Abstract

The utility model belongs to a drainage well, which is composed of a reservoir, a water inflow channel, a filter screen, a well hoop and a sand bearing screen, wherein the water inflow channel is communicated with the reservoir, the well hoop is driven in deep underground section by section, a sand bearing screen is installed in the uppermost section, sand is filled on the sand bearing screen, well hoop walls of the lowest two sections are uniformly distributed with through holes, the well hoop is filled with stones and installed in the center of the reservoir bottom, and the filter screen is disposed in the reservoir. When it rains, water on the ground converges to the reservoir connecting with the drainage well by a channel, and permeates through the ground after being filtered to compensate groundwater which is pumped dry, thereby being more favorable for recycling rain, enabling rain-water to be more fully recycled, and relieving increasing water deficiency difficulty. Additionally, when heavy rain and rainstorm grow into flooding inundation, the drainage well can play a role of diverting and decrease loss caused by flooding.

Description

Drainage sump

Technical field

The utility model belongs to a kind of drainage sump.

Background technology

Rainwater part after raining evaporates, and a part flows into the sea, some additional underground water that permeates the ground.Be life and the industrial water that satisfies people, need in large quantities groundwater abstraction and cause the in short supply of water resource.Heavy rain and heavy rain can not in time be drained ground water and can be caused flood, and flood takes place climate warming again and again, seizes many people's life, bring tremendous loss for people's lives and properties.

Summary of the invention

The purpose of this utility model is in order to solve the deficiency that prior art exists, to permeate the ground more in order to make rainwater, replenishes groundwater resources and a kind of drainage sump is provided.

The technical scheme taked of the utility model is that this drainage sump is by reservoir, inlet channel, screen pack, well hoop and hold husky net and constitute for achieving the above object, inlet channel is communicated with reservoir, described well hoop one depths of being driven underground successively, go up most to be equipped with in the joint and hold husky net, hold sand and fill sand on the net, be evenly distributed with through hole on the well hoop wall of the most following two joints, fill up stone in the well hoop, the well hoop is located at the center of reservoir bottom, is provided with screen pack in the reservoir.

Described screen pack is divided into three layers, is skewed installation, and skin is big lattice screen pack, and the middle level is little lattice screen pack, and internal layer is the cloth screen pack, and the height of screen pack is higher than the height of reservoir.

The aperture of described through hole is less than the stone that is filled in the well hoop.

Also be provided with seepage mouth in the described reservoir, the screen pack bottom is provided with cleaning door.

Drainage sump of the present utility model be when raining with the water on ground by the irrigation canals and ditches productive set in the reservoir that connects drainage sump, flow into down after filtering with being penetrated into, the underground water that additional quilt is drained, more help the recovery and the utilization of rainwater, making it water can be recycling more fully, alleviates the difficult problem of lack of water day by day.In addition, when heavy rain and heavy rain caused flooding, this drainage sump can play the effect of shunting, reduced the loss that flood causes.

The specific embodiment

As shown in Figure 1 and Figure 2, drainage sump of the present utility model is by reservoir, inlet channel, screen pack, well hoop and hold husky net and constitute, described well hoop 1 can become cylindric with materials processings such as concrete, steel pipe or plastic pipes, and the big I of its caliber is pressed the actual needs face and determined.With successively a well hoop 1 depths of being driven underground, nethermost two joints will be arranged on the place, sandstone aquifer of good water permeability, and well hoop 1 is driven underground behind the depths, fill stone 9 to going up most a bottom of saving well hoop 1 well hoop 1 in.Go up most to be equipped with in the joint well hoop 1 and hold husky net 7, online filling sand 14 is to well hoop 1 top, and sand is to be used for the water that has impurity is filtered.Be distributed with through hole 8 equably on the described nethermost two joint well hoop walls, the aperture of this through hole 8 gets final product less than the stone 9 of filling.One reservoir 3 is set going up most a joint well hoop 1 periphery, well hoop 1 is located at the center of reservoir 3 bottoms, and the position of reservoir 3 should be built below the face of land, the about 2-3 rice of its degree of depth, and the about 50-60 cubic meter of moisture storage capacity can strengthen or dwindle as required.In described reservoir 3, the three layer filtration net is set, skin is big lattice screen pack a 4 (mesh size about 30 * 30mm), mainly be to filter leaf, branch, the rubbish that wooden unit etc. are big, the middle level is little lattice screen pack a 5 (mesh size about 10 * 10mm), carry out secondary filter, nexine is a cloth screen pack 6, further filter tiny impurity etc., the height of screen pack will be determined according to the actual conditions of locality, the height of the water surface in the time of should surpassing big flood, prevent that filtered from having the sewage obstruction well head of impurity, water just can not be freely along under the inflow place, ground, when screen pack is installed certain gradient to be arranged, prevent that mesh is blocked, have cleaning door 13 in the bottom of screen pack, personnel's turnover when conveniently reservoir 3 being cleared up, top at reservoir 3 is communicated with inlet channel 2, the rainwater that gathers flows into reservoir 3 by inlet channel 2, through

filter screen

4,5,6 filter (setting of screen pack can increase or reduce as required), flow into drainage sump and filtration once more by sand enters into the most following two joint well hoops 1, through hole 8 from the well hoop wall permeates the ground in the water layer, thereby it is underground that rainwater can be refluxed as much as possible, and replenishes groundwater resources.After heavy rain or flood, after the ponding in the reservoir 3 was done from seepage mouth 12 seepage flow, cat ladder 10 entered in the pond and cleans.

The position of the utility model drainage sump will be determined according to geologic information and drilling data.
