Description

Technical Field

[0001] The utility model relates to the technical field of bridge engineering, in particular to a large-diameter pile-wall combination excavation-free anchor foundation pile foundation steel bar processing tire frame. Background Art

[0002] The anchor is the main load-bearing component of the suspension bridge, and plays a decisive role in the overall stability and bearing performance of the suspension bridge. At present, the anchor foundation of large domestic suspension bridges generally uses caisson foundation or underground continuous wall foundation. The construction excavation volume is large and has a great impact on the environment.

[0003] The Xunjiang Bridge project of Cangrong Expressway crosses the waters of Xunjiang River, and the surrounding environmental and water conservation requirements are high. During the construction period, it is necessary to minimize the damage to the surrounding environment and strengthen the protection of the surrounding environment. The project crosses the Xunjiang River, and the north and south banks are managed by different counties. The access roads to the anchors on both sides must pass through local villages. The roads along the river on both sides are under construction, and their construction will cause great interference to the construction of the bridge. Therefore, the anchor foundation of the Xunjiang Bridge of Cangrong Expressway adopts a wall foundation of large-diameter pile foundation + milling groove. The foundation structure is novel, and the excavation of the anchor foundation soil is reduced. It has the characteristics of reducing environmental damage, reducing construction difficulty, reducing project cost, and shortening construction period.

[0004] Through the construction experience summary of the milling trench of the Xunjiang Bridge project of Cangrong Expressway, a large-diameter trenchless trench reinforcement construction and connection method was formed. During the construction of the reinforcement cage, the long-line method was adopted, and the special hoist was used to lift and lower it, and the large-diameter trenchless trench reinforcement cage was lowered with special homemade tools. This method serves as a reference for the subsequent large-diameter pile foundation + milling trench wall foundation milling trench reinforcement construction.

[0005] Then, after the existing general steel bar processing frame is used to tie the steel bar cage in the project, it is very inconvenient to separate the steel bar cage from the steel bar processing frame, and workers are required to split it point by point, which increases the labor intensity of the workers. Utility Model Content

[0006] The utility model aims to provide a large-diameter pile-wall combination excavation-free anchor foundation pile foundation reinforcement processing tire frame to solve the above-mentioned defects caused by the prior art.

[0007] The cam is secured to the bottom of the base and is provided with a plurality of flange adapters, the flange adapters being provided with a plurality of flange adapters, the flange adapters being provided with a plurality of flange adapters, the flange adapters being provided with a plurality of flange adapters and the flange adapters being provided with a plurality of flange adapters.

[0008] Preferably, a positioning pin is inserted at the top end of the side-mounted tube, and a U-shaped positioning groove is provided at the lower end of the connecting tube.

[0009] Preferably, a hand wheel is fixedly connected to the lower end of the side support tube.

[0010] Preferably, a C-shaped handle is welded on the side of the connecting pipe.

[0011] Compared with the prior art, the utility model has the following advantages:

[0012] When the steel cage is tied, first lift the top hanging plate with the help of the handle and quickly separate the top layer of steel bars from the top hanging groove, then use the hand wheel to rotate the side support tube and shorten the exposed length of the side support rod, thereby driving the side mounting tube to deflect outward around the ear plate, and quickly separate the steel bars on the left and right sides from the corresponding side support plates, finally lift the steel cage with the lifting equipment and quickly separate the bottom layer of steel bars from the bottom support plate, avoiding the workers from splitting them point by point and reducing the workers' labor intensity.
