Abstract
The utility model belongs to the technical field of landscape engineering, in particular to waterproof layer structure of an artificial lake bottom. The waterproof layer structure comprises a cushion, a waterproof layer and a protective layer which are sequentially laid from top to bottom. Composite geomembrane is used as the waterproof layer, and pure soil or shoal soil can be obtained from local sources to be used as the cushion, so that multiple layers of structures are integrated to realize the waterproof effect of the artificial lake bottom, the overall water-proof effect is good, the cost is relatively lower, and the waterproof layer structure is suitable for various soil environments, thereby enhancing the construction quality of artificial lakes.
Description
Technical field
The utility model belongs to the landscape engineering technical field, is specifically related to a kind of artificial lake lakebed waterproof layer structure.
Background technology
In the urban landscaping engineering, do wetly for forming in conjunction with, ecoscape that sound is suitable, usually excavation is built artificial lake, runs off fast for preventing artificial lake lake water, must carry out waterproof construction.In the prior art, the artificial lake lakebed often adopts cement mortar to make waterproofing course on the bottom cushion basis, is easy to generate the crack after being impacted, and destroys waterproof effect; Simultaneously, the waterproof layer material of can not suiting measures to local conditions to choose causes the construction cost height.
Summary of the invention
The purpose of this utility model is to provide a kind of artificial lake lakebed waterproof layer structure, adopts geomembrane as main waterproofing course, is aided with sandwich construction as protection, gathers materials on the spot and chooses the job site material, makes artificial lake reach the excellent waterproof effect.
The technical solution of the utility model is as follows: a kind of artificial lake lakebed waterproof layer structure, constitute by bed course, waterproofing course, topping, and described bed course, waterproofing course, topping are laid from bottom to top successively.
Described bed course is re-layed layer of fine sand and is constituted by rammed earth on it, plain soil pressure real coefficient＞93%, and about 10cm is thick for fine sand layer.Under the beach condition, can gather materials on the spot and select for use beach soil to make bed course.
Described waterproofing course is the thick composite geo-membrane of 4mm, lays in the artificial lake lakebed is whole.Composite geo-membrane is as waterproofing course, and good water-proof effect is applicable to strong acid and strong base soil.
Described topping is by the thick fine sand of the about 10cm of one deck, and the top re-lays the thick one deck pea gravel concreten of about 10cm and constitutes.Adopt pea gravel concreten to replace the conventional cement mortar of selecting for use as topping, intensity is bigger, can more effectively protect the fine sand of lower floor.
The beneficial effects of the utility model are: gather materials on the spot and select plain soil or beach soil as bed course, economically feasible is saved cost, and is not reduced workmanship; Under the beach condition, effectively soft more as the topping of geomembrane with beach soil.Select for use composite geo-membrane as waterproofing course, the integrated multilayer structure is carried out artificial lake lakebed waterproof, and integral waterproofing is effective, and cost is relatively low, is suitable for various soil environments, has promoted the artificial lake construction quality.
Description of drawings
Fig. 1 is the lakebed waterproof layer structure schematic diagram of excavation artificial lake under the ordinary soil.
Fig. 2 is the lakebed waterproof layer structure schematic diagram of beach artificial lake.
The specific embodiment
The utility model mainly contains two kinds of specific embodiment, below in conjunction with accompanying drawing to being described further:
Embodiment one when implementing the utility model under ordinary soil, at first will excavate good artificial lake lakebed rammed earth, formin soil padding (1), coefficient of consolidation＞93% as shown in Figure 1; Lay the thick fine sand bed course of about 10cm (2) then thereon; The whole thick composite geo-membrane of 4mm (3) of laying of lakebed; Re-lay the thick fine sand for protection layer of about 10cm (4); Make the thick pea gravel concreten topping (5) of about 10cm at last.
Embodiment two when beach is implemented the utility model, at first with artificial lake lakebed beach rammed earth, forms beach soil padding (6), coefficient of consolidation＞90% as shown in Figure 2; The whole thereon then thick composite geo-membrane of 4mm (3) of laying; Gather materials on the spot again and lay about 10cm thick beach silt topping (7) with beach soil; Make the thick pea gravel concreten topping (5) of about 10cm at last.
Claims (4)
1. an artificial lake lakebed waterproof layer structure is made of bed course, waterproofing course, topping, it is characterized in that: described bed course, waterproofing course, topping are laid from bottom to top successively.
2. artificial lake lakebed waterproof layer structure according to claim 1 is characterized in that: described bed course is re-layed layer of fine sand and is constituted by rammed earth on it, plain soil pressure real coefficient＞93%, and about 10cm is thick for fine sand layer.
3. artificial lake lakebed waterproof layer structure according to claim 1 is characterized in that: described waterproofing course is the thick composite geo-membrane of 4mm, lays in the artificial lake lakebed is whole.
4. artificial lake lakebed waterproof layer structure according to claim 1 is characterized in that: described topping is by the thick fine sand of the about 10cm of one deck, and the top re-lays the thick one deck pea gravel concreten of about 10cm and constitutes.
