Description
Technical Field
[0001] The utility model relates to the technical field of building anti-freezing and swelling structures, particularly to the technical field of anti-freezing and swelling structures for ground beams, and specifically refers to an anti-freezing and swelling structure for ground beams above the frost heave line. Background Technique
[0002] To ensure the firmness and safety of buildings, the foundation needs to be buried in the soil layer to a certain depth. The buried depth of the foundation refers to the distance from the outdoor design ground surface to the bottom surface of the foundation, abbreviated as the buried depth. There are many factors affecting the buried depth of the foundation, mainly including the following five aspects: the influence of the structure; the influence of the magnitude and nature of the load acting on the foundation; the influence of engineering geological and hydrogeological conditions; the influence of frost heave and thaw settlement of the foundation soil; the influence of the buried depth of adjacent building foundations.
[0003] Among them, in the influencing factor of frost heave and thaw settlement of the foundation soil, the concept of the soil layer frost line is crucial. In cold regions, the soil layer will experience freeze-thaw phenomena due to temperature changes. The boundary between frozen soil and unfrozen soil is called the soil layer frost line, also known as the frost heave line, and the depth of the frost line is the freezing depth. The freezing depth of the soil layer depends on the local climate conditions. The lower the temperature and the longer the low-temperature duration, the greater the freezing depth.
[0004] When the buried depth of the foundation is above the soil layer frost line, if the soil layer below the foundation bottom freezes, an upward frost heave force will be generated on the foundation, and in severe cases, the foundation will be arched upward; if the soil layer below the foundation bottom thaws, the frost heave force disappears and the foundation sinks. Over time, cracks and damage will occur to the building.
[0005] Therefore, it is desired to provide an anti-freezing and swelling structure for ground beams above the frost heave line, which can reduce the frost heave damage of the foundation soil to the ground beam in freezing weather. Content of the Utility Model
