Background
In the underground engineering construction, the deep foundation pit engineering is one of the key points in the whole engineering, and the foundation pit pumping and drainage construction technology is the key point of the deep foundation pit engineering.
In engineering, a submersible pump is generally used for pumping water and is connected with a water pumping and draining pipeline, for example, a patent with the publication number of CN209703536U discloses a siphon water pumping and draining combined device for a foundation pit of a water transportation engineering. However, in the prior art, the pipe diameter of the pumping and drainage pipeline is generally set according to experience or calculation of the maximum flow, and a more reasonable design is not performed according to the actual flowing water quantity of the pipeline, so that engineering investment waste is caused due to the fact that part of the pipelines have too large pipe diameters, or the flow rate in the pipelines is too large due to the fact that the pipe diameters are insufficient, power consumption is increased, and the precipitation effect is influenced.
Disclosure of Invention
The utility model aims at providing a drainage pipeline device is taken out to foundation ditch, drainage branch's pipe diameter is confirmed according to the volume of drinking water of single downcast pipe well, and each section collecting main's pipe diameter is confirmed according to the catchment volume of flowing through this section collecting main, avoids appearing the too big or not enough problem of pipe diameter.
The utility model discloses a technical scheme be a drain pipe device is taken out to foundation ditch, include: the submersible pump is placed in the dewatering pipe well, one end of each drainage branch pipe is connected with the submersible pump, the other end of each drainage branch pipe is connected with the water collecting main pipe, and the pipe diameters of all sections of the water collecting main pipes are different.
Preferably, the pipe diameter of the branch drain pipe is determined according to the pumping capacity of a single downcomer well.
Preferably, the pipe diameter of each section of water collecting main pipe is determined according to the water collecting amount flowing through the section of water collecting main pipe.
Preferably, the drainage branch pipe is connected with the water collecting main pipe through a reducing tee.
Preferably, the joints of the reducing tee joints, the drainage branch pipes and the water collecting main pipe are fixed by clamps.
Preferably, the water collecting main pipe is connected with the water collecting tank.
The beneficial effects of the utility model reside in that: the pipe diameter of the drainage branch pipe is determined according to the water pumping quantity of a single downcast well, and the pipe diameter of each section of the header pipe is determined according to the water collecting quantity flowing through the section of the header pipe, so that the phenomena that the engineering investment is wasted due to overlarge pipe diameter, or the power consumption is increased and the downcast effect is influenced due to overlarge flow velocity in the pipeline due to insufficient pipe diameter are avoided; the drainage branch pipe is connected with the water collecting main pipe through the reducing tee, and the joints of the reducing tee, the drainage branch pipe and the water collecting main pipe are fixed through the clamps, so that the stability of the device is enhanced; the pipes of the drainage branch pipe and the water collecting main pipe are made of steel pipes, so that the power loss in the drainage process can be reduced, the foundation pit dewatering efficiency is further improved, and the foundation pit drainage system has stronger impact resistance and longer service life; simple structure, convenient construction, low cost and good social and economic benefits.
