Each connecting beam consists of a vertical beam and an arc-shaped beam; one end of each vertical beam is fixed on one side wall pedestal and the other end of each vertical beam is connected with one end of the arc-shaped beam; the other end of the arc-shaped beam is fixed on the other side wall pedestal, and the arc of the arc-shaped beam is bumped to one side away from the vertical beam; reinforcing ribs are arranged between the vertical beams and the arc-shaped beams; a shearing beam is arranged between two adjacent connecting beams; and the upper surfaces of the shearing beams are covered with protective layers. Each connecting beam of the simple compressive shed tunnel consists of one vertical beam and one arc-shaped beam; one side of the vertical beam is in contact with a mountain and the arc-shaped beam has good compressive and deformation-resisting capabilities; the reinforcing ribs are arranged between the vertical beams and the arc-shaped beams and are capable of reinforcing the overall compressive performance of the simple compressive shed tunnel; the shearing beam is arranged between two adjacent connecting beams and is capable of expanding pressure to four sides; the protective layers are covered on the upper surfaces of the shearing beams and are capable of obstructing smaller falling rock.
Description
Technical field
The utility model relates to a kind of hangar tunnel, relates in particular to a kind of simple and easy resistance to compression hangar tunnel.
Background technology
To geological disasters such as the crag falling rocks of road, landslides, adopt a retaining, protective screening usually or build measure such as hangar tunnel and administer, existing hangar tunnel structure adopts arched girder to do support, utilizes crossbeam to process protective screening between arched girder; Have a lot of shortcomings like this, such as, landslide to the pressure of hangar tunnel in a side; Cause the hangar tunnel bulk deformation easily, secondly, adopt crossbeam to connect between arched girder; The resistance to compression damping effect is bad, is prone to pounded distortion by falling rocks, and protection effect is bad.
Summary of the invention
The purpose of the utility model just is that providing a kind of addresses the above problem, and integral body is difficult for compressive deformation, and the simple and easy resistance to compression hangar tunnel of resistance to compression, good damping effect.
To achieve these goals, the technical scheme of the utility model employing is such: a kind of simple and easy resistance to compression hangar tunnel comprises the both sides surbase; And be arranged on several tie-beams between the surbase of both sides, and said tie-beam is made up of a vertical beam and an arc beam, and said vertical beam one end is fixed on the surbase of one side; The other end connects an end of arc beam; The other end of said arc beam is fixed on the another side surbase, and the arc of arc beam side-prominent to away from vertical beam, is provided with a reinforcing rib between vertical beam and arc beam; Be provided with shear beam between adjacent tie-beam, said shear beam upper surface is coated with overcoat.
As preferably: the flexible anti protecting wire net that said overcoat removably connects for one or more layers and tie-beam.
As preferably: the two ends of said reinforcing rib lay respectively on vertical beam and the arc beam, and near the junction of vertical beam and arc beam.
Compared with prior art, the advantage of the utility model is: said tie-beam is made up of a vertical beam and an arc beam, and a side at vertical beam place contacts with massif, and the arc beam itself has good resistance to compression, non-deformability; Be provided with a reinforcing rib between vertical beam and arc beam, can strengthen the whole crushing resistance of the utility model, be provided with shear beam between adjacent tie-beam; Can be effectively with pressure to around expansion, avoid by the distortion of scheelite weight, the shear beam upper surface is coated with overcoat; Can stop less falling rocks, overcoat is the flexible anti protecting wire net that one or more layers and tie-beam removably connect, and protection effect is good; And be easy to remove and install, the two ends of reinforcing rib lay respectively on vertical beam and the arc beam, and near the junction of vertical beam and arc beam; The effect of its reinforcement is best, and the utility model is simple in structure, and is convenient and practical.

The specific embodiment
To combine accompanying drawing that the utility model is described further below.
Embodiment 1: referring to Fig. 1, Fig. 2, a kind of simple and easy resistance to compression hangar tunnel comprises both sides surbase 1; And several tie-beams that are arranged on 1 of both sides surbase, said tie-beam is made up of a vertical beam 2 and an arc beam 3, and said vertical beam 2 one ends are fixed on the surbase 1 of one side; The other end connects an end of arc beam 3, and the other end of said arc beam 3 is fixed on the another side surbase 1, and the arc of arc beam 3 side-prominent to away from vertical beam 2; 3 on vertical beam 2 and arc beam are provided with a reinforcing rib 4; Be provided with shear beam 5 between adjacent tie-beam, said shear beam 5 upper surfaces are coated with overcoat 6, and said overcoat 6 is the flexible anti protecting wire net that one or more layers and tie-beam removably connect; The two ends of said reinforcing rib 4 lay respectively on vertical beam 2 and the arc beam 3, and near the junction of vertical beam 2 and arc beam 3.
When the utility model is installed, abutment wall pedestal 1 is installed earlier, vertical beam 2 and arc beam 3 are installed again; And vertical beam 2 and arc beam 3 fixed in the junction, reinforcing rib 4 is set again, after the general frame moulding; Shear beam 5 is installed again, after shear beam 5 installs, covered protection layer 6.
One side at vertical beam 2 places contacts with massif, and arc beam 3 is positioned at the side away from massif, and arc beam 3 itself has good resistance to compression, non-deformability; 3 on vertical beam 2 and arc beam are provided with a reinforcing rib 4, can strengthen the whole crushing resistance of the utility model, are provided with shear beam 5 between adjacent tie-beam; Can be effectively with pressure to around expansion, avoid by the distortion of scheelite weight, shear beam 5 upper surfaces are coated with overcoat 6; Can stop less falling rocks, overcoat 6 is the flexible anti protecting wire net that one or more layers and tie-beam removably connect, and protection effect is good; And be easy to remove and install; The two ends of reinforcing rib 4 lay respectively on vertical beam 2 and the arc beam 3, and near the junction of vertical beam 2 and arc beam 3, the effect of its reinforcement is best.
