Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] This utility model embodiment provides a municipal pipeline foundation pit excavation support device, such as... Figure 1-4 As shown, the support device includes two sets of support plates 1 arranged opposite each other. Each set of support plates 1 is composed of multiple support plates 1 spliced ​​from top to bottom. The support device also includes a support assembly 2 for connecting the two sets of support plates 1. The support assembly 2 includes a support rod 21. Both ends of the support rod 21 are provided with vertical insertion rods 22. Each support plate 1 has a connecting sleeve 11 on its upper and lower sides. The insertion rod 22 at one end of the support rod 21 is inserted into the connecting sleeve 11 of two adjacent support plates 1 on one set of support plates 1. The insertion rod 22 at the other end of the support rod 21 is inserted into the connecting sleeve 11 of two adjacent support plates 1 on the other set of support plates 1. By providing connecting sleeves 11 on the upper and lower sides of the support plate 1 and inserting rods 22 at both ends of the support rod 21, the two adjacent support plates 1 on the same set of support plates 1 can be connected and disconnected. Therefore, the height of the support device can be adjusted according to the depth of the pipeline pit, thus having a wide range of applications.

[0020] In this embodiment, the insertion rod 22 is fixed inside the connecting sleeve 11 by the first fixing member 3, so that the connection between two adjacent support plates 1 is more secure, thereby improving the overall structural stability of the support device. In this embodiment, the first fixing member 3 adopts a first pin, and both ends of the insertion rod 22 are provided with first pin holes 221. The connecting sleeve 11 is provided with a second pin hole 111. The first pin is fixed inside the first pin hole 221 and the second pin hole 111, which can facilitate the disassembly and reassembly between two adjacent support plates 1 of the same group of support plates 1. The first fixing member 3 of this utility model is not limited to the form of a first pin. For example, in some other embodiments, the first fixing member 3 adopts a bolt threaded to the connecting sleeve 11, which can also facilitate the disassembly and reassembly between two adjacent support plates 1 of the same group of support plates 1.

[0021] In this embodiment, the support rod 21 includes a sleeve 211. Telescopic rods 212 are movably installed inside both ends of the sleeve 211. Insert rods 212 are vertically installed at opposite ends of the two telescopic rods 212. The telescopic rods 212 and the sleeve 211 are connected by a second fixing member 4 for fixing the relative position of the telescopic rods 212 and the sleeve 211. By adjusting the relative position of the telescopic rods 212 and the sleeve 211, the length of the support rod 21 can be adjusted, thereby adjusting the spacing between the two sets of support plates 1 to accommodate pipe pits of different widths. In this embodiment, the second fixing member 4 is a second pin. Insert rods 22 are installed at opposite ends of the two telescopic rods 212. The sleeve 211 has a third pin hole 2121 and a plurality of fourth pin holes 2111 are provided at equal intervals on the sleeve 211.

The lifting member 5 designed as described above can easily lift the entire support device, thereby making it easy to move the entire support device.

[0023] Specific principle: When installing the support device, the length of the support rod 21 is adjusted according to the width of the pipeline pit. After adjustment, an appropriate number of support plates 1 are selected according to the depth of the pipeline pit and spliced ​​into two sets of support plates 1. The insertion rod 22 at one end of the support rod 21 is inserted into the connecting sleeve 11 on the adjacent two support plates 1 of one set of support plates 1. The insertion rod 22 at the other end of the support rod 21 is inserted into the connecting sleeve 11 on the adjacent two support plates 1 of the other set of support plates 1. This connects the two sets of support plates 1 and the adjacent two support plates 1 of the same set of support plates 1, thus completing the installation of the entire support device. Therefore, the height of the support device can be adjusted according to the depth of the pipeline pit, making it widely applicable.
