Embodiment 1

[0037] Such as Figure 1-Figure 5 As shown, a high-strength preloaded anchor rod and prefabricated reinforced concrete slab combined slope greening structure, including a water collection tank 1 set on the top of the slope, and a number of transverse prefabricated steel bars are evenly arranged on the slope surface from top to bottom The concrete slab 7 and the horizontal prefabricated reinforced concrete slab 7 are fixed and installed on the slope surface through a plurality of high-strength pre-stressed anchor rods 3, and each horizontal prefabricated reinforced concrete slab 7 is placed with a horizontal water supply pipe 5 with both ends closed, and the horizontal water supply pipe 5 is provided with a plurality of water outlet holes 9, and the outer surface of the horizontal water supply pipe 5 is wrapped with a dialysis membrane. Each horizontal water supply pipe 5 is connected with the water collection tank 1 through the vertical water supply pipe 6. concrete piles;

Embodiment 2

[0047] A method for slope greening using the above structure, the method includes the following steps:

[0048] Step 1: Clean up the side slope, using manual and simple machinery to remove gravel and sundries on the side slope, the order should be from top to bottom;

[0049]Step 2: Drill multiple anchor holes on the slope surface, insert the anchor rod 11 with the first rigid disc 15 into the anchor hole, add cement mortar with a mass content of 10-30% expansion agent into the anchor hole to solidify A high-strength preloaded anchor body 16 is prepared, and a second rigid disk 21 is arranged on the top of the high-strength preloaded anchor body 16, so that the axial pressure on the anchor rod 11 is converted into a lateral pressure, and the pullout resistance of the anchor rod is increased. Add cement mortar into the anchor hole and solidify to make ordinary mortar anchor body 17;

[0050] Step 3: Connect the horizontal prefabricated reinforced concrete slab 7 and the longit...

Abstract

A high-strength pre-pressed anchor rod and prefabricated reinforced concrete slab combined slope greening structure comprises a water collection tank arranged on the top of a slope; the face of the slope is evenly provided with a plurality of transverse prefabricated reinforced concrete slabs from top to bottom; the transverse prefabricated reinforced concrete slabs are fixedly installed on the face of the slope through a plurality of high-strength pre-pressed anchor rods and are provided with transverse water feeding pipes with the two ends closed; a plurality of water outlet holes are formedin the transverse water feeding pipes; the outer surfaces of the transverse water feeding pipes are wrapped with dialysis membranes; and the transverse water feeding pipes communicate with the watercollection tank through longitudinal water feeding pipes and are covered with vegetation concrete accumulation bodies containing plant seeds. According to the high-strength pre-pressed anchor rod andprefabricated reinforced concrete slab combined slope greening structure and method, the problem that existing slope greening structures cannot achieve safety slope protection and slope greening at the same time within the short time can be solved, and the greening area is increased while slope treatment is met.

Description

technical field [0001] The invention relates to the technical field of slope greening, in particular to a slope greening structure and method combined with high-strength preloaded anchor rods and prefabricated reinforced concrete slabs. Background technique [0002] Our country has a vast territory and many mountains, and some areas have formed slopes with potential safety hazards due to the influence of the environment. In order to promote exchanges between regions and promote the development of regional economies, the country has vigorously promoted the construction of road and railway infrastructure. In the construction of highways and railways, due to the severe and changeable terrain, it is necessary to excavate a large number of slopes. The slope after excavation lost its original vegetation cover protection, resulting in serious water and soil erosion in the excavated area, causing damage to the harsh ecological environment; at the same time, the steep slope formed a...
