Abstract
The invention relates to a device utilizing precipitation well groundwater in a watery sand layer for construction on the building site, which comprises a water pump, a water supply pipe and a controller. The device is characterized in that a precipitation well is dug in the watery sand layer on the building site, and the water pump is installed in the precipitation well. After connected with a fine filter through a water pipe, the water pump is connected with a water tank which is connected with a water outlet pipe, the water outlet pipe is connected with a water supply pump, one branch pipe of the water outlet pipe is connected with a filter, and another branch pipe where a valve is installed is connected with a construction position of the building site through a water pipe. The device is further characterized in that a water level sensor is installed in the water tank, a pressure meter is connected with the controller which is connected with the water pump, and the distance between the water pump installed in the precipitation well and the bottom of the precipitation well is at least 1.5 m. The device has the advantages of fully utilizing groundwater of the building site, saving urban water, and avoiding the trouble that the groundwater needs to be pumped and drained in construction of the building site simultaneously.
Description
Technical field
The present invention relates to a kind of device that utilizes precipitation well underground water in the watery layer of sand to be used for site construction.
Background technology
AT STATION, in the shield-tunneling construction process, the water that water for building uses water-supply systems to provide basically.Present requirement is satisfied in the present supply of water-supply systems basically, if but provide also will for station, shield-tunneling construction, it provides water supply volume not necessarily can satisfy construction requirement, and cost is higher.And other in the watery layer of sand of the south of the lower reaches of the Yangtze River, abundant underground water is arranged, in construction, also need carry out pump drainage now and handle underground water.Therefore if can make full use of underground water; Be used for construction through a corresponding control device part, a part is used for Office Area and living area water, will save production cost greatly; Also practice thrift urban water use, therefore demanded developing the technology of groundwater use in the watery layer of sand urgently.
Summary of the invention
The objective of the invention is a kind of construction equipment that underground water recycles in the watery layer of sand that utilizes, to solve existing building site problem of water consumption.The present invention designs a kind of device that utilizes precipitation well underground water in the watery layer of sand to be used for site construction, comprises water pump, feed pipe, controller, it is characterized in that: dig in the watery layer of sand in the building site and be provided with the precipitation well; In the precipitation well, water pump is installed; Water pump connects water tank after connecing fine filtrator by water pipe again, is connected with outlet pipe on the water tank, and outlet pipe connects supply-water pump; A road of outlet pipe is in charge of the connection filter for molten, and another route water pipe and mounted valve meet the site construction place.It is characterized in that: level sensor is installed in water tank, and level sensor connects controller, and controller connects water pump.It is characterized in that: pressure gauge is installed on the outlet pipe, and pressure gauge connects controller, and controller connects supply-water pump, it is characterized in that: be installed in water pump in the precipitation well apart from least 1.5 meters in the shaft bottom of precipitation well.Advantage of the present invention is the underground water that has made full use of the building site, has practiced thrift urban water use on the one hand, needs the phreatic trouble of pump drainage when also having avoided site construction simultaneously in addition.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present invention, and Fig. 2 is a precipitation well structure chart of the present invention.
The specific embodiment
Comprise supply-water pump 1, outlet pipe 2, controller 3 among the figure; It is characterized in that: dig in the watery layer of sand in the building site and be provided with precipitation well 4, water pump 5 is installed in the precipitation well, water pump connects water tank 8 after connecing fine filtrator 7 by water pipe 6 again; Be connected with outlet pipe 2 on the water tank; Outlet pipe connects supply-water pump 1, and a road of outlet pipe is in charge of and is connected filter for molten 10, and another route water pipe and mounted valve 11 meet the site construction place.It is characterized in that: level sensor 12 is installed in water tank, and level sensor connects controller, and controller connects water pump.It is characterized in that: pressure gauge 9 is installed on the outlet pipe, and pressure gauge connects controller, and controller connects supply-water pump, it is characterized in that: be installed in water pump in the precipitation well apart from least 1.5 meters in the shaft bottom of precipitation well.
(1) precipitation well water pump is installed.
In the work progress, the precipitation well is implemented.Select a streamflow more, can fully satisfy the well that the construction water yield requires.Water quality is at the visual well of no fine sand down.And the installation flow reaches 6m
3/ h is with charging pump, to the well about the following 1m of the water surface, but apart from least 1.5 meters in shaft bottom.
(2) installation of fine filtrator.
Before pumping line in the precipitation well gets into water tank, fine filtrator is installed, this fine filtrator uses metal construction, and convenient flushing can recycle.Filter the fine particle that the interior underground water that extracts of precipitation well can not be visual.Whenever check water quality in the precipitation well at a distance from 1 week simultaneously, the flushing fine filtrator.
(3) installation of the high and low fluviograph of water tank.
The high 2m of water tank, cumulative volume are 6m
3More than.In establish high and low level sensor.Simultaneously alarm lamp is set in the water tank eminence.When the water tank low water stage, when low water level sensor has signal, can provide sound, light to report to the police.
(4) total feed pipe water pump and pressure gauge are installed.
The supply-water pump of outlet pipe is for providing 6m
3The water pump that/h is above, supply construction, living area and Office Area whole construction water.And at the pressure gauge of settling the hydraulic pressure amount of outlet pipe from supply-water pump 1m place.Outlet pipe hydraulic pressure is set at 4bar.If greater than 4bar, then the water yield satisfies construction requirement in the outlet pipe, and the outlet pipe water pump can quit work.If less than 4bar, then the water yield can not satisfy construction requirement in the outlet pipe, and water pump 1 can be worked, and in water tank, extracts water, supply whole construction water.
(5) control cabinet is installed.
Control cabinet is the total install bin of electrical control, control precipitation well water pump and the high and low water level of water tank, alarm lamp work relationship.Through the pressure gauge on the outlet pipe, whether the supply-water pump on the control outlet pipe works.
(6) living area and Office Area strainer are installed.
Divide secondary to be in charge of in the outlet pipe.One is in charge of not filter and can directly be used for construction waters such as shield machine, station.One be in charge of be used for the life and the Office Area, water quality has higher requirements.The water of Office Area is used to live and after need pass through the multicore strainer.But this multicore strainer automatic fitration does not need additional power supply.Cross filter core and regularly change, to guarantee water quality according to water supply volume.
