Embodiment

[0061] see figure 1 , the present invention discloses a multi-cycle real-time temperature-controlled construction technology for continuous pouring of super-large-volume concrete at one time. The water storage transfer pool built by masonry at the construction site; the inner-surface circulation system is formed by pipelines between the circulating pipe network and the water storage and maintenance pool; the surface-outer circulation system is formed by pipelines between the water storage and maintenance pool and the water storage transfer pool ; The internal-external circulation system is formed by pipelines between the circulation pipe network and the water storage transfer pool; the three circulation systems are controlled by the temperature real-time monitoring system to work together to control the real-time temperature of super-large-volume concrete construction.

[0062] Specific steps include:

[0063] Before construction, it is first necessary to calculate the maxim...

Embodiment 1

[0273] Wuhu Bozhuang Spring Blossom Phase V new construction project

[0274] The project is located at Weiqi Road, Wushi Road, Wuhu City, Anhui Province. The frame-shear structure consists of 1 floor underground and 28 floors above the ground, with a total construction area of ​​98,630m2 2 . The foundation floor is composed of main building rafts (H=3800mm) and podium rafts (H=1700mm), and the underground building area is 30099m 2 , is a super-large volume concrete floor. The base plate pouring construction is in the high temperature period in summer from July to August (the average daytime temperature is above 35 degrees).

[0275] The project adopts this technology, and the interior of the raft foundation is preset in groups according to the circulating pipe network, the surface of the raft foundation is stored and maintained, and the precipitation recharge and rainwater collection system on the construction site are adopted. The combined dual-control monitoring method...

[0277] Wuhu Shimao Riverside Garden 4-1# plot characteristic commercial street project

[0278] The project is located on Beijing West Road, Wuhu City, Anhui Province, with a total construction area of ​​78463m 2 , one basement floor, with an underground building area of ​​about 21,230m 2 , the thickness of the basement floor is 800mm, the thickness of the cap is mainly 2200mm and 2600mm, and the maximum thickness of the core tube foundation concrete is 5300mm. The concrete pouring of the basement floor was at the end of July, which is midsummer and the average daily temperature is above 30°C. This project applies this technology, and the circulating pipe network is preset in groups in the raft foundation. The internal circulation water and the surface water storage and maintenance water of the raft foundation come from the groundwater of precipitation, as well as the precipitation recharge and rainwater collection system on the construction site. The dual-control monitoring...

Abstract

The invention discloses extra-huge-volume concrete once continuous pouring multi-cycle real-time temperature control construction technology. Flow and flow rate of circulating water is automatically regulated by a concrete internal and external temperature real-time monitoring system. Hydration heat inside concrete is gradually reduced to balance the inside and outside temperature difference of the concrete, effectively prevent temperature difference stress inside and outside the concrete from generating a crack, and ensure that construction quality of "extra-huge-volume concrete" meets design and specification requirements. The extra-huge-volume concrete one-time continuous pouring multi-cycle real-time temperature control construction technology has the advantages of saving a lot of water resources, achieving green construction, and conforming to national energy saving and environmental protection policy orientation due to the fact that three communicated circulating water systems including water in a circulating pipe network, water in an entire storage thermal insulation maintenance pool of a base plate and recharge water come from a foundation pit rainfall and site rainwater collection system.

Description

technical field [0001] The invention relates to a concrete construction method, in particular to a super-large-volume concrete one-time continuous pouring multi-cycle real-time temperature control construction technology. Background technique [0002] At present, my country's engineering construction is developing rapidly, high-rise and super high-rise buildings are increasing day by day, and the application of mass concrete is becoming more and more extensive. Article 2.1.1 of "Code for Construction of Mass Concrete" (GB50496-2009) (hereinafter referred to as "the Code") and Article 2.1.10 of "Specification for Design of Ordinary Concrete Mix Proportion" JGJ5 5 - 2 0 0 0 apply to mass concrete Described as: a large volume of concrete whose minimum geometric dimension of the concrete structure is not less than 1m, or concrete that is expected to cause harmful cracks due to temperature changes and shrinkage caused by the hydration of the cementitious material in the concrete...
