Detailed Description
The invention is described in detail below with reference to the figures and the specific embodiments.
Referring to fig. 1-4, a construction method of a sash beam slope greening system comprises the following steps:
step one, cleaning a slope surface 11: the broken stones, the pumice stones and the sundries on the slope surface 11 are cleaned, the dangerous situation of the slope surface 11 is integrally checked, and the loosened dangerous rocks are pried off by a crowbar, so that the slope surface 11 is integrally stable, flat and clean.
Step two, fixed-point paying-off: the slope of the whole stacked side slope is adjusted, the position of the lattice beam 2 is determined according to the actual condition of the rock side slope 1, the fact that the whole slope after the ecological bags 3 are stacked is basically consistent with the outer vertical face of the lattice beam 2 is guaranteed, and the bad phenomena of uneven fluctuation, verticality or reverse slope and the like cannot occur on the surface of the side slope after the ecological bags 3 are stacked.
Step three, pouring a slope bottom 82: in the construction process of the slope bottom 82 foundation, a foundation trench needs to be dug at the bottom of the rock slope 1, the foundation trench needs to be dug down to a hard rock layer so as to ensure the strength and firmness of the slope bottom 82 foundation, and then the concrete slope bottom 82 is poured.
And fourthly, pouring the lattice beam 2, erecting a 30cm multiplied by 40cm reinforced concrete longitudinal beam 22 at the angle of the slope 11 of the well-laid rock slope 1 every 10m from the slope bottom 82 foundation, and then pouring a 30cm multiplied by 40cm reinforced concrete cross beam 21 longitudinally along the plane vertical to the mountain body every 6-8 m so as to be connected with the vertical longitudinal beam 22. The lap joints of the cross beam 21 and the longitudinal beam 22 are all welded by a welding machine.
Step five, stacking the ecological bags 3; ecological bags 3 are stacked in the lattice beams 2, the ecological bags 3 on the first layer are all paved in the T direction, and the bags are leveled from the front to the back, so that the ecological bags 3 are arranged one by one. After the bottom layer ecological bags 3 are properly placed, the ecological bags 3 and the backfill behind and in front of them are compacted to prevent the ecological bags 3 from moving. When the ecological bags 3 are stacked, one layer of the stacking is adopted, the second layer is transversely arranged, the ecological bags 3 of the next layer are pressed with the ecological bags 3 of the previous layer, and the interlocking performance is achieved by walking on the ecological bags 3 or compacting by a small-sized road roller. And paving a layer of reinforced net 23 on every five layers of ecological bags 3, reinforcing the reinforced net 23 and the rock slope 1 by using an anchor rod 24, continuously placing the ecological bags 3, and tamping the backfill soil. In this way, a strong connection is formed between the reinforced net 23 and the ecological bag 3.
When the ecological bags 3 are stacked, firstly, a layer of ecological bags 3 is paved, and a small-sized tamping machine is used for tamping. Then, the connecting buckle 4 is used for straddling the two ecological bags 3 at the bottom layer, a proper amount of cement paste is smeared on the ecological bag 3 at the position corresponding to the connecting buckle 4, and then the connecting buckle 4 is placed to straddle the two ecological bags 3. Finally, a proper amount of cement paste is smeared on the connecting buckle 4, the second layer of the ecological bag 3 is installed above the connecting buckle 4, and then the ecological bag is tamped by a machine. Meanwhile, the gaps between the two ecological bags 3 of the upper layer and the lower layer are arranged in a staggered manner.
Step six, sealing and pouring a slope top 81; when ecological bag 3 pile to sash roof beam 2 top, at the top of sash roof beam 2 of the top, beat one row of reinforced concrete row on 3 planes of ecological bag that pile well along the trend of rock side slope 1, beat into rock side slope 1 when doing the row one reinforcing bar interval 50cm, reinforced concrete row links into an organic whole with longeron 22 that extends simultaneously, links into an integral frame construction, has strengthened entire system's fastness and stability greatly. Then, a plurality of layers of ecological bags 3 are flatly stacked on the top row along the rock slope 1 to be used as drainage ditches, and water on the mountain is drained from the drainage ditches.
Step seven, paving a covering soil layer 6: filling earth into the gap between the ecological bag 3 and the lattice beam 2; and covering soil on the surface of the ecological bag 3.
Step eight, planting a vegetation layer 7: planting a vegetation layer 7 on the outer side surface of the pouring lattice beam 2; according to the built sash beam 2 and the requirement of long-term greening, herbaceous plants 72 are planted by adopting a smearing method, and shrubs 71 are planted by adopting a direct planting method.
And step nine, maintenance management. And after the construction is finished, entering maintenance construction operation. The main working contents include watering, fertilizing, reseeding, deinsectization and the like. In the seed germination and seedling stage, the maintenance management should be enhanced, the slope 11 should be kept moist and rich in nutrients, and the seed germination and seedling growth should be ensured. After spraying, sprinkling water in the early morning according to soil and drought conditions, keeping the soil moist before emergence of seedlings, controlling the moisture after emergence of seedlings, and easily generating rotten seedlings and plant diseases due to the overhigh humidity for a long time. When watering, the water flow should be thin and slow. The direct current spray water gun is used for thoroughly watering each time, and watering is carried out according to the principle of small quantity, multiple times and uniformity. After seedlings come out of the soil neatly, watering times can be reduced, the seedlings are thoroughly dried and then watered, and the watering is carried out in the morning or after sunset in summer and at high temperature in the noon in winter. After seedlings emerge, watering is combined to apply foliar fertilizer (mainly nitrogen fertilizer) in time, and after seedlings emerge regularly, applying compound fertilizer mainly phosphorus potassium fertilizer to promote the seedlings to grow strongly and transversely. And after the growth is stable, fertilizing according to the growth requirement. Disease and pest prevention is mainly carried out, and comprehensive treatment is carried out. The diseases mainly comprise rust diseases and pythium rot, and the pests mainly comprise prodenia litura, cutworms and the like. In order to prevent the weed with strong infectivity from causing the vegetation degradation of the whole slope 11, artificial weeding or chemical agent weeding can be adopted.
Further, an adjusting mechanism 5 for finely adjusting the position of the ecological bag 3 is fixed between the ecological bag 3 and the rock slope 1; the adjusting mechanism 5 comprises a connecting male head 51 and a connecting female head 54; the connecting male head 51 comprises a male head base plate 52 fixed on the ecological bag 3 through a fastening bolt 57 and a connecting shaft 53 fixed on the end surface of one side of the male head base plate 52 far away from the ecological bag 3; the female connecting head 54 comprises a female base plate 55 fixed on the rock slope 1 through a fastening bolt 57 and a connecting groove 56 opened on the end surface of one side of the female base plate 55 far away from the rock slope 1; the connecting shaft 53 is hinged and sleeved in the connecting groove 56.
