Tower crane foundation in building basement and manufacturing method of tower crane foundation

Abstract

The invention discloses a tower crane foundation in a building basement and a manufacturing method of the tower crane foundation. The tower crane foundation is manufactured into an orthogonal beam slab type reinforced concrete tower crane foundation composed of an orthogonal beam and a slab. During manufacture, a pit of the tower crane foundation is dug in the building basement, and then the orthogonal beam is poured in a traditional mode of pouring reinforced concrete and the slab is poured on the orthogonal beam, and meanwhile, at least one circle of water retaining boards is fixedly inlaid around the slab; base plate surface ribs of basement base plates are embedded according to a traditional mode of pouring the basement base plates, and then the basement base plates are poured; and after the basement base plates are poured, the water retaining boards are inserted into the basement base plates around the slab, so that the orthogonal beam slab type reinforced concrete tower crane foundation is connected with the basement base plates into one. The tower crane foundation has the advantages of fastness, convenience and high efficiency in construction, low construction and operation cost, reliability in performance, safety in operation, convenience in operation and the like.

Problems solved by technology

[0002] Since the reform and opening up, with the rapid development of my country's economic construction and the improvement of construction technology, high-rise buildings have sprung up, and the scale of construction projects has become larger and larger. The construction area of ​​hundreds of thousands, and the area of ​​the basement have also increased accordingly. The transportation of materials during construction is convenient, and it is often necessary to install the tower crane inside the ground building, so that the foundation of the tower crane will conflict with the basement floor, causing inconvenience in construction and causing many problems if the part is not properly handled

Due to the relatively large tower crane foundation in the prior art, it is placed in the basement floor of the building, and often "fights" with the foundation of the floor cap, causing inconvenience in construction

In the prior art, the tower crane foundation is usually set below the basement floor level, and the basement floor where the tower crane foundation is located will be poured with concrete to close the basement floor after the tower crane is removed from the structure (the closed floor will bury the tower crane foundation underground ), if the waterproof treatment is not good at the connection between the basement floor of the post-poured basement and the old floor of the original basement, it will cause water seepage in the floor in the future

And because the basement floor of the span is not closed, the groundwater in this part will often seep up, and the foundation of the tower crane will be soaked, which seriously affects the normal operation of the tower crane and buryes a safety hazard.

In order to solve this problem, it is often used in the prior art to continuously pump water at the base of the tower crane during the entire construction stage of the structure, which not only consumes a lot of pumping shift fees and increases construction costs, but also due to Factors such as drainage and power consumption of water pumps have added new safety hazards

Therefore, the existing method of making tower crane foundation in building basement is still not ideal enough
