What are the installation specifications for PVC drainage pipes

After the home decoration is completed, there are often some materials that are not used, throw away and feel a little wasteful, after all, it is also purchased with the decoration budget, we are human witty, good at thinking, often have some good thinking, make ideas works, today we want to ** is to use a pvc pipe to make dozens of good-looking furniture, maybe you will say useless, to show you another form of coffee table made in this way:

As long as you are careful, as long as you are not lazy, such a storage tool is very easy to complete, growing vegetables on the balcony is not only very practical, but also has the advantage of being very good-looking, transforming the PVC pipe into the shape shown below, sprinkling seeds in each tube, both vegetables to eat, and can be decorated, isn't it killing two birds with one stone?

It is made of PVC pipe connectors and can be used to store hair dryers and curling irons, which is very practical.

Maybe you feel that these are too complicated, how about this, it's very simple! Most of the children use this kind of weaving.

Decorate the skeleton with a chair cloth, and a cute and cute children's chair is immediately made!

Make a small groove in the bottom of the PVC water pipe to hang a goblet for a goblet.

Drain glue for connection. The adhesive must be shaken well before use. The pipe and socket parts must be cleaned, the smaller the gap between the sockets, the better the joint surface with an abrasive cloth or saw blade, the socket is thinly and evenly brushed with glue, and the socket part is brushed twice with glue, and the glue is inserted in place after 40 60s after the glue is dry, and attention should be paid to the appropriate increase or decrease of the glue drying time according to climate change.

It is strictly forbidden to get wet during bonding, the pipeline must be placed flat in the ditch after it is in place, and the backfill will start 24h after the joint is dry, and the pipe will be filled tightly with sand when backfilling, and a large number of backfills will be carried out after leaving the joint part.

Use products from the same manufacturer. When the UPVC pipe is sleeved with the steel pipe, the connection of the steel pipe must be wiped clean and glued, and the UPVC pipe must be heated and softened (but not scorched) and then inserted on the steel pipe and cooled. If the pipe is damaged in a large area, the whole section of the pipe needs to be replaced, and the method of replacing the pipe with double socket connectors can be adopted.

The solvent method can be used to deal with leakage at the solvent bond.

Drain the water in the pipes.

At this time, the water in the pipe is drained first, and a negative pressure is formed in the pipe, and then the adhesive is injected into the pores of the leakage site. Due to the negative pressure in the tube, the adhesive will be drawn into the pores to prevent leakage. The nest bonding method is mainly aimed at the leakage of small holes and joints in pipes.

At this time, the pipe of the same caliber with a length of 15 to 20cm is selected, it is cut longitudinally, the inner surface of the casing and the outer surface of the pipe to be repaired are haired according to the method of bonding joints, and the sleeve is attached to the leakage after gluing. The glass fiber method is to prepare a resin solution with epoxy resin reinforcing agent, impregnate the resin solution with glass fiber cloth, evenly wrap it on the surface of the pipe or joint leakage, and become glass fiber reinforced plastic after curing.

The drainage pipe usually uses PVC pipe, and the high-rise drainage pipe is mainly double-walled hollow or spiral noise reduction, and the adhesive and water pipe must be made of good materials, so as to achieve no peculiar smell, no water leakage, and the best flame retardant.

The horizontal drainage pipe should have a slope, usually not less than 1%, and pay attention to the drainage slope when laying the drainage pipe, which will help to discharge the sewage immediately. If there is more than one sanitary appliance in one drainage pipe, an inspection port should be added, and the inspection port is usually 1 meter above the ground, and the center of the H pipe is about one meter. The main purpose of the checkpoint is to detect and quickly troubleshoot obstacles.

Precautions for drain pipe installation.

The installation of toilet water pipes should be laid according to the direction of the water, generally horizontal and vertical, as far as possible 2 pipes do not cross, if the cross to build a bridge, the hot and cold water pipes are separated and kept at a certain distance, the left and right positions of the bathing water mixing valve are correct and installed in the middle of the bathtub, the height is best between meters and meters, and the installation of water heaters and the inlet and outlet of the washing machine should be reserved for the position, so as to achieve a scientific and reasonable layout.

The installation of toilet water pipes, the general water pipes go to the top and do not go to the ground, the cold and hot water outlets must be horizontal, generally the left is hot and the right is cool, the pipeline laying needs to be horizontal and straight, and the layout direction should be safe and reasonable. The position of the pipe clamp and the slope of the pipe should meet the requirements of the specification. All kinds of valves should be installed in the correct and flat position, which is easy to use and maintain.

Answer the basic requirements 1, the quality of water supply and drainage pipes and pipe fittings must meet the standard requirements, and the drainage pipes should be made of rigid PVC drainage pipes and pieces. 2. Before construction, it is necessary to check whether the original pipeline is unblocked, and then carry out construction, and then check whether the pipeline is unblocked after construction. The concealed water supply pipeline should be inspected by the water, and the newly installed water supply pipeline must be pressurized in accordance with the relevant regulations, and there should be no leakage, and the inspection can only enter the next process of construction.

3. The drainage pipeline should be temporarily sealed before construction to avoid debris entering the pipeline. 4. For the installation of water supply pipes with an outer diameter of less than 25mm, pipe clamps should be set at 100mm of corners, water meters, faucets or angle valves and pipeline terminals, and the installation of pipe clamps must be firm. The pipeline should be connected with threads and exposed threads at its connection, and it should be fixed with pipe clamps in time after installation, and there should be no loosening between the pipe and the pipe fittings or valves.

