Description

Technical Field

[0001] This invention relates to the field of construction technology for elbow-shaped flow channels in pumping stations, and in particular to a multi-structure irregular template positioning device for elbow-shaped flow channels in pumping stations. Background Technology

[0002] When installing elbow-type flow channel formwork in pump stations, wooden or steel formwork is typically used. Wooden formwork can only be used once, its shape cannot be adjusted, and it cannot be reused. The overall integrity of wooden formwork is poor, making it prone to problems such as formwork displacement, misalignment, and floating during concrete pouring. Furthermore, it is all for single use only, and dismantling is destructive, requiring a large amount of material for internal supports and taking a long time, leaving it with no value for reuse after dismantling. Steel formwork, after being processed and formed, lacks sufficient precision in its shape, requires a large amount of steel for processing, and has high production costs. Moreover, since elbow-type flow channels are mostly transitional sections, steel formwork is for single use only and cannot be reused. After dismantling, the formwork becomes a pile of scrap metal, further increasing production costs. Summary of the Invention

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0022] This invention provides a positioning device for a multi-structure irregular template in an elbow-type flow channel of a pumping station. (See attached image) Figure 1-4The system includes: a fixed telescopic device 100, a positioning device 200, a template 300, and a sealing device 400. Multiple fixed telescopic devices 100 of different sizes are installed on the outside of the positioning device 200 to form a basic shape. The template 300 is installed on the fixed telescopic device 100 to complete the overall structure. The sealing device 400 seals the gaps between the templates 300. The positioning device 200 includes a keel 210 with positioning scales 211 for positioning according to the flow channel centerline. The template 300 consists of multiple template blocks 310 with concave surfaces and drilled holes.

[0023] The fixed telescopic device 100 supports and finely adjusts the position of the template 300; the positioning device 200 provides a reference positioning based on the graduated keel 210 with the center line of the flow channel; the sealing device 400 ensures a seal between the templates 300; the template 300 consists of template blocks 310 with concave surfaces and drilled holes, which are fitted and fixed with the positioner. All components are detachably connected, facilitating assembly, adjustment, and recycling.

[0024] The fixed telescopic device 100 is detachably connected to the positioning device 200 and the sealing device 400. The template 300 is assembled from multiple template blocks 310 with concave surfaces and drilled holes, and is detachably fixed to the positioning device 200 and the sealing device 400. Each component can be quickly assembled and disassembled to adapt to different flow channel sizes, reducing customization costs and enabling modular design. The fixed telescopic device 100 and the positioning device 200 work together to ensure the accuracy of the flow channel surface (error ≤3mm), achieving precise positioning. The sealing device 400 fits into the template 300 to prevent concrete leakage, improve molding quality, and provide a leak-proof seal.

[0025] In one embodiment, see Figure 7 The fixed telescopic device 100 includes a positioning ring 110, a hydraulic telescopic rod 120, an outer steel plate device 130, and a template support device 140. Multiple hydraulic telescopic rods 120 are evenly distributed around the outer ring 110 on the positioning ring 110. The outer steel plate device 130 is installed on the hydraulic telescopic rod 120, and multiple template support devices 140 are installed on the outside of the outer steel plate device 130.

[0026] For example, four hydraulic telescopic rods 120 are symmetrically arranged around the outer ring of the positioning ring 110 and are detachably connected to the positioning ring 110.

[0027] The 120 hydraulic telescopic rods are symmetrically distributed to ensure balanced support for the 300-meter template and guarantee concentricity. Each 120 hydraulic telescopic rod can be adjusted independently to adapt to local curvature changes and allow for flexible adjustments.

[0028] In one embodiment, see Figure 5 The positioning ring 110 is provided with a first fixing bolt 111, which fixes the positioning ring 110 to the positioning device 200.

[0029] For example, four first fixing bolts 111 are evenly distributed on the outer ring of the positioning ring 110. The four first fixing bolts 111 are evenly stressed, avoiding misalignment and ensuring concentricity.

[0030] In one embodiment, see Figure 6 The outer steel plate device 130 is provided with reserved holes 131, which are distributed according to the cross-sectional shape of the flow channel and are used to fix the hydraulic telescopic rod 120 and the template support device 140.

[0031] The outer steel plate device 130 has slight deformation capabilities and adjustable thickness. This deformation capacity compensates for construction errors, and the thickness adjustment allows it to match the positional requirements of different templates 300, enhancing adaptability. Pre-drilled holes 131 reduce on-site drilling time, increasing efficiency by over 30% and enabling rapid installation.

[0032] In one embodiment, see Figure 7-14 The template support device 140 includes a simple locator 150 and a non-standard locator 160, which are selected for installation according to the degree of change in the cross-sectional shape of the flow channel; the non-standard locator 160 has auxiliary locators 174 around its main locator 170, and the simple locator 150 has an auxiliary locator 174 on each side of its main locator 170.

[0033] The simple locator 150 is used to reduce costs for straight sections, while the irregularly shaped locator 160 provides multi-directional fixation for curved sections, preventing template 300 from shifting and ensuring precise fit. The four-sided auxiliary locator 174 provides 360° positioning, ensuring stability on complex curved surfaces and achieving multi-angle support.

[0034] In one embodiment, the main locator 170 includes a main rod 171, a locating element 172, and a second fixing bolt 173. The locating element 172 is mounted on one end of the main rod 171, and the second fixing bolt 173 is used to mount the other end of the main rod 171 onto the outer steel plate device 130. The auxiliary locator 174 includes a rotating shaft 181, a rotating rod 182, and a locating element 172. The locating element 172 is mounted on one end of the rotating rod 182, and the other end of the rotating rod 182 is mounted on the main rod 171 via the rotating shaft 181.

