Detailed Description of the Invention

[0001]

[Field of Industrial Application] The present invention is the full amount of mud in a muddy water separator for treating muddy water and industrial wastewater in a muddy water excavation method adopted in foundation construction, cast-in-place piles, underground wall construction, etc. It relates to a sensing device.

[0002]

2. Description of the Related Art The muddy water excavation method is a low vibration and low noise method, which is a cast-in-place pile, underground continuous wall, muddy water shield work,
Widely used in muddy water propulsion work. For example, there are earth drill construction method, reverse circulation construction method, and BH construction method for cast-in-place piles, and bucket type and rotary type construction methods are carried out on the continuous underground wall using the mud excavation method.

In this mud drilling method, various mud such as natural mud, bentonite mud, polymer mud, etc. are used as a stabilizing solution for a drill hole, as a transport fluid for excavated soil, and as a replacement fluid for fresh concrete when pouring fresh concrete. Cage,
In addition, it is also used for cooling excavators and preventing the discharge of groundwater. Therefore, it is known that the control of mud used during construction has a great influence on the quality, construction period, cost and safety of concrete.

The properties of such muddy water are generally controlled so that the viscosity, the specific gravity, the amount of filtered water, the thickness of the mud film, the sand content, and the PH are below predetermined values as indexes. Above all, in order to ensure construction quality, it is important to keep the specific gravity of mud water as low as possible while the drill hole is stable. Normally, the specific gravity of muddy water is preferably 1.2 or less when excavating and 1.1 or less when placing fresh concrete. And
If the specific gravity rises beyond this range, the quality of muddy water deteriorates, the excavation efficiency decreases, and further, when fresh concrete is laid, slime is caught, which hinders construction management and quality control. Therefore, it is required to remove as much as possible soil particles such as slime dissolved in muddy water.

Therefore, as a treatment for removing the soil particles in the muddy water to reduce the specific gravity, natural sedimentation or a mechanical device such as a cyclone was used. The specific gravity reduction effect was not always sufficient. That is, for the above-mentioned treatment for removing slime in mud water, an apparatus combining a vibrating screen and a liquid cyclone is generally used, and the classification point is about 74 microns. This classification point means that the ratio of underflow and overflow is 50%: 5
The particle size is 0%, and 50% of the fine sand content is included in the overflow in the earth and sand separating apparatus in which the vibration type sieve and the liquid cyclone are combined. Therefore, when the conventional equipment cannot remove soil particles of 74 microns or less, when excavating the ground containing fine sand, silt, and clay, these soil particles remain in the muddy water, reducing the specific gravity of the muddy water. I couldn't. Therefore, it has been difficult to reduce the specific gravity of the used mud water whose specific gravity has increased and reuse it.

[0006]

Therefore, during the construction of the muddy water excavation method, a part of the muddy water which cannot be used due to accumulation of soil particles due to the excavated soil and an increase in specific gravity is adjusted by a new liquid. The way is done. That is, the muddy water whose specific gravity has increased due to use is discarded.
However, when the muddy water is discarded and diluted with a new liquid, it takes time to replace the muddy water, which affects the construction period, and a new liquid cost is required.

In addition, when performing various construction works, surface water,
Groundwater, rainwater, etc. are mixed with earth and sand, cement, etc. to generate turbid water as industrial wastewater. For example, muddy water associated with tunnel construction, wash water associated with aggregate production, muddy water associated with rainwater during construction, muddy water associated with dredging and land reclamation, waste water from a batcher plant, muddy water associated with concrete placement, grout. , Turbid water associated with boring, oil-containing wastewater leaking from construction machinery, iron-containing wastewater associated with water changes, etc.

[0008] Waste sludge is "sludge" of industrial waste.
Therefore, from the viewpoint of preventing environmental damage, it is necessary to properly treat the wastewater before it is discarded, and also to treat turbid water as industrial wastewater from the viewpoint of preventing water pollution. Therefore, there is a problem that the treatment of waste mud water and industrial waste water is complicated, and the treatment cost thereof rises.

Further, as a dehydration treatment for treating waste mud, a means for reducing the amount of "sludge" of industrial waste by dehydrating the waste mud by using a dehydrator using a filter cloth has been studied. However, since the particles of the waste mud are fine, the filter cloth is likely to be clogged, and the dewatering capacity is reduced in a short time, so it is difficult to effectively reduce the amount of the waste mud. Met.

