Abstract
Description
Technical Field
[0001] The utility model relates to a gas pipeline laying groove structure. Background Art
[0002] During the construction of gas pipelines, it is necessary to excavate pipeline trenches. Although the soil is excavated, stacked and backfilled in layers during the construction process, the trenches are generally provided with a fireproof layer for fire prevention purposes. The insulating fireproof layer changes the original soil layer and texture, making the excavated soil discontinuous in structure and layer. The continuity of the soil is destroyed, which changes the energy flow pattern in the soil, making it difficult for the surface vegetation to return to its original state, especially in places where the ecosystem is more fragile, or when the original vegetation at the pipeline construction location is highly dependent on the soil, the restoration of vegetation is even more difficult. Utility Model Content
[0003] Based on this, the purpose of the utility model is to provide a trench structure for laying gas pipelines, reduce the impact of soil structure damage on energy flow in the soil, and accelerate the recovery of vegetation on the soil surface.
[0004] A gas pipeline laying trench structure includes a trench opened in the soil, wherein a laying layer and a backfill soil layer are arranged in sequence from bottom to top in the trench; the laying layer includes a gas pipeline and a fireproof filler arranged around the gas pipeline; the trench structure also includes a heat-conducting connector, which passes through the laying layer and connects the soil at the bottom of the laying layer and the backfill soil layer.
[0005] The gas pipeline laying trench structure described in the utility model is provided with a laying layer and a backfill soil layer. Since the laying layer is filled with fire-proof filler, it is beneficial to the fire prevention of the gas pipeline. However, the continuity of the soil structure and layers is destroyed. The setting of the heat-conducting connector can accelerate the energy flow between the soil and the backfill soil layer, thereby helping to accelerate the recovery of surface vegetation.
[0006] As a preferred solution, the heat-conducting connector is a metal tube, which has good thermal conductivity, high strength and long life.
[0007] As a preferred solution, the metal tube is an aluminum tube, the gas pipeline is a seamless steel tube, and the aluminum tube is connected to the gas pipeline through a conductor. The gas pipeline and the aluminum tube are connected through the conductor to form a primary battery, the aluminum tube serves as a protective electrode, and the gas pipeline serves as a protected metal. When electrochemical corrosion occurs in the gas pipeline, the aluminum tube, as the negative electrode, undergoes an oxidation-reduction reaction and is sacrificed and consumed, and the gas pipeline, as the positive electrode, is protected from corrosion.
[0008] As a preferred solution, the aluminum tube is an aluminum capillary tube. Due to its capillary structure, the aluminum capillary tube can accelerate the flow of materials between backfill soil layers and soil layers, especially the flow of water, thereby accelerating the recovery of surface vegetation.
[0009] As a preferred solution, the metal pipes are located on both sides of the gas pipeline, and the metal pipes on the same side are arranged at equal intervals.
[0010] As a preferred solution, the groove is a trapezoidal groove that is wide at the top and narrow at the bottom. The trapezoidal groove is convenient for laying gas pipelines and installing other equipment.
[0011] As a preferred solution, the fireproof filler is a fireproof mortar, which is a non-combustible material and is heat-insulating and high-temperature resistant. When the external temperature rises sharply or a fire occurs, the fireproof mortar can effectively prevent the external high temperature or fire from endangering the gas pipeline and improve safety during daily operation.
