Description
Technical field
The invention belongs to highway engineering highly weathered rock side slope protection fields, and it is strong to be specifically related to a kind of highway engineering
Effloresce Rock Slope ecological protection method.
Background technique
Currently, the ground such as Guizhou highway is mostly by mountain area, side slope is more, especially highly weathered rock side slope in rainwater and
It can successively be peeled off under slacking, landslide can even be generated by accumulating over a long period.Some framed framework protection of traditional means of defence,
Then native greening is returned, the native effect of this method time is poor, and afforestation effect is poor, and there are also carry out using the plant cover concrete occurred in recent years
Protection and greening, this method effect is preferable, but cost is higher, deficiency in economic performance.So we propose that one kind is new herein
Means of defence, not only can guarantee that side slope did not generated peeling and landslide in its natural state, but also have relatively good afforestation effect, it is this
Method meets the afforestation ecological theory and Environmental Protection Idea of current expressway construction very much, and cost is lower, to high speed
Highway construction side can also create preferable economic benefit.
Summary of the invention
The technical problems to be solved by the present invention are: providing simple process, the good highway of the lower afforestation effect of construction cost
Engineering highly weathered rock protecting slope ecology method.
In order to solve the above-mentioned technical problem, inventor obtains technical solution of the present invention by practice and summary, the present invention
Disclose a kind of highway engineering highly weathered rock protecting slope ecology method, comprising the following steps:
Step 1: side slope brush slope: after the completion of earthwork evacuation, reserving the 30cm-60cm thickness cubic metre of earth and stone not on side slope direction
It excavates, side slope carries out brush slope, and the brush slope gradient chooses 1:1.5, guarantees Slope leveling, cannot be uneven, if there is recess, adopt
It is filled up with mortar flag stone；
Step 2: preliminary side slope cleaning: further cleaning out float stone, surface dust, the sundries etc. in side slope, it is ensured that side slope
Upper smooth, no-sundries；
Step 3: side slope is slotted: slotting on side slope is lateral and vertical, slot dimension width 20cm-40cm, depth
15cm, fluting spacing are laterally and vertically 2m, and fluting is slotted using hand fit's pneumatic pick；
Step 4: being laid with wire netting: being laid with wire netting in entire slope surface；
Step 5: mortar flag stone: being grouted using M15 mortar to block stone, mortar flag stone is set to the slot excavated
It is interior；
Step 6: Spray turfing: using Spray turfing in grid；
Step 7: virescence maintenance: after Spray turfing construction is completed, non-woven fabrics is covered on side slope surface, to keep slope surface
Moisture simultaneously reduces rainfall and washes away to seed, promotes seed growth.
Preferably, wire netting is fixed using short brad in the step 4, wire netting carries out loose paving in slot, really
Wire netting will not generate stretching force after protecting mortar flag stone construction.
Preferably, wire netting is galvanized wire mesh in step 4.
Preferably, mortar flag stone accomplishes that mortar is full in step 5, is firmly bonded, and appearance accomplishes that lines are straight, and surface is flat
Whole, each working lining perps of mortar flag stone should mutually stagger, and must not penetrate through；Jointing uses recessed joint, and jointing equivalent width must not
Hollowing falls off.
Preferably, greening is existed with grass-seed and water-retaining agent, adhesive, green fiber covering and fertilizer in the step 6
Gelatinous mixed serum is mixed into stirring container with water, is sowed grass seeds by duster with pressure pump in wait broadcast in side slope.
Compared with prior art, the present invention can obtain following technical effect:
1. the present invention slots to highly weathered rock side slope after to the cleaning of highly weathered rock side slope brush slope, tool is constituted
There is the trough of mesh shape, be then laid with galvanized wire mesh on entire side slope face, pine paving is fixed in slot, is then adopted in slot
It is grouted with block stone, wire netting is fully pressed against under mortar flag stone, finally to carrying out Spray turfing in grid, when by one section
Between after, various vegetation grow in sash, and afforestation effect is all good, and protection effect is good, and present invention process is simple, and construction cost is lower
Afforestation effect is good, should be widely promoted.
2. the present invention, due to being highly weathered rock side slope, fluting is opposite to be easier to, it is noted that fluting range in grooving process
Outer rock tries not to be destroyed.
3. containing water-keeping material in mixed serum of the present invention is mainly covering effect.
