JP4443329B2 - Garbage disposal method at waste disposal site - Google Patents

Description

  The present invention relates to a garbage disposal method for realizing volume reduction of garbage at a waste disposal site.

  Among industrial wastes, waste (garbage) that is not reused is dumped in a waste disposal site, and dumping is simply performed on the previous garbage, and the garbage is sequentially stacked. If left unattended, there is no reduction in volume other than natural compression by its own weight. For this reason, when the disposal site is full, another disposal site must be found.

  Therefore, a waste volume reduction process at a waste disposal point has been proposed. For example, Japanese Patent Application Laid-Open No. 7-16555 (Patent Document 1) discloses that a weight is dropped on accumulated waste to compress the waste with high density.

  Further, in JP-A-10-102475 (Patent Document 2), the tip portion crosses the cross and the center portion is most protruded, and is deposited and discarded by a compression rod provided with a cutting blade in a state of being retracted away from the center portion. Means for making a hole in an object and putting waste into the hole is disclosed.

  Further, JP-A-10-272432 (Patent Document 3) discloses that excavation and drilling without drilling is performed using a excavated soil and sand compacted auger provided with a trowel portion provided so as to spirally rise in the excavation rotation direction. After that, while the auger is inserted into the hole, it is rotated backwards and pulled out, dust is put in from the hole mouth, and dropped to the bottom of the hole to be consolidated into the hole wall with the iron part, and the rest is holed. A means for reducing the volume of dust sequentially deposited on the bottom is disclosed.

  Japanese Patent Laid-Open No. 2001-286843 (Patent Document 4) uses a drilling device comprising a casing provided with a compacting iron on the circumferential surface and a drilling rod having a drilling head that passes through the casing and protrudes from the tip. In addition, there is disclosed a dust volume reducing means that performs excavation-free excavation with a compacting iron of the casing, puts surface layer dust into the casing while leaving the casing, and then pulls out the casing.

Japanese Patent Laid-Open No. 7-16555. JP-A-10-102475. Japanese Patent Laid-Open No. 10-272432. JP 2001-286843 A.

  It is known to form a void by compressing dust as described above, and to reduce the volume of dust by throwing surface layer dust into the void, and in particular, excavating dust to a hole wall to compress the drilling waste, and no discharge drilling hole And forming the voids (hereinafter referred to as “volume reduction method using consolidated holes”) are also disclosed in Patent Documents 3 and 4.

  However, the conventional volume reduction method using the consolidation hole is not necessarily the optimum method. For example, in the construction method described in Patent Document 3, since the backfilling of the dust is due to the drawing process by the reverse rotation of the excavating rod, the excavation work and the backfilling work are basically performed by one excavator. Considering the work of collecting garbage for backfilling, it is not always an efficient method. Furthermore, there is a possibility that the hole wall that has been compacted may be collapsed during the above-described extraction (reverse rotation of the auger).

  In addition, as described in Patent Document 4, the casing itself is used for forming a compaction hole, and after the garbage is backfilled, the casing is pulled out, so that the excavation head needs to excavate and pulverize the dust. And complicated operations and operations such as simultaneous rotation operation of the excavation rod and removal of the excavation rod are required. Furthermore, if the casing is not immediately pulled out after the surface dust is put into the casing, the casing's compacting iron becomes a pulling resistance, which is subject to time constraints. Moreover, since the filling of the dust into the casing is performed with the excavation rod left, a balance between the amount of dust input and the amount of extraction of the excavation rod is required, and the operation itself becomes complicated.

  Therefore, the present invention proposes a volume reduction method using a compacted hole in a new waste disposal site that realizes simplification of equipment used and simplification of work.

Disposal Method in waste disposal sites according to the present invention, both when provided with iron surface from the core periphery to the core of the appropriate length to the drilling diameter, a plurality of compaction trowel portion forming a jet hole in the appropriate positions week to set, Rutotomoni provided as tapered tip angle the tip portion is an acute angle, from the tip portion to the consolidation iron part circumferential設箇plants, the spiral vane gradually becomes large diameter up to the drilling diameter corresponding to the tapered Using an auger provided with a high-pressure air supply unit that communicates with the injection hole, forming a no-discharge drilling hole while performing air injection from the injection hole at a dust accumulation location, and then pulling out the auger In addition, a casing having a smooth outer peripheral surface is put into the excavation hole, and the casing is pulled out while charging or filling the casing with or after filling.

Therefore in order to practice the can consolidation hole in Ho穿, drilling while air injected from the injection holes Thus also formed in appropriate positions of the compacted iron portion in the rotation press-fitting of the auger without crushing the garbage, compaction trowel to prevent dust from adhering to, consolidation hole drilling work efficiency is increased Runode, the compaction holes sequentially drilling, by be busy the casing after drilling, be drilled compaction holes in adjacent locations, by a casing Since the protected consolidation hole is not affected, the consolidation hole excavator and the dust filling work to the consolidation hole can be carried out independently, and the casing has a smooth outer peripheral surface. It can be easily pulled out later.

Further, according to the present invention (Claim 2) , in the refuse disposal method in the waste disposal site, when filling the excavation hole with garbage, a weight having an appropriate length and weight is provided corresponding to the inner diameter of the excavation hole. In this case, the dust can be compressed and filled with a simple operation, and the volume reduction of the dust can be further increased.

