Abstract
The utility model belongs to the technical field of transportation and communication engineering, particularly relates to the technical field of highway subgrade retaining walls, further relates to a horseshoe pre-cast block-type wall board structure used in reinforced earth retaining walls, and aims to overcome the problems in the prior art that the transportation is inconvenient and the difficulty in construction is great. To overcome the problems associated with the prior art, the utility model adopts the technical scheme that the wall board structure comprises a plurality of pre-cast blocks; and the pre-cast blocks taking the shape of a horseshoe are mutually overlapped in a staggered manner. Compared with the prior art, the utility model has the advantages of convenient carrying and construction, good construction effect, strong suitability of the integral molding, and multiple functions.
Description
Technical field
The utility model belongs to the Communication and Transportation Engineering technical field, is specifically related to highway subgrade retaining wall technical field, further relates to a kind of shape of a hoof reinforced earth retaining wall prefabricated section formula shingle nail structure.
Background technology
Retaining wall is meant and is used for supporting that roadbed bankets or the hillside soil body, prevents to banket or the structure of soil deformation unstability.In subgrade construction, retaining wall can reduce earth and rock works amount and floor space in order to stable road bed and cut slope, prevents the current scour roadbed, and through being usually used in subgrade defects such as regulation landslide, landslide.Form of structure according to retaining wall is divided, and common retaining wall form has: gravity, weight formula, cantilevered, counterfort formula, reinforced earth formula, anchor rod type and grappling are board-like, also has vertical prestressed anchor rod-type, soil nailing formula and stake board-like in addition.
Reinforced earth retaining wall is a kind of supporting construction that utilizes reinforced earth technology to build.Reinforced earth is a kind of composite earth that adds lacing wire in soil, and it utilizes the rubbing action between lacing wire and the soil, improves the deformation condition of the soil body and the engineering property of the raising soil body, thereby reaches the purpose of stablizing the soil body.Reinforced earth retaining wall is made up of filler, the lacing wire of arranging in filler and shingle nail three parts.The effect of shingle nail is that the side direction that prevents to banket is extruded, transmitted soil pressure and is convenient to that lacing wire is fixing lays, and guarantees that filler, lacing wire and metope constitute the integral body with definite shape.Shingle nail not only will have certain intensity to guarantee the stable of the lacing wire end soil body; And require to have enough rigidity, with the impact and the shock effect of opposing expection; Should have enough flexibilities again, to adapt to the distortion that permissible settlement was brought that reinforced earth produces under load action.Domestic concrete commonly used or steel concrete shingle nail, type have cross, flute profile, hexagon, L shaped, rectangle and arc etc., and the problem of its existence is: 1, transportation is inconvenient: because the shingle nail size is bigger and heavy, and therefore bad carrying; 2, difficulty of construction is big: because self no self-stable ability needs a retaining in the construction, simultaneously for adapt to the top and and the structure requirement at corner place, also need special-shaped panel and the corner plate of design separately, so complicated operation, constructional difficulties.
Summary of the invention
The purpose of this utility model provides a kind of shape of a hoof reinforced earth retaining wall with prefabricated section formula shingle nail structure, to overcome the inconvenient and big problem of difficulty of construction of prior art transportation.
For overcoming the problem that prior art exists, the technical solution of the utility model is: a kind of shape of a hoof reinforced earth retaining wall comprises the prefabricated section of a plurality of interlaced overlap joints with prefabricated section formula shingle nail structure, and described prefabricated section is the shape of a hoof.
Compared with prior art, the utility model has the advantages that:
(1) convenient in carrying: because size is less, so just reduced handling workload, reduced the requirement of building by laying bricks or stones simultaneously to on-the-spot place.
(2) easy construction: the shape of a hoof prefabricated section self stability of forming shingle nail is good, does not need a retaining in construction; Owing to have good non-deformability, therefore can adapt to the structure requirement at top and corner place, do not need to do particular processing.
(3) construction effect is good: the compliance of the distortion that permissible settlement brought that the reinforced earth in the packing layer is produced under load action is strong.
(4) moulded compliance is strong: the shape of a hoof prefabricated section of forming shingle nail not only can be built the plane body of wall by laying bricks or stones, more can build out the waveform metope by laying bricks or stones.
(5) function is many: not only have the basic function of retaining wall, because of existing bigger gap between the prefabricated section, therefore can afforest simultaneously, form three-dimensional view.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is to use schematic diagram.
Description of reference numerals is as follows:
The 1-prefabricated section, 2-filler, 3-lacing wire.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is described.
Referring to Fig. 1, a kind of shape of a hoof reinforced earth retaining wall comprises the prefabricated section 1 of a plurality of interlaced overlap joints with prefabricated section formula shingle nail structure, and described prefabricated section 1 is the shape of a hoof.
Referring to Fig. 2, in the use, shingle nail that the utility model provides and the filler 2 that is furnished with lacing wire 3 form reinforced earth retaining wall.
Claims (1)
1. a shape of a hoof reinforced earth retaining wall comprises the prefabricated section (1) of a plurality of interlaced overlap joints with prefabricated section formula shingle nail structure, and described prefabricated section (1) is the shape of a hoof.
