Abstract

The invention discloses an emergency traffic method for a water-destroyed scouring road section of a highway along a river in a mountainous area. The method comprises the steps that a plurality of side-by-side cable-stayed cantilever beam structures are built within a treatment section range after a water-destroyed disaster of the highway along the river in the mountainous area happens; longitudinal beams are built on the cable-stayed cantilever beam structures; the side-by-side cable-stayed cantilever beam structures form an integral anchor frame structure by the longitudinal beams; road slabs are paved on the anchor frame structure; and then emergency traffic is achieved. The method has the benefits that an emergency traffic passage can be built temporarily on the water-destroyed road section of the highway along the river in the mountainous area, for temporary emergency traffic of vehicles, and the efficiency of rescue and relief work is improved.

Description

The highway section of Highway erosion along the river, mountain area emergent passing method

Technical field

The present invention relates to a kind of technology for damaged or destroyed by flood highway section emergent passing, relate in particular to the highway section of Highway erosion along the river, a kind of mountain area.

Background technology

Highway is the great damaged or destroyed by flood type of China's mountain highway always, have the frequency of occurrences high, have a very wide distribution, the fundamental characteristics such as the condition of a disaster is serious, although it is prevented and reduced natural disasters and is subject to the great attention of highway administration department but is never effectively solved, especially over past ten years, under global geology active level aggravation, the frequent on a macro scale background that occurs of extreme meteorological condition, China's western mountainous areas Debris Flow along Highways and mountain torrents the condition of a disaster sharply worsen, and rainy season in every year, highway in China mud-rock flow and mountain flood were lost about 3,000,000,000 yuan.Rough estimates show, by in December, 2012, the western China total mileage of highway is above 1,020,000 kilometers, wherein Sichuan Province is 27.4 ten thousand kilometers, 110,000 kilometers of Chongqing City, 12.5 ten thousand kilometers in Guizhou Province, 20.4 ten thousand kilometers in Yunnan Province, 150,000 kilometers of Xinjiang Uygur autonomous regions, 10.6 ten thousand kilometers in Gansu Province, 5.2 ten thousand kilometers of Tibet autonomous regions of Tibetan.In 1,020,000 total mileage of highways, there is serious Flood disaster hidden danger in more than 40 ten thousand kilometers of 40% highway section meters, a large amount of road surfaces of highway subgrade along the river by whole damaged or destroyed by flood after, limited the emergency disaster relief of the condition of a disaster.

So far, China is preventing and treating aspect the Flood disaster of highway, substantially rest on after the calamity that engineering is recovered, the reconstruction aspect, lack emergent Treatment Methods and required corresponding special equipment, cause the disconnected road of a large amount of highways after the ground generation heavy showers such as Wenchuan, Sichuan Province's in July, 2010, Mao County, breakdown lorry, equipment can not enter the disaster area, cause the calamity economic loss and expand to more than 500,000,000 yuan by about 200,000,000 yuan.

Summary of the invention

For the problem in the background technology, the present invention proposes the highway section of Highway erosion along the river, a kind of mountain area emergent passing method, the method step is as follows: 1) after the Flood disaster of highway generation along the river of mountain area, carry out field investigation, determine to need to lay the punishment section of emergent passing road;

2) in punishment section scope, along supernatant riverbank bank base, a plurality of carrying piers are set, carrying pier upper surface keeps level, and the carrying pier is reinforced concrete structure or the bar stone masonry structure of cast in situs;

3) in punishment section scope, on the massif of carrying pier top a plurality of anchor poles are set, the quantity of anchor pole and position are corresponding one by one with the carrying pier; The anchor pole outer end is fixedly connected with the inner of steel cable; A plurality of anchor poles are corresponding one by one with many steel cables respectively;

4) crossbeam the inner is placed on carrying pier top, a plurality of carrying piers are corresponding one by one with many crossbeams respectively;

5) at the middle part of crossbeam upper side the steel cable buttress is set, a plurality of crossbeams are corresponding one by one with a plurality of steel cable buttresses respectively; Described steel cable buttress is frame construction, and the endoporus of a plurality of steel cable buttresses aligns setting;

6) the crossbeam outer end is held up the axially maintenance level of crossbeam that makes, and the inner end face of crossbeam keeps in touch with the massif of carrying pier inboard, then steel cable outer end and crossbeam outer end are fixed, and steel cable middle part contacts (steel cable buttress jack-up one segment distance that steel cable can be made progress with steel cable buttress top, increase the inner space that anchor draws frame construction, improve the transverse width of emergent passing passage, simultaneously, the steel cable buttress also can make the active force of steel cable outer end and the angle of vertical direction reduce, to reduce the suffered axial stress in crossbeam outer end, make the pulling force of steel cable more effectively be used for the gravity of supporting structure and vehicle); The structure that crossbeam, carrying pier and steel cable three form forms the cable-stayed type cantilever beam structures;

7) lay interior beam at crossbeam carrying Dun Shangfangweizhichu, interior beam is fixedly connected with many crossbeams respectively;

8) lay jack stringer at crossbeam, jack stringer is fixedly connected with many crossbeams respectively, and jack stringer runs through the endoporus of a plurality of steel cable buttresses; The structure that is comprised of crossbeam, steel cable, interior beam and jack stringer forms anchor and draws frame construction;

9) lay road slab at crossbeam, interior beam and jack stringer, the emergent passing road is built and is finished;

Wherein, described crossbeam is the strip reinforced concrete structure body that presets; Described interior beam is angle steel or i iron; Described jack stringer is angle steel or i iron.

Crossbeam among the present invention, steel cable, steel cable buttress, interior beam and jack stringer are preset piece, directly install during use to get final product, and can dismantle for subsequent use after emergent passing finishes; After adopting the present invention program, when occurring need to be in the mountain area when situation of emergent passing is implemented in the Highway highway section along the river, build the emergent passing road by the present invention program, in 8-10 hour, can build 2 to 3 kilometers long emergent passing roads, pass through for the load-carrying vehicle below 5 tons, make disaster relief supplies transport as early as possible the disaster area to, after rescue and relief work finishes, the emergent passing passage is removed, again permanent disposal is done in the damage highway section.

In order further to improve the stability of structure, the present invention has also done following improvement: described anchor pole adopts the self-anchored emergency anchor rod of ZL201010242145.4 Chinese patent.

Useful technique effect of the present invention is: in the short time, can be in the mountain area along the river the Highway highway section build the emergent passing passage temporarily, for the interim emergent passing of vehicle, improve the efficient of rescue and relief work.
