Abstract

A novel inter-embedded type soil retaining building block comprises a building block body (1), wherein four small holes (2) and a large hole (3) are formed in the front edge of the building block body (1), the four small holes (2) are used for inserting rubber rods (7), two sides of the building block environmental protection property body (1) are recessed downwards to form a groove (4), the middle of the building block body (1) is protruded upwards to form a protrusion (6), and a rear edge large hole (5) is formed in the protrusion (6). The novel inter-embedded type soil retaining building block has the advantages that a module is of a protrusion-recession structure, so that a retaining wall can be prevented from sideward deforming; meanwhile, friction forces among the modules in front and back directions are also increased, so that the retaining wall can be prevented from backward deforming; the front edges of the modules are planar, and the rear edges of the modules are staggered in a convex-concave mode, so that attractiveness can be improved, and meanwhile, an inclined retaining wall, an inward concave arc retaining wall and an outward concave arc retaining wall can be built; the large hole is formed in the front edge of the module, and the hole is formed in the protruded portion of the rear edge, so that module weight can be reduced, rubbles and soil mass can be added to the module, and environmental protection property and shear-bearing capacity are improved.

Description

Novel inter-embedding type gear earth building blocks

Technical field

The utility model relates to slope construction technical field, specifically a kind of novel inter-embedding type gear earth building blocks.

Background technology

In geotechnical engineering, the application of retaining wall has quite long history, and it is mainly for resisting the effect of soil pressure, preventing slope slide instability.Gear earth building blocks, as a kind of new structure of retaining wall, has irreplaceable effect in side slope.Traditional gear earth building blocks, has played the native effect of good gear, but has often ignored such as flexible, attractive in appearance, easy construction and the value such as more economically.

Summary of the invention

The purpose of this utility model is that a kind of can being used in of design kept off in native side slope, not only firm, attractive in appearance, and constructability, simultaneously also economical, is convenient to the novel inter-embedding type gear earth building blocks of transportation.

A kind of novel inter-embedding type gear earth building blocks of the utility model, comprising: building block, and building block leading edge has four apertures and a macropore, four apertures are used for inserting rubber bar, and building block both sides, to lower recess, form groove, building block middle part is protruding upward, forms projection, has a trailing edge macropore in projection;

Described macropore can alleviate module weight, during construction, at it, adds graded broken stone, can connect with upper strata back porch concave arc, increases module contact surface shear strength;

In described aperture, inserting rubber bar can stationary grizzly, increases shear strength, improves crashworthiness, makes between block, to form up and down a flexible integral; When being built into straight line wall, rubber bar inserts inner aperture; While being built into curved wall, rubber bar inserts outer aperture;

A kind of novel inter-embedding type gear earth building blocks of the utility model is achieved in that

1., when assembling barricade, module is had to facing up of outstanding-depression, flat one is sidelong and puts substrate, the tight adjoint laying of a row; The second layer need to embed lower floor's sunk part by ledge by module turn-over, by this arrangement, lays, and the two-layer of so mutual embedding just completes; Upper strata then need to, by the sequence of positions discharge of first floor, spread such one deck and embed lower one deck thereon again;

2., geo-grid should be laid on the contact surface of module flat, inserts rubber bar after laying in hole, rubber bar runs through bilevel aperture and grid aperture, fixing upper and lower building block and grid; If panel needs to tilt, the certain distance that staggers on can be longitudinally, at this moment rubber bar can pass through aperture, leading edge macropore and grid aperture, with stationary grizzly;

3., by horizontal plane to the certain angle that staggers between two modules, can assemble into inner arc barricade and outer arc barricade, rubber bar can pass through outer two aperture stationary grizzlies.

The advantage of a kind of novel inter-embedding type gear earth building blocks of the utility model is: module adopts outstanding---sunk structure, can prevent barricade lateral deformation, and also increase the frictional force on intermodule fore-and-aft direction simultaneously, after prevention barricade wall, be out of shape; Module leading edge plane trailing edge convex-concave is staggered, not only can increase attractive in appearancely, can assemble into inclination barricade, imploded arcs barricade and outer convex arc barricade simultaneously; Module leading edge has a macroscopic void, and trailing edge ledge has a hole, not only can alleviate module weight, and can add therein rubble and the soil body, increases its feature of environmental protection and shear resistance.

The specific embodiment

Shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4: a kind of novel inter-embedding type gear earth building blocks, comprise: building block 1, building block 1 leading edge has four apertures 2 and a macropore 3, four apertures 2 are used for inserting rubber bar 7, building block 1 both sides, to lower recess, form groove 4, and building block 1 middle part is protruding upward, form projection 6, trailing edge macropore 5 of projection 6 interior existence;

Described macropore 3 can alleviate module weight, during construction, at it, adds graded broken stone, can connect with upper strata back porch concave arc, increases module contact surface shear strength;

2 li of described apertures insert rubber bars 7 can stationary grizzly, increases shear strength, improves crashworthiness, makes between block, to form up and down a flexible integral; When being built into straight line wall, rubber bar 7 inserts inner aperture; While being built into curved wall, rubber bar 7 inserts outer aperture.

Claims

1. a novel inter-embedding type keeps off earth building blocks, it is characterized in that: comprising: building block (1), building block (1) leading edge has four apertures (2) and a macropore (3), four apertures (2) are used for inserting rubber bar (7), building block (1) both sides, to lower recess, form groove (4), and building block (1) middle part is protruding upward, form projection (6), in projection (6), have a trailing edge macropore (5).
