Description

Construction method for changing electric U-shaped groove into calandria
Technical Field
The invention relates to the technical field of electric power engineering, in particular to a construction method for changing an electric power U-shaped groove into a calandria.
Background
With the rapid development of cities, the original power engineering needs to be modified and upgraded. Urban road reconstruction and upgrade projects are developed in various places in recent years, existing municipal roads are widened to cause that a plurality of electric U-shaped grooves which are originally arranged below sidewalks are changed to be arranged below motor vehicle lanes, or due to planning and adjusting of level intersections of newly-built roads and existing roads, the existing road electric power projects are not considered to be reinforced by electric drainage pipes, so that the original electric power projects are difficult to reconstruct and upgrade, and if the existing electric power projects are directly migrated and modified, the problems of high cost, long construction period, large social influence and the like exist.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention aims to provide a construction method for changing an electric U-shaped groove into a calandria, which is used for reducing the influence of the reconstruction project on the surrounding environment and traffic, improving the construction efficiency and shortening the construction period.
The invention is realized by the following technical scheme: a construction method for changing an electric U-shaped groove into a calandria is characterized in that an electrified original cable is subjected to insulation treatment, the existing electric U-shaped groove and surrounding earthwork are broken to form a new groove, and the original cable and a plurality of electric calandria serving as reserved pipelines are installed in the new groove.
Further, in order to better implement the invention, the insulation treatment comprises coating the outer side of the original cable with an insulation material.
Further, in order to better implement the invention, the insulating material adopts a UPVC pipe.
Further, in order to better implement the invention, the UPVC pipe is divided into two halves by a plane passing through the axis.
Furthermore, in order to better realize the invention, after the UPVC pipe is coated on the outer side of the original cable, an insulating tape is wound on the outer side of the UPVC pipe.
Further, in order to better realize the invention, the concrete formwork is installed and concrete is poured after the original cable and the reserved pipeline are installed in the power grid.
Further, in order to better realize the invention, the original cable and the reserved pipeline are fixed by a pipe frame during installation.
The beneficial effect that this scheme obtained is: this scheme reforms transform on the basis in original electric power U type groove, is under construction or extension in original structure, can shorten construction cycle, reduces the area that the construction site occupied, reduces the influence that the construction brought ambient environment, traffic, avoids changing the problem that exists.

Detailed Description
The present invention will be described in further detail with reference to examples, but the embodiments of the present invention are not limited thereto.
In the embodiment, the construction method for changing the power U-shaped groove into the calandria is to perform insulation treatment on the electrified original cable 1, break the existing power U-shaped groove and the surrounding earthwork to form a new groove, and install the original cable 1 and a plurality of power calandria 3 serving as reserved pipelines in the new groove.
This scheme reforms transform on the basis in original electric power U type groove, is under construction or extension in original structure, can shorten construction cycle, reduces the area that the construction site occupied, reduces the influence that the construction brought ambient environment, traffic, avoids changing the problem that leads to.
In this embodiment, the insulation treatment includes coating the outer side of the original cable 1 with an insulation material. The insulating material is coated on the outer side of the original cable 1, so that the risk of electric leakage is avoided, and the safety of workers is guaranteed.
In this embodiment, the insulating material is a UPVC pipe 2. The UPVC has the advantages of strong corrosion resistance, high mechanical strength, light weight, good water tightness and the like, and the UPVC pipe 2 is adopted as an insulating material to protect the original cable 1, so that the risk of electric leakage caused by the fact that the original cable 1 is deformed by pressure, damaged by pressure, permeated and the like can be avoided, and the influence on the electrification of the original cable 1 is avoided.
In this embodiment, the UPVC pipe 2 is divided into two halves by a plane passing through the axis, so that the UPVC pipe 2 is conveniently installed on the original cable 1, the UPVC pipe 2 is wrapped on the outer side of the original cable 1, and then the insulating tape is wound on the outer side of the UPVC pipe 2. The UPVC pipe 2 is kept stable by using the insulating adhesive tape, and the gap between the two half UPVC pipes 2 is repaired to prevent impurities from entering the UPVC pipe 2.
In this embodiment, after the original cable 1 and the reserved pipe are installed in the power grid 3, a concrete formwork is installed and concrete 4 is poured. The power calandria 3 and the original cable 1 are protected by pouring the concrete 4, the power calandria 3 and the UPVC pipe 2 can protect the internal cables and other structures from bearing pressure, and the cables are prevented from being crushed.
The concrete 4 is formed by pouring C25 concrete, and a concrete cushion 5 formed by pouring C20 concrete is arranged below the concrete 4
Original cable 1 and reservation pipeline utilize the pipe support fixed when the installation. Utilize the pipe support to fix original cable 1 and reservation pipeline respectively, can make original cable 1 and reservation pipeline keep in appointed position, control original cable 1 and reservation pipeline, reservation pipeline and the interval of reservation pipeline to control concrete structure thickness everywhere, make concrete structure can satisfy bearing capacity's requirement, avoid making concrete structure damage under the pressure of vehicle.
In this embodiment, other undescribed contents are the same as those in the above embodiment, and thus are not described again.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all simple modifications and equivalent variations of the above embodiments according to the technical spirit of the present invention are included in the scope of the present invention.
