이하 본 발명에 따른 작용을 첨부도면에 의거하여 상세히 설명한다.Hereinafter, the operation according to the present invention will be described in detail with reference to the accompanying drawings.

첨부도면 도1 내지 도6에 도시된 바와 같이 지중케이블보호관(20)의 상하면에 상부파형보호판(30)과 하부파형보호판(40)을 밀착시키게 되면, 상부파형보호판(30)과 하부파형보호판(40)에 형성된 관삽입부(32)(42)로 지중케이블보호관(20)의 상하면이 끼워지게 되는데, 이때 상부파형보호판(30)과 하부파형보호판(40)의 골부위(33)(43)에 형성된 볼트체결공(34)(35)(44)(45)의 구멍중심을 수직으로 일치시킨 상태에서 와셔(94)가 끼워진 내부볼트(52)를 볼트체결공(34)(35)(44)(45)으로 삽입하게 되면, 내부볼트(52)가 볼트체결공(34)(35)(44)(45)을 통해 하단으로 돌출된다.As shown in FIGS. 1 to 6, when the upper waveform protection plate 30 and the lower waveform protection plate 40 are brought into close contact with the upper and lower surfaces of the underground cable protection tube 20, the upper waveform protection plate 30 and the lower waveform protection plate ( The upper and lower surfaces of the underground cable protection tube 20 are fitted into the pipe insertion portions 32 and 42 formed in the 40, wherein the bone portions 33 and 43 of the upper waveform protection plate 30 and the lower waveform protection plate 40 are inserted. In the state where the hole centers of the bolt fastening holes 34, 35, 44 and 45 are vertically aligned with each other, the inner bolt 52 into which the washer 94 is fitted is bolted holes 34, 35 and 44. When inserted into the (45), the inner bolt 52 is projected to the bottom through the bolt fastening holes 34, 35, 44, 45.

이후 하단으로 돌출된 내부볼트(52)의 하단부에 또 다른 와셔(96)를 끼운 다음 내부너트(50)를 결합하여 조이게 되면, 상부파형보호판(30)과 하부파형보호판(40)이 서로 가까워지면서 지중케이블보호관(20)의 상하면에 밀착된다.After inserting another washer 96 to the lower end of the inner bolt 52 protruding to the bottom and then tightened by combining the inner nut 50, the upper waveform protection plate 30 and the lower waveform protection plate 40 is close to each other It is in close contact with the upper and lower surfaces of the underground cable protection pipe (20).

그 다음 상부외측커버(60)와 하부외측커버(70)에 각각 형성된 위치결정돌기(69)(79)가 상부파형보호판(30)과 하부파형보호판(40)의 산부위(36)(46)에 각각 형성된 위치결정구멍(37)(47)에 끼워지도록 상부외측커버(60)와 하부외측커버(70)로 상부파형보호판(30)과 하부파형보호판(40)을 덮개 되면, 상부외측커버(60)와 하 부외측커버(70)에 형성되어 있는 플랜지(62)(64)(72)(74)가 밀착되면서 플랜지(62)(64)(72)(74)에 형성된 관통구멍(66)(68)(76)(78)의 중심이 일치된다.Then, the positioning projections 69 and 79 formed on the upper outer cover 60 and the lower outer cover 70 respectively are acid portions 36 and 46 of the upper waveform protection plate 30 and the lower waveform protection plate 40. When the upper waveform protection plate 30 and the lower waveform protection plate 40 are covered with the upper outer cover 60 and the lower outer cover 70 so as to be fitted into the positioning holes 37 and 47 formed in the upper portion, the upper outer cover ( 60 and the through holes 66 formed in the flanges 62, 64, 72 and 74 while the flanges 62, 64, 72 and 74 formed in the lower outer cover 70 are in close contact with each other. The centers of (68), 76, and 78 are coincident.

이후 관통구멍(66)(68)(76)(78)으로 외부볼트(82)을 삽입하고 외부너트(80)와 결합하여 조이게 되면, 상부외측커버(60)와 하부외측커버(70)가 결합된 상태를 유지하게 된다.Then, when the outer bolt 82 is inserted into the through holes 66, 68, 76, and 78 and tightened by being coupled with the outer nut 80, the upper outer cover 60 and the lower outer cover 70 are coupled. Will remain intact.

한편, 위와 같이 조립된 구조물을 지중에 매설하게 되면, 지중케이블보호관(20)의 외측에 밀착되어 있는 상·하부파형보호판(30)(40)과 상·하부외측커버(60)(70)에 의해 지중케이블보호관(20)의 강도가 보강되어 지반침하에 의한 지중케이블보호관(20)의 파손을 방지할 수 있게 된다.On the other hand, when the structure assembled as described above is buried in the ground, the upper and lower waveform protection plate 30, 40 and the upper and lower outer cover 60, 70 is in close contact with the outer side of the underground cable protection tube (20). As a result, the strength of the underground cable protective tube 20 is reinforced to prevent breakage of the underground cable protective tube 20 due to ground subsidence.

