A construction device for producing super-long concrete structures

Abstract

The invention discloses a construction device for producing super-long concrete structures, which includes a mixing box, and is characterized in that: the mixing box includes a mixing box shell, and a feeding port is arranged above the mixing box shell, and the stirring box shell There is a diverter valve directly in front, and the direct front of the diverter valve is connected to an external water pipe. An antifreeze addition box is installed on one side of the mixing box shell, and a negative pressure valve is installed on the side of the antifreeze addition box close to the mixing box shell. A gas pipeline is arranged between the antifreeze addition box and the diverter valve, and a high water-reducing agent addition box is arranged on the other side of the stirring box shell, and the high water-reducing agent addition box is close to the stirring box shell One side is provided with an overpressure valve, the gas transmission pipeline 2 is provided between the high water-reducing agent addition box and the diverter valve, and the water inlet pipeline 1 is arranged above the diverter valve. The present invention has a wide range of applicable environments and high quality high feature.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a construction device for producing super-long concrete structures. Background technique [0002] With the rapid development of my country's construction industry, super-long concrete structures have been widely used in construction engineering, and occupy an important position in modern engineering construction. Concrete mixing devices are an important part of the construction equipment for producing super-long concrete structures. Concrete mixing device is a machine that mixes cement, sand and gravel aggregates and water and mixes them into concrete mixture. It is mainly composed of mixing drum, feeding and unloading mechanism, water supply system, prime mover, transmission mechanism, frame and supporting device. The concrete mixing device includes a power mechanism connected to a transmission mechanism through a shaft and a drum driven by the transmission mechanism. A ring ...

Problems solved by technology

Usually, due to the high temperature in summer, the cement hydration reaction is accelerated, the concrete is set faster, and the construction operation time is shortened. Large, especially when the temperature is below zero, it will have a certain impact on the condensation and strength of the concrete, which will eventually lead to poor project quality and fail to meet the design requirements
