Abstract
The utility model relates to a facility for lowering underground water level in civil construction fields, which particularly relates to a recoverable percussion drill steel pipe dewatering well. The recoverable percussion drill steel pipe dewatering well is formed by standard steel pipe segments (1) which are connected through welding an adjacent pipe well end, the numbers of the standard steel pipe segments (1) are two-four, and the recoverable percussion drill steel pipe dewatering well is vertically arranged underground, the upper end (2) of a dewatering well and the lower end (3) of the dewatering well are opened, and the lower end (3) of the dewatering well is provided with a diving pump 4.
Description
Technical field
The utility model relates to dewatering facility in the middle of the civil engineering ground, is specially a kind of recoverable Churn drill steel pipe precipitation well.
Background technology
Precipitation is meant and utilizes the hydrogeology principle, by phreatic water levels such as the perched water in precipitation facility eliminating surface water body or the reduction stratum, divings, satisfies the precipitation depth and the time requirement of construction work.When the foundation dredging of building operations, beneath pipeline operation, all need artificial dewatering, general facilities is for offering bright row and pipe well, pipe well is exactly around deep foundation ditch etc. needs the construction ground of dewatering the well casing that is deeper than substrate to be set, underground water is extracted out underground water by the submersible pump that is arranged in the well casing, thereby made groundwater table be lower than the end, hole.Present precipitation pipe well is by digging the cement pipeline section that bigbore Jing Dong places single section 2.5 meters long one by one, form the cement pipe well of 300 millimeters of internal diameters, though the shaft bottom submersible pump only needs 245 millimeters hole diameter, but because the cement pipe well is a cement prefabricated component, its specification is coarse, at least the cement pipe well that needs in the middle of the practice of construction to be made into 300 millimeters of internal diameters could be placed the shaft bottom submersible pump, adds the thickness of cement pipe well self tube wall, and the needed well hole dia of whole cement precipitation well is very big.Prefabricated cement well casing section is confined to 2.5 meters because make reason, and disconnected list cuts the well casing section repeatedly to be pieced together knot and also prolonged the construction period, and the thick and heavy transportation of prefabricated in addition cement well casing body is installed and all shown inconvenience.It is long in time limit that large diameter Jing Dong consumes in the cutting process, and the sinking shaft difficulty is big, and sinking cost is with high, and so the cost cost of precipitation well is about 80 ~ 130 yuan.Such precipitation well can not be extracted repeated use because the cement tube wall of laying is disposable, more makes the integral body of precipitation well become the local exchange height not down, becomes permanent civil engineering excavation obstacle underground leaving over after the precipitation well uses simultaneously.
Summary of the invention
The utility model is just at above technical problem, and purpose is to provide a kind of recoverable Churn drill steel pipe precipitation well, realizes low cost, casual labourer's phase, small-bore cutting.
The technical solution of the utility model is as follows:
Recoverable Churn drill steel pipe precipitation well, form by standard steel pipeline section (1) by recoverable Churn drill steel pipe precipitation well casing body, facing the tube wall end mutually by welding between the standard steel pipeline section (1) connects, the quantity of standard steel pipeline section (1) is 2 to 4, recoverable Churn drill steel pipe precipitation well is vertically set on underground, the aboveground end of precipitation (2), precipitation downhole end (3) are opened, and precipitation down-hole (3) end is provided with submersible pump 4.
The internal diameter of standard steel pipeline section (1) is 245 millimeters.
The single tube length of standard steel pipeline section (1) is 6 meters.
The material of standard steel pipeline section (1) is an iron and steel.
The utility model recoverable Churn drill steel pipe precipitation well is equally dug Jing Dong with traditional pipe of cement precipitation well, but the well hole dia is little a lot, thereby wide open cutter time of well and the wide open cutter difficulty of well have been reduced significantly, the recoverable Churn drill steel pipe precipitation well casing body that after the wide open cutter of well 2 to 4 root beads is connected into type is placed in the middle of the well hole, submersible pump is set in the down-hole carries out the precipitation operation.Groundwater table is reduced to after the degree of requirement of engineering, at first takes out submersible pump, recoverable Churn drill steel pipe precipitation well casing body integral body is extracted to get final product then from the well hole.Recoverable Churn drill steel pipe precipitation well casing body can repeatedly use repeatedly, promptly avoids occurring civil engineering excavation obstacle to carrying out backfill with Jing Dong.
Show by implementing good effect of the present utility model:
1, recoverable Churn drill steel pipe precipitation well well hole dia is little, has reduced wide open cutter difficulty of well and cost, has shortened the construction period.
2, recoverable Churn drill steel pipe precipitation well casing body material is light, is convenient to transportation and construction.
3, the down slotting Jing Dong of recoverable Churn drill steel pipe precipitation well casing body one piece has shortened the construction period.
4, steel pipe precipitation well casing body can use repeatedly, and the single depreciation cost is low to moderate 5 yuan/meter, has reduced the dewatering project cost.
5, civil engineering excavation obstacle can be avoided forming in the well hole behind the pumpback steel pipe precipitation well casing body.
6, steel pipe precipitation well casing body internal diameter is smooth evenly is convenient to place submersible pump.
