본 발명은 토목공사시의 흙탕물 흡인 압송, 매립공사 및 준설공사시의 모래, 자갈 등의 흡인 압송 또는 고입자물질을 피소제체(被掃除體)에 분사하여 소제하는 등에 사용되는 내마모성 호스에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to abrasion-resistant hoses used for sucking and pumping muddy water during civil works, sucking and pumping sand, gravel, etc. during dredging and dredging, or spraying high particle materials onto a body to be cleaned.

이상과 같은 용도에 사용되는 호스는 고압의 흡인 또는 압송의 압력에 견딜 수 있어야 하고, 흡인 또는 압송되는 입자(흙, 모래, 자갈 및 고강도세입자물 등)와의 마찰에 의한 내마모성이 강해야 할 뿐만아니라, 그 중량이 가능한 한 가볍고, 굽힘성을 좋게 하여 그 작업성이 우수한 내마모성 호스를 제공함을 목적으로 하는 것이다.The hoses used for the above applications must be able to withstand the pressure of high pressure suction or pressure feeding, and must be resistant to abrasion by friction with the particles sucked or pumped (such as soil, sand, gravel and high-strength tenants), It is an object to provide a wear resistant hose whose weight is as light as possible and its bendability is good, and its workability is excellent.

종래에 위와같은 용도에 사용되는 내마모성 호스는 제3도(일본 실용신안공보소53-40737 : 1978. 10. 2)에 도시된 것과 같이 관체 내면에 보강용 고무피복 직포층(이하 강력포라 함)을 형성하고, 그 외주면에 고무가류 온도와 친화성이 없는 강선(피아노 선)을 감아붙이면서 고무 호스층을 형성하는 동시에 그 외주에는 다시 상기의 강력포를 여러겹 감아서 되거나, 혹은 상기 호스의 외주에 나타나는 요입부에 강력처리한 마사포 등을 감아서 되는 것이 보통이다. 그러나 상기 호스의 내층을 형성하는 강력포는 마모되면서 강력포를 형성한 섬유올이 표출되어 내부로 흡인 또는 압송되는 입자들의 흐름을 적지 않게 저해하는 동시에 내외층을 형성한 강력포는 호스의 굴곡시에 호스벽의 신축을 저해하여 유연성(굽힘성)이 아주 나쁘고, 또 내압력을 강화시키기 위하여서는 보강선의 간격을 가능한 한 좁혀야 하는데 이는 호스의 굽힘성을 더욱 저해시킬 뿐만아니라 호스의 중량을 더욱 가중시키는 것이므로, 그 작업성이 좋지 못하였다.Conventionally, the wear-resistant hoses used for the above-mentioned applications include a rubber coated woven fabric layer (hereinafter referred to as a strong fabric) on the inner surface of a pipe as shown in FIG. 3 (Japanese Utility Model Publication No. 53-40737: Oct. 2, 1978). Form a rubber hose layer by winding a steel wire (piano wire) having no affinity with rubber vulcanization temperature on the outer circumferential surface thereof and at the same time, the outer circumference again wraps the above-mentioned heavy cloth or It is common to wrap strong masa cloth, etc., in the recess in the outer periphery. However, the strong fabric forming the inner layer of the hose is worn out, while the fiberol forming the strong fabric is exposed to a significant inhibition of the flow of the particles sucked or transported into the inner and at the same time forming the inner and outer layers of the rigid fabric is the bending of the hose The flexibility of the hose wall is hampered by the expansion of the hose wall, and in order to strengthen the pressure resistance, the spacing of the reinforcement wire should be as narrow as possible, which not only hinders the bendability of the hose but also increases the weight of the hose. As it was weighted, the workability was not good.

본 발명은 상기와 같은 종래의 문제점을 해결하기 위하여 제안되는 것이다.The present invention is proposed to solve the above conventional problems.

