Embodiment Construction

[0035] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0036] Such as Figure 1-4 As shown, it is a one-time pouring large-diameter steel pipe concrete encapsulation method disclosed by the present invention, comprising steps:

[0037] 1) Pouring of reinforced concrete support 2 and installation of arc-shaped support 3: multiple reinforced concrete supports 2 are poured along the axial direction of the preset steel pipe 1, and the reinforced concrete support 2 is a cuboid, and the lower part of each reinforced concrete support 2 A plurality of lower horizontal bars 100 perpendicular to the axis of the steel pipe are pre-embedded, and a plurality of hollow tubes 21 for piercing the lower longitudinal bars 101 are pre-embedded in the lower part of the reinforced concrete support 2. The hollow tubes are made of PVC pipes. 2 After drying to meet the design requirements, the top surface of the reinforced concrete sup...

Abstract

The invention relates to a one-time encapsulation method of pouring large-diameter steel pipe concrete, which includes pouring of supports and installation of support seats; hoisting of steel pipes; installation of steel bars; installation and reinforcement of side steel formwork; Installation; installation of upper transverse reinforcement and upper longitudinal reinforcement; installation of steel pipe horizontal plug formwork; pouring concrete to design height. The invention can effectively control the displacement caused by the floating of steel pipes in the process of pouring concrete, ensure the construction quality and improve the construction efficiency.

Description

technical field [0001] The invention relates to the technical field of engineering construction, in particular to an encapsulation method for one-time pouring of large-diameter steel pipe concrete. Background technique [0002] For super-large projects of long-distance water transfer across river basins, it is necessary to build storage projects along the line. During normal maintenance of the main canal and supporting projects or when emergencies occur, it is necessary to ensure the water supply safety of the water-receiving cities and improve the water-receiving capacity. The water shortage in the region has been effectively alleviated, the ecological landscape effect has been improved, and a good water environment has been provided for citizens' leisure and entertainment. [0003] Stabilizing the supply of water sources will reduce the exploitation of groundwater in the water-receiving area, and play an important role in alleviating the tension of water resources in the r...