5. The position of the installed valves should meet the design requirements and be easy to use and maintain. 6. The connections of all joints, valves and pipelines should be tight, and there should be no leakage, and the slope of the pipeline should meet the requirements. 7. All kinds of pipelines shall not change the original nature of the pipelines.

Acceptance requirements and methods 1, the pipeline arrangement should meet the design requirements, the pipeline installation should be fixed firmly, no loosening, the faucet, valve installation is smooth, the opening is flexible, the water outlet is smooth, and the water meter is operating normally. Acceptance by visual inspection and hand feel. 2. There should be no leakage at the connections between pipes and appliances, pipes and pipelines.

The method of water passing, visual inspection and hand feeling is used to check whether there is leakage. 3. The installation of water pipes shall not be close to the power supply, and the distance between water pipes and gas pipes shall not be less than 50mm. Check with a steel tape measure.

Analysis of acceptance criteria for water supply and drainage pipelines: The installation of water supply and drainage pipelines should meet the design requirements to ensure smooth water intake and drainage. There should be no water leakage at the junctions of pipes and appliances, pipes and pipe joints.

Before draining the pipeline, first check whether the original pipe is unblocked, and confirm that it is unblocked before proceeding with construction. After the installation of the new water inlet pipe and drainage pipe, the pressurized water test must be carried out in accordance with the relevant regulations, and there should be no leakage, and the pipe can be sealed or enter the next process construction only after the inspection is qualified.

Ask what is the slope of the drain.

Be sure to do a good job of drainage. 1. The water pipe is a hidden project, and the size of the water pipe must be considered more comprehensively when arranging the size of the water pipe, or it is not easy to use in the later stage, and it is more troublesome to maintain. Toilet drain pipe size: The inner diameter of the sewer pipe is 100mm to 3000mm, and the length is 30mm to 200mm.

2. DN50 is used in the toilet as long as it is not a toilet, and DN100 is used for the toilet and the pipeline after the toilet. Sewer pipes, kitchen and bathroom sewage can not be discharged together, kitchen sink with DN50, floor drain with DN50, together with DN75. The drain connected to the toilet bowl should be DN110.

The unique double corrugated structure effectively improves the external pressure strength of the product, and the drainage system will not be affected by the external pressure deformation. The choice of bathroom drain pipe size must not be sloppy, you must know that there is no reasonable design, and the water discharged from the water pipe will flow slowly when we use it, so it is very inconvenient to use, so it is very important to choose the size of the bathroom drain pipe.

With the continuous development of the modernization process, people's requirements for materials are getting higher and higher, from the simplest requirements for being able to possess materials in the past, to the high requirements for other aspects such as designs. In terms of housing construction, in order to meet people's requirements for the appearance of the building, the indoor drainage system has been more and more widely used, PVC drainage pipe is an alternative to the traditional drainage pipe, it has strong pressure resistance, and also has the effect of improving the indoor net height, let's take a look at the details of the PVC drainage pipe installation specification. 

1. General construction requirements for PVC pipes

1) the design of the pipeline turning determines whether the tee and the elbow are provided with the structural type of pushing pier and pier, if you want to set up the pier of pipeline, its back should be close to the thick soil, do not install it on the loose soil, if the back of the pier does not have thick soil, measures should be taken to ensure the stability of the pier. And a rubber sheet cushion should be set between the pier and the pipeline, and its function is to protect the pipeline and prevent the destruction of the pipeline.

2) The radius of curvature of the pipe bending should be within the range of 300 times the radius of the PVC pipe.

3) The pipeline through the wall should be provided with a reserved hole or a casing installed, and the pipe should be filled with oil hemp in the raceway and casing, and the pipeline can not have an interface within the scope of the casing.

4) In the well chamber set up on the pipeline, the bottom of the well should be waterproofed, the hook joints of the well wall should be plastered, and the connection between the well wall and the pipeline should be sealed, which is to prevent groundwater infiltration.

5) The pipeline can be used rubber ring interface or RR connection, adhesive interface or T-S connection, flange connection and other types, and the pipe with an outer diameter of 63-315mm can be used for rubber ring interface or RR connection; Pipes with an outer diameter of less than 160 mm can be used for bonding interfaces or T-S connections; The connection between rigid PVC pipes and cast iron pipes or other pipes is generally connected by flanges.

2. Construction specifications for PVC pipeline installation

1) The general laying process of the pipeline is divided into five steps, the first step is to put the pipe into the trench, the second step is to interface, the third step is partial backfilling, the fourth step is pressure testing, and the last step is full backfilling. When putting the pipe into the groove, it can only be carried out when the conditions do not allow and the pipe diameter is not large, when the conditions are met, the 3 pipes are connected on the groove, and then smoothly put into the groove.

2) When laying water supply pipelines in trenches, if the design does not stipulate that other materials must be used for the foundation, they should generally be laid on the undisturbed original soil.

3) After the pipeline is installed, the cushion blocks used in laying the pipeline should be removed in time.

The wide application of PVC drainage pipe not only solves the problem of indoor water supply very well, but also makes the building beautiful outside, and the PVC drainage pipe is very environmentally friendly, the interface can be connected by a variety of methods, the construction method is simple, the operation is convenient, and the installation efficiency is high. The installation specifications of PVC drainage pipes mentioned in this article above, if you want to install PVC drainage pipes, you can take a look. Note that when purchasing PVC drainage pipes, it is necessary to check whether its quality is qualified, and unqualified drainage pipes are resolutely not used.
