In the process of developing the urban underground space, construction operations such as excavation of a foundation pit and the like are generally required. The open cut method is gradually one of the most commonly used methods in excavation of foundation pits due to the advantages of low construction cost, mature technology and the like. Since the excavation of the foundation pit by the open cut method is usually carried out outdoors, the influence of factors such as weather is obvious. In areas with abundant rainfall, such as the east south coast, the annual rainfall is usually over 1000mm, the duration of a rainy season is long, and water accumulation in the pit is easy to cause, so that the safety of the foundation pit is influenced. In addition, the open cut foundation pit is exposed to burning sun in summer due to high temperature weather, so that the operation time is obviously influenced, and the construction efficiency is reduced. Therefore, a canopy is erected above the open cut foundation pit for preventing rain and shading sun, and the construction environment can be effectively improved. However, the erection of the canopy affects the operation of the gantry crane, so that in order to ensure safe and efficient implementation of foundation pit excavation, equipment which is suitable for specific difficulties in the excavation process needs to be developed.
