Description

Technical Field

[0001] The utility model relates to the field of GIS installation, in particular to a track foundation device for a GIS installation mobile workshop that does not need to be demolished. Background Art

[0002] Gas-insulated switchgear (GIS) is widely used in high-voltage, extra-high-voltage and ultra-high-voltage fields. Compared with conventional open substations, GIS has the advantages of compact structure, small floor area, high reliability, flexible configuration, convenient installation, strong safety, strong environmental adaptability, and very little maintenance work. However, GIS also has inherent defects such as complex installation technology, great influence of the environment on the installation quality, and difficult maintenance. In some areas, due to factors such as strong wind and sand, complex and changeable weather, and complex geological conditions, the installation quality and construction progress of GIS installations will be seriously affected, and problems such as the inability of the installed GIS equipment to pass the withstand voltage and partial discharge tests often occur. In response to this, mobile workshops are considered to be set up during GIS installation in some areas to ensure the installation quality and progress of GIS.

[0003] Since the overall layout of GIS is compact, and there are a large number of GIS piers, cable trenches, switch control cabinets, terminal boxes, etc. arranged therein. If the mobile workshop is used for enclosed installation, technically, mobile workshop tracks need to be set on both longitudinal sides of GSI, and there should be no obstacles in the surrounding area of the tracks to ensure the smooth operation of the mobile workshop. This often leads to the situation that during on-site implementation, the track foundation needs to be fabricated first. After the GIS installation is completed, the track foundation needs to be demolished, and then the steel bars need to be re-tied, formwork needs to be supported, and the foundations of GIS piers, cable trenches, switch control cabinets, terminal boxes, etc. need to be poured. Engineering practice shows that such a method is not only cumbersome and difficult to construct, but also costly, has a long construction period, is not beautiful, and has a great impact on project construction.

[0004] In view of this, a new construction plan needs to be proposed for the workshop track foundation to solve the many disadvantages brought by demolition and reconstruction in the prior art. Summary of the Utility Model

[0005] The problem to be solved is to design a construction plan for the track foundation of a GIS installation workshop to avoid the many disadvantages in the prior art.

[0006] To achieve the above object, the utility model provides the following technical solution: A track foundation device for a GIS installation mobile workshop that does not need to be demolished, including a plurality of combined connection devices. The length direction of the combined connection device includes a track base, and a cable trench one and a cable trench two are respectively arranged on both sides of the track base. A number of culverts are arranged at intervals in the combined connection device, and all the culverts connect the cable trench one and the cable trench two. A control cabinet foundation is arranged on one side of the cable trench two, and a cable trench three and a cable trench four are arranged around the control cabinet foundation. A terminal box foundation is arranged at the bottom of the combined connection device, and the center line above the combined connection device is the track center line, and track embedded parts are arranged along the track center line.

[0007] Preferably, the widths of the cable trench two, the cable trench three, and the cable trench four are all smaller than the width of the culvert.

[0008] Preferably, there are reserved inserted bars on both the control cabinet foundation and the upper end of the terminal box foundation.

[0009] Preferably, the track embedded parts include a plurality of bolts arranged at intervals.

[0010] Preferably, cable support brackets are arranged in the cable trench one, the cable trench two, the cable trench three, the cable trench four, and the culvert.

[0011] Preferably, a drainage ditch is arranged at the bottom of the cable trench one.

[0012] Compared with the prior art, the utility model provides a track foundation device for a GIS installation mobile workshop that does not need to be demolished, and has the following beneficial effects: By systematically sorting out the spatial layout of various structures in the GIS area around the mobile workshop track and combining the construction sequence on site, the utility model innovatively proposes a track foundation device for a GIS installation mobile workshop that does not need to be demolished. This scheme has been applied in the project, with simple construction, short construction period, low cost, beautiful quality, and good benefits.

