Description

Technical Field

[0001] This utility model relates to the field of concrete rainwater pipe structures, and in particular to a sealing structure for concrete rainwater pipes. Background Technology

[0002] A concrete rainwater pipe sealing structure is a structural form or technical solution specifically designed to improve the sealing performance of concrete rainwater pipe connections. The core purpose of this structure is to effectively prevent rainwater leakage at pipe connections, ensuring the stable and efficient operation of the entire drainage system and avoiding various problems caused by leakage.

[0003] For flat-end concrete pipes, the structural design of their joints typically consists of two main parts: an outer and an inner seal. Firstly, the outer seal primarily comprises a reinforcing mesh and a layer of cement mortar covering it. The reinforcing mesh provides necessary support and fixation; however, its construction is complex and inconvenient, and it is prone to displacement or abnormal movement during actual construction, undoubtedly increasing construction difficulty and potential quality risks. Secondly, the inner seal mainly uses a layer of cement mortar for joint sealing. While this method provides a certain degree of sealing, its strength is relatively low, and in certain situations, it may not simultaneously meet the requirements of sealing performance and structural strength, leading to poor sealing and even leakage. Therefore, improving the strength and reliability of the sealing structure while ensuring ease of construction has become an important direction for current technological improvements. Utility Model Content

[0004] The main purpose of this utility model is to provide a sealing structure for concrete rainwater pipes, which aims to solve the problems of inconvenient construction and poor sealing effect of concrete rainwater pipe sealing structures.

[0005] To achieve the above objectives, this utility model provides a concrete rainwater pipe sealing structure, comprising: Two flat-headed concrete pipes are coaxially aligned, and the outer and inner walls of the inner ends of the flat-headed concrete pipes along their length are both machined with pit rings composed of multiple recesses. Two sealing rings are clamped between the inner ends of the two flat-headed concrete pipes along their length. An inner steel mesh is provided on the inner wall of the joint between the two flat-end concrete pipes, and the inner steel mesh covers the two sealing rings and the pit rings of the two flat-end concrete pipes; An outer steel mesh is provided on the outer wall of the joint of the two flat-end concrete pipes, and an inner steel mesh covers the two sealing rings and the pit rings of the two flat-end concrete pipes; Multiple binding wires are clamped between the two sealing rings and spaced apart in the circumferential direction, and the binding wires connect the inner steel mesh and the outer steel mesh. An outer cement mortar layer is bonded to the outer wall of the two flat-headed concrete pipes and covers the outer steel mesh in terms of thickness and length; An inner cement mortar layer is bonded to the inner wall of the two flat-headed concrete pipes and covers the inner steel mesh in terms of thickness and length.

[0006] Furthermore, the cross-section of the integral structure formed by the two sealing rings is I-shaped, thus wrapping the end faces of the two flat-headed concrete pipes.

[0007] Furthermore, both the inner and outer reinforcing mesh tubes are circumferentially connected in a half-connection structure and are connected by the binding wire.

[0008] Furthermore, the diameter of the reinforcing bars that make up the inner and outer reinforcing mesh cylinders is in the range of 1 to 5 millimeters.

[0009] Furthermore, the thickness of the sealing ring is 2 to 4 millimeters.

[0010] Furthermore, the sealing ring is made of polyethylene and polypropylene.

[0011] Furthermore, the length of the inner and outer reinforcing mesh tubes is 10 to 15 centimeters.

[0012] Furthermore, the thickness of the outer cement mortar layer is 1 to 3 cm, and the thickness of the inner cement mortar layer is 1 to 2 cm.

[0013] Furthermore, the recess is post-machined into the flat-head concrete pipe.

[0014] Furthermore, adjacent binding wires are spaced 10 to 20 degrees apart in the circumferential direction.

[0015] The concrete rainwater pipe sealing structure provided by this utility model provides a sealing effect by having two sealing rings clamped between the inner ends of two flat-end concrete pipes along their length. Multiple binding wires are clamped between the two sealing rings and spaced apart in the circumferential direction, thus ensuring that the binding wires do not affect the sealing effect between the two flat-end concrete pipes. The binding wires connect the inner and outer reinforcing mesh, forming a mutual fixation between them. This significantly reduces the possibility of structural deformation of the inner and outer reinforcing mesh and completely avoids abnormal movement of their positions. Finally, the main sealing effect is provided by the outer and inner cement mortar layers. Attached Figure Description

[0020] Reference Figures 1 to 7 In one embodiment of this utility model, a concrete rainwater pipe sealing structure includes: Two flat-headed concrete pipes 100 are coaxially aligned, and the outer and inner walls of the inner ends of the flat-headed concrete pipes 100 in the length direction are both machined with pit rings composed of multiple pits. Two sealing rings 200 are clamped between the inner ends of the two flat-head concrete pipes 100 along their length. An inner steel mesh cylinder 300 is disposed on the inner wall at the joint of the two flat-end concrete pipes 100, and the inner steel mesh cylinder 300 covers the two sealing rings 200 and the pit rings of the two flat-end concrete pipes 100. The outer steel mesh 400 is set on the outer wall of the joint of the two flat-head concrete pipes 100, and the inner steel mesh 300 covers the two sealing rings 200 and the pit rings of the two flat-head concrete pipes 100. Multiple binding wires 500 are clamped between two sealing rings 200 and spaced apart in the circumferential direction, and the binding wires 500 connect the inner steel mesh tube 300 and the outer steel mesh tube 400. An outer cement mortar layer 600 is bonded to the outer wall of the two flat-head concrete pipes 100 and covers the outer steel mesh cylinder 400 in terms of thickness and length. An inner cement mortar layer 700 is bonded to the inner walls of the two flat-head concrete pipes 100 and covers the inner steel mesh cylinder 300 in terms of thickness and length.

