Description

Technical Field

[0001] The present application relates to the technical field of pipeline protection systems, and in particular to a casing system for protecting existing water pipes. Background Art

[0002] The casing system for protecting existing water pipes is a pipe protection system used to protect existing pipes from damage such as corrosion, physical damage, etc. Such casings are usually made of corrosion-resistant materials such as polyethylene, polyvinyl chloride (PVC), fiberglass reinforced plastics (FRP), etc., which can resist erosion by chemicals and water.

[0003] First, the condition of the existing pipe needs to be assessed to determine if protective sleeves need to be installed and what type of sleeves are required.

[0004] Second, choose the right material based on the environment the pipeline will be in and the specific risks it needs to protect against.

[0005] Again, accurately measure the size and length of the existing pipe to ensure that the sleeve piece can properly cover the entire pipe.

[0006] First, before installing the casing, the pipe needs to be cleaned and dried to ensure that there is no dust, grease or other contaminants on the surface.

[0007] Finally, follow the manufacturer's instructions for installation. Typically, the sleeve will be installed on the pipe by sliding it in or wrapping it around the pipe.

[0008] In addition, it is also necessary to ensure that the casing joints are well sealed to prevent moisture and other substances from penetrating; regularly check the condition of the casing to ensure that there is no damage or wear, and perform maintenance and replacement in a timely manner. Through these steps, water pipe fittings can be effectively protected, their service life can be extended, and maintenance costs can be reduced.

[0009] However, when the foundation settles, the existing pipeline protection system cannot provide secondary protection for the pipeline. Utility Model Content

[0010] The embodiment of the present application provides a casing system for protecting existing water pipes, thereby solving the problem in the prior art that the casing cannot provide secondary protection for the pipe when the foundation of the pipe protection system sinks.

[0011] An embodiment of the present application provides a casing system for protecting an existing water pipe, comprising a fluid protective layer and a casing member; the casing member is sleeved on the outer wall of the water pipe member; the water pipe member and the casing member are coaxial; a receiving space is formed between the inner wall of the casing member and the outer wall of the water pipe member; the fluid protective layer is arranged in part of the receiving space, and the thickness of the fluid protective layer does not exceed the radius of the water pipe member.

[0012] In a possible implementation manner, the fluid protection layer is a fine sand layer.

[0013] In a possible implementation manner, the diameter of the sleeve member is three times the diameter of the water pipe member.

[0014] In a possible implementation, the sleeve member includes a straight pipe and a corrugated connecting pipe; the corrugated connecting pipe is connected between the straight pipes.

[0015] In a possible implementation, a sponge is further included; the sponge is arranged at a portion of the accommodating space where the fluid protection layer is not arranged.

[0016] In a possible implementation, both ends of the sleeve member are detachably and fixedly connected with guide devices.

[0017] In a possible implementation, the guide device includes a sleeve embedment and two guide wheels; the sleeve embedment is embedded in the sleeve member port; the two guide wheels are rotatably connected to the sleeve embedment; the guide wheels are used to support the water pipe member to be introduced into the sleeve member and to make the water pipe member and the sleeve member coaxial.

[0018] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects: the embodiments of the present application provide a protection including a fluid protective layer and a sleeve member; the sleeve member is sleeved on the outer wall of the water pipe member; the water pipe member and the sleeve member are coaxial; a containing space is formed between the inner wall of the sleeve member and the outer wall of the water pipe member; the fluid protective layer is arranged in part of the containing space, and the thickness of the fluid protective layer does not exceed the radius of the water pipe member. Since the sleeve member is added outside the water pipe member, the existing water pipe member is effectively protected and the roadbed construction is convenient. Since the sleeve member wraps the existing water pipe member, and the water pipe member is located at the center of the sleeve member, and the distance from the inner wall of the sleeve member to the outer wall of the outer pipe is greater than the diameter of the water pipe member, the existing water pipe member can be prevented from being broken due to foundation settlement. Since the fluid protective layer is laid inside the sleeve member, when the foundation settles, the sleeve member breaks, and the fluid protective layer flows to the low-lying area, filling the sunken area under the water pipe member, which can effectively support the existing water pipe member and form secondary protection for the water pipe member.

[0026] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

The terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. In addition, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be a connection between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0028] like Figure 1As shown, the casing system for protecting the existing water pipe provided in the embodiment of the present application includes a fluid protection layer 3 and a casing member 2. The casing member 2 is sleeved on the outer wall of the water pipe member 1. The water pipe member 1 and the casing member 2 are coaxial. A holding space is formed between the inner wall of the casing member 2 and the outer wall of the water pipe member 1. A fluid protection layer 3 is provided in part of the holding space, and the thickness of the fluid protection layer 3 is not greater than the radius of the water pipe member 1. The embodiment of the present application adopts the casing system for protecting the existing water pipe provided. Since the casing member 2 is provided outside the water pipe member 1, the existing water pipe member 1 is effectively protected, which facilitates the roadbed construction. Since the casing member 2 wraps the existing water pipe member 1, and the water pipe member 1 and the casing member 2 are coaxial, the distance from the inner wall of the casing member 2 to the outer wall of the outer pipe is greater than the diameter of the water pipe member 1. When the existing water pipe member 1 is broken due to foundation settlement, the fluid protection layer 3 inside the casing member 2 flows to the broken part, effectively supporting the existing water pipe member 1, and forming secondary protection for the water pipe member 1.