본 발명의 실시예를 첨부도면에 의하여 설명하면, 제1도는 본 발명에 따르는 내압 호스의 단면도이고, 제2도는 본 발명에 따르는 내압 호스의 구성요부를 절제한 사시도이다.An embodiment of the present invention will be described with reference to the accompanying drawings, Figure 1 is a cross-sectional view of the pressure resistant hose according to the present invention, Figure 2 is a perspective view of the main portion of the pressure resistant hose according to the present invention.

본 발명의 제1도에 표시되는 것과 같이 본 발명의 호스(1)는 내마모성이 우수한 고무로 내층(2)을 형성하고, 그 외주면에 강력섬유사로 엮은 보강층(3)을 형성하면서 그 외주면에 연질의 합성수지층(4)을 형성하는 동시에 이 외주면에 경질 합성수지로 되는 보강선재(5)을 감아서 되는 내압호스에 관한 것이다.As shown in FIG. 1 of the present invention, the hose 1 of the present invention is soft on its outer circumferential surface while forming an inner layer 2 of rubber having excellent abrasion resistance, and forming a reinforcing layer 3 woven with strong fiber yarn on the outer circumferential surface thereof. The pressure-resistant hose which forms the synthetic resin layer 4 and winds the reinforcement wire 5 which becomes a hard synthetic resin on this outer peripheral surface.

본 발명의 실시는 제2도에 표시하는 것과 같이 실시하고자 하는 호스(1)의 내경에 해당하는 외경을 가진 만드레일 상에 필요한 두께로 되는 고무대를 나선상으로 감은 내층(2)은 가류공정을 거쳐 형성하고, 그 외주면에는 보강사(비니론 또는 나이론 등)로 엮은 보강층(3)과 견고하게 결착되게 연질의 합성수지대를 나선상으로 감아 합성수지층(4)을 형성하는 동시에 경질 합성수지로 되는 보강선재(5)를 나선상으로 감아붙혀서 되는 것이다.In the practice of the present invention, as shown in FIG. 2, the inner layer 2 spirally wound with a rubber band having a thickness required on a mandrail having an outer diameter corresponding to the inner diameter of the hose 1 to be implemented is subjected to a vulcanization process. Reinforcement wire which is formed through the outer circumferential surface and spirally wound the soft synthetic resin band spirally so as to be firmly bound with the reinforcing layer (3) woven with reinforcement yarns (vinyron or nylon, etc.) to form a synthetic resin layer (4). This is done by winding (5) spirally.

본 발명의 실시에 있어서 경질 합성수지로 되는 보강선재(5)의 사용은 호스의 중량을 크게 감소시킬 뿐만아니라, 내압력에 있어서도 종래의 강선에 뒤지지 않게 한 것이다.The use of the reinforcing wire 5 made of hard synthetic resin in the practice of the present invention not only significantly reduces the weight of the hose, but also keeps up with the conventional steel wire in the pressure resistance.

본 발명의 내마모성 호스는 내층(2)의 내면이 평활하게 형성되어 호스(1)의 통과물을 방해하는 일이 일어나지 않으므로 그 통과물에 의한 마모를 최대한 억제할 수 있게 되고, 또 호스(1)의 내층(2)은 그 외주면에 강력한 보강사로 엮은 보강층(3), 연질 합성수지층(4)의 피복층 및 경질 합성수지의 보강선재(5)를 감아붙이고 있으므로, 내압력이 강한 동시에 그 중량을 최대한으로 경감시켰을 뿐만아니라, 가장 좋은 굽힘성을 얻을 수 있는 것이므로, 토목공사, 매립공사, 준설공사 및 연마청소 등의 작업성이 우수한 내압 호스를 제공하는 것이다.In the wear resistant hose of the present invention, since the inner surface of the inner layer 2 is smoothly formed so as not to interfere with the passage of the hose 1, the wear of the passage can be suppressed to the maximum, and the hose 1 The inner layer 2 is wound on the outer circumferential surface of the reinforcing layer 3, the coating layer of the soft synthetic resin layer 4, and the reinforcing wire 5 of the hard synthetic resin. It is possible to provide a pressure resistant hose excellent in workability such as civil engineering work, reclamation work, dredging work, and polishing, since it is not only reduced, but also obtains the best bendability.