[0021] In existing technologies, concrete rainwater pipe sealing structures are inconvenient to construct and have poor sealing effects.

[0022] The concrete rainwater pipe sealing structure provided by this utility model includes two flat-end concrete pipes 100, two sealing rings 200, an inner steel mesh tube 300, an outer steel mesh tube 400, multiple binding wires 500, an outer cement mortar layer 600, and an inner cement mortar layer 700.

[0023] Two flat-end concrete pipes 100 are coaxially aligned to provide a foundation for docking. Both the outer and inner walls of the inner ends of the flat-end concrete pipes 100 along their length are machined with a groove ring consisting of multiple recesses. These recesses can be machined during the fabrication of the flat-end concrete pipes 100 or can be small groove structures chiseled out after the flat-end concrete pipes 100 are fully formed. The size of the recesses is adapted to the size of the flat-end concrete pipes 100. The groove ring along the length of the flat-end concrete pipes 100 can be approximately 10 centimeters.

[0024] Two sealing rings 200 are clamped between the inner ends of the two flat-end concrete pipes 100 along their length. The sealing rings 200 are made of materials such as polyethylene and polypropylene. The sealing effect between the two flat-end concrete pipes 100 is achieved by the two sealing rings 200.

[0025] The inner reinforcing mesh 300 is installed on the inner wall of the joint between two flat-end concrete pipes 100. The inner reinforcing mesh 300 covers two sealing rings 200 and the pit rings of the two flat-end concrete pipes 100. The outer reinforcing mesh 400 is installed on the outer wall of the joint between the two flat-end concrete pipes 100. The inner reinforcing mesh 300 covers two sealing rings 200 and the pit rings of the two flat-end concrete pipes 100. The diameter of the reinforcing bars forming the inner and outer reinforcing mesh 300 and 400 is in the range of 1 to 5 mm. Since the thickness of both the outer cement mortar layer 600 and the inner cement mortar layer 700 should not be too large, the diameter of the reinforcing bars forming the inner and outer reinforcing mesh 300 and 400 should not be too large, within the range of 1 to 2 mm. Especially when multiple binding wires 500 connect the inner and outer reinforcing mesh 300 and 400, a smaller reinforcing bar diameter will not increase the construction difficulty of the inner reinforcing mesh 300.

[0026] Multiple binding wires 500 are clamped between two sealing rings 200 and spaced apart circumferentially, ensuring that the binding wires 500 do not affect the sealing effect between the two flat-head concrete pipes 100. The binding wires 500 connect the inner steel mesh 300 and the outer steel mesh 400 by binding, forming a mutual fixation between them. This significantly reduces the possibility of structural deformation of the inner steel mesh 300 and the outer steel mesh 400, and completely avoids abnormal movement of their positions.

[0027] An outer cement mortar layer 600 is bonded to the outer walls of the two flat-end concrete pipes 100 and covers the outer reinforcing mesh 400 in terms of thickness and length. An inner cement mortar layer 700 is bonded to the inner walls of the two flat-end concrete pipes 100 and covers the inner reinforcing mesh 300 in terms of thickness and length. The outer cement mortar layer 600 and the inner cement mortar layer 700 provide the main sealing effect, while the inner reinforcing mesh 300 and the outer reinforcing mesh 400 facilitate the construction of the outer cement mortar layer 600 and the inner cement mortar layer 700, while improving the final structural strength.

[0028] In summary, the two sealing rings 200 are clamped between the inner ends of the two flat-end concrete pipes 100 along their length to provide a sealing effect; multiple binding wires 500 are clamped between the two sealing rings 200 and spaced apart in the circumferential direction, thus ensuring that the binding wires 500 do not affect the sealing effect between the two flat-end concrete pipes 100; the binding wires 500 connect the inner steel mesh 300 and the outer steel mesh 400, forming a mutual fixation between them, which greatly reduces the possibility of structural deformation of the inner steel mesh 300 and the outer steel mesh 400, and completely avoids abnormal movement of the inner steel mesh 300 and the outer steel mesh 400; finally, the outer cement mortar layer 600 and the inner cement mortar layer 700 provide the main sealing effect.

[0029] Reference Figures 4 to 7 In one embodiment, the cross-section of the integral structure formed by the two sealing rings 200 is I-shaped and wraps around the end faces of the two flat-head concrete pipes 100.

