Description

Technical Field

[0001] The utility model relates to a prefabricated pipe trench, in particular to a small prefabricated pipe trench connection structure. Background Art

[0002] The prefabricated trench is composed of U-shaped prefabricated trench segments and prefabricated trench covers. The prefabricated trench segments are connected to form a trench as a whole. Water, electricity, heating and other pipelines are laid in the prefabricated trench. The prefabricated trench is processed by fixed length, which can be factory-produced in batches. The molding quality is good, and it can achieve the effect of plain concrete, which fully meets the functional requirements.

[0003] At present, when connecting the prefabricated pipe trenches hoisted into the trench, in order to ensure the waterproof effect, cement is usually applied to the segments of each prefabricated pipe trench to perform sealing and waterproofing treatments. However, there is no connection support between the prefabricated pipe trenches before the treatment, which easily causes the prefabricated pipe trenches to be skewed and offset during the subsequent connection and waterproofing treatment. It is inconvenient to perform waterproofing treatment on each prefabricated pipe trench when connecting the prefabricated pipe trenches, resulting in low efficiency in connecting the prefabricated pipe trenches.
