Abstract
The utility model discloses a roadbed side slope retaining protection structure, which comprises a retaining wall and anchor rods, wherein the retaining wall supports and protects a roadbed slope, the anchor rods are longitudinally arranged along the retaining wall, one ends of the anchor rods are buried in the retaining wall, and the other ends of the anchor rods are driven into the roadbed. The anchor rods are arranged between the retaining wall and the roadbed, the retaining wall is connected and reinforced with the roadbed through the anchor rods, the retaining wall, the roadbed and the anchor rods simultaneously form a stable integral protection structure, and the stability of the roadbed can be ensured. Therefore, the roadbed side slope retaining protection structure has the advantages that the excavation of many natural rock layers is not needed, the construction difficulty is reduced, the engineering cost is reduced, in addition, the damage to a nature soil layer and the rock layer is reduced, and the integrity and the stability of the original rock layer are ensured.
Description
Technical field
The utility model belongs to technical field of civil engineering, is specifically related to a kind of roadbed side slope retaining protection structure.
Background technology
Along with the development of society, the expansion in city, the road network pace of construction is more and more faster, and building of road is more and more frequent.For the area that is in heavy mound, mountain ridge type landform, hypsography is bigger, thus the road foundation side slope to adopt barricade to carry out the chance of supporting a lot, and in the highway section, abrupt slope, building of traditional gravity barricade will cause following several kinds of problems:
1, because the slope is steep, and the foundation excavation difficulty of barricade is big, and mostly this type abrupt slope be solid rock, and the excavation cost is higher;
2, according to traditional single gravity wall-retaining structure form, cross dimensions is bigger, and construction costs is high, and wall back of the body backfill area is little, can't carry out mechanical ramming, so Subgrade Compaction usually can not reach standard;
3, the excavation of present situation being stablized the rock stratum might cause the instability of rock stratum, has potential safety hazard.
Therefore, under this specific situation, be the problem of avoiding above traditional structure to exist, need a kind of novel roadbed side slope retaining of design protection structure, reduce nature rock stratum excavated volume as far as possible, guarantee rock stratum globality and stability.
Summary of the invention
In view of this, the utility model provides a kind of roadbed side slope retaining protection structure, and natural rock stratum excavated volume is little, can reduce the destruction of nature soil layer and rock stratum, guarantees the globality and the stability of former rock stratum as far as possible.
The roadbed side slope retaining protection structure of the utility model comprises the barricade of supporting roadbed side slope and the anchor pole of vertically arranging along barricade, and said anchor pole one end is embedded in the barricade, and the other end is squeezed in the roadbed.
Further, said barricade is the barricade of concrete monobloc cast;
Further, said barricade is the barricade of C20 sheet stone concrete monobloc cast;
Further, said roadbed is roadbed original state soil layer or rock stratum;
Further, said anchor pole is a Φ 25HRB335 reinforcing bar;
Further, also be provided with the gravel backfill part between said barricade and the roadbed.
The beneficial effect of the utility model is: the utility model is provided with anchor pole between barricade and roadbed; Barricade is through anchor pole and roadbed connection reinforcing; Barricade, roadbed and anchor pole have been formed a stable whole safeguard structure jointly, can guarantee the stability of roadbed; Therefore, the utility model need not to excavate the nature rock stratum in a large number, has reduced difficulty of construction, has reduced construction costs, and has reduced the destruction of natural soil layer and rock stratum, has guaranteed the globality and the stability of former rock stratum.
Description of drawings
For the purpose, technical scheme and the advantage that make the utility model is clearer, will combine accompanying drawing that the utility model is done further to describe in detail below, wherein:
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below will be with reference to accompanying drawing, the preferred embodiment of the utility model is carried out detailed description.
Fig. 1 is the structural representation of the utility model; As shown in the figure, the roadbed side slope retaining protection structure of the utility model comprises the barricade 2 of supporting roadbed 1 side slope and the anchor pole of vertically arranging along barricade 23; Said anchor pole 3 one ends are embedded in the barricade 2, and the other end is squeezed in the roadbed 1.
In the present embodiment, said barricade 2 is the barricade of C20 sheet stone concrete monobloc cast; The barricade of concrete monobloc cast is higher with respect to the barricade intensity that rock layer stacks block, and structure is more firm.
In the present embodiment, said roadbed 1 is roadbed original state soil layer or rock stratum; Avoid excavation as far as possible, reduce difficulty of construction, avoid the destruction of nature soil layer and rock stratum simultaneously.
In the present embodiment, said anchor pole 3 is a Φ 25HRB335 reinforcing bar; Φ 25HRB335 reinforcing bar is the hot-rolled ribbed indented bars of nominal diameter 25, yield strength 335.
In the present embodiment, also be provided with gravel backfill part 4 between said barricade 2 and the roadbed 1; Gravel backfill part 4 is carried out mechanical ramming, is proposed road scope 5 on it.
The utility model is provided with anchor pole 3 between barricade 2 and roadbed 1, barricade 2 is through anchor pole 3 and roadbed 1 connection reinforcing, and barricade 2, roadbed 1 and anchor pole 3 have been formed a stable whole safeguard structure jointly, can guarantee the stability of roadbed 1; Therefore, the utility model need not to excavate the nature rock stratum in a large number, has reduced difficulty of construction, has reduced construction costs, and has reduced the destruction of natural soil layer and rock stratum, has guaranteed the globality and the stability of former rock stratum.
Explanation is at last; Above embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although the preferred embodiment through with reference to the utility model is described the utility model; But those of ordinary skill in the art should be appreciated that and can make various changes to it in form with on the details, and the spirit and the scope of the utility model that does not depart from appended claims and limited.
