[0002] In recent years, urban renewal and renovation has become an important part and a hot topic for relieving people's difficulties, improving the living environment, and enhancing the quality of the city. Among them, the renovation of urban municipal roads is an important part of urban renewal and renovation projects. During the excavation of trenches, the loose soil often leads to the collapse of trench slopes, which can cause casualties in severe cases. Therefore, corresponding protective measures should be taken during the trench excavation process to ensure the stability of the trench slopes.

[0003] In the process of realizing this invention, the inventors discovered at least the following problems in the prior art:

[0004] Although municipal pipeline support devices can support the slopes on both sides of the trench, most of the current support devices are straight supports. Some municipal pipeline trenches have corners during excavation, and the existing support devices can only provide straight supports. There will be gaps in the support at the corners, which can easily lead to collapse.

[0005] Therefore, the aforementioned technical problems need to be solved. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a municipal pipeline trench excavation support device, which solves the problem that straight support plates are not convenient for supporting the soil slope at the corner when trench excavation turns, resulting in gaps and thus causing the trench to collapse at the turning point.

[0023] Please see Figures 1-5 A municipal pipeline trench excavation support device includes a front support plate 1 and a rear support plate 101 located at the rear end of the front support plate 1. The front end of the rear support plate 101 is provided with a receiving groove 102. A seamless folding plate 103 is movably installed inside the receiving groove 102. The front end of the seamless folding plate 103 is fixedly connected to the rear end of the front support plate 1. A sliding groove 104 is provided at the top and bottom of the receiving groove 102. A first slider 105 is fixedly installed at the bottom and top of the rear end of the seamless folding plate 103, and the first slider 105 is slidably installed inside the sliding groove 104.

[0024] With the above-described structural design, when the municipal pipeline trench excavation support device needs to support the corner of the trench, firstly, by pulling the front support plate 1 and the rear support plate 101, the first slider 105 slides inside the slide groove 104, causing the seamless folded plate 103 to be pulled out from inside the receiving groove 102. Then, the seamless folded plate 103 is rotated to a suitable angle according to the angle of the trench turn, making it convenient for workers to use the front support plate 1, the rear support plate 101, and the receiving groove 102 to provide anti-collapse support for the corner of the trench. This avoids the problem that the straight support plate is not convenient for supporting the slope at the corner when the trench is excavated and turns, resulting in gaps and thus causing the trench to collapse.

[0025] Furthermore, a limiting groove 106 is provided at the rear end of the front support plate 1, and a groove 107 is provided at the bottom of the limiting groove 106. A rotating rod 108 is rotatably installed through the limiting groove 106. A limiting block 109 is fixedly installed at the front end and rear end of the bottom of the rotating rod 108. An insert 110 extending into the limiting groove 106 is fixedly installed at the front end of the rear support plate 101. A limiting hole 111 is provided horizontally inside the insert 110. When the front support plate 1 and the rear support plate 101 are closed, the insert 110 extends into the interior of the limiting groove 106. Then, the rotating rod 108 is rotated to make the limiting block 109 horizontal. Then, the rotating rod 108 is moved downward to make the limiting block 109 extend through the limiting hole 111 into the interior of the groove 107. Then, the rotating rod 108 is rotated to make the limiting block 109 vertical to limit and fix the insert 110, so that the seamless folding plate 103 is stored in the interior of the storage groove 102. At this time, the front support plate 1 and the rear support plate 101 are fixed in a straight plate state, which facilitates the straight support.

[0026] Furthermore, a slide rail 2 is fixedly installed on the inner side of the front support plate 1 and the rear support plate 101. A second slider 201 is slidably installed inside the slide rail 2. A circular hole 202 is evenly opened through the inside of the slide rail 2.
