The utility model discloses an anti frost expansion prefabricated inclined base for the structural support of a substation, which includes a support body, wherein the support body is a pyramid platform, and the included angle between the side surface and the bottom surface of the support body is 76 \u00b0 - 90 \u00b0; the support body is a hollow structure, and a support column is arranged in the support body; a number of through holes are arranged on the support body around the support column, and a wave spring is arranged in the through hole; the support body The included angle between the side and the bottom of the support is 80.5 \u00b0. When the soil layer is frozen, the side of the support is inclined, so the force on the side of the support will be decomposed into horizontal and vertical downward pressure. Because the sum of the areas on the side of the whole support is far greater than the area on the bottom, the sum of the vertical downward component forces on the side will also be greater than that on the bottom Force, so as to avoid the up and down movement of the support body. In addition, the component forces in the horizontal direction between the sides are also offset each other, so as to avoid the movement of the support body in the horizontal direction. Therefore, for the support body itself, the resultant force is zero.
【技术实现步骤摘要】
一种用于变电站构支架的抗冻胀预制斜面基础
本技术涉及一种预制基础,尤其是一种用于变电站构支架的抗冻胀预制斜面基础。
技术介绍
目前,为了加快变电站内建筑物的建设,因此在很多地区都采用预制基础,然而在北方寒冷地区,当土中含有足够的水份,遇到使水分子结冰的气象条件时,土中的水分子就结为冰晶体,进而产生冻胀力和冻切力,使建构筑物基础产生竖向或横向变形,这种现象在冻胀期间可能不致引起破坏,但在春季融化期,由于地基土中冰晶体的融解,又成为地基土或垫层承载力降低的原因,造成上部结构的不均匀沉降,从而产生破坏,或影响使用,越是高寒地区这种现象越严重,因而影响安全生产,降低其使用寿命。
技术实现思路
本技术的技术任务是针对以上现有技术的不足,而提供一种用于变电站构支架的抗冻胀预制斜面基础。本技术解决其技术问题所采用的技术方案是:一种用于变电站构支架的抗冻胀预制斜面基础,包括支撑体,其中所述支撑体呈棱锥台,所述支撑体的侧面与底面之间的夹角为76°~90°。进一步改进:所述支撑体呈中空结构,所述支撑体是由四个侧面、一个底面和一个顶面组成,在所述支撑体内设有支撑柱。进一步改进:在所述支撑体内设有支撑柱,在所述支撑柱周围的支撑体上设有若干通孔,在所述通孔内设有波形弹簧。进一步改进:所述支撑体的侧面与底面之间的夹角为80.5°。本技术的优点:当土层冻结时,由于支撑体的侧面呈斜面设计,因此支撑体侧面受到的力将分解成水平方向和竖直向下的压力,由于整个支撑体侧面的面积之和远大于底面的面积,因此侧面所受到的竖直向下的分力之和也会大于底面受到的支撑力,从而避免了支撑体能上下移动的情况,另外各侧面之间 ...
