Description

  The present invention relates to a garbage disposal method that realizes volume reduction of garbage in a waste disposal site and realizes effective disposal of industrial waste.

  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, and Japanese Patent Application Laid-Open No. 10-102475 ( In Patent Document 2), a hole is formed in the deposited waste with a compression rod provided with a cutting blade in a state where the tip portion crosses in a cross shape and the center portion protrudes most and recedes from the center portion. Means for charging waste is disclosed.

  Furthermore, in JP-A-10-272432 (Patent Document 3), JP-A-2001-286843 (Patent Document 4), and JP-A-2006-15262 (Patent Document 5), a consolidation hole is provided in a waste disposal site. Means for excavating and filling the excavation hole with dust is disclosed.

Japanese Patent Laid-Open No. 7-16555. JP-A-10-102475. Japanese Patent Laid-Open No. 10-272432. JP 2001-286843 A. JP 2006-15262 A.

  As described in Patent Documents 3 and 4, a void (consolidated excavation hole) is formed by dust compression, and the volume of the dust is reduced by introducing surface layer garbage into the void (excavation hole). The conventional means is basically intended to reduce the volume of garbage at the garbage disposal site. For example, as for the treatment of waste that requires a certain treatment such as asbestos waste. Is not considered at all.

  The dust volume reducing means of Patent Document 3 uses a drilling earth and sand compacted auger provided with a trowel part provided so as to rise spirally in the direction of excavation rotation, and excavates and drills without discharge. In the state in which it is inserted into the hole, it is rotated backwards and pulled out, while dust is thrown in from the hole mouth, dropped to the bottom of the hole, consolidated into the hole wall with a trowel, and the rest is sequentially deposited on the bottom of the hole In the case of crushed garbage, it cannot be put into the excavation hole.

  Further, the dust volume reducing means described in Patent Document 4 uses a drilling device comprising a casing provided with a compacting iron on the peripheral surface, and a drilling rod having a drilling head that passes through the casing and protrudes from the tip. There has been disclosed a volume reduction means for dust, in which non-discharge excavation is performed with a compacting iron, surface dust is put into the casing with the casing remaining, and the casing is later pulled out. There is a problem that becomes resistance to pulling out.

  In the dust volume reducing means described in Patent Document 5, a non-discharge drilling hole (consolidation hole) is formed at a dust accumulation location using a predetermined auger, and then a casing having a smooth outer peripheral surface is set up in the drilling hole from which the auger is pulled out. However, it is described that the casing is withdrawn while charging or filling the casing with or after filling the casing, but the drilling hole formation and the casing standing are separate operations, which cannot be said to be an efficient operation. No consideration is given to the disposal of hazardous industrial waste.

  Therefore, the present invention proposes a garbage disposal method in a waste disposal site capable of disposal of particularly harmful industrial waste such as asbestos.

In the waste disposal method according to the present invention, a waste input space protected by a casing with a smooth outer peripheral surface is formed by non-discharge excavation at a dust accumulation location, and the elongated bag-like covering is formed in the space After inserting the waste material into the covering body, pouring a sealing body such as mortar into the top of the input waste, closing the mouth of the covering body and pulling out the casing, or without inserting the covering body. , Put the waste packaged in a predetermined covering into the casing, pull out the casing,
It is characterized in that surface waste is thrown into the remaining space and processing waste is buried.

  Thus, since the object to be discarded is embedded in the collected garbage in a state of being wrapped in a covering, it is possible to easily handle harmful waste.

  In particular, the present invention (Claims 2 and 3) exposes a drill body including a shaft portion that can be linked and a drilling drill portion that matches the inner periphery of the casing at the tip of the shaft, and the drilling drill portion is exposed from the tip of the casing. The shaft is connected to the casing at the top of the casing so that it can be rotated and installed in the casing. The casing is rotated and driven into the dust accumulation site. After driving to the desired depth, the drilling drill is removed from the upper end of the casing and discarded. It is characterized by forming an article input space.

  Thus, by mounting the excavation drill body on the casing and rotating the casing, the casing is stood up while removing accumulated dust with the excavation drill, and excavation and casing upset can be performed simultaneously.

  Since the configuration of the present invention is as described above, it is possible to reduce the volume of trash at a waste disposal site that is a garbage collection site, and toxic industrial waste can be easily disposed of in an industrial waste disposal site. It is used effectively.

