Description

Explosion-proof dustproof method by ground cutting

The present invention relates to an explosion-proof anti-vibration method by ground cutting that significantly reduces construction costs by actively blocking and offsetting seismic force transmitted from the epicenter to protect a specific area or structure and thus simplifying construction. .

In general, as a method for protecting a structure from an earthquake, it is a passive method in which a seismic facility is absorbed by the structure itself to absorb the seismic force transmitted in the event of an earthquake. There is a way to protect the damage from earthquakes by simply blocking the seismic waves transmitted to a specific area and structure (B) by installing a separate dust-proof structure, which is mostly passive or to protect the seismic waves transmitted from the epicenter. By taking a defensive defensive form, they are not completely absorbed or exhausted.

As shown in FIG. 1, a dustproof opening 1 for vertically forming a heterogeneous layer composed of an air layer by excavating the ground in an open trench type is illustrated as a related dustproof structure. Since the conventional dustproof opening 1 blocks the horizontal transmission of the seismic vibration wave in the air layer, the damage of the earthquake can be reduced.

However, the conventional dustproof device 1 is not only increased in cost to excavate at the required depth and length, but also has a problem that maintenance is difficult because the air layer is open and there is a risk of empty wall collapse. there was.

Recently developed to solve this maintenance problem, as shown in Figure 2, after excavating the ground in an open trench type by the diaphragm wall, the band shape using the membrane and geotextile There is an anti-vibration structure in which an air tube mat (2), which is continuously connected to an air cyst of the tube shape, is placed, and a kind of air tube mat anti-vibration wall (4) filling the concrete (3) is filled in the ground.

This type of dustproof structure has a good dustproofing efficiency similar to that of an open trench type by embedding an air tube mat in the ground, and it does not require maintenance after construction. Excavation costs are still high, and high technology is required to mount the air cysts of the air tube mat, and the dust pressure is reduced due to the problem that the air pressure of the air cysts decreases over time. There is a problem.

Therefore, the present applicant is to avoid the seismic concept having the form of earthquake-proof by installing the seismic installation on the general structure itself, to offset the earthquake wave (E) approaching the structure from the outside of the structure in advance, or to create several heterogeneous layers. The invention has been invented to take a more aggressive and aggressive form of dust protection to protect certain areas and structures (B) more fully.

Descriptions of the terms "airbag", "ground wall material" and "ground mine" used below are as follows.

"Airbag" is a primer and explosives loaded in the armed holes formed with a fine trench, the high-pressure gas generated during the explosion has a function to block the seismic waves by building a gas wall inside the gap of the fine trench,

"Underground wall material" is a structural part composed of a heterogeneous layer which absorbs seismic motion or absorbs the generated gas by filling the space part of the entire inner surface of the micro trench with grout material, while moving upward with the gas generated as a micro-float during underground airbag explosion. Has the function to block seismic waves,

"Underground mines" are explosives that are loaded in the charge holes built along a certain line of ground at the forefront of the epicenter. They have the effect of offsetting and blocking seismic waves in the destruction layer created by blasting the cancer on the back. It is preferable to generate an artificial elastic wave by the shock wave generated at the time and to interfere with the seismic wave and to interpret it as having the function of canceling the vibration of the seismic wave.

The purpose of the present invention is to install dustproof structures on the edges of specific areas and structures to protect them safely from the sea.In addition to the traditional concept of seismic protection, they introduce an offensive concept of aggressiveness against seismic forces. Explosion-proof dustproof method by ground cutting that blocks seismic force by several heterogeneous layers and generates reverse elastic wave colliding with seismic wave of seismic wave, interfering, canceling and dispersing seismic wave to protect specific area and structure from the sea To provide.

Another object of the present invention is to install a structural part that can actively block and offset seismic forces underground without digging the ground, so that the construction is easy, the dustproof effect is excellent, and the explosive dustproofing by the ground cutting can greatly reduce the construction cost. To provide a process.

Hereinafter, the technical configuration of the present invention will be described.

Explosion-proof dustproof method by the ground cutting according to the present invention, as shown in Figures 3a to 4b, alternating perforated alternating armed holes (11) and charged holes (12) in the vertical direction along a predetermined line in the ground alternately Thereafter, a small amount of ground cutting explosives 13 are installed in a few tens of layers in the charge hole 12 to form a fine trench 10 by tensile destruction by detonating, and then the inside of the fine trench 10. Air bags for airbags (21) installed in the dozens of layers to build the underground airbags 20, and drilled the underground mines (31) along a constant distance in front of the underground airbags (20) The underground mine (32) is used in the construction of the heterogeneous layer and the explosive detonation in the underground mine (31) in a few layers to build the underground mine (30), the explosives for air bags 21 and underground mines ( 32) Detects seismic waves delivered to each and automatically detonates It is a basic technical idea of the present invention to install the detonation means 40 to turn on.

