Problems solved by technology

At present, the main way to overcome road debris flow at home and abroad is to try to detour (change the road), which will undoubtedly affect the efficiency of road transportation
In terms of technical means to overcome road debris flow, construction machinery is generally used to push, dig, and remove debris on the road after the debris flow stops, but there is basically no effective means to ensure road traffic during the occurrence and continuation of the debris flow
Another way is to cut off the source of debris flow other than the road, but this method generally requires a huge amount of work and takes a long time, making it difficult to restore road traffic in a short time

Embodiment Construction

[0013] exist figure 1 Among them, the foldable bridge foot system (2) is stretched and unfolded along the route direction, and then set on the road surface; the bridge deck (1) is laid on it to form a bridge for overcoming mudslides.

[0014] exist figure 2 Among them, after the slope-type folding bridge foot system (2) is stretched along the route direction, it is set on the road surface; the bridge deck (1) is laid on it to form the transition section of the bridge to overcome debris flow; the transition The section and the standard section of the bridge are used together to facilitate the vehicle to get on and off the bridge.

[0015] exist image 3 Among them, for a section of debris flow bridge that has been laid, horizontal fixed piles (6) and vertical fixed piles (7) can be used, and ropes (8) are used to fix the section of the bridge to prevent the bridge from being washed away by debris flow.

Abstract

The invention discloses a bridge capable of overcoming road debris flows. The bridge comprises folding type bridge pier systems and bridge decks. Inner connection pieces of each folding type bridge pier are hinged and can mutually rotate in the horizontal plane or a vertical plane to realize stretching and folding of the bridge pier system. During transportation, the bridge pier systems are put in a carriage after being folded. During paving, the bridge pier systems are erected along road direction at two ends of road sections affected by the road debris flows, the bridge pier systems are spread on the pavement after two ends are stretched by machines, vehicles or manpower and are subjected to necessary anchoring, and then bridge decks are spread on the upper surfaces of the bridge piers one by one to form the bridge capable of overcoming the road debris flows.

Description

1. Technical field [0001] The invention relates to a bridge capable of overcoming debris flows encountered on roads. 2. Background technology [0002] Debris flow is a very common type of natural disaster. When the road encounters a debris flow, its hazards are mainly reflected in the fact that the debris flow has a relatively large impact force, which can damage the roadbed, road surface, road structures and traffic, causing casualties. Especially when highway bridges collapse suddenly due to the action of mudslides, the consequences will be disastrous. The losses caused by mudslides in our country amount to hundreds of millions to billions of dollars every year, especially roads in mountainous areas are often damaged by mudslides. At present, the main method of overcoming road debris flow at home and abroad is to try to detour (change the road and advance), which will undoubtedly affect the efficiency of road transportation. In terms of technical means to overcome road d...
