Abstract
A new river water-taking device comprises a well body and a filtering body. A frame structure made of beams and poles and a well wall made of big hole concrete are arranged around the well body. The filtering body is a sand stone pile body whose section is an inversed trapezoid. The lower layer is a water storage layer made of big stones and middle-sized stones. The central layer is a filtering layer made of small stones; and the upper layer is a filtering layer made of coarse sand and medium sand. Compared with ordinary water plants, the utility model can save investment, land, energy and electricity. No pollution is caused to the water and zero emission is realized. Meanwhile, the low operation cost cuts down water supply cost.
Description
Technical field
The utility model relates to a kind of novel river water fetching device that is used for civilian or indusqtrial water supply factory.
Background technology
Most of at present factories from the beginning are by the pump house that is located at the river bank, directly river are drawn up ground also through after a series of processing, deliver to users' again.Water factory must build a whole set of precipitation, filtration and drainage on ground for this reason, and building a water factory must have sizable investment.
Summary of the invention
The technical problems to be solved in the utility model provide after a kind of water intaking need not to water treatment or only simple process just can be directly for the novel river water fetching device of user's use.
The utility model solves the problems of the technologies described above with following technical scheme: water fetching device comprises well body and filtering bodies, around the well body by the frame construction of forming by beam, post and the borehole wall that constitutes by coarse porous concrete; Filtering bodies is that a cross section is down trapezoidal sandstone heap body, lower floor's water storage layer that stone is formed among the Da Shi of serving as reasons, and the middle level is the transition zone of being made up of gravelstone, the upper strata is the filtration beds of being made up of the coarse sand medium sand.
River of the present utility model water fetching device is compared with conventional water factory, can reduce investment outlay, and saves the area, and is energy-conservation, economize on electricity, and water pollution is little, zero-emission, operating cost is low, and water supply cost is low.
Description of drawings
Fig. 1 is the structural representation of river of the present utility model water fetching device.
The specific embodiment
Water fetching device of the present utility model comprises well body and filtering bodies, around the well body by the reinforced concrete frame structure of forming by bottom girder 1, back timber 3, post (not shown) and top cover 4 and the borehole wall 2 that constitutes by coarse porous concrete, in the well body in addition with the component and fitting ventilating pipe 6 of supporting intake pipe 7 of water pump and well body, manhole 5, cat ladder 8 etc.; Filtering bodies is that a cross section is down trapezoidal manufactured sand clitter body, lower floor's water storage layer 9 that Da Shi and middle stone are formed of serving as reasons, and the middle level is the transition zone of being made up of gravelstone 10, the upper strata is the filtration beds of being made up of coarse sand and medium sand 11.
This water fetching device is built on the river shoal or artificial river shoal 15 with certain depth of water, and filtering bodies can be built on excavation line 13 and riverbed 14; Whole water fetching device is positioned at the water surface below 16.Each layer stone sand from bottom to top, the descending horizontal lay of particle diameter.
During the work of this water fetching device, under the effect of water-head inside and outside the well, river successively penetrates into water storage layer 9 from filtration beds 11, transition zone 10, is pooled in the well from the borehole wall 2 and shaft bottom at last, is taken out by intake pipe 7 and delivers to the user.
The well location can be chosen in the river openr straight, have certain river shoal thickness and (generally be not less than 2m, do not reach requirement if do not possess and can form " artificial river shoal ") and be not easy to build on the section of alluvial and the certain depth of the water submerging of tool (generally being not less than 0.5m), the depth of water is more preferably greater than 2 meters.The well body generally is designed to circle, and better because of stress condition, it is also relatively easy to construct; Also can be designed to square other shape that waits.The hole diameter size is then decided according to the water supply needs, the too small output that influences, and excessive construction is difficulty; Generally getting 5~12M is advisable.If output is very big, individual well does not satisfy requirement, can build a plurality of wells yet and form " gang of wells " water supply.
Filtering bodies is formed the multiple filtration structure by Da Shi, middle stone, gravelstone, coarse sand, medium sand, adopts cross section inverted trapezoidal structure wide at the top and narrow at the bottom to help enlarging the infiltration area, increases filtering bodies water percolating capacity and water retention capacity, improves drainage quality and efficient.
Below be a permeable amount calculated example of filtering bodies:
If the well body is an external diameter 6.6m, the cylinder of high 3.0m is with a cross section outside and is down trapezoidal ring-type filtering bodies, trapezoidal high 3.0m, bottom side length 4.0m, last length of side 8.0m.
Then the permeable amount of filtering bodies can be calculated as follows:
q=k·w·h/l
Permeable amount (the m of q---wherein
3/ day)
The k---transmission coefficient is got gravelstone, coarse sand, medium sand average: 45m/ day
The w---area that seeps water, promptly trapezoidal top annulus area is 300m
2
The l---seepage paths is long, and gravelstone, coarse sand, medium sand three thickness sum are 1.0m
The h---water-head can be approximated to be the difference of water level and river surface water level in the well.
Suppose drawdown 1.0m in the well, corresponding permeable amount is respectively in the time of can calculating depth of the water submerging 0.5m, 1.0m, 2.0m and 3.m water level by following formula: 20250m
3/ day, 27000m
3/ day, 40500m
3/ day and 54000mm
3/ day.
This water fetching device can deposit in the surperficial generation of filtering bodies and influence output than after long running time, and the way of solution is when annual flood end or low water stage, adopts artificial or mechanical agitation water surface removing mud.
