Description
Technical field
The utility model relates to a kind of concrete in mass retaining structure, belongs to engineering design technology field.
Background technology
Soil pressure after gravity highway retaining structure dependence body of wall deadweight resistance wall, press design section by mortar flag stone or stone block building, for tall and big gravity structure, (gear is highly greater than 10m, section minimum dimension is greater than 1m), due to body of wall bulky, the carrying of material in work progress, block slabstone in place, build by laying bricks or stones, the scene such as label, match ratio of masonry mortar is difficult to accurate control, and can these factors are directly connected to masonry quality reach technical requirement on design.Retaining structure in use, often occur the early disease such as deformation of wall, bulge, displacement, cracking because the factors such as building materials, masonry quality, construction method, maintenance are improper, cave in, and causes certain potential safety hazard to the normal use of highway by serious causing.Improve supporting and protection structure quality targetedly, ensure subgrade stability, there is realistic meaning.
Utility model content
For solving the technical problem of body of wall that prior art exists in use yielding, bulge, displacement, cracking, it is simple that the utility model provides a kind of structure, adopt cast-in-place concrete, body of wall is firm, the concrete in mass retaining structure that safety factor is high.
For achieving the above object, the technical scheme that the utility model adopts is a kind of concrete in mass retaining structure, comprising: retaining wall body, and described retaining wall body is formed by concreting, is also provided with anticracking steel mesh reinforcement in retaining wall body
,and being provided with multilayer cooling water pipe from top to bottom in retaining wall body, the cooling water pipe of every layer is snakelike layout, and described retaining wall body is provided with pre-joint-cutting and settlement joint.
Preferably, the spacing distance of described settlement joint is 10m, and the spacing distance of pre-joint-cutting is 5m, and the seam of pre-joint-cutting is 10-20mm deeply, and stitching wide is 5mm.
Preferably, described cooling water pipe or be cast iron pipe, or be polyethylene pipe.
Preferably, described retaining wall body is also provided with slabstone.
Compared with prior art, the utility model has following technique effect: the utility model adopts the mode of concrete cast in situs, construction technology is simple, speed of application is fast, quality is easy to control, the consumption such as a large amount of artificial, material can be saved, can ensure that retaining structure has higher cross section resistance to compression, shear strength simultaneously, and formed overall with basis, the effect of soil body lateral pressure and roadbed overhead vehicle load after shared wall, meet subgrade stability and structure durability requirement, improve traffic safety performance, realize the highway long-life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is section structure schematic diagram of the present utility model.
Detailed description of the invention
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As Fig. 1, shown in Fig. 2, a kind of concrete in mass retaining structure, comprise: retaining wall body 1, described retaining wall body 1 is formed by concreting, anticracking steel mesh reinforcement 5 is also provided with in retaining wall body 1, and be provided with multilayer cooling water pipe 2 from top to bottom in retaining wall body 1, the cooling water pipe 2 of every layer is in snakelike layout, described retaining wall body 1 is provided with pre-joint-cutting 3 and settlement joint 4, the spacing distance of settlement joint 4 is 10m, the spacing distance of pre-joint-cutting 3 is 5m, and the seam of pre-joint-cutting 3 is 10-20mm deeply, stitching wide is 5mm, cooling water pipe 2 or be cast iron pipe, or be polyethylene pipe, described retaining wall body 1 is also provided with slabstone.
More specifically, retaining wall body adopts cast-in-place more than C20 concrete to replace traditional masonry (cemented rock, mortar flag stone) structure, and inside concrete can add the slabstone being not more than 25%, improves mechanical performance of concrete, saves cement consumption; Concrete has good workability and service behaviour, and the slump is not more than 150mm.Mixing water content should not be greater than 175kg/m
3, design grade is not less than C20.Construction technology is simple, and speed of application is fast, and quality is easy to control, and can save the consumption such as a large amount of artificial, material.
Arrange anticracking steel mesh reinforcement in retaining wall body, anticracking steel mesh reinforcement, primarily of along retaining wall body longitudinally configuration ￠ 8-￠ 10 horizontal reinforcement, is born thermal stresses and the shrinkage stress of inside concrete generation, is improved concrete ultimate tensile strength; Vertically arrange ￠ 8-￠ 10 reinforcing bar, spacing 100-150mm, arrange along wall outer side and inner surface, its gradient is carried on the back consistent with metope, wall, and the clean topping of reinforcing bar is not less than 50mm.
The retaining wall body sectional form as calculated all more former masonry of the retaining structure metope gradient, wall back slope degree and cross dimensions reduces to some extent, small volume.Simultaneously can also be designed to different types, more be conducive to structure stress and mechanics is stablized.According to body of wall height, section can be designed to stepped ramp type or overall section.
Retaining wall body establishes settlement joint along the every 10m in path length direction, is convenient to deformation of wall and coordinates, every 5m along wall top, metope establishes pre-joint-cutting together, in order to replace the mixed and disorderly spontaneous crack of concrete.Stitching dark 10-20mm, stitch wide 5mm, arranging, for discharging walls concrete shrinkage strain along short transverse.Overall stratified continuous pouring is adopted to construct when building.In a settlement joint paragraph, increase wall location front size, improve the stabilizing moment that vertical force produces, diffusion foundation stress.
In addition, adopt external diameter 25 mm cast iron pipe or external diameter 32 mm polyethylene pipe as cooling water pipe, the timely water filling cooling provision when concrete starts to build, reduce the heat of hydration produced in concreting process.Before concreting, water pipe is laid on leveling course, vertical interval 1.5-2m, level interval 0.75-1.0m, the snakelike layout of horizontal direction, vertical direction horizontal arrangement.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should wrap within the scope of the utility model.
