Abstract
The invention discloses a method for protecting and greening a rocky side slope, which relates to the field of side slope construction in highways, railways, hydroelectricity and municipal projects. The method is a combined method for protecting, reinforcing and greening the superficial layer of a rocky side slope, and comprises the following steps of: (1) smoothing the slope surface; (2) driving an anchor rod; (3) installing a water spray pipeline and a device; (4) excavating a pit groove for a ground beam, and laying a reinforcing cage for the ground beam; (5) pouring the whole ground beam by bundling the reserved reinforcing steel bar for the anchor rod and the reinforcing cage for the ground beam; (6) prefabricating and inserting a soil blocking plate; (7) filling farming soil; and (8) planting and maintaining rattan plants. The invention has the advantages of effectively conserving soil and providing the objective environment suitable for plant growth; pre-burying a water spray device, ensuring the humidity of soil and improving the survival rate of plants; and realizing the purpose of reinforcing and greening the superficial layer of the rocky side slope comprehensively, and the invention is suitable for the project for protecting and greening the rocky side slope in highways, railways, hydroelectricity and municipal projects.
Description
Technical field
The present invention relates to highway, railway, water power and municipal slope project construction field, relate in particular to a kind of method for protecting and greening of rock side slope; This method is the method that a kind of shallow-layer protective reinforcing of rock side slope combines with greening.
Technical background
In the construction of infrastructure such as present highway, railway, water power, often to excavate a large amount of side slopes.If side slope is not carried out protecting and greening, cause a large amount of secondary barrens and produce serious soil erosion and shallow failure etc. through regular meeting.Existing engineering slope adopts stone, concrete, building block etc. that side slope surface is covered in a large number, though these ways can the reinforcing side slope shallow-layer, causes the pollution of ecological disruption and vision easily.
Can the objective environment that be suitable for plant growing is provided effectively be the greening side slope key of success.The existing greening method of rock side slope has that the spray of spray sowing technology, organic substrate is planted, cement eco-species phytyl, plant cover concrete slope protection greening technology etc.Though these method titles are different, all be to adopt the sprayed mortar soil retaining technology in fact.Because the slope angle of rock slope is bigger, injected plant is difficult to be fixed up on this rock side slope; Though the part plant can be fixed, owing to rock side slope soil depletion, poor water retention property are difficult to survive.
Summary of the invention
Purpose of the present invention just is to overcome the shortcoming and defect that prior art exists, and a kind of method for protecting and greening of rock side slope is provided.
The object of the present invention is achieved like this:
Physical feature at rock side slope, adopt the method for anchor pole and grade beam that rock side slope is carried out the shallow-layer protective reinforcing, on grade beam, insert simultaneously breast boards, compost is filled out on the breast boards upper berth, so just can effectively provide green plants required compost, compost upper seeding wheel rattan class plant side slope be afforested at last.The characteristics that rattan class plant has is drought-resistant, barren-resistant, well developed root system, coverage are good, be easy to survive can play good landscape effect.In order to regulate the humidity of compost, at default water pipeline in top, slope and sprinkler.
Specifically, the present invention includes the following step:
1. smooth domatic;
2. set anchor pole;
3. water pipeline and equipment are installed;
4. excavate grade beam hole groove, lay the grade beam reinforcing cage;
5. anchor pole reserved steel bar and the colligation of grade beam reinforcing cage, it is integrated poured to carry out grade beam;
6. prefabricated and insert breast boards;
7. compost is filled out in the shop;
8. the plantation, maintenance rattan class plant.
The present invention has following advantage and good effect:
1. carry out solid soil effectively, the objective environment that is suitable for plant growing is provided;
2. pre-buried sprinkler guarantees soil moisture, improves the survival rate of plant;
3. realize rock side slope is carried out shallow layer reinforcement and the purpose of afforesting integrated treatment, be applicable to the protecting and greening engineering of the rock side slope of highway, railway, water power and municipal engineering.