Here, the airbag explosives 21 of the airbag stand 20 and the ground mines 32 of the underground minefield 30 are detonated with a slight time difference for each hole, but the explosive charges 21 for the airbags of the airbags in the rear After this first explosion, it is preferable that the ground mine 32 of the ground minefield in front of the explosion explodes later.

This is because the relatively explosive airbag explosive charge 21, which is installed in the airbag stand 20 at the rear, is exploded to form a blocking film first, and then the ground mine 32 having the strong explosive energy in the front is exploded, thereby protecting it. It can effectively protect certain areas and structures (B).

Therefore, in the present invention, when the earthquake is generated from the source and the seismic wave (E) reaches the independent area or around the structure, the detonation means 40 detects the seismic wave (E). The detonation means 40 analyzes and judges the seismic wave E to instruct and detonate the air bag explosive charge 21 and the underground mine 32, respectively.

4B shows that the explosives 21 and ground mines 32 for the present invention form foreign matter layers to neutralize the seismic waves when they are exploded.

After the airbag stand 20 is first exploded to form a gas wall layer w which functions as a film to block the space, the underground mine shaft 30 at the front thereof explodes strongly and the rear airbag stand A breakdown layer (x) is formed toward the gas wall layer and at the same time, the gas is blown upwards to form a double layer that blocks the space of the breakdown layer, and a crack layer (y) is formed immediately before the gas barrier material layer. In the front side, four layers of heterogeneous layers are formed in which the elastic wave layers z in the opposite directions collide with the propagation direction of the seismic waves are formed.

Therefore, the seismic wave E is blocked, exhausted and canceled step by step in the order of four different foreign matter layers, that is, the elastic wave layer z, the crack layer y, the fracture layer x and the gas wall layer w from the foremost. .

The micro trench 10 is formed by cutting a ground of a specific area to be protected and the outer periphery of the structure B to a predetermined depth, and is for forming an underground gas wall layer which is a strong heterogeneous layer when an earthquake occurs. .

As shown in FIGS. 3A and 5A, the method for forming the micro trench 10 drills the armless holes 11 and the charge holes 12 to a predetermined depth and is installed in the charge holes 12. Install the explosives for cutting (13) in a layered manner, and install the chromosome (A) between them, and then, depending on the detonation, between the charge hole (12) and the armless medicine hole (11) by tensile breakdown It is cut by the micro vibration.

As described above, the micro trench 10 may not only form a heterogeneous layer by simply cutting the hole and the arm hole in the vertical direction and cutting it with tensile fracture force, but also compared with the conventional open trench type by the excavation. It can be formed deep into the ground so as not to be, and the construction cost is possible at less than 1/10 of the prior art.

The technique for forming the fine trench 10 is disclosed in Korean Patent Laid-Open Publication No. 97-68802 and Japanese Patent Application No. Hei 9-251769 published by the present applicant, "A method for cutting rock by tensile force." Since the description is the same, a detailed description thereof will be omitted.

After forming the fine trench 10 by cutting the ground by the above-described technique, air bag stand 20 is constructed by installing air bag explosives 21 in layers at predetermined intervals in the armed medicine hole inside the fine trench 10. Done. The airbag stand 20 serves to block the seismic wave (E) by forming a gas wall inside the fine trench 10 when the explosive charge for the airbag 21 is exploded.

Here, the explosive charge for airbag 21 is installed in the already opened armed medicine hole 11, as shown in Figs. 3a, 3b and 5b, but dozens of mines in which a very small amount of unit explosive (30-70g) is built-in. Installed in layers.

At this time, a primer 42 is inserted into the mine, and it is necessary to treat it tightly so that groundwater does not penetrate into the primer 42. In case of explosion, mines are blasted continuously with detonation parallax, and they are blown from top to bottom.

Air bag stand 20 is installed in this way, when the explosives for the air bag 21 is exploded, the high-pressure gas generated from the explosives forms a gas wall in the entire micro trench 10 to block the seismic wave (E), so the damage of the earthquake Can be reduced.

For reference, the airbag 20 is loaded so that there is no effect on the ground even when an unexpected explosion is made, so that scattering, drinking and ground displacement do not appear. If an earthquake occurs without warning or action, it should be loaded to the extent that it can be fully detonated by itself by the ground stenosis and friction, or by the detection signal by the overload earthquake vibration value.

