Abstract

The utility model discloses a carbon mudstone-clay layered and staggered embankment filling structure composed of carbon mudstone (2) and clay (3) filled in layered and staggered modes. A clay layer (3) is arranged at the top, bottom and on two sides of the staggeredly filled embankment, drain pipes (5) are arranged on two sides of the clay layers (3), and a watertight pavement structure(4)is arranged on the top clay layer (3). The embankment filling structure has the advantages that the inside of the embankment is in a dry state for a long term, disintegration and softening of the carbon mudstone when meeting with water during a filled process for the embankment are avoided, and long-term stability of the carbon mudstone embankment structure is guaranteed.

Description

The staggered embankment of a kind of carbonaceous mud stone-native layering fills structure
Technical field
The utility model relates to a kind of carbonaceous mud stone embankment structure; Particularly relate to the staggered embankment of a kind of carbonaceous mud stone-native layering and fill structure; This embankment structure can make carbonaceous mud stone embankment inside keep dry state for a long time; Avoid the carbonaceous mud stone in as the embankment fill material process, to meet the water disintegration and soften, guarantee the long-term safety of carbonaceous mud stone embankment structure.
Background technology
The carbonaceous mud stone is distributed widely in area, China west and south; Because rational strong, the easy-weathering of its water, intensity is low, distortion is big; As embankment fill material the time, often cause following problem: the embankment with the carbonaceous mud stone fills is met the resistance to overturning reduction that water can make embankment, even the phenomenon that roadbed subsidence occurs, cave in.The bad filler of Chang Zuowei is discarded in highway construction in the past; But fast development along with China's expressway construction; The suitable filler in a lot of areas is very deficient; Consider from economy and environmental protection two aspects, utilize the carbonaceous mud stone to carry out embankment and fill imperatively, how to guarantee that the engineering safety of carbonaceous mud stone embankment in work progress and after building up is one of current key issue that needs to solve.Can test shows the key of filling that is used for embankment that the carbonaceous mud stone can success, be the drying that during highway operation, keep embankment structure inside.
The utility model content
The utility model technical problem to be solved provides a kind of embankment inside that keeps and is in dry state for a long time; Guarantee that carbonaceous mud stone embankment fill material is in good drying all the time and holds the power state during the road operation; Give full play to the advantage of carbonaceous mud stone filler self, the staggered embankment of workable carbonaceous mud stone-native layering fills structure.
In order to solve the problems of the technologies described above; The staggered embankment of the carbonaceous mud stone that the utility model provides-native layering fills structure; The staggered composition embankment that fills of carbonaceous mud stone and clay layering; Both sides, top and bottom at described embankment are provided with argillic horizon, on the described argillic horizon in both sides, are provided with gutter, above the described argillic horizon of the top one deck, are equipped with the waterproof pavement structure.
The thickness of the described argillic horizon of described embankment both sides is 40cm; The thickness of the described argillic horizon of the bottom of described embankment is 30cm; The thickness of the described argillic horizon at the top of described embankment is 20cm, and the thickness of clay soil between described carbonaceous mud stone and the described carbonaceous mud stone is 20cm.
The thickness of every layer of described carbonaceous mud stone is 50cm.
Described gutter is soft gutter.
Adopt the carbonaceous mud stone embankment structure of technique scheme; The little argillic horizon 40cm of water permeability is laid in the both sides of embankment; And lay the rainwater that soft gutter will infiltrate the both sides side slope and in time discharge, it is inner to stop the moisture diffusion effect through the both sides side slope of rainfall infiltration and rainwater to get into carbonaceous mud stone embankment.Lay the little argillic horizon 30cm of water permeability between carbonaceous mud stone and the ground; The embankment layer migration that can avoid the moisture in the foundation soil that capillarity causes to fill to the carbonaceous mud stone; Guarantee carbonaceous mud stone embankment fill layer and can not meet water softening after intensity reduce, the road surface adopts fine and close impermeable material to lay, and is provided with the crown slope of 2%-3%; Guarantee surface drainage, guarantee the long-term safety of carbonaceous mud stone embankment structure.
In sum; The utility model is to fill through the layering of carbonaceous mud stone and clay is staggered; Between ground and the carbonaceous mud stone, all lay the little clay of water permeability between the both sides of embankment and road surface and the carbonaceous mud stone and can effectively stop the extraneous moisture embankment inside of moving into; The road surfacing impermeable material is in time discharged rainwater through the 2%-3% crown slope from the road surface.Therefore the utility model can keep the long-term drying after the construction of carbonaceous mud stone embankment is accomplished stable, avoids the disintegration of carbonaceous mud stone chance water softening, fills a kind of feasible construction technology method that provides for the carbonaceous mud stone is used for embankment.
The utility model combines to carry out the staggered railway embankment using structure of layering with the carbonaceous mud stone with clay; Use fluid-tight road structure simultaneously; Improve infiltration draining and anti-drainage facility; It is inner to avoid water translocation to get into embankment, guarantees that carbonaceous mud stone embankment inside can be in good drying for a long time and hold the power state.
Description of drawings
The structural representation that Fig. 1 fills for the staggered embankment of the utility model carbonaceous mud stone layering.
The specific embodiment
Below in conjunction with accompanying drawing, specify the staggered carbonaceous mud stone embankment structure that fills of a kind of layering.
Referring to Fig. 1; Carbonaceous mud stone 2 is formed embankment 7 with staggered the filling of clay 3 layerings on roadbed 1, and the thickness of carbonaceous mud stone 2 is 50cm, is provided with the little argillic horizon of water permeability 6 in both sides, top and the bottom of embankment 7; On the argillic horizon 6 of the both sides of embankment 7, be provided with soft gutter 5; The thickness of the argillic horizon 6 of embankment 7 both sides is 40cm, and the thickness of the argillic horizon 6 of the bottom of embankment 7 is 30cm, and the thickness of the argillic horizon 6 at the top of embankment 7 is 20cm; Thickness of clay soil between carbonaceous mud stone 2 and the carbonaceous mud stone 2 is 20cm, above the argillic horizon 6 of the top one deck, is equipped with waterproof pavement structure 4.
As shown in Figure 1; When laying is filled; Through after the smooth compacting, following 1.7m, 0.9m, 0.2m degree of depth place fill 30cm, 20cm, clay that 20cm is thick respectively in the bottom surface, road surface, and the thick carbonaceous mud stone 2 of 50cm is filled at following 1.4m, 0.7m degree of depth place in the bottom surface, road surface; Fill thick clay of 40cm and fully compacting simultaneously in both sides, lay waterproof pavement structure 4 again on top.
