In order to solve the technical problem, the utility model discloses a following technical scheme:

a combined protection structure for falling rocks on a road side slope comprises a supporting shed positioned above the road, wherein the supporting shed comprises a lower upright post, an upper upright post and a cross beam plate, the lower end of the lower upright post is buried in the ground on one side of the road far away from the side slope, the upper end of the lower upright post is fixed with one end of the cross beam plate, and the other end of the cross beam plate is fixed with the side slope; the upper upright post is fixed at the upper end of the lower upright post.

The utility model discloses a strut crossbeam board of shed roof portion is planar structure, and the crossbeam board has increased the buffer in other words, makes the high greatly reduced of spring of falling stone to, through the setting of last stand, can prevent that falling stone spring from going out to strut the shed outside, the at utmost has reduced the damage of falling stone to road one side equipment.

Additionally, the utility model discloses a crossbeam board one side is direct fixed with the side slope, make full use of the favorable topography geology characteristics of side slope, has reduced the engineering volume of partly protection canopy to the investment has been reduced.

As a further improvement of the above technical solution:

in order to ensure the connection strength of the combined protection structure and the road, the lower end of the lower upright post is provided with a toe wall, the toe wall is provided with an anchoring part, and the anchoring part penetrates through the toe wall and then extends into the interior of the road foundation.

The other end of the beam plate is fixed on the first-stage pavement at the lower end of the side slope.

In order to ensure the connection strength between the combined protection structure and the side slope, an anchoring part is arranged at one end, fixed to the side slope, of the beam plate, and the anchoring part penetrates through the beam plate and then extends into the first-level pavement at the lower end of the side slope.

In order to ensure the strength of the combined protection structure, the supporting shed is of an integrally formed reinforced concrete structure.

In order to further prevent the falling rocks from damaging equipment on one side of the road, a protective net is fixed at the upper end of the upper upright post. And calculating the bounce height of the rockfall after the rockfall reaches the supporting shed according to rockfall motion analysis, and setting the sum of the heights of the protective net and the upper upright post to be greater than the bounce height, so that the damage of the rockfall to equipment on one side of the road can be effectively prevented.

Compared with the prior art, the utility model has the advantages of:

1. the utility model discloses both can prevent the damage to road traffic, can prevent the damage to road one side equipment again, the security improves greatly.

2. Compared with the traditional protective shed, the protective shed reduces the engineering quantity of a part of protective sheds and reduces the investment.

Illustration of the drawings: 1. a road; 2. equipment; 3. side slope; 4. a lower upright post; 5. an upper upright post; 6. a beam plate; 7. a protective net; 8. an anchoring member; 9. a toe wall; 10. and (4) falling rocks.

Detailed Description

The invention is further described below with reference to specific preferred embodiments, without thereby limiting the scope of protection of the invention.

Example 1:

as shown in fig. 1, the combined protection structure for falling rocks on a road slope of the embodiment includes a reinforced concrete supporting shed above the road, wherein the supporting shed includes a lower upright post 4, an upper upright post 5 and a beam plate 6.

The lower end of the lower upright post 4 is embedded in the ground on the side of the road 1 far away from the side slope 3, the upper end of the lower upright post 4 is fixed with one end of a cross beam plate 6, and the other end of the cross beam plate 6 is fixed on a first-stage pavement at the lower end of the side slope 3. The upper upright post 5 is fixed at the upper end of the lower upright post 4, and the upper end of the upper upright post 5 is fixed with a protective net 7.

The lower extreme of lower column 4 is equipped with toe wall 9, is equipped with a plurality of anchor assembly 8 (stock) on the toe wall 9, and a plurality of stocks run through and stretch into the inside of road foundation behind the toe wall 9.

The crossbeam board 6 is equipped with a plurality of anchor assembly 8 (stock) with the fixed one end of side slope 3, and many stocks run through the inside that stretches into the first level packway of side slope 3 lower extreme behind the crossbeam board 6.

The construction process of the road slope rockfall combined protection structure is as follows:

s1: excavating the road 1 to form the position of a toe wall 9;
