Description
Technical field
The utility model relates to a kind of foundation structure that reduces the impervious barrier basal plane top layer water yield, is especially applied to the antiseepage foundation structures of field taking compacting clay as basic unit such as petrochemical industry, Coal Chemical Industry, municipal administration.
Background technology
The fields such as petrochemical industry, Coal Chemical Industry, municipal administration are equipped with the liquid storage pond of different technologies, scale requirement according to technological requirement, be wherein no lack of ultra-large airing pond, the accident pool etc. of square meters up to a million.These liquid storage ponds consider that according to national requirements for environmental protection and investment cost aspect many employing compacting clays are basic earth working material impervious barrier structure in recent years, but this foundation structure inevitably can be subject to the impact of gushing on ground precipitation and underground water in work progress, not only affect the construction speed of whole pond body, and ground is subject to earth's surface water to soak quality and the security of operation that even can affect whole pond body when serious.Therefore need a kind of foundation structure that reduces the impervious barrier basal plane top layer water yield.
Summary of the invention
The purpose of this utility model is to provide a kind of foundation structure that reduces the impervious barrier basal plane top layer water yield.
To achieve these goals, the technical solution adopted in the utility model is: in liquid storage pond (1) impervious barrier basal plane (2) following water table settings " fish-bone " type underground water guide systems (3); Carry out subregion on impervious barrier basal plane (2) top layer, each ten thousand square meter arranges a collecting-tank (4), and collecting-tank (4) specification is the high 0.5m of the wide 5m of long 5m, grade of side slope 1: 2; The pumping equipment (5) of placing dimension in collecting-tank (4) is discharged the ponding collecting.
The foundation structure in liquid storage pond (1) is compacting clay basic unit.
Underground water guide system (3) arranges guide supervisor in the middle of adopting, guide supervisor both sides are symmetrical arranged the fish bone well structure of guide arm, and wherein discharge guiding pipe is the perforate floral tube of HDPE material.
The collecting-tank (4) arranging according to every ten thousand square meters should be positioned at the minimum point place of this subregion, and the region of less than 10,000 square meters arranges according to a collecting-tank (4), and specification is the high 0.5m of the wide 2m of long 2m.
The beneficial effects of the utility model are: adopt the foundation structure of this reduction impervious barrier basal plane top layer water yield to derive effectively and rapidly top layer and collect water, reduce to greatest extent the impact of top layer water on impervious barrier construction, thereby the reduction of erection time, save construction cost, avoid occurring top layer, gene basis long-term water immersion effect workmanship and use safe hidden danger.
Brief description of the drawings
Below in conjunction with accompanying drawing and example, the utility model is further illustrated.
Fig. 1 is a kind of liquid storage pond schematic top plan view that reduces the impervious barrier basal plane top layer water yield of the utility model.
Fig. 2 is a kind of collecting-tank cross-sectional schematic that reduces the impervious barrier basal plane top layer water yield of the utility model.
1. liquid storage ponds in figure, 2. impervious barrier basal plane, 3. underground water guide system, 4. collecting-tank, 5. pumping equipment.
Detailed description of the invention
At liquid storage pond (1) impervious barrier basal plane (2) water table, underground water guide system (3) is set, prevents from gushing on underground water for collecting underground water simultaneously.Carrying out zoning design according to the scale in liquid storage pond (1), is a subregion according to each ten thousand square meter region, and less than 10,000 square meters are by a subregion.Be the collecting-tank (4) that the wide 5m degree of depth of long 5m is 0.5m in a specification of the minimum point place of each subregion excavation, collecting-tank (4) specification of less than 10,000 square meters is the high 0.5m of the wide 2m of long 2m.For ensureing that top layer ponding flows in pond fast, collecting-tank (4) side slope adopts 1: 2 gradient.Complete after underground water guide system (3) and collecting-tank (4), in liquid storage pond (1), arrange impervious barrier basal plane (2).In the collecting-tank (4) of laying impervious barrier, place pumping equipment (5), discharge in time the ponding collecting.
Claims (4)
1. a foundation structure that reduces the impervious barrier basal plane top layer water yield, is characterized in that: in liquid storage pond (1) impervious barrier basal plane (2) following water table settings " fish-bone " type underground water guide systems (3); Carry out subregion on impervious barrier basal plane (2) top layer, each ten thousand square meter arranges a collecting-tank (4), and collecting-tank (4) specification is the high 0.5m of the wide 5m of long 5m, grade of side slope 1: 2; The pumping equipment (5) of placing dimension in collecting-tank (4) is discharged the ponding collecting.
