Description

Technical Field

[0001] The invention belongs to the technical field of excavation equipment, and in particular relates to an integrated chain tooth type trench excavation equipment and application thereof. Background Art

[0002] In water network and swamp areas, oil and gas pipelines, water pipelines and other projects that require trenching often use excavators. However, due to the low bearing capacity of the foundation in the water network area, it is difficult to form the trench and large equipment is difficult to enter. Conventional equipment often sinks into the stratum, making it difficult to construct. Currently, the existing construction mainly adopts the following two methods: one is to use a specially made amphibious excavator with widened tracks to appropriately reduce the ground deviation and adapt to a certain degree of soft strata, but in areas with low bearing capacity of the foundation, there is still a risk of equipment sinking, and large pipelines are difficult to transport and difficult to implement; the second is to adopt auxiliary measures such as foundation replacement, precipitation, diversion, drying, laying steel plates, etc., but this method is greatly affected by weather factors, and the project volume is large, the cost is high, and the construction period is long. Summary of the invention

[0003] In order to solve the deficiencies of the prior art, the present invention provides an integrated chain tooth type trench excavation equipment and its application. In the present invention, the spiral propulsion vehicle realizes the driving and material transportation functions of heavy equipment in soft strata, and provides power for the trench excavation device.
