Abstract

The utility model discloses a base pavement structure for squares, parking lots and garden roads, which comprises: a foundation bearing layer (6) composed of rammed earth; ; The graded crushed stone layer (4) arranged above the backfill layer of construction waste slag on the site; the cement stone powder filter layer (3) arranged above the graded crushed stone layer; The top layer (1) on top of the layer. The beneficial effects of the utility model are: it mainly conforms to the gardening concept of modern gardens embodying natural ecology, has water permeability and anti-sedimentation function, and is lower than the cost of pouring concrete bases, and avoids the unimpeded drainage of the bases when the drainage system is not good. There will be a natural water seepage function system in the rainy season or the rainy season, and it will not collect water.

Description

The base pavement structure of squares, parking lots and garden roads

technical field

The utility model relates to a base pavement structure for squares, parking lots and garden roads.

Background technique

During the construction of squares, parking lots, etc., there are usually a lot of on-site garbage that needs to be disposed of, and, under the concept of advocating natural ecology in modern gardens, how to effectively treat on-site garbage in squares, parking lots, and garden roads It is the technical problem to be solved in this case to make use of and effectively guarantee the natural water seepage in rainy season or rainy season.

Utility model content

The purpose of this utility model is exactly in order to solve above-mentioned problem, provides a kind of base pavement structure of square, parking lot and garden road.

In order to achieve the above object, the utility model adopts the following technical solutions:

The base pavement structure of squares, parking lots and garden roads, including:

A foundation bearing layer (6) composed of rammed earth;

The site construction waste slag backfill layer (5) set on the foundation bearing layer;

A graded crushed stone layer (4) arranged above the backfill layer of construction waste slag on the site;

A cement stone powder filter layer (3) arranged on the graded crushed stone layer;

The surface layer (1) is arranged on the cement stone powder filter layer through the bonding layer (2).

The thickness of the graded gravel layer is 200mm.

The thickness of the cement stone powder filter layer is 50mm.

The surface layer is stone, permeable brick or permeable concrete layer, grass-planting lattice, grass-planting brick.

The utility model has the following beneficial effects: it mainly conforms to the gardening concept of modern gardens embodying natural ecology, has water permeability and anti-sedimentation function, and is lower than the cost of pouring concrete bases, and avoids the unimpeded drainage of the bases when the drainage system is not good. There will be a natural water seepage function system in the rainy season or the rainy season, and it will not collect water.

The pavement structure effectively utilizes on-site waste.

detailed description

In order to make the technical means, creative features, goals and effects achieved by the utility model easy to understand, the utility model will be further elaborated below in conjunction with specific embodiments.

As shown in FIG. 1 , the base pavement structure of the square, the parking lot and the garden road includes: a foundation bearing layer 6 composed of rammed earthwork.

The site construction waste slag backfill layer 5 set on the foundation bearing layer, the foam and wood blocks in the site waste must be removed, and the site waste must be rolled and compacted after backfilling. The site waste used in this structure can reduce re-pollution of the environment by foreign transport , Save the cost of foreign transportation, shorten the construction time, promote the progress of the site, and at the same time meet the requirements of the civilized construction standards on site, and play a water filtration effect.

The graded crushed stone layer 4 arranged above the backfill layer of construction waste slag on the site mainly plays the role of water seepage and filtration, and the thickness of the graded crushed stone layer is 200 mm.

The cement stone powder filter layer 3 arranged on the graded crushed stone layer, the thickness of the cement stone powder filter layer is 50mm, which also plays a certain leveling effect.

The surface layer 1 arranged on the cement stone powder filter layer through the bonding layer 2, the surface layer is stone material, permeable brick or permeable concrete layer, grass-planting lattice, grass-planting brick.

The above descriptions are only preferred implementations of the present utility model, and the scope of protection of the present utility model is not limited to the above-mentioned implementations. All technical solutions belonging to the principle of the utility model belong to the protection scope of the utility model. For those skilled in the art, some improvements made on the premise of not departing from the principle of the utility model, these improvements should also be regarded as the protection scope of the utility model.
