Embodiment Construction

[0016] Embodiments of the invention:

[0017] After the top plate of the reinforced concrete foundation is poured, pounded, and dried, a layer of asphalt cold base oil is first applied on it, and then a layer of asphalt thinner mastic is applied. After it is dry, the asphalt mortar cushion is poured.

[0018] Asphalt mortar is composed of asphalt, powder, asbestos and sand. The weight ratio of each component is: 14.5% asphalt, 14.5% powder, 0.9% asbestos, and 70.1% sand.

[0019] Asphalt uses 10 # Construction petroleum asphalt, softening point 90°C.

[0020] The powder and sand are made of alkali-resistant stones such as limestone and dolomite, and the firmness index of the sand is not less than 93%-98%.

[0021] The production of poured asphalt mortar is to mix the powder and sand preheated to 140°C evenly, then gradually add the asphalt boiled to 210°C, and keep stirring until all the powder and sand are covered with asphalt, and mix until the temperature is 200°C.

Abstract

The invention discloses a method for leading to a reinforced concrete foundation top slab of a steel tank to receive stress evenly. After the reinforced concrete foundation top slab undergoes casting, screeding and drying, a layer of asphaltic base oil is coated on the slab and then a layer of thin asphalt grout is coated, and finally asphalt mortar is paved, and then the coated top slab is compressed with a flat-plate vibrator to form a soft cushion. Compared with the prior art, the method has the advantages of naturally regulating and balancing, transforming the zigzag type partial concentration stress into the evenly distributed load and passing the load to the lower foundation, greatly increasing the degree of safety of the foundation structure, effectively preventing caustic corrosion and prolonging the service life of the equipment, etc.

Description

Technical field: [0001] The invention relates to a method for uniform stress on the top plate of a reinforced concrete foundation, in particular to a method for uniform stress on the top plate of a steel tank foundation used in alumina production. Background technique: [0002] Alumina production is an alkaline leaching process, and there are many steel tanks with large volume and heavy quality. For example, the decomposition tank has a diameter of 14 meters and a height of more than 30 meters. The bottom plate of the steel tank is welded with lap-jointed strips. The total weight of more than 6,000 tons of materials is transmitted to the lower foundation through this zigzag bottom plate. And prior art is to adopt fine stone concrete rigid cushion, and it is difficult for leveling, is difficult for leveling and makes reinforced concrete foundation top plate stressed unevenly, and local stress concentrates, and has caused certain potential safety hazard.
