Description

Technical Field

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

[0002] In the field of construction engineering, effective support of the foundation pit slope is essential to ensure the stability of the pit walls and the safety of the surrounding environment during the excavation process. There are many types of existing foundation pit slope support devices, some of which employ adjustable-angle support plate structures to adapt to foundation pit sidewalls with varying slopes.

[0003] For example, existing technologies (such as patent CN115928758B) disclose a foundation pit slope support device, which uses short columns, diaphragms, and rotatable support plates to adjust the angle of the support plates using an adjusting component, thereby conforming to the contours of different slopes for support. However, this device has significant limitations: its support plates are usually of fixed size and cannot be replaced. In actual engineering, the depth, width, and area to be supported of foundation pits vary greatly, and fixed support plate sizes cannot meet diverse construction needs. When encountering small or irregularly shaped foundation pits, excessively large support plates may not be installable or may result in material waste; while when supporting large areas of slopes is required, multiple sets of devices may need to be densely installed due to insufficient area of ​​a single support plate, increasing cost and installation complexity.

[0004] Therefore, there is an urgent need in this field for a foundation pit slope support device that can flexibly adapt to different support area requirements. Utility Model Content

[0005] This utility model addresses the aforementioned shortcomings of existing technologies by providing a foundation pit slope support device that allows for the rapid replacement of baffles of different sizes according to actual site requirements, making it highly versatile. To achieve the above objectives, this utility model provides the following technical solution: A foundation pit slope support device includes a pusher frame and a baffle. The bottom of the pusher frame is connected to a base frame. The pusher frame includes two lower push rods connected to the base frame via a rotating shaft. The lower push rods are arranged in parallel. A slidable upper push rod is inserted into the upper end of each lower push rod. The side wall of the lower push rod is provided with a positioning bolt for fixing the upper push rod. The two upper push rods are connected by an upper connecting rod. The upper connecting rod is connected to the base frame via a positioning mechanism. The baffle is detachably connected to the upper and lower push rods.

[0006] Preferably, the base frame has ear plates on its side wall for fixing, and the upper end of the base frame has a support block connected to the lower push rod.

[0007] Preferably, the side wall of the lower push rod is provided with a relief groove that mates with the end of the upper connecting rod.

[0008] Preferably, adjacent push rods are connected by a lower connecting rod. Preferably, the upper end of the upper push rod and the side wall of the lower push rod are both provided with hooks, and the side wall of the baffle is provided with a hanging sleeve that cooperates with the hooks.

[0009] Preferably, the positioning mechanism includes a support rod connected to the base frame via a pivot and a support sleeve connected to the upper connecting rod via a pivot. The support sleeve and the support rod are inserted into each other, and the side wall of the support sleeve is provided with locking bolts for fixing the support rod.

[0010] Preferably, the support sleeve and the support rod are detachable.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the plug-in structure of the upper and lower push rods, can realize the adjustment of the height of the push frame, thereby adapting to foundation pits of different depths. The detachable connection between the baffle and the push frame allows for quick replacement of baffles of different sizes (such as different heights and widths) according to actual site needs, greatly improving the flexibility of the device. It can be used for local support of small foundation pits, and can also be used to cope with large-area slope support tasks by replacing large-size baffles or installing multiple devices side by side, making it extremely versatile.

[0012] 2. This utility model adopts a stable triangular support structure, which makes the entire support structure stable and able to effectively resist soil pressure. The setting of the lower connecting rod and the upper connecting rod respectively enhances the integrity and rigidity of the bottom push frame and the top structure, ensuring the overall stability of the support device under stress.

[0013] 3. This utility model features a clever folding and storage design. When it needs to be moved or stored, simply loosen the locking bolts to completely pull or separate the support rod from the support sleeve, allowing the support rod to be folded to the side of the base frame, while the support sleeve is close to the push frame, bringing the two together tightly. This significantly reduces the space occupied by the device, greatly facilitating vehicle transportation and warehouse storage, and lowering logistics costs.

[0014] 4. The ear plates and pin holes provided on the base frame of this utility model allow the use of pins (such as steel piles) to quickly anchor the base frame to the ground, making the installation and fixing process simple and quick. The clearance groove on the side wall of the lower push rod ensures that the upper push rod will not interfere with the upper connecting rod during the extension and retraction process, making the height adjustment process smooth and efficient, and improving the efficiency and convenience of on-site construction.
