Description

Technical Field

[0001] The utility model relates to a supporting structure, in particular to an underground continuous wall supporting structure, belonging to the technical field of construction engineering. Background Art

[0002] Underground continuous wall is a foundation project that uses a trenching machine on the ground. Along the peripheral axis of the deep excavation project, under the condition of mud wall protection, a long and narrow deep trench is excavated. After the trench is cleared, a steel cage is hung in the trench, and then underwater concrete is poured using the conduit method to form a unit trench section. This is carried out section by section to build a continuous reinforced concrete wall underground. It serves as a water-cutting, anti-seepage, load-bearing and water-retaining structure. When excavating the underground continuous wall trench, the soil close to the surface is extremely unstable and prone to collapse, so support is required.

[0003] In the application number "201920284175.8" and the name "A kind of underground continuous wall support structure", a solid support body is formed inside the continuous wall through the support structure to prevent collapse. It is suitable for the production and use of underground continuous wall support structures. However, during use, it is necessary to swing the two pressing handles in turn to adjust the position of the top of the hydraulic jack, which is relatively laborious to adjust. In particular, when the distance between the inner wall of the continuous wall changes greatly, it takes a lot of time to swing the hydraulic jack to adjust the distance, which is not convenient for quick adjustment, resulting in poor convenience of use. Moreover, it only supports the top of the support steel plate, but not the bottom of the support steel plate, which can easily cause uneven support force, thereby reducing the support effect. Utility Model Content

[0004] The purpose of the present utility model is to provide an underground continuous wall support structure in order to solve the above problems. When the distance between the inner walls of the continuous wall changes, the support plate can be quickly supported, thereby improving the convenience of operation and being able to support the support plate more comprehensively, effectively improving the support effect.

[0005] The utility model achieves the above-mentioned purpose through the following technical solutions: an underground continuous wall support structure, including a support plate, a fixed structure is provided on the support plate, one of the support plates is fixedly connected to two connecting sleeves, a first support rod is clamped on the connecting sleeve, the first support rod is slidably connected to the second support rod, the second support rod is threadedly connected to a first screw rod, one end of the first screw rod is rotatably connected to a stop block, the stop block is in contact with the other support plate, two connecting seats are fixedly connected to the first support rod, a blocking block is rotatably connected to the connecting seat, a plurality of slots are provided on the second support rod, two of the blocking blocks are clamped with two of the slots, and a spring is in contact between the blocking block and the second support rod.

[0006] Preferably, a handle is fixedly connected to the first screw rod, and the entire cross-section of the handle is a "cross" structure.

[0007] Preferably, the transverse cross-section of the first support rod is a rectangular structure, and one end of the longitudinal cross-section of the first support rod is a trapezoidal structure.

[0009] Preferably, a plurality of ribs are fixedly connected to the bottom end of one side of the support plate, and the plurality of ribs are linearly and equidistantly distributed.

[0010] Preferably, the support plate is provided with a reinforcement structure, and the reinforcement structure includes a guide column and a connecting plate. Two guide columns are fixedly connected to the support plate, one end of the two guide columns is fixedly connected to the same connecting plate, and the two guide columns are slidably connected to the same connecting plate, and a plurality of steel nails are fixedly connected to the connecting plate. A second screw rod is rotatably connected to the connecting plate, and the second screw rod is rotatably connected to the support plate, and the second screw rod and the connecting plate are threadedly connected.

During the movement, the second support rod will contact the clamping block and rotate on the connecting seat. At this time, the clamping block will not limit the movement of the second support rod, and the movement of the second support rod will drive the first screw rod and the blocking block to move synchronously. Therefore, by pulling the second support rod, the blocking block can be quickly approached to the supporting plate. When the blocking block is close to the supporting plate, the second support rod is stopped. At this time, the spring Under the action of the spring, the two blocking blocks will be engaged with the two blocking slots, so that the second support rod cannot move in the opposite direction, and then the first screw rod can be rotated, and the first screw rod will drive the blocking block to move toward the support plate.
