Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a construction engineering construction shaft. Background Technique

[0002] In some underground projects, in order to ensure the normal progress of underground projects, it is necessary to assist through shafts to ensure the transportation of materials. The shafts used in construction engineering are all dug and used on-site. Some wells are relatively deep, and after excavation, construction workers need to go down the well for masonry. Therefore, in general, the upper opening of deeper wells will be dug with a larger and wider diameter to avoid collapses and other situations, and a gentle slope also needs to be designed according to the depth. How to avoid potential safety hazards is an issue that needs to be constantly noted. Although the currently used construction engineering shafts can meet the normal use requirements, they still have defects in the actual use process;

[0003] For example, a construction engineering construction shaft provided in the authorized publication number CN215718750U. This patent is designed with a first protective sleeve, a second protective sleeve, a threaded rod, and a threaded sleeve. The device is placed into the dug shaft, and then the position is adjusted and the threaded rod is rotated, so that the threaded rod and its threaded sleeve generate a threaded rotation, so that the second protective sleeve slides vertically downward in the first protective sleeve, thus avoiding safety hazards such as collapses during the underground construction of the well by the operator;

[0004] However, the ventilation effect inside the shaft is not ideal. When the temperature inside the shaft is relatively low or high, it is not convenient to adjust the temperature inside the shaft. It is more uncomfortable for the staff to construct inside the shaft and needs to be improved. Therefore, a construction engineering construction shaft is now proposed. Summary of the Invention
