Detailed description of the invention
The following stated is better embodiment of the present utility model, does not therefore limit protection domain of the present utility model.
The novel box type transformer foundation structure the utility model proposes below with reference to Fig. 2-4 pair is described.
As shown in the figure, the length of box type transformer body 1 is a, and wide is b, and height is c, according to an embodiment, and a≤3000mm,B≤3000mm, according to other embodiment, need increase by a row as institute below every 3000mm if a, b value exceed 3000mmThe bearing-type pile body of stating, c value is determined according to different box type transformer models.
Described foundation structure comprises the bearing-type coupling beam 3 directly contacting with box type transformer body 1, and described bearing-type coupling beam 3 isDirectly bear the load that the transmission of box type transformer body comes and pass to the beam of bearing-type pile body. According to an embodiment, instituteState bearing-type coupling beam 3 and can be reinforced concrete cast-in-situ beam, armored concrete or shaped steel precast beam etc. According to an embodiment, instituteStating base steel plate and the bearing-type coupling beam 3 of box type transformer body 1 can adopt in welded or bolted way.
Described foundation structure comprises the sidewall 4 of Non-carrying type maintenance casing, and maintenance casing is that box type transformer body 1 below is reservedFor the isolation box type space of installation and maintenance. According to an embodiment, described sidewall 4 can be armored concrete, fired brickOr other masonry structure. As shown in Figure 2,3, described sidewall 4 part sides of resting on the ground, a part is positioned at below ground,Wherein d is the height of the sidewall part above ground level of maintenance casing, and e is the height of maintenance casing lower than above ground portion.
Described foundation structure also comprises the ground 5 of the Non-carrying type maintenance casing of sidewall 4 belows that are positioned at Non-carrying type maintenance casing,Wherein, Non-carrying type maintenance casing has four sidewalls, ground 5 structures of the Non-carrying type maintenance casing of these four sidewalls and belowBecome the rectangular structure of a hollow. According to an embodiment, the ground 5 of described Non-carrying type maintenance casing is from top to bottom distinguishedFor surface layer, basic unit and former soil layer. Wherein, f is the thickness on the ground 5 of Non-carrying type maintenance casing, and h is that basis is maximum embeddingThe degree of depth.
