Due to the flexible connection of grooved HDPE ultra-silent drainage pipe, the construction strength and process complexity of the pressure ring, such as PVC drainage pipe connection, the sleeve of indoor socket plastic drainage pipe, and the bonding sub-item can be. Although the connection method is different, the basic construction process is the same. The labor required for installation is also basically the same.
Therefore, the indoor UPVC drainage quota bonding part can be applied, of course, the corresponding accessories of the quota installation content must be replaced by the grooved HDPE ultra-quiet drainage pipe, that is, the price needs to be regrouped and intervened.

Question 1: What is the quota of PVC drainage pipe sleeve Install a professional water supply and drainage engineering plastic drainage pipe sub-item.
Question 2: What is the quota of the buried PVC drainage pipe sleeve Shandong 96 quota set 2-3-122, 2-3-121, 2-3-120 and other sub-items.
Question 3: What quota is applied to the inspection port of the drainage pipe Chapter 8 of the cleaning port has a special quota subheading, calculated according to the number, the inspection port is mainly the drainage riser, and the auxiliary pipe fittings belonging to the pipeline are not separately calculated and included in the pipeline subheading.
Question 4: How to set the quota of UPVC drainage pipe There is a plastic pipe installed in the water supply and drainage quota (the quota is applied according to the connection method).
Question 5: What is the scope of outdoor sewage and rainwater drainage pipeline engineering Civil engineering or water supply and drainage, what quota belongs to water supply and drainage engineering, set of the fifth item of plastic pipe installation under the first chapter of pipeline installation (6) outdoor socket plastic drainage pipe installation (parts bonding) sub-item or (7) outdoor double-wall spiral water pipe installation sub-item, according to the actual selection of materials and pipe diameter selection.
Question 6: What quota should be set on the roof downpipe Apply the "Indoor Pipe" in the eighth volume of "Water Supply and Drainage Pipe Installation", and insert cast iron rainwater pipe (asbestos cement interface), cast iron rainwater pipe (cement interface), steel pipe rainwater pipe (welded), plastic rainwater pipe (bonding) OK!
Question 7: What is the quota for the earthwork excavation of the building drainage pipeline If it is building drainage, the first chapter of the construction project quota is applied to the earthwork engineering, and the specific calculation method is clearly stipulated in the quota.
Question 8: What is the quota of the reinforced concrete drainage pipe reinforced concrete socket pipe, which can be applied to the municipal tour quota Shen Chunhe. Flexible rubber ring interface is adopted, and the sand pants are cracked stone foundation.
The foundation angle is determined according to the buried depth of the pipeline, and the buried depth in the general plant area is not very deep, and the 120° sand and gravel foundation can be used. The main items of the subheadings generally have slotting, precipitation, downpipe, and backfilling. There are also a number of measure projects.
Question 9: What is the quota for the installation of rainwater pipe fittings Rainwater pipe fittings are generally included in the rainwater pipe quota subheading, but the rainwater inlet needs another subheading.
Question 10: How to set the quota for the sewer pipe Personal experience: Sometimes I am a set of sporadic bricklaying + sporadic plastering + sporadic fast material surface layer, so there is still a certain gap between the set and the actual (low), and it is the only way to go formal.
There are also times when it is calculated directly according to the "root", supplementing the quota, and the actual **, but in this way you have to know the basis for the composition of the comprehensive unit price (that is, if someone asks you, you have to say that the unit price is ugly).

Hello dear! Glad for your question! Shaanxi Province quota pp ultra-silent drainage pipe how to set:
1) When installing the socket PP ultra-silent drainage pipe and installing the pipeline, a special cutter must be used to cut, and the cross-section is perpendicular to the axis. The distance between the two socket flexible connection ports is recommended to be no more than 3m, and the length adjustment can be compensated by using the depth of the socket, but the length of the pipe inserted into the bottom of the pipe fitting shall not exceed 8mm in summer and 12mm in winter. Wheel rough shelter (2) socket plus screw pressure PP ultra-silent drainage pipe installation, point 1, the use of a special pipe cutting machine (cutting machine or cutter) to cut off the pipe, the nozzle end should be vertical pipe axis.
2. Put the threaded ring, clamp ring and sealing ring on the connected pipe in turn. 3. Insert the head of the pipe into the inner face hole groove of the joint body of the stool (lubricant can be evenly applied to the head of the pipe) 4. Push the pipe to make it and the bottom of the inner groove of the pipe fitting 4mm Lazhou, and start to tighten the threaded ring, so as to achieve the purpose of sealing the connection.

