What is the quota of cast iron telescopic sleeve municipal engineering .

1. There is an installation distance for the set of quotas, or a set of telescopic compensation distance quotas;

Second, the concept of quotas:

The quota is a standard for the amount of resources consumed to complete the qualified products of the unit under the conditions of rational labor organization and rational use of materials and machinery, and it reflects the social productive forces in a certain period.

The level is high and low. For each construction project, the amount of labor is calculated, including basic labor and other labor. Plus the materials for this project, including basic materials and other materials.

The unit price of labor is stipulated locally according to the value of labor of different types of work at that time, and the value of materials is based on the budget formulated by the market in the early stage.

3. Cast iron telescopic device.

A brief introduction:

Cast iron expanders are also called expansion joints and expansion joints.

Compensators, expansion joints. The retractor can be axial within a certain range.

Expansion and contraction, can also overcome the deviation caused by the different axial direction of the pipeline docking within a certain angle, can greatly facilitate the installation and disassembly of the valve pipeline, can be freely expanded and contracted in the allowable expansion amount of the pipeline, once the maximum expansion amount is crossed, it will play a limit to ensure the safe operation of the pipeline. It is mainly to ensure the safe operation of the pipeline, and has the following functions: to compensate for the axial, transverse and angular thermal deformation of the absorption pipeline; Absorb equipment vibration and reduce the impact of equipment vibration on pipelines; Absorption**, subsidence.

The amount of deformation on the pipe.

The quota has an installation distance, and the telescopic compensation distance has a quota.

1. If the drainage cast pipe is installed in the quota water supply and drainage book, including the flexible interface of cast iron pipe fittings, the pipe fittings can be converted. 2. The installation of cast iron pipes for water supply with municipal quota does not include the installation of pipe fittings, and the municipal quota has a special installation sub-item of cast iron pipe fittings.

Cast iron pipe flexible interface sleeve municipal quota cast iron pipe fittings subheading.

8-260 Indoor Flexible Cast Iron Drainage Pipe (Flexible Interface) Nominal Diameter (within mm) 100 10m 0

Rubber ring socket connection method: BAI's cast iron pipe sleeve is installed with DU quota outdoor pipe, and the socket is cast iron DAO water supply pipe (rubber ring interface) with the corresponding subheading. Back or municipal quota answer (municipal engineering) socket cast iron pipe installation (rubber ring interface) subheading.

What is the difference between the two quotas in the quota about cast iron pipes 1 "flexible seismic cast iron drainage pipe (flexible interface)" 2 "flexible connection mechanism centrifugal cast iron drainage pipe (stainless steel clamp connection)" How to correctly arbitrage.

As explained by Taishan Beidou, the flexible interface is suitable for A-type cast iron pipes, which is consistent with this subheading, and the auxiliary materials contain flange gland bolts and other contents. Stainless steel clamp connection is suitable for W-shaped cast iron pipes, just use stainless steel clamp lined with rubber pads, placed on the outside of the interface and fastened with the clamp's own bolts.

1. Telescopic rubber soft joints, the set of flange sleeve expander installation quota.

2. Rubber joints, also known as flexible rubber joints, rubber soft joints, rubber flexible joints, soft joints, shock absorbers, pipeline shock absorbers, shock absorbers, shock absorbers, etc., are pipe joints with high elasticity, high air tightness, medium resistance and weather resistance. The product makes use of the elasticity, high air tightness, medium resistance, weather resistance and radiation resistance of rubber, and is made of polyester cord fabric with high strength and strong cold and heat stability after being composed with it diagonally, and then vulcanized by high-pressure and high-temperature molds.

3. The expansion joint is also called expansion joint, expansion joint, compensator, and expansion joint. According to the material, the retractor is divided into: steel retractor, rubber retractor, and stainless steel retractor.

The expander can be axially expanded within a certain range, and can also overcome the deviation caused by the different axial directions of the pipeline docking within a certain angle, which can greatly facilitate the installation and disassembly of the valve pipeline, and can be freely expanded and contracted in the allowable expansion amount of the pipeline, and once the maximum expansion and contraction amount is crossed, it will play a limit to ensure the safe operation of the pipeline. It is mainly to ensure the safe operation of the pipeline, and has the following functions: to compensate for the axial, transverse and angular thermal deformation of the absorption pipeline; Absorb equipment vibration and reduce the impact of equipment vibration on pipelines; Absorb the deformation of the pipeline by subsidence.

The application of the bai of municipal engineering quotas, first of all, you must understand.

The construction principle of the quota item set by Du is then pressed.

DAO according to the construction of the version of the situation combined with the pricing regulation.

The quantity calculation rules in the authority are applied.

The order of preparing the budget by the unit price method: 1. List the sub-projects; 2. Calculate the quantity of the list; 3. Set of budget fixed unit price; 4. Quantity analysis; 5. Summary unit price of various expenses; 6. Review and sort.

It is necessary to pay attention to the difference between the calculation rules of the list quantity and the valuation quantity, and the adjustment of the conversion content of the quota.

Practice more and gain experience through learning.

The purpose of the municipal engineering calculation is to carry out the quota.

Whether the municipal engineering takeoff is calculated by ** or by other means, this is just the difference in method.

In addition to Glodon, there are many software for arbitrage quotas, and you can choose by yourself. Thank you!

You can see if the municipal quota 06 price 6-468 to 6-474 is suitable for you.
