Embodiment 1

[0040] Such as figure 1 As shown, the bridge is a multi-joint structure, the bridge spans the valley, and expansion joints 2 are arranged between the main girders 1 of each joint to disconnect, and part of the pile foundation is located in the landslide body 6, and the landslide body 6 is affected by rainfall or construction spoil Under the influence of other factors, sliding down along the sliding surface 3 will cause changes in the plane position and elevation of the bridge, and cause cracks in various parts of the lower structure of the bridge, seriously affecting the safety of vehicles on the upper part. The buffer of the seat is not damaged, only the plane position and elevation change. In order to solve the bridge disease and achieve the purpose of saving manpower and material resources quickly and safely, the construction is carried out through the treatment method of the overall deviation disease of the bridge caused by a landslide body in this embodiment. Before the t...

Embodiment 2

[0052] The only difference between this embodiment and Embodiment 1 is that, as figure 2 As shown, in step S2, the anti-slide pile 8 is a rectangular anti-slide pile 8. When the rectangular anti-slide pile 8 is set, the long axis direction of the rectangular anti-slide pile 8 is consistent with the creeping direction of the landslide body 6, and the rectangular anti-slide pile The bottom of 8 is embedded in the rock formation 7 downwards, and all rectangular anti-slide piles 8 form a semi-enclosed structure in the horizontal plane to the part of the bridge located on the landslide body 6;

[0053] Further, in step S2, the anti-slide pile 8 is also provided with a stress monitoring device, the stress monitoring device includes a control chip and a stress monitor electrically connected to the control chip, an early warning device, and a display terminal, and the display terminal uses In order to realize human-computer interaction, by setting and displaying the stress early warn...

Embodiment 3

[0057] The only difference between this embodiment and Embodiment 1 is that, as image 3 As shown, in the step S3, when setting the new pile foundation 10, the technology of manually digging piles is used to form holes;

[0058] In step S4, such as image 3 As shown, when expanding the original cap 13, first excavate the soil around the original cap 13, and then drill holes on the four sides and the bottom of the original cap 13, the drilling depth is not less than 10 times the diameter, the planting bars are arranged at equal intervals in the vertical and horizontal directions, and after the planting bars are completed, the formwork is poured to form the new cap 14, and the axis of the new cap 14 is offset from the original cap 13 The front axes coincide, and the new pile foundation 10 and the new cap 14 are anchored;

[0059] Specifically, the vertical and horizontal spacing of the planting bars is 45cm, and the construction process of planting bars is as follows:

Abstract

The invention discloses a method for treating integral deviation diseases of a bridge caused by a landslide mass, which comprises the following steps of: firstly, transferring and filling part of the landslide mass to a slope toe of a valley in a manner of clearing and deloading to slow down wriggling of the landslide mass; then an anti-sliding pile is arranged, a semi-surrounding structure is formed on the portion, located in the landslide mass, of the bridge to block and stabilize the landslide mass, the stability of a new pile foundation is improved, then the lower structure of the bridge is newly built or reinforced in a targeted mode, and supporting system conversion of a main beam is achieved; finally, the main beam is restored to the initial position before the bridge deviates only by adjusting the elevation and the horizontal position of the main beam, the treatment and repair construction of the whole bridge affected by the landslide mass is completed after the expansion joint is reinstalled, the whole bridge does not need to be dismantled and reconstructed, the whole construction method is simple and efficient, resources and cost are greatly saved, and the problem of long-term influence of the landslide mass on the bridge is fundamentally solved.

Description

technical field [0001] The invention relates to the field of bridge repair and reinforcement engineering. More specifically, the invention relates to a method for treating the overall deviation of bridges caused by landslides. Background technique [0002] In order to ensure the safe operation and reasonable service life of the bridge, the annual detection, monitoring, evaluation, maintenance and reinforcement need to consume a lot of manpower and material resources. my country is a mountainous area, especially in the west, with vertical and horizontal valleys and complex hydrogeological conditions. Various natural disasters, especially landslides, frequently cause bridge damage, which seriously affects the safety of bridge use. Traditional maintenance methods are mainly based on regular maintenance and after-event maintenance, which mainly has the characteristics of simple management and easy implementation, but it is also easy to cause the consequences of insufficient mai...