  The present invention is a dust reduction method in which a casing is stowed after forming a consolidation hole, and the casing is pulled out at the time of charging or filling the garbage, and the consolidation hole is continuously excavated in a narrow area. Since it is possible to perform dust filling work independently of drilling work, effective use of work equipment (auger equipment, casing upright drawing equipment) has been realized, and waste volume reduction work has been performed efficiently. It is.

Further with using the auger a front portion provided with a spiral blade in Togarashi acute, intended to implement the excavation while air injected from the injection holes formed in the appropriate positions of the pressure-tight iron part, without crushing the garbage In addition, since dust is prevented from adhering to the consolidation iron portion, efficient consolidation drilling can be realized.

  Next, an embodiment of the method of the present invention will be described. The equipment used in the embodiment construction method is an excavator 2 that uses the auger 1, a casing 3, a crane machine 4 that is used to stand and pull out the casing 3, a shovel car (backhoe) 5, and a weight 6.

  The auger 1 has a maximum outer diameter (inner diameter of the consolidation hole A) of 1 m and a total length of about 10 m. The auger 1 is provided with a plurality of consolidation iron parts 12 on the outer periphery of the core part 11 serving as a cylindrical main body, and a spiral blade at the tip part 13. 14 and the mounting shaft 15 is provided at the base.

  The consolidation iron part 12 is composed of a iron plate surface 121 that gradually increases in diameter in the direction opposite to the rotation direction from the core part 11 and reaches a maximum outer diameter, and a back surface 122 that returns from the maximum outer shape part to the core part. A spiral shape twisted in parallel to the axial direction or on the opposite side to the rotational direction may be used, and provided in three directions radially from the core portion 11. In particular, the iron plate surface 121 is provided with injection holes 123 at appropriate intervals in the vertical direction. The injection hole 123 is connected to a high-pressure air supply unit including a vent pipe 16 that passes through the core 11 and a compressor (not shown) provided outside the apparatus.

  Moreover, the front-end | tip part 13 is formed in the taper shape from which the front-end | tip angle becomes an acute angle from the core part 11, and is provided with the spiral blade | wing which becomes large gradually to a drilling diameter corresponding to a taper shape. Further, the mounting shaft portion 15 has a shape that is mounted on a rotation driving unit 21 of the excavator 2 described later.

  The excavator 2 is a conventionally known excavator 2, and the traveling machine body 22 includes a tower portion 23, and the rotary drive portion 21 is incorporated in the tower portion 23 so as to be movable up and down.

  The casing 3 is a steel pipe or a vinyl chloride pipe, whose inner and outer peripheral surfaces are smooth surfaces, and whose outer diameter is slightly smaller than the inner diameter of the consolidation hole A. The weight 6 is a cylindrical shape having an outer diameter smaller than the inner diameter of the casing 3 and has a vertical length of about 2 to 3 m and a weight of about 500 kg.

  Moreover, the crane machine 4 and the shovel car (backhoe) 5 are civil engineering machines that are commonly used. The backhoe may also serve as the crane machine 4.

  Next, implementation of the construction method of the present invention using the equipment will be described according to work procedures. First, the excavation of the consolidation hole A is performed. The auger 1 is attached to the excavator 2, and the auger 1 is lowered from the surface of the garbage layer B of the disposal site while rotating the auger 1 (FIG. 1A).

  Then, since the tip 13 of the auger 1 is tapered and has the spiral blades 14, the auger 1 enters and descends so as to push dust into the dust layer B by its rotation. At the same time, the dust that reaches between the iron plate portions 121 of the auger 1 and the back surface 122 in front of it (rotation direction front) is pressed against the hole wall by the iron plate portions 121 as the auger 1 rotates. When the auger 1 is pulled up when the predetermined depth is reached, a non-discharge compaction hole A is formed in the dust layer B (FIG. 1B).

  When excavating the consolidation hole A, high pressure air is ejected from the ejection holes 123, so that compact dust is prevented from adhering to the iron plate surface 121.

  When the consolidation hole A is formed, the casing 3 is lifted by the crane machine 4 and stood in the consolidation hole A. The excavation of the consolidation hole A and the standing of the casing B are continuously performed, and the excavation and standing work is performed as much as necessary independently of the next dust filling (FIG. 1C). In particular, even when a new consolidation hole A is continuously excavated in an adjacent location, the consolidation hole A previously excavated is protected by the casing, so that the hole wall does not collapse.

  In the dust filling, after the casing 3 is stood in the compaction hole A, the dust C is carried out from the location where the dust is to be reduced by the shovel car 5 and put into the compaction hole A protected by the casing 3. After an appropriate amount is charged, the weight 6 is freely dropped into the consolidation hole A and a filling pressure is applied to the charged dust C. The dust C is sequentially charged and filled, and the compact C is filled with the dust C (FIG. D).

  Thereafter, the casing 3 is pulled out, and the dust volume reduction operation at that location is completed (FIG. 1E). The casing may be pulled out before the compaction hole A is filled with dust.

  By excavating several consolidation holes in this way and filling the consolidation holes with dust, it is possible to reduce the volume of waste at the waste disposal site and increase the utilization of the waste disposal site. It was made.
