Description

Technical Field

[0001] The utility model relates to the technical field of vertical shafts, in particular to a prefabricated square vertical shaft mold. Background Art

[0002] A vertical shaft is an upright well-shaped pipe on the cave wall. It is actually a collapsed funnel, and its plane profile is square, long or irregularly circular. Vertical shafts are widely used in water intake, water diversion, ventilation, slag removal and air replenishment in water conservancy and hydropower projects. Vertical shaft construction has the characteristics of small footprint and little interference with surrounding construction. However, vertical shaft construction has small space, long construction period, many climbing and edge operations, and inconvenient passage, resulting in prominent safety risks in vertical shaft construction.

[0003] At present, in the process of shaft construction, it is necessary to dig a well hole first, and then pour concrete on the well wall. However, this construction method is not only troublesome and wasteful, but also easy to generate noise and dust during on-site construction, which has a great impact on the environment. Moreover, the quality of on-site pouring is difficult to guarantee, and the construction period is long. For example, a prefabricated square shaft mold with authorization announcement number: CN214273640U is used to prefabricate and pour the inner wall of the shaft through the prefabricated square shaft mold, and then directly install it on the use site. Although it is easy to install, this shaft mold is greatly affected by the weather. If the air humidity is high, the prefabricated shaft takes a long time to form, which affects the construction progress of the construction site. At the same time, the prefabricated shaft formed by this shaft mold will have air inside, which affects the quality of the shaft. Utility Model Content
