Detailed Description
The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.
A groundwater discharge device around a working well, comprising: a water drawing pipeline 1 and a water pump. The water intake pipe 1 is used for taking up groundwater. The water pump is used for pumping water away from the water sucking pipeline 1.
Specifically, the water scooping pipe 1 itself has a cylindrical shape. The water drawing pipeline 1 is provided with a plurality of water drawing holes 11. The plurality of water drawing holes 11 are uniformly distributed from one end of the water drawing pipeline 1 to the other end of the water drawing pipeline 1 to be arranged in a line together. An auxiliary pipeline 12 is also arranged in the water drawing pipeline 1. In particular, as shown in fig. 2. A plurality of water suction holes 121 are formed in the auxiliary pipe 12, and the water suction holes 121 are arranged in a plurality of rows and are distributed from one end of the auxiliary pipe 12 to the other end. Thus, the water suction holes 121 are uniformly surrounded around the auxiliary duct 12. The auxiliary pipe 12 can communicate with the inside of the water scooping pipe 1 by means of the water suction holes 121. The surface of the auxiliary pipeline 12 is further provided with an isolation net, and the isolation net covers the water suction holes 121. The isolation net can be made of gauze and other materials which can filter water to a certain extent. Meanwhile, the contents are as shown in fig. 1 and fig. 3. The diameter of the auxiliary pipe 12 is smaller than the diameter of the scoop pipe 1 so that a gap exists between the auxiliary pipe 12 and the inner wall of the scoop pipe 1. The gap between the auxiliary pipeline 12 and the water drawing pipeline 1 is filled with stones.
Preferably, a separation net is also arranged at the end of the water drawing pipe 1 far away from the ground, and a separation net is also arranged at the end of the auxiliary pipe 12 far away from the ground, so as to prevent stones from leaking out of the end of the water drawing pipe 1.
In actual use, a plurality of water pumping pipelines 1 can be arranged to surround the periphery of the working well. The water drawing pipeline 1 and the working well are arranged at intervals, and the interval distance is 30cm-50 cm. Meanwhile, the length of the water drawing pipeline 1 is greater than the depth of the working well, and the length of the water drawing pipeline 1 is 2m-3m longer than the depth of the working well, so that the underground water below the working well can be drawn. When the device is installed, one side of the water drawing pipeline 1, which is provided with the water drawing holes 11, is set to be close to one side of the working well, so that the water drawing holes 11 face the working well, and further, groundwater with different depths between the working well and the water drawing pipeline 1 can enter the water drawing pipeline 1 through the water drawing holes 11. After the water entering the water intake pipe 1 passes through the stones, the water will rapidly enter the auxiliary pipe 12 through the water suction holes 121. The water pump is started, and the water in the auxiliary pipeline 12 can be quickly pumped out. And stopping pumping water after the pipeline construction inside the working well is finished. Meanwhile, the utility model can also be applied to the construction of deep-foundation elevator shafts. Therefore, under the limitation of the water pumping pipeline 1, the water pump can only pump the underground water between the water pumping pipeline 1 and the working well, so that the phenomenon that the underground water is too large in pumping range, a large number of cavities occur in the underground water, and the road surface around the working well is settled and collapsed is effectively avoided.
Wherein, fill the stone between auxiliary line 12 and draw water pipeline 1, on the one hand can fix a position auxiliary line 12 to avoid auxiliary line 12 to take place to incline under the rivers effect, influence the normal clear of work of drawing water, on the other hand can utilize capillary effect with auxiliary line 12 cooperation jointly, has promoted the inside surface of water height of auxiliary line 12 and has reduced the groundwater of periphery to drawing water pipeline 1 flow when to water pump power demand, thereby has improved the effect of drawing of groundwater.
The small stones and sundries in the filled stones can be effectively isolated through the isolation net, and the stones or sundries are effectively prevented from entering the auxiliary pipeline to influence the normal operation of water pumping.
