Abstract

PURPOSE: A plastic water supply pipe and drainage pipe coupler is provided to prevent the leakage of water by tightly coupling a joint between both plastic pipes against water pressure or the collapse of soil. CONSTITUTION: A plastic water supply pipe and drainage pipe coupler is made of solid plastic. A water supply pipe or a drainage pipe(2) is also made of fiber reinforced plastic with many steel rings or fiber reinforced plastic rings. The coupler consists of a recessed portion(4a,5a,6a) and a protruded portion(3a,3b,3c). After an adhesive is coated on a socket of the water supply pipe, the protruded portion is inserted into the recessed portion and bolt holes(2a2) of the rings. Thus, two pipes are tightly connected against water pressure and the collapse of soil.

Description

Plastic water and sewage connections {omitted}

The present invention is a binding material for binding a water pipe that receives a relatively high pressure such as water supply. FIG. 1 is a drawing of the assembled state of the present invention, and a part of FIG. 2-1 and a part of FIG. The water pipe and the water pipe into the socket by fitting the ring bolt hole 2a2 of the formed water pipe into the bolt hole of the ring of the water pipe socket part where another ring is formed, and then fitting the water pipe and the water pipe into the socket. If you press the projecting part) and the toothed part of Figure 3a-1 to match, the coupling is completed.

When the teeth are matched, the key parts of Fig. 2-1 are caught by the teeth so that they do not fall out of each other, and the strong force that does not fall out of each other keeps the water pipe joint from falling under any shock or strong water pressure or leaking.

Here, if you want to loosen the bond because of the wrong assembly process between each other, turn the side of Figure 3a slightly to the side, the key part of Figure 2-1 and the tooth part of Figure 3a-1 are separated and the slippery side of the tooth of Figure 3a-1 Because of the parts, they are separated from each other.

Provides pipe joints that can withstand the strong water pressure of large water and sewage pipes made of plastic materials, large water and sewage pipes formed with rings, or strong external shocks (e.g., soil collapse).

This paper is a part that tightly binds plastic large water and sewage pipes with steel and sewage pipes made of hard plastic synthetic resin to prevent joints from falling out or gaps due to water pressure and external shocks.

With the development of industrial society, water is contaminated and water cannot be used as drinking water, and the river or lake water is purified at the water purification plant and supplied to the intake station through the large water supply pipe, and the water from the intake station is supplied to each household through the small water supply pipe. In addition, the dirty water used in the home is discharged through sewer pipes. In the past, such water and sewage pipes used heavy steel pipes or concrete pipes, which made it difficult to join and lay the pipes. (National leakage rate of 16.1% announced by the Ministry of Environment in 2001, 5,000 won per year) and steel is highly corroded, so it is urgent to replace water pipes.

As an alternative, large plastic sewage and sewage pipes with rings that do not crush under external pressure have emerged.However, the bond treatment between the pipe and the pipe connection causes strong water pressure and water leakage when the joint is impacted such as ground subsidence or collapse around the water pipe. There is.

Conventional techniques include a bolt nut and the like, but the bolt nut has a fast corrosion and takes a long time to perform a fastening operation.

Another method is to tighten the band, but it is difficult to apply to large pipes.

In order to solve this problem, a synthetic resin pipe with a diameter of 100mm or more that is easy to lay and connect is perfectly connected to the joints, such as water pressure or external pressure (soil collapse or earth pressure). The purpose is to maintain good water and sewage pipes.
