Description

Technical Field

[0001] This invention relates to the field of water tank construction technology, specifically a method for reinforcing waterproof sleeves in industrial water tanks. Background Technology

[0002] In industrial production projects, reinforced concrete industrial water tanks installed above ground are commonly used. These tank structures require the installation of various process pipelines, and waterproof sleeves need to be pre-embedded where the pipelines penetrate the tank walls. During the sleeve pre-embedding construction phase, corresponding reinforcement measures need to be taken to constrain the spatial position of the sleeves and prevent displacement during concrete pouring.

[0003] Currently, the majority of on-site reinforcement of waterproof sleeves involves welding additional reinforcing bars. On-site welding requires skilled personnel and equipment, involves numerous steps, and incurs material consumption. To secure the sleeve, a large number of reinforcing bars need to be laid around it, which can lead to densely packed reinforcement in certain areas. Excessive reinforcement can compress the space for concrete pouring and vibration, hindering proper compaction around the sleeve and potentially causing concrete quality defects.

[0004] The water tank is used to store various process media, and the density of the tank wall concrete directly affects its overall impermeability. If there are quality defects in the concrete around the casing, the media will leak along the defective locations, adversely affecting the surrounding soil and groundwater. Furthermore, the reinforcement method using welded steel bars means that after the casing concrete is poured, the reinforcing bars are embedded inside the tank wall concrete, making the components non-removable and recyclable; the materials are for single-use only. In addition, after the welded reinforcement structure is installed, the space for fine-tuning the casing's elevation and horizontal position is limited, making it difficult to continue correcting and adjusting the casing position after the formwork is closed, thus posing challenges to the positional accuracy control of the pre-embedded casing. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a construction method for reinforcing waterproof sleeves in industrial water tanks that avoids excessively dense reinforcement.

[0006] The technical solution adopted by this invention to solve its technical problem is:

[0007] A method for reinforcing waterproof sleeves in industrial water tanks, comprising the following specific steps:

[0008] S1: Processing and binding the steel bars on the sidewalls of the industrial water tank;

[0009] S2: Place the pre-embedded sleeve at the elevation and plane position corresponding to the design of the side wall, complete the pre-positioning installation of the templates on both sides of the side wall of the water tank, and temporarily stabilize the pre-embedded sleeve;

[0010] S3: Two annular steel plates are pre-installed on both sides of the pre-embedded sleeve. Multiple tie holes are pre-installed on the annular steel plates. Tie rods pass through the tie holes. The two annular steel plates are tightly attached to the outer surface of the template. Locking nuts that abut against the outer side of the annular steel plates are screwed onto the tie rods.

[0011] S4: Two positioning steel plates are respectively placed at the ends of the pre-embedded sleeve. A circular clamping plate is set on the inner side of the positioning steel plate. The outline size of the circular clamping plate matches the inner diameter of the pre-embedded sleeve. The circular clamping plate is inserted into the end of the pre-embedded sleeve to realize the alignment and limiting of the positioning steel plate. Multiple connecting holes are opened on the positioning steel plate, which are opposite to the tie holes. The tie rod passes through the connecting holes, and a locking nut that abuts against the outer side of the positioning steel plate is screwed on the tie rod.

[0012] S5: Multiple redundant nuts are welded on the outer side of the positioning steel plate. The positioning steel plate has through holes that are opposite to the center of the redundant nuts. Support bolts are screwed into the redundant nuts. The screw end of the support bolt passes through the through hole and abuts against the surface of the annular steel plate.

[0013] S6: The spatial position of the pre-embedded sleeve is corrected by adjusting the tightness of the water-stop tie rod and the support bolt. The elevation and plane position of the pre-embedded sleeve are checked and verified. After the check and verification are qualified, the support and reinforcement work of the inner side wall formwork of the water tank is carried out.

[0014] S7: Pour concrete into the completed formwork. After the concrete reaches the design strength, remove the side wall formwork of the pool and remove the redundant support bolts, positioning steel plates, ring steel plates and water-stop tie rods in sequence to complete the dismantling and recycling of all components of the reinforcement assembly.

