Description
Technical Field
The utility model belongs to the technical field of building construction foundation pit dewatering, concretely relates to an automatic device for elevator well pit dewatering.
Background
In building construction, foundation pit dewatering is an essential step. Usually, large-area precipitation is carried out before foundation construction so as to ensure the dryness of a foundation working surface. However, if the number of building layers is not high and the groundwater level is deep, large-area precipitation can be converted into local precipitation for saving cost. For example, when the water in part of the elevator pit is reduced, the water collecting pit can be arranged in the elevator pit, and then the water collecting pit is used for local water reduction to achieve the purpose of integral water reduction.
At present, when local precipitation is carried out by utilizing an elevator well pit, constructors put a water pump in the water collecting pit directly and then pump water at regular time. The method has the great disadvantage that if the underground water level rises too fast, the water easily flows back into the elevator shaft pit, and if the underground water level rises slowly, the water pump is easily exposed in the air to work and is burnt.
Disclosure of Invention
The utility model discloses a solve and utilize the elevator well hole to carry out local precipitation and lack effective device at present, cause the elevartor shaft to flow backward or the problem that the water pump burns out easily, provide an automatic device for elevator well hole precipitation.
The utility model discloses a realize through following technical scheme: the utility model provides an automatic device for elevator well pit dewatering, including the precipitation bucket, the precipitation bucket sets up in the sump pit, the sump pit is located below the horizontal plane of elevator well pit, the precipitation bucket is bottom open-ended hollow cylinder structure, the precipitation bucket adopts stainless steel, the precipitation bucket includes the staving, evenly laid a plurality of through-holes on the staving, the top of staving is provided with the bung, it is provided with drinking-water pipe and water level inductor to be located precipitation bucket inside, the drinking-water pipe is connected with the one end of self priming pump, the other end of self priming pump is connected with the drain pipe, the tip setting of drain pipe is in foundation ditch top escape canal, the water level inductor is connected with opening and closing that the self priming pump is used for controlling.
Furthermore, two sleeves are vertically arranged at the top of the barrel cover, one sleeve is a water pumping pipe positioning sleeve, the other sleeve is a water level sensor placing opening, and the water pumping pipe positioning sleeve and the water level sensor placing opening are communicated with the inside of the precipitation barrel.
Further, the water level sensor is a water level gauge or a ball float valve.
The utility model discloses a theory of operation is:
firstly, excavating a water collecting pit at a position lower than an elevator well pit, paving broken stones at the bottom of the water collecting pit after the water collecting pit is finished, and then placing a precipitation bucket with an opening at the bottom in the water collecting pit; further, fill the rubble around the precipitation bucket with the space of sump pit, guarantee that groundwater can see through the rubble clearance inside from the bottom and the lateral wall inflow staving of precipitation bucket, the inside water level inductor of precipitation bucket is used for predetermineeing the bucket internal water level value. When the water level reachd predetermined water level value, the self priming pump starts, takes out the water that gets into the precipitation bucket to foundation ditch top escape canal through the drinking-water pipe, finally realizes the precipitation purpose.
Compared with the prior art, the utility model beneficial effect who has is:
the utility model relates to a rationally, can realize opening and closing of self priming pump automatically through the water level inductor to get rid of unnecessary groundwater in the sump pit, reach the effect of local precipitation. The utility model discloses the use of device has effectively reduced personnel's on duty cost, has also stopped simultaneously that groundwater flows backward the foundation ditch and because the self priming pump burns the damage that leads to futilely.
