Technical Field

[0001] The utility model relates to the technical field of civil engineering, in particular to an excavation device for civil engineering foundation pit construction. Background Art

[0002] Excavation for civil construction is an important civil engineering construction process and an indispensable part of construction projects. Excavation for civil construction refers to the process of excavating earth in civil engineering. Earth excavation is one of the important processes in construction projects and is usually carried out when new buildings or infrastructure are built. Excavation projects usually include clearing, measuring and marking the land, and then using heavy machinery and equipment such as excavators and bulldozers to excavate the earth in order to build foundations or infrastructure.

[0003] At present, the excavators used for digging on the market have serious wear of the digging teeth after long-term use. If they are not replaced in time, the digging efficiency will be affected. Some replaceable digging teeth are complicated to replace, and it is inconvenient to replace individual digging teeth. The fixing effect is not good and they are easy to fall off. In addition, the reinforcement plate on the ordinary bucket is not easy to replace. If the reinforcement plate of the traditional bucket structure is damaged or worn, the entire bucket needs to be replaced or large-scale repairs need to be carried out, which is very time-consuming and labor-intensive.

[0004] For this reason, we propose a civil engineering foundation pit construction excavation device to solve the above problems. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the utility model are: the utility model;

[0015] By installing the bucket body and using multiple sets of digging tooth replacement components in coordination, specific digging tooth bodies can be adjusted and replaced according to actual conditions to maintain the best digging effect. The digging tooth bodies can be kept in good condition to ensure their optimal performance during the digging process, which will improve the working efficiency of the excavator, shorten construction time, and improve production efficiency. Replacing each set of digging tooth bodies separately can also achieve precise repairs. Only the damaged set of digging tooth bodies needs to be replaced without completely replacing the entire bucket or replacing the digging tooth bodies that do not need to be replaced. This effectively reduces maintenance costs, saves time and money, which not only extends the service life of the digging teeth, but also improves the overall performance and reliability of the excavator.
