Description

Technical Field

[0001] The present invention relates to the technical field of embedded pipeline installation construction, specifically a PPH waterproof casing positioning device and a positioning method. Background Technique

[0002] PPH, namely homopolypropylene, is a high-performance polymer material. It has the characteristics of high molecular weight and low melt flow rate, enabling it to perform excellently in various environments. Specifically, the PPH material has excellent chemical resistance and can resist the erosion of various chemical substances; at the same time, it also has good high-temperature resistance and can remain stable under high-temperature conditions; in addition, its creep resistance is also very excellent, meaning that it is not easy to deform under long-term stress. It is worth mentioning that in a low-temperature environment, the PPH material also exhibits excellent impact resistance and is not easy to break. In the field of environmental protection equipment, PPH pipes are one of the most common applications. Because they are non-toxic, odorless, corrosion-resistant, and easy to process, they are widely used for transporting various fluids, which is both environmentally friendly and safe.

[0003] However, in the installation process of the PPH material embedded casing body, the traditional welding method has some deficiencies. First of all, the fastening force of welding is often insufficient, which may cause the casing body to loosen or fall off during use; secondly, since the welding accuracy largely depends on the experience and technical level of the welding personnel, the welding quality is often unstable and prone to deviation. These problems often lead to the fact that the embedded casing body cannot meet the installation requirements of the equipment manufacturer, and there are often problems such as excessive deviation and insecure fixation during acceptance, which not only affects the progress of the project but also may pose potential safety hazards to subsequent use. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a PPH waterproof casing positioning device and a positioning method, which aim to solve the problems of unable to ensure the fastening force and welding accuracy when installing the PPH casing body mentioned in the above background technique.

[0005] The technical solution adopted by the present invention to solve its technical problems is: A PPH waterproof casing positioning device includes a casing body, and also includes a connector body. A water stop ring is arranged in the middle of the casing body. The connector body includes several connecting plates, which are circumferentially spaced around the center of the casing body, and one end of the connecting plate is connected to the water stop ring of the casing body, and the other end is fixed to the pool body steel bars.

[0006] Compared with the prior art, the beneficial effects of the present invention are: The device is provided with a connecting plate to fix the water stop ring of the casing body to the steel bars of the pool body, ensuring the installation accuracy and fastening force of the casing body, avoiding subsequent deviations of the casing body resulting in low installation accuracy and rework due to acceptance failure, effectively improving the installation accuracy of the casing body, reducing the frequency of rework, and saving time and cost.

[0007] Preferably, a further technical solution of the present invention is: Preferably, a positioning hole is provided at one end of each connecting plate connected to the water stop ring, and the connecting plate is connected to the pipeline body via a bolt assembly penetrating the positioning hole and the fixing hole on the water stop ring.

[0008] Preferably, 3-6 connecting plates are provided.

[0009] The present invention also discloses a PPH waterproof casing positioning method, the specific steps are as follows: S1. Determine the number of connecting plates according to the diameter of the pipeline, and then cut the flat steel; S2. According to the position of the fixing hole on the water stop ring, a positioning hole is drilled for each connecting plate; S3. Use bolt assemblies to connect the connection plate to the fixing holes on the water stop ring accordingly; S4. Place the casing body with the connecting plate installed to the designed position according to the construction design drawings, and adjust the position of the casing body. After the position is adjusted correctly, weld each connecting plate to the tank body steel bars around the casing body, and the installation is completed.

[0010] Compared with the prior art, the present invention adopting the above technical solution has the following outstanding features: The method uses a connecting plate to position and connect the casing body and the tank body steel bars, which solves the problems of positioning deviation and loose installation when the traditional waterproof casing is installed through the cross steel bars, improves the installation quality and installation accuracy of the casing body, and ensures the progress of the project construction.

[0011] The size of the connecting plate is 100mm*50mm and the thickness is 5-10mm.

[0012] The bolt specifications are selected according to the size of the water stop ring fixing hole of the PPH casing body. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] As Figures 1 to 5 shown, a positioning device for a PPH waterproof casing 1 is composed of a casing body 1 and a connector body. A water stop ring 2 is provided in the middle of the casing body 1, and a plurality of fixing holes 3 are circumferentially formed on the water stop ring 2 around its central axis.

[0017] The connector body is composed of a plurality of connecting plates 4. The connecting plates 4 are circumferentially and spaced apart around the central axis of the casing body 1. One end of each connecting plate 4 is connected to the water stop ring 2 of the casing body 1, and the other end is fixed to the pool body steel bars 5. Specifically, in this embodiment, 3 - 6 connecting plates 4 are provided. In this embodiment, 4 connecting plates 4 are provided. Each end of each connecting plate 4 connected to the water stop ring 2 is respectively provided with a positioning hole 6. The aperture of the positioning hole 6 is equal to the aperture of the fixing hole 3 on the water stop ring 2. The connecting plate 4 is connected to the pipeline body through a bolt assembly 7 passing through the positioning hole 6 and the fixing hole 3; the other end of the connecting plate 4 is fixedly welded to the pool body steel bars 5.

[0018] Based on the above positioning device, the specific construction steps are as follows: S1. Determine the number of connecting plates 4 according to the diameter of the pipeline. The larger the pipeline diameter, the more the number of connecting plates 4. In this embodiment, taking four connecting plates 4 as an example, the size of each connecting plate 4 is 100mm * 50mm, and the thickness is 5mm. Cut the flat steel according to the size of the connecting plate 4.

[0019] S2. Open the positioning holes 6 on each connecting plate 4 according to the positions of the fixing holes 3 on the water stop ring 2. The aperture of the positioning hole 6 is equal to the aperture of the fixing hole 3 on the water stop ring 2.

[0021] S4. Place the casing body 1 with the connecting plate 4 installed thereon at the designed position according to the construction design drawings, and adjust the position of the casing body 1. After the position adjustment is correct, weld and fix the ends of each connecting plate 4 away from the water stop ring 2 to the surrounding pool body steel bars 5 respectively, and the installation is completed.

[0022] In the present invention, the PPH casing body is connected to the pool body steel bars by means of connecting plates, which ensures the installation accuracy and fastening force, avoids situations such as low installation accuracy caused by subsequent deviations of the casing body and rework due to failed acceptance, effectively improves the installation accuracy of the casing body, reduces the frequency of rework, and saves time costs; the connecting plates and the PPH casing body are connected by bolts, which avoids damage to the casing body caused by welding and reduces the engineering material costs.
