Embodiment Construction

[0025] Hereinafter, the present invention will be further described with reference to the accompanying drawings and specific embodiments. It should be noted that, on the premise of no conflict, the embodiments or technical features described below can be arbitrarily combined to form new embodiments. .

[0026] It should be noted that when a component is referred to as being "fixed to" another component, it can be directly on the other component or there may also be a centered component. When a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a co-existence of an intervening component. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a co-existing centered component. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for illustrative purposes only.

Abstract

The invention discloses a pre-tensioning method precast beam tensioning concrete reaction wall which comprises a side jack, a reaction wall body, ear walls, a pull rod, an anchoring vehicle, a plurality of steel strands, a bogie, a vertical jack, a main bogie and a concrete bearing platform foundation, the rear end of the reaction wall body is connected with the two ear walls, one end of each steel strand is fixed to the anchoring vehicle, and the other end of each steel strand is fixed to the pull rod. The vertical jack is fixed to the concrete bearing platform foundation and drives the main bogie to move up and down so as to provide pulling force of the steel strand, and the reaction wall and the lug wall are fixed to the concrete bearing platform foundation. According to the device, through cooperation of the reaction wall, the lug wall, the pull rod, the anchoring vehicle, the steel strands, the bogie and the vertical jack, the vertical jack is driven to conduct tension transmission, the anchoring vehicle is tensioned to meet the tensioning requirement, the device is applied to tensioning construction of a pre-tensioning method precast beam, and the problems that the pre-tensioning force is large, and safety is insufficient are solved.

Description

technical field [0001] The invention relates to the field of reaction walls, in particular to a pre-tensioned beam tensioned concrete reaction wall. Background technique [0002] At present, in the prestressed structure, the pre-tensioned beam has the advantages of simple overall tensioning process, fast construction speed, good durability, less prestress loss, and no stress concentration under the anchor. Compared with the post-tensioned prefabricated beam At present, pre-tensioned precast beams are mainly used for prestressed steel bundles in bridge structures with fewer spans, and the layout is mostly linear. The position of the beam section is set in the form of a broken line, forming a new structure of a broken-line prestressed concrete pre-tensioned beam. [0003] However, the existing prestressed concrete beams used in the construction of the broken line type have the following defects: [0004] The pre-tensioning prestressed overall tensioning process in the projec...
