Description

Protection method of an urgent stamping out livestock landfill

The present invention relates to a method of protection of emergency killing livestock burial, and especially by the leachate which is inevitably generated in the killing and burial land buried in emergency killing due to the fear of rapid spread of epidemic or avian influenza epidemic. It is to actively protect the landfilling buried land to prevent the spread of environmental damage, and injects a low-flow injection material to form an impermeable investment site shielding structure, and forms a leachate collection pipe protection structure in the middle of the impermeable investment site shielding structure. And install a leachate collecting duct in the protection structure of the leachate collecting duct, and actively collect environmental pollutants such as dead sludge and leachate through the leachate collecting duct to prevent environmental damage. It is about protection method.

In general, foot-and-mouth disease is a viral acute livestock epidemic that occurs in cows, pigs, sheep, deer, goats, etc., with two hoofs, and blisters on the mucous membranes of the mouth and the skin between the toenails. It is an epidemic that rises rapidly and shows appetite deterioration. It is designated as the first type of domestic animal transmission along with highly pathogenic poultry influenza.

Rapid transmission of infectious diseases when infectious diseases such as foot-and-mouth disease, high-pathogenic poultry influenza, right-sided disease, right-sided lung area, beeper, poultry cholera, poultry paste, etc. In order to prevent the killing and killing by the generation area is mainly used, the method of killing livestock disposal methods such as trench burial (trench burial), landfill, zoning mass burial (mass burial), etc. It is used.

Trench burial is a method of digging trenches with relatively small burial and embedding carcasses side by side in it, which is relatively quick, convenient and economical, and has less exposure to surroundings. Difficulties in site selection, potential environmental hazards, and post-treatment are not possible.

In addition, the landfill (landfill) is a medium-sized investment in the method of stacking and burying a certain amount of livestock carcasses, there is an advantage that can be quickly, mass processing, but the prediction of the time required for stabilization of the buried area is unclear, Due to this, it is difficult to identify the mechanism path and there is a risk of secondary foot-and-mouth disease caused by a transport accident.

And the zone designated mass burial (mass burial) is a large-scale burial method by designating a range of a certain area as a carcass treatment plant of the livestock, and buried treatment, there is an advantage that can be processed in a large capacity, and secured stability by planning treatment In addition, the site selection requires consensus with local residents, requires large-scale continuous monitoring of the wide area, and measures to bury the buried areas need to be established separately after stabilization.

Domestic livestock burial rules and guidelines currently include burial standards under livestock infectious disease prevention regulations, poultry influenza, foot-and-mouth disease, infectious spongiform encephalopathy, emergency behavior guidelines, and follow-up management of burial sites using tracers using groundwater methods.

1 is an exemplary view showing a killing land buried land according to the killing disposal buried manual according to these regulations and guidelines, the killing livestock investment method according to the killing land buried manual is excavated to a depth of 4 ~ 5m from the ground Forming (10), the step of laying quicklime and sawdust (11) in the killing land buried paper 10, the step of installing a double vinyl 12 on the bottom and wall surface of the killing land buried paper (10) , A step of forming a slaughtered livestock burying part 13 for cutting and burying a livestock boat disposed on the double vinyl 12, and covering 14 to a thickness of 2 m or more from the killing livestock burying part 13. Step, forming a leachate induction drainage channel to the lower than the floor of the killing land buried 10 or installing a leachate discharge pipe 16, the step of installing a leachate storage tank 17 at the end of the leachate discharge pipe (16) , Gas to the killing land buried (10) The step of installing the outlet 16 is designated to be performed sequentially.

As described above, it has been constructed in accordance with the manual of landfilling landfill in accordance with the regulations and guidelines for landfilling of landfilled cattle, or has been established by some insufficient procedures in case of emergency.

First, the killing land buried land (10) has been selected by the bird influenza emergency behavior guidelines (07.10) or foot-and-mouth disease guidelines (04.10) where the killing land buried land (10) is selected in the vicinity of the place where the livestock to be buried occurred. It is buried, and this location is usually easy to excavate and formed in agricultural areas where agricultural waterways are connected to soil layers with good permeability, so that carcass sludge, leachate, and mass-induced infectious diseases that occur along with decay and decomposition of livestock carcasses Hazardous pathogens, etc. are leaked into the soil and pose a risk of spreading.

Secondly, cadaver sludge and leachate from the landfill landfill 10 were penetrated into the pores of adjacent soils, and the soil was denatured, resulting in degradation of the engineering characteristics of the ground, which could act as a factor of ground instability.

Third, if the groundwater level rises during the rainy season or the peak season, there is a possibility that the group hospitals and the environmentally harmful factors are leaked to the surface and spread in the region.

