【考案の詳細な説明】 〔産業上の利用分野〕 本考案は、下水管等の既設管内に空気圧で反転挿入した
紫外線硬化型チューブを内側から紫外線照射により硬化
させて管内面をライニングする場合に好適に使用される
紫外線照射機に関する。[Detailed Description of the Invention] [Industrial field of application] The present invention is applied to a case where an ultraviolet curable tube reversely inserted by air pressure into an existing pipe such as a sewer pipe is cured by ultraviolet irradiation from the inside to line the inner surface of the pipe. It relates to an ultraviolet irradiator that is preferably used.

要するので施工能率が悪いという問題があった。Traditionally, when lining the inner surface of an existing pipe, IN
The S method and HL method were generally adopted. However, since all of these construction methods heat and cure the thermosetting tube with hot water or high-pitched steam, it is easy to control the temperature of hot water and steam in consideration of seasonal temperature changes. In addition, when the thermosetting tube is long, it is difficult to uniformly heat the tube, and since the thermosetting requires a relatively long time, there is a problem that the construction efficiency is poor.

用の紫外線照射機が開発されていないため、次のような
問題があった。In order to deal with such a problem, an uncured UV-curing tube is reversely inserted into the tube by air pressure, and while moving the UV irradiation machine inside the tube, the tube is cured by UV irradiation and the inner surface of the tube is lined. The applicant has already proposed a method (Japanese Patent Application No. 1-343519, etc.). This lining method has various advantages such as no need for troublesome temperature control and a drastic shortening of the curing period, but it has the following problems because a dedicated UV irradiator has not been developed. .
即ち、単に紫外線ランプを取付けただけの紫外線照射機
を使用すると、紫外線がチューブに均等照射されないた

照射機の移動速度を減速し、紫外線照射量（紫外線強
度）を増加してチューブを完全硬化させる必要があり、
この分だけ施工能率が低下し電機エネルギーの使用量が
増大するという問題があった。That is, if an ultraviolet irradiator that is simply equipped with an ultraviolet lamp is used, the ultraviolet rays are not evenly radiated to the tube, so that the curing of the tube becomes uneven, and delamination between the cured and uncured portions may occur. . Therefore, it is necessary to slow down the movement speed of the UV irradiation machine and increase the UV irradiation amount (UV intensity) to completely cure the tube.
There is a problem in that the construction efficiency is reduced and the amount of electric energy used is increased by this amount.
本考案は斯る事情に鑑みてなされたもので、その目的と
するところは、紫外線硬化型チューブの各部に必要最小
限度の紫外線を均一に照射して効率よく硬化させること

に管内面のライニングを行うことができる。When curing the tube reversely inserted into the existing tube using the ultraviolet irradiator having the above-mentioned structure, the eyebolt 7 of the front plate 1 is connected to a tow rope and the power cord 8 is connected to the connector of the rear plate 2. Wire 10 to prevent disconnection while connecting
To the eyebolt 11. Then, the ultraviolet irradiator is inserted from one end of the tube, the motor 23 is driven to reverse the ultraviolet lamp 12 around the reflection plate 18, and the pulling rope is pulled from the other end of the tube to pull the ultraviolet irradiator into the tube. Run inside. UV lamp 12 like this
When the vehicle is run while reversing the direction, the ultraviolet rays emitted from the lamp 12 are directly irradiated or reflected by the ultraviolet reflecting plate and are applied to the entire circumference of the tube almost uniformly, so that there is a partial insufficient curing. There is no worry to remain. Therefore, it is possible to efficiently and economically lining the inner surface of the tube by increasing the traveling speed of the ultraviolet irradiation device and setting the ultraviolet irradiation amount to the minimum amount necessary for curing the tube.

ていればよいのである。In the above embodiment, the cylindrical ultraviolet reflector 18 is attached, but the truncated conical tubular reflector 18a as shown in FIG.
May be attached. When such a reflector 18a is attached, most of the ultraviolet rays emitted from the ultraviolet lamp 12 are reflected obliquely forward, so that the front portion of the tube can be pre-cured by the ultraviolet irradiator, and the curing efficiency is further improved. There is an advantage. The frustoconical cylindrical reflector 18a and the above-mentioned cylindrical reflector 18 do not necessarily have to be attached to the rotating plate 13 so as to rotate, and may be fixed to the connecting bolt 3 or the like, for example. . Further, the ultraviolet reflection plate does not necessarily have to be cylindrical, and for example, as shown in FIG. 8, a curved reflection plate 18b for each lamp 12 may be attached to the rotating plate 13. It suffices that it is provided around the rotation center line of the rotation plate 13 regardless of whether it is a cylindrical reflection plate or an individual curved reflection plate.

However, the rotating plate 13 may be configured to be directly connected to the output shaft of the motor 23 for normal rotation, and It is desirable to mount a controller to make the forward rotation speed or the forward / reverse rotation speed of the rotating plate 13 variable by changing the current so as to easily correspond to the curing conditions of the tube.

効果を奏する。As can be understood from the above description, the UV irradiator of the present invention can evenly irradiate UV light around the entire circumference of the tube that is inverted and inserted into the tube, and cures due to uneven UV irradiation as in the past. Since there is no risk of delamination between the part and the uncured part, it is possible to efficiently and economically lining the inner surface of the pipe by increasing the running speed to the extent that the minimum amount of UV irradiation required for curing is obtained. It has a remarkable effect.
