Description

[0002] Vertical shafts are widely used in the ventilation of underground pipelines in the fields of coal, subway, etc. and for 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 made of prefabricated pipe rings. Traditional pipe rings are mostly made of reinforced cages cast in concrete, and the compressive strength of concrete is relatively low, so the wall thickness can only be increased to meet the strength requirements of the shaft. Under the same inner diameter, the outer diameter of the thick-walled pipe ring is larger, so the excavation diameter of the vertical shaft needs to be increased, which will greatly increase the engineering workload of the vertical shaft construction. At the same time, after the shaft is made, the inner and outer walls are both concrete surfaces, and the water-proofing property is relatively weak. When installing other accessories on the inner wall, it is necessary to drill holes and anchor them, which is not convenient. Utility Model Content