Fourth, the high concentration of organic substances permeated into the ground due to the decomposition and decay of livestock carcasses in the killing land buried 10 causes eutrophication in the soil, and acts as a nutrient supply for high pathogenic bacteria such as anthrax that is present in the soil. You can get diffusion,

Fifth, it is a treatment method that waits until the environmental pollutants caused by the decomposition and decay of livestock carcasses and decay in the killing land buried 10 is released into the soil or disappears naturally. There is this.

The presently applied method for preventing secondary environmental damage of the killing land buried (10) is to form an impermeable water-repellent wall around the land killing land (10) or to install a structure such as a retaining wall, stonework for the weak ground It is a passive way to reinforce.

This method prevents the spread of environmental pollutants in the surface waters by the order walls in a planar manner, and even though it has the effect of stabilizing the adjacent grounds, the result is that the pollutants are induced into the deep underground water passages. It is not a reasonable method for long-term protection. Therefore, a more rational and stable method is to establish active protection and treatment measures for pollution sources, and an alternative is needed.

Accordingly, the present invention has been made to solve the problems described above, and live in the process of decomposition and decay of livestock carcasses buried in the burying land buried in the emergency management process to buy factors that can cause environmental disasters It is to derive a plan that can minimize the impact on the human environment and the soil environment by actively protecting from disposal sites (sources).

Killed livestock carcasses to prevent the outflow of pollutants and environmental impact factors by simultaneously shielding the landfilled landfill, which is the source of environmental damage, from the flow of adjacent soil and surface water, and to restore the landfilled land as soon as possible. In order to ensure that the decomposition and decay process of the chemicals is limited within a limited range, and to effectively limit the space for supplying oxygen, or to promote decay, sterilization, or soil purification materials,

Low flowable injection materials such as small cement mortar or lightweight mortar, which can be effectively injected into the interface between the killing landfill and the ground plate, can form an impermeable investment site shielding structure. And forming a shielded structure, forming a leachate collecting oil pipe protection structure on the impermeable investment site shielding structure, and by installing a leachate collecting oil pipe for recovering the leachate perforated in the leachate collecting oil pipe protection structure Collecting sludge sludge, leachate, and other environmental pollutants to prevent environmental damage, and to ensure that the shielded landfill site can be restored to its original purpose in the shortest possible time, Emergency killings to ensure efficient supply The purpose is to provide protection for livestock burial.

Emergency killing cattle buried land protection method according to the present invention for achieving the above object in the killing land was buried, puncture equipment to puncture the bottom of the bottom and wall portion of the killing land buried to a predetermined depth to form a hole Thereafter, the organic material infiltrated through the perforated hole does not mix with the raw alumina, and condensed injection diffusion of a low-flow injection material capable of forming pure solidified body to form a high-purity, high-strength impermeable burial shield structure, such an impermeable Consolidation injection of low flow injection material in the process of forming the buried land shield structure consolidates the organic soft soft soil around the killing land buried in all directions and increases the soil density to stabilize the ground by improving the engineering characteristics.

Environmental impact by installing leachate collection pipes in the bottom of the slaughtered landfill site as a measure for collecting and transporting dead sludge and leachate generated from raw soil and shielded landfill landfills for proper disinfection and purification. Find ways to actively control factors,

Multi-use burial management material that can supply oxygen, inject corruption promoters, inject disinfectant disinfectants, or soil purifying materials in stages as necessary to promote the decomposition and decay of livestock carcasses buried in the killing land. By installing injection pipes, we have established measures to normalize the land of the landscaping site in a relatively short period of time to actively protect the landscaping site, and the efficient and proactive follow-up of the factors that will cause environmental impacts that were not prepared in the emergency protection process. It is characterized by presenting measures.

As described above, the urgent killing livestock burial site protection method according to the present invention has the following effects.

First, the follow-up measures of existing landfill sites were passive reinforcement measures to prevent the formation of order walls around the landscaping sites or to damage or destroy the surrounding grounds of the landfill sites. Leachate or harmful pathogens contained in the leachate may cause adverse effects in the surface water zone rather than inducing it into the deep underground waterway.

The present invention actively protects leachate and environmental damage material from the source as the concept of actively protecting the buried land buried, block the leachate entry into the deep underground waterway, block soil erosion and decay by limiting the soil pollution range In addition, it can block the release of environmentally harmful substances beyond the scope of the soil self-purification function.

Second, the present invention has an advantage of an economical method because the construction cost is significantly reduced compared to the existing method of forming the order wall around the construction range is minimized.

Third, the impermeable investment site shielding structure of the present invention can limit the scope of management of environmental pollution sources to a certain range, which can normalize the soil environment and the human environment in a relatively short time by legally managing environmental pollution sources and in a systematic manner. There is an advantage.

