Description

Technical Field

[0001] The invention relates to the technical field of foundation pit reinforcement, and in particular to a foundation pit reinforcement device used in construction engineering. Background Art

[0002] The foundation pit is an earth pit excavated at the foundation design location according to the base elevation and foundation plane dimensions. Before excavation, the excavation plan should be determined based on geological and hydrological data and the situation of nearby buildings on site, and waterproofing and drainage work should be done. If the excavation is not deep, the side slope can be used to stabilize the soil slope, and the slope size is determined according to relevant construction regulations. If the excavation is deep and there are buildings nearby, the foundation pit wall support method and shotcrete wall protection method can be used. Large foundation pits can even use underground continuous walls and column-type bored pile interlocking methods to prevent the outer soil layer from collapsing. If there is no impact on nearby buildings, the well point method can be used to lower the groundwater level and use slope open excavation. In cold areas, natural cold air freezing method can be used for excavation, etc. The bottom of the current foundation pit reinforcement device is fixed with bolts. Since the fixing method is relatively simple and the pressure easily causes the reinforcement device to tilt, this will affect the effect of subsequent foundation pit reinforcement. In addition, when encountering a deeper foundation pit, it is inconvenient to install and connect multiple reinforcement plates, which affects the practicality of the device. For this reason, we propose a foundation pit reinforcement device for construction projects. Summary of the invention
