Anti-seismic foundation structure for refuges in soft geological environments such as sand beaches

Abstract

The invention discloses an anti-seismic foundation structure for refuges in soft geological environments such as sand beaches. The anti-seismic foundation structure comprises a ground surface, a connecting steel plate, a foundation trench, pile columns, an anti-seismic layer and a cement gel layer, and is characterized in that the foundation trench is formed inside the ground surface; the connecting steel plate is fixedly arranged inside the foundation trench, the pile columns are fixedly arranged at the bottom of the connecting steel plate, the anti-seismic layer is fixedly arranged on one sides of the pile columns, and the cement gel layer is fixedly arranged on one side of the anti-seismic layer; and bottom grooves are formed in the bottoms of the pile columns, and reset spring layers are fixedly arranged inside the bottom grooves. The anti-seismic foundation structure for the refuges in the soft geological environments such as the sand beaches is simple in structure, convenient touse and practical in function, the fixation and firmness of the pile columns are improved through metal column cores, the pile columns have good supporting performance through a bearing base, and after the metal column cores are poured with reinforcing cement, the weight of the metal column cores is conveniently increased to stabilize the metal column cores.

Description

technical field [0001] The invention discloses an anti-seismic foundation structure that can be used for shelters in soft geological environments such as beaches, and belongs to the technical field of anti-seismic foundation structures. Background technique [0002] For a long time, traditional refuges in soft geological environments such as beaches have mostly used foundations with a large bottom area to increase the load capacity of the foundation. However, the structure has poor seismic resistance. The impact of seismic wave energy caused by crustal fracture or displacement, the larger the bottom area, the greater the force of the impact and the greater the possibility of fracture and displacement, so its anti-seismic effect is poor. In recent years, there have been many earthquakes in my country The disasters caused caused a lot of building damage. Although the current technology has strengthened the building, even if the earthquake did not cause the building to collapse, ...

[0002] For a long time, traditional refuges in soft geological environments such as beaches have mostly used foundations with a large bottom area to increase the load capacity of the foundation. However, the structure has poor seismic resistance. The impact of seismic wave energy caused by crustal fracture or displacement, the larger the bottom area, the greater the force of the impact and the greater the possibility of fracture and displacement, so its anti-seismic effect is poor. In recent years, there have been many earthquakes in my country The disasters caused caused a lot of building damage. Although the current technology has strengthened the building, even if the earthquake did not cause the building to collapse, the building structure was deformed, and the damage to the building was irreversible, making the building unusable. The traditional foundation structure for refuge in geological environment is simple to lay, does not have good protection effect, does not have effective shock absorption, and the integrity of the foundation is poor, and there is no good containment effect when vibration occurs