I don't know if you are asking about the water supply and drainage in the installation project or the water supply and drainage in the municipal project, if it is the water supply and drainage in the installation project, so the pipeline installation includes the installation of pipe fittings, and there is no need to set any quota. Of course, there are two situations here, one is that the pipe fittings are included in the fixed base price as a secondary material, and there is no need to calculate the price of pipe fittings, most of them are so, one is that the pipe fitting installation fee has been included, but the material cost of the pipe fittings is not included, it is necessary to calculate the amount of pipe fittings according to the actual price, and enter the cost at the market price, if it is a municipal project, there is no quota of pipelines in the municipal government, and if the installation quota is borrowed, it will be handled according to the installation quota, and there is such a quota in a municipal administration, which generally does not include the installation of pipe fittings, It is necessary to set the corresponding pipe fitting quota, depending on what pipe material, what pipe fittings are used, and apply the corresponding pipe fitting quota.
As for the specific fitting package does not include installation, you have to look at the quota description, and you can also see whether it is included from the content of the quota

Polypropylene silent drain pipe sleeve sub-item:
Apply the plastic drainage pipe socket connection in the water supply and drainage.
PP Silent Drain Pipe Definition:
PP English name: polypropylene The Chinese name is polypropylene, commonly known as Baizhu glue. It is another excellent resin variety developed after nylon, which is a linear polymer with high density, no side chain and high crystalline.
It is a translucent, semi-crystalline thermoplastic, PP (polypropylene) can be divided into isometric PP (polypropylene) and random PP (polypropylene) according to its crystallinity, and the commonly used PP raw material is isometric polypropylene.
PP has excellent comprehensive properties. It has the characteristics of high strength, good insulation, low water absorption, high heat deflection temperature, low density and high crystallinity. It has good solvent resistance, oil resistance, weak acid resistance, weak alkali resistance and other properties.
Polyoxymethylene has high hardness and rigidity, high creep resistance and stress relaxation ability, excellent wear resistance, self-lubrication, and fatigue, which cannot be compared with other engineering plastics.

First of all, make preparations before installation, and count the amount of pipe fittings and pipes used in the material plan in advance to avoid the waste of pipe fittings and pipes that cannot be used.
Secondly, improve the drawings, deepen the design, and draw the installation drawings before installation, so that the manufacturer can produce according to the demand to reduce unnecessary waste.
Thirdly, a reasonable number of pipe fittings are selected, and appropriate pipe fittings are selected in the stage of deepening the design of the bench difference, such as using the characteristics of the ultra-quiet jujube discharge Bipi water pipe floor drain grate and buckle bowl, and the position of the floor drain and the cleaning port is exchanged to replace the cleaning port and save materials. If the PP ultra-silent pipe connected by the Jietong brand socket is used, the socket on the tee can be used as a telescopic compensation on the drainage riser instead of the expansion joint.
This is actually not a fixed concept, because for example, if I fill calcium carbonate, I fill 20% is a modified PP, and I fill 21%, which can also be said to be another modified PP, so I can only say what are the methods of modified PP, and it is too imprecise to ask the types of modified PP. >>>More

Summary. PP particles are polypropylene particles, which can be made of petroleum, coal, PDH, methanol, propane, propylene. At present, the majority of PP made of coal and oil PP are mainly used in China, and PP particles should be called PP slices strictly speaking, but in China, the industry is used to calling PP particles, and it has been inherited. >>>More

Both polypropylene and polyethylene are soft rubbers, but polypropylene is comparatively much harder than polyethylene (you can't bite with your teeth). At present, there are no fanny packs made of these two materials, and I hope you can create them. Polyethylene with EVA glue will be a little softer.
