Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, but these embodiments should not be construed as limiting the present invention.

[0022] see figure 1 , the concrete production lifting method of the present invention, comprises the steps:

[0023] Step 1. In the mixing building, there are two trays and the mixing capacity is 4.8m 3 Self-falling double-cone mixer for mixing concrete;

[0024] Step 2: Use a single tank to lift up to 9.6m 3 The concrete is lifted by a cable crane, and three buffer tires each weighing 20kg are arranged on the hanging tank of the cable crane. The hoisting length is continuously reduced, specifically, the hoisting length of a single steel wire rope is reduced by 50m for every 50m rise of the dam body.

[0025] It can be seen from the technical scheme of the present invention that in order to achieve the purpose of improving the single-tank lifting capacity of t...

Abstract

The invention discloses a hoisting method for concrete production. The hoisting method for concrete production comprises the following steps that 1 a self-falling-type double-cone mixer is adopted in a mixing plant for mixing concrete, wherein the self-falling-type double-cone mixer is provided with two disks and the mixing capacity of the self-falling-type double-cone mixer is 4.8 m<3> / disk; 2 a cable crane with the single-tank hoisting capacity being 9.6 m<3> is adopted to hoist concrete. The hoisting method for concrete production has the advantages of being high in hoisting capacity, shortening the construction period, improving concrete pouring quality and being economic and safe and can be widely applied to the field of concrete construction of dams.

Description

technical field [0001] The invention relates to dam concrete construction technology, in particular to a concrete production lifting method. Background technique [0002] It has been decades since the first cable crane was installed and used in Tuoxi Hydropower Station in the early 1960s, and the use of cable cranes in dam projects has never stopped. At present, domestic cable cranes are developing in the direction of large span, high speed and large lifting capacity. The maximum span of the cable machine, the lift of the hook, the lifting speed of the hook, the lateral speed of the trolley, and the lifting capacity {10t(3m 3 concrete hanging tank), 20t (6m 3 concrete hanging tank) to 30t (9m 3 Concrete hanging tank)} and other main technical parameters have been greatly improved. At present, the hoisting capacity of the cable crane hoisting tanks used in domestic large-scale hydropower projects is 9m 3 , people prejudicially believe that if it increases to 9m 3 Above,...
