Description

Technical Field

[0001] This utility model relates to the field of support and anchoring technology, specifically a deep foundation pit support and anchoring device. Background Technology

[0002] With social development, the construction of municipal, railway, highway, and building projects involves a large number of deep foundation pit projects. The design scale of deep foundation pits is becoming increasingly larger, with their length and depth constantly increasing. A deep foundation pit refers to an excavation depth exceeding 5 meters, but with particularly complex geological conditions, surrounding environment, and underground pipelines. Deep foundation pit support refers to the measures taken to support, reinforce, and protect the sidewalls and surrounding environment of a deep foundation pit to ensure the safety of underground structure construction and the surrounding environment. It is a component of underground engineering construction, used to stabilize the pit walls for foundation pits with a safe excavation depth greater than 5 meters.

[0003] Currently, support devices are installed inside deep foundation pits to support the inner walls. However, the overall support structure of the anchoring devices used cannot be adjusted in real time after adjustment. Moreover, after installation inside the deep foundation pit, the whole structure is in a fixed state. As the deep foundation pit continues to widen, adjustment is inconvenient, and it needs to be removed before adjustment can be made. This affects the support effect of the deep foundation pit. Utility Model Content

[0004] The purpose of this invention is to provide a deep foundation pit support anchoring device, which has the advantages of real-time adjustment and wide applicability.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a deep foundation pit support and anchoring device, comprising a left reinforcing plate, a positioning frame fixedly installed at the bottom right side of the left reinforcing plate, a right adjusting plate telescopically installed inside the positioning frame, a second support plate fixedly installed at the right end of the right adjusting plate, a first support plate fixedly installed at the left end of the left reinforcing plate, an adjusting knob movably installed on the right side of the top of the positioning frame, a shaft seat fixedly installed at the top right side of the first support plate, an adjustable support rod fixedly installed inside the shaft seat via a bushing, a shaft rod rotatably installed at the right end of the adjustable support rod, and both ends of the shaft rod connected to the top of the positioning frame via connecting plates, a clamping plate fitted against the top left side of the second support plate, and a support rod fixedly installed at the left end of the clamping plate.

[0006] As a preferred embodiment, a telescopic tube is sleeved on the middle surface of the adjustable support rod, and the telescopic end is the left end portion, with a knob installed through the top of the telescopic tube.

[0007] As a preferred embodiment, fixed vertical plates are fixedly installed on both the front and rear sides of the top right end of the positioning frame. The fixed vertical plates have movable grooves inside, and adjustment blocks are slidably installed inside the movable grooves. The right side of the adjustment block is connected to the left end of the support rod, and a threaded rod is rotatably installed inside the adjustment block.

[0008] As a preferred embodiment, the positioning frame has a pull-out groove inside, the left end of the right adjustment plate is located inside the pull-out groove and is slidably connected, and the top of the positioning frame has a threaded groove for the adjustment knob to move.

[0009] As a preferred embodiment, the top of both the first support plate and the second support plate are symmetrically provided with mounting grooves, and the first support plate and the second support plate are symmetrically arranged.

[0010] As a preferred embodiment, a positioning plate is fixedly installed on the top of the fixed vertical plate, and the upper end of the threaded rod passes through the positioning plate and is threadedly connected to the through portion.
