Description

Vehicle type soft ground soil improvement device {Vehicle type soft ground soil improvement device}

The present invention relates to a vehicle-type soft ground soil improving device, and more particularly, a device for mixing soft ground soil and solidifying material is installed in a vehicle for convenient mobility, and the amount of solidifying material is adjusted according to the weight of the soft ground soil. It relates to a vehicle-type soft ground soil improvement device that collects and reuses enormous dust scattered in the process of mixing hardening material with soft ground soil.

In general, areas created by reclamation, dredging, or reclamation in areas such as coasts, rivers, and lakes not only form wetlands in which water and clay soil or water and mud are mixed on the surface, but also contain pore water in the ground. Therefore, in order to utilize such an area as an industrial or commercial area, the work of improving the soft ground soil to be suitable for site utilization must be preceded.

The solidification method of the surface soil of soft ground analyzes the soil quality of the soft ground distributed in the construction site, conducts structural review and mixing design, mixes the raw ground soil with solidified material in a fixed ratio to produce improved soil, and then compacts and cures It refers to a construction method that secures the required bearing capacity of the ground through the process.

To this end, the raw ground within 5m below the surface is collected with an excavator, put into a mixing device, mixed with powder solidified material in a separate stirring device at a predetermined ratio to produce improved soil, and compaction and curing processes using bulldozers and rollers will go through

In this way, the ground improvement is performed by mixing the solidifying material with the soft ground. Since it is performed at the installation site because a lot of heavy equipment is used, it is difficult to move after improving the soft ground soil in one place, so it is difficult to move it and then mix it with the solidifying material. The moving distance to the installation is long, the work efficiency is low, and it takes a lot of time to install the soil improvement equipment.

In addition, in the process of mixing the solidified material and the soft ground soil, a lot of the solidified material is scattered as dust. The scattered dust is not directly used for ground improvement and is discarded, but also deteriorates the working environment around the site and adversely affects the health of workers. In addition, when the ratio of hardening material and soft ground soil is mixed in a fixed ratio, the improvement effect is high and excessive consumption of solidifying material can be prevented. There are disadvantages in that the improved soft ground condition is lower than the target value and the use of solidifying materials increases because the ratio between the two is less accurate and does not mix properly.

In this way, the first agitator 120 having a first screw 121 for cutting and transporting the introduced soft ground soil is further included in the lower part of the first hopper 110, and rotation of the first screw 121 A control unit (not shown) that calculates the weight of soft ground soil according to the number, and the switch 133 determines the degree of opening according to the weight of the soft ground soil calculated by the first agitator 120. The opener 133 rotates or slides according to the operation of the motor, and the degree of opening is determined according to the amount of movement or rotation, so that the amount of solidifying material passing through can be adjusted.

The second hopper 130 is disposed next to the first hopper 110 in a side view, solidifying material is introduced from the top, and rises along the guide part 131 installed at the edge to unfold in a folded state. A corrugated pipe 132 is provided, and an opener 133 is provided at the bottom to adjust the input amount of the solidifying material by determining the opening rate according to the weight of the soft ground soil. The corrugated pipe 132 is bolted to the guide part 131 and is installed stably up and down along the guide part 131. It is opened and closed according to the determined opening rate. When the opening/closing device 133 is opened, a certain amount of solidification material injected into the second hopper 130 is introduced into the second agitator 170 installed below the second hopper 130.

At this time, as shown in FIG. 5, the guide part 131 has an upper part 131b of the guide part 131b provided to be flexible in the lower part 131a provided at the edge of the second hopper 130, so that the upper part of the guide part ( 131b) moves up and down and lifts the corrugated pipe 132.

On the other hand, a plurality of conveying pipes 151 are installed through the second hopper 130 or the corrugated pipe 132, and the filtering unit 150 disposed next to the second hopper 130 by the conveying pipe 151 And connected to the third hopper 160. Accordingly, when the solidification material is introduced into the second hopper 130, dust scattered along the plurality of transfer pipes 151 by the operation of the intake fan 141 of the dust collecting unit 140 is disposed in the third hopper disposed below the dust collecting unit 140. 160 and the filtering unit 150. The transfer pipe 151 connected to the filtering unit 150 in the second hopper 130 or the corrugated pipe 132 is branched into a plurality in order to smoothly transfer the dust scattered from the corrugated pipe 132 to the second hopper. 130 or the corrugated pipe 132, and then collected into one pipe and combined with the third hopper 160. In addition, the corrugated pipe 132 may have a narrow inlet to prevent scattering of dust. The transfer pipe 151 is connected to the corrugated pipe 132 or the second hopper 130 to suck in the scattered solidified material. In the present invention, since the second hopper 130 is a comprehensive code including the corrugated pipe 132, It is described that the transfer pipe 151 sucks the solidified material from the second hopper 130.

