[Prior Art] Factory equipment, usually called a ready-mixed concrete plant, is comprised of a cement silo, an aggregate silo, and a patcher plant, and the aggregate is conveyed to the upper part of the patcher plant by a belt conveyor device. Cement, aggregates, admixtures, water, etc. are measured in the patcher plant, and the ready-mixed concrete produced by mixing with the mixer is directly fed into the drum of the mixer truck from the bottom of the patcher plant.

[Problems to be solved by the invention] Such ready-mixed concrete factory equipment requires silos for each size of aggregate, and requires a large site due to the frequent entry and exit of mixer trucks and large trucks. Due to the noise caused by factories, it is considered difficult to construct factories near urban areas.

Additionally, existing factories are being forced to relocate due to land redevelopment in geographically convenient locations.

This invention was conceived from the above-mentioned circumstances, and its purpose is to construct all of the factory equipment underground, and the above-ground part can be used as an office building etc. that does not require a large land area, and the noise level of the factory is extremely low. The objective is to provide underground ready-mixed concrete factory equipment with a new configuration.

[Means for Solving the Problems] The feature of this invention according to the above-mentioned object is that the working sections of the aggregate import section, the silo section, the aggregate separation plant section, and the transfer section are provided inside an underground structure made of concrete. The SQ is placed underground together with an underground shunting yard, and a patcher plant is installed underground in stages from the transfer section of the underground structure to the underground shunting yard above, and for each processing section.

The above-mentioned underground structure has an aggregate loading section in the upper part connected to the underground shunting yard, and below it, the silo section, the aggregate separation plant section, and the transfer section are separated by partition walls, and the above-mentioned silo The section consists of a required number of aggregate silos with an upper opening partitioned by partition walls arranged in a lattice pattern and a bottom plate with a supply port.

In addition, the aggregate separation plant section and the transfer section also serve as a housing section for the cement silo, and the surrounding wall of the underground structure is composed of a continuous underground wall.

[Function] In the underground ready-mixed concrete factory facility having the above configuration, a large truck can be driven into the aggregate delivery section from the underground yard and aggregate can be directly dropped into each aggregate silo by size.

The aggregate in each silo is sent from the bottom of the silo to the transfer section by a conveyor on the bottom plate, and in some cases, is transferred to a conveyor device together with the aggregate from the aggregate separation plant section, and then transferred to a patcher installed diagonally in the ground. It is sent to the plant, where the cement, aggregate, water, etc. from the cement silo are weighed and mixed in stages from below as usual.

Furthermore, the peripheral wall of the underground structure, which is composed of a continuous underground wall, has excellent water-stop properties, and the partition walls that partition the aggregate silos function as supports for the underground continuous wall.

The present invention will be explained in more detail below with reference to illustrated embodiments.

[Example 1 1 in the figure is a concrete underground structure constructed underground, consisting of a container with a rectangular planar cross section and a continuous underground wall 3 in one section of the underground operation IrI field 2. .

Moreover, the underground structure 1 has an aggregate carrying-in part 5 connected to the underground rail yard 2 at the upper part, and a rectangular silo part 6 and an aggregate separation plant part 7 below the aggregate carrying-in part 5. Each working section of the section 8 is divided 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 gap 19 over one end of both.

Furthermore, the silo section 6 is divided into eight parallel aggregate silos 11 by partition walls 1o connected to the continuous underground wall 3 and the partition wall 9 and arranged in a lattice pattern, and the lower side partitioned by a bottom plate 12. is used as the installation section 13 of 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.

On the aggregate separation plant side of the underground structure 1, the patcher plant accommodating section 4 is installed diagonally toward the underground shunting yard 2 along with the transfer section 8, and a batcher plant 16 is installed therein. Upper mixer unit @15a, measuring device 16b,
The arrangement of the supply devices 16c is reversed from the usual order and is installed in stages. In addition, each device is a belt conveyor 17.18
part 1 of the lowest conveyor belt 18
8a extends horizontally to the transfer section 8.

The bottom plate 19 of the underground structure 1 is anchored to the ground by an earth anchor 20, thereby preventing the underground structure 1 from floating up due to the pressure of groundwater in the surrounding ground.

In addition, the installation part 13 of the conveyance unit and the aggregate separation plant part 7
Belt conveyors 21, 22 are arranged horizontally on the bottom plate of the conveyor belt 21, 22 facing the belt conveyor 18a of the transfer section 8, so that aggregates and separated aggregates can be delivered to the belt conveyor 18a. ing.

Reference numeral 23 denotes a car wash facility, which is installed in a part adjacent to the above-mentioned aggregate separation plant section 7 of the underground car handling facility [4], and aggregates and water generated by washing are passed through a processing device 24 installed in the aggregate separation plant section 7.
It is then separated and made available for reuse.

In addition, 25 is a cement silo, and aggregate separation plant section 7
and installed above the transfer section 8. 26 is an office building above the underground train yard 4.

In such an underground factory facility, a large truck can be driven into the aggregate delivery section 5 from the underground vehicle handling vA2, and the aggregate on the loading platform can be lowered onto a predetermined aggregate size 011, and the aggregate can be directly delivered from the truck. The aggregate is then fed into the aggregate silo 11 through the grating 14.

In addition, the grating 14 can be used to screen out large foreign objects and aggregates, and to remove impurities such as iron pieces.
Although not shown in the drawing, it can be removed by a magnetic separator provided on the belt conveyor 21.

The aggregate of each silo or the aggregate of the aggregate separation plant section is transported to the belt conveyor 21, 22 according to size as necessary.

The concrete is transferred to the mixer @ 16a, where it is mixed with weighed cement supplied from the cement silo 25 via another route to become ready-mixed concrete.

This fresh concrete is pushed up by a concrete bong into the concrete hopper 16d of the underground train yard 2, and poured into the drum of a waiting 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 within an underground structure made of concrete, so that they can be installed together with the underground train yard. The patcher plant is installed underground, extending from the transfer section of the underground structure to the underground train yard above, and the patcher plant is installed in stages for each treatment section, replacing all of the equipment that previously required a large installation area. Since the above ground was removed from the ground, the above ground of the factory site can be effectively used for the purpose of the factory.

In addition, since many aggregate silos are located underground, the noise caused by unloading aggregate does not leak outside, and the supply to the silos can be carried out directly, eliminating the need for conveyors or other transport equipment. .

Furthermore, since the patcher plant is installed diagonally underground to reduce its height, the excavation depth is shallower than in the case where the patcher plant is installed vertically, and the cost required for excavation work can be reduced.

Moreover, since the aggregate silo is also formed within an underground structure partitioned by partition walls and further partitioned by partition walls, the excavation depth can be shallower than in the case where the aggregate silo is installed, and the cost required for excavation work can be reduced.

Furthermore, since the aggregate silo is formed within an underground structure divided by partition walls and further partitioned by partition walls, the cost is lower than when constructing individual silos above ground, and the continuous underground wall provides water-tightness. It has many advantages, such as being durable and sturdy since the partition wall also serves as a support for the surrounding wall.