즉, 상·하부외측커버(60)(70)에 수직토압이 작용되는 경우 우선 토압을 상·하부외측커버(60)(70)가 견디고, 상·하부외측커버(60)(70)의 내측에 위치되어 있는 상·하부파형보호판(30)(40)으로 압력이 전달되는데, 이때 상·하부파형보호판(30)(40)이 내부볼트(52)와 내부너트(50)에 의해 결합되어 있기 때문에 상하방향으로 움직일 수 없게 되고, 상·하부외측커버(60)(70)에 형성되어 있는 위치결정돌기(69)(79)에 걸려 있기 때문에 길이방향으로도 움직일 수 없어 압력이 상·하부파형보호판(30)(40)의 전체로 고르게 전달되면서 압력을 견디게 된다.That is, when vertical earth pressure is applied to the upper and lower outer covers 60 and 70, first, the upper and lower outer covers 60 and 70 endure the earth pressure, and then the inner and upper outer covers 60 and 70 are inward. Pressure is transmitted to the upper and lower waveform protection plates 30 and 40 positioned at the upper and lower waveform protection plates 30 and 40, and the upper and lower waveform protection plates 30 and 40 are coupled by the inner bolt 52 and the inner nut 50. Because of this, it cannot move in the vertical direction, and because it is caught in the positioning projections 69 and 79 formed on the upper and lower outer covers 60 and 70, the pressure cannot be moved even in the longitudinal direction. Evenly transmitted to the whole of the protective plate 30, 40 to withstand the pressure.

특히 지중케이블보호관(20)의 상하면에 밀착되어 있는 상부파형보호판(30)과 하부파형보호판(40)은 탄성을 지니기 때문에 지중케이블보호관(20)과의 사이에 약간의 슬립을 발생시켜 지중케이블보호관(20)의 파손을 방지하게 된다.In particular, since the upper waveform protection plate 30 and the lower waveform protection plate 40 in close contact with the upper and lower surfaces of the underground cable protection tube 20 have elasticity, a slight slip is generated between the underground cable protection tube 20 and the underground cable protection tube 20. The breakage of the 20 is prevented.

그리고, 상부파형보호판(30)과 하부파형보호판(40)이 판재를 정형파 형태로 절곡하여 놓은 것과 같은 꼴로 형성되어 있기 때문에 내구력에 의해 가벼워 시공이 간편하게 되고 이동 및 취급이 간편하게 된다.In addition, since the upper waveform protection plate 30 and the lower waveform protection plate 40 are formed in the same shape as the plate member is bent in the form of a square wave, it is light due to the durability and construction is simple and the movement and handling are simple.

이상에서 설명한 바와 같은 본 발명은 지중케이블보호관의 상하부를 정형파 형태로 절곡된 상·하부파형보호판이 덮고 있고, 상·하부파형보호판의 외측은 상·하부외측커버로 덮이는 구조로 되어 있기 때문에 토압에 견디는 힘을 증대시켜 지반침하로부터 지중케이블보호관을 보호할 수 있는 효과가 있다.According to the present invention as described above, the upper and lower waveform protection plates bent in the form of a square wave cover the upper and lower portions of the underground cable protection tube, and the outer and upper waveform protection plates are covered with the upper and lower outer cover. Therefore, it is effective to protect the underground cable sheath from ground subsidence by increasing the force to withstand earth pressure.

더 나아가서 본 발명은 상·하부파형보호판이 얇은 두께로 형성되어 있기 때문에 경량화가 가능하여 이동 및 취급이 간편하게 되는 효과가 있으며, 상·하부파형보호판이 내부볼트와 내부너트에 의해 결합되어 있고, 상·하부외측커버에 형성된 위치결정돌기에 걸리는 구조로 되어 있기 때문에 상·하부파형보호판의 상하방향유동 및 길이방향 움직임이 저지되어 구조적인 강성이 크게 향상되는 효과가 있다.Furthermore, in the present invention, since the upper and lower waveform protection plates are formed in a thin thickness, it is possible to reduce the weight and simplify the movement and handling, and the upper and lower waveform protection plates are combined by the inner bolt and the inner nut, The structure is applied to the positioning projection formed on the lower outer cover, thereby preventing the vertical flow and the longitudinal movement of the upper and lower waveform protection plates, thereby improving the structural rigidity.
