Below the aggregate carrying-in section 5, a rectangular silo section 6, an aggregate separation plant section 7, and a transfer section 8 are separated by a partition wall 9.

The silo section 6 and the aggregate separation plant section 7 are laterally adjacent to each other, and the transfer section 8 is defined by a partition wall 9 over one end of both.

Furthermore, the silo section 6 is divided into eight parallel aggregate silos 11 by partition walls 10 connected to the continuous underground W3 and the partition walls 9 and arranged in a grid pattern, and a bottom plate 12 having a supply port.
The lower side partitioned by is used as the installation section 13 for the transport equipment.

At the upper opening of each aggregate silo 11, a grating 14 whose grid size differs depending on the required silo is provided.This grating 14 and a floor slab 15 provided at the upper opening of the aggregate separation plant section 7 allow the above-mentioned The floor of the aggregate carrying-in section 5 is constructed.

Further, a cement silo 16 is installed above the aggregate separation plant section 7 and the transfer section 8.

The bottom plate 17 of the underground structure 1 is anchored to the ground by an earth anchor 18, thereby preventing the underground structure 1 from floating up due to the pressure of groundwater in the surrounding ground.

Belt conveyors 19 and 20 are horizontally disposed on the installation section 13 of the conveying equipment and on the bottom plate of the aggregate separation plant section 7, facing the belt conveyor 21 of the transfer section 8. It is now possible to send out lumber and separated aggregate.

Reference numeral 22 denotes a storage section for the batcher plant 2, which is provided in contact with the aggregate separation plant section side of the underground structure 1, and the batcher plant 2 and the ready-mixed concrete tank 23 are arranged side by side within the container. Also, in the underground shunting yard 4, there is a ready-mixed concrete stand 24 connected to a ready-mixed concrete tank 23.
A vertical conveyor device 25 is provided between the batcher plant 2 and the transfer section 8 and is connected to the belt conveyor 21 of the transfer section 8.

Reference numeral 26 denotes a car wash, which is installed in a part of the underground train yard 4 adjacent to the aggregate separation plant section 7, and the aggregate and water generated by washing are passed through a treatment device 27 installed in the aggregate separation plant section 7.
It is then separated and made available for reuse.

Reference numeral 28 denotes a side road, which is laid from the road to the underground train yard 4 with earth retaining walls 29 provided on both sides that also serve as soundproof walls.

Note that 30 is an office building above the underground train yard 4.

In such an underground factory facility, a large truck can drive into the underground aggregate delivery section 5 from the side road 28 and unload the aggregate on the loading platform onto a designated aggregate silo 11. The aggregate is passed directly from the truck through the grating 14 to the aggregate silo 1.
It will be put into 1.

In addition, using the grating 14, large foreign objects and aggregates can be screened out, and impurities such as iron pieces can be screened out.
Although not shown in the drawings, it can be removed by a magnetic separator provided on the belt conveyor 19.

The aggregates in each aggregate silo 11 are sent to the transfer section 8 by the belt conveyor 19 according to size as necessary, and then transferred to the belt conveyor 21 and sent to the vertical conveyor system @25.

Further, in some cases, separated aggregate is sent out from the aggregate separation plant section 7 by the belt conveyor 20, and is sent out together with the aggregate from the aggregate silo 11 in a shared state.
A vertical conveyor system 25 delivers the aggregate to the upper part of the batcher plant 2, where it is weighed in the usual manner. Further, cement is supplied to the batcher plant 2 from the cement silo 17 via another route, and after being weighed, it is mixed with the above-mentioned aggregate in a mixer to form ready-mixed concrete.

This ready-mixed concrete is stored in a ready-mixed concrete tank 23 from the batcher plant 2, and is further transferred to a ready-mixed concrete stand 23 in an underground train yard 4 by a concrete pump.
It is pushed up and poured into the drum of a mixer truck.

[Effects of the Invention] As described above, the present invention provides the working sections of the aggregate import section, the silo section, the aggregate separation plant section, and the transfer section inside an underground structure made of concrete, thereby creating an underground train yard. Since the plant was constructed underground along with the batcher plant and the factory equipment was removed from above ground, the large area of the factory site can be effectively used for other purposes.

In addition, since all of the factory equipment is underground, the noise generated when unloading aggregates does not leak outside, and aggregates can be directly supplied to the silos, so there is no need for conveyors or other transport equipment. becomes.

Furthermore, there is an underground structure with an internal aggregate silo and a batcher.
Since the plant and the plant are located adjacent to each other underground, and both are connected by a conveyor device, the aggregate delivery path can be shortened, and the underground structure divided by partition walls can be further divided by partition walls.
By forming a large number of aggregate silos, the cost is lower than when constructing individual silos on the ground, the continuous underground wall maintains water tightness, and the partition wall supports the surrounding wall. It also has many advantages, such as being sturdy.
