Description
(1) technical field
This utility model relates to man-made lake technical field of construction, particularly to a kind of man-made lake backing layer.
(2) background technology
Man-made lake usually people are planned, have a kind of lake that purpose excavates, and produce under non-natural environment, bag
Include landscape lake and large-scale reservoir.Different with natural lake, man-made lake embodies the wisdom of human use and nature remodeling.
In man-made lake work progress, for preventing the steady decay of ecosystem, protection and saving water resource, particularly exist
The area that the north water resource critical shortage, subsoil water constantly decline, man-made lake must take comprehensive water saving and make-up water measure, with
Prevent the excessive seepage of lake water, here it is annoying many environment specialists and the lakebed Anti-seeping technology engineering of building expert.
At present, great majority be use the method laying antiseepage film to do lakebed seepage control project, with hindering in natural stratum
The infitration process of lower water, but the impervious barrier simple in construction of existing man-made lake, the repulsive force between soil particle is big, hygroscopic, lake
Interior water easy to leak and loss, it is impossible to reaching intended antiseepage purpose, ecological, environmental protective effect is poor.
(3) summary of the invention
This utility model is in order to make up the deficiencies in the prior art, it is provided that the water in a kind of rational in infrastructure, design science, lake
Easy to leak and loss, the man-made lake backing layer of anti-seepage effect excellence, do not solve problems of the prior art.
This utility model is achieved by the following technical solution:
A kind of man-made lake backing layer, including concrete cushion, lays the first sand bed course above concrete cushion,
Laying water-proof coiled material layer above first sand bed course, lays the second sand bed course, at the second sand pad above waterproof roll layer
Lay alert layer above Ceng, above alert layer, lay sandy gravel stratum, above sandy gravel stratum, lay geotextiles, spread above geotextiles
If plantation soil layer.
Described concrete cushion is 75mm thickness C20 plain concrete cushion layer；Described first sand bed course is 270-330mm thickness
One sand bed course；Described waterproof roll layer is HDPE waterproof roll layer；Described second sand bed course is thick second sand of 170-230mm
Soil padding；Described alert layer is the polyethylene netted spacer bed of material；Described sandy gravel stratum is 270-330mm thickness sandy gravel stratum；Described soil
The specification of work cloth is 400g/m2；Described plantation soil layer is that 470-530mm thickness plants soil layer.
The relative compaction of described first sand bed course, the second sand bed course and sandy gravel stratum is 90%；Described polythene net
The shape spacer bed of material is orange polyethylene netted spacer material.
The beneficial effects of the utility model are: this man-made lake backing layer is designed by said structure, can keep the water in lake
Not by seepage and loss, anti-seepage effect is excellent；This man-made lake backing layer is applied in the Anti-seeping technology structure of man-made lake, it is ensured that
The balance of ecosystem around lake water after man-made lake construction and lake, it is thus achieved that the most ecological more environmentally friendly places of cultural interest.
(4) accompanying drawing explanation
Below in conjunction with the accompanying drawings this utility model is further described.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of alert layer in Fig. 1.
In figure, 1 concrete cushion, 2 first sand bed courses, 3 waterproof roll layers, 4 second sand bed courses, 5 alert layers, 6 sand
