Abstract
The utility model relates to a dewatering well, in particular to a direct-insertion dewatering well made of light steel pipes, which is suitably used for lowering groundwater level at a medium and high speed during project construction. The bottom section of the direct-insertion dewatering well made of the light steel pipe takes a sharp cone shape; the sharp cone well body at the bottom section is provided with holes for leaking water; the top of the well body is connected with a water inlet of a water pump through a connection pipe; a water outlet of the water pump is connected with a water discharging pipe. The utility model provides a novel dewatering well that has simple structure, low cost, short construction period, high efficiency and low requirement for construction sites.
Description
Technical field
The utility model relates to a kind of precipitation well, is specially direct insertion light steel tube precipitation well, is applicable to the usefulness of fast speed dewatering in the engineering construction.
Background technology
In the middle of building, municipal engineering construction, when excavation basis or tunnel, the aquifer of soil layer is cut off, underground water can constantly infiltrate in the foundation ditch, for normally carrying out of guaranteeing to construct, prevent drift sand, side slope unstability and bearing capacity of foundation soil and descend, must reduce the groundwater table of construction area.The mode that present precipitation well adopts is the deep-well that spuds in out, for preventing that the borehole wall from collapsing the polylith cement circle of precoating need be set in the down-hole, the hoistway moulding is thrown in submersible pump later on underground water is extracted out, make groundwater table decreasing, such way shortcoming is: because need put down submersible pump, require well diameter enough big; Construction is complicated, occurs the borehole wall easily in the large diameter wellhole cutting process and collapses, and the cement circle of precoating prevents difficulty; Whole precipitation well construction complexity breaks down easily; Precipitation well construction complexity makes the duration very long; Such precipitation well is to the site requirements height; Whole precipitation well with high costs.
Summary of the invention
The utility model is just in order to solve above technical problem, provide a kind of simple in structure, with low cost, the duration is short, efficient is high, to the less demanding novel precipitation well in construction plant.
Concrete technical scheme of the present utility model is as follows:
Direct insertion light steel tube precipitation well, comprise well casing body 1 and suction pump 2, connecting pipe 3, outlet conduit 4, the end section of the well casing body of being narrated 1 is the pointed cone type, offer permeable hole 5 on the well casing body of section pointed cone position, the end, the top of well casing body is connected with the inlet opening of suction pump 2 by connecting pipe 3, and the delivery port of suction pump 2 is connected with outlet conduit 4.
Well casing body 1 hollow.
Connecting pipe 3 is provided with and opens and closes valve 6.
During use, vertically insertion is underground with well casing body 1, and permeable hole 5 is lower than after the phreatic line, opens to open and close valve 6, and suction pump 2 work will go out the face of land by the water pump that permeable hole 5 infiltrates well casing bodies 1, gradually dewatering.
Show the following aspects by implementing the later good effect of the utility model:
Because do not need to put down submersible pump, so do not need to dig the large aperture wellhole
Construction is simple, because of well casing body hollow, promptly forms Jing Dong when the well casing body is deep downwards, technical problems such as the borehole wall collapses can not occur.
Whole precipitation well construction is simple, is not easy to break down
The precipitation well construction simply makes the duration shorten significantly.
This precipitation well construction is simple, and use can be withdrawed from repeated use after finishing, and the materials demands such as cement circle of not precoating are with low cost.
The precipitation well is not high to site requirements, is fit to many occasions and uses.
Description of drawings
Fig. 1 is a structural representation of the present utility model, wherein:
1---body
2---suction pump
3---connecting pipe
4---outlet conduit
5---permeable hole
6---open and close valve
The specific embodiment
The utility model is described in further detail below in conjunction with the specific embodiment and description of drawings,
Direct insertion light steel tube precipitation well, comprise well casing body 1 and suction pump 2, connecting pipe 3, outlet conduit 4, the end section of the well casing body of being narrated 1 is the pointed cone type, offer permeable hole 5 on the well casing body of section pointed cone position, the end, the top of well casing body is connected with the inlet opening of suction pump 2 by connecting pipe 3, and the delivery port of suction pump 2 is connected with outlet conduit 4.
Well casing body 1 hollow.
Connecting pipe 3 is provided with and opens and closes valve 6.
During use, vertically insertion is underground with well casing body 1, and permeable hole 5 is lower than after the phreatic line, opens to open and close valve 6, and suction pump 2 work will go out the face of land by the water pump that permeable hole 5 infiltrates well casing bodies 1, gradually dewatering.
The suitable well casing body in the bottom of pointed cone type downwards deeply, permeable hole is lower than after the phreatic line, underground water is in permeable hole flows into the well casing body, under the effect of suction pump, form negative pressure in the well casing body, the underground water that infiltrates in the well casing body is raised out ground surface, and the work by suction pump is to reach the dewatering line.