[0030] In this embodiment, the shape of the sealing ring 200 restricts the two sealing rings 200 to form a superior sealing effect on the end faces of the two flat-head concrete pipes 100.

[0031] In one embodiment, the inner steel mesh 300 and the outer steel mesh 400 are both half-connected structures in the circumferential direction and are connected by the binding wire 500.

[0032] Normally, the inner reinforcing mesh 300 and the outer reinforcing mesh 400 are connected circumferentially through welding or other methods, which increases the difficulty of the operation. In this embodiment, the inner reinforcing mesh 300 includes two sub-inner reinforcing meshes 300 with a circumferential angle of 180 degrees. Multiple binding wires 500 connect the inner reinforcing mesh 300 and the outer reinforcing mesh 400, and also connect the two sub-inner reinforcing meshes 300 to each other. The outer reinforcing mesh 400 includes two sub-outer reinforcing meshes 400 with a circumferential angle of 180 degrees. Multiple binding wires 500 connect the inner reinforcing mesh 300 and the outer reinforcing mesh 400, and also connect the two sub-outer reinforcing meshes 400 to each other. Although the connection strength between the two sub-inner reinforcing meshes 300 and the two sub-outer reinforcing meshes 400 is low in the above process, it provides a foundation for subsequent welding.

[0033] In one embodiment, the diameter of the reinforcing bars that make up the inner reinforcing mesh 300 and the outer reinforcing mesh 400 is in the range of 1 to 5 millimeters.

[0034] In this embodiment, the thickness of both the outer cement mortar layer 600 and the inner cement mortar layer 700 should not be too large. Therefore, the diameter of the reinforcing bars that make up the inner reinforcing mesh 300 and the outer reinforcing mesh 400 should not be too large, and can be within the range of 1 to 2 millimeters. Especially when there are multiple binding wires 500 connecting the inner reinforcing mesh 300 and the outer reinforcing mesh 400, a smaller reinforcing bar diameter will not increase the construction difficulty of the inner reinforcing mesh 300.

[0035] In one embodiment, the thickness of the sealing ring 200 is 2 to 4 millimeters.

[0036] In this embodiment, the thickness of the sealing ring 200 is limited. If the thickness of the sealing ring 200 is too small, it will not be enough to maintain the sealing effect at the binding wire 500; if the thickness of the sealing ring 200 is too large, it will be difficult for the sealing ring 200 to form a sealing effect and it will be prone to failure.

[0037] In one embodiment, the sealing ring 200 is made of polyethylene and polypropylene.

[0038] In this embodiment, polyethylene and polypropylene have a stable carbon-carbon backbone structure, which can resist oxidation, ultraviolet radiation and chemical corrosion, and maintain their performance even when exposed to humid or acidic / alkaline environments for a long time.

[0039] In one embodiment, the length of the inner steel mesh tube 300 and the outer steel mesh tube 400 is 10 to 15 centimeters.

[0040] In this embodiment, the lengths of the inner steel mesh 300 and the outer steel mesh 400 are limited, thereby increasing the dimensions of the outer cement mortar layer 600 and the inner cement mortar layer 700 in the length direction of the flat-end concrete pipe 100. As a result, a superior sealing effect is achieved at the joint of the two flat-end concrete pipes 100.

[0041] In one embodiment, the thickness of the outer cement mortar layer 600 is 1 to 3 cm, and the thickness of the inner cement mortar layer 700 is 1 to 2 cm.

[0042] In this embodiment, the thickness of the outer cement mortar layer 600 and the inner cement mortar layer 700 is limited to ensure the sealing effect while reducing abnormal effects on the fluid inside the pipe.

[0043] In one embodiment, the recess is post-machined into the flat-head concrete pipe 100.

[0044] In this embodiment, for example, after the flat-head concrete pipe 100 has been completely cured, the inner and outer walls of the flat-head concrete pipe 100 are chiseled out using a suitable tool.

[0045] In one embodiment, adjacent binding wires 500 are spaced 10 to 20 degrees apart in the circumferential direction.

[0046] In this embodiment, the circumferential spacing angle of the binding wires 500 is limited, thereby ensuring the connection effect between the inner steel mesh tube 300 and the outer steel mesh tube 400 while avoiding a significant increase in workload.

[0047] In summary, the concrete rainwater pipe sealing structure provided by this utility model provides a sealing effect by having two sealing rings 200 clamped between the inner ends of two flat-end concrete pipes 100 along their length; multiple binding wires 500 are clamped between the two sealing rings 200 and spaced apart in the circumferential direction, thus ensuring that the binding wires 500 do not affect the sealing effect between the two flat-end concrete pipes 100; the binding wires 500 connect the inner steel mesh 300 and the outer steel mesh 400, forming a mutual fixation between them, which greatly reduces the possibility of structural deformation of the inner steel mesh 300 and the outer steel mesh 400, and completely avoids abnormal movement of the inner steel mesh 300 and the outer steel mesh 400; finally, the main sealing effect is provided by the outer cement mortar layer 600 and the inner cement mortar layer 700.

[0048] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
