Description
Technical field
The present invention relates to geotechnical engineering reinforcing side slope technique field, in particular to a kind of for In A Crushed Rock cut slope
Slope protection structure.
Background technique
In A Crushed Rock cut slope is extremely common in mountain railway, highway engineering, and often molding effect is poor for slope surface, and bumps are not
Flat and shiver stone sediment throughout.To meet slope surface protection against erosion and stability requirement, protected, traditional protection type master
Have following several: (linked network) gunite concrete (or mortar) slope protection, entity slope protection, Anchored frame beam combination plant protection, base
Material plants life, hole window slope protection combination plant protection etc..
Major defect existing for traditional protection type is as follows: (1) (linked network) gunite concrete (or mortar) slope protection, entity
Slope protection slope surface is totally-enclosed, without greening, mutually conflicts with environmentally protective construction theory, is phased out at present；(2) Anchored frame beam
, investment high in conjunction with plant protection engineering cost is greatly；(3) substrate planting for ecologic protection works well, suitable for there is higher aesthetic effect
Side slope protection, but its engineering cost is higher；(4) hole window slope protection combination plant protection has taken into account beautiful and cost-effectiveness requirement, but
Basis is only arranged in existing hole window slope protection at slope foot, is directly layed on slope surface, due in In A Crushed Rock Slope slope surface
Sediment be difficult in the construction process, hole window slope protection bottom surface and excavate slope surface between due to sediment presence, close note compared with
Difference, globality is bad, and slope protection is under the effect of gravity easily along slope surface creep, and after sediment is lost by rain infiltration sapping, slope protection
It comes to nothing phenomenon between slope surface excavating, cause hole window slope wall cracking, damaged or even fail.
Existing hole window slope protection is a kind of technology maturation, the convenient and fast side slope protection pattern of construction, can be using grouting
Slabstone is built or concreting.Therefore, it is necessary to develop a kind of and side slope good integrity, beauty and economy on this basis
The slope protection structure for In A Crushed Rock cut slope taken into account.
Summary of the invention
The purpose of the present invention is to solve the deficiency of the above background technology, provides a kind of and side slope good integrity, beauty
The slope protection structure for In A Crushed Rock cut slope taken into account with economy.
The technical solution of the present invention is as follows: a kind of slope protection structure for In A Crushed Rock cut slope, including it is located at slope
Whole hole window slope wall on face, on the hole window slope wall transversely, longitudinal gap providing holes window, feature exists
In the longitudinal strip groove of recessed formation, a plurality of longitudinal direction bar shaped channel lateral interval are arranged the slope surface along longitudinal direction, the hole window
Slope wall bottom surface is equipped with a plurality of longitudinal strip footing, and each longitudinal strip footing is correspondingly embedded in each longitudinal strip groove.
Preferably, transversely the lateral strip groove of recessed formation, a plurality of transverse direction strip groove longitudinal gap are set the slope surface
It sets, a plurality of lateral strip groove is connected to form latticed, the hole window slope wall bottom surface with a plurality of longitudinal strip groove
Equipped with a plurality of lateral strip footing, each lateral strip footing is correspondingly embedded in each lateral strip groove.
Preferably, the cross section of longitudinal strip footing is rectangle.
Further, the longitudinal section of the lateral strip footing is rectangle.
Further, hole window is horizontally arranged at interval and embarks on journey on the hole window slope wall, the setting of multirow hole window longitudinal gap
At array, the longitudinal direction bar shaped base bits are between wherein adjacent two column hole window in region.
Further, hole window is laterally set with the first spacing d, the second space D alternate intervals on the hole window slope wall
It sets, the first spacing d is less than the second space D, and the longitudinal direction bar shaped basis instrument is in two column that adjacent spacing is the first spacing d
Between the window of hole in region.
Further, the first spacing d is 0.5~1m, and the second space D is 1.5~2m.
Further, hole window is horizontally arranged at interval and embarks on journey on the hole window slope wall, the setting of multirow hole window longitudinal gap
At array, the transverse direction bar shaped basis instrument is between the window of each adjacent rows hole in region.
Further, 0.8~1m of adjacent rows hole window longitudinal gap is arranged.
Preferably, longitudinal bar shaped depth of foundation is not less than 0.4m.
It is laterally along route extending direction to be longitudinal along slope surface inclined direction in the present invention.
The invention has the benefit that
1. longitudinal strip footing and existing hole window slope wall are organically combined, the presence of longitudinal strip footing is greatly improved
Hole window slope wall and In A Crushed Rock cut slope are formed organic whole, not only by the bite force of slope protection and slope surface
Overcome existing hole window slope wall easily along slope surface creep, come to nothing, cracking failure the disadvantages of, and propose a kind of technology at
Novel protective structure ripe, construction is convenient and In A Crushed Rock Slope can form organic whole, beautiful and economy is taken into account, has
Broad application prospect.
2. longitudinal strip footing, lateral strip footing are formed into grid type and existing hole window slope wall organically combines, into
One step enhances the bite force of slope protection and slope surface, has the advantages that construction is convenient, good with side slope occlusion property.
