Pouring structure of concrete bearing platform and pouring method

Abstract

The invention provides a pouring structure of a concrete bearing platform and a pouring method. The pouring structure comprises a steel reinforcement framework, wherein a plurality of layers of cooling pipes and a plurality of layers of temperature control elements are arranged in the steel reinforcement framework; the temperature control elements are arranged at a half position of the plane structure of the steel reinforcement framework and are used for guiding the temperature control construction of the other half position of the plane structure of the steel reinforcement framework; the steel reinforcement framework forms the concrete bearing platform through concrete pouring; the pouring method comprises the following steps: digging a foundation pit, exploding a pile head, constructing a cushion course, mounting the steel reinforcement framework, mounting the cooling pipes and the temperature control elements on the steel reinforcement framework, and pouring concrete on the steel reinforcement framework twice. The pouring structure of the concrete bearing platform and the pouring method can control temperature crack to ensure the construction quality of concrete.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a pouring structure and a pouring method of a concrete cap. Background technique [0002] During the concrete pouring process of the reinforced skeleton, the following problems often occur: [0003] 1. The volume of concrete components is large, and the heat of hydration is concentrated. It is necessary to strengthen temperature control measures and detection measures to avoid a large number of internal cracks, which will affect the durability of the structure; [0004] 2. The temperature in the construction month is low, the temperature difference between day and night is large, it is windy, and the environment is relatively harsh. It is difficult to guarantee the difference between the internal temperature of the concrete and the ambient temperature, and the risk of cracks in the concrete is relatively high. [0005] In order to avoid cracks inside the steel skelet...

AI Technical Summary

Problems solved by technology

[0006] The object of the present invention is to provide the pouring structure and pouring method of concrete caps to solve the existing problems in the prior art. Due to the large volume of concrete components and the concentrated heat of hydration, it is necessary to strengthen temperature control measures and detection measures to avoid a large number of internal Cracks, thus affecting the durability of the structure; the temperature in the construction month is low, the temperature difference between day and night is large, it is windy, the environment is relatively harsh, the difference between the internal temperature of the concrete and the ambient temperature is difficult to guarantee, and the risk of cracks in the concrete is relatively high.
