Abstract
The utility model relates to a composite dewatering device of a vacuum tube well, and can effectively solve the problem of difficulty in drainage of perched water, saturated water in cohesive soil of an aquiclude and residual water on the boundary of a water-containing layer. According to the technical scheme for solving the problem, the composite dewatering device comprises a well tube, a vacuum pump, a submersible pump, a drainage pipe and a water pump, and is characterized in that: the well tube is arranged below the ground; the lower part in the well tube is provided with the submersible pump which is hoisted through a steel wire placed on the ground; the submersible pump is connected with a power supply on the ground through a cable; a water outlet of the submersible pump is connected to the water pump on the ground through the drainage pipe; a sealing device is arranged on a wellhead of the well tube; a vacuum pipe which is connected with the vacuum pump is arranged in the port on the well tube; and a vacuum gauge extends deep into the well tube through the wellhead sealing device. The composite dewatering device has the advantages of simple structure, safety, reliability, low construction cost, capabilities of effectively shortening construction period, improving the safety for civil engineering construction, improving the construction environment, quickening the construction progress and saving a large amount of investment in manpower and material resources, and good economic benefit and social benefit.
Description
Technical field
The utility model relates to building implements, particularly a kind of vacuum tube well composite water-reducing device.
Background technology
The continuous quickening of urban development process has promoted the develop rapidly of urban rail transit construction.Subway is all being built energetically in each metropolis, the whole nation.But in the subway construction process, saturation water and interface, aquifer residual water in perched water, the aquitard cohesive soil adopt present conventional equipments such as pipe well to be difficult to drain, and vacuum-dewatering device commonly used receives multiple factor affecting, can't be applied.
Summary of the invention
To above-mentioned situation; For overcoming the defective of prior art; The purpose of the utility model just provides a kind of vacuum tube well composite water-reducing device, can effectively solve saturation water and interface, aquifer residual water in perched water, the aquitard cohesive soil, the problem that is difficult to drain.
The technical scheme that the utility model solves is; Comprise well casing, vacuum pump, submersible pump, gutter and suction pump, it is characterized in that well casing places below ground; In the well casing there be through placing the submersible pump of ground steel wire lifting the bottom; Submersible pump joins through cable and ground power supply, and the delivery port of submersible pump connects through gutter and places ground suction pump, and there is sealing device at the well head place of well casing; The well casing upper oral part is built-in with the vacuum tube that connects vacuum pump, and vacuum meter is in well mouth sealing device is deep into well casing.
The utility model is simple in structure, safe and reliable, construction cost is low, effectively reduction of erection time, raising civil works are built safety; Improved construction environment; Accelerating construction progress is practiced thrift a large amount of manpower and materials inputs, has good economic benefit and social benefit.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Elaborate below in conjunction with the specific embodiment of accompanying drawing to the utility model.
By shown in Figure 1; The utility model comprises well casing, vacuum pump, submersible pump, gutter and suction pump, it is characterized in that, well casing 1 places ground below 13; In the well casing 1 there be through placing the submersible pump 3 of ground steel wire 2 liftings the bottom; Submersible pump 3 joins through cable 4 and ground power supply, and the delivery port of submersible pump connects through gutter 5 and places ground suction pump 6, and there is sealing device 7 at the well head place of well casing; The well casing upper oral part is built-in with the vacuum tube 9 that connects vacuum pump 8, and vacuum meter 12 is deep in the well casing through well mouth sealing device 7.
Described well casing 1 comprises urceolus 10 and chimney filter 11, between urceolus and chimney filter filtrate is housed.
The valve 14 that is used to control draining is housed on the described gutter 5.
The valve 15 that control vacuumizes is housed on the described vacuum tube 9.
Increase sealing device at the primary tube well construction, outer chains is connected to vacuum pump, quickens pump drainage underground water through the negative pressure that vacuum pump forms in pipe well, and negative pressure of vacuum can also produce active force, drainage underground water to the underground water in the stickiness soil layer of poor permeability simultaneously.Vacuum plant and tube well dewatering device are two cover independent device, and suction pump and vacuum pump can independently be launched, and be effectively energy-conservation.The utility model is simple in structure, safe and reliable, and construction cost is low, and effectively reduction of erection time, raising civil works are built safety, and this device is used widely in subway construction construction and all kinds of construction of tunnel.
