Abstract
The utility model provides a half cut and fill stone roadbed structure, the roadbed fill side is equipped with multistage step, the concrete prefabricated section of full spread rectangle on every step, prefabricated section lateral surface on the higher level step flushes with the prefabricated section lateral surface on the subordinate step, the prefabricated section top surface on the upper level step flushes with excavation side road bed top surface, every prefabricated section transversely wears to establish two piece at least stock along the road bed, stock one end is deepened in the mountain of excavation side, other end anchor is in the outside of prefabricated section. The utility model discloses utilizing the massif to provide anchor power with the prefabricated section anchor, forming the rigidity road bed, need not to roll and can carry out the road surface construction, construction speed is fast, and the expense is low, and roadbed structure is stable, is particularly useful for filling the little office of volume and digs and do and fill out the road bed construction.
Description
Technical Field
The utility model belongs to the technical field of the road construction, when relating to mountain highway construction, a structure of partly digging half fill stone road bed.
Background
When the road construction is carried out in the mountain area with the stone structure, the construction is sometimes limited by natural conditions such as terrain, geology and the like, the road is built along a hillside, one side of a roadbed close to a mountain body needs to be excavated, the other side needs to be filled, and the excavation and filling construction is carried out. The stability of the semi-excavated and semi-filled roadbed at the filling side is the key for ensuring the safe passing of vehicles, and generally, a gravity type retaining wall is built firstly to be used as a retaining structure at the filling side, and then filling construction is carried out.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a with low costs, construction speed is fast and is dug half fill stone roadbed structure and construction method to the less half fill stone roadbed of digging half of fill.
The utility model provides a pair of half fill stone roadbed structure digs, the road bed is built along the massif, and one side is the excavation structure, and the opposite side is fill structure, its characterized in that: the roadbed filling side is provided with a plurality of steps along a mountain body, each step is fully paved with rectangular concrete precast blocks, the outer side surface of a precast block on the upper step is flush with the outer side surface of a precast block on the lower step, the top surface of a precast block on the uppermost step is flush with the top surface of a roadbed on the excavation side, each precast block transversely penetrates through at least two anchor rods along the roadbed, one end of each anchor rod penetrates into the mountain body on the excavation side, and the other end of each anchor rod is anchored on the outer side of the precast block; and paving road surface layers on the excavation side roadbed and the filling side roadbed.
The utility model discloses make full use of original massif topography and geological conditions, open the step on one side road bed that needs fill, lay the prefabricated section on the step, utilize the massif to provide anchor power with the prefabricated section anchor, form the rigidity road bed, need not to roll and can carry out the road surface construction, construction speed is fast, and the construction input is few, and the expense is low, and road bed stable in structure can guarantee the road traffic safety, is particularly useful for filling the little office of volume and digs and do and fill out the road bed construction.

FIG. 3 is a schematic view of a stepped structure excavated on the side of a roadbed fill;
FIG. 4 is a schematic view showing a state where a precast block is installed on a filling side step.
Detailed Description
As shown in fig. 1 and fig. 2, the roadbed is constructed along the mountain 1, one side of the roadbed is a cut-out structure, and the other side of the roadbed is a fill structure; the roadbed filling side is provided with a plurality of steps along a mountain body, each step is fully paved with a rectangular concrete precast block 2, the outer side surface of the precast block on the upper step is flush with the outer side surface of the precast block on the lower step, the top surface of the precast block on the uppermost step is flush with the top surface of the roadbed on the excavation side, each precast block transversely penetrates through at least two anchor rods 3 along the roadbed, one end of each anchor rod 3 extends into the mountain body 1 on the excavation side, and the other end of each anchor rod is anchored on the outer side of the precast block; and paving a road surface layer 4 on the excavation side roadbed and the filling side roadbed.
The concrete construction method of the half-excavated half-filled stone roadbed comprises the following steps:
(1) as shown in fig. 3, the excavation side 5 of the roadbed is excavated to the designed elevation along the mountain body; building multiple steps 6 along the mountain 1 at the filling side of the roadbed, and drilling a row of anchor holes 7 in the mountain at the excavation side along the roadbed lateral direction at the outer side of each step 6;
(2) prefabricating a plurality of rectangular concrete precast blocks 2, and transversely reserving at least two anchor holes on each precast block according to the distance between the anchor holes on the steps;
(3) as shown in fig. 4, the precast blocks 2 are fully paved on each step, the anchor hole of each precast block is aligned with the anchor hole on the side surface of the step, the outer side surface of the precast block of the upper step is flush with the outer side surface of the precast block of the lower step, and the top surface of the precast block at the topmost layer is flush with the top surface of the excavation side 5 of the roadbed;
(4) penetrating an anchor rod 3 into each anchor hole, grouting, and anchoring the exposed end of the anchor rod on the outer side surface of the precast block by using an anchorage device;
(5) and paving road surface layers 4 on the top surfaces of the excavation side 5 and the filling side uppermost precast blocks 2 of the roadbed.
