Description

Technical Field

[0001] The utility model relates to the technical field of vertical shaft construction, in particular to a vertical shaft shaft segment ring which is lightweight, low-cost and easy to connect. Background Art

[0002] Vertical shafts are widely used in the ventilation of underground pipelines in the fields of coal, subway, etc. and the entry and exit of personnel and materials. After the vertical shaft is completed, it is necessary to use concrete, brickwork and other methods to make the shaft to prevent the shaft wall from collapsing. In order to improve construction efficiency, most of the existing shafts are connected by multiple stacked segment rings. In order to improve compressive strength, the segment rings close to the bottom of the shaft are mostly made of steel box girders cast concrete, which can reduce the thickness while ensuring strength. However, this type of segment ring has a heavy self-weight and high cost. The segment rings close to the wellhead have a shallow depth and require relatively small compressive strength. Continuing to use the segment rings made of steel box girders cast concrete is less economical. Therefore, most of these segment rings are made of steel cage cast concrete, which reduces their own weight and reduces costs. However, since the top and bottom of this type of segment ring are concrete surfaces, it is difficult to use welding and other methods to connect them after stacking, and the connection is difficult.