[0010] Therefore, the applicant is a vertical type muddy water separator for removing soil particles from muddy water used in the muddy water excavation method to reduce the specific gravity for reuse, and for dewatering waste muddy water and various industrial wastewater. Are offered for use. This muddy water separator has a fixed casing with a discharge port and a muddy water supply port, a cylindrical non-walled basket rotating inside the fixed casing, and a crossing center of arms arranged in a cross shape in the annular bottom of the basket. And a rotary drive shaft which is fixed to the portion and rotatably suspends the basket in a fixed casing. Then, by rotating the rotary drive shaft at a high speed and supplying muddy water into the basket from the center of the fixed casing during rotation, sediment particles are deposited as muddy soil on the inner peripheral wall of the basket to separate solid-liquid. . Further, when the mud adhesion capacity of the basket reaches the limit, the solid-liquid separation work is temporarily stopped and the mud is scraped off.

In the above work, it is necessary to detect whether or not the mud adhered capacity has reached the limit, that is, whether or not the mud has reached the limit, but the conventional mud water separator detects this. There was no means, and the experience of skilled workers and time processing were performed exclusively. Therefore, if the scraping work is performed after a certain period of time, the basket may not be full, or the scraping work cannot be performed even when the basket is already full, and the muddy water is drained as it is. May occur.

Therefore, the present invention solves the problem of such a muddy water separator, and when mud reaches the full amount, it is immediately sensed and automatically scraped. It is an object of the present invention to provide a full amount sensing device that can be used.

On the other hand, FIG. 2 shows a manual type full amount sensing device 70 which is a modification of the full amount sensing device 40. The full amount sensing device 70 includes a manual sensing lever 41 and a sensing rod 42 that is rotatably supported by the lid of the fixed casing 1 and is rotatably driven by the sensing lever 41. The lower portion of the sensing rod 42 is formed with a bent portion 42a that is bent in the direction of the basket 9 at approximately 90 degrees, and the tip end of the bent portion 42a is formed in the basket 9.
It is set up so that it can contact mud that is consolidated inside.

Further, as shown in FIG. 1, a compressor 51 is provided outside the fixed casing 1, and a tube body 53 connected to an air hose 52 led from the compressor 51 is provided on a side portion of the shaft casing 5. The air nozzle 54 is fixed and faces the soil discharge port 12. Therefore, when the mud adhered to the inner peripheral wall of the basket 9 is scraped off, if air is blown from the air nozzle 54, the discharge of the mud is promoted.

According to such a muddy water separator 20, muddy water or various industrial wastewater used in the muddy water excavation method is introduced into the muddy water supply port 3, the basket 9 is rotated at 700 to 800 rpm, and the muddy water introduced into the muddy water is 400 to 400. By applying a centrifugal force of 600 G, the soil particles are instantly settled and consolidated in the basket 9 at the classification point of 10 μm. The treated water overflows from the upper part of the basket 9 and is drained from the drain port 30 and is sent to a treatment liquid tank (not shown) to be reused as a predetermined drainage treatment or stabilizing solution.

It is assumed that the inside of the basket 9 is filled with mud during the above operation. Then, the mud 45 becomes a plurality of sensor plates 19 and 19 shown in FIGS.

Then, the rotary switch 15 integrally fixed to the operating shaft 18 rotates against the biasing force of the spring means 21, and the limit switch 16 is switched from off to on. The ON / OFF signal of the limit switch 16 is transmitted to the drive source of the rotary drive shaft 4, and the drive source causes the drive source to rotate at a low speed, for example, 100 to 300 r.
The muddy water is dropped to pm and the supply of muddy water from the muddy water supply port 3 is stopped, and the mud soil 45 compacted based on the action of the scraping device 60 in the next stage is scraped.

That is, the bracket 37 and the scraping teeth 38 are rotated based on the rotation of the scraping arm 36 which constitutes the scraping device 60.
Is shown in FIG. 7 when muddy water is being supplied into the basket 9.
As shown by the phantom line in FIG. During the scraping operation, the hydraulic cylinder (not shown) is operated to rotate the scraping arm 36 via the bracket 35a, and as shown by the solid line in FIG.
Move in a direction that bites into the compacted soil particles. Then, soil particles compacted by the rotating force of the basket 9 are scraped off by the special tip 38a of the scraping tooth 38, guided by the soil discharging plate 39, and discharged from the soil discharging port 12.

