Detailed Description
In order to make the technical solution and advantages of the present invention more apparent, the present invention is described in detail below with reference to the accompanying drawings. See FIGS. 1-4. The invention provides a slope supporting and ecological management system and a construction process, which comprises a slope supporting structure, slope vegetation 3, a slope top intercepting ditch 2, a retaining wall 5 and a drainage ditch 6. The slope supporting structure comprises anchor rods 7 and lattice girders 20, and as shown in fig. 2-3, the anchor rods 7 comprise retaining rods 8, retaining holes 9, buckles 10, rotary mandrels 11, deep groove ball bearings 12, retaining teeth 13, springs 14, warping plates 15, bolts 16, rotary handles 17 and connecting keys 18. And the stopping rod 8 is provided with stopping teeth 13, and the stopping rod 8 is hinged on the rocker 15. The buckle 10 is fixed on a rotary mandrel 11, the rotary mandrel 11 is installed in the anchoring rod 7 through a deep groove ball bearing, a rotary handle 17 is arranged at the top end of the rotary mandrel 11, and the rotary handle 17 is fixed on the rotary mandrel 11 through a bolt 16 and a connecting key 18. The working principle of the anchor rod in the embodiment is as follows: at first buckle 10 joint makes spring 14 be in the limit compression state in the draw-in groove at backstop pole top, says afterwards that anchor rod 7 puts into anchor hole 4, then rotates twist grip 17 and makes the buckle of fixing on rotatory dabber 11 break away from the draw-in groove, and backstop pole 8 outwards opens around wane 15 under spring 14's elasticity, makes backstop tooth 13 and backstop pole 8 tooth go into in the side slope slide bed, increases side slope factor of safety.
As shown in fig. 4, the center of the lattice beam 20 is hollow for planting vegetation. The slope top intercepting drain 2 is arranged at a position with a certain distance from the slope top according to the condition of the side slope. The retaining wall 5 is made of rock-fill concrete, and the height and the width of the retaining wall depend on the condition of the side slope. The drainage ditch 6 is arranged on the edge of the retaining wall 5.
The integral construction process of the slope supporting and ecological management system provided by the invention comprises the following steps:
the slope supporting and ecological management system comprises the following procedures: building retaining walls, drilling anchoring holes, carrying out slope support, building slope top intercepting ditches, renovating slopes and planting slope vegetation. Firstly, the retaining wall is built, so that the side slope tends to be stable, and the retaining wall does not need to be built too high due to the fact that the retaining wall is a soil slope. And then, carrying out slope support under the condition that the slope is stable, wherein the slope support comprises the construction processes of punching anchoring holes, installing anchoring rods, pouring concrete into lattice beams and the like. If necessary, anchoring grouting can be carried out to increase the slope stability. And then constructing a slope top intercepting ditch at the slope top, wherein the intercepting ditch is a concrete waterproof intercepting ditch and is not suitable for being too deep. And finally, planting the vegetation, wherein the slope is treated before the vegetation is planted, and the slope is cleaned of obstacles which hinder the construction. The method comprises the following steps: removing the vegetation combination. Cleaning a contact surface of the original side slope above an opening line of the slope surface, wherein the cleaning width is 1.0-1.5 m, underground rhizomes are unnecessarily dug based on the removal of plant branches on the original side slope, and the part is used as a transition part between engineering and the original slope surface, namely a vegetation combination part; and removing weeds, fallen leaves, dead branches, pumice and the like on the surface of the slope. Finishing the treatment of the slope, preparing the vegetation seeds and carrying out the vegetation spray planting construction. Maintenance and management of the side slope are needed after spray planting construction is completed, and non-woven fabrics are covered on the surface of the base material 2-4 days after spray planting is completed, so that the effects of drip protection and temperature control can be achieved, the germination rate of plant seeds is improved, and the seeds can be prevented from being pecked by birds. Finally, maintenance and management for a long period, such as watering at regular time, deinsectization and the like, are required.
The foregoing is only a few preferred embodiments of the present invention, not all embodiments. Any modification, equivalent replacement, improvement and the like made based on the spirit and principle of the present invention shall fall within the protection scope of the present invention.
