Abstract
The utility model discloses a kind of water drainage of deep foundation pit pump antipriming, comprise drainage pump, water check valve and gutter, it is characterized in that: the delivery port of described drainage pump first installs the water check valve of an anti-non-return water, then is connected with gutter.The utility model has the advantages that structure is simple, easy to use, effectively ensure that after draining without ponding in foundation ditch, the water in drainage pump water pipe does not flow backwards, and improves foundation pit construction quality, save man-hour, reduce construction cost.
Description
Technical field
The utility model belongs to Roadbed Construction Technology field, and be a kind of water drainage of deep foundation pit pump antipriming specifically, be applicable to the draining after deep pit digging, drainage pump is when quitting work, and the water in drainage pump water pipe no longer flows backwards.
Background technology
After deep pit digging, in deep foundation ditch and basement construction process, for controlling well in foundation ditch without ponding, main use pumping drainage, and in drainage procedure, often because can not thoroughly drain the ponding in foundation ditch and affect construction, because foundation ditch is dark, aqueous reflux in drainage pump water pipe, job site comprises first uses pumping drainage, then with measures such as labor cleanings, in addition, also propose from construction technology and management the control method preventing aqueous reflux in water pump water pipe, but under current construction technology and not rigorous way to manage situation, above-mentioned preventive action often can not control the aqueous reflux in water pump water pipe effectively, the ponding in thorough clear butt hole can not be ensured, and easily cause secondary to clear up, lose time and manpower.
Summary of the invention
The purpose of this utility model is exactly the deficiency existed for prior art, and provide a kind of water drainage of deep foundation pit pump antipriming, the technical problem of solution is, in deep foundation ditch and basement construction process, and the water generation refluence phenomenon in drainage pump water pipe.
The purpose of this utility model is achieved in that a kind of water drainage of deep foundation pit pump antipriming, comprises drainage pump, water check valve and gutter, it is characterized in that: the delivery port of described drainage pump first installs the water check valve of an anti-non-return water, then is connected with gutter.
During use, the utility model is put into foundation ditch water, after draining terminates, directly take out.Due to the effect of water check valve of the present utility model, when drainage pump works, water check valve is opened, and when drainage pump quits work, water check valve is closed automatically, thus ensure that the water in gutter can not flow backwards.
Compared with prior art, the utility model has the advantages that: structure is simple, easy to use, effectively ensure that after draining without ponding in foundation ditch, the water in drainage pump water pipe does not flow backwards, and improves foundation pit construction quality, save man-hour, reduce construction cost.
Accompanying drawing explanation
Fig. 1: front view when the utility model uses.
In figure: 1, drainage pump 2, water check valve 3, gutter.
Detailed description of the invention
For further describing the utility model, below in conjunction with embodiment and accompanying drawing, the utility model is further described.
As shown in the figure, a kind of water drainage of deep foundation pit pump antipriming, comprises drainage pump 1, water check valve 2 and gutter 3, it is characterized in that: the delivery port of described drainage pump 1 first installs the water check valve 2 of an anti-non-return water, then is connected with gutter 3.
During use, the utility model is put into foundation ditch water, after draining terminates, directly take out.Due to the effect of water check valve 2 of the present utility model, when drainage pump 1 works, water check valve 2 is opened, and when drainage pump 1 quits work, water check valve 2 is closed automatically, thus ensure that the water of 3 li, gutter can not flow backwards.