As such, the transfer pipe 151 connects the second hopper 130 and the third hopper 160, and is coupled with the second hopper 130 as a plurality of pipes.

The dust collecting unit 140 uses the suction force of the intake fan 141 to pull the solidified material scattered from the second hopper 130 to the filter body 154 via the transfer pipe 151 and the third hopper 160, , The solidified material that did not pass through the filter network 153 is stuck to the outside of the filter network 153, and the pressurized air supplied from the compressor 144 connected to the air passage 142 is filtered through the filter pipe 152 ), and the solidified material attached to the outside of the filter net 153 is detached by the shock generated from the pressurized air.

As shown in FIGS. 6 to 9, the filtering unit 150 collects and reuses dust scattered from the solidified material transported by the intake fan 141 of the dust collecting unit 140 along the transfer pipe 151. It includes a plurality of filter tubes 152 spaced apart from each other and having a comb-shaped support body, and a filter body 154 composed of a dense filter net 153 capable of filtering dust surrounding the outer circumferential surface of the filter tube 152. The filter tube 152 supports the filter net 153 by pressurized air supplied from the compressor 144, and the filter net 153 is supported by the solidifying material adhered to the filter net 153 by the intake fan 141. support In addition, a third hopper 160 is provided below the filtering unit 150, into which solidified material in the form of granules that has been agglomerated and then separated from the filter net 153 is introduced.

The air passage 142 of the dust collector 140 has one side connected to the compressor 144 for supplying pressurized air, and the other side connected to the intake fan 141 for sucking air. The air passage 142 is branched into a plurality of passage pipes 148 formed horizontally, and pressurized air is intermittently supplied to the filtering unit 150 to remove the solidified material clumped in the filter net 153 and at the same time an intake fan ( 141) to move the purified air passing through the filter net 153.

As shown in FIG. 7, the dust collection unit 140 uses the intake fan 141 to pull the scattered solidified material introduced into the third hopper 160 through the transfer pipe 151 to the filtering unit 150, and the The air that has passed through the filter net 153 in the filtering unit 150 moves outward along the air passage 142 through the open top of the filter tube 152 and is discharged to the air, and does not pass through the filter net 153. Unsuccessful solidifying material is entangled in the filter net (153). And, as shown in FIGS. 8 and 9, the dust collector 140 discharges pressurized air from the top of the filter pipe 152 to the inside through the air passage 142 and the connection pipe 143 using the compressor 144 When this is done, the filter net 153 disposed on the outer circumferential surface of the filter tube 152 is inflated, and the agglomerated solidification material in the form of granules attached to the filter net 153 is separated from the filter net 153 and is located at the bottom of the filter tube 152. It is put into the hopper 160. In the compressor 144, pressurized air is provided intermittently when the solidifying material adheres to the filter net 153 and the movement of air becomes difficult, and the intake fan 141 continues to rotate and introduce air, and pressurized air flows in Rotation can be stopped when

As such, the intake fan 141 is disposed on one side of the dust collection unit 140, is connected to the air passage 142, and is connected to a plurality of passage pipes 148 through a connection pipe 143 to filter the filter network (150) 153) is sucked in and discharged into the air. At this time, the air discharged into the air is in a somewhat clean state in which dust has been filtered through the filter net (153).

An inlet piece 152a having a wide upper part and narrowing toward the bottom and widening again is mounted on the upper part of the filter tube 152, and the pressurized air supplied from the compressor 144 is supplied from the upper part of the inlet piece 152a. Moving downward, the air passing through the filter net 153 moves from the lower part of the inlet piece 152a to the upper part. At this time, the lower end of the connection pipe 143 is arranged lower than the upper end of the inlet piece 152a to increase the supply efficiency of pressurized air to the filter body 154, and the air passing through the filter net 153 is easily passed through the air chamber. into furnace 142.

The air passage 142 connected to the compressor 144 is branched into a plurality of passage pipes 148 formed horizontally, and at the entrance of the passage pipe 148, the compressor 144 controls the pressurized air when providing pressurized air. The third valve 147 is installed to prevent the introduced pressurized air from being simultaneously supplied to all passage pipes 148 . Preferably, when pressurized air is supplied from the compressor 144, all passages except for one passage are closed so that pressurized air is provided only through the open passage, so that the solidified material attached to the filter net 153 has a strong impact to give In addition, when pressurized air is not supplied from the compressor 144, all third valves 147 are opened to introduce purified air. Between the air passage 142 and the intake fan 141, a first valve 145 is installed to block the inflow of pressurized air supplied from the compressor 144 to the intake fan 141, and pressurized by the intake fan 141. Make sure the air doesn't move.

