Buried thermal insulation pipeline convenient to detect and detection method thereof

Abstract

The invention discloses a buried thermal insulation pipeline convenient to detect and a detection method thereof, and belongs to the technical field of heat preservation pipelines. According to the scheme, a plurality of exploratory wells are additionally arranged on an outer pipe, when whether a heat preservation layer at a measuring point is affected with damp or not is checked, an exploring device is inserted into the exploratory wells, and whether the heat preservation layer at the position is affected with damp or not can be known through a display panel. Compared with a traditional method that a pipeline is dug out of soil for detection, a large amount of time and cost are saved, when it is detected that the humidity in the heat preservation layer is too large, the drying agent can be stuffed into the inner side of the outer pipe through the feeding pipe to absorb the humidity in the heat preservation layer, and meanwhile, when the drying agent absorbs the humidity in the heat preservation layer, the distinguishing device is arranged for monitoring whether the moisture content in the heat preservation layer is recovered normally; when the moisture content in the heat preservation layer returns to normal, the drying agent is taken out from the feeding pipe, so that the situation that the drying agent is located on the inner side of the heat preservation layer for a long time and pollutes the heat preservation layer is avoided.

Description

technical field [0001] The invention relates to the technical field of thermal insulation pipelines, and more specifically, relates to a buried thermal insulation pipeline that is easy to detect and a detection method thereof. Background technique [0002] Buried thermal insulation pipeline is a kind of thermal insulation pipeline buried underground, which has excellent characteristics such as high-efficiency thermal insulation, waterproof, anti-corrosion, heat insulation, sound insulation, flame retardant, cold resistance, anti-corrosion, light capacity, high strength, simple and fast construction, and not afraid of plant root thorns, etc. , Directly buried thermal insulation pipes are used for various indoor and outdoor pipelines, central heating pipelines, central air-conditioning pipelines, chemical, pharmaceutical and other industrial pipelines for thermal insulation, cold insulation projects, oil pipeline projects, steam transmission and other pipeline projects.

AI Technical Summary

Problems solved by technology

[0003] Existing thermal insulation pipelines usually consist of an outer tube, an inner tube, and a thermal insulation layer. Since the thermal insulation pipeline is buried underground, moisture will inevitably enter the interior of the thermal insulation layer. When there is a lot of moisture inside the thermal insulation layer, it will not only affect the thermal insulation effect of the pipeline , and may cause the insulation to rot, the existing solution is usually to dig the pipe out of the ground for repair

[0004] However, digging out the pipeline from the ground for maintenance not only brings great inconvenience, but also because the pipeline is buried in the ground, it is also possible that the wrong digging occurs because the damaged point cannot be confirmed, so further improvement is needed. In actual use found that when the insulation layer of the pipeline gets wet, the insulation effect of the insulation layer will decrease, and the temperature of the outer pipe will increase, which provides an improvement basis for the present invention