[0035] The rotating rod 182 can be adjusted in real time to accommodate local tilting of the template 300 (adjustment range ±15°), achieving dynamic adjustment. The rotating shaft 181 is welded to the main rod 171 to ensure support strength, resist lateral pressure from concrete, and provide rigid fixation.

[0036] In one embodiment, the positioning element 172 includes a connector 191, a connecting post 192, and a positioning head 193.

[0037] In one embodiment, a drilled hole is provided at the center of the concave surface of the template block 310, which is fitted and fixed with the positioning head 193, and the concave surface contour matches the positioning head 193.

[0038] The concave surface of the template block 310 matches the positioning head 193, which reduces the gap between the template block 310 and the positioning head 193 at the installation point. The drilled hole is inserted and fixed to the positioning head 193, which improves the assembly and disassembly efficiency by 50% and achieves quick locking.

[0039] In one embodiment, see Figure 15 The keel 210 is made according to the center line of the flow channel, and the surface is marked with positioning scale 211. The inside of the curved section is equipped with an irregular positioning device 160, and the straight section uses a simple positioning device 150.

[0040] The graduated markings guide installation, avoiding errors from manual measurement and enabling visualized construction. The irregular / simple positioning device can be used in 150-point areas, reducing costs while maintaining accuracy, with optimized zoning.

[0041] In one embodiment, see Figure 16 The sealing device 400 is an I-shaped sealing strip made of elastic rubber with an I-shaped cross section, which is embedded between the template blocks 310.

[0042] The I-beam structure, after compression, fills the joints, improving grout leakage prevention by 90% and providing a double seal. The rubber is corrosion-resistant and has a service life of over 10 years.

[0043] In one embodiment, the extension stroke of the hydraulic telescopic rod 120 is digitally controlled by an external hydraulic system.

[0044] Digitally controlled telescopic movement (accuracy ±0.5mm), suitable for high-precision flow channels. Reduces manual climbing and adjustment, improving safety.

[0045] This invention achieves dynamic adjustment of the shape of the template 300 through the hydraulic telescopic rod 120 and the positioner, which solves the problem that traditional wooden molds for elbow-shaped flow channels in pumping stations are prone to deviations in the shape, appearance and size of the concrete structure, reducing the service life of the elbow-shaped flow channel. In this way, the shape of the flow channel cross-section can be accurately obtained through the positioner, thus extending the service life of the concrete structure.

[0046] This invention solves the problem that when sealing the template 300 of the traditional elbow-type flow channel wooden or steel template in pumping stations, the template 300 is often not properly sealed, leading to concrete leakage and causing the pouring work to fail. It achieves the effect of completely sealing the template 300, preventing concrete from flowing out, and providing good sealing performance.

[0047] This invention combines template block 310 with I-beam sealing strip, which facilitates disassembly and reuse. It solves the problem that traditional elbow-type flow channel wooden and steel molds are difficult to disassemble after the flow channel is poured, and the template 300 cannot be reused. Thus, the template 300 is easy to install and disassemble and can be reused.

[0048] This invention ensures the geometric accuracy of the flow channel transition section by using the 210 scale of the keel and the positioning, thus ensuring the forming effect and quality of the irregular flow channel.

[0049] This invention provides a construction method for a positioning device 200 for a multi-structure irregular template 300 in a pump station elbow-type flow channel, comprising the following steps: Step 1: Customize template 300, keel 210 and outer steel plate device 130 according to the flow channel drawing, install keel 210 and calibrate the scale.

[0050] A template 300 is customized according to the elbow-shaped flow channel drawing, and a keel 210 is made according to the center line formed by connecting the center points of each section on the elbow-shaped flow channel drawing. Scales are marked on the surface of the keel 210 to provide positioning function for the subsequent installation position of the template 300. Steel plates are customized according to the shape of each template 300 and its corresponding elbow-shaped flow channel section to make them correspond to the shape of the flow channel template 300. Drill holes are made on them to facilitate the installation of the positioner on the steel plate and the fixing of the steel plate on the hydraulic telescopic rod 120. After the hydraulic telescopic rod 120 is adjusted, the outer steel plate is fixed.

[0051] When installing the template 300, it is necessary to install it according to the position of the corresponding section of the template 300 on the keel 210, and fix it with the first fixing bolt 111 on the positioning ring 110. When the keel 210 is straight, the template 300 can be tightly attached to the positioning ring 110, so that the template 300 section is smoother and has better sealing.

[0052] Step 2: Select a simple locator 150 or a non-standard locator 160 and install it on the outer steel plate device 130. Adjust the angle of the locating head 193 by rotating the auxiliary locator 174.

[0053] Install a simple positioner 150 or a non-standard positioner 160 according to the degree of change of the corresponding elbow-shaped flow channel cross section. The positioner fixes the template 300 to the device through the positioning head 193. If the distance between the template 300 and the device is large at a certain point, the steel plate of the template 300 can be thickened to a certain extent.

[0054] Adjust the position of the locator and the position of the locating head 193 of each template 300 according to its corresponding cross-sectional shape. At the bend of the keel 210, position and install the device with the irregular locator 160 according to the position of the flow channel drawing, so that the auxiliary locator 174 of the irregular locator 160 on the inner side of the keel 210 can be fixed to the corresponding template block 310.

[0055] Step 3: Fix the template block 310 with the positioning head 193 and embed the I-shaped sealing strip between the blocks.

[0056] When each locator is fixed to its corresponding template block 310, an I-beam sealing strip is installed between each template block 310 to seal the entire outer side of the template 300. Concrete pouring can then proceed. The device is constructed of steel, has a long service life, is easy to disassemble, and can be customized to different specifications to suit various users.

[0057] Step 4: After positioning is completed, pour concrete and then reverse the operation to recover the components during disassembly.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
