Abstract

PURPOSE:To enable a structure to be crushed in a non-impact manner, by a method wherein the pressure of high pressure gas generated in a closed system is utilized. CONSTITUTION:A pressure resistant tube 2 is inserted into a structure to be crushed. Non-compressive liquid is fed through a fluid inflow port 21, and a small cylinder 20 and a pressure resistant tube 2 are full thereof. The feed of liquid is stopped in a state that the outer periphery of the pressure resistant tube 2 is approximately adhered to a hole wall, and the pressure resistant tube 2 is closed. When, with a gas generating device 10 actuated, high pressure gas is generated, a boosting device 30 is actuated, and a stepped piston 32 is slid to pressurize liquid in the small cylinder 20 and the pressure resistant tube 2. This constitution expands the pressure resistant tube 2 to crack the structure.

Description

【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、例えばコンクリート等の構造物を静的に破砕

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a crushing tool for statically crushing structures such as concrete.

〔従来の技術〕[Conventional technology]

従来よりコンクリート等の構造物を破砕するには、大型
重機や水利膨張性破砕剤が使用されている。
BACKGROUND ART Conventionally, large heavy machinery and water-expandable crushing agents have been used to crush structures such as concrete.

前者の大型重機は破砕速度が速く危険性が少なく安全で
ある。しかし機械が大型のため使用場所が限定されたり
騒音が発生するという問題の他、重機そのものが高価で
あり、破砕対象物が小さい場合には破砕物の大きさに比
較して経費が高くついてしまうという欠点がある。
The former type of large heavy machinery has a fast crushing speed and is safe with less danger. However, due to the large size of the machines, there are problems such as limited use space and noise generation, and the heavy machinery itself is expensive, and when the objects to be crushed are small, the cost is high compared to the size of the objects to be crushed. There is a drawback.

これに対し後者の水和膨張性破砕剤は、水利膨張性破砕
剤を水に浸漬した後、穿孔に充填するだけで良い。所定

On the other hand, with the latter hydration-swellable crushing agent, it is sufficient to simply immerse the water-swellable crushing agent in water and then fill it into the perforations. After a predetermined period of time, the crushing agent expands and generates high pressure within the hole to crush the structure, making it possible to easily crush the structure without generating noise. This crushing agent mainly obtains expansion pressure through the water utilization reaction of quicklime, and the expansion pressure is limited to it/cm2, which may be insufficient. Therefore, it is necessary to make a large number of holes in the structure, and the amount of crushing agent used per unit volume of the structure increases, which is not economical. In addition, if quicklime is handled incorrectly, highly alkaline, high-temperature quicklime will spew out, and if it comes into contact with the eyes, there is a risk of blindness, so there are many safety restrictions.

For this purpose, Japanese Patent Application Laid-Open No. 31838/1983 discloses that a rubber tube is inserted into a hole in a structure, and water is forced into the rubber tube using the vaporization pressure of dry ice to expand the rubber tube and crush the structure. A compact device is disclosed.

この装置の圧力源は、ドライアイスの気化圧であるため
その圧力は数十kg/ cm2と低く、増圧ピストンを
使用して増圧しても数百kg/cm2が限度である。破
砕対象物に自由面、即ち破砕された構造物が投出される
面が多い場合には数百kg/ C112程度の破砕力で
も破砕可能であるが、強度の高い構造物や自由面に乏し
い場合は少なくとも1 t/c+n2以上の圧力が必要
とされており圧力不足で実用的でない。この装置の場合
1、ゴム管の外周と孔壁には必ず若干の隙間が存在し、
ゴム管が膨張してもすぐに孔壁を加圧する訳ではない。
Since the pressure source of this device is the vaporization pressure of dry ice, the pressure is as low as several tens of kg/cm2, and even if a pressure booster piston is used to increase the pressure, the limit is several hundred kg/cm2. If the object to be crushed has many free surfaces, that is, the surface from which the crushed structure is thrown, it is possible to crush it with a crushing force of several hundred kg/C112, but if the object is a strong structure or lacks free surfaces. requires a pressure of at least 1 t/c+n2, which is insufficient and impractical. In the case of this device, 1. there is always a slight gap between the outer periphery of the rubber tube and the hole wall,
Even if the rubber tube expands, it does not immediately pressurize the hole wall.

