[0017] A prefabricated water channel implementation method for a component factory, comprising the following steps:

[0018] S1: Preparation before construction

[0019] (1) Foundation preparation

[0020] Ensure that the foundation of the construction area is flat and solid to support the weight of the water channel structure and steel formwork.

[0021] According to the design drawings, determine the center line, width, depth and shape of the water channel.

[0022] (2) Material preparation

[0023] Select a reliable prefabricated water channel steel formwork to ensure its accurate size, smooth surface and no damage.

[0024] Prepare an appropriate amount of concrete materials, including cement, sand, gravel, etc., and mix them according to the design requirements.

[0025] (3) Equipment preparation

[0026] Prepare the necessary construction equipment, such as cranes, vibrators, levels, iron nails, etc.

[0027] Ensure that all equipment is in good working condition and meets the safety operation requirements.

[0028] S2: Template installation

[0029] (1) Template positioning

[0030] According to the design drawings and the actual situation on site, determine the installation position and height of the steel formwork.

[0031] Use a level and measuring tools to make accurate measurements to ensure that the position of the template is accurate and the level meets the requirements.

[0032] (2) Template installation

[0033] Install the steel formwork in the order and position required by the design, that is, first place the bottom shell formwork horizontally on the ground, then take out the U-shaped inner formwork, align the bottom fixing slot with the fixing block for plugging and fixing, and use fastening bolts to fix the U-shaped inner formwork. After completion, lift the rectangular formwork on both sides, so that the rectangular formwork and the bottom shell formwork are perpendicular to each other, first insert the first side formwork welded with the T-shaped plug-in block into the C-shaped slot, after completion, push the second side formwork between the two rectangular formworks on the other side of the U-shaped inner formwork, and clamp the dovetail block into the dovetail slot, clamp the connecting plate into the F-shaped support block, and use the fixing pin to fix the connecting plate, thereby fixing the second side formwork.

[0034] After installation, use nails or other fixing tools to firmly fix the formwork to the road surface or the preset supporting structure.

[0035] Make sure the joints between the formwork are tight and seamless to prevent concrete leakage.

[0036] S3: Concrete pouring

[0037] (1) Concrete mixing

[0038] Pour the prepared concrete materials into the mixer and mix them according to the ratio required by the design.

[0039] During the mixing process, ensure that the concrete is uniform and free of lumps.

[0040] (2) Concrete transportation

[0041] Use transport vehicles to deliver the mixed concrete to the construction site.

[0042] During transportation, it is necessary to ensure that the concrete does not undergo segregation or stratification.

[0043] (3) Concrete pouring

[0044] Pour the concrete evenly into the installed steel formwork.

[0045] During the pouring process, the pouring speed must be controlled to prevent formwork deformation or concrete accumulation.

[0046] Use a vibrator to vibrate the concrete to remove bubbles and increase density. When the molding temperature is too low, affecting the molding effect, you only need to pour external hot water into the water inlet pipe, so that the hot water is stored inside the insulation shell, which can increase the internal temperature of the formwork, thereby forming a constant temperature curing environment, shortening the concrete growth time, and speeding up the formwork turnover.

[0047] S4: Formwork removal and maintenance

[0048] (1) Template removal

[0049] The formwork can only be removed after the concrete reaches the design strength.

[0050] When removing the formwork, follow the principle of top first, bottom later, outside first, inside later to avoid damaging the concrete components.

[0051] (2) Maintenance

[0052] The poured concrete components are maintained to ensure that they reach the design strength within the specified time.

[0053] During the curing process, the concrete surface must be kept moist to prevent it from drying out and cracking.

[0054] S5: Quality Inspection and Acceptance

[0055] (1) Quality inspection

[0056] During the construction process, the quality of the concrete, the installation position of the formwork, the levelness, etc. must be checked regularly.

[0057] Problems discovered should be rectified promptly to ensure that construction quality meets design requirements.

[0058] (2) Acceptance

[0059] After the construction is completed, relevant personnel will be organized to conduct acceptance inspection.

[0060] The acceptance content includes whether the size, shape, strength, etc. of the concrete components meet the design requirements.

[0061] Only after passing the acceptance test can the next step of construction or commissioning be carried out.

[0062] Compared with the prior art, the present invention provides a prefabricated canal steel formwork device for a component factory and its implementation method, which has the following beneficial effects:

[0063] 1. The canal steel formwork device of this design has a simple overall structure and can be disassembled and processed separately, so that when some components are damaged, they can be directly replaced, or when the formwork is severely worn, it can also be replaced in time, thereby reducing maintenance costs and improving the flexibility of the formwork device.

