Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy and hydropower construction, in particular to a large-diameter pile-connected wall reinforcement cage. Background Art

[0002] With the rapid development of society, urban electricity consumption has increased significantly, and accelerating the construction of power stations has become a top priority. With the gradual increase in the construction of power stations, there are often multiple cascade power stations in a river basin. The downstream water is basically regulated by the upstream cascade power stations. Its characteristics are rapid head changes and high flow rate, which will cause great safety hazards to existing buildings with poor geological conditions on both sides of the river. In order to ensure the safety of existing buildings on both sides of the river, anti-collision pile wall protection is designed to cope with the impact of water flow on them. The anti-collision piles have a larger diameter and a deeper depth, especially 30 to 40 meters are more common. Generally, ordinary steel plates are used to make longitudinal steel bar positioning jigs according to 1 / 3 of the radius of the steel cage. The cut main bars are placed in the steel bar positioning grooves of the jigs according to the length configuration and adjusted and aligned. After 1 / 3 of the surface is installed, a crane is used to roll it, and then the above steps are repeated to complete the remaining parts. The production process requires the crane to cooperate for multiple times to flip the steel cage, which is time-consuming and labor-intensive, inefficient, and easily causes deformation of the steel cage. Conventional pile foundation steel cages are generally round, which cannot fit well with the subsequent wall construction, and can easily cause penetration between the pile wall, and cannot completely protect the existing buildings.

[0003] Therefore, it is necessary to develop a large-diameter pile-connected wall reinforcement cage to solve the above problems. Utility Model Content
