Common problems and construction priorities of hidden projects

>>> Interpretation of hidden construction site

Home decoration is an engineering project consisting of dozens or hundreds of process constructions of different sizes. Due to the construction of follow-up procedures, the former construction link was hidden and a “hidden project” was formed.

The concealed project will not be exposed to the outside after the completion of the construction. Once a quality problem occurs, it will often affect the quality of the surface decoration layer or other related parts. For example, when laying the wire, if the PVC pipe is not properly worn, the electricity test is not conducted before covering the surface layer after completion, and the wire tube is concealed if there is no correct detection and acceptance according to the electrical operation rules. Power failures can only be found. It is conceivable that the damage to the surface decoration can be done in this way. Therefore, there is no good grassroots level, and there can never be a good surface. The importance of hidden projects is self-evident.

Typical covert engineering problems are:

After the floor joists hit the concrete joists by the cement dock, the cement mortar was separated from the ground joists. The cement residue was left on the surface of the ground joists without clearing and the nail floor was laid, which resulted in separation between the floor and the joists. Layers, the floor will sound when walking: cross cabinets, cabinets, wooden doors and other cross-section when the dice, some workers easy to use nails to connect, do not have dice;

After the gas pipelines are connected in place, they do not pay attention to twisting in the opposite direction, resulting in gas leaks; improper use of galvanized pipes for the upper water pipelines;

The bathtub water outlet is not connected with the head of the pit tube, and the gutter at the bottom of the bath is used for drainage; the bottom of the toilet bowl is sealed with cement mortar, and if the toilet is overhauled, it is scrapped; the toilet installation is positioned because the pit distance is not enough, causing any difficulty in running the water. Large; leakage of upper and lower water joints; blindly expanding the bathroom, water is poured from the slab and the pre-plate;

Wood moisture content is too high; wood components are not boring; doors and windows are not firmly connected to walls; wood components are degummed; mirror surfaces in wet areas are not waterproofed; wires are discharged directly into walls without PVC pipe; wire connections are not standardized; blind Knocking makes the head of the beam or brick arches off the resting point, does not check the reinforcement, externally encapsulates the matter, and so on.

Owners should focus on these hidden projects. In addition to the decoration must choose a large-scale decoration company with a reputation, but also in the supervision of their own longer.

Pipeline laying is the focus

In home decoration, some hidden projects are indispensable, and the laying of pipelines is the focus of hidden projects.

Pipeline laid-out projects include: line-power lines, television lines, television signal transmission lines, intercom systems, security anti-theft system wires, audio surround system wires, etc.; pipelines - water pipes, sewage pipes, heating pipes, gas pipes, Water heater connection pipe and so on. In the specialized construction, strict requirements are placed on the selection of materials and construction steps. Only by mastering these specific construction requirements can we effectively supervise the quality of hidden projects.

Pipeline class. The transformation of the upper water pipe and the heating pipe should be designed to be the most multiplication pipe route, and the elbow should be reduced as much as possible. Water pipe joints are made of raw material tape as the sealing material, and heating pipe joints are used as "linen wipes lead oil" to prevent the heat from affecting the sealing effect. The seals installed on the heating door should be laid flat, placed properly, and forcefully applied when tightening. Otherwise, the force will be used to fract seal the assembly, and if the force is light, the seal is not strict. Can cause leakage, seepage. Sewer pipes: The old building is made of cast iron pipe fittings. Some of the new buildings are made of rigid engineering plastic pipes, and they are fixed in position and layout in the structural engineering. They should not be easily moved. In principle, home improvement projects should not be changed. The sewage pipes are mainly anti-blocking, including the sewers and floor drains of kitchens and bathrooms, especially the cement and sand when the walls and paving slabs are removed, do not fall into the drains and floor drains. When the home improvement package includes heating and bag risers, the gates and gate valves shall all be left as maintenance ports, and they shall be prepared for future maintenance and overhaul. Gas pipe: Due to the gas pipe's moving transformation and the gas water heater's installation, it is easy to cause leakage of gas and natural gas, which is dangerous. Therefore, the gas company's professional construction team should be invited to construct and go through the approval process.

DBB Plug Valve

DBB Plug Valve called double block-and-bleed plug valves which is high-integrity, positive shut-off valves. DBB plug valve have advantages of easy maintenanceand repair. The valve size is from 2" to 24" with matching valve pressure from class 150 to class 900. DBB plug valve normally used in oil tank in airport with double sealing to protect oil pipeline from any risks, such as fire or leakage etc.
