All backfilled areas must be drained of accumulated water and cleared of debris such as ice cubes. The thickness of each layer of filling should be smaller than that in summer, generally not exceeding 2cm. It should be compacted with a hammer or roller, and a small amount should be excavated into the lower part of the guide ditch, but not exceeding 2/3 of the thickness of the frozen soil layer. Excavation protection. After excavation of the foundation pit, timely insulation measures should be taken to prevent the formation of frozen soil. After passing the inspection, proceed to the next process in a timely manner. In the welding construction of steel reinforcement engineering, when steel reinforcement butt welding or arc welding is carried out under the condition of ambient temperature below -5 ℃, it is negative temperature welding of steel reinforcement. Welders engaged in steel reinforcement welding production must hold a certificate of qualification for the steel reinforcement welding examination.
Performance characteristics of polytetrafluoroethylene board:

1. Strong acid resistance Strong alkali, almost resistant to all chemical media, except for molten alkali metals and elemental fluorine.

2. Outstanding insulation performance, good aging resistance and weather resistance.

3. Low friction coefficient, PTFE board staircase embedded board, not easy to bond, easy to install and disassemble

4. The product is clean and can be used in sealed areas that are not allowed to be contaminated, such as food

Thirdly, the marble countertop material is highly durable, with outstanding scratch resistance, wear resistance, high temperature resistance, and maintenance free. Good rigidity, high hardness, strong wear resistance, and minimal temperature deformation. There will be no scratches, not hindered by constant temperature conditions, and its original physical properties can be maintained at room temperature. Fourthly, it does not deform, has high hardness, and strong wear resistance. The rock has undergone natural aging, with a uniform organizational structure, extremely low coefficient of linear expansion, disappearance of internal stress, and no deformation. Not afraid of acid and alkali erosion, will not rust, does not need to be oiled, is not easy to stick to dust, easy to maintain, and has a long service life. Five is Physically stable, meticulously organized, with grain shedding upon impact, no burrs on the surface, and no impact on its flatness accuracy. The material is stable, ensuring no deformation, low coefficient of linear expansion, high mechanical accuracy, rust prevention, demagnetization, and insulation.

5. High mechanical strength, good turning performance, and easy processing into different sealing products.

6. The coefficient of linear expansion is low, and it is prone to creep or stress relaxation during cold flow and high temperature under compression, making it unsuitable for use in high-temperature and high-pressure areas.

PTFE board is mainly used in engineering stairs as a hard PTFE stair support, which is relatively widely used in current staircase applications. Because the stairwell does not participate in the overall seismic calculation of the structure, sliding supports need to be designed according to traffic restrictions. The practical specifications of PTFE boards for stairs must meet the design requirements and construction specifications.

This installation process is generally used for the exterior walls of large buildings or for large-scale wall decorations in home decor. Traditional wet methods are commonly used in home decoration, which requires customers to choose high-quality stones for installation and use before making a choice to prevent stone infiltration in the future. In order to maintain the natural color of the stone during use, it is necessary to maintain and care for the stone used. Generally, stone maintenance agents are often used to maintain the surface of the stone, thereby reducing the yellowing and alkali returning phenomena and water marks that are not easy to dry after use. This helps to maintain the natural color of the natural stone and prolong its service life.
