Description

- 1 - TARIFF LEAKPROOF CONNECTION SLEEVE FOR INFRASTRUCTURE MANHOLE SHAFTS Technical Area The invention relates to the technical field of infrastructure construction and infrastructure line crossing systems. especially in manhole covers where sewage, rainwater and electrical lines pass 5 ensuring corrugated pipes are connected to the chimney wall in a leak-proof and secure manner. It relates to a connecting sleeve that provides a connection. Previous Technique In current practices, corrugated pipe lines are installed in manhole covers. Various methods are used in its connection. These methods, in general... connecting the pipeline to the manhole and sealing the connection area. Although the aim is to provide this, the solutions used do not offer long-term durability and surface finish. It has significant shortcomings in terms of compatibility. One common method is to set the manhole bases at factory-fixed pipe outlet angles of 15. They are manufactured according to a predetermined angle. Because these bases are produced with predetermined angles, The actual pipe approach angle in the field often does not coincide with this fixed angle. This Incompatibility may lead to strain on the connection or additional cutting / breaking work on site. This creates a need for such renovations. These types of renovations both weaken the structure and cause structural problems. and it also increases the risk of leakage. 20 Another method involves drilling a hole in the manhole cover and sealing it from the outside. adapters are inserted and the pipe is pushed into this seal using a push-fit method. These elastomer-based gaskets age over time, It undergoes deformation and is not fully formed due to the limited thickness of the body. It cannot maintain surface contact. This situation results in a 25% loss of watertightness in the long term. This leads to its deterioration. One of the methods frequently encountered in practice is the on-site inspection of the manhole cover. cutting or puncturing and filling the resulting gap with polyurethane foam It is filled and then sealed with mortar. Although this method seems practical... There is a material incompatibility between the plastic manhole surface and the concrete mortar, 30 Cracks due to varying thermal expansion values ​​and ground movements. This leads to formation and leakage. Furthermore, these types of solutions are standard. It is external and does not provide a permanent seal. - 2 - Externally mounted pipes are used in some applications of thermoplastic pipelines. Adapters are preferred; however, these adapters are specifically designed for manhole covers. Because it was not designed that way, it cannot adapt to the inner surface curve of the manhole. This type Adapters require electrofusion or boiling, therefore in field conditions. presenting a challenge and a fully fitting monoblock connection surface from the inside 5 It does not offer. The common problem with these known techniques is the connection between the manhole cover and the corrugated pipe line. among them those that can adapt to field conditions and perfectly match the manhole inner surface curve. a fitted, internally seated, sealing device that loosens or weakens over time. The absence of a monolithic connecting element that will not separate. This 10 Therefore, current methods can lead to leakage, loosening, and ground subsidence in the long term. This leads to problems such as structural deformation and maintenance difficulties. Brief Description of the Invention Our invention, corrugated pipes, is used in manhole covers and infrastructure line crossings. 15 Developed for this purpose, it provides a complete seal, is easy to install, and has a long lifespan. It is a new generation connecting sleeve that does not undergo deformation over time. The sleeve Thanks to its guiding internal geometry, the assembly process is completed quickly. in progress, errors may arise during implementation depending on the level of proficiency. The probability of it coming out is greatly reduced. This guiding structure, corrugated 20 The connection ensures the pipe finds its own path and sits at the correct angle. No gaps are formed in the area, ensuring a complete seal. The invention's unique inner surface form and its outer surface that comes into contact with the manhole cover surface. compatible operation, performance loss over time such as with mortar and polyurethane foam It completely eliminates the need for materials that create it. Thus, both 25 The assembly process is simplified, and chemical fillers can crack over time. Leakage and deformation problems that occur are prevented. In addition, in existing techniques frequently seen recycled polyethylene with different raw material structures Pipe adhesion problems do not occur thanks to this design; Preventing loosening and leaks caused by raw material incompatibility 30 It will be over. Another important technical advantage offered by the invention is the time efficiency in the connection area. The goal is to prevent loosening, deformation, or separation that may occur. This feature can occur due to ground movements, groundwater effects, or conditions that may develop under load. - 3 - It ensures the preservation of connection integrity against structural stresses. Thus, both the safety of both the manhole and the surrounding ground, road and foundation areas increases; in the long term, ground subsidence, subsidence-related damage, and leaks It disappears. The coupling's robust and stable connection structure facilitates maintenance and unclogging. 5 It also offers significant advantages in operations. The connection area is stable and leak-proof. This allows for safe and rapid intervention on the pipeline. It recognizes. When all these features are combined, the invention has a long lifespan in infrastructure systems. long-lasting, high-strength, reduces maintenance costs, and is environmentally and structurally sound. It offers an innovative connectivity solution that eliminates risks. 10 DESCRIPTION OF THE FIGURES Figure 1 - Main Body of Manhole Without Sleeve Attachment Figure 2 - Perspective View of the Coupling Figure 3 - The point where the corrugated pipe and manhole main body are joined with a sleeve.

Coupling 20 Detailed Description of the Invention The invention is for leakproof corrugated pipes (2) used in infrastructure manhole covers, to be connected to the main body of the manhole (1) in a secure and long-lasting manner It relates to a sleeve (3) structure that provides. The forms of application of the invention are shown in Figure 25. This has been explained through [link / method]. 1. Main Structure and General Function The subject of the invention is the sleeve (3), the main body of the manhole (1) and the corrugated pipe (2) It is a transition element that provides mechanical locking and complete sealing between them. The aim of the system is to replace the mortar, polyurethane foam, or 30 used in existing methods. Leakage that occurs in methods such as rotational compression assembly, The goal is to completely eliminate problems such as loosening and ground subsidence. - 4 - Coupling (3) attaches to both the main body of the manhole (1) and the corrugated pipe (2) Thanks to its geometry, it offers a self-assembling structure. This feature makes assembly both It speeds up the process and reduces dependence on skill level, thus preventing faulty assembly. It reduces the probability. 2.

It shows the main body of the manhole (1), where the sleeve (3) will be placed. It has a suitable socket geometry at the connection point. Thanks to this structure: The sleeve (3) sits flat on the chimney surface, eliminating the need for mortar, 10 The connection point does not loosen over time and the sealing surface is seamless. It provides contact. 3. Explanation According to Figure 2 — Structure of the Sleeve (3) Figure 2 is a perspective view of the sleeve (3) that is the subject of the invention. Sleeve (3): • An inner surface compatible with the outer profile of the corrugated pipe (2), 15 • The outer surface which ensures a tight fit to the chimney body (1), • Inlet geometry that guides the pipe during connection has. This inner surface form fits perfectly to the roller surface of the corrugated pipe (2). and creates a seal with the tight fit principle. 20 in the entry area of ​​the sleeve(3) The guiding surface helps the pipe find its own path during installation. This ensures that the corrugated pipe (2) does not get into the wrong angle during assembly. It aligns automatically. In addition, the sleeve (3) has an internal structure that leaves no unnecessary gaps. It has this feature, which minimizes the possibility of liquid leakage. 4.
