Description
Technical field
The present invention relates to a kind of recharge well that the self-leak type free groundwater recharges that is used for, particularly a kind of circle belongs to the water conservation technical field from oozing the recharge well wellhead assembly.
Background technology
How how water conservation prevents in the coastal area that perhaps the inwelling because of exhaustive exploitation underground water causes from being the key subjects of restriction local people life and economic development in the area of some lack of water; And the means that solve this problem are except strengthening people's consciousness of saving water, and effectively utilizing rain flood resource also is one of important measures.
In order to make full use of rain flood resource, in the ephemeral stream that does not have pollution or light contamination, usually arrange a kind of recharge well that self has particulate contamination function in the filtered water, promptly from oozing recharge well, also claim anti-filter recharge well, machine seepage well.That adopts at present oozes anti-recharge well certainly by recharging the pond and common recharge well is formed; Wherein recharge the pond and be embedded in undergroundly usually, be shape of falling the Sifangtai or circle, about dark 1m; Backfill sand, rubble two-stage filter material in the pond are used to filter river and river are recharged to recharge well; Recharge well is positioned at and recharges in the middle of the pond bottom, is columned cavity, its well head add a cover one have an eyelet concrete well cover; When the river process is recharged the top, pond; Gather via sand, the infiltration of rubble two-stage filter material, get in the recharge well, realize that water conservation recharges through eyelet on the concrete well cover.But this problem of oozing the recharge well existence certainly is: 1, ooze recharge well certainly and place at the bottom of river bed or the canal, very easily become silted up and block up and washed out by current, influence application life; 2, recharge the pond and be embedded in undergroundly, only recharge one of the pond end face section of freely intaking, for guaranteeing enough amounts of recharging, recharging the pond needs bigger cross sectional area, and great in constructing amount; 3, build the common pond of recharging and need backfill 10m
3About sand, rubble, consume a large amount of constructional materialss; 4, the use of concrete well cover has influenced the amount of recharging.These defectives have had a strong impact on the result of use of recharge well, do not bring into play its water conservation usefulness to greatest extent.
Summary of the invention
Existing in order to overcome from the defective of oozing recharge well; The purpose of this invention is to provide a kind of circle from oozing the recharge well wellhead assembly; This device self water recharge capacity is strong, has the function that prevents that low water stage sewage from recharging, and also has anti-filter function and certain anti-silt impact resistance; Be easy to construction simultaneously, saved the sandstone filter material.
The technical solution adopted for the present invention to solve the technical problems is: this kind circle is from oozing the recharge well wellhead assembly; Relate to recharge well and well head thereof; Described recharge well is positioned at below ground at the bottom of river bed or the canal, it is characterized in that, is being provided with the wellhead assembly that covers in above the well head on the recharge well; Described wellhead assembly comprises the well lid at a circular no end, and is fixedly set in the geotextile loaded filter in the well lid outside; The hollow that described well lid is made up of circular top cover and the sidewall that is vertically connected at around the top cover does not have the foundation body; Described lower sidewall is positioned at below ground at the bottom of river bed or the canal, and the middle and upper part is positioned at the bottom of river bed or the canal more than the ground; On top cover, be provided with the square aperture of top cover, on sidewall, be provided with the square aperture of sidewall, the square aperture of sidewall be positioned at the middle and upper part of sidewall and at the bottom of river bed or canal ground certain height is arranged; The geotextile loaded filter is arranged on top cover and the sidewall and covers has the part in square aperture; Recharge well is positioned in the middle of the wellhead assembly bottom, backfill sandstone filter material around the recharge well.
The square aperture of described sidewall is the rectangle aperture of above-below direction.
Described well lid is built by one of any material in steel bar concrete or concrete or masonry material or the hard chemical materials.
Described geotextile loaded filter is made up of the geotextile with anti-filter function; Described geotextile is for spinning geotextile or nonweaven geotextile; The geotextile loaded filter is tiled in above the top cover of well lid and outside, and is fixed on the well lid.
It is 1% inclined plane that described top cover is made horizontal plane or the tendency water (flow) direction gradient.
The invention has the beneficial effects as follows: this wellhead assembly self has the function and certain anti-silt impact resistance of granule foreign in the filtered water; And has a stronger water recharge capacity; And prevent the function that low water stage sewage recharges; Simultaneously reduced the import cross sectional area again, practiced thrift the sandstone constructional materials, also eliminated the influence of well lid the amount of recharging.Mainly show:
1. will recharge the pond and change wellhead assembly into, and carried to more than the ground by below ground, its sidewall also can be intake simultaneously, enlarges freely intake section number and cross-sectional area, reduces and recharges the pond volume.
2. increase wellhead assembly safeguard structure---top cover and the sidewall with certain intensity and shock-absorbing capacity, top cover and side-wall material are built by rigid plastics, steel bar concrete, concrete, masonry material; The wellhead assembly horizontal profile is done circular, and the wellhead assembly vertical direction is a linear pattern, has solved current to original impact of recharging the pond, and can prevent current scour.Wellhead assembly adopts circle to be easy to produce good manufacturability.
3. will recharge the pond and change wellhead assembly into, and carry to more than the ground by below ground; It is 1% inclined plane that the wellhead assembly top cover is made horizontal plane or the tendency water (flow) direction gradient; Cover the geotextile that one deck is easy to change at wellhead assembly top cover and sidewall, these measures can prolong from the application life of oozing recharge well greatly.
4. exposure is designed to waterproof body in the latter half of the wellhead assembly sidewall on ground, recharges to prevent face of land sewage.
5. remove original well lid, can be recharge water through unimpeded passage is provided.
