Abstract
This invention discloses a method for spreading mountain roads with suspension and cantilever structure including the following steps: at the valley side of an original road edge, a place is designed to be placed with concrete template beam, prestressed concrete cantilever beams are inserted into the slopr rook and anchor bar or prestressed anchor rope or balance weight are used as the fixed end of the cantilever and template beam as its outer point of support to spread reinforced concrete precast slabs with the cantilever lower flange of the inverted T type section as the support at the necessary spreading part and protecting fence is set at the road outer string and the road is finished after laying.
Description
The invention belongs to the building structure technology field, relate in particular to a kind of method of widening mountain road with cantilevered structure.
Along with The development in society and economy, the traffic volume increases day by day, and original inferior grade road generally faces the problem of widening transformation.In the prior art, the transformation of widening of mountain road has been continued to use usually in backer's side and cut sloping broadening, banketed by the ditch side or building retaining wall broadening.This method is effective to widening of the milder mountain road of the gradient; But the road to the precipitous location of the gradient is widened, if adopt and cut sloping broadening in backer's side, cut the height that the slope height can reach tens of rice, not only engineering quantity is huge, cause investment to increase severely, and high cut the natural stability that massif has been destroyed on the slope, and stayed the hidden danger that causes large volume landslide or avalanche, also destroyed natural environment significantly; Building retaining wall broadening if adopt by the ditch side, the retaining wall height can be up to tens of rice, also will cause engineering quantity huge and investment is increased severely; Employing is also arranged widening road by the ditch side with the mode of banketing, so then may obviously occupy the river course, change the natural situation in river course, fills embankment side slope bottom also can suffer the erosion of flood in the ditch throughout the year, finally causes roadbed to collapse.
The object of the invention is to provide a kind of both technology simple, quick construction, safe and reliable, economical and practical, does not destroy the method for widening mountain road of the stable and conservation of nature environment of massif again.
Purpose of the present invention realizes with following technical step: A. if the original path edge is the astable backfill that should not do the bearing beam basis, then can adopt the basis of pile foundation as bearing beam by ditch side original road edge set position concreting bearing beam; B. press design pitch prestressed concrete outrigger along road direction, outrigger stretches into the anchorage length of backer's side should be determined according to the requirement of its overturning or slip resistance analysis power, can set up anchor pole or prestress anchorage cable or balance weight at outrigger backer end in case of necessity and strengthen its resistance to capsizing; C. needing widened section at road serves as to support to lay reinforced concrete prefabricated board with outrigger bottom flange, inverted T shape cross section; D. at outer ledge anticollision barrier is installed, and is finished paving, form the road after widening.
Good effect of the present invention is: the road to precipitous location, hillside is widened; form the widened section of road with the overhanging type bridge construction of prefabricated installation; both easy construction was quick; avoided the high potential safety hazard that slope or high embankment etc. may be brought out major landslip, avalanche or roadbed side slope landslide of cutting again; protect the natural ecological environment in mountain area again, had fairly obvious technology, economic benefit and environment protection significance.
Below in conjunction with accompanying drawing enforcement of the present invention is described in further detail:
Fig. 1 is an enforcement structural representation of the present invention
Fig. 2 is the I-I sectional view of Fig. 1
Fig. 3 is the structural plan figure of Fig. 1
Part 1 is a concrete pad beam, part 2 is precast prestressed concrete outriggers, part 3 is precast rc slabs, part 4 is paving, and part 5 is railings, and part 6 is pile foundations, part 7 anchor poles or prestress anchorage cable, part 8 is balance weights of outrigger, and part 9 is excavation side slope faces of original path, and part 10 is embankment or natural slope faces of original path; Mark a is original road width among the figure, the road part of b for widening, and c is the length that outrigger 2 embeds the rock mass part.
The present invention realizes by four road master operations with following technical step:
The first road master operation: at the concrete pad beam 1 of building by ditch side original path edge desired location as the outrigger fulcrum.As this place's ground is the stable side slope with required bearing capacity, can be directly concreting bearing beam 1 thereon; Otherwise, should finish the construction of pile foundation 6 earlier, and concreting bearing beam 1 based on this;
The second road master operation: press design pitch prestressed concrete outrigger 2 along road direction, outrigger 2 is looked geological condition and different in the anchoring of backer's side: when for the stable high quality rock slope, can directly outrigger 2 be embedded rock mass as the anchoring section, embedding rock mass length c should determine according to force request; To the non-prime preferably rock of geological conditions location, anchor pole or prestress anchorage cable 7 anchor point as outrigger 2 can be set, anchor pole or prestress anchorage cable 7 stretch into the degree of depth of below ground and should determine according to force request; Otherwise, can hold cast-in-situ concrete balance weight 8 to strengthen its resistance to capsizing the backer of outrigger 2, the volume of balance weight 8 should calculate according to the overturning or slip resistance analysis stability requirement of outrigger 2 to be determined;
The 3rd road master operation: needing widened section at road serves as to support to lay reinforced concrete prefabricated board 3 with outrigger 2 bottom flanges, inverted T shape cross section;
The 4th road master operation: in the outside that road is widened anticollision barrier 5 is installed, and is finished paving 4, form the road after widening.
