Abstract

The utility model belongs to the technical field of devices for lowering groundwater level when in foundation construction of construction engineering, in particular to a well plugging device of a dewatering well. The well plugging device solves the problem that plugging quality hidden danger can be caused by the existing method for sealing a dewatering well, or the dewatering well can not be plugged when the groundwater pressure or water inflow is bigger. The well plugging device of a dewatering well comprises a steel sleeve which is sleeved on the upper portion of a well pipe of the dewatering well and a steel cover plate which is arranged on the top portion of the steel sleeve. The utility model is characterized in that the steel sleeve and the steel cover plate are connected through a flange, a rubber cushion is arranged between the contact surfaces of the connecting portion, a water conduit is threaded on the steel cover plate, the lower end of the water conduit is inserted in the steel sleeve, and the upper end of the water conduit is equipped with a valve. The utility model has the advantages of adopting the construction method of adopting the valve to plug the dewatering well, the dewatering well is firstly closed, which secondly guides water, groundwater is changed from being plugged to be conducted, and the water gushing problem is solved when water is plugged, and quality hidden danger is not left in the process of plugging a dewatering well, and the construction is easily operated.

Description

Precipitation well shut-in well device
Technical field
Dewatering was specifically related to a kind of precipitation well shut-in well device with the technical field of device when the utility model belonged to the construction work foundation construction.
Background technology
During the construction work foundation construction, often adopt deep-well to reduce underground water, need after construction is finished the precipitation well with concrete or fill out the rubble sealing.During water level lowering well sealing such as groundwater pressure and water yield less, then can be directly in well concreting or fill out rubble, then with steel deck-plate and precipitation casing welded closure, the construction way is seen accompanying drawing 1, is the method for first water blockoff rear enclosed.
As groundwater pressure or water yield when big, even built concrete in the precipitation casing, because underground water oozes out very soon, or water pump also do not take out underground water fully and just has been full of the shut-in well sleeve pipe, causes shutoff welding quality hidden danger or can't shutoff.
Summary of the invention
The utility model is in order to solve groundwater pressure or water yield when big, and the method for existing water level lowering well sealing may cause shutoff hidden danger of quality or problem that can't shutoff, and a kind of precipitation well shut-in well device is provided.
The utility model adopts following technical scheme to realize: a kind of precipitation well shut-in well device, comprise the steel deck-plate that steel sleeve that precipitation well well casing top is sheathed and steel sleeve top are provided with, the connected mode that it is characterized in that steel sleeve and steel deck-plate is that flange is connected, between the contact surface of junction rubber pad is set, wear aqueduct on the steel deck-plate, insert in the steel sleeve aqueduct lower end, aqueduct upper end mounted valve.Fill out rubble in the aqueduct altitude range in the steel sleeve.
The relative prior art of the utility model has following beneficial effect: the method that adopts valve shutoff precipitation well construction, seal the back water guide earlier, underground water is led by stifled becoming, and the water burst problem when having solved shutoff makes precipitation well shutoff process not stay hidden danger of quality and construct easy to operate.
Description of drawings
Fig. 1 is existing precipitation well enclosure method schematic diagram
Fig. 2 is the utility model structural representation
Fig. 3 is the I-I sectional drawing of Fig. 2
Among the figure: the 1-field welding, the 2-steel deck-plate, the 3-steel sleeve, the 4-seal ring, the 5-base concrete, 6-adds coiled material, and 7-foundation pad and waterproof are rubbed, 8-dry patching mortar, 9-well casing, 10-rubble, 11-valve, 12-rubber pad, 13-bolt, 14-aqueduct
The specific embodiment
In conjunction with the accompanying drawings the specific embodiment of the present utility model is described further, embodiment is used for illustrating of the present utility model, rather than it is imposed any restrictions.
A kind of precipitation well shut-in well device comprises the steel deck-plate 2 that steel sleeve 3 that precipitation well well casing 9 tops are sheathed and steel sleeve 3 tops are provided with, and the connected mode that it is characterized in that steel sleeve 3 and steel deck-plate 2 is that flange is connected, and rubber pad 12 is set between the contact surface of junction.Wear aqueduct 14 on the steel deck-plate 2, insert in the steel sleeve 3 aqueduct 14 lower ends, aqueduct 14 upper end mounted valves 11.Aqueduct 14 can in time be discharged the water in the steel sleeve 3.
Precipitation well steel sleeve can concreting below 3 or is filled out rubble, fills out rubble in aqueduct 14 altitude ranges in the steel sleeve 3 and is beneficial to draining.
In the work progress, after rubble fills up in the steel sleeve 3, be about to steel deck-plate 2 and be connected with steel sleeve 3 usefulness bolts 13, the valve 11 at aqueduct 14 tops is opened, and for preventing infiltration, 3 of steel deck-plate 2 and steel sleeves are provided with rubber pad 12, and bolt 13 is tightened.Bolt 13 is tightened the back valve-off, treats after 24 hours to check that leakproof is qualified, otherwise will check reason and reinstall, until qualified.Build top protection concrete pier base then, the pier size can be selected circular or square according to casing diameter.
