Embodiment 1

[0088] A construction method dedicated to power pipe jacking, comprising the following steps:

[0089] Construction of working pit: According to the characteristics of this project and combined with the actual situation, the rainwater pipeline and sewage pipeline are combined into one

[0090] A working pit is excavated. The width of the working pit is 12000mm, the length is 6000mm, and the depth is 4000mm. The diameter of the jacking pipe is 1000mm. In the working pit made of sprayed concrete, the back wall is integrally poured with reinforced concrete, and the width is equal to the net size of the working pit. The plane of the back wall must be perpendicular to the horizontal plane. The side can be supported by channel steel. Because the pipe is very heavy, the elevation of the guide rail is 20-30mm higher than the required elevation. After compression and sinking, it is the same as the design height. The installation of the measuring instrument is carried out after the inst...

Abstract

The invention discloses a special construction method by utilizing an electricity jacking pipe. The method comprises the following steps of working pit construction, hoisting equipment installation, rail installation, jacking, cave opening reinforcement and grouting and backfill. According to the construction method, the construction process by utilizing the jacking pipe is adopted, the influence on a road can be reduced as much as possible, and it can be guaranteed that the road is unobstructed. As the influence on an ambient environment is small, construction can be carried out day and night. Besides, continuous construction can be carried out, and construction quality is stable.

Description

technical field [0001] The invention relates to a construction method, in particular to a construction method dedicated to electric power pipe jacking, which 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 t...
