Construction method of corbel reinforcement for gate pier

Abstract

The invention provides a construction method of gate pier corbel reinforcement, which comprises the following steps: 1. Fabricate a reinforcement cage body on a site other than the gate pier, and weld an inner bracket inside the reinforcement cage; 2. Install the poured gate pier concrete for support The outer bracket of the steel cage; 3. Set up the cantilevered scaffolding support device for supporting the bottom mold of the corbel on the poured gate pier concrete; 4. Lift the steel cage as a whole and position it accurately; 5. The steel cage and the gate The other steel structures of the pier body are connected and formed; 6. Remove the inner bracket and outer bracket, and wait for the concrete pouring of the corbel warehouse; through the above steps, the one-time overall prefabrication and hoisting construction of the left and right corbel steel bars of the hydraulic gate pier will be realized. Through the above steps, the hoisting and positioning of the steel cage body can be realized at one time, without the need for secondary welding construction of the steel cage body with the rise of the pier body, avoiding construction interference, improving work efficiency, greatly reducing the workload of high-altitude operations, reducing safety risks, and good economy .

Description

technical field [0001] The invention relates to the field of construction of hydraulic structures, in particular to a method for constructing gate pier corbel reinforcement. Background technique [0002] As an important functional structure of the sluice pier, the corbel of the hydraulic sluice pier has the characteristics of complex design structure, dense steel mesh, many embedded parts, narrow construction space and high construction precision requirements, see Figure 7 . The traditional corbel installation process is to process a single steel bar in a steel bar processing plant according to the design specifications and types, and then hoist it to the high-altitude corbel warehouse. Orientation is not horizontal. The process of direct welding of steel bars on site requires that the heightening and lengthening of steel bars can only be carried out after the condition of the lower part of the pier body is met. Since the fan-shaped steel bars of the corbels, the embedded...

AI Technical Summary

Problems solved by technology

Since the fan-shaped steel bars of the corbel, the embedded parts of the corbel, the distributed steel bars of the gate pier body and the corbel formwork support device are constructed at the same time, the traditional installation process will cause cross-interference in the process

The amount of high-altitude work involved in steel bar welding, bar penetration, and embedded parts construction is huge, the construction process is cumbersome, the construction period is long, the work efficiency is low, and the construction space of the high-altitude pier body is small, and there are also relatively large safety risks
