Abstract
The utility model discloses a kind of reinforced bar net layered rolling retaining wall structure, this structure comprises the reinforced concrete foundation located below ground level, reinforced concrete foundation is provided with the reinforced bar net layered rolling retaining wall body of wall be made up of building block, body of wall top is provided with steel concrete cap stone, and exterior surface of wall is provided with surface layer; Be equipped with the grid that layering is arranged inside body of wall, between grid, be provided with the backfill of layering compaction by rolling.The utility model have employed different wall body structures according to the height difference of retaining wall, has both met the requirement of bearing capacity of foundation soil, has eliminated potential safety hazard, also saved the construction investment of operating surface simultaneously, shorten the construction period; The utility model is rational in infrastructure, clearly stressed.
Description
Technical field
the utility model relates to a kind of reinforced bar net layered rolling retaining wall structure, and what belong to decomposition operating surface constructs technical field.
Background technology
according to the technological process requirement of decomposition, need structure length L to be 300 meters, width W is 42 meters, and the gradient is the operating surface of 3%.Constructing of this operating surface first constructs retaining wall, formation of then banketing in retaining wall, and therefore this operating surface is a long and narrow inclined plane, and minimum operating surface is concordant with ground, and operating surface highest point H is above the ground level about 9 meters.Existing retaining wall all adopts steel concrete cantilever retaining wall.This structure has the following disadvantages, when basis hold power bearing capacity lower or for backfill time, higher steel concrete cantilever retaining wall bearing capacity of foundation soil can not meet the demands, and there is potential safety hazard.The steel concrete cantilever retaining wall construction period is longer in addition, invests larger.
Utility model content
the purpose of this utility model is, provides a kind of and can eliminate safe hidden trouble and the reinforced bar net layered rolling retaining wall structure that the construction period is shorter, investment is less, to overcome the deficiencies in the prior art.
the technical solution of the utility model is achieved in that
a kind of reinforced bar net layered rolling retaining wall structure of the present utility model is, this structure comprises the reinforced concrete foundation located below ground level, reinforced concrete foundation is provided with the reinforced bar net layered rolling retaining wall body of wall be made up of building block, body of wall top is provided with steel concrete cap stone, and exterior surface of wall is provided with surface layer; Be equipped with the grid that layering is arranged inside body of wall, between grid, be provided with the backfill of layering compaction by rolling.
in aforementioned structure, described grid width W 1 is not less than 2 meters, and the spacing between every layer of grid is not less than 350mm.
owing to have employed technique scheme, the utility model compared with prior art, the utility model have employed different wall body structures according to the height difference of retaining wall, the utility model meets the requirement of bearing capacity of foundation soil by adopting reinforced bar net layered rolling structure at higher retaining wall, thus effectively eliminates potential safety hazard.The utility model had both met the requirement of bearing capacity of foundation soil, turn eliminated potential safety hazard, also saved the construction investment of operating surface simultaneously, shortened the construction period.Use through actual tests and prove, the utility model not only has the advantage that can effectively eliminate safe hidden trouble, but also has construction period short, less, rational in infrastructure, the stressed advantage such as clearly of investment.

being labeled as in accompanying drawing: the backfill of 1-reinforced bar net layered rolling retaining wall, 2-steel concrete cantilever retaining wall, 3-backfill, 4-ground, 5-grid, 6-reinforced concrete foundation, 7-reinforced concrete segment, 8-layering compaction by rolling, 9-surface layer, 10-steel concrete cap stone, 11-boundary.
Detailed description of the invention
below in conjunction with drawings and Examples, the utility model is described in further detail, but not as to any restriction of the present utility model.
the utility model is constructed by the construction method of following a kind of decomposition retaining wall, as shown in Figure 1, the method is 8 meters of punishment circles 11 in decomposition retaining wall height H, and retaining wall height H is less than 8 meters one section and still adopts existing steel concrete cantilever construction; Retaining wall height H is equal to or greater than one section of employing reinforced bar net layered rolling structure of 8 meters; Steel concrete cantilever construction adopts and first constructs retaining wall, then the construction method of backfill; Reinforced bar net layered rolling structure adopts builds one deck building block, lays one deck grid, the construction method that pad one deck backfill compaction by rolling successively raises.The construction sequence of reinforced bar net layered rolling retaining wall is first in below ground construction reinforced bar concrete foundation, reinforced concrete foundation is built one deck building block, lays one deck grid inside building block, grid pads one deck backfill compaction; Then repeat above-mentioned steps to build to design height always, last construct a steel concrete cap stone along most top layer block tops, and at building block external surface construction surface layer.Grid width is not less than 2 meters, and the spacing between every layer of grid is not less than 350mm, and the degree of compaction of layered rolling backfill is greater than 93%.
according to of the present utility model a kind of reinforced bar net layered rolling retaining wall structure that said method builds, as shown in Figure 3, this structure comprises the reinforced concrete foundation 6 being positioned at ground less than 4, reinforced concrete foundation 6 is provided with reinforced bar net layered rolling retaining wall 1 body of wall be made up of building block 7, body of wall top is provided with steel concrete cap stone 10, and exterior surface of wall is provided with surface layer 9; Be equipped with the grid 5 that layering is arranged inside body of wall, between grid 5, be provided with the backfill 8 of layering compaction by rolling.Grid 5 width W 1 is not less than 2 meters, and the spacing between every layer of grid is not less than 350mm.
Embodiment
as shown in Figure 1, when retaining wall is higher than 8 meters, and when bearing capacity of foundation soil is lower, decomposition DESIGN OF RETAINING WALLS is become reinforced bar net layered rolling retaining wall 1.To ensure the safety of structure, investment reduction and the reduction of erection time simultaneously.If when transforming existing decomposition retaining wall, boundary 11 can be set being highly about 8 meters of, remove the steel concrete cantilever retaining wall higher than 8 meters, again constructing by reinforced bar net layered rolling retaining wall 1.When constructing reinforced bar net layered rolling retaining wall 1, first do 1200 × 500mm reinforced concrete foundation 6; Spread the backfill 8 of one deck grid 5 and layering compaction by rolling again at interval of 350mm, then build 350 × 350 × 500mm reinforced concrete segment at reinforced concrete foundation 6 end face.Grid 5, backfill, building block 7 are alternately constructed until retaining wall top; Finally build 150mm thick C30 steel concrete surface layer 9 in reinforced bar net layered rolling retaining wall 1 side; Finally again do steel concrete cap stone 10 at surface layer top C25 concrete.
