the 18th century in human history. Since then, technology has changed people's lives. Even in today's Internet age we still have a growing demand for electricity, as we have invented more products that use electricity, such as computers and home appliances. It is undeniable that the continuous emergence of new technologies has made electricity a necessity for people. The large-scale power system that appeared in the 20th century is one of the most important achievements in the...
