Example Embodiment

[0056]Example 1

[0057]Such asfigure 1 ,2As shown, it is a bridge active correction device of the present invention adjacent to the foundation pit. Among them, the support structure system of the foundation pit is composed of support 11, the waist 13, the foundation pit shear structure 17, and the local reinforcement module 1. Such asimage 3 ,4As shown, the foundation pit retarding structure 17 is typically composed of a foundation pit enclosure structure 14 and a crown beam 12, and sometimes the crown beam 12 is required. The local reinforcing module 1 consists of a lateral reinforcing steel beam 15 and a vertical reinforcing steel plate 16. The first lateral reinforcing steel beam is disposed between the first support 11 of the foundation pit, and the last two transverse reinforcing steel beams 15 are arranged on the upper and lower surfaces of the waist 13. One side flange 15 of the transverse reinforcing steel beam is fixed by welding, and the other side flange 15 of the lateral r...

[0063]Example 2

[0064]Such asFigure 16 As shown, the main difference from the present embodiment and the first embodiment is that the use scenario is used. In the present embodiment, the main contractor 33 of the foundation pit and the carrier hug 8 exists, by changing the shape of the dispensing beam 21 guaranteed intelligence The jack 23 can effectively apply a load, even when the base pit is formed with the casing 33 of the pedestrian hug 8, the device can still be corrected, and the device can realize the application of various positional relationships of the foundation pit and bridges. Match.

Abstract

The invention discloses a bridge active deviation rectifying device adjacent to a foundation pit and a construction method of the bridge active deviation rectifying device. The bridge active deviation rectifying device comprises a local reinforcing module used for reinforcing a soil retaining structure of the foundation pit, a servo module used for providing deviation rectifying loads, a force transmission module used for transmitting the loads, a bearing platform hoop and a monitoring module used for bridge monitoring. A series of problems of deviation rectification of a bridge structure close to the edge of a foundation pit are solved in a targeted mode, the device can adapt to variables such as the relation between different relative positions and distances between the foundation pit and a bearing platform and the size and shape of the bearing platform, deviation rectification loads can be effectively and evenly transmitted to the bearing platform, and a complete assembly type universalization device is formed; and a brand-new thought is provided for deviation rectification of the bridge adjacent to the foundation pit. In addition, due to the modular design of the device, on-site rapid installation and use can be achieved, and an effective solution is provided for bridge structure safety protection, emergency rescue and the like.

Description

technical field [0001] The invention relates to the technical field of bridge deviation correction, in particular to an active deviation correction device for a bridge adjacent to a foundation pit and a construction method thereof. Background technique [0002] With the progress of urbanization, more and more foundation pit constructions appear around the existing bridges. As for the bridge structure, caps and bridge piles are important components for the bridge to support the structural load on the upper part of the bridge and ensure the normal and safe operation of the bridge. If the deviation is not corrected in time, the bridge will continue to tilt, and even affect the safety of the bridge structure and operation. [0003] Although the existing bridge deviation correction devices can effectively solve bridge structure deviation and safety problems, the general deviation correction devices have a large volume and weight, which has a great impact on road traffic, and the...
