Abstract

The invention discloses a protection device of a high-pressure gas pipeline. The protection device of the high-pressure gas pipeline comprises first supporting units located on the two sides of the high-pressure gas pipeline. Second supporting units are arranged outside the first supporting units. Each first supporting unit comprises two inner steel plate pile sets. Each inner steel plate pile set comprises a plurality of first steel plate piles arranged in parallel. The two inner steel plate pile sets of each first supporting unit are connected through an inner support. Each second supporting unit comprises two outer steel plate pile sets. Each outer steel plate pile set comprises a plurality of second steel plate piles arranged in parallel. The second steel plate piles of each second supporting unit are connected through a kidney-shaped beam. The two outer steel plate pile sets of each second supporting unit are connected through a top beam. The invention further provides a protection method of the high-pressure gas pipeline. The protection device is simple in structure, convenient to install and low in installation cost. The protection method is simple, few equipment is adopted in the method, and few communal facilities are occupied.

Description

technical field [0001] The invention relates to the field of gas pipeline protection construction, in particular to a protection device and a protection method for a high-pressure gas pipeline. Background technique [0002] With the acceleration of urban construction, a large number of subways, public buildings, and municipal roads and bridges have been implemented one after another. The implementation of these projects has played a huge role in improving the appearance of the city, making it easier for citizens to travel, and enhancing the happiness of citizens. However, during the implementation of these projects, the problem of high-pressure gas pipelines under the foundation is often encountered. High-pressure gas pipelines are sensitive to changes in the surrounding geology, and a little carelessness will cause safety accidents. For the problems encountered in the construction of high-pressure gas pipelines, the measures of relocation and in-situ protection are general...
