Vertical shaft module and vertical shaft construction method using the same

The present invention relates to the construction field, and more particularly, to a vertical shaft module and a vertical shaft construction method using the same.

Vertical gang (vertical pit) refers to a kind of underground space structure that is constructed for excavation or operation in the construction of hydraulic tunnel of mining, road, subway and railway traffic tunnel, pumping station.

In the mining sector, the construction of large vertical shafts with a diameter of 7m or more for mining was active before the 1980s, but since the number and size of mines have been reduced, the demand for small and medium vertical shafts of about 3m for ventilation has been steadily increasing.

Vertical shaft extension in the mine ranges from less than 100m to more than 300m due to the location deviation of the veins.

In the water resources sector, demand for vertical shafts arises in the construction of a pumping station to generate electricity using water pumped during the daytime when the power usage is low and the power usage is high.

In the case of pumping power plant, the vertical shaft is extended because power is generated by using a high drop.

In addition, in order to effectively use the energy caused by the drop and maintain the stability of the vertical shaft, the vertical degree management is an important issue, so it acts as a condition for selecting the vertical shaft construction method.

When the bottom plate 135 is formed by the combination of the deck plate and concrete, the advantage that the construction is convenient and stable structure is added (15, 16).

When the plurality of pillar frames 141 are extended to the upper and lower sides of the stair hole frame 133, the second vertical shaft module 100B is installed in the inner region of the second waterproof layer 22 of the vertical hole 10, In order to install on the upper portion of the first vertical shaft module 100A, while combining the upper end of the cylindrical wall 110 of the first vertical shaft module 100A and the lower end of the cylindrical wall 110 of the second vertical shaft module 100B, Since the bottom of the pillar frame 141 of the second vertical shaft module 100B may be coupled to the top of the pillar frame 141 of the first vertical shaft module 100A, there is an effect of forming a stable vertical support structure as a whole. .

When the inner wall 142 is installed around the plurality of pillar frames 141 so as to cover and protect the stairs 140, safety against a fall, a fire, and the like is further enhanced.

For lifting of the vertical gang module 100, the lifting auxiliary device 300 of the following structure can be applied.

The lifting assistance device 300 includes a circular frame 310, a plurality of wires 320 connecting the circular frame 310 to the hook portion 30 of the crane, and a plurality of extensions extending downward of the circular frame 310. It takes the configuration with the connecting portion 330 of (Fig. 18, 19).