When the mud soil 45 adheres to the inner edge of the soil discharge port 12 by the inertial force, a synthetic force of the moment of the arm 7 is formed to give a downward moving force to the mud soil 45, and the air nozzle 54 blows air. The muddy soil 45 is prevented from adhering by spraying. The scraped mud 45 passes through the soil discharge port 12, is discharged from the discharge port 2, and is discharged to the outside by a conveyor device or the like. When the scraping off of the mud 45 is completed, the rotation switch 15 is returned to the normal position by the spring means 21, and the rotation switch 15 and the limit switch 16 are returned to the non-contact state.

Assuming the behavior of muddy water droplets or droplets thrown into the basket 9 during such an operation, the droplets or droplets are first arranged in the vicinity of the tip of the sensor plate 19 above the malfunction preventing mechanism 50. Collides with the malfunction prevention sensor 28. Since the malfunction prevention sensor 28 is rotatably attached to the fixed shaft 22 near the tip of the sensor plate 19, even if a water drop or a droplet collides, it spins idle to absorb the collision force of the water droplet or the droplet. , Operating shaft 18
There is no turning. Therefore, the actuating shaft 18 is prevented from erroneously rotating due to collision energy such as water droplets even if the amount of mud is not full, and malfunction of the full amount sensing device 40 is prevented. When the mud comes into contact with the malfunction prevention sensor 28, the working shaft 18 is rotated by the pressure of the mud without idling, and the full amount sensing device 40
Activate

On the other hand, in the case of the manual type full amount sensing device 70 shown in FIG. 2, when an operator turns the sensing lever 41 rotatably supported by the lid of the fixed casing 1, When the sensing rod 42 is driven to rotate, the tip of the bent portion 42a bent from the lower side of the sensing rod 42 toward the basket 9 comes into contact with the mud 45 compacted in the basket 9 and is transmitted to the worker as resistance. To be Thereby, the worker can detect that the mud 45 has reached the full state and operate the scraping device 60 based on the immediately performed operation mode to remove the compacted mud 45.

As described above, according to the present embodiment, it is possible to automatically detect that the basket 9 in the muddy water separator 20 has reached the limit of the mud adhering capacity and shift to the mud scraping operation. You can Further, by making the basket 9 a non-peripheral peripheral wall, it is possible to smoothly separate the mud water having any specific gravity and viscosity. The muddy water treated by the muddy water separator 20 is almost composed of soil particles of 10 microns or less, and the soil particles of 10 microns or more are collected in the basket 9. Moreover, it has an advantage that the whole structure is simplified and the manufacturing is easy.

[0036]

As described in detail above, according to the muddy soil full amount detecting device in the muddy water separator of the present invention,
A certain amount of mud is placed on the non-perforated wall of the basket inside the muddy water separator.
There when adhered, one of the plurality of sensor plate rotational force of the basket in contact with the mud is transmitted to the rotary switch, limit switch is switched from off to on the supply mud is stopped Rutotomoni basket can and this <br/> migrating low <br/> speed rotation, and the the scraping work of compacted mud. Therefore, it is prevented to continue the work without noticing that the basket in the muddy water separator has reached the limit of the muddy soil adhesion capacity, and the treated water whose specific gravity has not been sufficiently reduced due to deterioration of muddy water separation performance is treated as muddy water. It will not be supplied as mud used in the excavation method, nor will treated water that has not been sufficiently removed of soil particles be discharged. Especially, it is possible to maintain the specific gravity of the mud water used as a soil stabilization liquid in the mud excavation method used in construction work, foundation work associated with civil engineering work, underground continuous walls, cast-in-place piles, or shield construction methods. Great effect.

Further, by providing the malfunction preventing mechanism of the operating shaft, even if muddy water droplets or splashes collide with the malfunction detecting sensor constituting the malfunction preventing mechanism, the malfunction detecting sensor idles and the collision force of the water drops or splashes. Is absorbed and the operating shaft is not rotated. Therefore, even if the amount of mud is not full, the actuating shaft does not rotate accidentally due to collision energy such as water droplets, and malfunction of the full amount sensing device is prevented. When the mud comes into contact with the malfunction detection sensor, the operation shaft is reliably rotated by the pressure of the mud without slipping, and the full amount can be reliably sensed. In addition, the muddy water separator is equipped with a manual full-volume detector, which allows the operator to rotate the sensing lever to consolidate the tip of the bent portion formed on the lower side of the sensing rod into the basket. Since it contacts with the mud that has been created and is transmitted to the worker as resistance, it is possible to detect that the mud has reached a full state with an extremely simple structure, and immediately activate the scraping device to consolidate the mud. Can be removed.