[0015] The present invention, which adopts the above technical solution, has the following prominent features compared with the prior art:

[0016] This method utilizes a reinforcement assembly consisting of a detachable annular steel plate, a positioning steel plate, tie rods, and support bolts to achieve the positioning constraint of the pre-embedded sleeve. This eliminates the need for on-site welding of the reinforcement frame, simplifies on-site construction, reduces the number of personnel required, and eliminates the need for additional reinforcement bars around the sleeve, thus reducing steel consumption. The reinforcement assembly can be disassembled and removed after the concrete has solidified, allowing for reuse and aligning with green construction requirements. Eliminating the need for dense reinforcement bars improves the local reinforcement arrangement of the pool wall, providing more space for concrete vibration around the sleeve and reducing the possibility of concrete quality defects. This helps maintain the impermeability of the pool wall concrete, reducing the possibility of media leakage and impacting the surrounding water and soil environment. Furthermore, the method avoids on-site hot work and welding, reducing safety hazards associated with hot work operations.

[0017] As a preferred embodiment, a further technical solution of the present invention is:

[0018] Preferably, in S2, the temporary stabilization of the embedded sleeve is achieved by temporary binding and limiting. This can provide initial constraint on the embedded sleeve before the reinforcement components are assembled, preventing displacement of the sleeve during the assembly process and facilitating the subsequent alignment and installation of the reinforcement components.

[0019] Preferably, in S3, at least four tie holes are equally spaced along the ring of the annular steel plate. The tie holes distributed along the ring can make the stress distribution of the annular steel plate more balanced, reduce the risk of component skewing caused by local stress concentration, and improve the stability of the annular steel plate under clamping force.

[0020] Preferably, in S5, at least four redundant nuts are equally spaced along the ring on the positioning steel plate, and the redundant nuts and connecting holes are staggered. The staggered arrangement of redundant nuts and connecting holes can disperse the supporting force borne by the positioning steel plate from the supporting bolts, which are redundant supporting operating components, reduce the local stress concentration of the components, facilitate the smooth transmission of force between the positioning steel plate and the ring steel plate, and improve the reliability of the sleeve constraint state.

[0026] The present invention will be further illustrated below with reference to specific embodiments. The purpose of this illustration is solely to provide a better understanding of the invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0027] like Figures 1 to 4 As shown in the figure, this embodiment provides a construction method for reinforcing waterproof sleeves in industrial water tanks. The specific steps are as follows:

[0028] S1: Process and tie the steel bars on the side wall of the industrial water tank; the steel bar processing and tying operation shall be carried out in accordance with the project design drawings and current construction specifications. After the tying is completed, check the steel bar layout and the reserved space of the protective layer to confirm that there is no steel bar interference with the installation of the pre-embedded sleeve 1 before proceeding to the next process.

[0029] S2: Place the pre-embedded sleeve 1 at the elevation and plane position corresponding to the design of the side wall, complete the pre-positioning installation of the templates on both sides of the pool side wall, and temporarily stabilize the pre-embedded sleeve 1; the template pre-positioning only achieves the template to be roughly in place, without final compression and locking, and leaves a small adjustment margin between the template and the pool wall reinforcement, so as not to form a hard obstruction to the subsequent position adjustment of the pre-embedded sleeve 1;

[0030] S3: Two annular steel plates 2 are pre-installed on both sides of the pre-embedded sleeve 1. Multiple tie holes 21 are pre-installed on the annular steel plates 2. Tie screws 3 pass through the tie holes 21. The two annular steel plates 2 are respectively attached to the outer surface of the template. Locking nuts that abut against the outer side of the annular steel plates 2 are screwed onto the tie screws 3.

[0031] S4: Two positioning steel plates 4 are respectively placed at the ends of the pre-embedded sleeve 1. A circular clamping plate 5 is set on the inner side of the positioning steel plate 4. The outline size of the circular clamping plate 5 matches the inner diameter of the pre-embedded sleeve 1. The circular clamping plate 5 is inserted into the end of the pre-embedded sleeve 1 to realize the alignment and limitation of the positioning steel plate 4. Multiple connecting holes 41 are opened on the positioning steel plate 4, which are opposite to the tie holes 21. The tie screw 3 passes through the connecting holes 41. A locking nut that abuts against the outer side of the positioning steel plate 4 is screwed on the tie screw 3. The circular clamping plate 5 is embedded in the end of the pre-embedded sleeve 1. The radial limitation of the positioning steel plate 4 is realized by the contact between the outer wall of the clamping plate and the inner wall of the sleeve. The plate surface of the positioning steel plate 4 is in contact with the end face of the pre-embedded sleeve 1. Tightening the locking nut makes the positioning steel plate 4 initially clamped, leaving a small adjustment margin.

