Description
Technical field
The utility model relates to the device that a kind of groundwater recharge is used, and relates in particular to a kind of Recharge cage.
Background technology
Water source heat pump air conditioning system is a kind of air-conditioning system of coming to provide for building refrigeration, heating, domestic hot-water supply by the energy that draws in the water sources such as underground water, surface water, municipal sewage.In recent years, along with being rooted in the hearts of the people of ideas such as environmental protection, energy savings, particularly the Olympics Olympic Games in 2008 are held in the Pekinese, and the Green Olympics gets more and more people's extensive concerning.Under this kind historical background, water source heat pump air conditioning system also because its initial cost and operating cost are very cheap, has been subjected to increasing favor sight simultaneously as a kind of air-conditioning system of green.
By digging pumped well, inverted well, use the water source heat pump system of underground water form because it has more general adaptability than alternate manner, so in the engineering project that all present water source heat pump systems are used, occupy the overwhelming majority.
Yet, As time goes on, recharge well in some engineering projects, groundwater recharge speed occurred and obviously slowed down even recharge the problem of not going back.The generation of this problem makes the efficient of water source heat pump system operation greatly reduce, and simultaneously, owing to recharge slowing down of speed, has caused underground water to overflow and has recharged well, has wasted great amount of water resources.Cause the reason of this situation mainly to be:
1. because underground water has the certain pressure and the resistance of permeable stratum, therefore there are the slow characteristics of recharging easily that extract generally.
2. underground water contains the mineral microorganism, in the process that extraction is recharged, will produce the viscosity gelatinous precipitate through physical-chemical reaction.
3. recharge water infiltrates to the stratum from the time of filtration of well casing filter pipe.In the process of recharging, the viscosity gelatinous precipitate will bond and stop up the time of filtration of filter pipe, and this directly causes sharp the falling of permeability rate of well casing.
For preceding two reasons, present technological means also can't propose solution effectively.But, can be solved by certain technological means for the 3rd reason.
The structure of traditional inverted well and the consistent (see figure 1) of the structure of pumped well, they all design according to " Technical standard for water supply well " and construct.The a certain specific practice of well casing is: well casing adopts spiral welded pipe, and in corresponding water-bearing layer, stratum part, with every mitron section 45 row, the standard in every row 17 holes is opened the hole of diameter 18mm on pipeline section.8 of the reinforcing bars of the outer equidistant weld diameter 6mm of pipeline section equidistantly twine with galvanized iron wire then.The well casing of water-bearing layer part is called filter pipe.
Among Fig. 1:

The b-filter pipe
The c-spiral welded pipe
The artificial backfill gravel of d-material
Structure by analytical calculation tradition inverted well can draw:
1. the permeability rate of traditional inverted well is low.Permeability rate is institute's hole-opening area and the ratio of corresponding pipeline section area.By calculating the well permeability rate that recharges that can learn theoretical design only is 0.19.And in the work progress of reality, permeability rate only remains on about 0.15.
2. because inverted well is according to the structural design of pumped well, so the gap of the galvanized iron wire that is twined in the water-bearing layer part is consistent with pumped well.
Know that therefrom its permeability rate of traditional inverted well is original just little, adds the viscosity gelatinous precipitate that produces in the use and has stopped up permeable hole again, the result causes groundwater recharge speed obviously to slow down even recharges and do not go back.
The utility model content
The purpose of this utility model is to provide a kind of Recharge cage, can improve groundwater recharge speed.
For achieving the above object, the Recharge cage that the utility model provides is a column cage body, and the compartment of terrain is provided with metal section, and integrally welded with reinforcing bar between each metal section, reinforcing bar is wound with wire outward.
By said apparatus reduced effectively the viscosity gelatinous precipitate take place bonding situation.

The specific embodiment
Below in conjunction with Fig. 2,3, enumerate an embodiment the utility model is described in detail.
The pipeline section 10 that spiral welded pipe is cut into 60mm is welded into a column cage body with reinforcing bar 11 with each pipeline section 10 as column, is wound with wire 12 outside reinforcing bar 11.
Reinforcing bar 11 its quantity and the distance between each root reinforcing bar 11 that are welded on the pipeline section 10 are not strict with.
The wire 12 that twines on the reinforcing bar 11 can be galvanized iron wire or iron wire, and is vertical with reinforcing bar to winding, as shown in Figure 2.
The concrete using method that the utility model provides is:
A, press the well hydrogeologic data, place Recharge cage in corresponding water-bearing layer part, the upper and lower end of Recharge cage is integrally welded with spiral welded pipe respectively, will weld the backwater well casing of getting well again and insert inverted well, sees also Fig. 4.

In actual use, the Recharge cage that the utility model provides can be by adjusting the wire gap, so that the backwater smoothness, and the borehole wall can be fixed again and do not collapse.
The Recharge cage that the utility model provides has solved tradition and has recharged the situation that the viscosity gelatinous precipitate bonds together in the well, has improved permeability rate.
The Recharge cage experimental session that the utility model provides has been obtained good effect:
Project 1: Haidian District Beijing hummingbird community.About 80,000 square metres of this sub-district construction area is a high-end residential substantially, and a small amount of retail shop is arranged.Whole sub-district adopts all that water source heat pump system freezes, heating, domestic hot-water's supply.
Project 2: Chaoyang District Beijing Jiang Zhuan lake tennis club.This club is the high-grade club of 6000 square metres of construction areas.Whole employing water source heat pump systems freeze, the heating supply.
Although the hydrogeological situation of top two projects differs greatly, two projects are all stable.By being arranged on the monitoring arrangement in the inverted well, can see that the situation that does not all have sediment to bond together in the inverted well of two projects produces.
Advantage of the present utility model:
1. solve puzzlement HVAC circle groundwater recharge problem for many years, eliminated people to water The query of source heat pump system.
2. improved the applicability of water source heat pump system, the place size to well position number quantitative limitation fall Arrived minimum level.
3. reduced the total cost of water source heat pump system, the application of twin-well tubular construction can reduce recharges The quantity of well, thus make water source heat pump system have more economy.
