Description

Pier stud protecting device

Technical Field

The utility model relates to the technical field of bridge engineering, in particular to a protective device for an abutment.

Background

For bridge pier, the main failure mode of bridge pier is wear failure, because river water flow is turbulent, and not only sediment is entrained in the water flow, but also stones with certain particle size can be entrained, and the sand and stone continuously collide and rub with pier concrete under the action of the water flow, so that the bridge pier is abraded and failed under the action of long time.

In order to improve durability of the bridge pier, an effective anti-abrasion and impact treatment is required to be performed on the bridge pier to ensure service life of the bridge pier, and common bridge pier protection measures include: (1) the cross section size of the bridge pier is enlarged, (2) the stone throwing protection and (3) the anti-collision protection are carried out. For the protection measure (1), for the newly-built bridge pier column, the cross section size of the underwater part of the pier is properly increased so as to achieve the effect of preventing water erosion and stone from striking the pier, and the common method is as follows: firstly, manufacturing a pier pile casing, sleeving the pier pile casing above a pile foundation before pouring to form a pier, then suspending the pier pile casing by using hoisting equipment, then performing pier pouring construction, after the pier pouring is completed, putting down the pier pile casing, and then filling the gap between the pier pile casing and the pier with concrete to finally form an integrated structure; for the built bridge, the bridge is generally realized by a reinforced concrete sleeve hoop reinforcement mode, and the common method is as follows: drilling holes on piers, tables or pile foundations, arranging anchor rods, arranging reinforcing steel meshes or steel wire meshes, and pouring concrete to form hoops so as to strengthen, wherein the pier formed by the method is low in protection level, and the problems of troublesome construction and high difficulty exist. For the safeguard measure (2), the erosion force of water is born by the barrier formed by the riprap in the water, so that the bridge pier is protected, the protection strength formed by the method has poor stability, the engineering quantity is large, the construction period is long, and the original water channel is easily damaged, so that the method is less adopted. For the safeguard measure (3), the device similar to the device for preventing the ship from striking the bridge pier is arranged, so that the bridge pier is protected from being struck by the barren rock, but the mode has high manufacturing cost and large engineering quantity, and is difficult to popularize and apply.
