Description
Technical field
The utility model belongs to equipment manufacturing technology field, particularly a kind of excavation of foundation pit water-level control apparatus.
Background technology
In construction of hydro project process, the problem usually run into is that underground water table is too high, affects engineering foundation excavation, relatively large distribution structure, entrance gate engineering etc. on the cross project in water station engineering as darker in basis, trench drain, feed ditch.If water lev el control does not reach the required degree of depth, the quality requirements that engineering foundation is constructed just can not be ensured.Safe and reliable good execution conditions are possessed in order to make hydraulic engineering etc.; guarantee the normal operation of existing hydraulic structure; effectively conservation of nature environment, prevent underground water from working the mischief; in work progress; must for concrete situation; take appropriate measures, effectively underground water is controlled.
Summary of the invention
For solving the defect that works the mischief to construction work of underground water that prior art exists, the utility model provides a kind of excavation of foundation pit water-level control apparatus, effectively solves the problem that construction work that underground water causes is difficult to carry out.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of excavation of foundation pit water-level control apparatus, comprise water level controller, drainpipe, filter pipe, water pump and recovery pond, it is characterized in that: what described water level controller was connected by cable has cable float switch, described cable float switch is arranged at inside filter pipe, described water pump to be arranged on outside filter pipe and to be connected with described filter pipe and drainpipe by a drinking-water pipe, and described drainpipe is connected with described recovery pond.
Preferably, between described water level controller and water pump, A.C. contactor is set.
Preferably, described cable is high flexibility cable.
Preferably, described cable float switch is metallic cable float switch.
Preferably, described cable float switch adopts mercury cut-off as contact part.
Preferably, described filter pipe is the cement pipe of diameter 300mm.
The beneficial effect of employing technique scheme is:
1. structure of the present utility model is simple, reasonable in design, installation is also very convenient, by arranging water level controller and cable float switch controls the water level in filter pipe, after the water level in filter pipe reaches controlling water level line, water can be extracted in drainpipe by water pump, and then centralized recovery is in recovery pond, recycle, such structural design effectively solves the defect that too high the caused construction work of groundwater level is difficult to carry out.
2. the effect arranging A.C. contactor between water level controller and water pump is as overload, prevents float switch from burning out because of reasons such as electric current superelevation.
3. what water level controller was connected by cable has cable float switch, cable is high flexibility cable, cable float switch is metallic cable float switch, cable float switch adopts mercury cut-off as contact part, and the feature of design is like this that float switch is applicable to the occasions such as sewage, and resistance to chemical attack, high temperature resistant, durable in use, economy is high, and serviceable life also improves greatly.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, specific embodiment of the utility model is described in detail.
Fig. 1 is the structural representation of a kind of excavation of foundation pit water-level control apparatus of the utility model;
