Abstract
The utility model relates to a light-duty superelevation road bed side slope barricade structure, include the barricade basis and the wall body of pouring according to the road bed side slope, the wall body is kept away from slope body one side and is established the side fascia, and the end wall board is established respectively at the wall body both ends, and the baffle that the one deck level set up is established at every certain interval to side fascia and end wall board inboard, pours foam lightweight concrete between the adjacent baffle from top to bottom. The utility model discloses the structure dead weight is light, reduces the requirement to the ground bearing capacity, and the cost is low, and construction cycle is short.
Description
Technical Field
The utility model relates to a road construction technical field relates to when mountain area highway is built, sets up the barricade structure that prevents in the road bed or the side slope outside that the road bed is filled out soil or the side slope soil body warp unstability.
Background
In the process of mountain road construction, retaining walls are often arranged on the outer sides of steep subgrades or side slopes to prevent subgrade filling or side slope soil body from being unstable and collapsing. The existing retaining wall mostly adopts a gravity type structure, maintains roadbed filling or slope soil body stability by the self gravity of the retaining wall, generally adopts plain concrete, stone slab concrete and less-rib concrete pouring, or blocks, stones and concrete precast blocks for grouting, and has the advantages of available local materials and convenient construction.
The gravity type retaining wall has the advantages that the higher the height is, the larger the section size is, the larger the volume and the weight are, and the higher the requirement on the bearing capacity of the foundation is. For some retaining walls with the height of more than 15m, the construction on a soft foundation is often limited by the bearing capacity, and the existing solution is to add a pile foundation on the bottom of the retaining wall, but the construction cost is higher and the construction period is longer.
Disclosure of Invention
The utility model aims at the weak point that gravity type barricade exists, provide a light-duty barricade structure of subgrade side slope superelevation, under the prerequisite of guaranteeing that the barricade function satisfies the requirement, reduce barricade self gravity and require the foundation bearing capacity, practice thrift construction cost simultaneously.
The technical scheme of the utility model as follows:
the utility model provides a light-duty superelevation road bed side slope retaining wall structure, includes the retaining wall basis and according to the wall body that road bed side slope was pour, its characterized in that: the wall body is kept away from slope body one side and is established the side fascia, and the end wall board is established respectively at the wall body both ends, the baffle that the one deck level set up is established at every certain interval to side fascia and end wall board inboard, and wherein lower floor's baffle is pour on the barricade basis, and the superiors' baffle flushes with the slope body top surface, side fascia, end wall board and baffle all adopt reinforced concrete to pour, pour foam lightweight concrete between upper and lower adjacent baffle.
The retaining wall is divided into a plurality of layers by the partition plates, and the reinforced concrete plate structures are arranged on the upper and lower parts and the periphery of each layer to restrain the lateral and vertical deformation of the wall, so that each layer of the wall can adopt a foam light soil structure, the volume weight of the foam light soil is only one fourth of that of plain concrete, the self weight of the structure can be greatly reduced, and the requirement on the bearing capacity of a foundation is reduced; the price of the foamed lightweight soil per cubic meter is one half of that of concrete, so that the total construction cost is greatly reduced; the foam lightweight soil does not need to be vibrated when being poured, has good fluidity, can be remotely pumped, and can greatly shorten the construction period compared with the prior gravity type concrete wall body.

fig. 2 is a schematic view of the vertical structure along the direction of the slope body.
Detailed Description
As shown in fig. 1 and 2, the utility model discloses a retaining wall foundation 1 and a wall body poured according to roadbed side slope 7, the wall body is kept away from slope body one side and is established side fascia 2, and the end wall board 3 is established respectively at the wall body both ends, the side fascia 2 and the end wall board 3 inboard are established the baffle 4 that the one deck level set up at regular intervals, and wherein the baffle of the lower floor is poured on retaining wall foundation 1, and the baffle of the superiors is flushed with slope body 7 top surface, side fascia 2, end wall board 3 and baffle 4 all adopt reinforced concrete to pour, set up the two-way arrangement of reinforcement of bilayer; and foam lightweight concrete 5 is poured between the upper and lower adjacent partition plates.
The both ends of baffle 4 with keep away from mountain side and pour as an organic wholely with both ends wallboard 3 and 2 inboards of side fascia respectively, the orientation slope side of baffle is equipped with vertical anchor muscle 6 of implanting in slope body 7 to reinforcing wall body cling compound ability.
The retaining wall foundation can adopt a plain concrete or rubble concrete structure and is used for transmitting load born by the retaining wall and the self-weight of the structure to the foundation after diffusion.
The external wall panel and the end wall panel are used for restraining the lateral deformation of the wall body and dividing the wall body into a plurality of mutually independent layers together with the partition boards; the clapboard bears the vertical load of the upper part and ensures the uniformity of force transfer between layers; each layer of wall body between the partition boards is poured by adopting foamed light soil, so that the self weight of the wall body and the requirement on the bearing capacity of a foundation can be greatly reduced.
Claims (2)
1. The utility model provides a light-duty superelevation road bed side slope retaining wall structure, includes the retaining wall basis and according to the wall body that road bed side slope was pour, its characterized in that: the wall body is kept away from slope body one side and is established the side fascia, and the end wall board is established respectively at the wall body both ends, the baffle that the one deck level set up is established at every certain interval to side fascia and end wall board inboard, and wherein lower floor's baffle is pour on the barricade basis, and the superiors' baffle flushes with the slope body top surface, side fascia, end wall board and baffle all adopt reinforced concrete to pour, pour foam lightweight concrete between upper and lower adjacent baffle.
2. The lightweight ultra-high roadbed slope retaining wall structure as recited in claim 1, wherein: the both ends of baffle and keep away from mountain side and pour as an organic wholely with both ends wallboard and side fascia inboard respectively, the orientation slope side of baffle is equipped with the vertical anchor muscle of implanting in the slope body.
