Description

Foundation pit supporting device for civil engineering of transformer substation Technical Field The invention relates to the field of foundation pit support, in particular to a foundation pit support device for civil engineering of a transformer substation. Background The foundation pit support refers to temporary support and reinforcement measures adopted in the construction process of building underground engineering, and the temporary support and reinforcement measures are adopted to ensure the stability of soil mass around the foundation pit, control the deformation of surrounding stratum, ensure the construction safety of an underground structure and protect surrounding environment (such as adjacent buildings, roads, pipelines and the like). The method is a core link of deep foundation pit engineering and directly relates to success and failure and safety of the whole project. For example, the patent of publication No. CN119981085A discloses a deep foundation pit supporting structure, which relates to the field of deep foundation pit supporting and comprises that a plurality of groups of deep foundation pit supporting structures can be matched with each other through the matching between a connecting base and supporting bottom plates, when the deep foundation pit supporting structures are needed to support a deep foundation pit, the clamping blocks on one side of a connecting side seat are inserted into fixing slots, so that the plurality of groups of supporting bottom plates can be connected and fixed, a good matching mechanism is arranged between the deep foundation pit supporting structures, the supporting degree between the deep foundation pit supporting structures is further enhanced, the using stability of the deep foundation pit supporting structures is improved, the problem that the common deep foundation pit supporting structures do not have a good matching mechanism when the deep foundation pit supporting structures are matched with each other in multiple groups is solved, the matching fixing degree between the deep foundation pit supporting structures is lower, and the requirements cannot be met. The patent of publication No. CN120006738A discloses a foundation pit supporting device and a foundation pit supporting method, the foundation pit supporting device comprises a foundation pit supporting plate, wherein assembly mechanisms are arranged on two sides of the foundation pit supporting plate, a reinforcing mechanism is arranged on the front surface of the foundation pit supporting plate, each assembly mechanism comprises a limiting strip fixedly connected to the right side of the foundation pit supporting plate, and a plurality of assembly holes are formed in the front surface of each limiting strip. According to the invention, the limit bar on the right side of the foundation pit support plate can be inserted into the limit groove on the left side of the other foundation pit support plate by adopting the cooperation of the limit bar, the assembly hole, the limit groove, the mounting cover, the knob, the screw rod, the push plate, the limit rod and the mounting cover, and then the knob and the screw rod are rotated to drive the push plate and the limit rod to move, so that one end of the limit rod is conveniently inserted into the assembly hole on the front side of the limit bar, and therefore, the two foundation pit support plates are quickly assembled together. The basic principle of foundation pit support is to balance the soil pressure and water pressure outside the foundation pit by utilizing various structural forms, so as to prevent soil from collapsing or excessively settling. The support forms are various according to factors such as foundation pit depth, geological conditions, surrounding environment sensitivity, construction period cost and the like. Common support types include slope excavation, soil nailing walls, composite soil nailing walls, row pile supports (e.g., bored piles, SMW method piles), underground diaphragm walls, internal support systems (concrete supports or steel supports), anchor rod (cable) supports, and the like. In soft soil areas or ultra-deep foundation pits, a combination of 'row piles plus internal supports' or 'underground continuous walls plus multiple supports' is often adopted to provide sufficient rigidity and strength. A complete foundation pit support system is generally composed of an enclosure structure, a support system and a waterproof curtain. The support system (comprising a horizontal support and a vertical upright post) is used for reducing the span of the enclosure structure and controlling the deformation of the enclosure structure, and the waterproof curtain cuts off the groundwater seepage path through the forms of high-pressure jet grouting piles, stirring piles and the like to prevent the ground subsidence caused by water and soil loss outside the pit. In the construction process, foundation pit support emphasizes 'dynamic design
