Description :

　　1. Classification of plastic waterstop tape applied outside the post pouring strip:

　　The plastic waterstop attached to the post pouring strip can be divided into two types in terms of structural form: EB type waterstop and EP type waterstop. It is worth noting that due to the placement of plastic waterstops on the upstream surface of the concrete, it is often required to weld and seal with the waterproof board during the construction process. Therefore, in this case, it is necessary to choose a plastic waterstop with the same material as the waterproof board (such as EVA waterproof board using EVA plastic waterstop). In addition, after using the plastic waterstop on the outside of the post pouring belt, attention should be paid to the protection of the plastic waterstop when backfilling on the outside of the concrete wall panel.

　　2. Selection standard for plastic waterstop tape applied outside the post pouring strip

　　Design and selection standards for plastic waterstop tape outside the pouring belt: In the process of engineering design and construction selection, the width and thickness of the plastic waterstop tape outside the pouring belt should be determined according to the following conditions: when the water pressure is less than 4m and the horizontal slow and straight deformation does not exceed 10mm, the width of the plastic waterstop tape outside the pouring belt should not be less than 200mm and the thickness should not be less than 5mm; when the water pressure is 4-8m and the horizontal slow and straight deformation does not exceed 30mm, the width of the plastic waterstop tape outside the pouring belt should not be less than 300mm and the thickness should not be less than 6mm. In the planning of large-scale engineering buildings, there are certain elastic requirements between civil engineering and water and soil structures. Therefore, the use and installation of plastic waterstop tape outside the pouring belt also have waterproof and seismic requirements. Applying waterstops is a method to solve various problems encountered in the above projects.

　　3. Installation inspection of plastic waterstop tape applied outside the pouring belt:

　　A、 The horizontal position for installing plastic waterstops outside the pouring strip should be measured with a steel tape measure from the inner mold to the waterstop. The deviation from the design position should not exceed 5cm.

　　B、 The longitudinal position for installing plastic waterstops outside the post pouring strip is usually symmetrical on both sides with the construction joint or expansion joint as the middle. The waterstop should be checked with a steel tape measure, and the deviation from the middle should not exceed 3cm.

　　C、 Use an angle ruler to check if the plastic waterstop attached to the outer surface of the pouring strip is orthogonal to the lining end template, otherwise it will reduce the length of the waterstop.

　　4. Transportation of plastic waterstop tape attached outside the post pouring belt:

　　The plastic waterstop tape applied outside the post pouring strip is mainly used in the construction joints of culverts. Plastic waterstops with different quality are suitable for different construction positions. Plastic waterstops should not be applied outside the pouring strip after culvert construction joints, and should not be exposed to sunlight for a long time to prevent rain and contact with highly polluting chemicals; Prevent mechanical and steel damage to the waterstop during transportation and construction; During the construction process, the waterstop should be reliably fixed to avoid displacement during concrete pouring and ensure the correct position of the waterstop in the concrete.

　　Plastic waterstops are applied to the outer surface of the post pouring belt according to the requirements of specific water conservancy projects. Different specifications of waterstops can be customized. When users order waterstops, the product length should be calculated according to the engineering structure and design drawings. For irregular structures, drawings should be provided. It is recommended to connect the waterstops as a whole in the factory. If on-site connection is required, electric heating plate vulcanization bonding, cold bonding, or welding (plastic waterstops) methods can be used.
