Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a bridge cable tower concrete placing device. Background Art

[0002] At present, there are more and more special bridges such as long-span cable-stayed bridges and suspension bridges across the country, and the design of cable towers is getting higher and higher, which makes concrete pouring more and more difficult and makes it difficult to ensure the construction quality. Concrete pouring has always been an important part of the entire project construction. The physical quality of the concrete structure directly determines the service life of the entire project. The method of concrete pouring is particularly important. Under the existing construction technology conditions, the concrete of bridge cable towers is generally poured by pumping concrete at a single point. Although the concrete pouring task is completed, it is difficult to ensure the physical quality of the concrete during construction. The main problems that need to be solved urgently are as follows: ① During the construction of most high-rise structures, due to the limited height of the sky pump, it is necessary to pre-embed the surface of the cable tower and pump it into the mold for pouring; because the discharge port of the cable tower is fixed, it is impossible to achieve symmetrical, layered, and continuous pouring construction technology, and it is difficult to ensure the construction quality; ② The cross-sectional size of the cable tower is small, and the working platform is usually erected in the form of installing embedded parts and the platform space is small. Traditional pumping The concrete pouring process requires the assistance of multiple people to complete the construction, which has the following two disadvantages: First, there are many people on the working platform, the embedded parts bear a large load, are prone to instability, and have a high safety risk; second, during the construction of the traditional process, a large amount of manpower is required to shovel the concrete to ensure the continuous flow of concrete, which is not economical; ③ Traditional concrete pouring is a single-point distribution process. Due to the dense structural steel bars, it is difficult for concrete to flow by itself. It relies on the vibration of the vibrator to flow, and aggregate separation or segregation is common, resulting in a series of serious consequences such as reduced concrete strength at the construction joint, reduced concrete impermeability and frost resistance, and easy cracking and deformation.

[0003] Therefore, in order to change the traditional construction method of high-rise structure concrete, improve the quality of concrete pouring, implement the continuous, layered and symmetrical concrete pouring construction process, and eliminate the separation and segregation of concrete aggregates, it is necessary to propose a bridge pylon concrete placing device.
