Embodiment Construction

[0042] Examples see Figure 1 to Figure 7 As shown, a superimposed circular water pipe ditch construction positioning support device includes a supporting lower positioning device and an intermediate positioning device. The lower positioning device and the intermediate positioning device are composed of a series of positioning brackets arranged in parallel at intervals. Adjacent positioning brackets are connected as a whole by connecting tie rods 13 .

[0043] For the positioning bracket of the lower positioning device, refer to image 3 , consisting of an upper concave arc support bar 10, a bottom straight bar 11, and an oblique strut 12 between the concave arc support bar 10 and the bottom straight bar 11, the two ends of the oblique support bar 12 are respectively connected to The concave arc support rod 10 is fixedly connected with the straight rod 11. The specification of the straight rod 11 is -80x6, and the total length is 2700mm. The radian of the concave arc-shaped ...

Abstract

The invention discloses a round hole construction locating and supporting device of overlapped circulating pipe ditches and a construction method. The round hole construction locating and supporting device comprises a lower locating device and a middle locating device, which are cooperatively arranged, wherein the lower locating device and the middle locating device are composed of a series of locating brackets arranged at intervals in parallel, and the adjacent locating brackets are connected into a whole through a connecting rod; the locating bracket of the lower locating device is composed of a concave arc-shaped supporting rod at the upper part, a straight rod at the bottom and an inclined supporting rod located between the concave arc-shaped supporting rod and the straight rod at the bottom; the locating bracket of the middle locating device is composed of an upper cambered supporting rod at the upper part, a lower cambered supporting rod and a middle supporting rod, the upper cambered supporting rod is concave-arc-shaped, and the lower cambered supporting rod is convex-arc-shaped. The technical purpose of accurately locating cambered reinforcing steel bars and internal templates in the hole construction of overlapped circulating pipe ditches to improve the hole construction precision of overlapped water inlet pipelines is achieved.

Description

technical field [0001] The invention relates to a positioning device for the construction of a circulating water pipe ditch and a construction method for a round hole of a circulating water pipe ditch during the construction of a nuclear power plant, in particular to a supporting device for the precise positioning of the steel bars and inner molds for the construction of a superimposed circulating water pipe ditch round hole and its construction method. Background technique [0002] Due to the advantages of low fuel costs, low power generation costs, and reduced pollution, nuclear power is favored worldwide. However, due to the high construction costs and high construction requirements of nuclear power plant base stations, there are not many countries that can realize the construction of nuclear power plants. [0003] The nuclear power plant is a non-ordinary reinforced concrete structure, and its construction accuracy and safety requirements are much higher than ordinary r...
