[0002] In the field of municipal engineering construction, building municipal pipelines is a key link to ensure the normal operation of urban drainage systems. These pipelines bear the task of discharging rainwater and domestic sewage. During pipeline laying, a trench of a certain depth and width needs to be excavated on the ground to accommodate and fix the pipeline. After the trench is excavated, its sidewall is at risk of collapse due to the natural properties of the soil and external factors, which not only endangers the safety of construction personnel but also may affect the quality and progress of pipeline laying.

However, in actual application, the existing pipeline trench support device generally has the following problems: First, the connection between the connecting piece and the guard plate is usually threaded connection or hinged connection. Although these connection methods have a certain flexibility in fixing and adjusting, they are relatively cumbersome and time-consuming when the device needs to be quickly removed or rearranged, affecting the laying efficiency of the device and increasing the construction risk. Second, the length of the connecting piece in the existing support device is usually fixed. Although this design simplifies the production and manufacturing process, it has poor universality when facing trenches of different width sizes. Construction personnel often need to select and replace connecting pieces of different lengths according to the actual width of the trench, which not only increases the construction cost but also may lead to poor support effect or even safety accidents due to mismatched connecting pieces.
