Round coal yard barricade of concrete pilaster of steel plate wall

Abstract

The invention discloses a round coal yard barricade of a concrete pilaster of a steel plate wall. The round coal yard barricade at least consists of reinforced concrete support pilasters and a side wall of steel plates and steel beams fixed on the support pilaster, wherein the support pilasters are uniformly annularly distributed; the steel beams are annularly fixed on all support pilaster, and the annularly arranged steel beams are connected with steel plates which are annularly arranged; the section of the support pilaster is made into a variable-section trapezoidal section with a small top and a big bottom; the annularly arranged steel plates are connected to the annularly arranged steel beams by intermittent welding; an embedded parts are embedded on the support pilasters; and the annularly arranged steel beams are fixedly connected on the support pilasters through the embedded part. The round coal yard barricade disclosed by the invention has a simple structure, is convenient to use and mount, saves material, reduces the use cost and prolongs the service life and the like.

Description

technical field [0001] The invention relates to a retaining wall structure for a circular closed coal yard of a novel thermal power plant, and belongs to the technical field of civil structures of power plants. Background technique [0002] The traditional circular coal yard retaining wall structure has the following types: [0003] 1 Reinforced concrete separated retaining wall with pilasters and temperature joints; [0004] 2 Reinforced concrete integral seamless ring plate retaining wall without pilasters; [0005] 3 Reinforced concrete integral seamless retaining wall with pilasters; [0006] 4 Reinforced concrete integral seamless retaining wall with pilasters and ring beams; [0007] The calculation of the traditional separated retaining wall is simple, but the material is wasteful. The calculation of the traditional integral retaining wall is complicated, especially the complex temperature effect, which is difficult to accurately consider; the reinforcement of the...

[0007] The calculation of the traditional separated retaining wall is simple, but the material is wasteful

The calculation of the traditional integral retaining wall is complicated, especially the complex temperature effect, which is difficult to accurately consider; the reinforcement of the retaining wall is controlled by the crack caused by the temperature effect, and the stress of the steel bar is 160N / mm 2 Not only the actual steel consumption is huge, but also a potential safety risk
