Abstract
The utility model discloses an embankment made of red sandstone filler. The cross section of the embankment is in a shell-core structure, the embankment core is made of red sandstone filler, the embankment shell is made of clay and is taken as the water-proof sealing layer, and the pavement is a waterproof layer; the slope protection structure comprises a baffle wall, an inverted filter layer, a concrete arc-shaped frame, and a water storage channel; a water inlet is arranged in the baffle wall body, the inverted filter layer is arranged in the water inlet, and the water storage channel is arranged in the concrete arc-shaped frame; the water drainage structure comprises a side channel, the water storage channel, and a drainage channel, wherein the water storage channel is arranged in the concrete arc-shaped frame. The embankment made of red sandstone filler is developed by improving the cross section structure, the slope protection structure and the drainage structure of conventional embankment structures. The problems of discharging water on the pavement and protecting the roadbed are effectively solved, the phenomenon that the red sandstone is degraded and deteriorated by water is effectively inhibited, and at the same time the long-term stability of the red sand stone embankment is guaranteed.
Description
Technical field
The utility model belongs to embankment design and construction field, relates in particular to a kind of Red Sandstone filler embankment.
Background technology
Red Sandstone refers to the deposition such as shale or arenaceous shale rocks, wherein most because being rich in, the oxide of iron takes on a red color, peony or brown, after excavation, As time goes on, easy disintegrating under the effect of atmosphere, sunlight, particularly rainwater, this rocks claims Red Sandstone, extensively exists Red Sandstone at Southwestern China and provinces and regions, the middle and south.At present, the fill section structure of Red Sandstone filler is mainly three kinds: linear pattern, fold-line-shaped and platform-type.
But, Red Sandstone railway embankment using is not that the cubic meter of stone in pure meaning fills, can not guarantee the long-time stability of this type of embankment according to common fill section structure design construction, Red Sandstone is met water easy disintegrating and expansion, easily loose after fragmentation, existing Red Sandstone filler embankment design can not effectively solve the surface drainage of Red Sandstone filler embankment, subgrade protection problem.
Utility model content
The purpose of this utility model is to provide a kind of Red Sandstone filler embankment, is intended to solve existing Red Sandstone filler embankment and can not guarantees the long-time stability of embankment, can not effectively solve the problem of surface drainage, subgrade protection.
Necessary technology scheme
The utility model is achieved in that a kind of Red Sandstone filler embankment comprises section structure, slope protection structure, discharge structure.Section structure comprises the dike heart, outsourcing soil layer, road surface, and section structure adopts outer-enwraped type embankment design form, adopts Red Sandstone filler, surrounding layer to adopt soil as water proof confining bed at dike heart position, and road surface adopts impervious blanket; Slope protection structure comprises barricade, loaded filter, concrete arch form skeleton and ponding ditch, on barricade body of wall, is provided with water inlet, and water inlet arranges loaded filter, is provided with ponding ditch in concrete arched framework; Discharge structure comprises gutter, ponding ditch and gutter, and ponding ditch is arranged in concrete arched framework.
Further, the liquid limit of surrounding layer soil is less than 50%, index of plasticity is greater than 6%, is less than 26%, CBR value and is greater than 3%;
Further, top thickness should be greater than 0.3m, and side should be greater than 1m;
Further, more than the long-term ponding of groundwater table or earth's surface position 500mm should be left in Red Sandstone filler embankment bottom, otherwise separation layer should be set, separation layer thickness should not be less than 300mm, and separation layer horizontal wall inscription should not be less than 4%;
Further, gutter is arranged on top one example of hillside embankment, or the both sides of flat site light fill;
Further, the general employing of the cross-sectional form in gutter is trapezoidal or dish-shaped, and size should be calculated and determine through the water conservancy hydrology, but bottom width and the degree of depth all should be not less than 0.5m, the sidewall gradient desirable 1: 1-1: 1.5.
A kind of Red Sandstone filler embankment that the utility model provides, improve by the section structure to traditional embankment structure, slope protection structure and discharge structure, efficiently solve the problem of surface drainage, subgrade protection, effectively reduce Red Sandstone and meet water disintegration degradation phenomena, can guarantee the long-time stability of Red Sandstone filler embankment simultaneously.
Accompanying drawing explanation
