Description

A kind of retaining wall block and retaining wall

Technical field

The utility model relate to a kind of auto-buckled type from draining, self catcher soil, the ecological retaining wall block of overturning or slip resistance analysis, also be a kind of retaining wall block that combines with reinforced geo-grid and geotechnological anchor pole, also relate to a kind of retaining wall by this retaining wall block bond.

Background technology

In the last few years, the bank protection in tradition river course and barricade adopt the stiff materials of the function singleness protection such as concrete, piece stone class mostly, make whole river cross-section uniform, surface-closed is stiff, completely cut off the mass exchange between soil and the water body, the biology that originally was grown on the bank slope can not be survived, the food chain of the ecosystem disconnects, make the biology in the soil and water lose the environment of depending on for existence, make originally the vivifying river course power that loses one's life, river is smelly, and spot is full of stains or spots, becomes to destroy ecological main chief-criminal.

At present, reinforcement formula retaining wall block shape is various, wherein, connect concrete block because of simple in structure from the embedded anchoring rods, easy construction and welcome by part, but when backfill is born larger soil pressure and load behind wall, the basis with the muscle material to its restraint forces a little less than, it is poor that tension is dialled power, resistance to deformation and resistance to settling, the deformation of wall outer incline easily occurs and the destruction of caving in, and the river course when using ecological diversity very poor.

Reinforced soil retaining wall behind soil pressure and the load force of back filled region is mainly born by reinforcement material, as Chinese invention patent number be 200410071516.1, name is called the patented technology of " permeable soil keeping wall and uses thereof ", wherein building block is main only for preventing water leakage and lateral force resistance, does not consider for the combination of building block and reinforcement material is more; As Chinese invention patent number be 200810027182.6, name is called " a kind of building block that can build the stacked formation multifunctional wall body of mutual kayser by laying bricks or stones " and Chinese invention patent number are called " building block of a kind of rectangle like abnormity shape " for 200720156998.X, name patented technology, wherein building block only considers to be stacked to wall, do not consider that lateral force is stable, do not consider and being combined with of reinforcement material yet, have various potential safety hazards; Number be ZL200920141099.1 such as practical new patent, the patented technology that name is called " a kind of retaining wall block of being combined with reinforcement material " had not only been considered lateral stability but also had been considered combination with reinforcement material, but when backfill behind the wall is born larger soil pressure and load, reinforcement material is combined good not with building block, reinforcement material easily gets loose, walling unit easily is out of shape perk, cause body of wall to destroy, also have, when retaining wall block under without the excavation construction condition, need geotechnologically when anchor rod anchored, its building block is difficult to good anchoring, and therefore retaining wall loses effective tractive, there is potential safety hazard in easy whole unstable failure.