In addition, each line of mine primer should be coated to prevent deterioration for a long period of time, and reinforce the tensile force so as not to be broken or stretched. Landmine primers and busbars are wired to load each two circuits for safety and certainty. It is desirable that these mines be replaced every 10 years to ensure that their safety and accuracy are maintained continuously.

Meanwhile, as shown in FIGS. 3B and 5B, the underground wall material 22 is formed inside the airbag stand 20. The underground wall material 22 is a structural part formed on the entire inner surface of the micro trench 10 by injecting it through the charging hole 12 that has already been drilled with the grout material.

The underground wall material 22 prevents the fine trench 10 from sinking in the outer wall, and also serves to prevent foreign substances such as groundwater, earth and sand, and the like from entering.

The underground wall material 22 is crushed by the heat and pressure of the explosion during the explosion of the explosives 21 for the airbag to be dusted to form a foreign matter layer in the trench to help block the seismic wave (E).

The underground wall material 22 itself must have a certain degree of anti-vibration effect and have a lot of voids or cushioning and elasticity. In addition, the ground wall material 22 may be more scattered in the fine trench when the air bag is exploded, or more affinity with the gas. As a material of such easily dispersible underground wall material 22, a soft urethane, a porous styropole or a porous rubber ball may be selected.

Meanwhile, as shown in FIGS. 3B and 5C, the underground minefield 30 is constructed along a predetermined line in front of the airbag stand 20, that is, at the forefront of the epicenter, to actively interfere with the seismic wave E to cancel. It is to play a role.

That is, the underground minefield 30 drills the underground mines 31 in a vertical direction at regular intervals along a certain line of the ground, and then includes an underground mine 32 having a relatively large unit width (500 to 2,000 g). It is installed spacingly on the floor.

Therefore, the underground minefield 30 detects the seismic wave (진) from the source and makes the underground mines 32 violently explode by the detonation command of the detonation means, thereby interfering and offsetting the seismic wave (E). do.

The principle of ground mines is to detonate a certain number (30-50%) of the nucleus, which is formed at the time of explosion, or to explode it. The reflection causes the heterogeneous layer to be primarily caused by the forced movement of the groundwater, and the seismic interference and the offsetting effect to the secondary.

The underground mine 32 has an interference and offset against seismic waves by forming an offensive form of a "V" shape by breaking energy, unlike the airbag stand 20 forming a gas wall by an "-" shaped air cushion. Or to have a disturbing effect.

In more detail, when the underground mine 32 is exploded, the first function is to offset seismic waves by actively inducing seismic waves facing the seismic waves, and secondly, airbags that are passively constructed at the rear. (20) It serves to help the formation of gas walls by supplying a large amount of additional gas to the inside, and thirdly, refractory, reflection, attenuation, and Offset role.

The above-mentioned ground mine 32 can use various types of explosives, but in the embodiment of the present invention, it has been found that an underground mine having a strong breaking energy loaded with a large amount of unit explosive dose (500-2,000 g) is used. Put it.

The underground mines installed in these underground mines (30) should be exaggerated (+ 20%) than the amount of general blasting, and will be loaded on the basis of the concept of demolition of rock blasting based on the pendulum principle.

On the other hand, it is also possible to expand the destruction energy by reinforcing a plurality of satellite underground mines around each unit underground mine 32.

The detonation means 40 is a structure that detects and automatically detonates seismic waves delivered to the ground airbag explosives 21 of the underground airbags and the ground mines 32 of the underground minefield.

As shown in Fig. 6, the detonator 40 shows a form in which two kinds of detonators are installed at the same time as the first detonator provided in the upper part and the second detonator provided in the lower part. Means 40 are seismograph 41 for detecting seismic waves transmitted from the source, primers 42 loaded in the air bag explosives 21 and the ground mine 32, respectively, the seismograph 41 and the detonator It is composed of a detonator circuit 43 for interconnecting the (42) to detonate the detonation command of the seismograph to the detonator 42.

Here, the seismograph 41 is installed in the office far away from the underground mine platform 30, and the main computer 41a that directly detects the seismic wave (P wave) and reads the vibration value of the seismic wave. It consists of an earthquake monitor 41b sent to the main computer 41a.

Therefore, the main computer 41a analyzes and judges the vibration value read by the seismic monitor 41b, and transmits the detonation command to the primer 42 through the detonation circuit 43, and detonates it. At this time, when the main computer 41a analyzes and judges the vibration value and issues the detonation command, the detonation command can be issued only above the designated vibration value in consideration of the earthquake history and the underground mine target structure.

