Abstract
The utility model disclosing a thin greenbelt water drainage layer on a basement roof and aiming at providing a thin greenbelt water drainage layer on a basement roof which has the advantages of free water drainage, high water releasing ability and avoiding the clogging of pipe networks and lowering down the engineering cost comprises a basement roof, a sandwich plate, a geo-textile, a sand layer and soils, wherein, the basement roof is provided with a sandwich plate and covered with a geo-textile and a sand layer which is covered with soils is arranged on the geo-textile; the sandwich plate is fixed on the basement roof through shoot nails and rubber gaskets and the sandwich plate surface is downward; the raised point of the sandwich plate is put upward and the sandwich plate is formed into a stereo sandwich plate with regular round raised points through molding by adopting flat plastic plates. The utility model is suitable for large greenbelts in building basement roofs.
Description
Technical field
The utility model relates to a kind of drainage blanket, and more particularly, it relates to the slim drainage blanket in large-scale greenery patches on a kind of basement roof.
Background technology
China adopts newly-built large-scale greenery patches to come the beautifying city and improve urban ecological environment in many big or middle cities at present, in order to make full use of land resources, will build large-scale basement usually and come as communal facilitys such as garage parking, markets under large-scale greenery patches.Former large-scale greenery patches soil layer adopts the drainage blanket of being made of the thick 50cm of reaching sand, cobble, microlith down, consideration for factors such as costs of investment, basement is buried to be restricted, thickness of earth covering on the basement roof is restricted too, in order to satisfy the needs of plant root growth, soil layer must guarantee the greening the thickness of the layer, so just can not be used the drainage blanket of the thick 50cm of reaching that is made up of sand, cobble, microlith down again.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides that a kind of to have a draining unobstructed, and discharging capacity is strong, and thickness only is the slim drainage blanket about 10cm, has reduced on the basement roof the slim drainage blanket in greenery patches on the basement roof of thickness of earth covering.
The utility model comprises basement roof, sandwich slab is set on basement roof, sandwich slab adopts Plastic Flat sheet material through the three-dimensional sandwich slab of mold pressing formation with regular circular protrusions point, sandwich slab is fixed on the basement roof with nailing and rubber sheet gasket, its plane of sandwich slab is downward, and raised points is upwards placed, and covers geotextiles on it, on geotextiles, lay layer of sand, on layer of sand, cover earth.Effect of the present utility model is:
It is unobstructed to the utlity model has draining, the characteristics that discharging capacity is strong, it has stopped the soil particle loss, avoided the pipe network obstruction, owing to make the basement roof under the greenery patches eliminate water pressure, have the antiseepage function, reduced the thickness of earth covering under the greenery patches simultaneously, reduced construction costs, the utility model is applicable to the large-scale greenery patches on the building basement.
Description of drawings
Fig. 1 is the utility model structural representation
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
It comprises basement roof 1 the utility model, sandwich slab 2 is set on basement roof 1, cover geotextiles 3 on it, on geotextiles 3, lay layer of sand 4, on layer of sand 4, cover earth 5, wherein sandwich slab 2 usefulness nailings and rubber sheet gasket are fixed on the basement roof 1, sandwich slab 2 its planes are downward, raised points is upwards placed, sandwich slab 2 adopts Plastic Flat sheet material through the three-dimensional sandwich slab of mold pressing formation with regular circular protrusions point, because raised points supporting, form the horizontal drainage passage between the flat board of geotextiles 3 and sandwich slab 2, layer of sand 4 has formed the vertical drainage passage with geotextiles 3, and the earlier vertical laggard entry flat raft of the seepage flow aquaporin of the water in the soil layer of greenery patches enters the facility that catchments through the horizontal drainage passage again.
Embodiment of the present utility model;
From covering water or the surface water that earth 5 infiltrates, under action of gravity, enter layer of sand 4 and geotextiles 3 carries out losing water pressure behind the drainage, enter the space that all protruding round dot of sandwich slab 2 is constructed, the Channel Group's passage that forms along cavity is flowed to low by height, focuses in the city planting ductwork and discharges.
