[0030] Example 2

[0031] See also Figure 3-5 , the utility model provides the following technical solutions:

[0032] The support mechanism 4 includes a support rod 401, an arc block 402, a slider 403, a positioning groove 404 and a slot 405. The support rod 401 is arranged on the top of the positioning plate 1, one side of the support rod 401 is rotatably connected to the arc block 402, one side of the arc block 402 is fixedly connected to the slider 403, one side of the slider 403 is provided with a positioning groove 404, and one side of the arc block 402 is provided with a slot 405.

[0033] The pushing mechanism 3 includes a fixed block 301, a slide groove 302, a limiting groove 303, a positioning hole 304, a pedal 305 and a mounting plate 306. The fixed block 301 is fixedly installed on the top of the positioning plate 1. The top of the fixed block 301 is provided with a slide groove 302, one side of the slide groove 302 is provided with a limiting groove 303, one side of the limiting groove 303 is provided with a positioning hole 304, and the pedal 305 is arranged on the top of the fixed block 301, and one side of the pedal 305 is fixedly connected with a mounting plate 306.

[0034] The support rod 401 is rotatably connected to the inside of the arc block 1 2 , and the support rod 401 is rotatably connected to the inside of the arc block 2 402 .

[0035] The arc block 2 402 is slidably connected inside the slide groove 302 , and the slider 403 is slidably connected inside the limit groove 303 .

[0036] The mounting piece 306 is slidably inserted into the slot 405 , and the pedal 305 is fixedly mounted on one side of the arc block 2 402 .

[0037] The following further explanation is required: the positioning plate 1 and the positioning plate 2 101 are inserted into the soil of the deep foundation pit through the positioning spikes 102 and the positioning spikes 2 103, and then the pedal 305 is pressed so that the pedal 305 drives the arc block 2 402 to slide inside the slide groove 302, and at the same time drives the support rod 401 to move from one side of the positioning plate 1 to the side close to the positioning plate 2 101. The force of pushing the support rod 401 causes the positioning plate 1 to move to the side away from the positioning plate 2 101. At the same time, due to the positioning spikes 102 set at the bottom, the positioning plate 1 is deeply embedded in the soil at the bottom of the deep foundation pit, and due to the force of pushing the support rod 401, the positioning plate 2 101 is also moved upward. At the same time, due to the positioning spikes 2 103 set at the bottom, the positioning plate 1 is deeply embedded in the soil on the side of the deep foundation pit, and then the arc block 2 402 is fixed to the inside of the fixed block 301 by the positioning rod 203, which is convenient for positioning the positioning plate 1 and the positioning plate 2 101.

[0038] Working principle: When a deep foundation pit support structure is used, first, a positioning spike 102 is arranged at the bottom of the positioning plate 1, and the positioning spike 102 facilitates the positioning plate 1 to be inserted into the soil at the bottom of the deep foundation pit. A positioning spike 103 is arranged on one side of the positioning plate 101, and the positioning spike 103 facilitates the positioning plate 101 to be inserted into the soil on the side of the deep foundation pit. The positioning plate 1 and the positioning plate 101 are connected to the support mechanism 4 through the arc block 2. A pushing mechanism 3 is arranged on the top of the positioning plate 1, and the pushing mechanism 3 facilitates the adjustment of the position of the support mechanism 4, so that the positioning plate 1 and the positioning plate 101 are deeply inserted into the soil of the deep foundation pit, which is convenient for supporting the deep foundation pit.

[0039] When it is necessary to support the deep foundation pit, firstly, the positioning plate 1 and the positioning plate 2 101 are inserted into the soil of the deep foundation pit through the positioning spikes 102 and the positioning spikes 103, and then the pedal 305 is pressed to make the pedal 305 drive the arc block 2 402 to slide inside the slide groove 302, and at the same time drive the support rod 401 to move from one side of the positioning plate 1 to the side close to the positioning plate 2 101. Due to the force of pushing the support rod 401, the positioning plate 1 moves to the side away from the positioning plate 2 101. At the same time, the positioning spike 102 arranged at the bottom makes the positioning plate 1 penetrate into the soil at the bottom of the deep foundation pit, and the force of pushing the support rod 401 also makes the positioning plate 101 move upward, and at the same time, the positioning spike 103 arranged at the bottom makes the positioning plate 1 penetrate into the soil on the side of the deep foundation pit, and then the arc block 2 402 is fixed inside the fixed block 301 by the positioning plug rod 203, so as to facilitate the positioning of the positioning plate 1 and the positioning plate 2 101, and the device is convenient for supporting the deep foundation pit.