[0032] S5: Multiple redundant nuts 6 are welded to the outer surface of the positioning steel plate 4. The positioning steel plate 4 has through holes that are opposite to the center of the redundant nuts 6. Support bolts 7 are screwed into the redundant nuts 6. The screw end of the support bolt 7 passes through the through hole and abuts against the surface of the annular steel plate 2. The support bolt 7 serves as a redundant abutting operating component in addition to the locking of the tie rod 3. The screw end forms a surface contact with the surface of the annular steel plate 2. During the assembly process, the support bolt 7 is prevented from being skewed, ensuring that the abutting force can be vertically transmitted to the surface of the annular steel plate 2.

[0033] S6: The spatial position of the pre-embedded sleeve 1 is corrected by adjusting the tightness of the tie rod 3 and the support bolt 7. The elevation and plane position of the pre-embedded sleeve 1 are checked and verified. After the check and verification are qualified, the support and reinforcement work of the inner side wall formwork of the water tank is carried out.

[0034] S7: Pour concrete into the completed formwork. After the concrete reaches the design strength, remove the formwork of the side wall of the pool. Then, remove the support bolts 7, positioning steel plates 4, ring steel plates 2, and tie rods 3 in sequence to complete the dismantling and recycling of all components of the reinforcement assembly. During the concrete pouring process, avoid direct impact of the vibrating equipment on the reinforcement assembly and the pre-embedded sleeve 1 to prevent the sleeve from shifting due to external force disturbance. The component dismantling sequence should follow the order of first removing the bolt components and then removing the steel plate components. Do not violently strike the components during the dismantling process to prevent plastic deformation of the components.

[0035] Preferably, in S2, the embedded sleeve 1 is temporarily secured by a temporary binding and limiting method, which can provide a preliminary constraint effect on the embedded sleeve 1 before the reinforcement components are assembled, avoid displacement of the sleeve during the assembly process, and facilitate the subsequent alignment and installation of the reinforcement components.

[0036] Preferably, in S3, at least four tie holes 21 are equally spaced along the ring on the annular steel plate 2. The tie holes 21 distributed along the ring can make the force distribution of the annular steel plate 2 more balanced, reduce the risk of component skewing caused by local stress concentration, and improve the stability of the clamping force of the annular steel plate 2.

[0037] Preferably, in S5, at least four redundant nuts 6 are equally spaced along the ring on the positioning steel plate 4, and the redundant nuts 6 and the connecting holes 41 are staggered. The staggered arrangement of the redundant nuts 6 and the connecting holes 41 can disperse the abutting force borne by the positioning steel plate 4 from the support bolts 7, which are redundant abutting operating components, reduce the local force concentration of the components, facilitate the smooth transmission of force between the positioning steel plate 4 and the ring steel plate 2, and improve the reliability of the sleeve constraint state.

[0038] This method utilizes a reinforcement assembly consisting of a detachable annular steel plate 2, a positioning steel plate 4, tie rods 3, and support bolts 7 to complete the positioning constraint of the pre-embedded sleeve 1. This eliminates the need for on-site welding of the reinforcement frame, simplifies on-site construction, reduces the number of personnel required for corresponding trades, and avoids the need for adding a large number of reinforcing bars around the sleeve, thus reducing the consumption of steel materials. The reinforcement assembly can be disassembled and removed after the concrete has been formed, enabling the reuse of components and meeting the requirements of green construction. Eliminating the need for dense reinforcing bars improves the local reinforcement arrangement of the pool wall, leaving working space for concrete vibration around the sleeve, reducing the possibility of concrete quality defects around the sleeve, and helping to maintain the impermeability of the pool wall concrete itself. This reduces the possibility of media leakage affecting the surrounding water and soil environment. At the same time, the operation avoids on-site hot work and welding operations, reducing the safety hazards caused by hot work on the construction site.

[0039] The above description is merely a preferred embodiment of the present invention and does not limit the scope of the present invention. All equivalent changes made based on the description and drawings of the present invention are included within the scope of the present invention.
