Description
Technical field
This method is related to a kind of done for side slope and sprays in operation, and the method for preventing overly moist substrate clogging pipeline belongs to highway
Protecting slope ecology technical field.
Technical background
Road construction play the role of for expanding economy it is very important, but due to artificially constructing often to nature
Environment brings certain negative effect, and especially in mountainous region and hilly country, road construction generally requires to carry out cutting slope to massif
Equal operations, influence landform, excavate more.These side slopes excavated not only affect the whole landscape for destroying road, Er Qieduo
Number is not in stable state, the destructive behaviors such as regular appearance collapses, rubble slump, landslide, mud-rock flow.Therefore, right
In side slope improvement and greening measure be administer these side slopes important means.Using cement as the governance model of main material once
It is the important means that side slope is quickly administered, nowadays with China in recent years, increasingly pay attention to ecological afforestation, is built in road and bridge
Also begin to attach great importance to the ecological afforestation engineering of excavation slope in if.With being paid more attention to environmental protection, slope ecological is green
Chemical conversion is a new bright spot.Seed spraying technology is increasingly becoming the major measure of slope treatment, mainly has in alien earth sparging
Dry spray and two kinds of techniques of wet shot, relatively dry spray, wet shot working efficiency is more relatively high, but horizontal and vertical fed distance is all
More much shorter than dry spray, wherein the horizontal transport distance of dry spraying construction can reach 200m, but wet shot is generally in 30m or so；Dry spray is hung down
Straight fed distance is generally in 50m or so, but wet shot can only achieve 20m.For high gradient slope or larger side slope, wet spraying process
Obviously be not suitable for, but when side slope carries out dry spray operation, due to being influenced by factors such as rainfalls, the humidity of soil is glued
Degree is big, and plugging phenomenon is serious during sowing grass seeds by duster, and seriously restricts being normally carried out for dry spraying construction, not only delay the duration, waste raw material,
Cost is increased, and seriously affects sow grass seeds by duster quality and slope greening situation.

In the experiment for carrying out soil moved in improve the original improvement, the germination percentage of seed is tested respectively, data are shown in Table 1.
Table 1
In experiment, related experiment has all been carried out using adaptability herbaceous plant English ryegrass and Festuca Arundinacea.Due to incorporation
After sandstone material and vegetable matter, soil moved in improve the original is uniformly mixed, and density reduces, germination preferably, so spraying rear germination percentage
There is different degrees of raising.
When plugging wall sticking phenomenon occurs, soil moved in improve the original matrix is typically in the range of containing water quality between 20%~60%, in stirring
In the process, there is a large amount of agglomerated particle, waste raw material, while serious plugging wall sticking phenomenon occur during sowing grass seeds by duster, influence
Construction is smoothed out.
When mixing the soft materials such as sandstone hard material and cavings, sawdust, sandstone material can destroy in whipping process
The grain size of adhesive aggregation phenomenon between soil, sandstone material is less than the maximum particle diameter requirement for equipment of gushing.
Vegetable matter has water absorbing properties, can bulk matrix, reduce substrate water content by water absorbing properties and disperse
Matrix granule, guarantee, which is sowed grass seeds by duster, to be smoothed out, and being typically chosen is advisable with powdered.
Experiment：
1) side slope is tested on the right side of your the tenth bid section of hundred road of Anxin area.
Side slope belongs to low middle mountainous region looks, ROCK MASS JOINT cranny development, rock crushing on the right side of the tenth bid section of hundred roads；Road is filled out
Digging is smaller, and landform nature longitudinal slope is relatively slow, slope natural stability, and stability of slope problem is not present after road excavation, but due to quick-fried
It is broken to cause side slope surface layer rock crack broken.Meanwhile side slope multi-step is excavated in construction, ensures slope stability.But by
Complex in rock mass structure, step is not regular smooth enough.
Side slope slope foot width 102m, vertical height 52m, top of the slope to slope foot length is 59.4m.The side slope gross area is about
4980m2, 56.4 ° of whole angle, slope surface excavate two steps, be divided into three sections, middle and lower part slope surface angle is distributed between 65~75 °,
Top slope surface angle>80 °, near vertical.
2) since by influences such as rainfalls, aqueous soil moved in improve the original moisture content is 36.5%；
Prepare improvement soil moved in improve the original：Rubble and cavings are added into aqueous soil moved in improve the original, is uniformly mixed, aqueous soil moved in improve the original, rubble and
The mass ratio of cavings is 84%:8%:8%；Improvement soil moved in improve the original is sprayed on by road by the dry pressure spray process of soil moved in improve the original in massif side slope.
Dry spray operation is carried out using the aqueous soil moved in improve the original control group for not mixing sandstone and cavings simultaneously, the results are shown in Table 2.
It operates 5 days altogether.Every workday is 8 hours.
Table 2
| Control group | Embodiment 1 | Embodiment 5 | |
| Scrap rate | 5.6% | 0.34% | 0.21% |
| Average every workday plugging number | 8.2 | 1 | 0.4 |
| Average every workday normal spraying time (hour) | 2.60 | 7.67 | 7.88 |
Note：Scrap rate refers in the soil moved in improve the original mixed according to the ratio, can not pass through the visitor of hydroseeder sieve since particle is excessive
Native agglomerated particle.According to hydroseeder specification different from, the equipment requirement particle diameter used in experiment is not more than granular size
20mm belongs to waste material more than 20mm.
From, as can be seen that after using improvement soil moved in improve the original, scrap rate is substantially reduced, while plugging number is big in above-mentioned experimental data
Width reduce so that can ensure 7 normal spraying times more than hour in a working day, ensure that construction it is smooth into
Row.
The above description of test is done present method solves pipeline is blocked present in current dry pressure spray process without influencing
Pressure spray process is normally carried out, while improving construction efficiency, when the dry spray operation of side slope in a kind of preferable technology.
