Layout and hoisting process of a ground-to-wall reinforcement cage production line

Abstract

The invention discloses a production line arrangement and hoisting process of a ground-connected wall reinforcement cage, including step S2: layout and construction of a reinforcement processing plant and a reinforcement cage production line. The cage production line is arranged at one corner of the ground connection wall construction site at right angles, and the area formed by the vertical extension of the reinforcement cage production line boundary to the ground connection wall construction site is the crawler crane operation area. The present invention optimizes the layout of the reinforcement cage production line and makes full use of the site around the ground connection wall, so that the process is not limited by whether the surrounding terrain is flat or not, allowing the reinforcement cage production area and the reinforcement cage hoisting operation area to have a large terrain height difference, Thus, the cost of on-site earthwork transportation is greatly reduced, and the pollution caused by dust and spoils is reduced, which is conducive to the requirements of environmental protection; by improving the hoisting process, the section division of the reinforcement cage of the ground-connected wall is reduced, and the transportation distance is shortened. Greatly improve efficacy.

Description

technical field [0001] The invention relates to the technical field of ground connection wall construction techniques. More specifically, the present invention relates to a production line arrangement and hoisting process of a ground-connected wall reinforcement cage. Background technique [0002] At present, the production line of ground-connected wall steel cages is generally arranged near the steel bar processing plant, such as figure 1 As shown, since the ground connection wall construction is generally divided into the ground connection wall phase I groove 1 and the ground connection wall phase II groove 2, the plane dimensions of the two are different, and the production line is divided into the I phase groove and the II groove production line. The number of production lines Combined with the construction period of the ground connection wall, the number of groove sections and the processing efficiency of the production line, it is determined comprehensively. In order...

Problems solved by technology

Due to the heavy weight of the reinforcement cage (currently the heaviest exceeds 100t) and long segments (currently the longest exceeds 80m), in order to ensure the smooth transportation of the reinforcement cage to the site, it is necessary to load the reinforcement cage according to the rating of the flatbed transport vehicle. The load is divided into several sections and transported to the site in bulk and then assembled section by section. The flatbed truck is long and has poor maneuverability. outside the wall), the safety risk is high; traditional steel processing plants are generally arranged in areas with flat terrain and convenient transportation. Arranging along the track of the gantry crane is not conducive to the flexible arrangement of the production line. Since the reinforcement cage needs to be constructed according to the long-line method, the production line of multiple reinforcement cages arranged in this way will be relatively long, which greatly increases the transport distance of the reinforcement cage.

[0004] For the situation where the terrain near the ground connection wall is flat and the traffic around the ground connection wall is convenient, it is feasible to adopt this traditional production line layout scheme. The number of connectors (straight threaded sleeves) during joint connection is also not conducive to the control of the accuracy of the steel cage during hoisting and lengthening, which greatly reduces the efficiency of hoisting and lowering, increases costs, and prolongs the construction period.
