Concrete inside cooling system with cooling water pipes in multi-split arrangement and cooling method thereof

Abstract

The invention relates to the field of engineering building, and discloses a concrete inside cooling system with cooling water pipes in multi-split arrangement. The concrete inside cooling system comprises a concrete soil block, wherein the inside of the concrete block is sequentially divided into a plurality of cooling units in the upstream and downstream directions; a cooling branch pipe is arranged in each cooling unit; a cooling water inlet pipe is also arranged inside the concrete block in the upstream and downstream directions; a water inlet of each cooling branch pipe is connected onto the cooling water inlet pipe; a water outlet of each cooling branch pipe is singly guided out to the outside of the concrete block; and a flow rate control valve is arranged in the water outlet position of each cooling branch pipe. The invention also discloses a cooling method of the concrete inside cooling system with cooling water pipes in multi-split arrangement. The concrete inside cooling system with cooling water pipes in multi-split arrangement and the cooling method of the system have the advantages that the defects of the conventional cooling water pipe arrangement are overcome, so that the temperature reduction amplitude of each part of the concrete is more uniform; the temperature differences and the temperature stress of each part of the concrete can be effectively reduced; andthe temperature crack occurring risk is reduced.

Description

technical field [0001] The invention relates to the field of engineering construction, in particular to a concrete internal cooling system and a cooling method thereof in which cooling water pipes are arranged one by one and multiple. Background technique [0002] Mass concrete plays an important role in the construction of modern hydropower projects. In the field of hydropower, too high internal temperature or uneven distribution of high concrete dams will cause many problems, and become one of the main factors for cracks during the construction of mass concrete. Therefore, artificial cooling measures must be taken during the construction of mass concrete to reduce the maximum temperature, control and adjust the temperature process and distribution of concrete according to actual needs, and control the occurrence of cracks as much as possible to ensure the safety of the dam. [0003] As an effective means of temperature control of concrete dams, water cooling plays an impo...

Problems solved by technology

In this way, in theory, the length and section size of each branch pipe are controlled to be consistent, and the flow distribution of each branch pipe is basically the same; but in the actual construction process, some cooling water pipes are affected by the interference of concrete pouring and vibration, causing the water pipes to bend or Squeeze deformation, and affect the water distribution of the actual water flow process, it is easy to cause uneven water distribution of each branch pipe, resulting in uneven cooling, and improper control may also cause cracks