Fourth, the present invention has little or no effect of soil characteristics and soil water flow conditions and seasonal fluctuations of the soil layer formed with the landfilled buried land is minimized, and has the effect of reinforcing the ground according to the terrain conditions.

Fifth, the low-flow injection material of the present invention expands radially upon pressure injection in the ground, and solidifies itself regardless of the physical and chemical properties of the raw soil, and in the process, consolidates the surrounding soil of the landfill site to minimize voids. In order to stabilize the ground, high purity and high strength structure and adjacent ground reinforcement are simultaneously performed.

Sixth, the impervious burying site shielding structure by the urgent killing livestock burying land protection method according to the present invention maintains a chemically stable state in the ground, even if it remains permanently in the soil, there is no effect on the soil environment, durability As a result, the effectiveness of the initial formation is maintained until the killing livestock burial site management period and the soil normalization period.

Figure 2 is an exemplary view showing the emergency killing livestock buried protected after taking the follow-up measures according to the method of emergency killing livestock buried in accordance with the present invention.

Hereinafter, with reference to the accompanying drawings, the present invention will be described in detail.

Figure 2 is an exemplary view showing the emergency killing livestock buried land protected after taking the follow-up measures according to the emergency killing livestock buried land protection method according to the present invention.

As shown in this figure, emergency killing cattle buried land protection method according to the present invention is excavated to a depth of 4 ~ 5m from the ground to form a killing land buried (10); Disposing quicklime and sawdust (11) on the landfill burial (10); Disposing a double vinyl (12) on the bottom and the wall of the killing land buried (10); Dividing the belly of the animals slaughtered on the double vinyl (12) and forming a slaughtered cattle buried part (13); A step (V) of covering the soil (14) to a thickness of 2 m or more from the killing livestock burial portion (13); (VI) forming a leachate induction drainage channel or installing a leachate discharge pipe (16) to a lower portion than the floor of the killing disposal landfill (10); (Ⅶ) installing a leachate storage tank (17) at the end of the leachate discharge pipe (16); (Ⅷ) installing a gas discharge pipe (18) in the killing land investment land (10); Perforating the killing disposal landfill (10) to inject and cure a low flow injection material (M) to form an impermeable investment site shielding structure (S) around the disposal landfill site (10); Perforating the center of the impermeable investment site shielding structure (S) to inject and cure a low flow rate injection material (M) to form a leachate collecting oil pipe protection structure (T); Inserting the leachate collecting oil pipe (HP) into the leachate collecting oil pipe protective structure (T), the leachate discharge pipe 16 is installed in the leachate collecting oil pipe (HP), the leachate at the end of the leachate discharge pipe (16) Installing a storage tank (17); And installing a multi-use investment site management material injection pipe (AP) in the killing land investment site (XII).

Here, the low fluidity injection material (M) is composed of a cement cement and small soil mortar consisting of local soil and stone, or is composed of lightweight foam concrete, urethane.

In addition, the low flow rate injection material (M) is composed of a slump (slump) of 5 cm or less.

In addition, the step of perforating the cover 14 to inject and harden the low-flow injection material (M) to form a water-impermeable buried paper shield structure (S) at the bottom of the cover 14 is added.

In other words, the method of protection of emergency killing cattle buried land according to the present invention is a secondary environmental damage caused by leachate generated from the decomposition and decay of livestock carcasses in the killing land buried in the killing place (10) that was killed in the emergency protection process It is characterized in that the impermeable investment paper shielding structure (S) is formed of the bottom and the wall surface of the killing landfill land 10 for preventing the diffusion of the low-flowing injection material (M).

Here, the step of forming the impermeable investment site shielding structure (S) is to form a water impermeable investment site shielding structure (S) by perforating the killing disposal investment site 10 to inject and cure a low-flow injection material (M), Punching holes by drilling the bottom and wall portions of the killing landfill lands 10 with a predetermined depth on the upper and side surfaces of the landslide 14 of the landfill landfills 13 of the disposal landfills 10 to a predetermined depth. After forming, the injection pipe is inserted into the drilling hole in the depth of 0.5 ~ 1.0m or spaced from the bottom and wall surface of the killing land buried paper 10 to inject a low-flowing injection material (M) at that location In the step of forming an impermeable investment site shielding structure (S) to separate the (10) from the earth alumina, the low-flow injection material (M) can be used for materials having a slump of 5 cm or less, such as soil cement mortar, lightweight foam concrete, urethane Ground injection characteristics, base ground Associated with the re-chemical properties and anti-caking properties juipjae, the order of performance and structural quality stability, a method of injecting a low pressure fluid juipjae (M) with the most excellent material properties and workability in the durability.

