Embodiment Construction

[0042] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0043] Such as figure 1 As shown, an auxiliary device for preventing settlement of a viaduct according to a preferred embodiment of the present invention includes an auxiliary cap 2 and a lateral limit support 4, the auxiliary cap 2 is arranged on the pile foundation 5 of the viaduct, and is covered on On the outside of the original cap 7 of the viaduct, the pier column 3 of the viaduct passes through the auxiliary cap 2 and is inserted into the original cap 7, so that the lower end of the pier column 3 is more stable and can prevent the settlement of the bridge; the lateral limit support 4 includes a support base 41 and a support frame 42, the support base 41 is located ...

Abstract

The invention relates to the field of urban bridges, and discloses an auxiliary device for preventing a viaduct from settling and a construction method thereof. The auxiliary device has the function of preventing the viaduct from settling, and comprises an auxiliary bearing platform and a lateral limiting supporting part, the auxiliary bearing platform is arranged on a pile foundation of the viaduct, the outer part of an original bearing platform of the viaduct is covered with the auxiliary bearing platform, and pier studs of the viaduct penetrate through the auxiliary bearing platform; the lateral limiting supporting part comprises a supporting base and a supporting frame, the supporting base is arranged on the ground and is located at the outer sides of the pier studs, a base-connecting end of the supporting frame is connected to the supporting base, and a beam-connecting end of the supporting frame is connected to the position in which a cover beam of the viaduct is connected to the pier studs. According to the auxiliary device for preventing the viaduct from settling and the construction method thereof, the outer part of the original bearing platform of the viaduct is covered with the auxiliary bearing platform, thus the lower ends of the pier studs are more stable, and the bridge can be prevented from settling; through the adoption of the lateral limiting supporting part, the bridge can be effectively prevented from laterally deviating, and thus uneven settlement of the bridge is stopped from further deteriorating.

Description

technical field [0001] The invention relates to the field of urban bridges, in particular to an auxiliary device for preventing settlement of viaducts and a construction method thereof. Background technique [0002] The vast majority of urban viaducts mostly adopt the foundation form of pile foundation. However, the normal operation of urban bridges will be affected by many factors, resulting in uneven settlement of bridge foundations. Moreover, when the uneven settlement of the foundation of the urban viaduct needs to be repaired and reinforced, because the distance between the new pile foundation and the pile foundation of the original structure is relatively close, if the old pile foundation and the old cap of the pier column to be reinforced are in poor working condition, There will be greater risks in the construction of drilled piles. In case of accidents such as hole collapse, it will have an inestimable impact on the original structure. Contents of the invention ...