[0064] 2. The canal steel formwork device of this design is capable of adjusting the internal space of the canal mold by setting adjustable wing plates with adjustable spacing on both sides of the rectangular formwork. The formwork device can be adapted to the preparation of different types of canals, thereby effectively reducing the repeated investment and utilization of the mold, improving the versatility of the mold, and meeting diverse engineering needs.

[0065] 3. The channel steel formwork device of this design sets an insulation interlayer inside the formwork and an insulation shell on the outer wall of the rectangular formwork. When the weather temperature during molding is too low to affect molding, it is only necessary to pour external hot water into the water inlet pipe, so that the hot water is stored inside the insulation shell, which can increase the temperature inside the formwork, thereby forming a constant temperature curing environment, shortening the concrete growth time, and accelerating the formwork turnover.

[0066] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

10. A method for prefabricating a water channel in a component factory, using the steel formwork device for prefabricating a water channel in a component factory according to claim 1, characterized in that: The following steps are involved: S1: Preparation before construction (1) Basic preparation Ensure the foundation of the construction area is flat and solid to support the weight of the channel structure and steel formwork. According to the design drawings, determine the parameters of the channel such as center line, width, depth and shape. (2) Material preparation Choose prefabricated water channel steel formwork of reliable quality to ensure its accurate size, smooth surface and no damage. Prepare appropriate amounts of concrete materials, including cement, sand, gravel, etc., and mix them according to the ratio required by the design. (3) Equipment preparation Prepare necessary construction equipment, such as cranes, vibrators, levels, nails, etc. Ensure all equipment is in good working condition and meets safe operating requirements. S2: Template Installation (1) Template positioning Determine the installation position and height of the steel formwork based on the design drawings and actual on-site conditions. Use a level and measuring tools to take precise measurements to ensure the template is positioned correctly and level as required. (2) Template installation The steel template is installed in the order and position required by the design, that is, the bottom shell template (1) is first placed horizontally on the ground, and then the U-shaped inner template (5) is taken out, and the bottom fixed slot (4) is aligned with the fixed block (3) for plugging and fixing, and the U-shaped inner template (5) is fixed with the fastening bolt (6). After completion, the rectangular templates (9) on both sides are lifted up, and the rectangular templates (9) and the bottom shell template (1) are in a mutually perpendicular state. First, the first side template (22) welded with the T-shaped plug (21) is inserted into the C-shaped slot (20). After completion, the second side template (26) is pushed between the two rectangular templates (9) on the other side of the U-shaped inner template (5), and the dovetail block (30) is clamped in the dovetail slot (28), and the connecting plate (31) is clamped in the F-shaped support block (29). The connecting plate (31) is fixed with the fixing pin (33), thereby fixing the second side template (26). After installation, use nails or other fixing tools to firmly fix the formwork to the road surface or the preset supporting structure. Make sure the joints between the formwork are tight and seamless to prevent concrete leakage. S3: Concrete pouring (1) Concrete mixing Pour the prepared concrete materials into the mixer and mix them according to the ratio required by the design. During the mixing process, ensure that the concrete is uniform and free of lumps. (2) Concrete transportation Use transport vehicles to deliver the mixed concrete to the construction site. During transportation, it is necessary to ensure that the concrete does not undergo segregation or stratification. (3) Concrete pouring Pour the concrete evenly into the installed steel formwork. During the pouring process, the pouring speed must be controlled to prevent formwork deformation or concrete accumulation. The concrete is vibrated with a vibrator to remove air bubbles and increase density. When the molding temperature is too low to affect the molding, it is only necessary to pour hot water from outside into the water inlet pipe (18), so that the hot water is stored inside the heat-insulating shell (17), thereby increasing the temperature inside the formwork, thereby forming a constant temperature curing environment, shortening the concrete growth time, and accelerating the turnover of the formwork. S4: Formwork removal and maintenance (1) Template removal The formwork can only be removed after the concrete reaches the design strength. When removing the formwork, follow the principle of top first, bottom later, outside first, inside later to avoid damaging the concrete components. (2) Maintenance The poured concrete components are maintained to ensure that they reach the design strength within the specified time. During the curing process, the concrete surface must be kept moist to prevent it from drying out and cracking. S5: Quality Inspection and Acceptance (1) Quality inspection During the construction process, the quality of the concrete, the installation position of the formwork, the levelness, etc. must be checked regularly. Problems discovered should be rectified promptly to ensure that construction quality meets design requirements. (2) Acceptance After the construction is completed, relevant personnel will be organized to conduct acceptance inspection. The acceptance content includes whether the size, shape, strength, etc. of the concrete components meet the design requirements. Only after passing the acceptance test can the next step of construction or commissioning be carried out.
