[0003]目前，箱式变电站的安装面临雨水渗漏、地基沉降及绝缘油泄漏污染环境的挑战，亟需一种能够综合解决上述问题的新型基础结构
[0015]针对目前箱式变电站存在的问题，发明人设计了一种用于箱式变电站的基础结构，主要包括预制混凝土底座和分离存储箱，预制混凝土底座的外围由内向外分别设置污水收集渠、碎石排水层；碎石排水层外围由矩形套板包围，碎石排水层的底部设置碎石疏水通道；分离存储箱设置在预制混凝土底座外侧，并通过污水管道连接污水收集渠。应用本实用新型作为箱式变电站的安装基础，污水收集渠可以收集含有油污的雨水，碎石排水层和碎石疏水通道可以在降水时将水分快速引流至地下，避免雨水聚集在预制混凝土底座周围导致疏松土壤地基变形，保证了箱式变压器的稳定使用。此外，分离存储箱内分隔为储油池、泵房和分离池，可将收集的油水混合物进行分离，并将绝缘油分离出来单独存储在储油池内，方便维护人员集中处理，避免油污泄漏对于周围环境产生影响。

Abstract
Claims
1. A foundation structure for a box-type substation, characterized in that It mainly includes a precast concrete base and a separate storage box. The precast concrete base is surrounded by a sewage collection channel and a gravel drainage layer from the inside out. The gravel drainage layer is surrounded by a rectangular sleeve plate, and a gravel drainage channel is set at the bottom of the gravel drainage layer. The separate storage box is set outside the precast concrete base and is connected to the sewage collection channel through a sewage pipe.
2. A foundation structure for a box-type substation according to claim 1, characterized in that: The top side of the sewage collection channel is covered with a grating plate.
3. The foundation structure for a box-type substation according to claim 1, characterized in that: Both the gravel drainage layer and the gravel drainage channel are laid with gravel with a particle size of 5-8 cm. The depth of the rectangular sleeve and the thickness of the gravel drainage layer are 30 to 40 cm.
4. The foundation structure for a box-type substation according to claim 1, characterized in that: The separation storage tank is equipped with two partitions, which divide the separation storage tank into an oil storage tank, a pump room, and a separation tank. The pump room is located between the oil storage tank and the separation tank.
5. The foundation structure for a box-type substation according to claim 4, characterized in that: A drainage pump is fixedly installed on the bottom side of the separation tank, and a drainage pipe is fixedly installed at the output end of the drainage pump, extending to the outside of the separation storage tank.
6. The foundation structure for a box-type substation according to claim 4, characterized in that: The pump room is equipped with an oil pump, the input end of which is connected to the separation tank pipeline and the output end of which is connected to the oil storage tank pipeline.
7. A foundation structure for a box-type substation according to claim 6, characterized in that: A sliding rod is fixedly installed on the bottom side of the separation tank, and a float plate is slidably installed on the sliding rod. The pipe connecting the input end of the oil pump is set on the float plate.
8. A foundation structure for a box-type substation according to claim 7, characterized in that: A protective cabin is fixedly installed on the top side of the precast concrete base, and a box-type transformer is arranged inside the protective cabin.
9. A foundation structure for a box-type substation according to claim 8, characterized in that: The precast concrete base has a water collection channel on the bottom side of the box-type transformer, and a sewage pump is installed in the water collection channel.
