Description

Technical Field

[0001] The utility model relates to the technical field of drainage devices, in particular to a foundation pit drainage device. Background Art

[0002] With the rapid development of urban construction, underground spaces for various purposes have been developed and utilized in major and medium-sized cities, such as multi-story basements of high-rise buildings, underground stations, underground parking garages, underground shopping malls, underground warehouses, underground air defense works, and various underground civil and industrial facilities. Deep foundation pit engineering has become increasingly well-known, and deep foundation pit dewatering is one of the most commonly used methods in the excavation process. In actual projects, it is not uncommon to see cases where support engineering fails or causes serious environmental problems in the surrounding area due to careless dewatering. At present, the main solutions are "blocking", that is, setting up an anti-seepage wall outside the support structure; the second is "diversion", that is, extracting groundwater to reduce the groundwater head. The "blocking" method is expensive and once the anti-seepage wall fails or pipe bursts occur, the remedial work is very difficult, while the "diversion" method may have adverse effects on the surrounding environment, causing cracks in adjacent buildings and ground subsidence. Therefore, the environmental problems caused by dewatering are particularly important for deep foundation pit engineering, and they must be analyzed and studied in depth.

[0003] On-site investigations have revealed that traditional foundation pit dewatering and building inspections result in significant waste, with a high proportion of labour costs, and are not capable of real-time inspections. They are relatively simple and, especially at night, it is impossible to obtain accurate data.

[0004] In addition, during the construction process, it is often impossible to effectively utilize the precipitation and rainwater in the foundation pit. This project plans to conduct innovative research in three aspects: research on intelligent technology for recycling foundation pit water, research on settlement detection technology for surrounding buildings and municipal roads, and research on rainwater recycling technology for construction sites, aiming to maximize the utilization of water resources without affecting the surrounding environment.

[0005] In view of this, the utility model proposes a foundation pit drainage device. Utility Model Content
