本考案は800〜1000mmの比較的小口径の圧力パ
イプ継手部の水圧試験装置に関する。[Detailed Description of the Invention] The present invention relates to a hydraulic testing device for pressure pipe joints having a relatively small diameter of 800 to 1000 mm.
上下水、工業用水等の水路用圧力パイプは、布
設工事後通水前に、継手部の接合の良否を確認す
る必要があり、マンホールから水圧試験装置をパ
イプ内に搬入してパイプ内で組み立てて、移動し
ながら逐次継手部の水圧試験を行なう。 Pressure pipes for waterways, such as water, sewage, and industrial water, need to be checked to see if the joints are properly connected after installation work and before water is passed through the pipe.A water pressure testing device is carried into the pipe through the manhole and assembled inside the pipe. Then, while moving, perform water pressure tests on the joints one after another.

を形成させる水圧試験装置は、加圧部の水密保持
が良好で１〜10Kg／cm2の比較的高い圧力の水圧試
験ができ、作業性も秀れている。 As this water pressure test device, an endless water-stop rubber band with a cross section with two protruding protrusions near both ends of the upper surface of a rectangular flat plate was placed so that the protrusions were in contact with the inner surface of the pipe on both sides of the pipe joint. This water-stop rubber band is pressed against the inner surface of the pipe with a hydraulic cylinder via a pressure plate to form a pressurized part for the water pressure test.The water-tightness of the pressurized part is maintained well, and the water-tightness of the water-tight rubber band is 1 to 10 kg/ It can perform water pressure tests at relatively high pressures of cm 2 and has excellent workability.
しかしながら、この水圧試験装置は止水ゴムバ
ンドを内側からパイプ内面に圧着させるための油
圧シリンダが放射状に配列されており、小口径の
場合この装置の設置箇所の手前側から向う側への
人の往来が極めてむつかしいという欠点がある。
すなわち、管路のマンホールは約200ｍ毎にしか
設置されていないし、水圧試験装置を分解するの
は容易ではない。 However, this water pressure testing device has hydraulic cylinders arranged radially to press the water-stop rubber band onto the inner surface of the pipe from the inside, and in the case of small-diameter models, there is a large amount of traffic from the front side to the opposite side of the installation location of this device. The disadvantage is that it is extremely difficult.
In other words, manholes are only installed approximately every 200 meters in the pipeline, and it is not easy to disassemble the water pressure test equipment.
従来この対策として、水圧試験装置を転倒可能
に構成したものが工夫されていたが、水圧試験の
作業中は転倒できず、また、転倒できる時でもそ
の作業は容易でなく、不満足であり、往来の必要
あるときはいつでも簡易に往来できることが望ま
しい。 Conventionally, as a countermeasure against this problem, the hydraulic testing equipment was designed to be able to be tipped over, but it cannot be tipped over during the hydraulic testing process, and even when it can be tipped over, the work is not easy, unsatisfactory, and traffic It is desirable to be able to easily come and go whenever necessary.

As shown in FIG. 1, the pressure pipe is connected by fitting a rubber packing onto the spigot 2 and inserting it toward the socket. The rubber packing 3 is rolled and crushed as shown in FIG. 2, and is joined while maintaining airtightness and watertightness. FIGS. 2 and 3 show a hydraulic test device for large-diameter pipe joints, and FIG. 4 shows an embodiment of the hydraulic test device for small-diameter pipe joints according to the present invention.