The pressurized air supplied from the compressor 144 passes through the air passage 142 and the third valve 147, passes through the connection pipe 143 branched from the passage pipe 148, and pressurized air from the upper inside of the filter pipe 152 will emit Accordingly, pressurized air is introduced through the inlet piece 152a located at the upper part of the filtering unit 150 and discharged through the side of the filter tube 152, and gives a strong impact to the filter net 153 so that the filter net swells. As the 153 swells, the solidifying material in the form of granules attached to the filter net 153 falls off. That is, in the air passage 142, a plurality of passage pipes 148 extending above the filter pipe 152 are horizontally branched to supply pressurized air to the top of the filter body 152, and each passage pipe 148 A third valve 147 is provided to control the pressurized air supplied from the compressor 144, so that the pressurized air is supplied only to one passage pipe 148, so that the pressurized air supplied from the compressor 144 is simultaneously It is not supplied to two or more passage pipes 148, but is supplied to only one passage pipe 148. This operates each third valve 147 with a timer to supply the pressurized air intermittently supplied from the compressor 144 to only one passage pipe 148 to strengthen the impact in the corresponding filter network 153 and It can increase the fire escape rate.

10 and 11 are other embodiments of the dust collecting unit 140 . 10 shows the movement of air according to the operation of the intake fan 141 when pressurized air is not supplied from the compressor, and FIG. 11 shows the flow of pressurized air from the compressor 144 to any one passage pipe 148. It shows the moving path of the compressed air (straight line) and the purified air (dotted line) moving together with the solidifying material.

In this embodiment, the moving path 142 through which the pressurized air supplied from the compressor 144 moves is separated from the moving path of purified air by the intake fan 141. Since the pressurized air supplied from the compressor 144 is the same as the previous description, the description thereof will be omitted. The purified air passing through the filter body 154 moves to the purification chamber 149, which is a separate space outside the air passage 142, not the air passage 142, and is discharged to the atmosphere by the suction force of the intake fan 141. do.

At this time, the purification chamber 149 has a cover plate 149a blocking the upper portion of the filter body 154, an air passage 142 is formed on one side of the cover plate 149a, and the air passage 142 is horizontally Each branched passage pipe 148 and a third valve 147 installed at the inlet of the passage pipe 148 are included. However, since the inflow of pressurized air into the intake fan 141 is blocked, the first valve 145 blocking the movement of pressurized air from the air passage 142 to the intake fan 141 is not required. In this embodiment, the better the sealing power of the purification chamber 149 is, the better the purification capacity of the filter body 154 is, and thus more purified air can be discharged.

In this embodiment, the path in which the air purified from the top of the filter body 154 moves is different from the path in which the compressed air supplied from the compressor 144 moves. Most importantly, only pressurized air moves through the air passage 142 and purified air is not introduced. As shown in FIG. 11, the pressurized air supplied from the compressor 144 passes through the air passage 142, the passage pipe 148, the connection pipe 143, and the inlet piece 152a in order, respectively, and then the filter pipe 152 , is supplied to the filter net 153 and gives an impact to the filter net 153. In contrast, the air containing scattered solidified material moving by the suction force of the intake fan 141 passes through the filter net 153 and the filter tube 152 and passes through the connection tube 143, but not through the connection tube 143. It moves to the space between the and the inlet piece 152a, goes up to the cover plate 149a, and moves to the purification filter 149. The purified air does not enter the connecting pipe 143 because the suction force of the intake fan 141 does not reach the inside of the connecting pipe 143. In addition, since the intake fan 141 continues to operate, when pressurized air is supplied to any passage pipe 148 in which the third valve 147 is open, air cannot move from the outside to the inside of the filter net 153. The purified air does not pass through the filter body 154 having the passage pipe 148 to which pressurized air is supplied, and the purified air from the remaining passage pipe 148 to which pressurized air is not supplied continues to the purification chamber 149. can move

On the other hand, in the filtering unit 150, the filter body 154 is composed of a plurality of rows and columns, and fixing means (not shown) for fixing each other are provided between the filter tubes 152 arranged in rows and columns. When air is introduced into and discharged from 152, a plurality of filter tubes 152 are fixed so as not to move by a fixing means (not shown).

In the filter body 154, the filter net 153 is disposed only on the side of the filter pipe 152, and the filter pipe 152 is formed in a form in which the upper surface is open and the lower surface 152b is closed, from the top to the inside. When pressurized air is introduced into the furnace, the pressurized air spreads only to the side surface.
