Description
Technical field
The present invention relates to permeate intake equipment, this infiltration intake equipment is in the situation that fetch water by river, lake, sea etc., and directly water intaking is buried the layer of sand of collector pipe by the bottom surface etc. underground infiltration water is fetched water and utilize.
Background technology
For by being embedded in that the inferior coiling shape filter tube in river region or riverbed or porose pipe duct are fetched water etc. to river bed water or free ground water or for the layer of sand of the bottom surface by river, lake, sea etc. etc. and utilize and bury collector pipe underground infiltration water is fetched water, using various infiltration intake equipments.Its representational equipment has following structure, that is: patent documentation 1 as shown in Figure 13 catchment bury canal around pile up the gravel of regulation particle diameter, and its particle diameter is diminished toward the outer side interimly, thereby form and to bury sandy gravel stratum underground, and return thereon and bury the native sand excavated to form native layer of sand.During water intaking, this soil layer of sand plays a role as the filter course that the impurity in water etc. is filtered.Running water facilities design guide according to Japan Water Works Association's distribution, bury underground sandy gravel stratum from lower beginning successively by large gravel, these three layers of gravels, little gravel consist of, it is suitable that the particle diameter of the gravel of large sandy gravel stratum is that the particle diameter of the gravel of 40～50mm, middle sandy gravel stratum is that the particle diameter of the gravel of 30～40mm, little sandy gravel stratum is that 20～30mm is considered to.
In the infiltration intake equipment, with regard to the pipe laying that catchments, the pipe laying of wishing to catchment has large aperture opening ratio and low inflow velocity when water intaking.That is, if the aperture opening ratio of the pipe laying that catchments is large, in order to obtain the water withdrawal of regulation, can make water slack-off to the inflow velocity of the pipe laying that catchments, correspondingly can reduce the obstruction of the pipe laying that catchments.
On the other hand, as continuing long-term water intaking, mud, fine sand and the rubbish that flows in the river-etc. will stop up the filter course of infiltration intake equipment, make thus the stream of water inaccessible, be said clogging thereby produce the water withdrawal minimizing.In addition, except these mud and sand, the part of the native sand of filter course is also invaded and is buried underground in sandy gravel stratum, thereby also causes the obstruction of burying sandy gravel stratum underground.
In order to eliminate such filter course and the obstruction of burying sandy gravel stratum underground, to the adverse current rinse water of pipe laying supply from adverse current rinse water supply source of catchmenting, the pipe laying that will catchment is as adverse current rinse water supply pipe, thus, can by from this adverse current rinse water supply pipe as upward water flow and injected rinse water clean and bury sandy gravel stratum and filter course underground.
pipe laying is as adverse current rinse water supply pipe in the situation that will catchment like this, following situation as can be known: to stop up and supply with equably rinse water from pipe to filter course be indispensable important document in order to eliminate, but, if the aperture opening ratio of pipe is large, exist a large amount of rinse water to concentrate on the tendency that flows in the larger several positions, gap between gravel in the large sandy gravel stratum of the lower floor that buries sandy gravel stratum underground, thereby produce bias current in the adverse current rinse water, the adverse current rinse water is supplied with to filter course equably, can only partly eliminate filter course and the obstruction of burying sandy gravel stratum underground.
therefore, in existing infiltration intake equipment, the pipe laying that will not catchment is used as adverse current rinse water supply pipe when back washing, but by counter-flow water to filter course and when burying sandy gravel stratum underground and cleaning, use the pipe arrangement of another contrary cleaning use and utilize the adverse current rinse water to clean, perhaps like that set supply from the compressed-air actuated air bleed pipe of compressed air feed mechanism in the sandy gravel stratum of the upside that buries canal that catchments as 1 record of above-mentioned patent documentation, and utilize the bubble that is produced by the compressed air from this air bleed pipe ejection to eliminate the obstruction of burying sandy gravel stratum and filter course underground.Like this, in existing infiltration intake equipment, when realizing by the pipe laying that catchments of having used the coiling shape filter with high aperture in the situation that the best is catchmented, for the obstruction of cleaning to eliminate filter course He bury sandy gravel stratum underground, need another contrary equipment that cleans the pipe arrangement of use and be used for supplying with pressure air or press water, this becomes the high reason of infiltration intake equipment cost.
