Abstract
The utility model relates to a ribbed-arch multi-arch tunnel, which comprises a side dark-cave tunnel and a middle separation wall as well as a ribbed-arch open cut tunnel, wherein the side with small burial depth landform of the ribbed-arch open cut tunnel is of a dark cave part, the other side is of a ribbed-arch open cut part consists of two or more ribbed arch, and the distance between two adjacent ribbed arch is 4 to 8m; the top part at the adjacency of the dark-cave part and the ribbed-arch open cut tunnel along the length direction of the ribbed-arch open cut tunnel is provided with anti-falling stone check blocks, and backfill bodies are arranged between the anti-falling stone check blocks which are adjacent to the dark-cave part and the ground line. The ribbed-arch multi-arch tunnel has the advantages that: compared with cutting form, the rock body outside the tunnel can be completely free from being dug and disturbed, and only the rock body at the inner side the tunnel is dug, so the digging quantity is remarkably reduced, the digging quantity of the earth and stone can be greatly reduced, the work amount of the slope protection and the supporting structure can be greatly reduced, the damage of the environment and the disturbance of the mountain can be reduced, the construction and the operation safety of the deeply-buried side tunnel can be realized, the road traffic safety can also be improved, and the maintenance cost during the operation period can be reduced.
Description
Technical field
The utility model belongs to highway tunnel, is specifically related to a kind ofly be applicable to that shallow embedding is close to the multiple-arch tunnel of two-way road, mountain traffic.
Background technology
Multiple-arch tunnel is highway tunnel a kind of form of structure commonly used, have occupation of land less, linear smoothness, avoid the advantage of route framing outside the hole, be specially adapted to the sidehill tunnel built along the river valley, mountain area and on the hills, the short tunnel group that builds of low-relief terrain.Traditional multiple-arch tunnel up-downgoing route all is embedded in underground.But if orographic condition is subjected to further restriction, the side buried depth in the up-downgoing road is bigger, can build the tunnel, and the opposite side buried depth is less, can't build the tunnel.For such orographic condition, all only built single hole tunnel in the big side of buried depth in the past, then adopt the cutting scheme to pass through in the little side of buried depth.Adopt such technical scheme, often bring following technical problem: (1) needs the excavation cut slope in order to build the road of the more shallow side of buried depth, must destroy massif nature and ecological environment, and the formation high slope, not only increase construction costs, also can increase road operation maintenance difficulty; (2) during the more shallow dypass moat of buried depth excavation, can the disturbance massif, reduce sloping body stability, face greater risk when causing the bigger side tunneling of buried depth; (3) the bigger side tunnel excavation of buried depth further produces disturbance to massif, influences the side slope of the less side of buried depth and the safety of retaining structure thereof, and may cause in the operation process massif slump or Rolling Stone to be fallen on the road surface of the less side of buried depth, threatens traffic safety; (4) in order to guarantee that buried side builds the safety in tunnel, the cutting that must make the less side of buried depth promptly adopts the route form of up-downgoing framing away from the bigger side tunnel of buried depth, give linear bring unfavorable.This shows, in the hill side road line of the strict restriction of landform, adopt buried side to repair the repair the roads scheme of moat of tunnel, shallow embedding side, all having problems aspect economy, safety, environment and the construction operability.
Summary of the invention
Should build the tunnel more greatly in order to solve in the up-downgoing circuit side buried depth, and the less restricted landform problem that can not build the tunnel according to a conventional method of opposite side buried depth, the utility model provides a kind of ribbed arch formula multiple-arch tunnel.
Concrete technical solution is as follows:
A kind of ribbed arch formula multiple-arch tunnel comprises the dark hole tunnel of a side, mid-board; Opposite side is ribbed arch formula open cut tunnel tunnel, and the buried depth in described ribbed arch formula open cut tunnel tunnel is dark cavity portion than ninor feature one side, and opposite side is the ribbed arch open cut tunnel part of being made up of two above ribbed arches, and the spacing between the adjacent ribbed arch is a 4-8 rice; Dark cavity portion and ribbed arch open cut tunnel part adjacent top along the length direction in ribbed arch formula open cut tunnel tunnel are provided with the rock-fall proof block, are provided with the backfill body between rock-fall proof block adjacent with dark cavity portion and the above-ground route.
Described ribbed arch open cut tunnel bottom is provided with the open cut tunnel basis, and described open cut tunnel basis is grouted anchor bar or pile foundation.
The ribbed arch circular arc excursion of described ribbed arch open cut tunnel is the 1/3-1/6 circular arc.
Ribbed arch in the described ribbed arch formula open cut tunnel is reinforced concrete ribbed arch or concrete filled steel tube ribbed arch or steel reinforced concrete ribbed arch or shaped steel ribbed arch.
Ribbed arch formula multiple-arch tunnel is with the form of structure of multiple-arch tunnel, adopt the tunnel structure that buries entirely in the bigger side of buried depth, the less side of buried depth then adopts penetrating ribbed arch formula open cut tunnel structure, both can avoid cutting excavation to cause massif disturbance and environmental disruption, reduce side slope protection and retaining structure, can avoid up-downgoing route framing again, favorable applicability be arranged at mountain area shallow embedding short tunnel difficult wiring section.
Useful technique effect of the present utility model is: compare with the cutting form, adopt ribbed arch formula open cut tunnel structure in the less side of buried depth, geotechnical body beyond the tunnel can not excavated fully, disturbance, the inboard geotechnical body of tunneling, excavated volume significantly reduces, can reduce the engineering quantity of earthwork evacuation amount, side slope protection and retaining structure greatly, reduce to environment damage with to the disturbance of massif, and help the construction and the operation security in buried side tunnel, also improve the safety of road traffic simultaneously, reduced the maintenance cost of operation phase.
