Description

Technical Field

[0001] The utility model relates to the technical field of gas pipeline protection, in particular to an integrated module for gas pipeline protection. Background Technique

[0002] The main materials of existing buried gas pipelines are welded steel pipes or PE pipes. The steel pipes are characterized by high strength but poor corrosion resistance, and their service life is about 20 years. The PE pipes are characterized by corrosion resistance, long service life and low strength. According to the statistics of the leakage causes of operating gas pipelines, most of them are the violent damages caused by third-party construction. Because the warning tape is made of yellow plastic tape, it is easily damaged by excavators and not noticed. Whether it is a steel pipe or a PE pipe, it is also easily damaged under the impact of a hydraulic breaker, resulting in serious consequences such as gas leakage. Some are due to corrosion perforation and stray current corrosion. Content of the Utility Model

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figure 1 , the present utility model provides an integrated module for protecting a gas pipeline, including:

[0022] Gas supply PE pipeline 1;

[0023] Steel casing 2, the surface of which is coated with an anti-corrosion coating and is sleeved outside the gas supply PE pipeline 1;

[0024] Warning steel plate 3, which is arranged flush with the ground above the gas supply PE pipeline 1; and,

[0025] Intermediate layer 4, which is arranged between the gas supply PE pipeline 1 and the warning steel plate 3.

[0026] In this embodiment, it has both the strength of the steel pipe and the characteristics of the long corrosion resistance life of the PE pipe. The design of the steel casing 2 is mainly to facilitate the later maintenance. For example, when passing through roads and sections of roads, the pipe can be replaced by excavating the green belt, avoiding excavating the road and having less impact on traffic.

[0027] Modular design, easy to assemble, processed in the factory, with a good working environment, and more firm and accurate in terms of density, etc. than on-site construction; the modular construction structure is delicate and reliable, shortening the construction period and improving work efficiency.

[0028] In one embodiment, a rubber cushion layer 5 is provided at the bottom of the gas supply PE pipe 1. This setting in this embodiment can provide further protection for the gas supply PE pipe 1 and prevent impact or other forms of damage at the bottom of the gas supply PE pipe 1.

[0029] In one embodiment, the middle layer 4 is a stone powder block mixed with cement. The stone powder block mixed with cement in the middle layer and the rubber cushion layer 7 at the bottom layer can be cut and adjusted in shape according to the on-site situation to adapt to the complex environment of the construction site.

[0030] In one embodiment, it further includes a leak detection reserved pipe 6. One end of the leak detection reserved pipe 6 is connected to the gas supply PE pipe 1, and the other end extends to the ground. This setting in this embodiment can quickly detect whether there is air leakage through the leak detection reserved pipe. If there is a buried valve well, a gas leakage remote device can be set up to automatically alarm.

[0031] In one embodiment, it further includes a sensor 7, and the line connecting the sensor 7 is arranged in the optical fiber tube 8. This setting in this embodiment can give an early warning in time when the land above the gas supply PE pipe 1 is excavated, notify the operation and maintenance personnel, and avoid damaging the pipeline. Specifically, the sensor 7 uses a commonly used vibration sensor on the market.

[0032] In one embodiment, the steel casing 2 is a segmented splicing structure, and the splicing ends of adjacent steel casings 2 are connected by flanges and locking bolts. This setting in this embodiment facilitates the quick installation of the steel casing 2 on the gas supply PE pipe 1 and improves the installation efficiency.

[0033] Specifically, a sealing ring is provided between adjacent steel casings 2. This setting in this embodiment improves the sealing performance between adjacent steel casings 2 and can prevent water accumulation or foreign objects from entering the steel casing 2.

[0034] Specifically, the usage method of this device is as follows:

[0035] All modules except the gas supply PE pipe are processed in the factory in advance, and the modules are transported to the site for assembly; then the module assembly is adjusted according to the on-site situation. If there are stations or office buildings nearby where a vibration emission device can be placed, an optical fiber can be placed in the optical fiber sleeve to form a loop, and the excavation vibration above can automatically alarm and notify the operation and maintenance personnel.

[0036] Due to the presence of other pipelines or obstacles at the site, when the excavation of the ditch is not so ideal, the cement-mixed stone powder blocks in the middle layer and the thick rubber soft base layer at the bottom layer can be cut and adjusted in shape according to the site conditions to adapt to the complex construction environment.

[0037] If the burial depth does not meet the specification requirements or in key parts such as crossing roads, first weld the steel casing, then use a heat shrinkable sleeve for anti-corrosion, and finally put the PE pipe in. The steel casing does not need to be welded in other parts, and the gas supply pipe is connected. In case of special situations such as air leakage, the PE pipes at both ends of the module can be directly cut off and the whole module can be replaced.

[0038] The inspection personnel can quickly detect whether there is air leakage by using a handheld device or a detection vehicle to detect through the leakage detection reserved pipe. In case of a buried valve well, a remote gas leakage device can be set up to give an automatic alarm.

[0039] It should be noted that if there are directional indications such as up, down, left, right, front, back... in the embodiments of the present invention, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture as shown in the drawings. If the specific posture changes, the directional indications will also change accordingly.

[0040] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing throughout the text includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or a solution that satisfies both A and B at the same time. In addition, "a plurality" means more than two. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those skilled in the art can implement them. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist.

[0041] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
