[0002] Foundation pit support is a measure of support, reinforcement and protection of the foundation pit side walls and surrounding environment to ensure the safety of underground structure construction and the surrounding environment of the foundation pit.

[0003] For example, the authorization announcement number is "CN213390162U", which is an easy-to-install foundation pit support device. Although it solves the problem of the existing easy-to-install foundation pit support device, it takes a certain amount of time for the reinforced concrete body to be poured and solidified, and the construction is relatively cumbersome, which causes inconvenience to the staff. The above-mentioned support plate and the support plate are mortised, and the stabilizing plate and the support plate are mortised, which facilitates the staff to install the foundation pit support device and improves the installation efficiency. Taking into account the unevenness of the foundation pit, it is necessary to fix the plug plate to the foundation pit in advance, and then slide the support plate into the inside of the plug plate for fixing. The support plate and the plug plate are in a vertical state, and the support distance between the support plate and the foundation pit cannot be adjusted. During installation, it is necessary to ensure that the installation distance of the plug plate is accurate, otherwise the support effect cannot be guaranteed, resulting in the need for precise installation during the work process, which increases the difficulty of installation. Utility Model Content

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] Example 1:

[0021] See also Figure 1-6 : In this embodiment, a support device for installing a foundation pit includes a support plate 1 and an insert plate 2. The outer wall of the support plate 1 is fixedly connected to the insert plate 2, the outer wall of the insert plate 2 is fixedly connected to the first fixed block 3, the inner wall of the first fixed block 3 is movably connected to the fixing screw 4, the outer wall of the fixing screw 4 is threadedly connected to the nut 5, the outer wall of the nut 5 is tightly pressed against the first fixed block 3, and the outer wall of the support plate 1 is connected to a reinforcing mechanism 6.

[0022] The reinforcing mechanism 6 includes a first fixed seat 601, and a triangular supporting force is formed between the first fixed seat 601 and the second fixed seat 603 at both ends through the reinforcing rod 602, so as to strengthen the supporting force between the support plate 1 on the first fixed seat 601 and the plug plate 2 on the second fixed seat 603. The outer wall of the first fixed seat 601 is fixedly connected to the support plate 1, the inner wall of the first fixed seat 601 is tightly pressed against the reinforcing rod 602, the end of the reinforcing rod 602 is tightly pressed against the second fixed seat 603, the inner wall of the second fixed seat 603 is threadedly connected to the fixing screw 604, and the outer wall of the fixing screw 604 is tightly pressed against the fixing plate 605.

[0023] The outer wall of the support plate 1 is fixedly connected to the gasket 8. The surface of the gasket 8 is made of stainless steel with a concave and convex surface, which can improve the strength of the deformation of the support plate 1 under the downward pressure, and can also play a role in the firm contact between the gasket 8 and the foundation pit. The outer wall of the plug-in plate 2 is connected with the mounting mechanism 7, which slides into the interior of the mounting plate 702 through the trapezoidal bar 701 to achieve the fixation between the mounting plate 702 and the plug-in plate 2. The mounting mechanism 7 includes a trapezoidal bar 701, the outer wall of the trapezoidal bar 701 is fixedly connected to the plug-in plate 2, the outer wall of the trapezoidal bar 701 is slidably connected to the mounting plate 702, and the inner wall of the mounting plate 702 is processed with a mounting hole 703;

[0024] The reinforcing screws 9 on the mounting plate 702 are inserted into the side wall of the foundation pit. After the mounting plate 702 is completely fixed to the cement of the side wall of the foundation pit, the trapezoidal bars 701 with the same distance from the inserting plate 2 can be slid into the mounting plate 702 in a staggered manner, so that the distance between the supporting plate 1 on the inserting plate 2 and the upper end of the foundation pit can be changed, thereby achieving the effect of supporting the foundation pit by the supporting plate 1, which will make installation more convenient.

[0025] Working principle:

[0026] Installation phase

[0027] First, insert the reinforcing screws 9 on the mounting plate 702 into the side wall of the foundation pit. After the mounting plate 702 is completely fixed to the cement of the side wall of the foundation pit, slide the trapezoidal bar 701 on the plug plate 2 into the mounting plate 702, so that the support plate 1 on the plug plate 2 can directly support the upper end of the foundation pit 11. At the same time, in order to strengthen the bearing capacity of the support plate 1, after the upper end of the reinforcing rod 602 is inserted into the interior of the first fixing seat 601, the lower end is inserted into the interior of the second fixing seat 603 again, and fixed to the second fixing seat 603 by the fixing screws 604 on the fixing plate 605. The reinforcing rod 602 inside the second fixing seat 603 is limited and fixed, which can achieve the effect of improving the bearing capacity of the support plate 1 in supporting the foundation pit.

[0030] Working principle:

[0031] In order to ensure the stability between the support plate 1 and the mounting plate 702, it is necessary to pass the fixing screw 4 through the first fixing block 3 and the second fixing block 10, and screw the fixing screw 4 into the nut 5 for limiting and fixing, so that the plug-in plate 2 on the first fixing block 3 and the second fixing block 10 and the mounting plate 702 can be fixed.
