Problems solved by technology

(3) When the above-ground measures pass through the forest area, such as thermal piles and other overhead measures, when a fire occurs, it will seriously threaten the safe operation of the pipeline
At the same time, the above-ground measures will face a series of problems such as artificial damage to pipelines and support measures and oil theft.
(4) When the pipeline is buried, it is necessary to build a maintenance channel for regular inspection and maintenance of the pipeline. The construction of the maintenance channel further aggravates the damage to the ecological environment and permafrost wetland in the pipeline construction area

Embodiment Construction

[0017] The technical solution of the present invention will be described in more detail below in conjunction with the accompanying drawings.

[0018] Such as figure 1 As shown, the cooling structure of a through-spread block gravel pipe embankment provided in this embodiment is to fill the pipe embankment above the natural permafrost ground, and the pipe embankment is composed of pipe embankment filling layer 2, fine sand cushion layer from top to bottom. 4 and block stone layer 5, the pipeline is laid in the filling soil layer of the pipe embankment, the outer surface of the pipe is provided with an insulation layer, the section shape of the pipe embankment is trapezoidal, the height of the pipe embankment is 2.1-2.6m, and the slope is 1:1.5, wherein the crushed stone layer 5 is 0.5-1.0m thick, the fine sand cushion is 0.3m thick, the silt layer is 1.3-1.8m thick, and the block stone layer particle size is controlled between 12-30cm. The lower part of the embankment consists...

Abstract

The invention relates to an overground laying type block rubble pipe embankment cooling structure. The overground laying type block rubble pipe embankment cooling structure involves a frozen soil ground and a pipeline, a block stone layer, a fine sand cushion layer and a pipe embankment soil filling layer are sequentially arranged above the frozen soil ground from bottom to top, the pipeline is laid in the pipe embankment soil filling layer, a heat preservation layer is arranged on the outer surface of the pipeline, and the section of the whole body formed by the block stone layer, the fine sand cushion layer and the pipe embankment soil filling layer is trapezoidal. According to the provided overground laying type block rubble pipe embankment cooling structure, the situation that heavy excavation of a pipe ditch is required during laying of a pipeline engineering is avoided, the ecological environment of frozen soil and wetland is protected, and the environment protection principle isachieved.

Description

technical field [0001] The invention relates to a through-pavement block gravel pipe embankment cooling structure, which is suitable for the technical occasion of safe operation of pipelines in permafrost environment. Background technique [0002] Since human beings have carried out engineering practice in permafrost regions, they have encountered various engineering problems, among which frost heaving and thawing settlement are one of the most special and serious problems. The construction of Qinghai-Tibet Railway and Qinghai-Tibet Highway has accumulated a lot of engineering experience for similar projects. Engineering structures such as highways, railways, bridges, pipelines, etc. have different structural forms, and the methods to solve the problems of frost heaving and thawing settlement are also quite different. [0003] As a special linear engineering, the pipeline will cause warping and deformation if uneven frost heave occurs. When melting and settlement occur, if...