Such impermeable investment site shielding structure (S) is a structure for preventing the leakage of livestock carcass leachate in the killing land buried land 10 killed by an emergency protection process.

By injecting such a low-flowable injection material (M) into the landfill landfill 10, if necessary, the construction of the supporting structure by improving the ground strength characteristics by increasing the ground density or forming the high-quality impermeable investment site shielding structure (S) It is possible to construct economically to meet the purpose of preventing leachate spillage.

In addition, the injection and injection of a mobile injector to prevent the loss of injection pressure during the production and transport of the low-flow injection material (M), quality degradation, such as material separation, and to effectively and homogeneously perform consolidation injection in the buried land (10) Injecting downward pressure using a pump to maximize the ground compaction injection effect, and according to the specification of the impermeable investment site shielding structure (S) and the conditions of the disposal site (10), low flow to the disposal site (10) Homogenization of construction quality is also aimed at by using a normal injector so that injection of an injection material can be made uniform.

That is, the low-flow injection material (M) is injected into the perforation site and diffused into a homogeneous mass to push the soft soil of the killing land investment land in all directions to increase the density around the land disposal land investment land (10). At the same time, the low-flowing injection material M injected around the killing land investment land 10 is cured to form a water-permeable investment land shield structure S having a predetermined shape, and the livestock carcasses are removed from the land disposal land site 10 by a livestock carcass. Prevent leachate from leaking out.

In addition, the step of forming the leachate collection pipe protective structure (T) is a number depending on the form and specifications of one central portion of the killing land investment land (10) or killing land investment land (10) for effective induction and lifting of leachate In the same way as the formation of the impermeable investment site shielding structure (S) in the lower portion of the impermeable investment site shielding structure (S), the center portion of the impermeable investment site shielding structure (S) is drilled, and a low flow rate injection material is formed in the perforated portion. (M) is injected and cured to form a leachate collecting oil pipe protection structure (T) separately on the center outer side of the impermeable structure (S).

And the leachate collecting oil pipe (HP) installation step is easy to infiltrate the leachate discharge pipe 16 into the leachate collecting oil pipe protective structure (T), and in case of emergency, the leachate collecting oil pipe (preferred) HP), and the pore portion into which the leachate flows into the leachate collecting oil pipe (HP) is introduced by perforating the pipe according to the depth of the slaughtered livestock burying part (13).

In this way, if the leachate flows into the leachate collecting oil pipe (HP) installed in the leachate collecting oil pipe protective structure (T) and the leachate rises above a certain level, the automatic pump pump recognizes this and the inside of the leachate collecting oil pipe (HP) The leachate discharged to the outside through the leachate discharge pipe (16) installed in the leachate discharged in this way, after the primary treatment and storage of sterilization, etc. in the leachate storage tank (17) connected to the tip of the leachate discharge pipe (16), 2 Take it out to the designated place by car.

In addition, the multi-use investment site management material injection pipe (AP) installation step, the livestock carcasses buried in the killing cattle buried land is decomposed by natural decay after a certain time, in order to speed up such decomposition, killing land buried (10 In the step of installing a multi-use investment site management material injection pipe (AP), the decomposition and decay of the livestock carcasses in the killing livestock burial unit 13 is aerobic decomposition, acidic anaerobic decomposition, anaerobic decomposition depending on the amount of oxygen If the oxygen concentration is low and enters the anaerobic digestion step, the cadaveric decomposition and decay may proceed for several decades. Therefore, it is necessary to artificially supply oxygen for the early stabilization of the landfill site 10. In addition, if the need to add a disinfectant disinfectant, or a corruption promoting agent or a soil purification material such as water-soluble silicate as needed, Versatile paper management investment material inlet tubes (AP) can thus not intrusive to the 10-year-old burial disposal.

On the other hand, take additional measures for missing or insufficient measures in the process of investing in emergency killings, and if necessary, carry out reinforcement to prevent the inflow of surface water, and if necessary, cover the site (14). In order to prevent the leachate from coming up or the cover 14 to be turned off, the cover 14 is drilled to inject a low fluid injection material M into the upper portion of the livestock buried portion 13 or the cover 14 to cover the cover. (14) Stabilization of the ground and an impermeable investment site shielding structure (S) may be formed.

Emergency killing cattle buried land protection method according to the present invention consisting of the steps as described above can actively cope with the leachate spread control, can block the leachate and environmental damage from the killing land buried land (10), the source The formation of an impervious investment site shielding structure (S) can effectively prevent leachate from spreading through surface water zones or entering into deep groundwater passages and spreading wide-area, and prevents soil erosion and decay due to the limitation of soil pollution, and the soil itself. It has the effect of blocking the outflow of environmentally harmful substances beyond the purifying range.
