Description

Technical Field

[0001] This utility model relates to the field of foundation pit support technology, specifically a hydraulic support structure for foundation pit support. Background Technology

[0002] Foundation pit support is a temporary support, reinforcement, and protection measure taken for the sidewalls and surrounding environment of a foundation pit to ensure the safety of foundation pit excavation and underground structure construction. Its core is to stabilize the soil, control deformation, and protect surrounding facilities. Among them, hydraulic support structure for foundation pit support is a temporary support system set up during foundation pit excavation to ensure construction safety. Hydraulic support structure is usually composed of hydraulic cylinders and support rods, support plates and connectors, hydraulic control system, auxiliary components, etc. Hydraulic support structure is suitable for deep foundation pits with high safety levels and narrow construction spaces.

[0003] For example, Chinese patent CN219547822U, entitled "A Support Structure for Foundation Pit Protection," includes a base plate, columns, and connecting columns. A rod is installed through the inner bottom wall of the base plate, and a first spring is installed around the outer wall of the rod. A compression plate is installed on the top of the rod. A column is installed on the top of the base plate, and two sets of connecting columns are installed through the outer wall of the column. Two sets of stabilizing rods are installed on the outer wall of the column. A rotating rod is installed through the outer wall of the base plate, with a handle at one end. A limit rod is installed through the outer wall of the handle, and multiple cams are installed on the outer wall of the rotating rod. A storage cavity is installed on the inner wall of the column, and a limit ring is installed on the inner wall of the column. One end of the connecting column is located inside the limit ring. A support plate is installed at one end of the connecting column, and an anti-slip block is installed on the outer wall of the support plate. Multiple anti-slip protrusions are installed on the outer wall of the anti-slip block. A connecting block is installed at one end of the stabilizing rod, and an anti-slip plate is installed at the bottom of the connecting block. Multiple diagonal rods are installed at the bottom of the anti-slip plate.

[0004] While the existing technologies mentioned above can enable the use of support structures, in practical applications, it is difficult to add support components to the support structure. Usually, the support components are welded to the support structure, which means that in special scenarios where support components need to be added, the support structure must be replaced, thus reducing the construction efficiency of the project. On the other hand, the position and state adjustment of the support components are not convenient enough. Usually, when the support structure needs to be adjusted to a vertical state, additional hoisting tools are required, which increases the complexity of the support structure adjustment. Therefore, they do not meet the current needs. In response, we propose a hydraulic support structure for foundation pit retaining. Utility Model Content

[0005] The purpose of this utility model is to provide a hydraulic support structure for foundation pit protection, so as to solve the problems mentioned in the background art, such as the difficulty in adding support components to the support structure and the inconvenience of adjusting the position and state of the support components.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic support structure for foundation pit protection, comprising a support plate, two support plates symmetrically distributed, a fixing frame fixedly disposed at the center of the inner side of the support plate, a sliding groove disposed at the center of the fixing frame, the sliding groove having a through structure, a plurality of first through holes disposed inside the upper and lower ends of the fixing frame, the first through holes being equidistantly distributed, three fixing seats disposed inside the sliding groove, the fixing seats sliding and limiting the sliding groove, the fixing seats being equidistantly distributed, and a fourth through hole disposed inside the fixing seat, the fourth through hole corresponding to the position of the first through hole.

[0007] Preferably, a first bolt is provided inside the first through hole, the lower end of the first bolt extends through the fourth through hole to the bottom of the fixing frame, and a second nut is sleeved on the outside of the lower end of the first bolt.

[0008] Preferably, a mounting base is fixedly provided on one side of the fixed base, and a rotating cavity is provided at the center of the mounting base. One side of the rotating cavity is an open structure. A connecting plate is provided inside the rotating cavity. The connecting plate rotates and engages with the rotating cavity, and one side of the connecting plate extends to the outside of the rotating cavity. A rotating seat is fixedly provided on the outside side of the connecting plate.

[0009] Preferably, the mounting base has a second through hole at the top, bottom, front and rear ends. The second through hole has a through structure. The connecting plate has a third through hole, which corresponds to the position of the second through hole. A second bolt is installed inside the second through hole. The second bolt extends through the third through hole to the outside of the mounting base. A first nut is sleeved on the outside of the second bolt.

[0010] Preferably, the support plate is fixedly provided with a number of scale lines on the inner side above the fixed frame. The scale lines are evenly distributed and correspond to the position of the fixed seat.

[0011] Preferably, a hydraulic telescopic device is fixedly installed between the rotating seats.

[0012] Preferably, a plurality of rubber strips are fixedly provided on the outer side of the support plate, and the rubber strips are distributed at equal intervals.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model can adjust the installation gap of the hydraulic telescopic device through the first through hole and the first bolt. When a new hydraulic telescopic device needs to be added, the position adjustment of the support plate has been completed. Then, the fixed seats on both sides of the new hydraulic telescopic device are placed into the slide groove until the new hydraulic telescopic device is placed in a suitable position. At this time, the operator aligns the first bolt with the opening of the first through hole and inserts it into the first through hole until the lower end of the first bolt extends to the bottom of the fixed frame through the fourth through hole. At this time, the second nut is sleeved on the outside of the first bolt and rotated until the second nut is adjusted to a suitable position to complete the fixing of the fixed seat, thereby improving the flexibility of the installation of the hydraulic telescopic device.

[0015] (2) This utility model can adjust the placement of the support plate through the connecting plate and the rotating cavity. When it is necessary to adjust the placement of the support plate, only the hydraulic telescopic device in the middle position is placed between the support plates. Then the operator rotates the support plate so that the support plate rotates on both sides of the hydraulic telescopic device until the support plate is rotated to a vertical position. At this time, the operator aligns the second bolt with the opening of the second through hole and the third through hole and inserts it into the second through hole so that the other end of the second bolt extends to the outside of the mounting base. Then the second bolt is fixed by the first nut to complete the placement adjustment of the support plate, thereby improving the convenience of the support plate adjustment.

[0016] (3) The position of the fixed seat can be confirmed by the scale line. When installing a new hydraulic telescopic device, the hydraulic telescopic device is placed between the fixed frames. At this time, the operator pushes the hydraulic telescopic device so that the fixed seats on both sides of the hydraulic telescopic device move inside the slide groove until the fixed seat is moved to the appropriate position. At this time, the operator observes the scale line so that the new hydraulic telescopic device and the old hydraulic telescopic device are equidistantly distributed, so that the supporting force is evenly distributed, thereby improving the accuracy of the installation of the hydraulic telescopic device.