  Next, an embodiment of the present invention will be described. The implementation apparatus of the present invention includes a casing 1, a drilling drill body 2, a drill body mounting member 3, and a casing drive mechanism 4.

  The casing 1 is a φ1500 mm hollow double tube (a known one having a grid-like rib provided between the inner cylinder part and the outer cylinder part) with a smooth outer peripheral surface. The joint portion 11 is formed, and the connecting pin 12 can be connected to a desired length.

  The excavation drill body 2 is formed by an excavation drill portion 21 and a shaft portion 22, and the excavation drill portion 21 has a size that matches the inner periphery of the casing at the tip of the shaft portion 22, and scrapes the object to be excavated (accumulated garbage A). It is a structure that excavates. The shaft portion 22 can be connected, for example, provided with an insertion connecting shaft portion 23 and an insertion hole portion at the upper and lower ends, and a connecting pin penetrating the previous insertion connecting shaft portion 23 and the insertion hole portion. The hole 24 is provided, and is connected to the plug and fixed with a connecting pin, so that the length corresponds to the casing length.

  The drill body mounting member 3 has a ring shape and includes a connection pin provided at the top end of the shaft portion 22, having the same structure (the fitting portion 31 and the connection pin 32) as the casing connection structure at the top of the casing 1. A connecting shaft 33 that can pass through the hole 24 is constructed.

  The casing drive mechanism 4 is an existing device that rotationally drives the casing 1 in the holding state.

  Implementation of the method of the present invention will be described using the above-described implementation apparatus. The drill body mounting member 3 is connected and fixed to the top of the casing 1, the drilling drill portion 21 is exposed from the tip of the casing 1, and the connecting shaft body 33 is inserted into the connecting pin hole 24 at the upper end of the shaft portion 22. The body 33 is fixed to the main body of the drill body mounting member 3 so that the casing 1 and the excavation drill body 2 can be rotated, and the casing drive mechanism 4 is installed at the excavation position where the garbage A is collected in the waste disposal site. Then, the casing 1 and the excavation drill body 2 that are integrated with each other are suspended by a crane or the like and erected at a predetermined position of the casing drive mechanism 4 (FIG. 3).

  Next, the casing 1 and the excavation drill body 2 are rotated, the accumulated dust A is scraped by the action of the excavation drill portion 21, the casing 1 is stood in the accumulated garbage A, and the casing 1 and the excavation drill body 2 are appropriately connected. When excavation is completed to a desired depth (FIG. 5), the excavation drill body 2 is taken out from the upper end of the casing 1 (FIG. 6).

  When the excavation drill body 2 is taken out, the waste input space B is formed in the casing 1, and the elongated bag-like covering body C is inserted into the space B. The covering body C is made of vinyl or rubber and has sufficient strength and water tightness.

  Hazardous industrial waste D such as asbestos that needs to be buried is thrown into the cover C (FIG. 7), and a sealing body E such as mortar, concrete, bentonite, etc. is poured into the top of the input waste, and the cover The mouth of C is closed and the casing 1 is pulled out (FIG. 8). The casing 1 is pulled out before the mortar is solidified.

  After the casing 1 is pulled out, a remaining space F remains in the upper part (FIG. 9), and the waste A to be treated is buried in the remaining space F to bury industrial waste D to be treated harmfully. Is finished (FIG. 10).

  Therefore, in the existing waste disposal site, harmful industrial waste is buried in the collected garbage A in a sealed state, so that harmful industrial waste can be disposed of reliably and easily, It was also possible to reduce the volume (volume) of garbage at the garbage collection site by forming no discharge drill holes.

  Further, the excavation and installation of the casing is not limited to the above-described embodiment. Similarly to the conventional excavation means, after the non-discharge excavation with an auger or the like is performed to form the excavation hole, the casing is inserted into the excavation hole. You may employ | adopt the means to stand up.

  Further, when the industrial waste D is thrown into the waste input space B, the industrial waste D has sufficient strength and functions (watertightness, chemical resistance, etc.) corresponding to the contents of the industrial waste D in advance. It may be packaged with C, and the industrial waste D packaged with the cover C may be thrown into the waste charging space B protected by the casing. In this case, the sealing body E may not be used, or the industrial waste D may be pressed down by inserting a plug made of solid material instead of the sealing body E.
