After the exterior wall is poured, it is strictly forbidden to open the hole, all the embedded parts and buried pipes at the hole should be reserved, and the reinforcement of the hole side is detailed in the construction drawing. Reserved reinforcement in walls and columns.
To do lightning protection grounding leads, they should be welded into a path. Its location, quantity and practice are detailed in the installation construction drawings, and qualified welders should be selected for welding work.
OK, the structural reinforcement shall not be damaged, the pre-embedding of hydropower installation, civil engineering must be cooperated, and the burial and leakage shall not be staggered.
Beams & Slabs. The longitudinally stressed reinforcement appears double.

Advantage 1: High drainage efficiency and long service life.
The first-class resin drainage ditch has a strong drainage capacity, and the efficiency of continuous water interception is very high, the ability to resist aging and the ability to resist corrosion in the process of use is strong, so the service life of the resin drainage ditch is ensured, and in some high-level places where the pavement landscape requirements are relatively high, this kind of drainage ditch can be adaptable to the place, can be used with so the ground decoration materials, and the load capacity is extremely strong, and has good load-bearing performance.
Advantage 2: High stability and strong corrosion resistance.
**The raw materials of the cost-effective resin drainage ditch are basically environmentally friendly and energy-saving new building materials, and the resin is used instead of traditional cement, and it is bonded together with other aggregates, and its strength and chemical stability are significantly leaped compared with ordinary silicone salt concrete.
Advantage 3: easy to transport and install, beautiful appearance.
Professional resin gutters are stronger than ordinary gutters, so they are lighter in weight and easier to install. The appearance of this kind of product is beautiful and generous, but also more in line with the practical and simple requirements of modern designers, in the overall design of the city not only does not destroy the aesthetics, but adds brilliance.
The above are a few important advantages of resin gutters, and it is precisely because of these advantages that resin gutters can occupy such an important position in the modern market and play such a satisfactory effect in urban life. In the future development process, it is believed that the resin drainage ditch can continue to innovate and continue to contribute to today's rapid urban life.
-
The upfront investment in resin gutters is about half the cost of traditional gutters, but the overall consideration is that resin gutters save money.
The resin drainage ditch has a long service time and a long maintenance cycle, so it does not need to be cleaned frequently, and the traditional use time is short, and it is time-consuming and laborious to repair frequently.
-
Compared with traditional ditches, resin ditches have the following advantages.
1. The material is environmentally friendly, the inner wall is smooth and does not hang scale, it can be cleaned by itself and is not easy to block, saving the maintenance cost in the later stage;
2. In terms of performance, it can continuously collect water and have strong drainage capacity;
3. The construction is simple and fast, saving manpower and material resources;
4. Beautiful appearance, all kinds of cover plates for free matching;
5. It not only satisfies the displacement, but also solves the problem of limited soil covering.
The resin ditch is the second generation of finished drainage ditch, and now the project project generally uses the third generation of finished drainage ditch recommended by the state - HDPE finished drainage ditch.
-
1. The material is resin concrete, with high load-bearing capacity, high hardness, strong anti-aging, anti-freezing and anti-corrosion, and low permeability;
2. According to different construction environment and bearing requirements, different cover plates can be used to meet the needs of various construction sites;
3. The unique U-shaped design and smooth inner wall have high drainage efficiency and no water accumulation;
4. The construction and installation are simple and fast, saving manpower, material and financial resources;
5. Simple and unified linear appearance, not only drainage, but also add color to the surrounding environment.
-
High strength, both compressive strength and bending strength are 1 times higher than concrete;
It does not absorb water, so that it will not freeze and thaw and crack when the temperature is relatively large;
The surface of the inner wall is smooth, the drainage effect is good, and it is not easy to hang garbage and dirt;
The construction is simple, and the installation is carried out after the on-site pay-off, mainly for sealant connection, and finally for grouting and curing.

Resin concrete linear drainage system includes: stainless steel middle joint linear drainage ditch, stainless steel side joint linear drainage ditch, stainless steel double joint, triple joint linear drainage ditch, U-shaped finished resin concrete linear drainage ditch, galvanized steel linear drainage ditch cover, ductile iron linear drainage ditch cover, etc. The main material of resin concrete has the advantages of high strength and light weight, polyester resin concrete can absorb external impact force, and its compressive and bending strength is 3 times that of traditional concrete, but the weight of components of the same compressive level is significantly lower than that of ordinary concrete.
Polyester resin concrete is easy to bond and has the characteristics of high water resistance, easy to process, drill and cut on the construction site, and will not cause changes in its performance, and it has the advantages of easy construction and easy installation, which is conducive to the shortening and mastery of the construction period.
It is best to reserve the ditch first, dig the required size, generally use the finished drainage ditch now, and then put the ditch body, cover plate, and then pave.

Multicollinearity refers to the correlation between independent variables, that is, an independent variable can be expressed by the linear expression of one or several other independent variables. If multicollinearity exists, the matrix is irreversible when calculating the partial regression coefficients of the independent variables, resulting in an infinite number of solutions or no solutions. >>>More
