Abstract
The utility model relates to a strong-suction downcomer well, which comprises a well pipe (1). A well cover (2) is arranged at the top end of the well pipe (1); a drainage hole (2-1) is formed in the well cover; a drainage pipe (3) is inserted in the drainage hole (2-1); the top end of the drainage pipe (3) is exposed out of the well cover (2); a self-priming pump (5) is arranged on the ground; and the self-priming pump (5) is connected with the top end of the drainage pipe (3) through a connecting pipe (4); a water inlet (7) is formed in the pipe wall at the bottom end of the well pipe (1); and the water inlet (7) is connected with a filter (6). The strong-suction downcomer well disclosed by the utility model has a simple structure; construction difficulty and cost are reduced, and water discharge efficiency is improved; and manpower is saved, so that construction is convenient, and operability is strong.
Description
Technical field
The utility model relates to a kind of strong suction precipitation pipe well, relates to underground construction precipitation technical field.
Background technology
Tube well dewatering have precipitation depth big, be suitable for characteristics such as the stratum is wide; So be highly suitable for the work progress of the big and underground construction that high water level is regional of groundwater run off; Adopt the method for tube well dewatering to reduce soil moisture in layer; Not only can improve the soil consolidation strength, reduce the artesian water jacking force, and can ensure the construction safety of underground construction.At present traditional tube well dewatering is made up of structures such as vacuum pump, suction pump, well casings, on the well lid of well casing, is provided with aspirating hole, drain hole and cable aperture, complex structure not only, and increased difficulty of construction and cost.
Summary of the invention
The utility model is to overcome above-mentioned deficiency, and a kind of simple in structure, easy construction and the low strong suction precipitation pipe well of cost are provided.
The purpose of the utility model is achieved in that
The utility model is inhaled the precipitation pipe well by force, comprises well casing, and the top of said well casing is provided with well lid; Offer drain hole on the said well lid, insert gutter in the said drain hole, well lid is exposed on the top of said gutter; Ground is provided with self priming pump; Said self priming pump links to each other through tube connector with the top of gutter, and the tube wall of said well casing bottom is provided with water inlet, and said water inlet links to each other with strainer.
Compared with prior art, the beneficial effect of the utility model is:
It is simple that the utility model is inhaled the downcomer well construction by force, not only reduced difficulty of construction and cost, simultaneously also improved water outlet efficient, saved manual work, makes easy construction, workable.
Description of drawings
Fig. 1 inhales the structural representation of precipitation pipe well by force for the utility model.
Wherein:
Well casing 1
Well lid 2
Drain hole 2-1
Gutter 3
Tube connector 4
Self priming pump 5
Strainer 6
Water inlet 7.
The specific embodiment
Referring to Fig. 1, the utility model is inhaled the precipitation pipe well by force, comprises well casing 1; The top of said well casing 1 is provided with well lid 2, offers drain hole 2-1 on the said well lid 2, inserts gutter 3 in the said drain hole 2-1; Well lid 2 is exposed on the top of said gutter 3, and ground is provided with self priming pump 5, and said self priming pump 5 links to each other through tube connector 4 with the top of gutter 3; The tube wall of said well casing 1 bottom is provided with water inlet 7, and said water inlet 7 links to each other with strainer 6.
Water level in well casing 1 arrives the bottom of gutter 3, thereby after getting into gutter 3, under the effect of self priming pump 5, water is extracted out in gutter 3.
In traditional tube well dewatering, use vacuum pump and suction pump simultaneously, and inhale by force in the precipitation pipe well at the utility model, only used self priming pump, self priming pump possesses the function of vacuum pump and suction pump simultaneously; On well lid, have only tap in addition, do not have cable aperture and aspirating hole, saved materials such as cable, thereby reduced cost, make device structure simple, manual work is saved in easy construction, and is workable, and the efficient of water outlet simultaneously also is improved.
Claims (1)