The second detonator 40 is attached to the airbag explosives 21 and the underground mine 32, respectively, and is buried together, and is transmitted from the sound wave receiver 45 and the sound wave receiver 45 for detecting seismic waves. A sound wave detector 46 for analyzing and judging an incoming signal, a switch 47 operated by the sound wave detector 46 to conduct current, and delivering and energizing the energized current to the primer 42 for detonation. It shows an example consisting of a detonator circuit 48.

Therefore, when the wave receiver 45 receives the seismic wave (P wave) and sends it to the sound wave detector 46, the sound wave detector 46 reads, interprets, and judges the vibration value, and issues the detonation command through the detonation circuit 48. Detonation is delivered to the primer 42.

At this time, when the sound wave detector 46 analyzes and judges the vibration value as in the first detonation means 40 and issues the detonation command, the detonation command is made only at the designated vibration value or more in consideration of the earthquake history and the underground mine target structure. To let go.

Although only one of the two detonation means 40 can be selected and installed in the explosive, as in the embodiment of FIG. 6, both detonation is securely performed at the same time in order to prevent an accident due to a failure. It is desirable to be able to.

On the other hand, as shown in Figures 3b and 4, the back of the air bag 20 in the vertical direction by drilling the smoke hole 51 in a vertical direction to connect the bottom portion in communication with the air bag 20 After drilling through the passage 52, the high pressure gas filled in the smoke cylinder (53) is installed in the lower portion of the smoke hole (51) to build the underground yeondae 50 to color the upper portion of the color (A) Shows.

As described above, the underground squadron 50 explodes the smoke cylinder 53 filled with a large amount of high pressure gas by the detonation means 40 when an earthquake occurs, and ejects the high pressure gas through the connecting passage 52 through the airbag stand 20. By continuously forming a high-pressure gas wall throughout the interior, it serves as an assistant to effectively block the long-term seismic waves.

The fume cylinder 53 is a gas wall generated from the explosives for the air bag 21 is instantaneously formed at a point in time when the blocking function is weakened to generate a high-pressure gas at a time to continuously form and reinforce the gas wall Therefore, it is suitable to effectively block the vibration of earthquake with long duration.

Here, the method of drilling the connecting passage 52 may be in communication with the air bag stand 20 by putting the explosives in the lower portion of the fume hole 51 and burst.

On the other hand, as described above, in the anti-vibration method of the present invention, one unit anti-vibration belt line is constructed by a combination of the airbag 20, the underground minefield 30, or the underground generation regiment 50. Note that it is also possible to construct two or three plural arrays of phosphorus.

In addition, the present invention is easy to visually distinguish and identify step by step by applying the explosive gas color (yellow, white, green, etc.) of the explosives for airbags 21, underground mines 32, and underground communication tube 53. .

The present invention as described above is a dust-proof system of the main structure for constructing the anti-vibration belt in the outside of cultural property facilities, factory areas, nuclear facilities, dams, ports, airports, residential complexes, belts by the anti-vibration belt line It is revealed that it can be used as a wide area dust prevention system by constructing it.

Thus, the present invention is simply cut the ground by the rock cutting method by the tensile force, and then loaded with a small amount of airbag explosives (21) in a layer at a predetermined interval therein to build an airbag stand 20, the airbag stand Perforated underground mine (31) along a predetermined line in front of the (20) to load a powerful underground mine 32 in the form of a layer to build an underground mine (30), the detonation means (40) when an earthquake occurs By blocking the seismic waves in the air bag 20 and by the ground mines 30 to actively interfere with and offset the seismic waves,

First, the present invention, which introduces an offensive anti-vibration concept that actively opposes seismic force away from the conventional seismic seismic concept, forms a beltline step by step, blocks and offsets the seismic force, thereby protecting specific areas and structures (B). The main effect is dustproof and dustproof,

Second, it is easy to construct and significantly reduce the construction cost by having a structure to load explosives by drilling deeply into the ground without drilling the ground.

Third, since the anti-vibration belt is formed in the form of perforation, there is an advantage in that the impact on the terrain and geology in construction is small and the space required is minimal.

Fourth, it is effective to make dustproof and dustproof by constructing anti-vibration belt afterwards for cultural property facilities or existing structures that are not designed for earthquake-proof, or constructing a regional anti-vibration system in the region or the whole city.

As described above, the explosion-proof dustproof method by cutting the ground of the present invention is not only to excavate the ground, but to drill the explosives by drilling the ground, so that the construction is easy and significantly reduce the construction cost, and actively seismic force It is very useful to block and offset seismic forces against.
