Description

Technical Field

[0001] The utility model relates to the technical field of support devices, in particular to a foundation pit anti-collapse support device. Background Art

[0002] During construction, the foundation pit is affected by factors such as rainy weather and ground overload, resulting in major safety hazards. Therefore, when excavating the foundation pit, support devices are needed to prevent the side wall soil from collapsing.

[0003] For example, the Chinese patent application number is CN219886853U, which is a collaborative support device for preventing foundation pit collapse, comprising two groups of panel walls; the two groups of panel walls are vertically arranged at opposite sides of the foundation pit in parallel and at intervals, and a positioning structure is installed on the inner side of each group of panel walls; a connecting structure is hinged between the two groups of positioning structures. Although the above structure can effectively prevent foundation pit collapse, the force-bearing device of the existing support device is located at the center of the wall panel, resulting in the bottom and top ends of the wall panel being bent inward when squeezed by soil and rocks, thereby causing damage to the wall panel. Therefore, the inventor proposes a foundation pit anti-collapse support device to solve the problem. Utility Model Content

[0004] The purpose of the utility model is to provide a foundation pit anti-collapse support device to solve the problem that the force-bearing device of the existing support device is located at the center of the wall panel, which causes the bottom and top ends of the wall panel to bend inward when the wall panel is squeezed by soil and rocks, thereby causing damage to the wall panel.

[0006] As a technical solution of the present invention, a first wall panel is provided on one side of the first mounting plate, and a plurality of first positioning rods are provided on one side of the first wall panel so that the first positioning rods can position the first wall panel.

[0007] As a technical solution of the present invention, a first bottom plate is provided at the bottom end of the first wall panel, and a first reinforcing rib is provided at the center of the upper end surface of the first bottom plate so that the first reinforcing rib increases the connection strength between the first wall panel and the first bottom plate.

[0008] As a technical solution of the present invention, a second adjusting rod is installed inside the other end of the mounting tube through a second external thread, and a second fixing sleeve is provided outside one end of the second adjusting rod to facilitate the second external thread to install the second adjusting rod inside the mounting tube.

[0009] As a technical solution of the present invention, a second fixed base is provided at one end of the second fixed sleeve, and four groups of second support rods are obliquely provided on the outside of the second fixed base so that the second fixed sleeve can fix the second fixed base at one end of the second adjusting rod.

[0010] As a technical solution of the present invention, a second mounting plate is provided at one end of the second support rod, and a second wall panel is provided on one side of the second mounting plate to facilitate fixing the second wall panel on one side of the second mounting plate.

[0011] As a technical solution of the present invention, a plurality of second positioning rods are provided on one side of the second wall panel. The second positioning rods adopt a conical structure so that the second wall panel can be positioned by the second positioning rods.

[0012] As a technical solution of the present invention, a second bottom plate is provided at the bottom end of the second wall panel, and a second reinforcing rib is provided at the center of the upper end surface of the second bottom plate so that the second reinforcing rib increases the connection strength between the second bottom plate and the second wall panel.

[0013] Compared with the prior art, the beneficial effects of the present invention are: the foundation pit anti-collapse support device is not only reasonable in structure, easy to use and simple to maintain in the later stage, but also has the following advantages:

[0014] (1) The utility model installs the first adjusting rod inside one end of the mounting tube through the first external thread, and then fixes the first fixed base to one end of the first adjusting rod through the first fixing sleeve, and then obliquely arranges four groups of first supporting rods on the outside of the first fixing base, arranges a first mounting plate at one end of the first supporting rod, and fixes the first mounting plate to one side of the first wall panel, so that the second supporting rod fixes the first wall panel through the second mounting plate, which solves the problem that the supporting force is concentrated at the center of the board wall when the support device reinforces the board wall, thereby enhancing the strength of the board wall.

[0015] (2) The utility model provides a hexagonal boss on the outside of the mounting tube and an internal thread on the inside of the mounting tube, so that the first adjusting rod and the second adjusting rod are respectively installed inside the two ends of the mounting tube through the first external thread and the second external thread. When the mounting tube is controlled to rotate by the hexagonal boss, the first adjusting rod and the second adjusting rod move laterally along the inside of the internal thread through the first external thread and the second external thread, so that the width of the support device can be quickly adjusted. In addition, the support device has a simple structure and can be installed quickly, thereby improving assembly efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
