Method for implementing hot rolling swirl pool constructional engineering by top-down method

Abstract

The invention relates to a method for constructing a hot rolling swirl pool structure project by the top-down construction method. The specific method comprises the following steps: digging measurement pile foundation holes, making brick protection walls, pouring to for measurement piles, dividing the part of the outer barrel above the trapezoid-shaped bottom of the swirl pool into a plurality of sections with different heights; digging earth from the top to the bottom in sections and taking the earth wall of the dug earth as a bottom die of the outer barrel and a natural earth die of an outside die; supporting and establishing a combination steel die plate inner die on the inner side; pouring concrete together with the measurement piles; conducting the construction for the trapezoid-shaped bottom; pouring an ring-shaped bracket inside a construction joint between sections; and conducting the construction for an inner barrel of the swirl pool, a water absorption tank platform, a pump station platform and a top plate platform. In the invention, the pool outer barrel is constructed from the top to the bottom in sections by the top-down construction method, the ring-shaped bracket is poured inside the construction joint between sections, and the measurement piles are arranged in the poor outer barrel, thereby basically solves the waterproof, settlement and anti-floating problems, utilizing the construction technique and saving cost. In the hot rolling swirl pool constructed through the method of the invention, no settlement or upward-floating phenomenon occurs, no construction joint is generated, and no quality problem of water leakage or water seepage is caused.

Description

technical field

[0001] The invention relates to a construction method of a hot rolling swirl pool structure. Background technique

[0002] The hot-rolling swirl pool is an essential engineering component of the hot-rolling production process line of the steel plant. It uses turbid circulating water to spray water to cool the process equipment. In the flow pool, the impact swirl of water is used in the swirling pool to collect and use the sediments produced by impurities and fermented iron sheets, so that the turbid circulating water can be reused after sedimentation and filtration.

[0003] There are two conventional and traditional methods for the construction of the swirling pool project: the first method is: after a large excavation of earth and rock, construction from the bottom to the top; the second method is: caisson construction method.

[0004] Disadvantages of the first method: the working surface needs to be increased by more than 30 meters, and the excavation of...
