Earthing backfilling and cathode protection construction method for horizontal propane storage tank
The invention discloses a horizontal storage tank earthing backfill and cathode protection construction method, a backfill area of a horizontal storage tank is located in a closed retaining wall, the total backfill height is higher than a natural terrace on the outer side of the retaining wall, and the whole top surface of the backfill area is a concrete top plate; the method comprises the following steps: firstly, constructing a first-layer ramp, backfilling a backfilling area of a storage tank until the backfilling height of the inner side of a retaining wall is 500-1000mm higher than that of the retaining wall, and constructing a second-layer ramp; after backfilling is carried out till the cathode protection construction elevation is reached, cathode protection work is carried out, and backfilling around the tank body is carried out after cathode protection construction is completed; and backfilling is continued until the preset backfilling height is reached. According to the earthing backfilling and cathode protection construction method for the horizontal propane storage tank, construction of large machines is facilitated, the construction efficiency is improved, the construction cost is low, the construction quality is easy to control, and construction is safe and reliable.
本发明公开了一种卧式储罐覆土回填及阴极保护施工方法，所述卧式储罐的回填区域处于封闭的挡土墙内，回填总高度高于挡土墙外侧自然地坪，回填区域顶面整体是混凝土顶板；先施工第一层坡道，对储罐的回填区域进行回填，回填至挡土墙内侧的回填高度高于挡土墙500mm‑1000mm，施工第二层坡道；回填至达到阴极保护施工标高后，开展阴极保护工作，在阴极保护施工完成后再进行罐体周围的回填；继续回填直至达到预定回填高度。本发明提供的卧式丙烷储罐覆土回填及阴极保护施工方法，便于大型机械施工，提高了施工效率，施工成本低，施工质量易于控制，施工安全可靠。
