Description

Concrete conveying device

Technical Field

Background

With the development of economy, urban construction is more and more perfect, ground building density is higher and higher, and urban construction is also focusing on the development of underground space. The protection of surrounding overground buildings and facilities in the construction period of the underground space is a precondition for influencing the smooth completion of underground space development, and engineers often select a cover-excavation construction as an unconventional construction technical means during construction, so that overground and underground integrated construction is achieved, and the influence on the overground buildings in the development process of the underground space is reduced to the minimum.

In the cover excavation construction, all reinforced concrete structures cannot be poured at one time, some structures which do not affect the integrity of the main frame structure, such as columns, walls, stairs and the like, are reserved, and pouring is performed after the frame structure construction is completed. It is difficult to avoid reserving casting holes in the upper plate of the post-cast structure and Liang Dengwei for later casting, and manual concrete conveying is often adopted in later casting.

The Chinese patent (CN 214871557U name: a concrete cleaning and conveying device for civil engineering) has the effect that concrete can not leak to the ground in the transportation process and further keep the ground clean through the matched arrangement of the concrete baffle plate, the collecting box assembly and the discharging hose, and has the effect that the feed inlet can be automatically closed very conveniently through the matched arrangement of the concrete car cover, the hinge, the concrete baffle plate and the tension spring; however, in the cover excavation construction, the reserved holes cannot be reserved too much due to structural stress, and when the device is used for pouring, the concrete flows into the hose and flows into the reserved holes by gravity for pouring, and the quality problem of holes in the coagulated concrete occurs.
