Abstract
The utility model provides a pit drainage structure, which comprises a submersible sewage pump (1) arranged in an indoor pit, wherein the outlet of the submersible sewage pump (1) is connected with the inlet of a water outflow pipe (2); the outlet of the water outflow pipe (2) is introduced into an outdoor drainage inspection well; and the center elevation of the water outflow pipe (2) protruding out of the room is higher than the elevation of the highest water level of the outdoor drainage inspection well. The pit drainage structure can effectively obviate the possibility that the water accumulated in the outdoor drainage inspection well flows back to the indoor pit and can prevent the occurrence of poor drainage of the submersible sewage pump by changing the pipe elevation when the water outflow pipe of the submersible sewage pump protrudes out of the axis of a building. The pit drainage structure also has the advantages of simple structure, convenient construction and the like, and has good promotion value.
Description
Technical field
The utility model relates to a kind of construction drainage structure, is a kind of melt pit discharge structure specifically.
Background technology
At present, when the indoor peak level that needs the melt pit of draining is lower than the outdoor drainage absolute altitude, general treating method is with proof submersible sand discharging pump the water in melt pit pressurization to be promoted, and drains into outdoorly, and the outdoor section of submersible sewage water pump outlet pipe generally is that level inserts the outdoor drainage manhole.When the peak level absolute altitude of outdoor drainage manhole was lower than the outdoor section absolute altitude of submersible sewage water pump outlet pipe, the water in the melt pit can promote by proof submersible sand discharging pump and send smoothly; When the peak level absolute altitude of outdoor drainage manhole is higher than the outdoor section absolute altitude of submersible sewage water pump outlet pipe, can cause the proof submersible sand discharging pump impeded drainage on the one hand, ponding in the outdoor drainage manhole may flow backwards and enter melt pit on the other hand, causes unnecessary pollution.
The utility model content
Technical problem to be solved in the utility model just provides simple, the rational melt pit discharge structure of a kind of compact conformation, overcomes the deficiencies in the prior art.
In order to address the above problem, the utility model provides a kind of melt pit discharge structure, proof submersible sand discharging pump 1 is arranged in indoor melt pit, the outlet of proof submersible sand discharging pump 1 is connected with the inlet of outlet pipe 2, the outlet of outlet pipe 2 feeds the outdoor drainage manhole, and outlet pipe 2 passes the peak level absolute altitude that outdoor tube hub absolute altitude is higher than the outdoor drainage manhole.
The outlet of proof submersible sand discharging pump 1 is connected by fabric hose 3 with outlet pipe 2.
Turn down the center absolute altitude of outlet pipe when outlet pipe 2 goes out building axis line with 90 ° of elbows, adjusted outlet pipe center absolute altitude and outdoor drainage manhole the peak level absolute altitude identical.
Compared with prior art, the utility model is by the variation at submersible sewage water pump outlet pipe pipeline absolute altitude when going out building axis line, effectively avoid the possibility of melt pit in the ponding refluence inlet chamber in the outdoor drainage manhole, can not cause the proof submersible sand discharging pump impeded drainage simultaneously.That the utility model also has is simple in structure, be convenient to superiority such as construction, has excellent popularization and is worth.

Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Embodiment: proof submersible sand discharging pump 1 is arranged in indoor melt pit, and the outlet of proof submersible sand discharging pump 1 is connected by fabric hose 3 with outlet pipe 2; The outlet of outlet pipe 2 feeds the outdoor drainage manhole, and outlet pipe 2 passes the peak level absolute altitude 0.3m that outdoor tube hub absolute altitude is higher than the outdoor drainage manhole.Turn down the center absolute altitude of outlet pipe when outlet pipe 2 goes out building axis line with 90 ° of elbows, adjusted outlet pipe center absolute altitude and outdoor drainage manhole the peak level absolute altitude identical.
