Description
Technical field
The utility model relates to a kind of open caisson precipitation device, particularly a kind of quick open caisson precipitation device.
Background technology
Open caisson precipitation is the important job practices of modern heavy construction and underground structure, and at building, road, bridge, fields such as reservoir have important effect.By the open caisson groundwater abstraction, reduce the water content of construction foundation pit soil layer, the soil layer hole is reduced and compression concretion, improve the solum horizontal drag, improve bearing capacity of foundation soil; Reduce water level, make construction area be in low wet condition, be beneficial to the carrying out of construction.
At present, construction precipitation uses the method for vacuum pump deep-well precipitation more, promptly in deep-well with vacuum catchment, water pump draws water, vacuum pump is influenced greatly by silt, when rich groundwater, vacuum pump work is easy to generate " being drowned " phenomenon.When underground water after a little while, in vacuum pump when work, produce the phenomenon of " only going out not water outlet of air ".So in the precipitation process, should be noted that groundwater table observation, when water level is lower than the water sucking mouth, down-hole, closes vacuum pump and stop pumping; When water level is higher than the water sucking mouth, down-hole, starts vacuum pump and continue to draw water.
Summary of the invention
For solve in the deep-well with vacuum catchment, water pump draws water, vacuum pump is influenced greatly by silt, when rich groundwater, vacuum pump work be easy to generate " being drowned " phenomenon, when underground water after a little while, produce the problem of " only going out not water outlet of air " during vacuum pump work, the utility model provides a kind of quick open caisson precipitation device.
The utility model is realized by following measure:
Quick open caisson precipitation device of the present utility model, comprise vacuum pump, house steward and well point pipe, its special feature is: also include the enclosed vacuum jar between house steward and vacuum pump, house steward's a end connects the well point pipe, house steward's the other end is positioned at the inside of vacuum tank, the air entry of vacuum pump is positioned at the upper end of vacuum tank, and the vacuum tank inner bottom is provided with submersible pump, and the delivery port of submersible pump is positioned at the outside of vacuum tank.
Quick open caisson precipitation device of the present utility model, the top external surface of described vacuum tank is provided with vacuum meter, and vacuum tank inwall one side is provided with water level controller.
Quick open caisson precipitation device of the present utility model is provided with flap valve in the delivery port of described submersible pump.
The beneficial effects of the utility model: add a moisture trap behind the house steward, carry out the independent discharging of air and water, vacuum pump only provides vacuum to do power, and submersible pump only carries out draining; The utlity model has simple in structure, efficient, the vacuum height, displacement is big, and is little to the vacuum pump infringement, adaptable advantage.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, vacuum pump, 2, house steward, 3, the well point pipe, 4, vacuum tank, 5, water level controller, 6, submersible pump, 7, flap valve, 8, vacuum meter.
The specific embodiment
As shown in Figure 1, quick open caisson precipitation device of the present utility model, comprise vacuum pump 1, house steward 2 and well point pipe 3, also include the enclosed vacuum jar 4 between house steward 2 and vacuum pump 1, an end of house steward 2 connects well point pipe 3, and house steward 2 the other end is positioned at the inside of vacuum tank 4, and the air entry of vacuum pump 1 is positioned at the upper end of vacuum tank 4, vacuum tank 4 inner bottom are provided with submersible pump 6, and the delivery port of submersible pump 6 is positioned at the outside of vacuum tank 4; The top external surface of described vacuum tank 4 is provided with vacuum meter 8, and vacuum tank 4 inwalls one side is provided with water level controller 5; Be provided with flap valve 7 in the delivery port of described submersible pump 6.
1 in house steward 2 and vacuum pump add a moisture trap, and moisture trap is a closed container, and the top is connected with house steward 2 and vacuum pump 1, and a submersible pump 6 is arranged at a jar bottom, and submersible pump 6 delivery ports pass to outside the jar; A flap valve 7 is established in 6 jars of out outlets of submersible pump, prevents that aqueous reflux and air from entering; Be provided with a water level controller 5(content gauge in the eliminator), when water level in the jar was lower than certain water level, submersible pump 6 quit work, and when water level was elevated to a certain water level, submersible pump 6 started drainings.
Workflow: air in the vacuum pump 1 extracting vacuum jar 4, form vacuum, the power that underground water relies on vacuum to produce is isolated from soil, import house steward 2 through well point pipe 3, enter in the vacuum tank 4, the gas of extraction is taken away by top vacuum pump 1, and water drops down onto jar below and discharged by submersible pump 6.
Embodiment
When the underground type UASB reactor of Shandong Wastewater Treatment Plant of enterprise is built, use this to invent described device and construct.
Project profile: soil property is a sandy soil, bury of groundwater 2m, foundation ditch 30m * 50m, construction depth 9m.Establish well point pipe apart from the about 1.0m in foundation ditch edge place every 1m around foundation ditch, use Φ 40, the steel pipe of 6m is done well point pipe 3.House steward 2 adopts the steel pipe of Φ 150, and house steward 2 uses the rubber tube of Φ 40 to be connected with well point pipe 3.House steward 2 is connected vacuum tank 4 top interfaces.Another interface of vacuum tank 4 tops connects vacuum pump 1, and submersible pump 6 delivery port connecting pipes in bottom are to escape canal.
Open vacuum pump 1, check not have and leak, can carry out the precipitation operation.With directly compare by vacuum pump precipitation, this precipitation device displacement obviously increases, dewatering effect is good, silt damages little to vacuum pump.
