Mortar rubble slope protection has the advantages of simple structure and obvious protective effect, but the hard covering of mortar rubble is not conducive to vegetation growth
In recent years, with the rapid development of expressways, the strength of rock and soil on slopes has decreased due to rain erosion, resulting in a decrease in anti-sliding force. Conventional protective structures are difficult to meet anti-sliding due to their simple structure, poor slope protection effect, and affecting vegetation restoration. Comprehensive requirements for slope protection and ecological restoration need to be further improved

Embodiment
[0034] The overall skeleton is built with M7.5 mortar rubble, and from top to bottom, there are mortar rubble slope protection with a top width of 0.45m; a drain hole 4 with a diameter of 100mm; a built-in drain pipe 8 with a diameter of 75mm; a width of 1.1 m greening groove 6; diameter is 8cm, and depth is the grass planting hole of 10cm; 2cm expansion joint 10; Length is 1.6m, and width is the rectangular anti-slide pile 1 of 1 meter; Described U-shaped drainage ditch 7 is the gathering place of current, The width is 0.8m, the depth is 0.7m, and the thickness is 0.3m.
[0035] Set 2cm expansion joints 10 at intervals of 10m along the slope, and fill with asphalt waterproof material.
[0036] Rectangular anti-sliding pile 1 can be made by manual or mechanical drilling, and is built by adding steel bars to concrete. The steel bars are arranged in the form of stirrup bars 3 and longitudinal bars 2. One is arranged at a height of 15 centimeters, and the stressed longitudinal r...

The invention relates to a slip-resistant pile and greening strip combined grouted rubble road slope protection structure. The grouted rubble road slope protection structure is characterized in that slip-resistant piles poured by concrete are arranged at the lower half part in a protection slope, and the slip-resistant piles are equidistantly arranged in the length direction of the protection slope; a slope protection surface formed by piling up mortar rubble is arranged on the inclined surface of the protection slope, greening grooves are formed in the slope protection surface, sandy soil isarranged in the greening grooves, and vegetation is planted in the greening grooves; and a plurality of drain holes are formed in the length direction of the protection slope in a staggered mode, andplastic drain pipes are placed in the drain holes. According to the structure, the protection slope is reinforced through the mortar rubble and the slip-resistant piles, the phenomenon that the stability of an existing side slope is poor is relieved, meanwhile, the comprehensive function of integrating supporting, protecting and greening is achieved, and the effects of reinforcing the side slope and beautifying the environment are achieved.
Description
technical field [0001] The invention relates to a slope protection structure for masonry rubble roads combined with anti-sliding piles and green strips, which is suitable for protection of cut slopes of easily weathered or severely weathered soft rocks or relatively broken rocks, and belongs to the protection of side slopes on both sides of roads construction field. Background technique [0002] Rectangular anti-slide piles are inserted into the stable strata below the sliding surface to generate resistance, resist the sliding thrust of the sliding body, increase its stability, and make the sliding body in front of the pile reach a stable state. Mortar rubble slope protection has the advantages of simple structure and obvious protective effect, but the hard covering of mortar rubble is not conducive to vegetation growth. In recent years, with the rapid development of expressways, the strength of rock and soil on slopes has decreased due to rain erosion, resulting in a decre...
