Description
Technical Field
[0001] The utility model relates to the technical field of vertical shaft construction, in particular to a temporary covering structure used for vertical shaft construction. Background Art
[0002] During shaft construction, the safe sealing of the shaft opening is crucial for ensuring smooth construction and personnel safety. Traditional shaft sealing methods often employ simple wooden planks or stones for temporary shielding. This method is not only unstable but also prone to movement or collapse due to external forces, such as wind or accidental contact, posing a safety hazard to construction workers. Furthermore, traditional sealing methods often fail to provide effective access to and from the shaft, forcing construction workers to rely on complex auxiliary equipment when entering and exiting the shaft. This is not only inefficient but also increases construction difficulty and cost.
[0003] With the continuous advancement of shaft construction technology, the requirements for wellhead covering structures are also increasing. Modern shaft construction not only requires the covering structure to be firmly fixed to the wellhead to prevent collapse and accidents, but also requires convenient and safe up and down-well passages so that construction personnel can work efficiently and safely. However, most of the shaft covering structures currently on the market have problems such as complex design, inconvenient installation, high cost of use or insufficient safety, which are difficult to meet the needs of modern shaft construction. Therefore, in response to the above technical problems, a temporary covering structure for shaft construction is proposed herein. Utility Model Content