[0029] like Figure 1 As shown, the fluid protection layer 3 is a fine sand layer.

[0030] The embodiment of the present application adopts the provided casing system for protecting the existing water pipe and uses fine sand as the fluid protection layer 3, so as to achieve the purpose of good effect and low cost.

[0031] like Figure 1 As shown, in the casing system for protecting an existing water pipe provided by the embodiment of the present application, the diameter of the casing component 2 is three times the diameter of the water pipe component 1 .

[0032] The embodiment of the present application adopts the provided casing system for protecting the existing water pipe. Since the diameter of the casing member 2 is three times the diameter of the water pipe member 1, the fluid protection layer 3 is arranged in the casing member 2 and supported at the bottom of the water pipe member 1. The water pipe member 1 is located at the center of the casing member 2. When the foundation settles, a reserve of twice the diameter of the water pipe member 1 is reserved between the casing member 2 and the water pipe member 1. When the casing member 2 breaks, the fluid protection layer 3 can flow toward the direction of the lower terrain to continue to support the water pipe member 1.

[0033] like Figure 2 As shown, the casing system for protecting an existing water pipe provided in the embodiment of the present application, the casing member 2 includes a straight pipe 21 and a corrugated connecting pipe 22. The corrugated connecting pipe 22 is connected between the straight pipes 21.

[0034] The embodiment of the present application adopts a casing system for protecting existing water pipes. Since the corrugated connecting pipe 22 is used to connect the straight pipes 21, when the foundation settlement position is at the position of the corrugated connecting pipe 22, the setting of the present application can prevent the casing 2 from breaking, thereby causing the fluid protective layer 3 to flow out of the casing 2.

[0035] like Figure 1As shown, the casing system for protecting an existing water pipe provided in an embodiment of the present application further comprises a sponge 5. The sponge 5 is arranged at a position in the accommodation space where the fluid protection layer 3 is not arranged.

[0036] In the casing system for protecting an existing water pipe provided in the embodiment of the present application, the sponge 5 is arranged between the water pipe member 1 and the casing member 2 where the fluid protection layer 3 is not arranged. The sponge 5 can have a buffering effect on the water pipe member 1 when the foundation sinks, and has a protective effect on the water pipe member 1.

[0037] like Figure 3 , Figure 4 and Figure 5 As shown, in the embodiment of the present application, a casing system for protecting an existing water pipe is provided, and both ends of the casing member 2 are detachably and fixedly connected with a guide device 4.

[0038] The embodiment of the present application provides a casing system for protecting an existing water pipe, wherein the guide device 4 provides positioning guidance when the casing member 2 is installed on the water pipe member 1, so that the water pipe member 1 is located at the center of the casing member 2.

[0039] like Figure 3 , Figure 4 and Figure 5 As shown, the casing system for protecting an existing water pipe provided by the embodiment of the present application, the guide device 4 includes a casing insert 42 and two guide wheels 41. The casing insert 42 is embedded in the end of the casing member 2. The two guide wheels 41 are rotatably connected to the casing insert 42. The guide wheels 41 are used to support the water pipe member 1 to be introduced into the casing member 2 and make the water pipe member 1 and the casing member 2 coaxial.

[0040] In the casing system for protecting an existing water pipe provided in the embodiment of the present application, the guide wheel 41 is used to support the water pipe member 1 to be introduced into the casing member 2 and to make the longitudinal section of the water pipe member 1 be located at the center of the longitudinal section of the casing member 2. The casing insert 42 fixes the two guide wheels 41 at the ends of the casing member 2, and the water pipe member 1 can slide into the casing through the two guide wheels 41, and the water pipe member 1 and the casing member 2 can be coaxial.

[0041] When the casing member 2 and the water pipe member 1 are installed, the guide device 4 is installed at both ends of the casing member 2 through the casing inserts 42 at both ends of the water pipe member 1, and then the water pipe member 1 is slid into the casing member 2 through the guide wheels 41, so that the longitudinal section of the water pipe member 1 is at the center of the longitudinal section of the casing member 2. Then, the fluid protective layer 3 is injected into the casing member 2. When the fluid protective layer 3 can support the water pipe member 1 and make the longitudinal section at the center of the longitudinal section of the casing member 2, the guide device 4 is removed.

[0042] When an earthquake or other reasons cause the foundation to sink slightly, if the casing 2 of that section of the foundation also sinks or breaks, the fluid protective layer 3 in the casing 2 will flow to the sunken or broken part of the casing 2 due to gravity, continuing to support the water pipe 1 and providing secondary protection.

[0043] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other. Each embodiment focuses on the differences from other embodiments.

[0044] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit the present application. Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some or all of the technical features thereof may be replaced by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the present application.
