Description
Technical field
The present invention relates to a kind of underground water recharging, regulating and controlling device.
Background technology
One, groundwater recharge Construction Control present situation
At present domestic aspect groundwater recharge, though some scholars are arranged in research, it is ripe that is that all right, and also there are different understanding in phreatic extraction and supply mechanism, and country does not also form any codes and standards in this respect.Though some area (as Shanghai, Shaanxi and other places) has also carried out some groundwater recharge examples, and the relevant technologies rules have been formed, but mainly carry out, having little significance of a certain concrete deep foundation ditch surrounding buildings thing sedimentation of direct guidance for solving regional bulk settling or agricultural production.
In addition, the domestic water that simultaneously descends at deep foundation pit precipitation recharges, case history itself is actually rare, and in the various references groundwater recharge control technology is put down in writing seldom, to how regulating control effectively recharge flow, recharge the pressure aspect, not proposing effective measure, is to belong to gravity flow to recharge basically, and effect is recharged in very difficult assurance.
Two, the necessity of groundwater recharge
1, technology necessity:
It is more and more general to carry out deep foundation pit construction around intensive building.In this case, not only to consider the foundation pit dewatering problem, also to consider owing to excessive precipitation causes the uneven subsidence of foundation ditch surrounding soil or original building, otherwise can cause soil mass of foundation pit or existing building thing crack, member fracture even structural collapse.In addition, if the underground water of smoking is not in a large number recharged, also can cause a large amount of wastes of freshwater resources.
2, economic necessity:
For excessive loss does not take place underground water in preventing on foundation ditch surrounding soil or the original building ground, way has two: the one, around foundation ditch, adopt the mode of cement mixing pile water-stop curtain, and prevent that underground water from flowing into foundation ditch; The 2nd, adopt the groundwater recharge method, in soil layer, form a reversing cone of depression opposite with the precipitation well point, make the radius of influence of precipitation well point be no more than the scope of recharging the well point, groundwater table is remained unchanged substantially, soil layer pressure still is in the original equilibrium state, thereby prevents that effectively the precipitation well point is to the influence of building on every side.
Engineering practice shows, adopt the recharge well scheme than cement mixing pile economy many, reach 35%～45%, still, when adopting the groundwater recharge method, the control of recharging effect is had relatively high expectations.
Summary of the invention
The object of the present invention is to provide a kind of underground water recharging, regulating and controlling device simple in structure, regulatable.
To achieve these goals, the technical solution used in the present invention is: underground water recharging, regulating and controlling device, it comprises collecting well, the water inlet person in charge, water inlet arm, recharge well, the input that water inlet is responsible for is connected with collecting well, the output that water inlet is responsible for is connected with the input of a plurality of water inlet arms respectively, and the output of each water inlet arm is connected with corresponding recharge well; It is characterized in that: be embedded with telescopic pipe in the recharge well, telescopic pipe is imbedded underground 500mm and is had weep hole with the lower part; The output of water inlet arm is positioned at the bottom of telescopic pipe; Water inlet is responsible for and is provided with force (forcing) pump, is responsible for valve, main flow meter; Each water inlet arm is provided with arm valve, shunt volume meter.
The present invention is by setting up telescopic pipe, and is provided with force (forcing) pump on water inlet is responsible for, is responsible for valve, main flow meter; Each water inlet arm is provided with the arm valve, equipment and instrument such as shunt volume meter, make the whole device that pipeline forms similar " syringe " that recharges, regulate and control recharge water pressure and flow by force (forcing) pump and valve, also can be according to flow meter and manometric reading, draw and recharge pressure, recharge the relation of flow and soil permeability coefficient, accomplished under the situation that does not increase expense, need much design discharges just can reach the effect of much flows, changed and just taked gravity flow to recharge at present, recharge the Passive Control present situation that effect is difficult to guarantee, play the initiatively effect of regulation and control.
The invention has the beneficial effects as follows:
1, not high, practical to geology hydrological data data accuracy requirement.
To some recharge well, may since soil layer recharge transmission coefficient or pervious layer thickness is less, under the situation that gravity flow is recharged, actual water recharge capacity (flow) is less than the design water recharge capacity when (flow), at this moment do not need to consider that actual geological hydrology condition recomputates the adjustment design and recharges flow, but recharge hydraulic pressure in the increase recharge well, and increase the actual flow that recharges, allow it still reach former design and recharge flow.
Use this regulation device, only need to regulate the valve (the adjustable flow that recharges) on the arm of respectively intaking, to needs supercharging and self-flow recharging well, what all can meet design requirement recharges flow, practical.
2, apparatus structure is simple, and is with low cost.
This device only needs (or some, decide on a recharge well quantity) force (forcing) pump and some valves, flow meter, pressure meter and water pipe to get final product, and many wells can a shared pump, and is with low cost.
3, construction, test are carried out simultaneously, can draw some important geology hydrologic parameters easily, for the similar engineering construction is accumulated experience.
In pressure process, can draw the relation curve that soil recharges flow and osmotic pressure at an easy rate by the reading on pressure meter and the flow meter, recharge transmission coefficient thereby draw easily.
4, can effectively realize falling the filling balance, groundwater table is remained unchanged substantially, soil layer pressure still is in the original equilibrium state before and after precipitation, thereby has controlled the sedimentation of foundation ditch surrounding soil or existing building thing.
