Description
Background technology
This utility model relates to water supply project field of structural design, is more specifically a kind of water intaking structure for pumping plant river course.
Background technology
For pumping plant river course water intake engineering, engineering design the most successfully it is critical only that can design pumping plant water intaking structure adapt to the feature in water intaking river course, typically builds the water intaking structure in river course and all faces the alluvial of water intaking structure, the problem that phase range of stage big vast, withered is big.The method of current domestic employing is usually taked to dig in river bed and is built intake pool diversion, but owing to silt in some rivers, impurity are more, intake pool easily deposits, and direct water intaking can cause water pump efficiency of producing drinking water to decline；The silt, the impurity that are mingled with in water produce serious abrasion also can be greatly shortened the service life of pump equipment to impeller, the blades of water pump；Simultaneously because impurities in water content is higher, increase the workload that subsequent purification processes.It is thus desirable to often intake pool is carried out desilting, the manpower of input and time cost are relatively big, and later stage operating cost is higher.
General river pumping station water intake engineering, builds flume diversion to water intaking pond or the water-supply method of pump house in being typically employed in river course；This type of designs the river course more for bed load, flume and the alluvial of water intaking pond easily occurs flood season, causes and need in running to carry out continuous desilting, desilting workload is big, and impact water intaking water quality, bed load is also easily accessible water pump and causes water pump to damage simultaneously, and maintenance workload is big.
Additionally in the river course that some dry season water level is relatively low during water intaking, for ensureing the suction head of drinking-water pipe, the base plate of intake pool arranges relatively low, and quantities is bigger.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming that among above-mentioned background technology, intake pool easily deposits, and proposes a kind of water intaking structure for pumping plant river course, which reduces desilting workload, reduces operating cost.
A kind of water intaking structure for pumping plant river course of this utility model, the concrete water filter pipe connected including afterbody and intake pool, high water level water inlet pipe is set near side, river at described intake pool, it is provided with concora crush hole at the top of described intake pool, pumping for water pump pipe is set bottom the tail end of described intake pool, described intake pool tail end top is provided with exhaustor, it is characterized in that: described concrete water filter pipe has some, some described concrete water filter pipes are embedded in bottom riverbed side by side, described concrete water filter pipe is enclosed with double-deck geotextiles in advance, the most alternate outside concrete water filter pipe described in double-deck geotextiles it is enclosed with rubble drainage body and double-deck geotextiles being enclosed with in advance, spaced apart treatment hole is had on described concrete water filter pipe.
In technique scheme: be equipped with rubble drainage body, double-deck geotextiles, rubble drainage body, double-deck geotextiles and steel wire in described concora crush hole the most successively.
In technique scheme: be provided with ball valve on described high water level water inlet pipe.
In technique scheme: the position of described pumping for water pump pipe is determined by lowest water level in dry season and water pump suction head.
This utility model has the advantage that filter pipe passes through outsourcing rubble and geotextiles, serve the effect of filtration and infiltration water, it is to avoid the alluvial of intake pool.Meanwhile, this technology is adapted to various different head, decreases water intaking pond excavated volume, efficiently solves the problem that river bed alluvial causes efficiency of producing drinking water to decline, decrease desilting workload simultaneously, reduce operating cost.

Detailed description of the invention
Performance of the present utility model is described below in conjunction with the accompanying drawings, but they are not intended that restriction of the present utility model, the most for example.Simultaneously by illustrating that advantage of the present utility model will become clearer from easy to understand.
With reference to shown in Fig. 1: a kind of water intaking structure for pumping plant river course, it include some be embedded in side by side bottom riverbed in column type concrete water filter pipe 1, the parameters such as concrete water filter pipe 1 caliber, pipe range, aperture, quantity calculate according to design water draw rate, to ensure the water intaking ability in the case of low water level.Concrete water filter pipe 1 uses double-deck geotextiles 2 to wrap up, and top and bottom are respectively provided with certain thickness rubble drainage body 3, also lays double-deck geotextiles 2 and filter in rubble drainage body 3.
Described concrete water filter pipe 1 is enclosed with double-deck geotextiles 2 in advance, being enclosed with in advance, hoop on the concrete water filter pipe 1 described in double-deck geotextiles 2 is alternate is enclosed with rubble drainage body 3 and double-deck geotextiles 2, on described concrete water filter pipe 1 interval be disposed with treatment hole 4 (with reference to Fig. 2,3).
The afterbody of described concrete water filter pipe 1 connects with intake pool 5, and water intaking ability when shown intake pool 5 uses enclosed construction to be to improve high water level, intake pool 5 sets high water level water inlet pipe 6 by side, river；Intake pool 5 top sets concora crush hole 7, sets rubble drainage body 3 and double-deck geotextiles 2 in concora crush hole 7；Setting pumping for water pump pipe 8 bottom intake pool 5 tail end, pumping for water pump pipe 8 position is felt according to withered phase lowest water level and water pump suction head；Intake pool 5 tail end top arranges exhaustor 9, discharges additional air in intake pool.
Rubble drainage body 3, double-deck geotextiles 2, rubble drainage body 3, double-deck geotextiles 2 and steel wire 10 it is equipped with the most successively in described concora crush hole 7；Described high water level water inlet pipe 6 is provided with ball valve 6.1；The position of described pumping for water pump pipe 8 is determined by lowest water level in dry season and water pump suction head.
Concrete installation steps of the present utility model are as follows: (1) lays rubble drainage body 3 and double-deck geotextiles 2 bottom concrete water filter pipe 1 in advance；
(2) with reference to design size casting concrete filter pipe 1, intake pool 5, high water level water inlet pipe 6, pumping for water pump pipe 8, exhaustor 9 (with reference to Fig. 4) are installed；
(3) lay concrete water filter pipe 1 top rubble drainage body 3, double-deck geotextiles 2, lay the rubble drainage body 3 in concora crush hole 7, double-deck geotextiles 2 (with reference to Fig. 5).
The luffing of this intake pool phase water level big vast in being suitable for river course, withered, is effectively improved pumping plant water intaking fraction, greatly reduces desilting number of times and the desilting workload of water intake facilities, reduce later stage operation expense.Filtered by multilamellar geotextiles and rubble drainage body etc., improve water intaking water quality, extend the water pump operation cycle, alleviate the subsequent purification work of water intaking.
Above-mentioned unspecified part is prior art.
