Abstract
The utility model belongs to the technical field of railways, highways and municipal over-mountain tunnels, and particularly relates to a protruding type environment-friendly tunnel portal with supports. The protruding type environment-friendly tunnel portal comprises an open cut tunnel structure, tunnel portal end walls for supporting a tunnel entrance slope are arranged on the two sides of the open cut tunnel structure, side slope supporting structures are arranged on the outer sides of the tunnel portal end walls along the two sides of a roadbed, and green protective layers are laid on the surface of the tunnel entrance side slope and the surface of the tunnel entrance slope. The protruding type environment-friendly tunnel portal has the three major functions of protecting the side slope and the slope, backfilling an open cut tunnel and achieving attractiveness of the landscape of a tunnel entrance at the same time, stability of the tunnel entrance side slope and stability of the tunnel entrance slope can be effectively improved, and the surrounding environment of the tunnel portal is improved.
Description
Technical field
The utility model belongs to railway, highway and municipal over mountain line tunnel technical field, is specifically related to the protruding-type environment-friendly type portal that a kind of band props up gear.
Background technology
Portal is the throat in tunnel, is also unique exposed parts of tunnel structure.Stable from Rock And Soil, near tunnel portal, Rock And Soil is all more broken loose usually, is easy to unstability formation and caves in.Reasonably select the portal form, for stablizing hole, make the threats such as vehicle is not caved in, falling rocks most important.Simultaneously portal structure also should focus on beautifying and with the coordination of surrounding enviroment.
The portal pattern that mountain tunnel is commonly used has headwall formula, aileron formula, encircles frame, cuts bamboo formula etc.Headwall formula, wing wall tunnel portal are applicable to that hole is precipitous, the hole of massif bias voltage, and its shortcoming is that the hole excavated volume is large, are unfavorable for that Bian Yang slope, hole is stable, and quantity of masonry is large, with the surrounding enviroment inaccurate coordination; Cut bamboo formula portal and be applicable to mild, the open location of landform, natural environmental protection, shortcoming is without a gear effect to Bian Yang slope, hole.How to realize building the environment-friendly type portal on precipitous bias voltage massif, control Bian Yang slope, hole excavation height, reduce and take up an area, reduce artificialization vestige simultaneously, beautify the hole view, with surrounding enviroment, coordinating is current problem demanding prompt solution.
Summary of the invention
The purpose of this utility model is exactly the deficiency existed in order to solve the above-mentioned background technology, the protruding-type environment-friendly type portal that provides a kind of band to prop up gear, it can effectively improve Bian Yang slope, hole stability, improve the tunnel portal surrounding enviroment.
The technical solution adopted in the utility model is: a kind of band props up the protruding-type environment-friendly type portal of gear, comprise open-cut tunnel structure, described open-cut tunnel structure both sides are provided with the support hole and face upward the portal headwall on slope, the portal headwall outside is provided with the slope supporting structure along the roadbed both sides, and surface, Bian Yang slope, described hole is equipped with the Green Protection layer.
Further, between described open-cut tunnel structure and portal barricade, adopt anchor rib to be connected.
Further, described portal headwall top cross is provided with faces upward the gutter, slope, and described portal headwall inside has and is communicated with the headwall drain hole of facing upward gutter, slope and underdrainage passage.
Further, have spilled water hole on described slope supporting structure.
Band of the present utility model props up the protruding-type environment-friendly type portal of gear and takes into account side slope protection, open cut tunnel backfill and the large major function of hole view three simultaneously, both solved current headwall formula, the wing wall tunnel portal landscape effect is poor, with the inharmonic problem of surrounding enviroment, solved again the problem that bamboo formula portal can't effectively prop up gear of cutting, effectively reduce the hole excavation, be conducive to the limit, hole and face upward slope stability, have a extensive future.
Between open-cut tunnel structure of the present utility model and headwall, adopt anchor rib to be connected, improved resistance to overturning and the shock resistance of structure.Be provided with the hole headwall, can effectively stop by the open cut tunnel backfill of rain drop erosion, prevent that hole from facing upward slope and slipping and collapse.Be provided with the drainage systems such as gutter, spilled water hole, timely and effective eliminating earth's surface and underground water, prevent that soft of soil from causing limit to face upward the slope unstability.Be provided with the slope supporting structure in the headwall outside along the roadbed both sides, can reduce the roadway excavation height, effectively improve Tunnel slope stability.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, is convenient to be well understood to the utility model, but they do not form and limit the utility model.
As Figure 1-3, the utility model comprises open-cut tunnel structure 1, described open-cut tunnel structure 1 both sides arrange to be supported hole and faces upward the portal headwall 2 on slope, and between open-cut tunnel structure 1 and portal barricade 2, employing anchor rib 7 is connected, and can improve resistance to overturning and the shock resistance of open-cut tunnel structure.
Described portal headwall 2 top cross are provided with faces upward gutter, slope 6, and described portal headwall 2 inside have and are communicated with the headwall drain hole 5 of facing upward gutter, slope and underdrainage passage, have spilled water hole 4 on slope supporting structure 3.Be provided with the drainage systems such as gutter, spilled water hole, can get rid of timely and effectively earth's surface and underground water, prevent that soft of soil from causing limit to face upward the slope unstability.
The utility model band props up the sequence of construction of protruding-type environment-friendly type portal of gear as shown in Fig. 4-7, at first carry out the construction of open cut tunnel thematic structure, then carry out the construction of portal headwall, gutter, drain hole in the open-cut tunnel structure both sides, in the construction of carrying out the Tunnel slope retaining structure, finally carry out the open cut tunnel limit and face upward slope backfill greening construction, lay the Green Protection layer.
The content be not described in detail in this manual belongs to the known prior art of professional and technical personnel in the field.
