[0001] The invention relates to the technical field of municipal engineering, and in particular to a trenchless pipeline horizontal directional drilling expansion device for municipal engineering. Background Art

[0002] In the laying of municipal engineering pipelines, trenchless horizontal directional drilling technology is an important construction method. Horizontal directional drilling technology uses the drill bit to guide the drilling underground, gradually expand the hole and finally pull the pipeline back into the expanded hole. It can complete the laying of underground pipelines without damaging the surface. It is widely used in areas where it is inconvenient to dig, such as crossing roads and rivers.

[0003] In the prior art, the expansion head usually has the defect of fixed size, and the size of the expanded hole cannot be flexibly adjusted according to construction requirements. Therefore, it is inconvenient to use when encountering pipes of different diameters or complex geological conditions. In addition, since the size of the expansion head is fixed, the equipment needs to frequently replace drill bits of different sizes to adapt to various construction requirements, resulting in reduced construction efficiency and increased equipment cost and maintenance difficulty. To solve the above problems, we propose a trenchless pipeline horizontal directional drilling expansion equipment for municipal engineering. Summary of the invention