Detailed implementation mode

[0016] The technical solutions in the embodiments of the present utility model will be described below with reference to the accompanying drawings in the embodiments of the present utility model:

[0017] As shown in the figure, a track foundation device for a GIS installation mobile workshop that does not need to be demolished includes a plurality of combined connection devices 1. The length direction of the combined connection device 1 is the traveling direction of the GIS installation workshop. A cable trench 1 and a cable trench 2 are arranged in parallel with the combined connection device 1. Between the cable trench 1 and the cable trench 2 is the track base 11. Three culverts 4 are arranged at intervals in the combined connection device 1. All three culverts 4 connect the cable trench 1 and the cable trench 2. The culverts 4 are located below the track base 11. A control cabinet foundation 5 is arranged on one side of the cable trench 2. The highest point of the control cabinet foundation 5 does not exceed the track base 11, so as not to affect the operation of the workshop; a cable trench 3 and a cable trench 4 are arranged around the control cabinet foundation 5. A terminal box foundation 6 is arranged at the bottom of the combined connection device 1. The highest point of the terminal box foundation 6 does not exceed the track base 11, so as not to hinder the progress of the workshop; openings are left at the positions of the combined connection device 1 corresponding to the terminal box foundation 6 and the control cabinet foundation 5. The openings are mainly used for the cable leading down of the control cabinet, the terminal box or the GIS cable trough box; the center line above the track base 11 is the track center line 12. Track embedded parts 7 are arranged along the center line. In some application scenarios, the GIS has piers for supporting the GIS. The corresponding combined connection device 1 reserves the insertion bars for the GIS pier foundation. The insertion bars for the GIS pier foundation are not poured first. After the GIS installation is completed, the corresponding foundation is poured, which is safe and reliable.

[0018] In a preferred embodiment, the widths of the cable trench 2, the cable trench 3 and the cable trench 4 are all smaller than the width of the culvert 4. Since the culvert 4 collects the cables of each route, the space of the culvert should be larger, but it cannot be higher than the track base 11. Therefore, the culvert 4 is designed to be wider. The width of the culvert 4 is greater than the width of any one of the cable trench 2, the cable trench 3 and the cable trench 4. The cross-sectional size of the corresponding culvert 4 can be flexibly set according to different sites. Since there are many cables in the substation, in order to arrange the cables neatly and facilitate the search for specific cables, cable supports 8 are arranged in the cable trench 1, the cable trench 2, the cable trench 3, the cable trench 4 and the culvert 4. The cables are neatly arranged on the cable supports 8; a drainage ditch 9 is arranged at the bottom of the cable trench 1, and the bottom of the cable trench 1 is lower than the bottoms of other cable trenches, so that the water is collected in the drainage ditch 9 and discharged centrally.

[0019] There are reserved inserted steel bars on both the foundation 5 of the control cabinet assembly and the upper end of the terminal box foundation 6. The inserted steel bars are not concreted first. After the GIS installation is completed, the foundation 5 of the control cabinet assembly and the terminal box foundation 6 are then concreted. This is safe and reliable and does not require secondary rework. The lengths of the inserted steel bars on the foundation 5 of the control cabinet assembly and the terminal box foundation 6 meet the final required lengths. The parts higher than the track base 11 are bent before the track is removed, so that it will not affect the operation of the plant and there is no need for secondary demolition and reconstruction. The track embedded parts 7 include a plurality of bolts arranged at intervals, and the bolts are used to fix the laid plant track.

[0020] Through systematically sorting out the spatial layout of various structures in the GIS area around the mobile plant track and combining with the construction sequence on site, the utility model innovatively proposes a GIS installation mobile plant track foundation device that does not require demolition. The device is composed of a combination of multiple reinforced concrete culverts 4, and according to the actual needs on site, openings, track embedded parts 7, and reserved inserted steel bars for the GIS pier foundation, the foundation 5 of the control cabinet assembly, and the terminal box foundation 6 are set at relevant positions above the combined connection device 1, solving the problem of demolition and reconstruction proposed in the background technology.

[0021] In actual projects, different numbers of culverts can be set according to the actual situation on site, and openings, embedded parts, and inserted steel bars can be set as required, not limited to the following drawing examples. Any modifications and equivalent replacements within the spirit and principle of the utility model should be considered within the scope of the utility model.
