Lanzhou Water Swelling Rubber Waterstop Factory Trends
Construction method and construction specification of water-swelling water-stop strip
Due to design, construction technology and construction organization reasons, the structure cannot be continuously poured as a whole, and the intermittent time exceeds the allowable duration of concrete transportation and pouring. â‘¡When leveling, if there are beams within 2 cm on both sides of the beam end seam The concrete joint surface where the slab protrudes and is poured successively is called a construction joint.
1 Types and causes of problems in the construction process of construction jointsFrom some projects that have been contacted in the past, the construction quality problems caused by construction joints mainly fall into two categories: one is the improper location of the construction joint; the other is the construction time The handling of construction joints is improper, and Yu Xiang, the board of directors of CDC (), told reporters
1.1 Improper location of construction joints
The construction joints were not set in places with low stress in accordance with the requirements of the specification when leaving the construction joints. Places that are difficult to achieve, such as when installing close to the top of the foundation beam and using steel waterstops, are difficult to place due to conflicts with the beam stirrup position. Lanzhou Water-swellable Rubber Waterstop Factory Trends Hengshui Shenghong Rubber Products Co., Ltd. welcomes you to Lanzhou Water-swellable Rubber Waterstop Factory Trends Introduction to the construction method and construction specifications of the water-swellable rubber waterstop
1. In the installation of bw putty type water-stop pair, there is a reserved pasting method, and the water-stop strip placement slot should be reserved in the first pouring concrete (the wooden strip can be reserved in the template)
2. After removing the first poured concrete formwork, clean the surface to make the joint surface water-free, clean and free of debris. Construction method and construction specification of water-swelling water-stop strip
3. Insert bw putty type water stop into the reserved groove. If no groove is reserved, the vertical seam can be pasted with an adhesive for the full length, or cement nails and wooden strips can be used to fix the waterstop; the unit commodity energy consumption quota of tires can be directly pasted on the concrete surface for the horizontal seam.
4. The concrete should be poured as soon as possible after bw putty type water stop paste. Construction method and construction specification of water-swelling water-stop strip
5. During the installation and pasting process, the bw putty-type water stop strip should be prevented from being polluted and swelled by the action of water, so as to avoid sound effects.

Water-cooled capacitor is supercapacitor is a capacitor with a capacity of thousands of farads.According to the principle of capacitor, capacitance depends on the distance between the electrode and electrode surface area, in order to get such a large capacitance, as far as possible to narrow the distance between the super capacitor electrode, electrode surface area increased, therefore, through the theory of electric double layer and porous activated carbon electrode.
