Abstract
The invention discloses a foundation structure for reducing surface water of an impermeable layer base plane. The foundation structure is mainly characterized in that a 'fishbone'-shaped underground water drainage system (3) is arranged on an underground water layer below the impermeable layer base plane (2) of a liquid storage pond (1); the surface layer of the impermeable layer base plane (2) is partitioned, a water collecting pond (4) is arranged in each 10,000 square meters and is 5m long, 5m wide and 0.5m high, and the gradient of a side slope is 1:2; pumping equipment (5) with the corresponding specification is placed into each water collecting pond (4) to discharge collected water; the base structure of the liquid storage pond (1) is a compacted clay base layer; the underground water drainage system (3) adopts the fishbone structure that a main drainage pipe is arranged in the middle and drainage branch pipes are symmetrically arranged at two sides of the main drainage pipe; the drainage pipes are porous floral tubes made of a high-density polyethylene (HDPE) material; the water collecting pond (4) in each 10,000 square meters should be at the lowest point of the subzone; the zone smaller than 10,000 square meters is also provided with one water collecting pond (4) which is 2m long, 2m wide and 0.5m high.
Description
Technical field
The present invention relates to a kind of foundation structure that reduces the impervious barrier basal plane top layer water yield, the antiseepage foundation structure that compacting clay is basic unit is take in the fields such as petrochemical industry, Coal Chemical Industry, municipal administration that are especially applied to.
Background technology
The fields such as petrochemical industry, Coal Chemical Industry, municipal administration are equipped with according to technological requirement the liquid storage pond that different technologies, scale require, and are wherein no lack of the ultra-large airing pond, accident pool of square meters up to a million etc.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 object of the present invention 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 used in the present invention is: in liquid storage pond (1) impervious barrier basal plane (2) following water table settings " fish-bone " type underground water guide systems (3); On impervious barrier basal plane (2) top layer, carry out subregion, 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; In collecting-tank (4), place the pumping equipment (5) of dimension and discharge 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 invention has the beneficial effects as follows: 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.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and example, the present invention is further described.
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 present invention.
Fig. 2 is a kind of collecting-tank cross-sectional schematic that reduces the impervious barrier basal plane top layer water yield of the present invention.
1. liquid storage pond, 2. impervious barrier basal plane, 3. underground water guide system, 4. collecting-tank, 5. pumping equipments in figure.
The specific embodiment
At liquid storage pond (1) impervious barrier basal plane (2) water table, underground water guide system (3) is set, for collecting underground water, prevents from gushing on underground water simultaneously.According to the scale in liquid storage pond (1), carrying out zoning design, is a subregion according to each ten thousand square meter region, and less than 10,000 square meters are by a subregion.The collecting-tank (4) that is 0.5m for the wide 5m degree of depth of long 5m in 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 guaranteeing 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); On impervious barrier basal plane (2) top layer, carry out subregion, 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; In collecting-tank (4), place the pumping equipment (5) of dimension and discharge the ponding collecting.