水圧を連続的に加える方法と異なり、ゴム管が膨張し孔
壁に当接するまでの間に気化圧力が緩和されて破砕圧が
減衰してしまう。またゴム管と孔壁が直接接触するため
にその繰り返しによる摩擦劣化が著しく、ゴム管の検査
や交換を頻繁に行う必要があり、簡便、安価とは言い難
い。
Unlike the method of continuously applying water pressure, the vaporization pressure is relaxed and the crushing pressure is attenuated until the rubber tube expands and comes into contact with the hole wall. In addition, since the rubber tube and the hole wall come into direct contact with each other, frictional deterioration due to repeated contact is significant, and the rubber tube must be inspected and replaced frequently, making it difficult to say that it is simple or inexpensive.

FIG. 2 is a diagram showing a cross-sectional state of the structure 11 before the start of the crushing operation using the crushing tool 1 to which the present invention is applied. Perforations 12 are made in advance at important points in the structure 11 to be crushed. The pressure tube 2 is inserted into the perforation 12. When moving from the state shown in FIG. 2 to the crushing work, the pressure release valve 9 and the liquid inlet/outlet 21 are left open, and the hydraulic pump 23 is operated to feed water from the liquid inlet/outlet 21. Then, the pressure tube 2 gradually expands in the radial direction as the internal water pressure increases. When the outer periphery of the pressure tube 2 comes into contact with the hole wall and comes into close contact, the hydraulic pump 23 is stopped and the liquid inlet/outlet 21 is closed. At this time, the different diameter piston 32 is displaced toward the chamber 35 side.

Next, the pressure release valve 9 is closed, and the electric igniter 7 is energized from the external power source 15 through the lead wire 14. When the combustion agent 8 burns, high-pressure combustion gas is generated in the chamber 35, and the different diameter piston 32 slides in the direction of arrow A as shown in FIG. Pressurize the water inside. In this case, the pressure inside the pressure tube 2 is increased to about four times the pressure inside the chamber 35 by the pressure increasing action of the piston 32 of different diameter. The air in this poem 34 is discharged to the outside from the air hole 36.

As shown in FIG. 4, the pressure tube 2 expands in the radial direction as the internal gas pressure increases. This pressure presses the inner wall of the perforation 12, many cracks 13 are generated in the structure 11 from around the perforation 12, the strength is reduced, and the structure 11 is fractured in a self-destructive manner. After the crushing is completed, the valve 9 and the liquid inlet/outlet 21 are opened, the gas in the large diameter cylinder 31 and the water in the pressure tube 2 are released, and the pressurization is released. The crushing work is completed by shrinking and taking out the pressure tube 2.

The pressure tube 2 expands in the radial direction as water pressure increases, while contracting in the longitudinal direction. Immediately after the structure 11 is crushed, a no-load state occurs and the pressure tube 2, ie, the elastic tube 3, attempts to expand further. However, the diameter of both ends of the cylindrical body 4 is regulated, and the curvature of the piano wire constituting the cylindrical body 4 is limited, so the expansion of the elastic tube 3 is also restricted, and after the structure 11 is crushed, it expands excessively. It will not break or explode. Also, before operating the gas generator 10, water is sent into the pressure tube 2 to expand it and fill the gap between the pressure tube 2 and the hole wall, so the pressure generated by the gas generator 10 is applied to the hole wall without attenuation. Added. Furthermore, the cylindrical body 4 alleviates the friction between the counterpressure tube 2 and the high wall, thereby reducing wear and damage on the elastic tube 3. Therefore, extremely high pressure can be applied to perform crushing work efficiently and safely.

The liquid source 23 is connected to the liquid inlet 21 regardless of whether it is electric or manual.

As explained in detail above, the crushing tool of the present invention does not directly apply generated gas to structures, but uses the pressure of high-pressure gas generated in a closed system, so it can destroy structures in a non-impact manner. It can be crushed into pieces. Furthermore, since the gap between the pressure tube and the hole wall is filled in advance, the pressure generated by the gas generator can be applied without attenuation. Therefore, no noise is generated, and large and small structures can be statically, efficiently and safely crushed.
