Abstract
The utility model discloses a double-multiple-arch tunnel middle wall provided with a drainage system. The middle wall is located between a left side tunnel main cave and a right side tunnel main cave. The top of the middle wall is of a Y-shaped structure. Left side tunnel main cave secondary lining and right side tunnel main cave secondary lining are respectively joint with the top of the middle wall in a matching and corresponding mode. A tube pervious to water is arranged, in the longitudinal direction of a tunnel, at the bottom of the middle wall of the Y-shaped structure. A plurality of vertical drainage tubes are arranged, in the longitudinal direction of the tunnel, in the middle wall. The upper port of each vertical drainage tube is communicated with the tube pervious to water. The lower port of each vertical drainage tube is communicated with a tunnel drainage ditch through a transverse drainage tube. The double-multiple-arch tunnel middle wall has the advantages of being simple in structure, convenient to construct, and capable of effectively reducing the thickness of a middle segregating wall, reducing project cost, reducing areas occupied by outer guide lines of the tunnel, saving land resources and the like.
Description
Technical field
The utility model belongs to the tunnel construction technology field, particularly wall in a kind of double-arched tunnel that is provided with drainage system.
Background technology
Along with the development of highway construction, increasing highway is gradually along entering the mountain area.Building reducing the traffic accident incidence of highway tunnel shortened the operation mileage, improves road speed and comfortableness; effectively prevent from filling out owing to roadbed is high and deep-cut the various geological disasters that cause; preserve the ecological environment, save the soil, promote economic development and played positive effect.Since multiple-arch tunnel compare with separate tunnel have advantages of linear more smooth-going, take up an area few, in, short tunnel build in multiple-arch tunnel more and more selected.But traditional multiple-arch tunnel adopts wall construction in the integrated straight and since technological problems exist always in wall top seepy question, cause many problems for the operation maintenance.
The wall roof construction is " individual " font in the tradition multiple-arch tunnel, and therefrom wall two side roof part grouting way are adopted in the top backfill of middle wall, and this kind technique causes Zhong Qiangding can't backfill closely knit, and middle wall and main hole lining cutting joining place are prone to drainage.Be head it off, many unit centering wall constructions have carried out repeatedly optimizing, and have produced in wall construction in the three-layer combined song, three layers of straight middle wall structure, the five layers of song wall construction etc.Make main hole two linings even just prop up independently, the waterproof system is identical with separate tunnel, and this has improved middle wall waterproof effect, but has thickeied middle wall, has increased outside construction costs, the tunnel and has taken up an area.
The utility model content
The purpose of this utility model is to improve the defective of prior art, and wall in a kind of double-arched tunnel that is provided with drainage system is provided.Should in wall will be in " individual " type structure on wall top change " Y " type structure into, and in establish within the walls some vertical drainage pipes, directly be discharged to the country rock infiltration under the road surface, master hole, tunnel, left side and in the tunnel drainage ditch under the road surface, master hole, tunnel, right side and discharge the tunnel; Have simple in structure, easy construction, and can effectively reduce mid-board thickness, reduce construction costs, reduce the tunnel outer lead and take up an area, the advantage such as economize the land resource.
For achieving the above object, the utility model adopts following technical proposals:
Wall in a kind of double-arched tunnel that is provided with drainage system, described middle wall is between master hole, tunnel, left side and master hole, tunnel, right side, and Zhong Qiangding is y-type structure; Corresponding joint is mated with master hole, tunnel, left side secondary lining, master hole, tunnel, right side secondary lining respectively in described middle wall top;
Bottom on the middle wall top that is y-type structure is provided with a water-permeable pipe along the tunnel longitudinal direction, in along the tunnel longitudinal direction some vertical drainage pipes are set within the walls, described vertical drainage pipe upper port is communicated with water-permeable pipe, and the vertical drainage infratubal port is communicated with the tunnel drainage ditch by transverse drain.
Further, described water-permeable pipe top is provided with some permeable holes.
Further, lay rubble seepage flow layer in the bottom on the middle wall top that is y-type structure, in guaranteeing during the backfill of wall head space hole cement paste do not infiltrate rubble seepage flow layer, lay one deck waterproofing course at described rubble seepage flow layer top; Described rubble seepage flow layer height position is lower than described middle wall and master hole, tunnel, left side, more than the vertical constuction joint position 10cm of secondary lining junction, master hole, tunnel, right side.
Further, in the rubble seepage flow layer bottom, bottom on the middle wall top that is y-type structure waterproofing course is set, the thick BAC adhesive waterproof coil of one deck 2mm is set simultaneously.
Further, but the described middle wall that is y-type structure withstand on master hole, tunnel, left side, vertical constuction joint place, secondary lining junction, master hole, tunnel, right side establish in the slip casting of external labeling type waterstop buried water stop each.
The utility model is compared with existing product, has following actively useful effect:
1, wall top node bind mode in the change, the wall top is y-type structure among the present invention, change " individual " type structure on wall top in original into " Y " type structure, making master hole, tunnel, left side, master hole, tunnel, right side be connected the abutment with middle wall is arranged on the wall top that is y-type structure, and in establish within the walls some vertical drainage pipes, directly be discharged to country rock infiltration under the road surface, master hole, tunnel, left side and in the tunnel drainage ditch under the road surface, master hole, tunnel, right side and discharge the tunnel.
2, strengthened middle wall top both sides main structure construction seam waterproof measure.
3, strengthened radially consolidation grouting of middle pilot tunnel vault, middle pilot tunnel vault is reinforced through the country rock of excavation disturbance repeatedly, reduce earth's surface percolating water and infiltrate, thereby reach the effect that in multiple-arch tunnel wall and master hole, tunnel, left side, junction, master hole, tunnel, right side are avoided leaking and improved Mechanical behavior of middle wall.
Contrast wall construction mode in the three-layer combined straight middle wall of same head it off, three-layer combined Qu Zhongqiang, the five layer composite songs, its simple in structure, easy construction, and can effectively reduce mid-board thickness, reduce construction costs, reduce the tunnel outer lead and take up an area, economize the land resource.
